[0054] Please refer to Figure 1 An embodiment of the utility model provides a control system, which may include a thermostat 100, and the thermostat 100 is used to connect to HVAC equipment 500 and control these HVAC equipment 500.

[0055] In some solutions, the control system also includes a terminal 200 and a gateway 400 .

[0056] The terminal 200 can be understood as any device or combination of devices having data processing capabilities and external communication capabilities. For example, it can be Figure 2 The mobile phone 201 in the figure, of course, in addition to the mobile phone 201, the terminal 200 can also be other devices, such as a computer, a car machine, a smart watch, a smart VR device, etc., which is not limited in this embodiment.

[0057] The gateway 400 may be understood as a gateway 400 of any network, which may be, for example, any one of a WIFI network (router 401), a ZIGBEE network, and a Bluetooth network (Bluetooth gateway 402); in the following description, the description is mainly based on the WIFI communication method.

[0058] In a further solution, the gateway 400 can access the Internet, thereby realizing data exchange with other devices connected to the Internet (such as the terminal 200, other external devices 600). In addition, the gateway 400 can be a gateway device dedicated to serving as a gateway (such as a router 401, a Bluetooth gateway 402), or can be other devices with gateway functions, such as a speaker with gateway functions, a display device with gateway functions, a wall switch with gateway functions, etc.

[0059] In some solutions, the control system may further include a server 300, and both the gateway 400 and the terminal 200 may interact with the server 300, and the data interaction between the gateway 400 and the terminal 200 may be implemented based on the server 300. In some examples, the server 300 may be a cloud 301 (cloud server), which may play a role in data storage and processing.

[0060] In one embodiment, Figure 2 As shown, the gateway 400 is a WIFI gateway (i.e., a router 401), and the corresponding network is a WIFI network. The thermostat 100 can join the WIFI network after network configuration, and access the Internet through the router 401, and then communicate with the cloud 301. The terminal 200 is a mobile phone 201, and the mobile phone 201 can access the cloud 301 through cellular data, wireless local area network, etc. Other external devices 600 (such as temperature and humidity sensors) can also access the cloud 301 through the corresponding Bluetooth gateway 402 or router 401. Furthermore, the communication between the thermostat 100 and the mobile phone 201, and the thermostat 100 and other external devices 600 connected to the cloud 301 can be achieved through the cloud 301 as an intermediary.

[0061] The HVAC equipment 500, i.e., heating, ventilation and air conditioning equipment, is used to create an indoor environment to meet the user's comfort requirements for temperature, humidity, air quality, etc. There are many types of HVAC equipment 500, and the HVAC equipment 500 involved in this embodiment is the HVAC equipment 500 supported by the thermostat 100. In this embodiment, according to different control methods, these HVAC equipment 500 are divided into valve-type HVAC equipment (i.e., HVAC equipment controlled by controlling valves, such as fan coil central air conditioners, floor heating, valve-type fresh air systems, etc.) and protocol-type HVAC equipment (i.e., HVAC equipment controlled by signals, such as protocol-type fluorine machine central air conditioners, 485 fresh air fans, etc.). The thermostat 100 can exert control on these HVAC equipment, for example, but not limited to: control to enter a certain state: for example, turn on or off the air conditioner, turn on or off the floor heating, turn on or off the fresh air system; control to switch between multiple states: for example, switch the cooling and heating modes of the air conditioner, switch the opening and closing of the fresh air system, switch the opening and closing of the floor heating; control to change the working parameters: for example, adjust the cooling / heating temperature of the air conditioner, adjust the wind speed of the fresh air system, adjust the temperature of the floor heating, etc. Among them, the control of the valve-type HVAC equipment is achieved by controlling the action of its valve, and the control of the protocol-type HVAC equipment is achieved by sending the corresponding communication signal to it. According to the change of the type of HVAC equipment 500 connected to the thermostat 100, the specific content of the control and the controlled can be arbitrarily changed, and all do not depart from the scope of the embodiment of the utility model. At the same time, the description of the control of the HVAC equipment 500 by the thermostat 100 in the following text can also be understood with reference to the above content.

[0062] Existing HVAC equipment usually can only rely on the exclusive control panels provided by various manufacturers to manage the equipment. This dependence not only limits the user's freedom of choice, but also reduces the overall integration and operational convenience of the smart home system, because it means that when users install multiple HVAC equipment at home, they have to frequently switch between multiple different control interfaces and cannot enjoy a unified and smooth control experience. In addition, in the field of control of protocol-based HVAC equipment, the data communication standards adopted by various suppliers show significant diversity. Even between different brands or models of equipment within the same supplier, there may be significant differences in their data conversion protocols, which also increases the difficulty of managing these HVAC equipment in the same way through one thermostat. Therefore, it is crucial to seek an intelligent thermostat solution that can uniformly manage multiple types of HVAC equipment and is compatible with various data conversion standards to improve the versatility of equipment and user interaction experience.

[0063] Based on this, the utility model provides a thermostat control method, which gives the thermostat 100 strong compatibility, so that it can not only cross-domain control valve type and protocol type HVAC equipment of two major categories, but also achieve breakthrough intelligent adaptation for protocol type HVAC equipment models.

[0064] The following will elaborate on various implementations of the control method provided by the utility model. In addition, the technical features involved in the various implementations of the utility model described below can be combined with each other as long as there is no conflict between them.

[0065] See also Figure 3 , provides a control method for a thermostat, which control method can be applied to the thermostat 100 in the above-mentioned control system, and the thermostat 100 supports multiple types of HVAC equipment 500, including at least a first type of HVAC equipment 501 and a second type of HVAC equipment 502. As mentioned above, the first type of HVAC equipment 501 can be, for example, a protocol-type HVAC equipment, and the second type of HVAC equipment 502 can be, for example, a valve-type HVAC equipment, and the control methods between the two are different.

[0066] according to Figure 3 It can be seen that the control method at least includes steps S1 to S3. Among them:

[0067] S1. Receive control commands. The thermostat 100 can be controlled in a variety of ways, such as terminal direct control, cloud control, local control, etc. Furthermore, the control commands can also have a variety of sources, such as receiving control commands from the terminal 200 (mobile phone APP, smart speaker) through WIFI and Bluetooth communication, or receiving control commands input by the user in the local interface of the thermostat 100. According to the type of controlled HVAC equipment pointed to by the control command, this embodiment divides the control commands into multiple types (such as the first and second types of commands involved in subsequent embodiments) for controlling various types of HVAC equipment 500.

[0068] S2. When a first type of command is received, a corresponding control signal is sent to the auxiliary control module 3151; the auxiliary control module 3151 is preset with a changeable data conversion standard so that: after the auxiliary control module 3151 receives the control signal, it performs format conversion according to the currently set data conversion standard to convert the received control signal into a data format that can be recognized by the first type of HVAC equipment 501, and manipulates the first type of HVAC equipment 501 based on the converted data, thereby achieving control over them.

[0069] S3. When receiving the second type of command, the output on-off module 32 is adjusted to control the second type of HVAC equipment 502.

[0070] Specifically, when using the thermostat 100, the user needs to first set the data conversion standard in the auxiliary control module 3151 according to the first type of HVAC equipment 501 connected to the thermostat 100, so that when the first type of command is received, the data format converted by the auxiliary control module 3151 can be successfully recognized by the HVAC equipment 500.

[0071] When the user controls the thermostat 100 in various ways, if the control command is a first-class command for the first-class HVAC equipment 501, the thermostat 100 sends a corresponding control signal to the auxiliary control module 3151. The auxiliary control module 3151 converts the control signal into a format recognizable by the first-class HVAC equipment 501 according to the preset data conversion standard, and sends it to the corresponding device to control the first-class HVAC equipment 501. If the control command is a second-class command for the second-class HVAC equipment 502, the thermostat 100 adjusts the output on-off module 32 to directly control the second-class HVAC equipment 502.

[0072] According to the control method provided in this embodiment, the thermostat 100 is allowed to support multiple types of HVAC equipment 500. When the user's home is equipped with multiple types of HVAC equipment 500, it is no longer necessary to set up a control panel specifically for each HVAC equipment 500. The method provided in this embodiment makes the thermostat 100 a universal thermostat, which can replace the temperature control device configured in the HVAC equipment itself, and can provide intelligent control for the HVAC equipment. For example, if a user purchases a fluorine machine central air conditioner at home, through the solution of this embodiment, the thermostat 100 can directly replace the control panel originally carried by the fluorine machine central air conditioner, and provide the fluorine machine central air conditioner with networking capabilities.

[0073] Furthermore, the innovative design of the thermostat control method provided in this embodiment not only gives the thermostat unprecedented compatibility and flexibility, but also realizes the dynamic change of the built-in data conversion standard of the auxiliary control module 3151 in the protocol-based HVAC equipment control, thereby achieving precise "on-demand adaptation", providing users with a wider range of choices to meet different usage needs.

[0074] Furthermore, the data conversion standard currently set by the auxiliary control module 3151 is set after making a selection from a plurality of preset data conversion standards; each data conversion standard corresponds to a specific first-category HVAC equipment 501. Specifically, a plurality of optional data conversion standards are pre-configured, and each data conversion standard corresponds to a first-category HVAC equipment 501 under a certain supplier or a subcategory (brand and / or model) of the supplier. Specifically, the specific content of the data conversion standard of its equipment can be obtained by negotiation with the supplier, and then configured as an optional data conversion standard so that the supplier's equipment is supported. The pre-configuration here can be understood as a plurality of data conversion standards pre-stored in the cloud or the auxiliary control module 3151 locally, and a selection is made from a plurality of preset data conversion standards. It can also be understood as a selection made locally on the thermostat or through a terminal.

[0075] Furthermore, the user can select a matching data conversion standard for the auxiliary control module 3151 based on the first type of HVAC equipment actually connected to the thermostat 100, so as to realize dynamic adjustment of the specific models of protocol-based HVAC equipment supported by the thermostat 100, thereby making the thermostat highly configurable and dynamically adaptable, and being able to better meet the diverse needs of users.

[0076] Here is a possible way to set data conversion standards:

[0077] The auxiliary control module 3151 receives a specific configuration command and adjusts the data conversion standard stored internally according to the configuration command; after the configuration is completed, during normal operation, the auxiliary control module 3151 will convert the format of the control signal according to the set data conversion standard.

[0078] There are two ways to generate configuration commands: the first way is that the user generates it after making a selection from a variety of preset data conversion standards; the second way is that when the auxiliary control module 3151 successfully connects to the first type of HVAC equipment 501, it is automatically downloaded through the cloud based on the identified equipment brand and / or model.

[0079] When the configuration command is generated by the first method, the control method also includes: establishing communication between the auxiliary control module 3151 and a terminal 200; the auxiliary control module 3151 receives the configuration instruction sent by the terminal 200, and sets the data conversion standard based on the configuration instruction; the configuration instruction is generated after a plurality of optional setting items displayed on the terminal 200 are selected by the user; each setting item represents an optional data conversion standard.

[0080] The configuration instruction may be sent directly to the auxiliary control module 3151 , or may be sent indirectly, for example, through the cloud, a gateway, or may be first sent to the main control module 135 and then sent by the main control module to the auxiliary control module 3151 .

[0081] Setting the data conversion standard based on the configuration instruction can be understood as setting / resetting the preset data conversion standard to a data conversion standard that matches the target setting item selected by the user on the terminal according to the instructions of the configuration instruction. For example, according to the configuration instruction, the corresponding data conversion standard is specified as the set data conversion standard among the multiple data conversion standards stored locally. For another example, according to the configuration instruction, the corresponding data conversion standard is downloaded from the specified address in the cloud, thereby eliminating the need to store a large amount of data locally and making no changes to the hardware, making the product more scalable.

[0082] In some examples, the user can specify the required data conversion standard for the auxiliary control module 3151 through the host computer software. Specifically, when the configuration command is generated by the first case, the auxiliary control module 3151 establishes a connection with the host computer software of the mobile phone, and the host computer software can be, for example, an application (APP) or a WeChat applet, an Alipay applet, etc., so that the user can select from a variety of optional setting items through the interactive interface of the host computer software to generate the configuration instruction. Each optional setting item represents an optional data standard, wherein the optional setting item can be presented in a variety of ways in the interactive interface: for example, directly displaying the version number of the data conversion standard, based on the version number, the user can identify and select the required data conversion standard. For another example, displaying the brands and / or models of multiple HVAC equipment 500, the user makes a selection from the multiple HVAC equipment 500 displayed based on the HVAC equipment 500 actually connected to the thermostat 100.

[0083] In a further example, the auxiliary control module 3151 uses Bluetooth technology for wireless communication, and the upper computer software uses the WeChat applet as the operating platform. The user searches and connects to the Bluetooth of the auxiliary control module 3151 through the applet to achieve direct wireless communication between the two.

[0084] In a possible application scenario: the user wants to control a fluorine machine central air conditioner, which adopts the Modbus protocol format (i.e., data conversion standard), then the user can search and connect the Bluetooth of the auxiliary control module 3151 through the WeChat applet, and then select the Modbus protocol format for the auxiliary control module 3151 on the interface provided by the applet. In actual use, the user enters the desired temperature setting value on the control interface of the thermostat 100 to generate the first type of command, and the main control module 135 of the thermostat 100 sends the control signal corresponding to the command to the auxiliary control module 3151, and the auxiliary control module 3151 converts the signal into the Modbus communication protocol format that the air conditioner can recognize, and sends it to the air conditioner unit via wired or wireless means, so that it performs the corresponding work according to the instruction.

[0085] In addition, the thermostat 100 has a main control module 135 , which has a wireless communication function and can be remotely connected to the user's smart terminal 200 .

[0086] The control method further includes: independently operating the wireless communication function of the main control module 135 and the communication function of the auxiliary control module 3151. Based on the establishment of a direct communication relationship between the terminal 200 and the auxiliary control module 3151, the user can use the interface provided by the host computer software to directly send a control command to the auxiliary control module 3151 to control the first type of HVAC equipment 501 connected to the auxiliary control module 3151, and the control path does not pass through the main control module 135, so as to ensure that even if the wireless communication of the main control module 135 is not feasible, the user can still control the first type of HVAC equipment 501 through the communication path with the auxiliary control module 3151.

[0087] Furthermore, the output on-off module 32 includes a first relay component and a second relay component.

[0088] When the second type of command is received, the output on-off module 32 is regulated to control the second type of HVAC equipment 502 connected thereto; specifically, it includes: regulating the first relay component to control the valve of the fan coil central air conditioner and / or floor heating in the second type of HVAC equipment 502; and / or regulating the second relay component to control the fan of the valve-type fresh air system in the second type of HVAC equipment 502.

[0089] The first relay component may include one or more relays, and similarly, the second relay component may also include one or more relays, and the relay type may be different depending on the second type of HVAC equipment 502 being controlled. For example, the relays for controlling the high, medium, and low gears of the fresh air system may be single-pole single-throw relays, while the relays for controlling floor heating or fan coils may be single-pole double-throw relays. How each relay component specifically controls the valve or fan of the second type of HVAC equipment 502 will be described in detail in the subsequent product embodiments of the utility model, and will not be repeated here.

[0090] Furthermore, according to this embodiment of the utility model, the output on-off module 32 of the thermostat 100 includes two groups of relay components, the first group is used to control the valves of the fan coil central air conditioner and water floor heating, and the second group is used to control the fan of the fresh air system; when receiving the second type of command, the thermostat 100 will adjust the two groups of relays respectively to achieve precise control of different types of second type HVAC equipment 502.

[0091] The types of HVAC equipment that can be controlled by existing thermostats are fixed, that is, they are determined when the equipment leaves the factory and cannot be changed. This is not conducive to adapting to the different types of HVAC equipment in various usage scenarios, resulting in poor product versatility and flexibility in applicable scenarios.

[0092] In addition, in the current thermostat control method or thermostat, the types of HVAC equipment controlled are often preset at the factory and cannot be adjusted according to subsequent changes. This constitutes an obvious limitation in the face of diverse usage scenarios, especially when different environments need to match different types of HVAC equipment. Due to this type of fixedness, it is difficult for the product to meet a wide range of application needs, and its general performance and flexibility in adapting to complex scenarios are greatly reduced, reducing user satisfaction and ease of use in different occasions. Based on this, an embodiment of the utility model provides a thermostat control method that gives the thermostat the ability to change the type of controlled HVAC equipment at any time.

[0093] Specifically, in the control method of the thermostat, before receiving the control command, the control method further includes S10 to S30. Among them:

[0094] S10, receiving the user's selection of the type of HVAC equipment 500. The selection may be, for example, a visual selection process locally on the thermostat 100. The user interface of the thermostat 100 provides selection options for the type of HVAC equipment 500. The local visual selection process can, to a certain extent, prevent the user from making a wrong selection, which may result in the type of HVAC equipment not matching the type actually connected to the thermostat and being unable to be controlled. In some examples, such as Figure 4As shown, the optional HVAC equipment 500 types include but are not limited to air conditioning, floor heating and fresh air, among which air conditioning is subdivided into fluorine machine (protocol type fluorine machine central air conditioning), valve type (fan coil type central air conditioning), floor heating has valve type floor heating, and fresh air is valve type (valve type fresh air system), 485 (protocol type fresh air system). On this basis, in this embodiment, all valve type HVAC equipment are divided into the second type of HVAC equipment 502 (fan coil type central air conditioning, valve type floor heating, valve type fresh air system), and all protocol type HVAC equipment are divided into the first type of HVAC equipment 501 (protocol type fluorine machine central air conditioning, protocol type fresh air system).

[0095] S20. Generate a corresponding control interface according to the selected target HVAC equipment type. By allowing the user to independently select the target equipment type, the control interface can be switched at any time according to the actual needs of the user. For example, when the thermostat 100 receives input from the user to reselect the target HVAC equipment type during use, the thermostat 100 can dynamically switch to the corresponding control interface according to the user's reselection, thereby enabling the target HVAC equipment type of the thermostat 100 to be changed at any time according to the user's needs.

[0096] S30, displaying the generated control interface, and generating the first type of command and / or the second type of command through the manipulation of the interface, so as to realize the manipulation of the first type of HVAC equipment 501 and / or the second type of HVAC equipment 502. Specifically, the first type of command generated by the user's operation on the control interface is transmitted to the auxiliary control module 3151 for execution, and the second type of command generated is transmitted to the output on-off module 32 for execution. In some examples, the control that can be realized by the control interface can include, for example, but not limited to, on / off, temperature setting, wind speed adjustment, mode switching, etc. Among them, when the user selects multiple types of HVAC equipment at the same time, separate control interfaces are generated respectively, that is, each control interface occupies a separate screen.

[0097] Furthermore, the control method of this embodiment provides visual equipment selection and automatically generates a corresponding control interface based on the type of HVAC equipment selected by the user. The user can issue control commands based on the control interface, thereby improving the versatility and adaptability of the thermostat 100 and realizing dynamic changes in the target HVAC equipment type controlled by the thermostat 100.

[0098] An example of a possible application scenario: the user installs a floor heating system in the living room and a protocol fresh air system in the bedroom. After connecting the cables between the floor heating, the protocol fresh air and the thermostat, the user only needs to select the two device types of fresh air (485) and floor heating (valve type) on the corresponding device type configuration interface of the thermostat 100 to generate the corresponding control interface. The user can then switch the control interface by sliding the screen interface, for example Figure 5aAs shown, swiping left from the main interface can switch to the first screen, which displays the protocol fresh air system (fresh air (485)) control interface. The user's manipulation through the control interface generates a first type of command for controlling the protocol fresh air system. The user can turn on / off the fresh air system and adjust the wind speed parameters of the fresh air on this interface. Continuing to swipe left on the first screen interface can switch to the second screen, which displays the floor heating control interface. The user's manipulation through the control interface generates a second type of command for controlling the floor heating. The user can turn on / off the floor heating, adjust the temperature parameters of the floor heating, and view the temperature and humidity information on this interface. In subsequent use, if the user needs to control other types of equipment, he only needs to reselect the corresponding HVAC equipment type in the equipment type configuration interface and click Confirm. The thermostat will restart and reset the control interface, so that the user can change the target HVAC equipment type to be controlled by the thermostat without performing other complicated settings.

[0099] Furthermore, the thermostat 100 can remotely connect to the user's terminal 200 through the wireless communication function of the main control module 135 (the communication function is provided by the communication module 134), so that the user can complete at least one of the tasks of network configuration, parameter setting and remote control operation of the thermostat 100 through the APP pre-installed on the terminal 200.

[0100] The control command received by the thermostat 100 may be derived from a command input by a user through the thermostat 100 itself, sent by an APP to the main control module 135 , and / or sent by the host computer software to the auxiliary control module 3151 .

[0101] When the control command comes from an instruction sent by the host computer software to the auxiliary control module 3151 , the control method further includes: directly regulating the auxiliary control module 3151 to control the first type of HVAC equipment 501 .

[0102] When the control command originates from the APP of the terminal 200, the control method further includes: receiving a control command triggered by the terminal 200, and determining whether the control command is a first-category command and / or a second-category command according to the target HVAC equipment type.

[0103] Specifically, the user can trigger the control command through the APP. After the thermostat 100 receives the control command triggered by these terminals 200, it determines whether the command belongs to the first category or the second category based on the target HVAC equipment type previously selected by the user; for the first category of commands, it is forwarded to the auxiliary control module 3151 for format conversion and issuance, and for the second category of commands, it directly regulates the output on-off module 32 for execution.

[0104] The interactive interface of the APP, i.e. the corresponding interactive method, can be, for example Figure 5bAs shown: When the user does not select any HVAC equipment type on the thermostat 100, the interactive interface of the APP only displays the temperature and humidity values ​​(for example Figure 5b In the figure (a), the interface displays "Room temperature: 27°C Humidity: 43%"), and reminds the user to select the access device type (e.g. Figure 5b In Figure (a), the reminder text on the interface reads “Please select the access device type on the device screen”). When the user selects the corresponding HVAC equipment type on the thermostat 100, the thermostat 100 will report data related to the selected target HVAC equipment type, so that the APP can update the interactive interface to the control interface of the corresponding HVAC equipment type. Furthermore, the interactive interface of the APP can be dynamically updated according to changes in the target HVAC equipment type selected by the user. If the user only selects one HVAC equipment type, the interactive interface of the APP will only generate an interactive interface for that HVAC equipment type, and will not generate interactive interfaces for other HVAC equipment types. If the user selects multiple HVAC equipment types, the interactive interface of the APP can generate interactive interfaces for multiple HVAC equipment types, and the user can switch between multiple interactive interfaces. Figure 5b In Figure (b), the user selects the interactive interface corresponding to three HVAC equipment types. The user can switch the interactive interface through the three options of "air conditioning", "floor heating" and "fresh air".

[0105] In this example, the interaction interface of each sub-type of HVAC equipment under the general category of air conditioners can be shared. For a further example, when the interaction interface of each sub-type of HVAC equipment under the general category of air conditioners is shared, the user selects any sub-type under the general category of air conditioners (such as air conditioners (fluorine machines), air conditioners (valve type) or air conditioners (virtual)) on the thermostat 100, and the interaction interface of the APP is the same as Figure 5b As shown in Figure (b), this interface is a common interactive interface for HVAC equipment of various sub-types under the general category of air conditioners, including: status display, switch controls, air conditioner temperature adjustment, air conditioner mode adjustment, and air conditioner wind speed adjustment. The difference is that if the user selects air conditioner (fluorine machine) in the device type, when the thermostat 100 receives the control command for the air conditioner sent by the APP, it will be determined as a first-class command, and then the auxiliary control module 3151 will be adjusted to control the protocol-type fluorine machine central air conditioner. If the user selects air conditioner (valve type) in the device type, when the thermostat 100 receives the control command for the air conditioner sent by the APP, it will be determined as a second-class command, and then the output on-off module 32 will be adjusted to control the fan coil type central air conditioner.

[0106] Similarly, floor heating and fresh air can also be handled in this way. For example, when the interaction interface of each sub-type of HVAC equipment under the fresh air category is shared, the user selects any sub-type under the fresh air category (such as fresh air (485), fresh air (valve type) or fresh air (virtual)) on the thermostat 100, and the interaction interface of the APP is the same as Figure 5b As shown in Figure (c), this interface is a common interactive interface for fresh air, including: status display, switch controls, and fresh air fan wind speed adjustment. The difference is that if the user selects fresh air (485) in the device type, then when the thermostat 100 receives the control command for fresh air sent by the APP, it will be determined as a first-type command, and then the auxiliary control module 3151 will be adjusted to control the protocol-based fresh air system. If the user selects fresh air (valve type) in the device type, then when the thermostat 100 receives the control command for fresh air sent by the APP, it will be determined as a second-type command, and then the output on-off module 32 will be adjusted to control the fan of the valve-type fresh air system. The common interactive interfaces for floor heating are all as follows. Figure 5b As shown in Figure (d), it includes status display, switch controls, and temperature adjustment.

[0107] In some embodiments, before receiving the user's selection of the type of HVAC equipment 500, the control method further includes: displaying a preset main interface. The basic content of the main interface can be default or can be set by the user, for example Figure 5a As shown, the basic content of the main interface may include background images, date, time, network status, etc.

[0108] After receiving the user's selection of the type of HVAC equipment 500, the control method also includes: generating a shortcut control corresponding to the target HVAC equipment 500 type at a corresponding position of the main interface according to the selected target HVAC equipment 500 type; the shortcut control is used to control the target HVAC equipment 500.

[0109] The quick control is a configurable content of the main interface, and changes dynamically based on the user's selection of the HVAC equipment 500 type. When the user selects multiple HVAC equipment types, a quick control will be generated for each HVAC equipment type on the main interface, so that the HVAC equipment can be controlled only through the main interface without going through the specific control interface of the HVAC equipment.

[0110] like Figure 5a The user sets the quick controls at the bottom of the main interface. If there are multiple quick controls, they are arranged in order. During the configuration of the thermostat 100, the user selects two types of HVAC equipment, namely floor heating (valve type) and fresh air (485). Then two quick controls are generated on the main interface, such as Figure 5aAs shown, from left to right are the quick controls for fresh air and floor heating. Both quick controls are used to start / stop the device. When the user clicks the quick control for floor heating, the thermostat 100 will control the floor heating to start. For example, when the user clicks the quick control for floor heating again, the thermostat 100 will control the floor heating to turn off.

[0111] In addition, after the shortcut control is generated, the control method further includes: controlling the target HVAC device 500 according to the first manipulation applied to the shortcut control; and / or jumping from the main interface to the control interface of the corresponding HVAC device according to the second manipulation applied to the shortcut control. At least one of the number of clicks and the pressing duration between the first manipulation and the second manipulation is different, so that different control purposes can be achieved through different manipulations for the same shortcut control.

[0112] In some examples, the first manipulation is a single click, and the second manipulation is a long press for more than 3 seconds, and then if a shortcut control is single-clicked, the thermostat 100 will directly control the corresponding HVAC device 500, such as turning on / off the HVAC device 500. If a shortcut control is long pressed for more than 3 seconds, the thermostat 100 will directly jump from the main interface to the control interface of the HVAC device 500 corresponding to the shortcut control, and then the direct jump to the HVAC device control interface is realized through the second manipulation, avoiding the tedious process of switching screen by screen to find the required control interface.

[0113] In addition, current temperature control technologies face certain limitations in application, mainly reflected in their control capabilities being limited to directly controlling the physical HVAC equipment connected to them through wired methods. This means that once the HVAC equipment is installed far away from the thermostat, especially in environments with large spans or inconvenient wiring, the traditional wired connection method is not only costly to implement, but also poses considerable challenges at the physical level, severely limiting the deployment flexibility and coverage of the thermostat.

[0114] Based on this, an embodiment of the utility model also provides a thermostat control method, which aims to give the thermostat the ability to build and manage virtual HVAC equipment, and design a virtual control interface that matches it. Through the bridge role of the cloud platform or the intelligent binding technology between devices, these virtual avatars can accurately correspond to and remotely control the physical HVAC equipment actually installed in various environments, thereby cleverly realizing the "virtual and real integration" in the field of HVAC equipment control.

[0115] Specifically, in this embodiment, before receiving the control command, the control method further includes S100 and S200.

[0116] S100, by selecting a target virtual HVAC device from a plurality of virtual HVAC devices, a virtual control interface corresponding to the device type of the target virtual HVAC device is generated. The virtual HVAC device should be understood as a non-physical HVAC device, and the thermostat interface displays these selectable virtual HVAC devices in the form of icons or texts. Different device types require different control functions, and thus different device types correspond to different control interfaces.

[0117] S200 , displaying the virtual control interface, and adjusting a communication module 134 to control an external device 600 that has established a communication relationship with the thermostat 100 according to the control received by the virtual control interface.

[0118] It is worth noting that since the target virtual HVAC device only indicates the device type and is not associated with any physical controlled HVAC device 500, in the initial state after the virtual control interface is generated, it cannot control any physical controlled HVAC device 500. In other words, before the user configures the corresponding physical controlled HVAC device 500 for the virtual control interface, the virtual control interface is in a free state, and the control events issued by the thermostat 100 based on the manipulation received by the virtual control interface cannot trigger any physical controlled HVAC device 500.

[0119] After the virtual control interface is generated, the user needs to further configure the corresponding physical HVAC equipment 500 for the virtual control interface. Depending on the different physical controlled HVAC equipment 500 configured by the user, the physical HVAC equipment 500 that the virtual control interface can match and control is different, and thus the physical HVAC equipment 500 that the virtual control interface can match and control in this embodiment is changeable. In other words, the configuration of the virtual control interface is divided into two steps: first, a virtual control interface in a free state that is not used to control any physical HVAC equipment 500 is generated, and then the corresponding physical HVAC equipment 500 is further matched to the virtual control interface in the free state. The selection of the device type of the virtual control interface and the selection of the physical controlled HVAC equipment 500 that it can control are both freely defined by the user.

[0120] Furthermore, the control method provided in this embodiment generates a corresponding virtual control interface based on the virtual HVAC equipment selected by the user. The control interface truly simulates the main control elements and operation methods of the physical controlled HVAC equipment 500. Subsequently, by further associating the virtual control interface with the control items of the physical HVAC equipment 500, the interaction between virtual and reality is realized, which greatly improves the flexibility and convenience of the control of the thermostat 100.

[0121] like Figure 5c A method for selecting a target virtual HVAC device from multiple virtual HVAC devices is given, such as Figure 5cAs shown, the user specifically manipulates the control screen 14 switch to enter a predetermined configuration interface, which displays multiple virtual HVAC devices for selection, such as Figure 5c As shown, air conditioning, floor heating and fresh air all correspond to the "virtual" option, which is used for the user to select the desired target virtual HVAC equipment. After the user selects fresh air (virtual) and floor heating (virtual), the thermostat 100 generates a corresponding virtual control interface.

[0122] Further, in S200, the control communication module 134 controls the external device 600 that establishes a communication relationship with the thermostat 100, specifically including: sending a first event associated with the function control action currently triggered on the virtual control interface to the gateway 400 and / or the cloud 301, so that the gateway 400 / cloud 301 can determine a matching scene in the stored execution scenes, and control the function of the external device 600 defined by the scene to be executed.

[0123] Specifically, the first event is associated with the current action of the target function control, and the target function control is the function control currently triggered on the virtual control interface, so that: the gateway 400 and / or the cloud 301 can determine the matching execution scene in the stored execution scene, and control an executable function of the external device 600 defined by the execution scene to be executed; the execution scene stored by the gateway 400 and / or the cloud 301 is pre-defined by the user at the terminal 200; each execution scene defines a mapping relationship between an action of a function control of the virtual control interface and at least one executable function of at least one external device 600. The external device 600 can be a physical HVAC device. Of course, in special usage scenarios, the external device 600 can also be other smart devices, such as air purifiers, sweeping robots, etc.

[0124] In the normal use stage, the first event sent out by the thermostat 100 based on the manipulation applied by the user on the virtual control interface is target-oriented and can trigger the corresponding executable function of the physical HVAC device 500 matched therewith. This control method uses the gateway 400 and / or the cloud 301 as a bridge, so that the thermostat can control a wider range of external devices. The user is allowed to change the mapping relationship between each functional control on the virtual control interface and the external device 600 at any time to match different physical HVAC devices 500, so as to dynamically adjust the matching relationship between the virtual device and the physical controlled device, that is, the physical HVAC device 500 that can be controlled by the virtual control interface can be changed and expanded according to actual needs. For example, the user can match different control items of a physical HVAC device 500 to each functional control of a virtual control interface, so that the physical controlled HVAC device 500 controlled by each functional control of a virtual control interface is the same, but the specific executable functions of the physical controlled HVAC device 500 controlled are different.

[0125] For example Figure 5c As shown, the virtual control interface corresponding to the fresh air system includes a switch control and a wind speed switching control, wherein the switch control is configured to control the on / off function of a fresh air system, and the wind speed switching control is configured to control the wind speed switching function of the fresh air system, so that the virtual control interface is formed as a remote control interface of the fresh air system. Of course, the user can also match different physical controlled HVAC devices 500 to different functional controls of a virtual control interface, so that a virtual control interface can control multiple physical controlled HVAC devices 500. For example, in the virtual control interface corresponding to the fresh air system, the switch control is configured to switch the on / off function of the fresh air system, and the wind speed switching control is configured to switch the wind speed switching function of an air conditioner, so that the virtual control interface is formed as a remote control interface of two HVAC devices 500.

[0126] Furthermore, in the above embodiment, the problem that the thermostat 100 can only control a single device or a fixed scene and cannot flexibly adjust the control range according to user needs is solved through the bridge role of the gateway / cloud platform. By defining the execution scene, the function controls of the virtual control interface are associated with the executable functions of multiple physical HVAC devices 500, so that the thermostat 100 can control multiple devices and complex scenes, and improve the flexibility and scalability of the control.

[0127] A possible usage scenario of the above method is further described below: the user wants to control the floor heating in the living room and the protocol-type fluorine machine central air conditioner in the bedroom through a thermostat 100, wherein the thermostat 100 is installed in the living room and is wired to the floor heating valve through the output on-off module 32. Since the distance between the protocol-type fluorine machine central air conditioner in the bedroom and the thermostat 100 is too far, wiring is extremely troublesome. According to the solution provided in this embodiment, the user can virtualize a virtual control interface of a protocol-type fluorine machine central air conditioner through the thermostat 100, and add the thermostat 100 and the protocol-type fluorine machine central air conditioner to the network through the terminal 200, and then bind each function control on the virtual control interface with each control item of the protocol-type fluorine machine central air conditioner through the execution scene definition function of the terminal 200, and then store the corresponding execution scene in the cloud. For example, the execution scenario A is defined as the on / off function item of the protocol-type fluorine machine central air conditioner when the switch control on the virtual control interface is actuated, the execution scenario B is defined as the mode switching function item of the protocol-type fluorine machine central air conditioner when the mode switching control on the virtual control interface is actuated, and the execution scenario C is defined as the wind speed switching function item of the protocol-type fluorine machine central air conditioner when the wind speed switching control on the virtual control interface is actuated. In the subsequent use process, the user can directly control the living room floor heating connected to it through the output on-off module 32 of the thermostat 100, and wirelessly control the protocol-type fluorine machine central air conditioner in the bedroom through the virtual control interface provided by the thermostat 100. The specific process of controlling the protocol-type fluorine machine central air conditioner can be, for example: when the user clicks the switch control on the virtual control interface to the "on" action, the thermostat 100 will report the "switch control on" event to the cloud 301. The cloud 301 matches the stored execution scenario A based on the event, and based on the execution result defined by the execution scenario A (i.e., the on / off function of the protocol-type fluorine machine central air conditioner), it will send a "turn on the air conditioner" control command to the protocol-type fluorine machine central air conditioner, so that the working state of the protocol-type fluorine machine central air conditioner is adjusted to be consistent with the current action of the switch control on the virtual interface. The control principles of other functional controls (mode switching controls, wind speed switching controls) on the virtual control interface are similar. Furthermore, through a thermostat 100, the user can control both the floor heating in the living room and the protocol-type fluorine machine central air conditioner in the bedroom.

[0128] In further explanation, the user has a unique account and password on the corresponding application of the terminal 200 (such as the mobile phone 201), and adds smart devices after logging into the application based on the account and password. These smart devices can be some controlled devices (such as sweeping robots, smart window pushers, air purifiers, HVAC equipment, etc.), or some controlling devices (such as thermostats 100, etc.). Adding smart devices under the account can be understood as adding the device of the user, and the user has the authority to manage (such as deletion, control function execution, configuration parameters, etc.).

[0129] Among them, the HVAC equipment 500 and the thermostat 100 with networking capabilities can join the user's application through network distribution. Taking the network distribution of the thermostat 100 as an example, the specific process of the network distribution can be, for example:

[0130] When not in the network distribution state, the thermostat 100 is subjected to a specified operation to enter the network distribution mode. In a specific example, the specified operation may trigger a "reset network" option displayed thereon, and after the thermostat detects that the option is selected, it will clear the existing network distribution information and enter the network distribution mode.

[0131] In the network configuration mode, a network configuration request message is sent outward (the request message can be sent outward in the form of broadcast via the Bluetooth communication protocol) so that the terminal 200 can scan and search for the thermostat 100 through the corresponding application. After the user selects the thermostat 100 to be configured and enters the corresponding network configuration information, the terminal 200 sends the network configuration information to the corresponding thermostat 100 (the network configuration information can be sent to the thermostat 100 via Bluetooth direct connection), and the thermostat 100 connects to the network based on the network configuration information to complete the network configuration. In a specific example, when the thermostat 100 supports WIFI communication, the network configuration information can be, for example, the name and password of an available WLAN network of a router 401, and the thermostat 100 accesses the network of the router 401 based on the name and password.

[0132] After the network configuration is completed, the thermostat 100 is added to the user and managed by the user, and the thermostat 100 after the network configuration has the ability to connect to the network and can communicate with the gateway 400 and / or the cloud 301 to achieve remote control and configuration.

[0133] Further, in S200, the control communication module 134 controls the external device 600 that establishes a communication relationship with the thermostat 100, and may also include: sending the first event to the external device 600 according to the pairing relationship, and the first event is used to trigger the external device 600 to adjust the working state to match the action of the functional control being controlled on the virtual control interface.

[0134] The pairing relationship can be established in advance, and the external device 600 can be a HVAC device 500, or other smart device (such as a smart wall switch) that can establish a pairing relationship with the thermostat 100. The thermostat 100 can establish a pairing relationship with one external device 600, or it can establish a pairing relationship with multiple external devices 600 at the same time. After the pairing relationship is established, the thermostat 100 will send a first event to the switch device based on the manipulation received on the virtual control interface. The first event is used to trigger the on-off state of a control channel of the switch device to switch to match the action of the target function control, and the target function control is the function control manipulated on the virtual control interface.

[0135] Furthermore, according to this embodiment of the utility model, through the intelligent binding technology (pairing) between devices, the thermostat 100 can directly communicate and control the external device 600, without going through the gateway 400 or the cloud 301, the control efficiency is higher and the control path is more stable.

[0136] A possible application scenario is explained as follows: In this scenario, the user needs to control the wall switch through the thermostat, and then needs to establish a pairing relationship between the thermostat 100 and a wall switch. Specifically, by long pressing a function control on the virtual control interface of the thermostat 100 (for example, more than 4 seconds) and long pressing a button of the wall switch (for example, more than 4 seconds), the two enter pairing mode and send their own identification information (for example, a MAC address used to uniquely identify the device) to each other, so that the pairing is completed after the identification information of the other party is stored locally. When the function control of the virtual control interface is subsequently manipulated, the thermostat 100 will send an action event to the outside, which carries at least the identification information of the thermostat 100 and the current action of the controlled function control. After receiving the action event, the wall switch verifies that the identification information is already stored locally, that is, it determines that the action event is legal, and then controls the control channel of the corresponding button to switch to be consistent with the current action of the controlled function control. For example, if the current action of the controlled function control is on, the relay of the control channel of the control button is energized; if the current action of the controlled function control is off, the relay of the control channel of the control button is disconnected, thereby enabling the thermostat 100 to control other external devices 600 across categories.

[0137] The utility model also provides a thermostat 100, which can be used to implement a thermostat 100 control method provided in the above embodiment. Figure 6 to Figure 16 In the embodiment, the thermostat 100 provided in each embodiment can be understood as the hardware components and software programs required to implement the above-mentioned thermostat 100 control method. It is worth noting that the thermostat 100 provided in this part of the embodiment focuses on the detailed description of the hardware implementation scheme of the thermostat 100, and then the information interaction, execution process, implementation method, principle, function, effect, etc. between the modules in the following thermostat 100 embodiments are based on the same concept as the control method embodiment of the utility model. For specific contents, please refer to the description in the method embodiment of the utility model. For the understanding of the same features / schemes, this embodiment may not repeat them.

[0138] Specifically, if Figure 6As shown, the thermostat 100 at least includes a main control module 135, an auxiliary control module 3151, and an output on-off module 32. The main control module 135 is arranged on the control circuit board 13, the auxiliary control module 3151 and the output on-off module 32 are directly or indirectly arranged on the power circuit board 31, and the control circuit board 13 and the power circuit board 31 are connected through a pin and a female connector (131 and 311), so that the auxiliary control module 3151 and the output on-off module 32 are electrically connected to the main control module 135 respectively.

[0139] The main control module 135 is used to receive various control commands; when receiving the first type of command, it sends a corresponding control signal to the auxiliary control module 3151; when receiving the second type of command, it adjusts the output on-off module 32 to control the second type of HVAC equipment 502. The output on-off module 32 can be controlled by the main control module 135 to switch between the on and off states, and is used to control the second type of HVAC equipment 502. The auxiliary control module 3151 is preset with a changeable data conversion standard, and is interconnected with the main control module 135 through a communication interface, and is used to perform format conversion according to the currently set data conversion standard after receiving the control signal, so as to convert the received control signal into a data format that can be recognized by the first type of HVAC equipment 501, and control the first type of HVAC equipment 501 based on the converted data.

[0140] According to the above scheme, it can be known that this embodiment provides a thermostat 100, which can simultaneously control valve-type HVAC equipment 500 (such as fan coil central air conditioning, floor heating, valve-type fresh air) and protocol-type HVAC equipment 500 (such as protocol-type fluorine machine air conditioning, protocol-type fresh air). The thermostat 100 will receive control commands when working. This control command can come from devices such as the terminal 200, or from the operation of the thermostat 100 itself. The thermostat 100 controls the valve-type HVAC equipment 500 or the protocol-type HVAC equipment 500 according to the control command. If the protocol-type HVAC equipment 500 is controlled, the control command will be converted into a signal in a format that the HVAC equipment 500 can recognize through a protocol adapter module integrated in the thermostat 100, and then sent to the corresponding HVAC equipment 500 to ensure that the HVAC equipment 500 can recognize the signal and perform the corresponding function.

[0141] Furthermore, the thermostat 100 provided in this embodiment has strong compatibility and flexibility, and realizes dynamic changes in the data conversion standards built into the auxiliary control module 3151 in the protocol-based HVAC equipment control, thereby achieving precise "on-demand adaptation" and providing users with a wider range of choices to meet different usage needs.

[0142] In a possible usage scenario: the HVAC equipment 500 installed in the user's home is a fluorine machine central air conditioner A, which is provided by supplier 1, and the data conversion standard provided by supplier 1 is private data conversion standard 1. However, the fluorine machine central air conditioner A does not have the networking function and is configured with a control panel, and the user can control it through the thermostat 100 of this embodiment. Specifically, first, the thermostat 100 is connected to the fluorine machine central air conditioner A for communication, and then the data conversion standard in the auxiliary control module 3151 of the thermostat 100 is preset to private data conversion standard 1 through the terminal 200. Then, various types of control can be applied to the fluorine machine central air conditioner A through the thermostat 100 with the auxiliary control module 3151 as the medium. In this way, the thermostat 100 gives the fluorine machine central air conditioner A panel control function and networking intelligent function. If after using it for a period of time, the user finds that the previous fluorine machine central air conditioner A is not easy to use, and wants to replace it with a fluorine machine central air conditioner B, which is provided by supplier 2, and the data conversion standard provided by supplier 2 is private data conversion standard 2. After the user changes to the fluorine machine central air conditioner B, there is no need to replace the thermostat 100. The user only needs to connect the thermostat 100 to the fluorine machine central air conditioner B for communication, and then set the data conversion standard in the auxiliary control module 3151 to the private data conversion standard 2 to enable the thermostat 100 to control the fluorine machine central air conditioner B.

[0143] Furthermore, the data conversion standard currently set by the auxiliary control module 3151 is determined according to a configuration instruction, and the configuration instruction is generated after making a selection among a plurality of preset data conversion standards; each data conversion standard corresponds to a specific HVAC device 500.

[0144] Specifically, the auxiliary control module 3151 includes a protocol adapter unit, which is integrated inside the thermostat 100 and serves as a bridge for connecting protocol-based HVAC equipment. The data conversion standard in the protocol adapter unit is changeable, and the user can match the corresponding data conversion standard for the protocol adapter unit according to the HVAC equipment actually connected to the thermostat 100, so that the protocol adapter unit can convert the received control command into a data format that conforms to the stored data conversion standard.

[0145] In the example, the protocol adapter unit includes a control unit and a communication unit. The control unit establishes a connection with the host computer software through the communication unit, so that the user can specify the required data conversion standard from a variety of preset data conversion standards through the interactive interface of the host computer software. The communication unit uses Bluetooth technology for wireless communication, and the host computer software uses WeChat applet as the operating platform. The user searches and connects to the Bluetooth of the auxiliary control module 3151 through the applet to achieve direct wireless communication between the two.

[0146] Furthermore, the user can select a matching data conversion standard for the auxiliary control module 3151 based on the first type of HVAC equipment actually connected to the thermostat 100, so as to realize dynamic adjustment of the specific models of protocol-based HVAC equipment supported by the thermostat 100, thereby making the thermostat highly configurable and dynamically adaptable, and being able to better meet the diverse needs of users.

[0147] Furthermore, the thermostat 100 also includes a temperature and humidity detection unit 122, which is used to monitor the temperature and humidity conditions of the environment in which the thermostat 100 is located; the output on-off module 32 includes a first relay component and a second relay component; when a second type of command is received, the output on-off module 32 is regulated to control the second type of HVAC equipment 502 connected thereto; specifically including: according to the temperature and humidity detection data, regulating the first relay component to control the valve of the fan coil central air conditioner and / or floor heating in the second type of HVAC equipment 502, and / or regulating the second relay component to control the fan of the valve-type fresh air system in the second type of HVAC equipment 502.

[0148] The temperature and humidity detection unit 122 may include a sensor for detecting temperature and humidity (eg, the first sensor 12 described below) and other peripheral circuits used in conjunction with the sensor.

[0149] The first relay assembly may include one or more relays, and similarly, the second relay assembly may also include one or more relays, and the relay types may vary depending on the second type of HVAC equipment 502 being controlled. For example, the relays for controlling the high, medium, and low gears of the fresh air system may be single-pole single-throw relays 313, while the relays for controlling floor heating or fan coil units may be single-pole double-throw relays 313.

[0150] In a specific example, for the control of water floor heating, the supply of hot water can be controlled by controlling the electric valve of the floor heating, thereby achieving the purpose of adjusting the floor heating temperature. For the control of valve air conditioners (fan coil central air conditioners), the cold water or hot water flowing through the coil can be controlled by controlling the opening and closing of the electric valve, and the fan can be controlled to blow out cold air or hot air at a set wind speed to adjust the temperature. The electric valves involved above include many types, and different types have different control methods. For example, a three-wire electric valve (such as a three-wire two-control electric valve) can be included, which has two control lines for opening and closing. When controlling, the two control lines need to be controlled separately. For example, when the valve opening line is connected, the electric valve opens, and when the valve closing line is connected, the electric valve closes. Further, a two-way motor control can be used. When the valve opening line is connected to the zero line, the motor turns left (or right), and the valve moves in the direction of the valve opening. When the valve closing line is connected to the zero line, the motor turns right (or left), and the valve closes. It can also include a two-wire electric valve, whose opening and closing control is completed by one wire. You only need to control the power state of one wire to control the opening and closing of the valve. The two-wire electric valve is divided into a normally open valve and a normally closed valve. The normally open valve is in the open state when the control line is not powered, and the normally closed valve is in the closed state when the control line is not powered. The fan coil can include two-pipe and four-pipe. In the two-pipe fan coil, one electric valve can be used to control a cold / hot coil to control the switch of cold / hot water, while in the four-pipe fan coil, two electric valves are required to control the cold water coil and the hot water coil respectively.

[0151] Furthermore, according to this embodiment of the utility model, the output on-off module 32 of the thermostat 100 includes two groups of relay components, the first group is used to control the valves of the fan coil central air conditioner and water floor heating, and the second group is used to control the fan of the fresh air system; when receiving the second type of command, the thermostat 100 will adjust the two groups of relays respectively to achieve precise control of different types of second type HVAC equipment 502.

[0152] Furthermore, the thermostat 100 further includes a screen 14, which is electrically connected to the main control module 135 and is used to display the control interface of each HVAC device 500. Before receiving the control command, the main control module 135 is also used to: receive the user's selection of the type of HVAC device 500. And according to the selected target HVAC device 500 type, a corresponding control interface is generated on the screen 14. Then, the generated control interface is displayed, and the first type of command and / or the second type of command are generated through the manipulation of the interface to realize the manipulation of the first type of HVAC device 501 and / or the second type of HVAC device 502.

[0153] Specifically, the thermostat 100 has a user input module, which has a screen 14 and provides a user interface. The user can select the required HVAC equipment type by clicking an icon or button on the screen 14. The main control module 135 includes a microcontroller and a corresponding control program. According to the HVAC equipment type selected by the user, the main control module 135 calls the corresponding control interface program stored in the memory to generate the control interface screen of the equipment. For example, if an air conditioner (fluorine machine) is selected, the control interface displayed includes function controls such as temperature and wind speed, which are used to control the temperature adjustment, wind speed switching and other function items of the air conditioner.

[0154] Furthermore, the thermostat of this embodiment supports visual device selection and automatically generates a corresponding control interface based on the type of HVAC equipment selected by the user. The user can issue control commands based on the control interface, thereby improving the versatility and adaptability of the thermostat 100 and realizing dynamic changes in the target HVAC equipment type controlled by the thermostat 100.

[0155] In addition, during the operation of the thermostat, the heat generated by its internal components may affect the micro-environment temperature measurement around the built-in humidity detection unit, thereby affecting the accuracy of the reading. In order to improve the accuracy of temperature and humidity measurement and ensure the reliability of ambient temperature, the thermostat of the utility model is designed with an innovative function that allows users to independently compensate for temperature and humidity values ​​(i.e., manually adjust the detection data (humidity value and / or temperature value) collected by the temperature and humidity detection unit 122) to make targeted corrections to obtain ambient temperature / humidity readings that are closer to the actual environment. In terms of specific implementation, the thermostat interface has a user-friendly opening of an adjustment module, giving users the ability to make fine-tuning corrections within plus or minus 10°C (with a step adjustment resolution of 1°C) on the original temperature reading measured by the temperature and humidity detection unit 122. This means that the user can make fine adjustments within ±10°C to the temperature value initially measured by the temperature and humidity detection unit according to the actual situation or perceived environmental differences (for example, the user is allowed to adjust the currently displayed temperature value within ±5°C through the thermostat interface), thereby compensating for the errors caused by factors such as internal heating, making the final displayed temperature result more accurate and close to the actual environmental state, significantly enhancing the adaptability and control accuracy of the thermostat under different working conditions. For example, during use, the user finds that the temperature value displayed by the thermostat is 30°C, but the actual ambient temperature is 26°C. At this time, the user can compensate the currently displayed temperature value by -4°C through the adjustment module provided by the thermostat. The thermostat will subtract 4 degrees Celsius from the actual measured temperature value of 30°C and display it on the interface as the final temperature value. Subsequently, according to the adjusted (corrected) temperature value, the first relay component is regulated to control the valve of the fan coil central air conditioner and / or floor heating in the second type of HVAC equipment 502, and / or the second relay component is regulated to control the fan of the valve-type fresh air system in the second type of HVAC equipment 502.

[0156] Furthermore, the thermostat 100 further includes a proximity sensor 132 for detecting whether a user is close to the thermostat 100. The proximity sensor 132 may be, for example, a microwave radar module, an infrared sensing unit, etc. to detect a human body.

[0157] Before receiving the user's selection of the type of HVAC equipment 500, the main control module 135 is also used to display a preset main interface on the screen 14; after receiving the user's selection of the type of HVAC equipment 500, the main control module 135 is also used to: display the main interface when it is determined that the user is approaching the thermostat 100; the main interface has a shortcut control; the shortcut control is a shortcut control corresponding to the target HVAC equipment 500 type generated according to the selected target HVAC equipment 500 type, and is used to control the target HVAC equipment 500.

[0158] Among them, the quick control belongs to the configurable content of the main interface, and changes dynamically based on the user's selection of the type of HVAC equipment 500. When the user selects multiple types of HVAC equipment, a quick control will be generated for each type of HVAC equipment on the main interface, so that the HVAC equipment can be controlled only through the main interface without going through the specific control interface of the HVAC equipment.

[0159] Furthermore, before receiving the control command, the main control module 135 is also used to:

[0160] By selecting a target virtual HVAC device from a plurality of virtual HVAC devices, a virtual control interface corresponding to the device type of the target virtual HVAC device is generated. The virtual control interface is displayed, and according to the control accepted by the virtual control interface, a communication module 134 is regulated to control the external device 600 that has established a communication relationship with the thermostat 100. The virtual HVAC device should be understood as a non-physical HVAC device. These optional virtual HVAC devices are displayed in the form of icons or text in the interface of the thermostat. Different device types require different control functions, and thus different device types correspond to different control interfaces.

[0161] Furthermore, the thermostat 100 provided in this embodiment can generate a corresponding virtual control interface based on the virtual HVAC equipment selected by the user. The control interface truly simulates the main control elements and operation methods of the physical controlled HVAC equipment 500. Subsequently, by further associating the virtual control interface with the control items of the physical HVAC equipment 500, the interaction between virtual and reality is realized, which greatly improves the flexibility and convenience of the control of the thermostat 100.

[0162] refer to Figure 7As shown, in order to further reveal the structure and working principle of the thermostat 100 of this embodiment of the utility model, a partial circuit structure schematic diagram of the thermostat 100 is illustrated.

[0163] Specifically, in this embodiment of the utility model, the main control module 135 uses an embedded SOC chip, is connected to the auxiliary control module 3151 through a serial port, is connected to the communication module 134 through a USB port, and is electrically connected to the output on-off module 32 through a driving circuit to drive the output on-off module 32. For example, Sigmastar's SSD201 chip, SSD201 is a highly integrated embedded SOC chip, the chip is based on ARM Cortex-A7 dual-core 1.2GHz; integrated hardware H.264 / H.265 video decoder; built-in 64MB DDR; built-in 2D graphics engine; supports TTL (RGB88, 1280*800) / MIPI (1920*2080) screen display driver interface; built-in Ethernet mac and PHY; built-in audio codec, etc.; supports Secureboot, AES / DES / 3DES cryptographic engine, secure boot and personalized authentication mechanism to protect the system. Among them, the SSD201 chip is connected to the auxiliary control module 3151 through the serial port, connected to the communication module 134 through the USB port, and electrically connected to the output on-off module 32 through the driving circuit to drive the output on-off module 32. The SSD201 chip is a high-level reset PM_RESET, AVDD1P2_MIPI (Pin75) is connected to a 0.1uF capacitor to ensure the internal LDO voltage regulation of the chip, DVDD_DDR_RX (Pin50) is connected to a 470nF~1uF capacitor to GND, GND_EFUSE (Pin24) is connected to a 10KΩ resistor to GND, and is not directly connected to the chip ePAD. SSD201 has built-in DDR2-1333, and DDR2 is powered by 1.8V. The ESD protection device ESD5V0B02-1006 is connected to the USB line, which has an ultra-low parasitic capacitance of 0.18pF and can be used in high-speed applications such as USB / DP / MDDI / PCIe / SATA. The protection capability reaches 23kV air discharge and 20kV contact discharge. SSD201 supports SPINAND and SPINOR startup, which are selected by the pull-up and pull-down resistors of PM_SPI_CLK. Pull-down starts from SPINOR, and pull-up SPINAND starts from spi nandflash.

[0164] Furthermore, in this embodiment of the utility model, the screen 14 uses an LCD touch screen to display the control interface of various HVAC equipment 500 generated by the main control module 135, for example, including a 4.0-inch LCD screen + touch screen + backlight. The main control module 135 controls the driving power supply through a MOS tube to control the on / off of the power supply, so as to control the power-on timing (supply power to and drive the screen 14 after the core board is powered on stably) to avoid abnormal operation of the whole machine due to problems with the power-on timing. In addition, through the MOS tube, the main control module 135 can also re-power on the screen 14 to reset the screen 14. ME2212AM6G is used as the LED driver chip for the backlight.

[0165] Furthermore, in this embodiment of the utility model, the proximity sensor 132 uses a circuit or a combination of circuits having both human body sensing and light sensing functions, such as Lite-On's LTR-X1503 chip, which uses IIC to communicate with the SSD201 chip of the main control module 135 .

[0166] Furthermore, in this embodiment of the utility model, the temperature and humidity detection unit 122 adopts a new generation of single-chip integrated temperature and humidity sensor GXHT30 developed by China Science and Technology Galaxy Core, which also communicates with the SSD201 chip of the main control module 135 through IIC.

[0167] Furthermore, in this embodiment of the utility model, the auxiliary control module 3151 can be understood as a circuit or a combination of circuits with data storage and processing capabilities, which can store the data conversion standards internally and support users to change the stored data conversion standards according to needs to adapt to specific HVAC equipment 50.

[0168] In some examples, the auxiliary control module 3151 specifically includes a protocol adapter unit and a 485 communication circuit, wherein the protocol adapter unit includes a control unit and a communication unit, and the control unit is pre-set with a changeable data conversion standard, which establishes communication with the terminal 200 through the communication unit, and then changes the data conversion standard based on the instruction of the terminal 200. The protocol adapter unit is interconnected with the 485 communication circuit, and the 485 communication circuit is provided with a 485 protocol fresh air interface for connecting to a protocol-based fresh air system. The protocol adapter unit also directly provides a bus protocol interface for connecting to a protocol-based fluorine machine central air conditioner.

[0169] The data conversion standard can be understood as a communication protocol for data conversion. It is understandable that the communication protocol used by the supplier is generally private, and different suppliers use different private communication protocols. Therefore, for a specific HVAC equipment 500, the specific content of the protocol is also specific. When purchasing HVAC equipment 500, users usually consider many factors, such as brand effect, equipment quality, equipment price, etc. Therefore, different users may purchase HVAC equipment 500 from different suppliers, brands / models. In this embodiment, the auxiliary control module 3151 is integrated into the thermostat 100, and a wiring port for connecting the HVAC equipment 500 (such as the communication terminal 316 involved in the following embodiment) is provided to the outside through the housing of the thermostat 100, so that the thermostat 100 of this embodiment has a wider versatility.

[0170] An exemplary circuit of the auxiliary control module 3151 may be, for example Fig.11 As shown, the protocol adapter unit and the communication unit are integrated into a wire controller module MD1 with control and communication functions. The 485 communication circuit is built with the MAX3485ESA chip. The wire controller module can establish a Bluetooth direct communication with the terminal 200 to configure its internal data conversion standard. The wire controller module MD1 communicates with the SSD201 chip of the main control module 135 through the serial port (S2-TX, S2-RX), and establishes a connection through the 485 bus and the 485 communication circuit to send signals for controlling the protocol fresh air system through the 485 communication circuit. In addition, Fig.11 As shown, the wire controller module MD1 and the 485 communication circuit are jointly provided with an interface for connecting to the first type of HVAC equipment through the J2 interface (the J2 interface can be understood as the communication terminal 316 involved in the embodiments below), for example Fig.11 Among them, interfaces 1 and 2 of J2 are used to connect the protocol-based fresh air system, and interfaces 3 to 8 are used to connect the protocol-based fluorine machine central air conditioner.

[0171] Furthermore, if Figure 8 As shown, in this embodiment of the utility model, in the output on-off module 32, the first relay component includes a single-pole double-throw relay 314 (RL4), and the second relay component includes three single-pole single-throw relays 313 (RL1, RL2 and RL3). Among them, the single-pole double-throw relay 314 is used to control the fan coil valve of floor heating or fan coil central air conditioning, and the three single-pole single-throw relays 313 are used to control the high, medium and low wind speed gears of the valve-type fresh air system or the high, medium and low wind speed gears of the fan coil central air conditioning. Furthermore, in this example, Figure 8As shown in the J1 port in FIG. 1 , when the user controls the fan coil central air conditioner through the thermostat 100, the single-pole double-throw relay 314 needs to be connected to the fan coil valve control port of the fan coil central air conditioner, and the three single-pole single-throw relays 313 need to be connected to the high, medium and low gear valves of the fan coil central air conditioner respectively, and then the fan coil valve is controlled to be opened and closed by controlling the single-pole double-throw relay 314 to achieve the purpose of cooling / heating, and the high, medium and low wind speeds are controlled by controlling the three single-pole single-throw relays 313. When the user controls the valve-type fresh air system through the thermostat 100, the three single-pole single-throw relays 313 need to be connected to the high, medium and low gear valves of the valve-type fresh air system respectively, so as to switch the high, medium and low wind speeds of the fresh air system by controlling the attraction / disconnection of the three single-pole single-throw relays 313. When the user controls the floor heating through the thermostat 100 , the single-pole double-throw relay 314 of the thermostat 100 needs to be connected to the water pipe valve of the floor heating, and then the heating of the floor heating is controlled by controlling the single-pole double-throw relay 314 .

[0172] Furthermore, the main control module 135 drives each relay in the output on-off module 32 through a driving circuit. Figure 7 and Figure 8 As shown, the driving circuit adopts ULN2003A Darlington tube, the SSD201 chip is connected to the input end of ULN2003A through RELAY-1 to RELAY-4, and the output end of ULN2003A is electrically connected to the control end of each relay of the output on-off module 32, so that the SSD201 chip can drive the output on-off module 32 through ULN2003A. Using a Darlington tube to drive multiple relays of the output on-off module 32 can effectively reduce the space volume occupied by the driving circuit. Each relay in the output on-off module 32 is connected to the outside through the wiring terminal 312. As for how to achieve the connection, it will be described in detail later, and will not be repeated here.

[0173] In addition, in this embodiment of the utility model, the temperature controller 100 also includes a power supply circuit, which includes a strong power supply conversion circuit (arranged on the power supply circuit board 31) and a weak power supply conversion circuit (arranged on the control circuit board 13), wherein the strong power supply conversion circuit adopts an isolated flyback switching power supply solution, which can output 5V / 1A to meet the power supply output of the load and chip on the control circuit board 13. The weak power supply conversion circuit is used to further convert the voltage output by the strong power supply conversion circuit into the power supply voltage required by each chip, for example, the BL8039 chip of Shanghai Belling is used to convert 5v into 3.3V, 1.8V and 1.0V, and respectively used to power the SSD201 chip, wherein the 1.8V voltage is used to power the DDR inside the SSD201 chip, and the 1.0V voltage is used to power the SSD201 chip core.

[0174] Furthermore, in this embodiment, there is a power-on timing requirement between 1V and 3.3V. 1V needs to be powered on after 3.3V is powered on. The specific principle of the 5V to 1V circuit can be as follows: Fig. 9 As shown, the main control module 135 adjusts the output voltage of the 5V to 1V circuit through the voltage adjustment port (such as SAR_GPIO1) to adjust the power supply voltage of the SSD201 chip. Fig. 9 In the circuit shown, the regulation principle of the power supply voltage of the SSD201 chip can be, for example: when the power is turned on, by pulling up SAR_GPIO1, the 5V to 1V circuit outputs a voltage close to 1V (actually (49.9+75) / 75*0.6V=0.9992V); after the power is turned on, by controlling SAR_GPIO1 to be pulled down, the power supply voltage of the SSD201 chip is controlled to be pulled down to about 0.9V (actually (49.9+100) / 100*0.6V=0.8994V) to achieve the effect of reducing power consumption.

[0175] Furthermore, in this embodiment of the present invention, the communication module 134 uses a circuit or a combination of circuits that have both WIFI and Bluetooth functions. For example, the SKI.WB800DCU.1B22322 module supports WIFI and Bluetooth 5.2, uses USB to communicate with the SSD201 chip of the main control module 135, and supports IEEE 802.11b / g / n / ax&BT5.2standard from 2.4-2.5GHz. The specific circuit schematic diagram of the SKI.WB800DCU.1B22322 module can be shown as follows: Fig.10 As shown, it is connected to the SSD201 chip of the main control module 135 through USB1_N and USBN_P. It is powered by 3.3V, and a decoupling capacitor is set on the USB data line to reduce the radiation of the USB line and reduce the interference to the sensitivity. RF is an antenna interface, and the impedance needs to be controlled according to 50Ω. In order to facilitate the adjustment of RF performance, a Π-type matching circuit is reserved between the RF port and the antenna, and this Π circuit is placed close to the antenna.

[0176] The following uses a specific scenario as an example to further explain the working principle of the thermostat 100:

[0177] For example, a user's home is equipped with a water floor heating system and a Daikin MX duct unit (4-core) central air conditioner. Taking this scenario as an example, the use principle of the thermostat 100 can be as follows:

[0178] When the user gets the thermostat 100 device, first connect the water floor heating system and the Daikin MX duct unit (4-core) central air conditioner to the thermostat 100. Connect the valve control line of the water floor heating system to the first relay component of the output on-off module 32, specifically to the RL4 relay port in the first relay component. The Daikin MX duct unit (4-core) central air conditioner is a protocol-type fluorine machine central air conditioner, so its terminal is connected to the terminal of the auxiliary control module 3151 of the thermostat 100, specifically, the S21 terminal of the Daikin MX duct unit (4-core) central air conditioner is connected to 5 to 8 (A1, B1, X, Y) of the external J2 port of the protocol adapter unit. It should be explained here that the wiring methods of different models of first-class HVAC equipment 501 and auxiliary control module 3151 may be different. During specific use, the user can perform wiring according to the specific model of HVAC equipment 500. In addition, the thermostat 100 can also provide a wiring instruction for all the first-class HVAC equipment 501 it supports when leaving the factory, so that the user can refer to the wiring.

[0179] Then, the thermostat 100 is connected to the neutral and live wires, and the power supply is turned on. When the power is turned on and the SSD201 is initialized and started, the SSD201 of the main control module 135 controls the output voltage of the 5V to 1V circuit to decrease to about 0.9V, and the screen 14 is lit, so that the screen 14 displays the preset main interface.

[0180] The user can then search for the Bluetooth of the auxiliary control module 3151 through the WeChat applet on the mobile phone 201 and establish a direct connection, and then select the data conversion standard corresponding to the Daikin MX duct unit (4-core) central air conditioner for the auxiliary control module 3151 on the WeChat applet. Based on the user's selection on the WeChat applet, the auxiliary control module 3151 automatically goes to the cloud 301 to download the corresponding data conversion standard and installs it locally for subsequent use.

[0181] At this time, the thermostat 100 is powered on for the first time and has not been configured by the user. Therefore, the system defaults to the best configuration, that is, the best control scheme of the thermostat 100: air conditioning (fluorine machine), fresh air (valve type), floor heating (valve type). The first screen of the thermostat 100 is the control interface of the air conditioning (fluorine machine), the second screen is the control interface of the fresh air (valve type), and the third screen is the control interface of the floor heating (valve type). The main screen displays the shortcut controls of these three HVAC devices 500, such as Fig.12 shown.

[0182] After that, the user can enter the setting interface of the thermostat 100 by pulling down from any interface, and the interface displays multiple setting options, such as Fig.13As shown, the "Main Screen Settings" option can be used to set the main screen, such as setting the content, background, layout, etc. of the main screen; the "Screen 14 Brightness" option can be used to adjust the brightness of the screen 14; the "System Settings" option can be used to make some settings for the thermostat 100 system, such as network information display, resetting the network, restarting the device, restoring the factory settings, etc.; the "Touch Feedback" option can be used to set the touch feedback of the screen 14, such as turning off / on the buzzer sound when touching; the "About This Machine" option can display some version information of the thermostat 100, such as the software version number, MAC address, etc.; the "Device Type" is used to enter the configuration interface of the HVAC device 500 type.

[0183] like Fig.12 As shown, the user enters the corresponding configuration interface by clicking the "Device Type" option, and reselects the type of HVAC equipment 500 in the configuration interface. According to the HVAC equipment 500 in the user's home, the user needs to select air conditioning (fluorine machine) and floor heating (valve type). The corresponding main screen interface will generate shortcut controls corresponding to air conditioning (fluorine machine) and floor heating (valve type). The first screen is the control interface of air conditioning (fluorine machine), which is used to control Daikin MX duct machine (4-core) central air conditioning. The second screen is the control interface of floor heating (valve type), which is used to control floor heating.

[0184] After that, LTR-X1503 is used to monitor whether someone is approaching (for example, whether there is someone within 30 cm of the thermostat). If no person is detected for a specified period of time, the screen is turned off and the device is put into standby mode. After that, it is monitored in real time whether there is someone and whether the screen 14 is touched. In addition, the proximity sensor 132 in this embodiment also has light sensing capability to automatically adjust the brightness of the screen 14 according to the light intensity. LTR-X1503 is a sensor chip with light sensing capability.

[0185] After detecting that someone is there and / or the screen 14 receives a touch operation, the screen lights up and displays the main interface. Thereafter, the SSD201 chip of the main control module 135 reads the touch data through the IIC interface to determine the function control being touched, and then determines whether the control command generated based on the screen 14 is a first-class command or a second-class command (wherein if the function control being touched is a function control of the control interface of the first-class HVAC equipment 501, it is a first-class command, and if the function control being touched is a function control of the control interface of the second-class HVAC equipment 502, it is a second-class command). If it is detected that the user operates the shortcut control of the main interface, the corresponding HVAC equipment 500 is directly controlled to turn on / off. If it is detected that the user operates the control of the first screen, the auxiliary control module 3151 is adjusted to control the fresh air (485). If it is detected that the user operates the control of the second screen, the first relay component (RL4) in the output on-off module 32 is adjusted to operate the valve of the floor heating (valve type).

[0186] See also Figure 14-15 , the thermostat 100 provided in one embodiment of the utility model is specifically explained. The thermostat 100 is a variation of the thermostat 100 of the previous embodiment. In particular, relative to the thermostat 100 of the previous embodiment, in this embodiment of the utility model, the auxiliary control module 3151 is not integrated in the thermostat 100, but is electrically connected to the HVAC equipment 500, and the thermostat 100 and the auxiliary control module 3151 are connected by wire. For example, for the control of a protocol-type fluorine machine central air conditioner, the auxiliary control module 3151 can be directly set inside the indoor or outdoor unit of the protocol-type fluorine machine central air conditioner to provide data format conversion for the protocol-type fluorine machine central air conditioner. Through the intermediate medium of the auxiliary control module 3151, the thermostat 100 can easily control various brands / models of the first type of HVAC equipment 501.

[0187] Specifically, Fig.14 As shown, in this embodiment of the present invention, the thermostat 100 includes a main control module 135, an output on-off module 32 and a communication module 134. The communication module 134 is electrically connected to the main control module 135, and the main control module 135 communicates externally through the communication module 134. The output on-off module 32 can be controlled by the main control module 135 to switch between on and off states, and is used to control the second type of HVAC equipment 502.

[0188] The main control module 135 is used to receive various control commands; when receiving a first type of command, it sends a corresponding control signal to the auxiliary control module 3151; when receiving a second type of command, it adjusts the output on-off module 32 to control the second type of HVAC equipment 502.

[0189] The auxiliary control module 3151 is pre-set with a changeable data conversion standard and is interconnected with the first type of HVAC equipment 501 through a communication interface. It is used to perform format conversion according to the currently set data conversion standard after receiving the control signal, so as to convert the received control signal into a data format that can be recognized by the first type of HVAC equipment 501, and control the first type of HVAC equipment 501 based on the converted data.

[0190] Furthermore, the thermostat 100 provided in this embodiment integrates the auxiliary control module 3151 at the HVAC equipment end, so that the thermostat 100 only needs to send a conventional control signal to the HVAC equipment. It can also realize the dynamic change of data conversion standards. The thermostat 100 of this embodiment has a more relaxed design space because there is no need to layout the auxiliary control module 3151.

[0191] Furthermore, the thermostat 100 is internally integrated with a 485 communication circuit (for transmitting the control signal of the fresh air (485)) and / or an air conditioning bus (for transmitting the control signal of the air conditioner (fluorine machine)), which is electrically connected to the main control module 135 and connected to the auxiliary control module 3151 arranged at the end of the HVAC equipment 500, so as to serve as a bridge for the thermostat 100 to connect the HVAC equipment 500, and to receive the control signal sent by the main control module 135. When the control signal is a control signal for the air conditioner (fluorine machine), the control signal is transmitted to the auxiliary control module 3151 through the air conditioning bus, and when the control signal is a control signal for the fresh air (485), the control signal is converted into a 485 communication format by the 485 communication circuit and then sent to the auxiliary control module 3151.

[0192] In addition, if Fig.15 As shown, in order to further expand the types of HVAC equipment 500 supported by the thermostat 100, in this embodiment of the utility model, an infrared transmitting circuit is added, and the infrared transmitting circuit is electrically connected to the main control module 135, and is used to send the control signal of the main control module 135 in the form of an infrared signal to realize the control of the indoor cabinet and the wall-mounted unit.

[0193] During the implementation of this solution, it is necessary to control the distance and angle between the thermostat 100 and the air conditioner cabinet and the wall mounted unit so that the infrared signal between the two can be transmitted smoothly. The main control module 135 of the thermostat 100 integrates the infrared coding formats of multiple air conditioners in software. The user can select the brand and model of the air conditioner used at home through the host computer of the terminal 200 to complete the matching control of the infrared signal.

[0194] In some examples, the main control module 135 sends a 38K carrier signal to the cabinet air conditioner and the wall-mounted air conditioner through the infrared transmitting tube of the infrared transmitting circuit. There is an infrared receiving circuit inside the cabinet and the wall-mounted air conditioner. When the 38K carrier signal transmitted by the thermostat 100 is received, the infrared receiving circuit will convert the carrier signal into a square wave signal that can be recognized by the internal MU, decode it according to the coding format, and perform corresponding actions, such as power on / off, mode switching, wind speed adjustment, timing and other functions.

[0195] See also Fig.16 , a thermostat 100 provided in an embodiment of the present invention is specifically explained. The thermostat 100 is a variation of the thermostat 100 of the above embodiment. In particular, relative to the thermostat 100 of the previous embodiment, in this embodiment of the present invention, the auxiliary control module 3151 is not integrated in the thermostat 100, but is electrically connected to the HVAC equipment 500, and the thermostat 100 and the auxiliary control module 3151 are connected wirelessly to avoid communication wiring between the two.

[0196] Specifically, Fig.16As shown, in this embodiment of the present invention, the thermostat 100 includes a main control module 135, an output on-off module 32 and a communication module 134. The communication module 134 is electrically connected to the main control module 135, and the main control module 135 communicates externally through the communication module 134. The output on-off module 32 can be controlled by the main control module 135 to switch between on and off states, and is used to control the second type of HVAC equipment 502.

[0197] The main control module 135 is used to receive various control commands; when receiving the first type of command, the control communication module 134 sends a corresponding control signal to the auxiliary control module 3151 wirelessly; when receiving the second type of command, the output on-off module 32 is regulated to control the second type of HVAC equipment 502.

[0198] The auxiliary control module 3151 is pre-set with a changeable data conversion standard and is interconnected with the first type of HVAC equipment 501 through a communication interface. It is used to perform format conversion according to the currently set data conversion standard after receiving the control signal, so as to convert the received control signal into a data format that can be recognized by the first type of HVAC equipment 501, and control the first type of HVAC equipment 501 based on the converted data.

[0199] Furthermore, the thermostat 100 provided in this embodiment integrates the auxiliary control module 3151 at the HVAC equipment end, so that the thermostat 100 only needs to send a conventional control signal to the HVAC equipment, and can also realize the dynamic change of data conversion standards. The thermostat 100 of this embodiment has a more flexible installation space and a wider coverage because it does not require a wired connection with the HVAC equipment 500.

[0200] Furthermore, the auxiliary control module 3151 includes a protocol adapter unit and a protocol converter. The protocol converter is electrically connected to the protocol adapter unit via a 485 bus, and is used to receive the wireless control signal sent by the temperature controller 100, and convert the control signal into a 485 communication format and send it to the protocol adapter unit so that the protocol adapter unit can recognize it.

The protocol converter of the auxiliary control module 3151 can use a 485 to Bluetooth protocol converter, which can convert the 485 signal sent by the protocol adapter unit into a Bluetooth format and send it to the thermostat 100, and can also convert the Bluetooth signal sent by the thermostat 100 into a 485 format and send it to the protocol adapter unit.

[0202] like Figures 17 to 32The present invention also provides a thermostat 100, which can be used to implement a thermostat control method provided in the above embodiment. Figures 17 to 32 These illustrations illustrate the physical form of the thermostat 100, which is not only a concrete embodiment of a design concept, but also a physical carrier for realizing the control logic and hardware structure of the thermostat 100. On this basis, the following embodiments are intended to detail the specific design structure and hardware details of the thermostat. The thermostat 100 provided by these embodiments can be implemented alone or combined with the software and hardware logic in the above embodiments to form a fully functional and efficient thermostat system solution.

[0203] First of all, it is understandable that the thermostat will produce significant thermal effects during normal operation, which directly interferes with and affects the accurate measurement of ambient temperature and humidity by the internal detection elements, thereby affecting the credibility of the temperature and humidity detection data. In addition, under different operating conditions, the heat generated by the thermostat itself is not constant, but changes dynamically, which undoubtedly increases the difficulty of quantifying the interference of internal thermal effects on temperature and humidity detection. Therefore, how to effectively suppress the negative impact of the thermostat's own heating on temperature and humidity detection data has become a technical problem that needs to be solved urgently.

[0204] Based on this, the purpose of an embodiment of the present invention is to improve the problem of insufficient accuracy of existing thermostats in detecting ambient temperature and humidity. Figure 17-Figure 27 As shown, the utility model provides a thermostat 100, which is suitable for being installed on a wall. Specifically, the thermostat 100 includes a panel housing 11 and a first sensor 12, wherein the first sensor 12 is arranged inside the panel housing 11 and is used to detect temperature and / or humidity; Fig.26 As shown, the panel housing 11 has a first bottom wall 111, the distance between the first sensor 12 and the first bottom wall 111 is less than 5 mm, and the first bottom wall 111 is provided with an air vent 112 at a position corresponding to the first sensor 12; when the thermostat 100 is installed on a wall, the first bottom wall 111 is located at the bottom of the panel housing 11, and the air vent 112 is open downward. The thermostat 100 can be understood as a device that can perform a switch action in response to a user operation, or a device that can control other devices to perform a switch action in response to a user operation. In some exemplary embodiments, the thermostat 100 can be a wall switch, a thermostat, etc. The first sensor 12 can be understood as a temperature sensor, a humidity sensor, or a sensor that can detect both temperature and humidity.

[0205] The thermostat 100 provided by the utility model sets the first sensor 12 near the bottom of the panel housing 11, which is far away from the part with the highest heat generation and can avoid the movement path of heat, thereby reducing the influence of the heat generation of the thermostat 100 on the temperature and humidity detection. In addition, a vent hole 112 is provided within a distance of 5 mm below the first sensor 12, and the vent hole 112 runs through both sides of the panel housing 11, so that the temperature and humidity at the location of the first sensor 12 are closer to the ambient temperature and humidity, thereby improving the detection accuracy of the first sensor 12. In a preferred embodiment, the distance between the first sensor 12 and the first bottom wall 111 is 1.2 mm.

[0206] It is worth noting that the air vent 112 is open downward, which has the following beneficial effects: (1) Since heat has the physical property of moving upward, the temperature and humidity below the thermostat 100 are closer to the ambient temperature and humidity. The air vent 112 is open downward, which can facilitate the air below to enter the air vent 112, thereby improving the accuracy of temperature and humidity detection; (2) The air vent 112 is open downward, making it difficult for dust to fall into the air vent 112; (3) When multiple thermostats 100 are installed side by side, the air vent 112 will not be blocked by the thermostats 100 on the left and right sides.

[0207] Furthermore, if Figure 22-Figure 26 As shown, the panel housing 11 is provided with a control circuit board 13, and the first sensor 12 is electrically connected to the control circuit board 13; the panel housing 11 has a first side wall 113, and the distance between the first sensor 12 and the first side wall 113 is less than 3mm, so that the first sensor 12 is arranged at the corner of the panel housing 11. Since the part with the highest heat generation of the thermostat 100 is located in the center, the first sensor 12 is arranged at the corner of the panel housing 11 to be away from the part with the highest heat generation, reducing the influence of heat generation on the first sensor 12, so that the detection accuracy of the first sensor 12 is improved. Among them, the control circuit board 13 is a weak current circuit board, which can receive and process the electrical signal of the first sensor 12 to obtain temperature and humidity data. The first side wall 113 can be understood as the side wall on the left or right side of the panel housing 11. In a preferred embodiment, the distance between the first sensor 12 and the first side wall 113 is 1.4mm.

[0208] Furthermore, the position design of the first sensor 12 and the structural design of the air vent 112 will minimize the impact of the thermal effect generated inside the thermostat 100 during normal operation on the ambient temperature and humidity measurement. Combined with the temperature and humidity compensation scheme in the above embodiment, the accuracy of the temperature and humidity measurement data can be significantly improved.

[0209] Furthermore, if Fig.17 , Fig.18 and Fig.24As shown, the panel housing 11 is provided with a screen 14, and the screen 14 is electrically connected to the control circuit board 13; since the screen 14 generates a large amount of heat when it is lit, and the heat is mainly concentrated in the display area 141 of the screen 14, the display area 141 is Fig.17 and Fig.18 The area surrounded by the middle dashed line is to reduce the effect of the heating of the screen 14 on the first sensor 12. Fig.24 As shown, a plane parallel to the control circuit board 13 is used as a projection plane, and the display area 141 of the screen 14 is projected on the projection plane to form a first projection pattern 142 ( Fig.24 The first sensor 12 is projected on the projection plane to form a second projection pattern (not shown in the figure), and the first projection pattern 142 does not overlap with the second projection pattern, thereby reducing the heat generated by the display area 141 and being transferred to the first sensor 12. Furthermore, in addition to the screen 14, another source of heat generation for the thermostat 100 is the electronic components on the circuit board. In order to reduce the impact of the heat generated by the electronic components on the first sensor 12, in this embodiment, the control circuit board 13 is projected on the projection plane to form a third projection pattern (not shown in the figure), wherein the third projection pattern does not overlap with the second projection pattern, thereby reducing the heat generated by the control circuit board 13 and being transferred to the first sensor 12.

[0210] In some embodiments, Fig.19 and Fig.31 As shown, the thermostat 100 also includes a bottom shell 3, a power circuit board 31 is arranged inside the bottom shell 3, and the power circuit board 31 is connected to the control circuit board 13 through a pin 131 and a female 311; wherein the power circuit board 31 is connected to 220V strong electricity, and a power module is arranged on the power circuit board 31, and the power module includes a transformer 318, and the power module can convert strong electricity into weak electricity, thereby providing power for the control circuit board 13. In order to reduce the influence of the heat of the power circuit board 31 on the first sensor 12, in this embodiment, an isolation plate 5 is arranged between the power circuit board 31 and the control circuit board 13, and the isolation plate 5 is covered on the bottom shell 3, and the power circuit board 31 is contained between the bottom shell 3 and the isolation plate 5, so that the isolation plate 5 can isolate part of the heat of the power circuit board 31 inside the bottom shell 3, reduce the heat transfer to the panel housing 11, and reduce the influence of the power circuit board 31 on the detection accuracy of the first sensor 12. A mounting member 4 is arranged around the bottom shell 3, and the panel shell 11 is detachably connected to the mounting member 4. It is worth mentioning that the isolation plate 5 also has an electrical isolation function, so that when the panel shell 11 is removed, the power circuit board 31 will not be exposed to the outside, thereby reducing the risk of electric shock.

[0211] Further, the power circuit board 31 is projected on the projection plane to form a fourth projection pattern (not shown in the figure), and the fourth projection pattern does not overlap with the second projection pattern, thereby reducing the heat transfer from the power circuit board 31 to the first sensor 12. Further, as Fig.29 and Fig.30 As shown, the bottom shell 3 is surrounded by mounting parts 4, and the mounting parts 4 are metal sheet metal parts, which are fixed to the bottom shell 3 by clamping. Since the mounting parts 4 are installed close to the wall, the temperature of the mounting parts 4 is closer to the ambient temperature; the mounting parts 4 are projected on the projection plane to form a fifth projection figure (not shown in the figure), and the second projection figure is included in the fifth projection figure, so that the temperature detected by the first sensor 12 is closer to the ambient temperature.

[0212] In some embodiments, Figure 22-Figure 25 As shown, the first sensor 12 is electrically connected to the control circuit board 13 via a first flat cable 121 . The first flat cable 121 is bent so that the first sensor 12 can be disposed at a corner of the panel housing 11 .

Among them, the side of the first sensor 12 can be understood as being close to the first sensor 12 and arranged in parallel with the first sensor 12. In this embodiment, as Fig.23 and Fig.26 As shown, the first sensor 12 is arranged at the lower right corner of the panel housing 11, the right side of the first sensor 12 is close to the first side wall 113, the lower side is close to the first bottom wall 111, and a heat-insulating foam 151 is arranged on the upper side and the left side respectively, which is used to prevent the heat in the center of the panel housing 11 from being transferred to the first sensor 12, and the heat-insulating foam 151 can prevent part of the heat generated by the screen 14 from being transferred to the first sensor 12, so that the detection accuracy of the first sensor 12 is higher. The heat-insulating foam 151 is made of EVA die-cut material.

[0214] In some embodiments, Fig.26 and Fig. 27As shown, an isolation space 16 is provided between the middle shell 19 and the panel shell 11 at a position corresponding to the first sensor 12, and the first sensor 12 is accommodated in the isolation space 16, wherein the isolation space 16 can be understood as an accommodation space formed by the middle shell 19 and the panel shell 11, and the isolation space 16 can cover the first sensor 12 to reduce the heat transfer from the center of the panel shell 11 to the first sensor 12. Furthermore, the air vent 112 is connected to the isolation space 16, so that the temperature and humidity in the isolation space 16 are closer to the ambient temperature and humidity.

[0215] In a specific embodiment, if Fig. 20 , Fig. 27 and Fig.26 As shown, the panel housing 11 is provided with a first isolation rib 114, the middle housing 19 is provided with a second isolation rib 191, and the first isolation rib 114, the second isolation rib 191, the inner wall of the middle housing 19 and the inner wall of the panel housing 11 are mutually enclosed to form the isolation space 16. The first cable 121 extends from the outside of the isolation space 16 into the inside of the isolation space 16, and one end of the first cable 121 close to the first sensor 12 is pressed and bent by the second isolation rib 191. The first cable 121 is attached to the panel housing 11 at the position corresponding to the first sensor 12.

[0216] Furthermore, if Fig. 20 and Fig.26 As shown, the middle shell 19 is fixedly connected to the panel shell 11 by a plurality of connecting bolts 192, wherein one of the connecting bolts 192 is arranged at the position of the second isolation rib 191, thereby enhancing the connection stability at the position of the second isolation rib 191, so that the positional relationship between the first sensor 12, the isolation space 16 and the thermal insulation foam 151 is more stable. The panel shell 11 is embedded with a knurled nut column 115 adapted to the connecting bolt 192 at the corresponding position of each connecting bolt 192. Before the panel shell 11 is injection molded, the knurled nut column 115 is first placed in the mold of the panel shell 11, and then the panel shell 11 is injection molded, so that the knurled nut column 115 is connected to the panel shell 11 as a whole.

[0217] Furthermore, if Fig. 20 and Fig.19 As shown, the middle shell 19 is constructed as a quadrilateral, and the four corners of the middle shell 19 are fixedly connected to the panel housing 11 by connecting bolts 192. Fig. 20 and Fig.23As shown, snap-fit ​​positions 193 are provided on both sides of the middle shell 19, and snap-fit ​​buckles 116 are provided on both sides of the panel shell 11. When the middle shell 19 is installed on the panel shell 11, the snap-fit ​​buckles 116 are first snapped into the snap-fit ​​positions 193 to pre-fix the middle shell 19 and the panel shell 11, and then the two are finally fixed by the connecting bolts 192.

[0218] The control circuit board 13 is provided with a pin header 131 on one side facing the bottom shell 3 , and the middle shell 19 is provided with a pin header through hole 194 at a position corresponding to the pin header 131 .

The transparent cover plate 17 is attached to the panel housing 11 by double-sided adhesive, and the screen 14 is clamped between the transparent cover plate 17 and the mounting groove 117. The bottom of the mounting groove 117 is provided with four square holes, and each square hole is provided with a conductive foam 152, one end of the conductive foam 152 is in contact with the lower surface of the screen 14, and the other end is in contact with the upper surface of the control circuit board 13, which is used to conduct the static electricity on the screen 14 to the control circuit board 13 to prevent the screen 14 from being damaged by static electricity. In a preferred embodiment, the screen 14 is set as an LCD touch screen (for details, please refer to the relevant records of the above embodiment for understanding).

[0220] like Fig. 22 and Fig.18 As shown, the screen 14 is provided with a second cable 143, and the second cable 143 passes through the panel housing 11 and is connected to the control circuit board 13. The upper end of the control circuit board 13 is electrically connected to a proximity sensor 132 and two microphones 133, and the two microphones 133 are respectively located on both sides of the proximity sensor 132. Fig.18 As shown, the proximity sensor 132 is arranged on the side of the panel housing 11 away from the control circuit board 13, and the proximity sensor 132 is clamped between the transparent cover 17 and the panel housing 11. The proximity sensor 132 is connected to the control circuit board 13 through the third cable 1321, and the third cable 1321 passes through the panel housing 11. The proximity sensor 132 adopts a sensor model LTR-X1503, which integrates light intensity detection and proximity sensing functions, can emit infrared light of a specified wavelength to the outside, and detect whether an object is close to the thermostat 100 based on the infrared light reflection principle. When the distance between the object and the thermostat 100 is less than a preset distance, the thermostat 100 controls the screen 14 to light up or switch the display content. Fig. 22 As shown, the microphones 133 are disposed below the top wall of the panel housing 11 , and sound guide holes 118 are formed through the top wall of the panel housing 11 at positions directly opposite to the microphones 133 .

[0221] like Fig. 22 and Fig.23 As shown, the control circuit board 13 is provided with a main control module 135 and a communication module 134. The main control module 135 is electrically connected to the screen 14, the proximity sensor 132, the first sensor 12, and the communication module 134. The main control module 135 can receive electrical signals from the proximity sensor 132, the first sensor 12, the communication module 134, and the screen 14, and the main control module 135 can control the screen 14 to display content and control the communication module 134 to send signals to the outside. The communication module 134 integrates Bluetooth and WIFI communication capabilities (2.4G). The communication module 134 is electrically connected to a patch antenna 1341, and the patch antenna 1341 is attached to the side wall of the panel housing 11 to prevent the signal of the communication module 134 from being shielded by the screen 14 and the control circuit board 13.

[0222] In some embodiments, Fig.26 As shown, the diameter of the vent hole 112 is greater than 2 mm, so that the air outside the panel housing 11 can enter the vent hole 112, thereby improving the detection accuracy of the first sensor 12. In a specific embodiment, the vent hole 112 is configured as a tapered hole with a small top and a large bottom, and the diameter of the upper end is 3 mm and the diameter of the lower end is 3.1 mm.

[0223] like Fig.19 As shown, the bottom shell 3 is surrounded by a metal mounting member 4, which is fixedly connected to the bottom shell 3 and fixedly connected to the dark box 6 by long screws. Since the mounting member 4 has low rigidity, it is easy to deform under the action of the locking force of the long bolt 451, and the bottom shell 3 will deform along with the mounting member 4, resulting in a change in the position of the power circuit board 31 inside the bottom shell 3. Since the power circuit board 31 is connected to the control circuit board 13 through the pin header 131 and the female header 311, a change in the position of the power circuit board 31 will cause a connection failure with the control circuit board 13. In order to solve the problem of easy deformation of the sheet metal and the bottom shell 3, in some embodiments, such as Fig.19 , Figure 28-Figure 30As shown, the thermostat 100 includes a panel assembly 1, a bottom shell 3, and a mounting member 4 arranged around the bottom shell 3, wherein the mounting member 4 is formed separately from the bottom shell 3; wherein the mounting member 4 is provided with a mounting portion 41, and the mounting portion 41 is configured to be connected to the dark box 6 through a threaded connector 45, and the bottom shell 3 is provided with a support portion 33 at a position corresponding to the mounting portion 41, and the support portion 33 is supported on a second surface of the mounting portion 41, and the second surface is configured as a side of the mounting portion 41 away from the panel assembly 1.

The threaded connector 45 can be understood as a connector with threads, and in a preferred embodiment, the threaded connector 45 is a long bolt 451. The mounting portion 41 is provided with a through hole, so that the threaded connector 45 can pass through the mounting portion 41 and be connected to the dark box 6.

[0224] like Fig.30 As shown, the dark box 6 is constructed as a box structure with one end open, and the temperature controller 100 is placed in the dark box 6 from the open end of the dark box 6. The left and right sides of the dark box 6 are respectively provided with connecting ears 61 inwardly, and the connecting ears 61 are provided with threaded holes. The threaded connector 45 passes through the mounting portion 41 and is connected to the threaded holes, thereby fixing the mounting member 4 to the dark box 6. When the locking force of the threaded connector 45 is large, the mounting portion 41 will deform toward the connecting ear 61, thereby causing the entire mounting member 4 to deform. In this embodiment, the bottom shell 3 of the thermostat 100 is provided with a supporting portion 33 at the position where the mounting portion 41 is located, and the supporting portion 33 is supported on the second surface of the mounting portion 41, and the second surface is the side of the mounting portion 41 facing the connecting ear 61. When the locking force of the threaded connection 45 is relatively large, the support portion 33 abuts against the second surface of the mounting portion 41. At this time, the bottom shell 3 and the mounting portion 4 jointly resist the deformation of the mounting portion 41, which greatly improves the anti-deformation ability of the mounting portion 41 and reduces the deformation of the mounting portion 4 and the bottom shell 3, thereby avoiding failure of the connection between the power circuit board 31 and the control circuit board 13.

[0225] like Fig.28 and Fig.29 As shown, the support portion 33 may be a buckle, a support rib or other structures. In a specific embodiment, the support portion 33 is configured as a support buckle, and the support buckle is integrally formed with the bottom shell 3. It is worth mentioning that the support portion 33 uses a support buckle so that the mounting member 4 can be sleeved on the bottom shell 3 from the bottom of the bottom shell 3. In a specific embodiment, as Fig.28 and Fig.29As shown, the bottom shell 3 is circumferentially arranged with a plurality of abutting portions 34 and a plurality of limiting buckles 35, the mounting member 4 is sleeved on the bottom shell 3 from bottom to top, the abutting portion 34 abuts against the upper side of the mounting member 4, and the limiting buckle 35 is clamped on the lower side of the mounting member 4, so as to limit the mounting member 4. In a specific embodiment, the abutting portion 34 and the limiting buckle 35 are integrally formed on the bottom shell 3, the abutting portion 34 is constructed as a rib protruding outward from the side of the bottom shell 3, the mounting member 4 is provided with an abutting interface 42 at a position corresponding to the abutting portion 34, the abutting portion 34 is embedded in the abutting interface 42, so that the upper surface of the mounting member 4 is flush with or higher than the upper surface of the bottom shell 3, so that the mounting member can be magnetically connected to the panel assembly 1.

[0226] In some embodiments, Figure 28-Figure 30 As shown, the mounting parts 41 are respectively provided on both sides of the mounting member 4, and the mounting parts 41 are provided with mounting holes 411, and the threaded connector 45 is connected to the outside through the mounting holes 411; the mounting member 4 has a first surface facing the panel assembly 1, and the mounting part 41 is recessed in the first surface, and the recess amount is less than 3mm. The purpose of the mounting part 41 being recessed in the first surface is to accommodate the nut of the threaded connector 45, so that the space of the panel assembly 1 occupied by the nut is smaller, thereby reducing the thickness of the panel assembly 1. It is worth noting that in this embodiment, the recess amount of the mounting part 41 is controlled to be less than 3mm to avoid interference between the mounting part 41 and the connecting ear 61 of the dark box 6.

[0227] It is worth noting that the mounting member 4 and the bottom shell 3 are formed separately, which is conducive to the mounting member 4 and the bottom shell 3 being made of different materials. In some embodiments, the mounting member 4 is made of iron material, and the panel assembly 1 includes a permanent magnet 18. The panel assembly 1 is magnetically connected to the mounting member 4 through the permanent magnet 18 to achieve rapid disassembly and assembly between the panel assembly 1 and the bottom shell 3.

[0228] Furthermore, the mounting member 4 is formed by stamping an iron sheet metal part, and the mounting portion 41 is integrally formed on the mounting member 4 .

[0229] Furthermore, if Fig.19As shown, there are multiple permanent magnets 18, all of which are arranged at the first end of the panel assembly 1. The panel assembly 1 has a second end away from the first end, and the second end is provided with a snap-in position 1191. One end of the mounting member 4 is snap-into the snap-in position 1191, and the other end is magnetically connected to the permanent magnet 18. In a specific embodiment, the mounting member 4 is provided with a plug tongue 43 adapted to the snap-in position 1191 at a position corresponding to the snap-in position 1191, and the plug tongue 43 is tilted toward the panel assembly 1, and the plug tongue 43 is inserted into the snap-in position 1191 to achieve snap-in connection between the plug tongue 43 and the snap-in position 1191. The mounting member 4 is provided with a suction portion 44 at a position corresponding to the permanent magnet 18, and the suction portion 44 is integrally formed with the mounting member 4. When the panel assembly 1 is installed on the mounting member 4, firstly, the second end is brought close to the plug tongue 43 so that the plug tongue 43 is inserted into the snap-fit ​​position 1191, and then the first end is brought close to the suction portion 44 so that the suction portion 44 is sucked into the permanent magnet 18, and the installation is completed; when the panel assembly 1 is disassembled from the mounting member 4, firstly, the first end of the panel assembly 1 is opened outward so that the suction portion 44 is disengaged from the permanent magnet 18, and then the second end is moved until the plug tongue 43 is disengaged from the snap-fit ​​position 1191, and the disassembly is completed. Compared with the traditional snap-fit ​​connection, the panel assembly 1 of this embodiment adopts a connection method in which one end is snapped and the other end is magnetically attracted, so that the panel assembly 1 and the bottom shell 3 can be installed and disassembled more quickly and conveniently.

[0230] Furthermore, if Fig.21 and Fig. 20 As shown, a magnet limiting groove 1192 is downwardly provided on the top wall of the panel shell 11, and the size of the magnet limiting groove 1192 is adapted to the permanent magnet 18. The magnet limiting groove 1192 is open downward, and the permanent magnet 18 is loaded from the bottom of the magnet limiting groove 1192; two limiting ribs 1193 are provided on the side of the magnet limiting groove 1192 facing the bottom shell 3, and the limiting ribs 1193 abut against the side of the permanent magnet 18 facing the bottom shell 3, and can block the permanent magnet 18 from moving toward the bottom shell 3; the middle shell 19 is provided with a magnet accommodating groove 195 at a position corresponding to the magnet limiting groove 1192, and when the middle shell 19 is buckled into the panel shell 11, the magnet accommodating groove 195 encompasses the magnet limiting groove 1192, and the magnet accommodating groove 195 abuts against the lower surface of the permanent magnet 18, and the permanent magnet 18 is limited in the magnet limiting groove 1192. The two limiting ribs 1193 are respectively located on the left and right sides of the permanent magnet 18 . When the permanent magnet 18 is attracted to the attracting portion 44 of the mounting member 4 , the attracting portion 44 is located between the two limiting ribs 1193 .

[0231] Furthermore, if Fig.29 and Fig.31As shown, an isolation plate 5 is provided between the power circuit board 31 and the control circuit board 13, the isolation plate 5 is fixedly connected to the bottom shell 3, and the side of the isolation plate 5 abuts against the inner wall of the bottom shell 3, and the power circuit board 31 is clamped between the isolation plate 5 and the bottom shell 3. Among them, since the isolation plate 5 is fixedly connected to the bottom shell 3, and the side of the isolation plate 5 abuts against the inner wall of the bottom shell 3, the isolation plate 5 has a reinforcing effect on the rigidity of the bottom shell 3, so that the bottom shell 3 is not easy to deform, and the position of the power circuit board 31 inside the bottom shell 3 is prevented from changing greatly; and since the power circuit board 31 is clamped between the isolation plate 5 and the bottom shell 3, the position of the power circuit board 31 is more stable.

[0232] In a specific embodiment, if Fig.31 As shown, the bottom shell 3 is constructed as a box structure with an open top, the isolation plate 5 is covered on the open side of the bottom shell 3, and three connecting columns 36 are extended upward from the bottom shell 3. The isolation plate 5 is fixedly connected to the connecting columns 36 by self-tapping screws 51. The power circuit board 31 is provided with through holes at positions corresponding to the self-tapping screws 51, and the self-tapping screws 51 are connected to the connecting columns 36 through the through holes. A female header 311 is provided on one side of the power circuit board 31 facing the panel assembly 1, and a female header through hole 52 is provided on the isolation plate 5 at positions corresponding to the female header 311, and the female header 311 is exposed to the upper surface of the isolation plate 5 through the female header through hole 52.

[0233] Common air conditioners used in home decoration now include protocol-type fluorine machine central air conditioners (hereinafter referred to as fluorine machine air conditioners) and fan coil central air conditioners. In some embodiments, the thermostat 100 can control the operation of the fan coil central air conditioner. The fan coil central air conditioner generally includes an air conditioner host, a water pump, an air conditioning water valve, a water flow pipeline and a fan coil. The air conditioner host is used to heat or cool water, and the water pump is used to drive the water to circulate, so that the heated or cooled water flows through the water flow pipeline, the air conditioning water valve, the fan coil, and finally flows back to the air conditioner host. The air conditioning water valve is used to control the water flow in the fan coil. The fan coil blows the heat or cold carried in the water into the room, so that the indoor temperature increases or decreases. The thermostat 100 provided by the utility model can be connected to a fan coil central air conditioner. The thermostat 100 controls the switch of the air conditioning water valve and the air volume of the fan coil to achieve the purpose of controlling the room temperature. In a specific embodiment, such as Fig.32This is a perspective after the power circuit board 31 is flipped upside down. The bottom of the power circuit board 31 is provided with a wiring terminal 312, three single-pole single-throw relays 313 and a single-pole double-throw relay 314. The wiring terminal 312 has seven wiring holes, wherein the first wiring hole and the second wiring hole are respectively connected to the neutral wire and the live wire; the third wiring hole is connected to the high wind speed gear port of the fan coil unit, the fourth wiring hole is connected to the medium wind speed gear port of the fan coil unit, and the fifth wiring hole is connected to the low wind speed gear port of the fan coil unit. The three single-pole single-throw relays 313 are respectively electrically connected to the third wiring hole, the fourth wiring hole and the fifth wiring hole, and are used to control the fan coil unit to switch between high, medium and low gears; the sixth wiring hole is connected to the closing port of the air-conditioning water valve, and the seventh wiring hole is connected to the opening port of the air-conditioning water valve. The single-pole double-throw relay 314 is electrically connected to the sixth wiring hole and the seventh wiring hole, and is used to control the opening and closing of the air-conditioning water valve.

[0234] It is worth noting that the thermostat 100 provided in this embodiment can only control the switch of the air conditioning water valve and the air volume of the fan coil. When the air conditioner needs to switch the cooling / heating mode, the user needs to operate the air conditioning host to switch. Since the thermostat 100 of this embodiment only includes one single-pole double-throw relay 314, it can only control one air conditioning water valve, so this embodiment is suitable for a two-pipe fan coil central air conditioner; in other embodiments, if two single-pole double-throw relays 314 are provided on the power circuit board 31, the thermostat 100 can control two air conditioning water valves, which can be suitable for a four-pipe fan coil central air conditioner.

[0235] In some embodiments, the thermostat 100 can control the operation of floor heating and fresh air blower. In a specific embodiment, Fig.32 As shown, a wiring terminal 312, three single-pole single-throw relays 313 and a single-pole double-throw relay 314 are provided at the bottom of the power supply circuit board 31, and the wiring terminal 312 has seven wiring holes, wherein the first wiring hole and the second wiring hole are respectively connected to the neutral wire and the live wire; the third wiring hole is connected to the high wind speed gear port of the fresh air fan, the fourth wiring hole is connected to the medium wind speed gear port of the fresh air fan, and the fifth wiring hole is connected to the low wind speed gear port of the fresh air fan, and the three single-pole single-throw relays 313 are respectively electrically connected to the third wiring hole, the fourth wiring hole and the fifth wiring hole, for controlling the fresh air fan to switch between high, medium and low gears; the sixth wiring hole is connected to the closing port of the floor heating water valve, and the seventh wiring hole is connected to the opening port of the floor heating water valve, and the single-pole double-throw relay 314 is electrically connected to the sixth wiring hole and the seventh wiring hole, for controlling the opening and closing of the floor heating water valve.

[0236] Existing fluorine air conditioners are provided with a control port, which is connected to a central controller. The central controller issues control commands to control the operation of the fluorine air conditioner. Since different brands of fluorine air conditioners have different data conversion standards, existing thermostats are difficult to adapt to multiple brands of fluorine air conditioners. In addition, control commands are transmitted via weak current, and existing thermostats generally set the weak current board in the panel housing and the strong current board in the bottom housing. Since the thermostat needs to be wired inside the dark box, the weak current board cannot be directly connected to the communication wire, which brings inconvenience to the wiring. In order to enable the thermostat 100 provided by the utility model to control fluorine air conditioners of various brands and facilitate the connection of communication wires, in some embodiments, such as Fig.32 As shown, the power circuit board 31 and the communication circuit board 315 are arranged inside the bottom shell 3, and the communication circuit board 315 is electrically connected to the power circuit board 31, and the power circuit board 31 carries a strong current circuit (strong current power conversion circuit, relay, etc.), and the communication circuit board 315 carries a weak current circuit; the communication circuit board 315 can switch the data conversion standard, and is configured to be able to output a control signal to the outside, and this function can be provided by an auxiliary control module 3151 arranged on the communication circuit board 315. As for the specific implementation method, it has been introduced in detail in the above embodiment, and will not be repeated here. A strong current power conversion circuit is arranged on the power circuit board 31, which can convert strong electricity into weak electricity, thereby providing electrical energy for the communication circuit board 315.

[0237] And thanks to the fact that the communication circuit board 315 is arranged on the power circuit board 31, the communication circuit board 315 is located in the bottom shell 3, so that the communication wires of the controlled device can be more directly and conveniently connected to the communication circuit board 315. It can be understood that if the communication circuit board 315 is arranged on the control circuit board 13, the communication circuit board 315 will not only occupy the space of the panel assembly 1, but also be inconvenient to connect the communication wires.

[0238] In addition, it is worth noting that the assembly and electrical connection method of the communication circuit board 315 is applicable to the scenario in which the auxiliary control module 3151 is integrated into the thermostat 100 in the above embodiment. However, the communication circuit board 315 is not limited to the above installation method. For example, in the above embodiment, in the scenario where the auxiliary control module 3151 needs to be integrated into the HVAC equipment 500, the communication circuit board 315 carrying the auxiliary control module 3151 can be installed in the HVAC equipment 500 and powered by the corresponding circuit.

[0239] Furthermore, if Fig.32As shown, in one embodiment, the communication circuit board 315 is welded to the power circuit board 31; the power circuit board 31 is provided with a communication terminal 316, the communication terminal 316 is used to connect to the controlled device, the communication terminal 316 is electrically connected to the communication circuit board 315 via the power circuit board 31, so that the communication circuit board 315 will not be loosened due to wiring with the power circuit board 31, and the communication circuit board 315 outputs a control signal to the outside through the communication terminal 316. The controlled device includes a fluorine machine air conditioner and a fresh air blower, and the communication circuit board 315 can simultaneously control the operation of the fluorine machine air conditioner and the fresh air blower. Further, the communication circuit board 315 and the communication terminal 316 are both arranged on the lower surface of the power circuit board 31, and the communication terminal 316 is provided with a plurality of connection holes for connecting the communication wires of the controlled device, and the bottom shell 3 is provided with a wiring through hole at the corresponding position of each connection hole, and the communication wire passes through the wiring through hole and is connected to the connection hole. Further, the communication terminal 316 and the connection terminal 312 are respectively arranged at both ends of the power circuit board 31. The communication terminal 316 is arranged at a corner of the power circuit board 31 , and the bottom shell 3 is provided with three connecting posts 36 , which are respectively located at the corners of the power circuit board 31 . The bottom shell 3 does not have the connecting post 36 near the communication terminal 316 .

[0240] Furthermore, if Fig.32 As shown, the communication circuit board 315 is vertically soldered to the power circuit board 31 to facilitate heat dissipation of the communication circuit board 315 .

[0241] Furthermore, if Fig.32 As shown, the communication circuit board 315 is provided with a second communication module, and the second communication module can communicate wirelessly with the outside. The communication circuit board 315 switches the data conversion standard based on the signal input of the second communication module, so that the communication circuit board 315 can independently connect to the terminal in a wireless communication manner, and the user can wirelessly control the communication circuit board 315 to switch the data conversion standard through the terminal, thereby improving the convenience of operation. In one embodiment, the second communication module is a Bluetooth communication module, and the user can select the brand and model of the controlled device through the mobile phone APP, and transmit the controlled device information to the second communication module through Bluetooth communication. The communication circuit board 315 switches the data conversion standard to a data conversion standard compatible with the controlled device model based on the controlled device information received by the second communication module. Furthermore, the communication circuit board 315 is provided with an onboard antenna 317, and the onboard antenna 317 is electrically connected to the second communication module for the second communication module to send and receive signals.
