Please refer to Figure 1 An embodiment of the utility model provides a kind of control system, which can include temperature controller 100, the temperature controller 100 is used to connect heating equipment 500 and control these heating equipment 500.In part scheme, the control system further includes terminal 200 and gateway 400.

[0063] The terminal 200 therein can be understood as any device or combination of devices with data processing capability and external communication capability, for example, it can be as Figure 2 Mobile phone 201, of course, in addition to mobile phone 201, terminal 200 can also be other, for example, computer, car machine, smart watch, smart VR device, etc., and the embodiment is not limited. The gateway 400 therein can be understood as any network gateway 400, which can be, for example, any one of WIFI network (router 401), ZIGBEE network, Bluetooth network (Bluetooth gateway 402);In the following description, it is mainly described based on WIFI communication mode.

[0064] Further scheme, gateway 400 can access the Internet, so as to realize data exchange with other devices (for example, terminal 200, other external devices 600) accessing the Internet.In addition, gateway 400 can be a gateway device (for example, router 401, Bluetooth gateway 402) dedicated to gateway, or other devices with gateway function, such as sound box with gateway function, display device with gateway function, wall switch with gateway function, etc.

[0065] In part scheme, the control system can also include server 300, gateway 400 and terminal 200 can interact with server 300, and the data interaction between gateway 400 and terminal 200 can be realized based on server 300.In part example, server 300 can be cloud 301 (cloud server), which can play the role of data storage and processing.

[0066] In one embodiment, such as Figure 2 As shown, gateway 400 is a Wi-Fi gateway (i.e., router 401), and the corresponding network is a Wi-Fi network. Thermostat 100 can join the Wi-Fi network after network configuration and access the Internet through router 401, thereby communicating with cloud 301. Terminal 200 is mobile phone 201, which can access cloud 301 via cellular data, wireless LAN, etc. Other external devices 600 (such as temperature and humidity sensors) can also access cloud 301 through their corresponding Bluetooth gateway 402 or router 401. Therefore, communication between thermostat 100 and mobile phone 201, and between thermostat 100 and other external devices 600 connected to cloud 301, can all be achieved through cloud 301 as an intermediary.

[0067] The HVAC equipment 500, namely heating, ventilation, and air conditioning equipment, is used to create an indoor environment to meet users' comfort requirements for temperature, humidity, air quality, etc. There are various types of HVAC equipment 500; 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 conditioning, underfloor heating, valve-type fresh air systems, etc.) and protocol-type HVAC equipment (i.e., HVAC equipment controlled by signals, such as protocol-type refrigerant central air conditioning, 485 fresh air units, etc.). The thermostat 100 can control these HVAC devices in various ways, including but not limited to: controlling entry into a certain state, such as turning the air conditioner on or off, turning the underfloor heating on or off, or turning the fresh air system on or off; controlling switching between multiple states, such as switching the cooling and heating modes of the air conditioner, switching the on and off modes of the fresh air system, and switching the on and off modes of the underfloor heating; and controlling changes in operating parameters, such as adjusting the cooling / heating temperature of the air conditioner, adjusting the fan speed of the fresh air system, and adjusting the temperature of the underfloor heating, etc. For valve-type HVAC devices, control is achieved by controlling the action of their valves; for protocol-type HVAC devices, control is achieved by sending corresponding communication signals. Depending on the type of HVAC device 500 connected to the thermostat 100, the specific content of the control and the controlled device can be arbitrarily varied, without departing from the scope of this utility model embodiment. Furthermore, the following description of the thermostat 100's control over the HVAC device 500 can also be understood with reference to the above content.

[0068] The existing heating equipment can usually only rely on the exclusive control panel provided by each manufacturer to realize the management of the equipment. This dependence not only limits the user's selection freedom, but also reduces the overall integration and operation convenience of the smart home system, because it means that the user has to frequently switch between multiple different control interfaces when multiple heating equipment are installed in the home, and cannot enjoy a unified and smooth control experience. In addition, in the field of controlling protocol-type heating equipment, the data communication standards adopted by various suppliers show significant diversity. Even between different brands or different models of equipment of the same supplier, there may be significant differences in data conversion protocols, which also increases the difficulty of managing these heating equipment through one temperature controller. Therefore, it is crucial to seek a smart temperature controller solution that can uniformly manage multiple types of heating equipment and be compatible with various data conversion standards to improve the device versatility and user interaction experience.

[0069] Based on this, the utility model provides a kind of temperature controller control method, this control method gives temperature controller 100 strong compatibility, makes it not only can control valve type and protocol type two categories of heating equipment across domain, and it is realized to the intelligent adaptation of protocol type heating equipment model.

[0070] The following will be expanded to describe the various embodiments of the control method provided by the utility model, and in addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as there is no conflict between them.

[0071] Referring to Figure 3 , a control method of a temperature controller is provided, which can be applied to the temperature controller 100 in the above control system. The temperature controller 100 supports multiple types of heating equipment 500, including at least the first type of heating equipment 501 and the second type of heating equipment 502. As mentioned above, the first type of heating equipment 501 can be, for example, a protocol-type heating equipment, and the second type of heating equipment 502 can be, for example, a valve-type heating equipment, and the control methods of the two are different.

[0072] According to Figure 3 It can be seen that the control method at least includes steps S1-S3. Among them:

[0073] S1, receive control commands. The controlled mode of the temperature controller 100 is various, such as terminal direct connection control, cloud control, local control, etc. Further, the control command can also have various sources, such as receiving the control command from the terminal 200 (mobile phone APP, smart sound box) through WIFI, Bluetooth communication mode, and receiving the control command input by the user in the local interface of the temperature controller 100. According to the type of the controlled heating and ventilation equipment pointed by the control command, the embodiment divides the control command into various types (such as the first type of command and the second type of command involved in the subsequent embodiment), which is used to control each type of heating and ventilation equipment 500.

[0074] S2, when receiving the first type of command, send the corresponding control signal to the auxiliary control module 3151; the auxiliary control module 3151 internally presets 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 the first type of heating and ventilation equipment 501 can recognize, and based on the converted data, control the first type of heating and ventilation equipment 501, so as to realize the control of them.

[0075] S3, when receiving the second type of command, regulate the output on-off module 32 to control the second type of heating and ventilation equipment 502.

[0076] Specifically, in the process of using the temperature controller 100, the user needs to set the data conversion standard in the auxiliary control module 3151 according to the first type of heating and ventilation equipment 501 connected to the temperature controller 100, so that when receiving the first type of command, the data format converted by the auxiliary control module 3151 is successfully recognized by the heating and ventilation equipment 500.

[0077] When the user controls the temperature controller 100 through various ways, if the control command is the first type of command for the first type of heating and ventilation equipment 501, the temperature controller 100 sends the corresponding control signal to the auxiliary control module 3151, and the auxiliary control module 3151 will convert the control signal into a format that the first type of heating and ventilation equipment 501 can recognize according to the preset data conversion standard, and send it to the corresponding equipment, to realize the control of the first type of heating and ventilation equipment 501. If the control command is the second type of command for the second type of heating and ventilation equipment 502, the temperature controller 100 regulates the output on-off module 32 to directly control the second type of heating and ventilation equipment 502.

[0078] According to the control method provided in the embodiment, the temperature controller 100 can support multiple types of heating and ventilation equipment 500, and when multiple types of heating and ventilation equipment 500 are installed in a user's home, it is no longer necessary to specially set up a control panel for each type of heating and ventilation equipment 500. The method provided in the embodiment makes the temperature controller 100 a universal temperature controller, which can replace the temperature control device configured by the heating and ventilation equipment itself, and can provide intelligent control for the heating and ventilation equipment. For example, when a user purchases a fluorine machine central air conditioner, the temperature controller 100 can directly replace the control panel originally carried by the fluorine machine central air conditioner, and provide networking capabilities for the fluorine machine central air conditioner.

[0079] Furthermore, the innovative design of the temperature controller control method provided in the embodiment not only gives the temperature controller unprecedented strong compatibility and flexibility, but also realizes dynamic change of the data conversion standard built in the auxiliary control module 3151 in the protocol type heating and ventilation equipment control, thereby achieving accurate "on-demand adaptation" and providing users with more extensive choices to meet different use requirements.

[0080] Further, the data conversion standard currently set by the auxiliary control module 3151 is set after selecting from multiple preset data conversion standards; each data conversion standard corresponds to a specific first type of heating and ventilation equipment 501. Specifically, multiple selectable data conversion standards are pre-configured, each data conversion standard corresponds to a first type of heating and ventilation equipment 501 of a certain supplier or a sub-category (brand and / or model) of the supplier, and the specific content of the data conversion standard of the equipment of the supplier can be obtained by negotiation with the supplier, and then configured as a selectable data conversion standard, so that the equipment of the supplier is supported. The pre-configuration here can be understood as pre-storing multiple data conversion standards in the cloud or locally in the auxiliary control module 3151, and selecting from multiple preset data conversion standards, or it can be understood as selecting locally or through a terminal.

[0081] Furthermore, the user can select a matching data conversion standard for the auxiliary control module 3151 according to the first type of heating and ventilation equipment actually connected to the temperature controller 100, realize dynamic adjustment of the specific model of the protocol type heating and ventilation equipment that the temperature controller 100 can support, and make the temperature controller have high configurability and dynamic adaptability, thereby better meeting the diversified needs of users.

[0082] A feasible way to set the data conversion standard is given below:

[0083] The auxiliary control module 3151 receives a specific configuration command and adjusts the data conversion standard stored therein according to the configuration command; after the configuration is completed, the auxiliary control module 3151 will convert the control signal according to the set data conversion standard during normal operation.

[0084] The configuration command can be generated in two ways: the first way is that the user selects from a plurality of preset data conversion standards; the second way is that the auxiliary control module 3151 successfully connects the first type of heating and ventilation equipment 501, and then automatically downloads the configuration command from the cloud according to the identified equipment brand and / or model.

[0085] When the configuration command is generated in the first way, the control method further comprises: 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 the user selects one of a plurality of selectable setting items displayed on the terminal 200; each setting item represents a selectable data conversion standard.

[0086] The configuration instruction can be sent directly to the auxiliary control module 3151, or indirectly, such as through the cloud, a gateway, or first to the main control module 135 and then sent to the auxiliary control module 3151 by the main control module.

[0087] Setting the data conversion standard based on the configuration instruction means that the pre-set data conversion standard is set / reset to match the target setting item selected by the user on the terminal according to the indication of the configuration instruction. For example, according to the configuration instruction, specify the corresponding data conversion standard in the plurality of data conversion standards stored locally as the set data conversion standard. For another example, according to the configuration instruction, download the corresponding data conversion standard from the specified address in the cloud, so as not to store a large amount of data locally, and without the need to modify the hardware, the product has stronger scalability.

[0088] 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 in the first case, the auxiliary control module 3151 establishes a connection with the host computer software of the mobile phone, which can be an application (APP) or a WeChat applet, an Alipay applet, etc. The user can select from a plurality of selectable setting items through the interactive interface of the host computer software to generate the configuration instruction. Each selectable setting item represents a selectable data standard, and the selectable setting item can be presented in various ways in the interactive interface, such as directly displaying the version number of the data conversion standard, based on which the user can identify and select the required data conversion standard. For another example, display the brands and / or models of a plurality of heating and ventilation equipment 500, and the user selects the actual connected heating and ventilation equipment 500 from the displayed plurality of heating and ventilation equipment 500.

[0089] Further example, the auxiliary control module 3151 uses Bluetooth technology for wireless communication, and the host computer software selects WeChat applet as the operation platform. The user searches and connects the Bluetooth of the auxiliary control module 3151 through the WeChat applet to realize direct wireless communication between them.

[0090] In a possible application scenario, the user wants to control a fluorine machine central air conditioner which adopts Modbus protocol format (i.e. data conversion standard). 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 WeChat applet. In actual use, the user inputs the desired temperature set value on the control interface of the temperature controller 100 to generate the first type of command. The main control module 135 of the temperature controller 100 sends the control signal corresponding to the command to the auxiliary control module 3151. 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 conditioning unit through wired or wireless mode, so that the air conditioning unit works accordingly.

[0091] In addition, the temperature controller 100 has a main control module 135 which has a wireless communication function and can remotely connect the user's smart terminal 200.

[0092] The control method further comprises: 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 the direct communication relationship between the terminal 200 and the auxiliary control module 3151, the user can directly send control commands to the auxiliary control module 3151 through the interface provided by the host computer software to control the first type of heating and ventilation 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 in the case that the wireless communication of the main control module 135 is not available, the user can still control the first type of heating and ventilation equipment 501 through the communication path with the auxiliary control module 3151.

[0093] Further, the output on-off module 32 includes a first relay assembly and a second relay assembly. When receiving the second type of command, the output on-off module 32 is regulated to control the second type of HVAC 502 connected thereto, specifically including: regulating the first relay assembly to control the valve of the fan-coil central air conditioner and / or the floor heating in the second type of HVAC 502; and / or, regulating the second relay assembly to control the fan of the valve fresh air system in the second type of HVAC 502. The first relay assembly can include one or more relays, and the same applies to the second relay assembly. Depending on the second type of HVAC 502 to be controlled, the type of relay can also be different. For example, the relay for controlling the high, medium and low gears of the fresh air system can be a single-pole single-throw relay, while the relay for controlling the floor heating or fan coil can be a single-pole double-throw relay. How the relay assemblies control the valves or fans of the second type of HVAC 502 will be described in detail in subsequent product embodiments of the present application, which will not be described here.

[0094] Further, according to this embodiment of the present application, the output on-off module 32 of the thermostat 100 includes two groups of relay assemblies, the first group being used to control the valves of the fan-coil central air conditioner and the water floor heating, and the second group being used to control the fan of the fresh air system; when receiving the second type of command, the thermostat 100 will regulate the two groups of relays respectively to achieve precise control of different types of second type of HVAC 502.

[0095] The types of HVAC that the existing thermostat can control are fixed, i.e., determined at the time of factory shipment and cannot be changed, which is not conducive to adapting to different types of HVAC in various use scenarios, resulting in poor product versatility and flexibility in applicable scenarios.

[0096] In addition, the control method of the existing thermostat or the thermostat itself has the type of HVAC that is pre-set at the time of factory shipment and cannot be adjusted according to subsequent changes, which constitutes a significant limitation in the face of diversified use scenarios, especially when different environments need to match different types of HVAC. Due to such fixity, the product is difficult to meet the broad application requirements, and its versatility and flexibility in adapting to complex scenarios are greatly compromised, reducing user satisfaction and ease of use in different situations. Based on this, an embodiment of the present application provides a thermostat control method, which gives the thermostat the ability to change the type of controlled HVAC at any time.

[0097] Specifically, the control method of the temperature controller further comprises S10-S30 before receiving the control command. Wherein: S10, receiving the user's selection of the type of heating and ventilation equipment 500. The selection may, for example, be a visual selection process local to the temperature controller 100, and the user interface of the temperature controller 100 provides selection options for the type of heating and ventilation equipment 500. The local visual selection process can to some extent avoid user misselection, resulting in a type of heating and ventilation equipment that does not match the actual connection of the temperature controller and cannot be controlled. In some examples, as shown in Figure 4 The optional types of heating and ventilation equipment 500 include but are not limited to air conditioners, floor heating, and fresh air, wherein the air conditioner is subdivided into fluorine machines (protocol type fluorine machine central air conditioner), valve type (fan coil central air conditioner), 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 the present embodiment, all valve type heating and ventilation equipment is classified as the second type of heating and ventilation equipment 502 (fan coil central air conditioner, valve type floor heating, valve type fresh air system), and all protocol type heating and ventilation equipment is classified as the first type of heating and ventilation equipment 501 (protocol type fluorine machine central air conditioner, protocol type fresh air system). S20, generating a corresponding control interface according to the selected target heating and ventilation equipment type. By means of user self-selection of the target equipment type, the control interface can be switched at any time according to the actual needs of the user. For example, during the use of the temperature controller 100, the temperature controller 100 receives the user's input of reselecting the target heating and ventilation equipment type, and the temperature controller 100 can dynamically switch to the corresponding control interface according to the user's reselection, thereby realizing that the target heating and ventilation equipment type of the temperature controller 100 can be changed at any time according to the user's needs. S30, displaying the generated control interface, and generating the first type of command and / or the second type of command through the operation of the interface to realize the operation of the first type of heating and ventilation equipment 501 and / or the second type of heating and ventilation equipment 502. Specifically, the user's operation on the control interface generates the first type of command which is transmitted to the auxiliary control module 3151 for execution, and the second type of command which is transmitted to the output on-off module 32 for execution. In some examples, the control that can be realized by the control interface may, for example, but not limited to, turning on / off, temperature setting, wind speed adjustment, mode switching, etc. Wherein, when the user selects multiple types of heating and ventilation equipment, separate control interfaces are generated, i.e. each control interface occupies one screen.

[0098] Further, the control method of the present embodiment provides visual device selection, automatically generates a corresponding control interface according to the user's selection of the type of heating and ventilation equipment, and the user can issue control commands based on the control interface, thereby improving the versatility and adaptability of the temperature controller 100 and realizing the dynamic change of the target heating and ventilation equipment type controlled by the temperature controller 100.

[0099] A possible application scenario is as follows: a 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 temperature controller, the user only needs to select the fresh air (485) and floor heating (valve type) device types on the corresponding device type configuration interface of the temperature controller 100, so as to generate the corresponding control interface. Then the user can switch the control interface by sliding the screen interface, for example Figure 5a As 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 can control the protocol fresh air system through the control interface to generate the first type of command. The user can turn on / off the fresh air system and adjust the air speed parameter on this interface. Swiping left on the first screen interface can switch to the second screen, which displays the floor heating control interface. The user can control the floor heating through the control interface to generate the second type of command. The user can turn on / off the floor heating, adjust the temperature parameter 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 devices, the user only needs to reselect the corresponding heating and ventilation device type on the device type configuration interface and click confirm. The temperature controller will restart and reset the control interface, so that the user can achieve the change of the target heating and ventilation device type controlled by the temperature controller without other complex setting operations.

[0100] Further, the temperature controller 100 can remotely connect 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 network configuration, parameter setting and remote control operation of the temperature controller 100 through the APP preinstalled on the terminal 200.

[0101] The control command received by the thermostat 100 can be originated from the instruction inputted by the user through the thermostat 100 itself, the APP sent to the main control module 135 and / or the upper computer software sent to the auxiliary control module 3151. When the control command is originated from the instruction sent by the upper computer software to the auxiliary control module 3151, the control method further comprises: directly regulating the auxiliary control module 3151 to control the first type of heating and ventilation equipment 501. When the control command is originated from the APP of the terminal 200, the control method further comprises: receiving the control command triggered by the terminal 200, and determining the control command as the first type of command and / or the second type of command according to the target heating and ventilation equipment type. Specifically, the user can trigger the control command through the APP, and after the thermostat 100 receives the control command triggered by the terminal 200, it determines whether the command belongs to the first type or the second type according to the target heating and ventilation equipment type selected by the user before. For the first type of command, it is forwarded to the auxiliary control module 3151 for format conversion and delivery, and for the second type of command, it is directly regulated to output the on-off module 32 for execution.

[0102] The interactive interface of the APP, i.e. the corresponding interactive mode, can be, for example Figure 5b As shown: in the case where the user does not select any heating and ventilation 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 (a) figure in the (a) figure, the interface displays “room temperature: 27℃ humidity: 43%”), and reminds the user to select the access equipment type on the thermostat 100 (for example Figure 5b In the (a) figure in the (a) figure, the interface reminds the user to select the access equipment type on the device screen”). When the user selects the corresponding heating and ventilation equipment type on the thermostat 100, the thermostat 100 will report the data related to the selected target heating and ventilation equipment type, so that the APP updates the interactive interface to the control interface of the corresponding heating and ventilation equipment type accordingly. Further, the interactive interface of the APP can be dynamically updated according to the change of the target heating and ventilation equipment type selected by the user. If the user only selects one heating and ventilation equipment type, the interactive interface of the APP only generates the interactive interface of the heating and ventilation equipment type, and does not generate the interactive interface of other heating and ventilation equipment types. If the user selects multiple heating and ventilation equipment types, the interactive interface of the APP can generate the interactive interfaces of multiple heating and ventilation equipment types, and the user can switch between multiple interactive interfaces. For example Figure 5b In the (b) figure, the user selects the interactive interfaces corresponding to three heating and ventilation equipment types, and the user can switch the interactive interfaces through the “air conditioner”, “floor heating” and “fresh air” options.

[0103] For example, the interactive interface of the heating and ventilation equipment of each sub-type under the air conditioner category can be shared. Further, when the interactive interface of the heating and ventilation equipment of each sub-type under the air conditioner category is shared, the user selects any sub-type (for example, air conditioner (flu machine), air conditioner (valve type), or air conditioner (virtual)) under the air conditioner category on the temperature controller 100, and the interactive interface of the APP is as shown in FIG. b of Figure 5b , which is the shared interactive interface of the heating and ventilation equipment of each sub-type under the air conditioner category, including: state display, switch control, air conditioner temperature adjustment, air conditioner mode adjustment, and air conditioner wind speed adjustment. The difference is that if the user selects air conditioner (flu machine) in the device type, when the temperature controller 100 receives the control command for the air conditioner sent by the APP, it will be determined as the first type of command, and then the auxiliary control module 3151 will be adjusted to control the protocol type flu machine central air conditioner. If the user selects air conditioner (valve type) in the device type, when the temperature controller 100 receives the control command for the air conditioner sent by the APP, it will be determined as the second type of command, and then the output on-off module 32 will be adjusted to control the fan coil central air conditioner.

[0104] Similarly, the floor heating and fresh air can also be processed in this way. For example, when the interactive interface of the heating and ventilation equipment of each sub-type under the fresh air category is shared, the user selects any sub-type (for example, fresh air (485), fresh air (valve type), or fresh air (virtual)) under the fresh air category on the temperature controller 100, and the interactive interface of the APP is as shown in FIG. c of Figure 5b , which is the shared interactive interface of the fresh air, including: state display, switch control, fresh air machine wind speed adjustment. The difference is that if the user selects fresh air (485) in the device type, when the temperature controller 100 receives the control command for the fresh air sent by the APP, it will be determined as the first type of command, and then the auxiliary control module 3151 will be adjusted to control the protocol type fresh air system. If the user selects fresh air (valve type) in the device type, when the temperature controller 100 receives the control command for the fresh air sent by the APP, it will be determined as the second type of command, and then the output on-off module 32 will be adjusted to control the fan of the valve type fresh air system. The shared interactive interface of the floor heating is as shown in FIG. d of Figure 5b , including state display, switch control, temperature adjustment.

[0105] In some embodiments, before receiving the user's selection of the type of heating and ventilation equipment 500, the control method further comprises: displaying a preset main interface. The basic content of the main interface can be default or set by the user, for example, as shown in FIG. Figure 5a , the basic content of the main interface can include background picture, date, time, networking status, etc.

[0106] After receiving the selection of the user on the type of the heating and ventilation device 500, the control method further comprises: generating a shortcut control corresponding to the selected target heating and ventilation device 500 type at a corresponding position of the main interface according to the selected target heating and ventilation device 500 type; the shortcut control is used to control the target heating and ventilation device 500.

[0107] The shortcut control is configurable content of the main interface and is dynamically changed based on the selection of the user on the type of the heating and ventilation device 500. In the case where the user selects multiple types of heating and ventilation devices, one shortcut control for each type of heating and ventilation device will be generated on the main interface, so as to facilitate the control of the heating and ventilation device through the main interface without going through the specific control interface of the heating and ventilation device.

[0108] As shown in the main interface of FIG. 1, the shortcut control is arranged at a lower position of the main interface, and when there are multiple shortcut controls, they are arranged in sequence. In the configuration process of the temperature controller 100, the user selects two types of heating and ventilation devices, which are floor heating (valve type) and fresh air (485), respectively. Therefore, two shortcut controls are generated on the main interface, as shown in FIG. 1, which are the shortcut control of the fresh air and the shortcut control of the floor heating from left to right. Both of the shortcut controls are used for start / stop control of the device. When the user clicks the shortcut control of the floor heating, the temperature controller 100 will control the floor heating to start. For example, when the user clicks the shortcut control of the floor heating again, the temperature controller 100 will control the floor heating to stop. Figure 5a Figure 5a

[0109] In addition, after the generation of the shortcut control, the control method further comprises: controlling the target heating and ventilation device 500 according to a first operation applied to the shortcut control; and / or jumping from the main interface to the control interface of the corresponding heating and ventilation device according to a second operation applied to the shortcut control. The number of clicks and the length of pressing between the first operation and the second operation are different at least in one aspect, so as to achieve different control purposes through different operations on the same shortcut control.

[0110] In some examples, the first operation is a single click, and the second operation is a long press of more than 3 seconds. Therefore, if a shortcut control is clicked, the temperature controller 100 will directly control the corresponding heating and ventilation device 500, such as starting / stopping the heating and ventilation device 500. If a shortcut control is pressed for more than 3 seconds, the temperature controller 100 will directly jump from the main interface to the control interface of the heating and ventilation device 500 corresponding to the shortcut control, so as to realize the direct jump of the control interface of the heating and ventilation device through the second operation, avoiding the cumbersome process of switching screens to find the required control interface.

[0111] ​​In addition, current temperature control technology has certain limitations in application, mainly reflected in that their control ability is limited to directly controlling the connected entity heating equipment through wired mode. This means that once the heating equipment is installed far away from the temperature controller, especially in those environments with large span or inconvenient wiring, the traditional wired connection method not only has high implementation cost, but also constitutes a not small challenge in the physical layer, which seriously limits the deployment flexibility and coverage of the temperature controller.

[0112] Based on this, an embodiment of the present application also provides a temperature controller control method, aiming to give the temperature controller the ability to build and manage virtual heating equipment, and design a virtual control interface matched therewith. Through the bridging role of the cloud platform or the intelligent binding technology between devices, these virtual avatars can accurately correspond to and remotely control the entity heating equipment actually installed in various environments, thereby skillfully realizing the "virtual-real integration" in the field of heating equipment control.

[0113] Specifically, in the present embodiment, before receiving the control command, the control method further includes S100 and S200. Wherein: S100, by selecting a target virtual heating equipment from a plurality of virtual heating equipment, a virtual control interface corresponding to the device type of the target virtual heating equipment is generated. The virtual heating equipment should be understood as non-physical heating equipment, and the interface of the temperature controller displays these selectable virtual heating equipment in the form of icons or text. Different device types require different control functions, and thus different device types correspond to different control interfaces. S200, display the virtual control interface, and according to the operation and control accepted by the virtual control interface, a communication module 134 controls the external device 600 that has established a communication relationship with the temperature controller 100.

[0114] It is worth noting that since the target virtual heating equipment only indicates the device type and is not associated with any entity controlled heating equipment 500, in the initial state after the virtual control interface is generated, it cannot control any entity controlled heating equipment 500, or in other words, before the user configures the corresponding entity controlled heating equipment 500 to the virtual control interface, the virtual control interface is in a free state, and the control event issued by the temperature controller 100 based on the operation and control received by the virtual control interface cannot trigger any entity controlled heating equipment 500.

[0115] After the virtual control interface is generated, the user needs to further configure the corresponding entity heating and ventilation equipment 500 for the virtual control interface. According to the different entity controlled heating and ventilation equipment 500 configured by the user, the entity heating and ventilation equipment 500 that can be matched and controlled by the virtual control interface is different, and thus the entity heating and ventilation equipment 500 that can be matched and controlled by the virtual control interface in this embodiment is variable. In other words, the configuration of the virtual control interface is divided into two steps: first, a free state virtual control interface that is not used to control any entity heating and ventilation equipment 500 is generated, and then the free state virtual control interface is further matched with the corresponding entity heating and ventilation equipment 500. The selection of the device type of the virtual control interface and the selection of the entity controlled heating and ventilation equipment 500 that can be controlled by the virtual control interface are both defined freely by the user.

[0116] Further, the control method provided in this embodiment generates a corresponding virtual control interface according to the user-selected virtual heating and ventilation equipment. The control interface truly simulates the main control elements and operation modes of the entity controlled heating and ventilation equipment 500, and further realizes the interaction between the virtual and the real by associating the virtual control interface with the control items of the entity heating and ventilation equipment 500, greatly improving the flexibility and convenience of the thermostat 100 control.

[0117] As shown in FIG. 14, the user can select a target virtual heating and ventilation equipment from a plurality of virtual heating and ventilation equipments. Figure 5c As shown in FIG. 14, the user can select a target virtual heating and ventilation equipment from a plurality of virtual heating and ventilation equipments. Figure 5c As shown in FIG. 14, the user can select a target virtual heating and ventilation equipment from a plurality of virtual heating and ventilation equipments. Figure 5c As shown in FIG. 14, the user can select a target virtual heating and ventilation equipment from a plurality of virtual heating and ventilation equipments.

[0118] Further, in S200, the regulation 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 action of the function control 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 the matched scene in the stored execution scene, and control the function of the external device 600 defined by the scene to be executed.

[0119] Specifically, the first event is associated with a current action of a target function control, which is a function control currently triggered on the virtual control interface, so that the gateway 400 and / or the cloud 301 can determine a matched execution scenario in the stored execution scenarios and control an executable function of the external device 600 defined by the execution scenario to be executed; the execution scenario stored by the gateway 400 and / or the cloud 301 is pre-defined by the user on the terminal 200; each execution scenario 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 use scenarios, the external device 600 can also be other smart devices, such as an air purifier, a sweeping robot, etc.

[0120] In the normal use stage, the first event sent by the temperature controller 100 based on the user's operation on the virtual control interface has a target direction and can trigger the corresponding executable function of the physical HVAC device 500 matched therewith. This control method takes the gateway 400 and / or the cloud 301 as a bridge, so that the temperature controller can control a wider range of external devices. The user is allowed to change the mapping relationship between each function 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 controlled by each function control of a 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 function control of a virtual control interface, so that the physical HVAC devices 500 controlled by each function control of a virtual control interface are the same, but the specific executable functions of the physical HVAC devices 500 controlled are different.

[0121] For example Figure 5c As shown, in the virtual control interface corresponding to the fresh air system, a switch control and a wind speed switching control are included, 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 forms a remote control interface of the fresh air system. Of course, the user can also match different physical HVAC devices 500 to different function controls of a virtual control interface, so that one virtual control interface can control multiple physical 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 forms a remote control interface of two HVAC devices 500.

[0122] Further, in the above embodiment, through the bridging role of the gateway / cloud platform, the problem that the temperature controller 100 can only control a single device or a fixed scene and cannot flexibly adjust the control range according to user needs is solved. By defining the execution scene, the function controls of the virtual control interface are associated with the executable functions of the multiple entity heating devices 500, the control of the temperature controller 100 on multiple devices and complex scenes is realized, and the flexibility and scalability of the control are improved.

[0123] The following further describes a possible use scenario of the above method: A user wants to control the protocol type fluorine machine central air conditioner in the living room and the bedroom through a temperature controller 100, wherein the temperature controller 100 is installed in the living room and is wired connected with 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 temperature controller 100 is too far, wiring is extremely troublesome. According to the scheme provided in the embodiment, the user can virtually define a virtual control interface of the protocol type fluorine machine central air conditioner through the temperature controller 100, and add the temperature controller 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 store the corresponding execution scene to the cloud. For example, define the execution scene A as that when the switch control on the virtual control interface is actuated, the on / off function item of the protocol type fluorine machine central air conditioner is linked, define the execution scene B as that when the mode switching control on the virtual control interface is actuated, the mode switching function item of the protocol type fluorine machine central air conditioner is linked, and define the execution scene C as that when the wind speed switching control on the virtual control interface is actuated, the wind speed switching function item of the protocol type fluorine machine central air conditioner is linked. In the subsequent use process, the user can directly control the living room floor heating connected with the temperature controller 100 through the output on-off module 32 of the temperature controller 100, and wirelessly control the protocol type fluorine machine central air conditioner in the bedroom through the virtual control interface provided by the temperature controller 100. The specific process of controlling the protocol type fluorine machine central air conditioner may, for example, be that when the user clicks the switch control on the virtual control interface to the “on” action, the temperature controller 100 will report the event of “the switch control is on” to the cloud 301, the cloud 301 matches the stored execution scene A based on the event, and based on the execution result defined by the execution scene A (i.e., the linkage of the on / off function of the protocol type fluorine machine central air conditioner), sends the control command of “turning on the air conditioner” 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 principle of other function controls (mode switching control, wind speed switching control) on the virtual control interface is similar. Through one temperature controller 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.

[0124] Further explanation, the user has a unique account and password on the corresponding application program of the terminal 200 (for example, the mobile phone 201), and adds the smart device based on the account and password logging into the application program. The smart device can be some controlled device (for example, a sweeping robot, a smart window opener, an air purifier, a heating device, etc.), or some controlled device (for example, a temperature controller 100, etc.). The smart device added to the account can be understood as a device added to the user, and the user has the right to manage (for example, delete, control function execution, configure parameters, etc.).

[0125] Among them, the heating device 500 and the temperature controller 100 with networking capability can be added to the application program of the user through the network configuration. Taking the network configuration of the temperature controller 100 as an example, the specific process of the network configuration can be, for example: when not in the network configuration state, a specified operation is performed on the temperature controller 100 to make it enter the network configuration mode. In a specific example, the specified operation can be, for example, triggering the "reset network" option displayed, and the temperature controller 100 will clear the existing network configuration information and enter the network configuration mode after detecting that the option is selected. In the network configuration mode, a request network message is sent outward (the request message can be sent outward in the form of broadcast through the Bluetooth communication protocol), so that the terminal 200 can scan and search the temperature controller 100 through the corresponding application program. After the user selects the temperature controller 100 to be configured and inputs the corresponding network configuration information, the terminal 200 sends the network configuration information to the corresponding temperature controller 100 (the network configuration information can be sent to the temperature controller 100 through Bluetooth direct connection), and the temperature controller 100 is connected to the network based on the network configuration information to complete the network configuration. In a specific example, when the temperature controller 100 supports WIFI communication, the network configuration information can be, for example, the name and password of the available WLAN network of a router 401, and the temperature controller 100 accesses the network of the router 401 based on the name and password. After completing the network configuration, the temperature controller 100 is added to the user, managed by the user, and the temperature controller 100 after the network configuration has the networking capability and can communicate with the gateway 400 and / or the cloud 301 to realize remote control and configuration.

[0126] Further, in S200, the control communication module 134 controls the external device 600 that establishes a communication relationship with the temperature controller 100, which can also include: sending the first event to the external device 600 according to the pairing relationship, the first event being used to trigger the external device 600 to adjust the working state to match the function control action manipulated on the virtual control interface.

[0127] The pairing relationship can be established in advance, the external device 600 can be a heating device 500, or can be other smart devices (for example, 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 can simultaneously establish a pairing relationship with multiple external devices 600. After establishing the pairing relationship, the thermostat 100 sends a first event to the switching device based on the operation received on the virtual control interface, and the first event is used to trigger the on-off state of a control channel of the switching device to switch to a state matched with the action of a target function control, and the target function control is a function control operated on the virtual control interface.

[0128] Further, according to this embodiment of the present application, through the intelligent binding technology (pairing) between devices, the thermostat 100 can directly communicate with the external device 600, and no longer needs to pass through the gateway 400 or the cloud 301, so that the control efficiency is higher and the control path is more stable.

[0129] 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 (for example, for more than 4 seconds) of the virtual control interface of the thermostat 100 and long-pressing a button (for example, for more than 4 seconds) of the wall switch, so that the two devices enter a pairing mode and send their own identification information (for example, a MAC address used to uniquely identify a device) to each other, so that the local storage of the identification information of the other party is completed. When the function control of the virtual control interface is operated subsequently, the thermostat 100 will send an action event, and the action event at least carries 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 stored locally, that is, it is determined that the action event is legal, and then the control channel of the corresponding button is switched 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 button is attracted, if the current action of the controlled function control is off, the relay of the control channel of the button is disconnected, and the thermostat 100 can cross-classify to control other external devices 600.

[0130] The utility model further provides a kind of thermostat 100, which can be used to realize the thermostat 100 control method provided in the above embodiment. Further, Figure 6~Figure 16In this part, the temperature controller 100 provided by the embodiments focuses on the detailed description of the hardware implementation scheme of the temperature controller 100, and the information interaction, execution process, implementation manner, principle, function, effect and the like between the modules in each of the following temperature controller 100 embodiments are based on the same concept as the control method embodiments of the utility model, and the specific content can be referred to the description in the method embodiments of the utility model. For the understanding of the same features / schemes, the embodiments may not be described in detail. Specifically, as shown in Figure 6 The temperature controller 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 the pin header (131 and 311), so that the auxiliary control module 3151 and the output on-off module 32 are electrically connected with the main control module 135. The main control module 135 is used for receiving various control commands; when receiving a first type of command, sending a corresponding control signal to the auxiliary control module 3151; when receiving a second type of command, controlling the output on-off module 32 to control the second type of heating and ventilation equipment 502. The output on-off module 32 can be controlled by the main control module 135 to switch on and off, and is used for controlling the second type of heating and ventilation equipment 502.

[0131] The auxiliary control module 3151 is pre-provided with a changeable data conversion standard, and is interconnected with the main control module 135 through a communication interface, for receiving the control signal, and performing format conversion according to the current set data conversion standard, so as to convert the received control signal into a data format recognizable by the first type of heating and ventilation equipment 501, and control the first type of heating and ventilation equipment 501 based on the converted data.

[0132] According to the above scheme, it can be known that the temperature controller 100 provided by the embodiments can control the valve type heating and ventilation equipment 500 (such as fan coil type central air conditioner, floor heating, valve type fresh air) and the protocol type heating and ventilation equipment 500 (such as protocol type air conditioner, protocol type fresh air) at the same time. The temperature controller 100 will receive a control command when working, which can come from a terminal 200 or other equipment, or come from the operation of the temperature controller 100 itself. The temperature controller 100 controls the valve type heating and ventilation equipment 500 or the protocol type heating and ventilation equipment 500 according to the control command. If the protocol type heating and ventilation equipment 500 is controlled, the control command will be converted into a signal in a format recognizable by the heating and ventilation equipment 500 through a protocol adaptation module integrated in the temperature controller 100, and then sent to the corresponding heating and ventilation equipment 500, so as to ensure that the heating and ventilation equipment 500 can recognize the signal and execute the corresponding function.

[0133] Further, the temperature controller 100 provided by the embodiment has strong compatibility and flexibility, and can realize dynamic change of the data conversion standard built in the auxiliary control module 3151 on the protocol type heating and ventilation equipment control, so as to achieve accurate "on-demand adaptation", provide users with wider choices, and meet different use requirements.

[0134] In a possible use scenario, the heating and ventilation equipment 500 installed in the user's home is a fluorine machine central air conditioner A, which is provided by a supplier 1, and the data conversion standard provided by the supplier 1 is a private data conversion standard 1. The fluorine machine central air conditioner A does not have a networking function and is configured with a control panel, and the user can control the fluorine machine central air conditioner A through the temperature controller 100 of the embodiment. Specifically, first, the temperature controller 100 is communicatively connected with the fluorine machine central air conditioner A, and then the data conversion standard in the auxiliary control module 3151 of the temperature controller 100 is preset as the private data conversion standard 1 through the terminal 200. Subsequently, the fluorine machine central air conditioner A can be controlled through the temperature controller 100 with the auxiliary control module 3151 as a medium. In this way, the temperature controller 100 endows the fluorine machine central air conditioner A with a panel control function and a networking intelligent function. If the user finds that the fluorine machine central air conditioner A is not easy to use after a period of use, and wants to replace it with a fluorine machine central air conditioner B, the fluorine machine central air conditioner B is provided by a supplier 2, and the data conversion standard provided by the supplier 2 is a private data conversion standard 2. After replacing the fluorine machine central air conditioner B, the user does not need to replace the temperature controller 100, but only needs to communicatively connect the temperature controller 100 with the fluorine machine central air conditioner B, and set the data conversion standard in the auxiliary control module 3151 as the private data conversion standard 2, so as to realize control of the fluorine machine central air conditioner B by the temperature controller 100.

[0135] Further, the data conversion standard currently set in the auxiliary control module 3151 is determined according to a configuration instruction, and the configuration instruction is generated after selection from a plurality of preset data conversion standards; each data conversion standard corresponds to a specific heating and ventilation equipment 500. Specifically, the auxiliary control module 3151 includes a protocol adaptation unit, which is integrated in the temperature controller 100 and serves as a bridge for connecting the protocol type heating and ventilation equipment. The data conversion standard in the protocol adaptation unit is changeable, and the user can match the corresponding data conversion standard for the protocol adaptation unit according to the actual connection of the heating and ventilation equipment of the temperature controller 100, so that the protocol adaptation unit can convert the received control command into a data format consistent with the stored data conversion standard.

[0136] In the example, the protocol adaptation 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 in a plurality 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 selects a WeChat applet as the operation platform, and the user searches and connects the Bluetooth of the auxiliary control module 3151 through the applet to realize direct wireless communication between the two.

[0137] Further, the user can select a matching data conversion standard for the auxiliary control module 3151 according to the first type of heating and ventilation equipment actually connected by the temperature controller 100, realize dynamic adjustment of the specific model of the protocol type heating and ventilation equipment supported by the temperature controller 100, so that the temperature controller has high configurability and dynamic adaptability, and can better meet the diversified needs of users.

[0138] Further, the temperature controller 100 further includes a temperature and humidity detection unit 122 for monitoring the temperature and humidity conditions of the environment where the temperature controller 100 is located; the output on-off module 32 includes a first relay assembly and a second relay assembly; when receiving a second type of command, the output on-off module 32 is regulated to control the second type of heating and ventilation equipment 502 connected thereto; specifically including: according to the temperature and humidity detection data, regulating the first relay assembly to control the valve of the fan coil type central air conditioner and / or floor heating in the second type of heating and ventilation equipment 502, and / or regulating the second relay assembly to control the fan of the valve type fresh air system in the second type of heating and ventilation equipment 502. Wherein, the temperature and humidity detection unit 122 can include a sensor for detecting temperature / humidity (such as the first sensor 12 referred to later) and other peripheral circuits used therewith.

[0139] Wherein the first relay assembly can include one or more relays, similarly, the second relay assembly can also include one or more relays, and the relay type is also different according to the different second type of heating and ventilation equipment 502 to be controlled. For example, the relay for controlling the high, medium and low gears of the fresh air system can be a single-pole single-throw relay 313, and the relay for controlling the floor heating or fan coil can be a single-pole double-throw relay 313.

[0140] In a specific example, for the control of water heating, the supply of hot water can be controlled by controlling the electric valve of the heating, thereby achieving the purpose of adjusting the temperature of the heating. For the control of valve type air conditioning (fan coil type central air conditioning), the cold 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 cold or hot air at a set wind speed to adjust the temperature. The electric valve involved above includes various types, and the control methods of different types are different. For example, it can include a three-wire electric valve (such as a three-wire two-control electric valve), which has two control lines for opening and closing, so that when controlling, the two control lines need to be controlled respectively, for example, when the valve opening line is conducted, the electric valve is opened, and when the valve closing line is conducted, the electric valve is closed. Further, a bidirectional motor control can be used, when the valve opening line and the zero line are conducted, the motor rotates to the left (or to the right), and the valve moves to the valve opening direction. When the valve closing line and the zero line are conducted, the motor rotates to the right (or to the left), and the valve is closed. It can also include a two-wire electric valve, the opening and closing control of which is completed by one line, and only the power-on state of one line needs to be controlled to control the opening and closing of the valve. Two-wire electric valves are divided into normally open valves and normally closed valves, and the normally open valve is in the open state when the control line is not powered, and conversely, the normally closed valve is in the closed state when the control line is not powered. The fan coil can include a two-pipe system and a four-pipe system. In the two-pipe system fan coil, one electric valve can be used to control a cold / hot coil to control the opening and closing of the cold / hot water, and in the four-pipe system fan coil, two electric valves are needed to control the cold water coil and the hot water coil respectively.

[0141] Further, according to this embodiment of the utility model, the output on-off module 32 of the temperature controller 100 includes two groups of relay components, the first group is used for controlling the valves of the fan coil type central air conditioner and the water heating, and the second group is used for controlling the fan of the fresh air system; when receiving the second type of command, the temperature controller 100 will respectively control the two groups of relays to realize the accurate control of different types of second type of heating and ventilation equipment 502.

[0142] Further, the temperature controller 100 further comprises a screen 14 electrically connected to the main control module 135 for displaying the control interface of the various heating and ventilation devices 500. Before receiving the control commands, the main control module 135 is further configured to receive the user's selection of the type of heating and ventilation device 500, and generate the corresponding control interface on the screen 14 according to the selected type of target heating and ventilation device 500. The generated control interface is then displayed, and the first type of command and / or the second type of command is generated through the operation of the interface to achieve the operation of the first type of heating and ventilation device 501 and / or the second type of heating and ventilation device 502. Specifically, the temperature controller 100 has a user input module with the screen 14, which provides a user interface, and the user can select the desired type of heating and ventilation device by clicking the icons or buttons on the screen 14. The main control module 135 includes a microcontroller and a corresponding control program, and according to the user's selection of the type of heating and ventilation device, the main control module 135 calls the corresponding control interface program stored in the memory to generate the control interface picture of the device. For example, if an air conditioner (flu machine) is selected, the control interface displayed includes temperature, wind speed and other function controls for controlling the temperature adjustment, wind speed switching and other function items of the air conditioner.

[0143] Further, the temperature controller of the present embodiment supports visual device selection, and automatically generates the corresponding control interface according to the user's selection of the type of heating and ventilation device. The user can issue control commands based on the control interface, which improves the versatility and adaptability of the temperature controller 100 and realizes the dynamic change of the type of target heating and ventilation device controlled by the temperature controller 100.

[0144] In addition, in the operation process of the temperature controller, the heat generated by the internal components of the temperature controller may affect the micro-environment temperature measurement around the built-in humidity detection unit, thereby affecting the accuracy of the readings. In order to improve the accuracy of temperature and humidity measurement and ensure the reliability of the ambient temperature, the temperature controller of the utility model designs an innovative function, which allows users to independently compensate the temperature and humidity value (i.e. manually adjust the detection data (humidity value and / or temperature value) collected by the temperature and humidity detection unit 122), so as to make targeted correction to obtain more accurate environmental temperature / humidity readings. In specific implementation, the temperature controller opens a friendly adjustment module, which gives users the ability to fine-tune and correct the temperature readings measured by the temperature and humidity detection unit 122 within ±10℃ (with 1℃ as the step adjustment resolution). This means that users can make fine adjustments to the initial temperature value measured by the temperature and humidity detection unit within ±10℃ according to actual conditions or perceived environmental differences (for example, allowing users to adjust the currently displayed temperature value within ±5℃ through the temperature controller interface), thereby compensating for errors caused by internal heating and other factors, making the final displayed temperature result more accurate and close to the real environmental state, significantly enhancing the adaptability and control accuracy of the temperature controller under different working conditions. For example, the user finds that the temperature value displayed by the temperature controller is 30℃, but the actual environmental temperature is 26℃, at this time the user can compensate the current displayed temperature value by-4℃ through the adjustment module provided by the temperature controller, and the temperature controller will subtract 4 degrees Celsius from the actual measured temperature value of 30℃ and display it as the final temperature value on the interface. Subsequently, according to the adjusted (corrected) temperature value, the first relay component controls the fan coil type central air conditioner and / or the valve of the floor heating in the second type of heating and ventilation equipment 502, and / or the second relay component controls the fan of the valve type fresh air system in the second type of heating and ventilation equipment 502.

[0145] Further, the temperature controller 100 further comprises a proximity sensor 132 for detecting whether the user is close to the temperature controller 100. The proximity sensor 132 may, for example, use a microwave radar module, an infrared sensor unit, etc. to detect the human body.

[0146] Before receiving the user's selection of the type of heating and ventilation 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 heating and ventilation equipment 500, the main control module 135 is also used to: display the main interface when it is determined that the user is close to the temperature controller 100; the main interface has a shortcut control; the shortcut control is a shortcut control corresponding to the target heating and ventilation equipment 500 type generated according to the selected target heating and ventilation equipment 500 type, and is used to control the target heating and ventilation equipment 500.

[0147] The shortcut control belongs to the configurable content of the main interface and is dynamically changed based on the selection of the user on the type of the heating and ventilation device 500, and in the case that the user selects multiple types of heating and ventilation devices, a shortcut control for each type of heating and ventilation device is generated on the main interface, so as to facilitate the control of the heating and ventilation device through the main interface without the specific control interface of the heating and ventilation device.

[0148] Further, before receiving the control command, the main control module 135 is further configured to generate a virtual control interface corresponding to the device type of a target virtual heating and ventilation device by selecting the target virtual heating and ventilation device from a plurality of virtual heating and ventilation devices. The virtual control interface is displayed, and the communication module 134 is controlled to control the external device 600 in communication with the temperature controller 100 according to the control accepted by the virtual control interface. The virtual heating and ventilation device should be understood as a non-physical heating and ventilation device, and the interface of the temperature controller displays these selectable virtual heating and ventilation devices in the form of icons or text. Different device types require different control functions, and thus different control interfaces corresponding to different device types. Further, the temperature controller 100 provided in the embodiment can generate a corresponding virtual control interface according to the selected virtual heating and ventilation device of the user, the control interface truly simulates the main control elements and operation mode of the physical controlled heating and ventilation device 500, and further associates the virtual control interface with the control item of the physical heating and ventilation device 500, thereby realizing the interaction between the virtual and the real, and greatly improving the flexibility and convenience of the temperature controller 100.

[0149] Reference Figure 7 As shown in the drawings, in order to further disclose the structure and working principle of the temperature controller 100 of the embodiment of the utility model, the partial circuit structure schematic diagram of the temperature controller 100 is illustrated.

[0150] Specifically, in this embodiment of the utility model, the main control module 135 uses embedded SOC chip, communicates and connects with the auxiliary control module 3151 through serial port, connects with the communication module 134 through USB port, and is electrically connected with the output on-off module 32 through the drive circuit to drive the output on-off module 32.For example, the SSD201 chip of sigmastar, SSD201 is a highly integrated embedded SOC chip, and the chip is based on ARM Cortex-A7 dual-core 1.2GHz;Integrates hardware H.264 / H.265 video decoder;Built-in 64MB DDR;Built-in 2D graphics engine;Support TTL (RGB88, 1280*800) / MIPI (1920*2080) screen display driver interface;Built-in Ethernet mac and PHY;Built-in audio codec, etc.;Support Secureboot, AES / DES / 3DES password engine, security boot and personalized identity verification mechanism to protect the system.Among them, the SSD201 chip is connected with the auxiliary control module 3151 in communication through serial port, is connected with the communication module 134 through USB port, and is electrically connected with the output on-off module 32 through the drive circuit to drive the output on-off module 32.The high level reset PM_RESET of SSD201 chip, AVDD1P2_MIPI (Pin75) connects 0.1uF capacitor, guarantees that the chip internal LDO is stabilized, DVDD_DDR_RX (Pin50) connects 470nF~1uF capacitor to GND, GND_EFUSE (Pin24) connects 10KΩ resistance to GND, and is not directly connected with chip ePAD, and the built-in DDR2-1333 of SSD201, the power supply of DDR2 is 1.8V.USB line is connected with ESD protection device ESD5V0B02-1006, which has 0.18pF ultra-low parasitic capacitance, can be applied to USB / DP / MDDI / PCIe / SATA high-speed applications, and the protection capacity reaches 23kV air discharge, 20kV contact discharge.SSD201 supports SPINAND and SPINOR start, selects through the pull-up and pull-down resistance of PM_SPI_CLK, pull-down from SPINOR start, and pull-up SPINAND start selects from spi nand flash start.

[0151] Further, in this embodiment of the utility model, the screen 14 adopts LCD touch screen, be used to show the control interface of each kind of heating equipment 500 generated by host module 135, for example including 4.0-inch LCD screen + touch screen + backlight. Host module 135 controls drive power supply through a MOS tube, to control the on / off of the power supply, to facilitate the control power-on timing (after the core board is powered on stably, then power supply and drive screen 14 for screen 14), avoid the whole machine work not normal due to power-on timing problem. In addition, through the MOS tube, host module 135 can also power on screen 14 again to reset screen 14. ME2212AM6G is used as the LED drive chip of backlight.

[0152] Further, in this embodiment of the utility model, the proximity sensor 132 adopts the circuit or combination of circuit with human body sensing and light sensing functions, for example, LTR-X1503 chip of Guangbao, which communicates with the SSD201 chip of host module 135 through IIC.

[0153] Further, 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 Zhongke Yinhui Chip, which also communicates with the SSD201 chip of host module 135 through IIC.

[0154] Further, in this embodiment of the utility model, the auxiliary control module 3151 can be understood as a circuit or combination of circuit with data storage and processing capability, which can store the data conversion standard and support users to change the stored data conversion standard according to the demand, in order to adapt to specific heating equipment 50. In some examples, the auxiliary control module 3151 specifically includes a protocol adaptation unit and a 485 communication circuit, wherein the protocol adaptation unit includes a control unit and a communication unit, the control unit is preloaded with 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 adaptation unit and the 485 communication circuit are communicated and interconnected, and the 485 communication circuit is externally provided with a 485 protocol fresh air interface for connecting a protocol type fresh air system. The protocol adaptation unit is also directly externally provided with a bus protocol interface for connecting a protocol type fluorine machine central air conditioner.

[0155] The data conversion standard can be understood as a communication protocol for data conversion. It can be understood that the communication protocol used by the supplier is generally private, and the private communication protocols used by different suppliers are different, so the specific content of the protocol is also specific to the specific HVAC equipment 500. Therefore, different users may purchase HVAC equipment 500 from different suppliers, brands / models when considering many factors such as brand effect, equipment quality, equipment price, etc. In the embodiment, the auxiliary control module 3151 is integrated inside the temperature controller 100, and the wiring port (such as the communication terminal 316 involved in the later embodiment) for connecting the HVAC equipment 500 is provided outside the shell of the temperature controller 100, so that the temperature controller 100 of the embodiment has wider versatility.

[0156] An exemplary circuit of the auxiliary control module 3151 may, for example Figure 11 As shown, the protocol adaptation unit and the communication unit are integrated into a drive-by-wire module MD1 with control and communication functions, the 485 communication circuit is built with a MAX3485ESA chip, the drive-by-wire module can establish Bluetooth direct communication with the terminal 200 to configure the internal data conversion standard, the drive-by-wire module MD1 communicates with the SSD201 chip of the main control module 135 through the serial port (S2-TX, S2-RX), and establishes connection through the 485 bus and the 485 communication circuit to send signals for controlling the protocol new air system outside through the 485 communication circuit. In addition, as shown Figure 11 The drive-by-wire module MD1 and the 485 communication circuit are connected to the outside through the J2 interface to set the interface for connecting the first type of HVAC equipment (the J2 interface can be understood as the communication terminal 316 involved in the later embodiment), for example Figure 11 In the embodiment, the 1 and 2 interfaces of J2 are used to connect the protocol new air system, and the 3-8 interfaces are used to connect the protocol type fluorine machine central air conditioner.

[0157] Further, as shown Figure 8 In this embodiment of the utility model, in the output on-off module 32, the first relay assembly includes a single pole double throw relay 314 (RL4), and the second relay assembly 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 the floor heating or fan coil type central air conditioner, and the three single pole single throw relays 313 are used to control the high, medium and low speed gears of the valve type new air system or the high, medium and low speed gears of the fan coil type central air conditioner. Further, in this example, as shown Figure 8When the user controls the fan-coil type central air conditioner through the temperature controller 100, the single-pole double-throw relay 314 needs to be connected to the fan-coil valve control port of the fan-coil type central air conditioner, and the three single-pole single-throw relays 313 need to be connected to the high, medium and low three gear valves of the fan-coil type central air conditioner, so as to control the opening and closing of the fan-coil valve through the single-pole double-throw relay 314, so as to achieve the purpose of refrigeration / heat, and control the switching of high, medium and low wind speed through the three single-pole single-throw relays 313. When the user controls the valve type fresh air system through the temperature controller 100, the three single-pole single-throw relays 313 need to be connected to the high, medium and low three gear valves of the valve type fresh air system, so as to switch the high, medium and low wind speed of the fresh air system through the on / off of the three single-pole single-throw relays 313. When the user controls the floor heating through the temperature controller 100, the single-pole double-throw relay 314 of the temperature controller 100 needs to be connected to the water pipe valve of the floor heating, and then the heating of the floor heating is controlled through the single-pole double-throw relay 314.

[0158] Further, the main control module 135 drives each relay in the output on-off module 32 through a driving circuit. As shown in some examples, Figure 7 and Figure 8 The driving circuit adopts ULN2003A Darlington tube, and the SSD201 chip is connected to the input end of the ULN2003A through RELAY-1-RELAY-4, and the output end of the 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 the ULN2003A. Using one Darlington tube to drive multiple relays of the output on-off module 32 can effectively reduce the space occupied by the driving circuit. Each relay in the output on-off module 32 is connected to the outside through the wiring terminal 312. How to realize the connection will be described below, and will not be described here.

[0159] In addition, in this embodiment of the utility model, the temperature controller 100 further includes a power circuit, which includes a strong power conversion circuit (provided on the power circuit board 31) and a weak power conversion circuit (provided on the control circuit board 13), wherein the strong power conversion circuit adopts an isolation flyback switching power supply scheme, which can output 5V / 1A, meeting the power supply output of the load and chip on the control circuit board 13. The weak power conversion circuit is used to further convert the voltage output by the strong power conversion circuit into the power supply voltage required by each chip, for example, the BL8039 chip of Shanghai Beling is used to convert 5v into 3.3V, 1.8V and 1.0V, and is used to supply power to the SSD201 chip, wherein the 1.8V voltage is used for DDR power supply inside the SSD201 chip, and the 1.0V voltage is used for kernel power supply inside the SSD201 chip.

[0160] Further, in this embodiment, there is a power-on timing requirement between 1V and 3.3V, 1V needs to be powered on after 3.3V, and the principle of 5V to 1V circuit can be, for example Figure 9 As shown, the master 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. Based on, for example Figure 9 As shown in the circuit, the principle of adjusting the power supply voltage of the SSD201 chip can be, for example: when starting, pull up SAR_GPIO1 to make the 5V to 1V circuit output a voltage close to 1V (actually (49.9+75) / 75*0.6V=0.9992V), and after starting, control SAR_GPIO1 to pull down, control the power supply voltage of the SSD201 chip to pull down to about 0.9V (actually (49.9+100) / 100*0.6V=0.8994V), in order to achieve the purpose of reducing power consumption.

[0161] Further, in this embodiment of the utility model, the communication module 134 adopts the circuit or combination of circuits with WIFI and Bluetooth functions. For example, SKI.WB800DCU.1B22322 module supports WIFI and Bluetooth 5.2, uses USB and SSD201 chip of the master module 135 to communicate, supports IEEE 802.11b / g / n / ax&BT5.2 standard from 2.4-2.5GHz. The specific circuit principle diagram of SKI.WB800DCU.1B22322 module can be as shown in Figure 10 As shown, USB1_N and USBN_P are connected with the SSD201 chip of the master module 135. 3.3V power supply is adopted, and a decoupling capacitor is arranged on the USB data line, which can reduce the radiation of the USB line and reduce the interference on the sensitivity. RF is an antenna interface, which needs to control the impedance according to 50Ω. In order to facilitate the adjustment of radio frequency performance, a Π type matching circuit is reserved between the RF port and the antenna, and the Π circuit is placed close to the antenna.

[0162] The working principle of the temperature controller 100 is further explained by taking a specific scene as an example: for example, the user's home is installed with a water floor heating system and a Daikin MX ducted air conditioner (4 cores) central air conditioner. Taking this scene as an example, the use principle of the temperature controller 100 can be, for example:

[0163] When the user gets the temperature controller 100 device, first connect the water floor heating system and the Daikin MX ducted air conditioner (4-core) central air conditioner with the temperature controller 100. Connect the valve control line of the water floor heating system to the first relay assembly of the output on-off module 32, specifically to the RL4 relay port in the first relay assembly. The Daikin MX ducted air conditioner (4-core) central air conditioner is a protocol type fluorine machine central air conditioner, so its wiring terminal is connected with the wiring terminal of the auxiliary control module 3151 of the temperature controller 100, specifically the S21 terminal of the Daikin MX ducted air conditioner (4-core) central air conditioner is connected with 5-8 (A1, B1, X, Y) in the J2 port of the protocol adaptation unit. It needs to be explained here that the wiring method of the first type of heating and ventilation equipment 501 and the auxiliary control module 3151 may be different for different models, and in actual use, the user can connect according to the specific model of the heating and ventilation equipment 500, in addition, the temperature controller 100 can also give a wiring instruction of all the first type of heating and ventilation equipment 501 it supports when it leaves the factory, so that the user can refer to the wiring. Then connect the zero fire line to the temperature controller 100, and connect the power supply, power on and complete the SSD 201 initialization boot, the output voltage of the 5V to 1V circuit controlled by the SSD 201 of the main control module 135 reduces to about 0.9V, the screen 14 is lit, and the screen 14 displays the preset main interface. Then the user can search the Bluetooth of the auxiliary control module 3151 through the WeChat applet of the mobile phone 201 and establish a direct connection, then select the data conversion standard corresponding to the Daikin MX ducted air conditioner (4-core) central air conditioner for the auxiliary control module 3151 on the WeChat applet, and the auxiliary control module 3151 automatically downloads the corresponding data conversion standard from the cloud 301 based on the user's selection on the WeChat applet and installs it locally for subsequent use. At this time, the temperature controller 100 is used for the first time, and has not been configured by the user, so the system defaults the best configuration, that is, the best control scheme of the temperature controller 100: air conditioner (fluorine machine), fresh air (valve type), floor heating (valve type), the first screen of the temperature controller 100 is the control interface of the air conditioner (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), and the main screen displays the shortcut controls of the three heating and ventilation equipment 500, as shown in Figure 12 After that, the user can enter the temperature controller 100 setting interface by performing a pull-down operation from any interface, and the interface displays a plurality of setting options, as shown in Figure 13As shown, the "Main Screen Settings" option allows you to configure the main screen, such as setting the content, background, and layout; the "Screen 14 Brightness" option allows you to adjust the brightness of the screen 14; the "System Settings" option allows you to configure some settings for the thermostat 100 system, such as network information display, network reset, device restart, factory reset, etc.; the "Touch Feedback" option allows you to configure the touch feedback of the screen 14, such as the buzzer sound when the touch is turned off / on; the "About This Device" option displays some version information of the thermostat 100, such as software version number and MAC address; and "Device Type" is used to access the configuration interface for the HVAC equipment type 500.

[0164] like Figure 12 As shown, the user enters the corresponding configuration interface by clicking the "Device Type" option, and then reselects the HVAC equipment type 500 on this interface. Based on the HVAC equipment 500 in the user's home, the user needs to select air conditioning (refrigerant-based) or underfloor heating (valve-based). The corresponding main screen interface will then generate shortcut controls for air conditioning (refrigerant-based) and underfloor heating (valve-based). The first screen is the control interface for air conditioning (refrigerant-based), used to control the Daikin MX ducted central air conditioning unit (4-core). The second screen is the control interface for underfloor heating (valve-based), used to control the underfloor heating system. Subsequently, the LTR-X1503 monitors whether anyone is approaching (e.g., whether someone is within 30cm of the thermostat). If no one is detected for a specified period, the screen turns off and goes into standby mode. Afterwards, it monitors in real time whether someone is present and whether the screen 14 is touched. Furthermore, in this embodiment, the proximity sensor 132 also has light sensing capabilities to automatically adjust the brightness of the screen 14 according to the light intensity. The LTR-X1503 is a sensor chip with light sensing capabilities.

[0165] Upon detecting a person and / or a touch operation on screen 14, the screen lights up and displays the main interface. Subsequently, the SSD201 chip of the main control module 135 reads the touch data via the IIC interface to determine the touched function control, and then determines whether the control command generated based on screen 14 is a first-type command or a second-type command (where the touched function control is a function control of the control interface of the first-type HVAC equipment 501, then it is a first-type command; if the touched function control is a function control of the control interface of the second-type HVAC equipment 502, then it is a second-type command). If the user operates a shortcut control on the main interface, the corresponding HVAC equipment 500 is directly controlled to turn on / off. If the user operates a control on the main screen, the auxiliary control module 3151 controls the fresh air (485). If the user operates a control on the secondary screen, the first relay component (RL4) in the output on / off module 32 controls the valve of the underfloor heating (valve type).

[0166] See Figure 14~Figure 15The temperature controller 100 provided by the embodiment of the utility model is specifically illustrated. The temperature controller 100 is a deformation of the temperature controller 100 of the previous embodiment. In particular, in this embodiment of the utility model, the auxiliary control module 3151 is not integrated in the temperature controller 100, but is electrically connected with the heating and ventilation equipment 500, and the temperature controller 100 and the auxiliary control module 3151 are connected through a wired connection. For example, for the control of the protocol type fluorine machine central air conditioner, the auxiliary control module 3151 can be directly arranged in the indoor unit or the outdoor unit of the protocol type fluorine machine central air conditioner, and is used for providing data format conversion for the protocol type fluorine machine central air conditioner. Through the intermediate medium of the auxiliary control module 3151, the temperature controller 100 can conveniently control various brands / models of the first type of heating and ventilation equipment 501.

[0167] Specifically, as shown in the embodiment of the utility model, the temperature controller 100 comprises a main control module 135, an output on-off module 32 and a communication module 134, the communication module 134 is electrically connected with the main control module 135, and the main control module 135 communicates outwardly through the communication module 134. The output on-off module 32 can be switched on and off under the control of the main control module 135, and is used for controlling the second type of heating and ventilation equipment 502. Figure 14

[0168] The main control module 135 is used for receiving various control commands; when receiving the first type of command, the corresponding control signal is sent to the auxiliary control module 3151; when receiving the second type of command, the output on-off module 32 is regulated to control the second type of heating and ventilation equipment 502.

[0169] The auxiliary control module 3151 is preset with changeable data conversion standards, and is interconnected with the first type of heating and ventilation equipment 501 through a communication interface, and is used for, after receiving the control signal, carrying out format conversion according to the current set data conversion standard, so as to convert the received control signal into a data format that can be recognized by the first type of heating and ventilation equipment 501, and controls the first type of heating and ventilation equipment 501 based on the converted data.

[0170] Further, the temperature controller 100 provided by the embodiment integrates the auxiliary control module 3151 at the heating and ventilation equipment end, so that the temperature controller 100 only needs to send a conventional control signal to the heating and ventilation equipment, and in the case of dynamically changing the data conversion standard, the temperature controller 100 of the embodiment has a wider design space due to not needing to layout the auxiliary control module 3151.

[0171] ​Further, the temperature controller 100 is internally integrated with a 485 communication circuit (for transmitting control signals of fresh air (485)) and / or an air conditioner bus (for transmitting control signals of air conditioners (flu machines)), which is electrically connected to the main control module 135 and connected to the auxiliary control module 3151 arranged at the end of the heating and ventilation equipment 500, so as to serve as a bridge for connecting the temperature controller 100 to the heating and ventilation equipment 500 and for receiving the control signals sent by the main control module 135. When the control signals are control signals for air conditioners (flu machines), the control signals are transmitted to the auxiliary control module 3151 through the air conditioner bus, and when the control signals are control signals for fresh air (485), the control signals are converted into 485 communication format by the 485 communication circuit and then sent to the auxiliary control module 3151.

[0172] In addition, as shown in Figure 15 In order to further expand the types of heating and ventilation equipment 500 supported by the temperature controller 100, in this embodiment of the utility model, an infrared emission circuit is added, which is electrically connected to the main control module 135 and used to send the control signals of the main control module 135 in the form of infrared signals, so as to realize the control of indoor cabinet machines and hanging machines.

[0173] In the implementation process of the scheme, the distance and angle between the temperature controller 100 and the air conditioner cabinet machine and the hanging machine need to be controlled, so that the infrared signals between them can be transmitted smoothly. The main control module 135 of the temperature controller 100 is integrated with multiple infrared coding formats of air conditioners in software, and 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 signals.

[0174] In some examples, the main control module 135 sends a 38K carrier signal to the cabinet machine air conditioner and the hanging machine air conditioner through the infrared emission tube of the infrared emission circuit. The cabinet machine and the hanging machine have an infrared receiving circuit inside, which converts the 38K carrier signal emitted by the temperature controller 100 into a square wave signal recognizable by the internal MU, decodes it according to the coding format, and executes corresponding actions such as power on / off, mode switching, wind speed adjustment, timing, etc.

[0175] Referring to Figure 16 The temperature controller 100 provided by an embodiment of the utility model is specifically illustrated. The temperature controller 100 is a variation of the temperature controller 100 of the above-mentioned embodiment. In particular, compared with the temperature controller 100 of the previous embodiment, in this embodiment of the utility model, the auxiliary control module 3151 is not integrated in the temperature controller 100, but is electrically connected to the heating and ventilation equipment 500, and the temperature controller 100 and the auxiliary control module 3151 are connected through wireless connection, so as to avoid the communication wiring between them.

[0176] Specifically, as shown in Figure 16As shown, in this embodiment of the utility model, the temperature controller 100 includes main control module 135, output on-off module 32 and communication module 134, communication module 134 is electrically connected with the main control module 135, and the main control module 135 communicates outwardly through the communication module 134.The output on-off module 32 can be switched on and off under the control of the main control module 135, and is used for controlling the second type of heating and ventilation equipment 502.

[0177] The main control module 135 is used for receiving various control commands, when receiving the first type of command, the communication module 134 is regulated to send corresponding control signals to the auxiliary control module 3151 in a wireless manner, and when receiving the second type of command, the output on-off module 32 is regulated to control the second type of heating and ventilation equipment 502.

[0178] The auxiliary control module 3151 is preset with changeable data conversion standards, and is interconnected with the first type of heating and ventilation equipment 501 through a communication interface, and is used for receiving the control signals, and performing format conversion according to the current set data conversion standards, so as to convert the received control signals into a data format that can be recognized by the first type of heating and ventilation equipment 501, and control the first type of heating and ventilation equipment 501 based on the converted data.

[0179] Further, the temperature controller 100 provided by the embodiment integrates the auxiliary control module 3151 at the heating and ventilation equipment end, so that the temperature controller 100 only needs to send a conventional control signal to the heating and ventilation equipment, and in the case of dynamically changing the data conversion standard, the temperature controller 100 of the embodiment has more flexible installation space and wider coverage range due to the fact that it does not need to be connected with the heating and ventilation equipment 500 by wire.

[0180] Further, the auxiliary control module 3151 includes a protocol adaptation unit and a protocol converter, the protocol converter is electrically connected with the protocol adaptation unit through a 485 bus, and is used for receiving the wireless control signals sent by the temperature controller 100, and sending the control signals to the protocol adaptation unit after converting the control signals into a 485 communication format, so that the protocol adaptation unit can be recognized.

[0181] In some examples, the communication module 134 can adopt WIFI-Bluetooth dual-mode communication, and then communicate with the cloud through WIFI, and realize wireless communication with the auxiliary control module 3151 installed at the heating and ventilation equipment 500 end through Bluetooth (BLE). The protocol converter of the auxiliary control module 3151 can adopt a 485-to-Bluetooth protocol converter, which can convert the 485 signals sent by the protocol adaptation unit into Bluetooth format and send them to the temperature controller 100, and also can convert the Bluetooth signals sent by the temperature controller 100 into 485 format and send them to the protocol adaptation unit.

[0182] As Figure 17 to Figure 32The utility model also provides a temperature controller 100, this temperature controller 100 can be used to realize the temperature controller control method provided by above-mentioned embodiment. Further, in order to understand its structure and implementation mode in depth, we can refer to Figure 17 to Figure 32 These figures exemplify the physical form of the temperature controller 100, which not only embodies the design concept, but also serves as the physical carrier of the control logic and hardware structure of the temperature controller 100. Based on this, the following embodiments aim to disclose the specific design structure and hardware details of the temperature controller. The temperature controller 100 provided by these embodiments can be implemented independently or combined with the software and hardware logic in the above-mentioned embodiments to form a complete and efficient temperature controller system solution.

[0183] Firstly, it can be understood that the temperature controller will generate significant heat effect during normal operation, which directly interferes with and affects the accurate measurement of the environmental temperature and humidity by the internal detection elements, thereby affecting the reliability of the temperature and humidity detection data. In addition, the heat generated by the temperature controller under different operating conditions is not constant but dynamic, which undoubtedly aggravates the difficulty of quantifying the interference of the internal heat effect on the temperature and humidity detection. Therefore, how to effectively suppress the negative impact of the heat generated by the temperature controller on the temperature and humidity detection data has become a technical problem to be solved.

[0184] Based on this, the purpose of one embodiment of the utility model is to improve the problem of insufficient accuracy of the existing temperature controller in environmental temperature and humidity detection. As Figure 17- Figure 27 shown, the utility model provides a temperature controller 100, which is specifically illustrated, and the temperature controller 100 is suitable for installation on a wall. Specifically, the temperature controller 100 includes a panel shell 11 and a first sensor 12, the first sensor 12 is arranged on the inner side of the panel shell 11 and is used for detecting temperature and / or humidity; wherein, as Figure 26 shown, the panel shell 11 has a first bottom wall 111, the distance between the first sensor 12 and the first bottom wall 111 is less than 5mm, and the first bottom wall 111 is provided with a ventilation hole 112 at the position corresponding to the first sensor 12; when the temperature controller 100 is installed on the wall, the first bottom wall 111 is located at the bottom of the panel shell 11, and the ventilation hole 112 is open downward. Wherein, the temperature controller 100 can be understood as a device capable of executing switching action in response to user operation, or a device capable of controlling other equipment to execute switching action in response to user operation. In some exemplary embodiments, the temperature controller 100 can be a wall switch, a temperature controller, etc. The first sensor 12 can be understood as a temperature sensor, a humidity sensor, or a sensor capable of detecting temperature and humidity simultaneously.

[0185] The temperature controller 100 provided by the utility model, the first sensor 12 is arranged at the position close to the bottom of the panel shell 11, which is far away from the position with the largest heat emission and can avoid the movement route of heat, thereby reducing the influence of heat emission of the temperature controller 100 on temperature and humidity detection.In addition, the air hole 112 is arranged within the distance of 5mm below the first sensor 12, the air hole 112 penetrates the inside and outside of the panel shell 11, so that the temperature and humidity at the position of the first sensor 12 is 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 1.2mm.

[0186] It is worth noting that the downward opening of the air hole 112 has the following beneficial effects: (1) since heat has the physical property of upward movement, the temperature and humidity below the temperature controller 100 is closer to the ambient temperature and humidity, and the downward opening of the air hole 112 can facilitate the entry of air below into the air hole 112, thereby improving the accuracy of temperature and humidity detection; (2) the downward opening of the air hole 112 makes it difficult for dust to fall into the air hole 112; (3) when multiple temperature controllers 100 are installed side by side, the air hole 112 will not be blocked by the temperature controllers 100 on the left and right sides.

[0187] Further, as shown in Figure 22- Figure 26 , the panel shell 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 shell 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, thereby enabling the first sensor 12 to be arranged at the corner of the panel shell 11. Since the position with the largest heat emission of the temperature controller 100 is located at the center position, arranging the first sensor 12 at the corner of the panel shell 11 can be away from the position with the largest heat emission, reducing the influence of heat on the first sensor 12, and improving the detection accuracy of the first sensor 12. 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 shell 11. In a preferred embodiment, the distance between the first sensor 12 and the first side wall 113 is 1.4mm.

[0188] Further, the position design related to the first sensor 12 and the structure design of the air hole 112 will try to improve the influence of the heat effect generated inside the temperature controller 100 on the measurement of ambient temperature and humidity during normal operation, and in combination with the temperature and humidity compensation scheme in the above embodiment, the accuracy of the temperature and humidity measurement data can be significantly improved.

[0189] Further, as shown in Figure 17 , Figure 18 and Figure 24As shown, the panel housing 11 is provided with a screen 14, which is electrically connected to the control circuit board 13. Since the screen 14 generates a significant amount of heat when lit, and this heat is mainly concentrated in the display area 141 of the screen 14, the display area 141 is... Figure 17 and Figure 18 The area enclosed by the dashed frame is designed to reduce the impact of heat generated by the screen 14 on the first sensor 12, such as... Figure 24 As shown, with a plane parallel to the control circuit board 13 as the projection plane, the display area 141 of the screen 14 projects onto the projection plane to form a first projection pattern 142. Figure 24 The first sensor 12 is projected onto the projection plane to form a second projected image (not shown in the figure). The first projected image 142 and the second projected image do not overlap, thereby reducing the heat transfer from the display area 141 to the first sensor 12. Furthermore, besides the screen 14, another heat source for the temperature controller 100 is the electronic components on the circuit board. To reduce the impact of the electronic components' heat on the first sensor 12, in this embodiment, the control circuit board 13 is projected onto the projection plane to form a third projected image (not shown in the figure). The third projected image also does not overlap with the second projected image, thereby reducing the heat transfer from the control circuit board 13 to the first sensor 12.

[0190] In some embodiments, such as Figure 19 and Figure 31 As shown, the temperature controller 100 also includes a bottom shell 3, inside which a power circuit board 31 is disposed. The power circuit board 31 is connected to the control circuit board 13 via pin headers 131 and female headers 311. The power circuit board 31 is connected to 220V high voltage and has a power module, including a transformer 318, which converts high voltage to low voltage to provide power to the control circuit board 13. To reduce the impact of heat generated by the power circuit board 31 on the first sensor 12, in this embodiment, an isolation plate 5 is disposed between the power circuit board 31 and the control circuit board 13. The isolation plate 5 covers the bottom shell 3, and the power circuit board 31 is contained within the bottom shell 3 and the isolation plate 5. Thus, the isolation plate 5 can isolate some of the heat from the power circuit board 31 inside the bottom shell 3, reducing heat transfer to the panel housing 11 and reducing the impact of the power circuit board 31 on the detection accuracy of the first sensor 12. The bottom shell 3 is surrounded by mounting parts 4, and the panel shell 11 is detachably connected to the mounting parts 4. It is worth mentioning that the isolation plate 5 also has the function of electrical isolation, 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.

[0191] Further, the power supply circuit board 31 projects a fourth projection pattern (not shown in the figure) on the projection plane, the fourth projection pattern does not overlap with the second projection pattern, so as to reduce the heat transfer of the power supply circuit board 31 to the first sensor 12. Further, as shown in Figure 29 and Figure 30 , the mounting member 4 is a metal sheet member, and is clamped and fixed to the bottom shell 3. Since the mounting member 4 is installed against a wall surface, the temperature of the mounting member 4 is closer to the ambient temperature. The mounting member 4 projects a fifth projection pattern (not shown in the figure) on the projection plane, the second projection pattern is contained in the fifth projection pattern, so that the temperature detected by the first sensor 12 is closer to the ambient temperature.

[0192] In some embodiments, as shown in Figure 22- Figure 25 , the first sensor 12 is electrically connected to the control circuit board 13 through a first wire 121, and the first wire 121 is in a bent shape, so as to facilitate the first sensor 12 to be arranged at a corner of the panel shell 11.

[0193] In some embodiments, as shown in Figure 19 , Figure 20 , Figure 23 and Figure 26 , the temperature controller 100 further comprises a middle shell 19, the panel shell 11 covers the middle shell 19, and the first sensor 12 is arranged between the middle shell 19 and the panel shell 11. A heat insulation foam 151 is arranged beside the first sensor 12, and the heat insulation foam 151 is clamped between the panel shell 11 and the middle shell 19, and is used to block the heat transfer to the first sensor 12. Wherein, the side of the first sensor 12 can be understood as being close to the first sensor 12 and being arranged side by side with the first sensor 12. In this embodiment, as shown in Figure 23 and Figure 26 , the first sensor 12 is arranged at the lower right corner of the panel shell 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 the upper side and the left side are respectively provided with a heat insulation foam 151, which is used to block the heat transfer of the heat in the center of the panel shell 11 to the first sensor 12, and the heat insulation foam 151 can block a 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 insulation foam 151 is made of EVA die-cut material.

[0194] In some embodiments, as shown in Figure 26 and Figure 27As shown, the middle shell 19 and the panel shell 11 are provided with an isolation space 16 at the position corresponding to the first sensor 12, and the first sensor 12 is accommodated in the isolation space 16. The isolation space 16 can be understood as a containing space enclosed by the middle shell 19 and the panel shell 11, and the first sensor 12 is enclosed in the isolation space 16 to reduce the heat transfer from the center of the panel shell 11 to the first sensor 12. Further, the air vent hole 112 is communicated with the isolation space 16, so that the temperature and humidity in the isolation space 16 are closer to the ambient temperature and humidity.

[0195] In a specific embodiment, as shown in Figure 20 、 Figure 27 and Figure 26 , the panel shell 11 is provided with a first isolation rib 114, the middle shell 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 shell 19 and the inner wall of the panel shell 11 form the isolation space 16. The first wire 121 extends from the outside of the isolation space 16 into the inside of the isolation space 16, and the end of the first wire 121 close to the first sensor 12 is pressed and bent by the second isolation rib 191. The first wire 121 is pasted to the panel shell 11 at the position corresponding to the first sensor 12.

[0196] Further, as shown in Figure 20 and Figure 26 , the middle shell 19 is fixedly connected to the panel shell 11 by a plurality of connecting bolts 192, one of which 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 and making the positional relationship between the first sensor 12, the isolation space 16 and the heat insulation foam 151 more stable. The panel shell 11 is embedded with knurled nut columns 115 corresponding to the connecting bolts 192 at the positions corresponding to the connecting bolts 192. Before injection molding, the knurled nut columns 115 are placed in the mold of the panel shell 11, and then the panel shell 11 is injection molded, so that the knurled nut columns 115 are integrated with the panel shell 11.

[0197] Further, as shown in Figure 20 and Figure 19 , the middle shell 19 is configured as a quadrilateral, and the four corners of the middle shell 19 are fixedly connected to the panel shell 11 by the connecting bolts 192. As shown in Figure 20 and Figure 23As shown, the middle shell 19 is provided with a buckling position 193 on both sides, and the panel shell 11 is provided with buckling buckles 116 on both sides. When the middle shell 19 is installed on the panel shell 11, the buckling buckles 116 are buckled on the buckling positions 193 first, so that the middle shell 19 and the panel shell 11 are preliminarily fixed, and then the two are finally fixed through the connecting bolts 192.

[0198] One side of the control circuit board 13 facing the bottom shell 3 is provided with a pin header 131, and the middle shell 19 is provided with a pin header through hole 194 at the corresponding position of the pin header 131. The pin header 131 is inserted into the pin header 311 through the pin header through hole 194.

[0199] Further, as shown, Figure 18 As shown, the upper surface of the panel shell 11 is provided with a mounting groove 117, and the screen 14 is placed in the mounting groove 117. The back of the screen 14 is pasted to the mounting groove 117 by double-sided adhesive tape. The upper surface of the screen 14 is covered with a transparent cover plate 17. The transparent cover plate 17 is pasted to the panel shell 11 by double-sided adhesive tape, 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 abuts against the lower surface of the screen 14, and the other end abuts against the upper surface of the control circuit board 13. The conductive foam 152 is used to conduct static electricity on the screen 14 to the control circuit board 13, so as to prevent the screen 14 from being damaged by static electricity. In a preferred embodiment, the screen 14 is an LCD touch screen (which can be understood in the light of the related description of the above embodiment).

[0200] As shown, Figure 22 and Figure 18 The screen 14 is provided with a second wire 143, which is connected to the control circuit board 13 through the panel shell 11. The upper end of the control circuit board 13 is electrically connected with a proximity sensor 132 and two microphones 133, and the two microphones 133 are respectively located on both sides of the proximity sensor 132. As shown, Figure 18 The proximity sensor 132 is arranged on the side of the panel shell 11 away from the control circuit board 13, and the proximity sensor 132 is clamped between the transparent cover plate 17 and the panel shell 11. The proximity sensor 132 is connected to the control circuit board 13 through a third wire 1321, and the third wire 1321 passes through the panel shell 11. The proximity sensor 132 adopts a sensor with a model of LTR-X1503, which integrates the functions of illuminance detection and proximity sensing. The sensor can emit infrared light of a specified wavelength, and can detect whether an object is close to the thermostat 100 based on the principle of infrared light reflection. When the distance between the object and the thermostat 100 is less than a predetermined distance, the thermostat 100 controls the screen 14 to light up or switch the display content. As shown,Figure 22 As shown, the microphone 133 is arranged below the top wall of the panel shell 11, and the top wall of the panel shell 11 is provided with a sound guide hole 118 at a position opposite to each microphone 133.

[0201] As shown, Figure 22 and Figure 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 of 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 display content of the screen 14 and control the communication module 134 to send signals externally. The communication module 134 integrates Bluetooth and WIFI communication capabilities (2.4G), and the communication module 134 is electrically connected to a patch antenna 1341 which is pasted on the side wall of the panel shell 11 to avoid the signal of the communication module 134 being shielded by the screen 14 and the control circuit board 13. Further, the lower left corner and the upper right corner of the control circuit board 13 are fixedly connected to the panel shell 11 through circuit board bolts 136, and the panel shell 11 is embedded with knurled nut columns 115 corresponding to the circuit board bolts 136 at positions corresponding to the circuit board bolts 136, and the circuit board bolts 136 are connected to the knurled nut columns 115.

[0202] In some embodiments, as shown, Figure 26 The diameter of the air hole 112 is greater than 2mm to facilitate the air outside the panel shell 11 to enter the air hole 112, thereby improving the detection accuracy of the first sensor 12. In a specific embodiment, the air hole 112 is configured as a tapered hole with a small upper end and a large lower end, the diameter of the upper end is 3mm, and the diameter of the lower end is 3.1mm.

[0203] As shown, Figure 19 The bottom shell 3 is sleeved with a metal mounting member 4 around, the mounting member 4 is fixedly connected to the bottom shell 3, and the mounting member 4 is fixedly connected to the cassette 6 by long screws. Since the mounting member 4 has low rigidity and is easy to deform under the locking force of the long bolt 451, the bottom shell 3 will deform along with the mounting member 4, causing the position of the power supply circuit board 31 inside the bottom shell 3 to change. Since the power supply circuit board 31 is connected to the control circuit board 13 through the cooperation of the pin header 131 and the female header 311, the change in the position of the power supply circuit board 31 will cause the connection between the power supply circuit board 31 and the control circuit board 13 to fail. To solve the problem of easy deformation of the metal member and the bottom shell 3, in some embodiments, as shown, Figure 19 , Figure 28- Figure 30As shown, the temperature controller 100 comprises a panel assembly 1, a bottom shell 3, and a mounting member 4 arranged around the bottom shell 3, the mounting member 4 is separately formed with the bottom shell 3; wherein the mounting member 4 is provided with a mounting portion 41, the mounting portion 41 is configured to be connected to the socket 6 through a threaded connecting member 45, the bottom shell 3 is provided with a supporting portion 33 at the corresponding position of the mounting portion 41, the supporting portion 33 supports the second surface of the mounting portion 41, and the second surface is arranged as the surface of the mounting portion 41 facing away from the panel assembly 1. In the embodiment, the panel assembly 1 comprises the panel shell 11, the screen 14, the middle shell 19, the control circuit board 13, and the first sensor 12 as described above. The threaded connecting member 45 can be understood as a connecting member with threads, and in a preferred embodiment, the threaded connecting member 45 is a long bolt 451. The mounting portion 41 is provided with a through hole, so that the threaded connecting member 45 can pass through the mounting portion 41 and be connected to the socket 6.

[0204] As shown in Figure 30 , the socket 6 is configured as an open-ended box structure, the temperature controller 100 is put into the socket 6 from the open end of the socket 6, and the socket 6 is provided with connecting ears 61 inwardly arranged on the left and right sides respectively, the connecting ears 61 are provided with threaded holes, and the threaded connecting member 45 passes through the mounting portion 41 and is connected to the threaded holes, so as to fix the mounting member 4 to the socket 6. When the locking force of the threaded connecting member 45 is large, the mounting portion 41 will be deformed towards the connecting ears 61, thereby causing the entire mounting member 4 to be deformed. In the embodiment, the bottom shell 3 of the temperature controller 100 is provided with a supporting portion 33 at the position of the mounting portion 41, the supporting portion 33 supports the second surface of the mounting portion 41, and the second surface is the surface of the mounting portion 41 facing the connecting ears 61. When the locking force of the threaded connecting member 45 is large, the supporting portion 33 abuts against the second surface of the mounting portion 41, at this time, it is equivalent to that the bottom shell 3 and the mounting member 4 jointly resist the deformation of the mounting portion 41, which greatly improves the anti-deformation ability of the mounting portion 41, reduces the deformation amount of the mounting member 4 and the bottom shell 3, and further avoids the connection failure between the power circuit board 31 and the control circuit board 13.

[0205] As shown in Figure 28 and Figure 29 , the supporting portion 33 can be a buckle, a supporting rib, etc., and in a specific embodiment, the supporting portion 33 is configured as a supporting buckle, which is integrally formed with the bottom shell 3. It is worth mentioning that the supporting portion 33 adopts the supporting buckle so as to facilitate the mounting member 4 to be sleeved on the bottom shell 3 from the lower side of the bottom shell 3. In a specific embodiment, as shown in Figure 28 and Figure 29As shown, the bottom shell 3 is circumferentially provided 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 portions 34 abut the upper side of the mounting member 4, and the limiting buckles 35 are buckled to the lower side of the mounting member 4, so as to limit the mounting member 4. In a specific embodiment, the abutting portions 34 and the limiting buckles 35 are integrally formed on the bottom shell 3, the abutting portions 34 are configured as ribs protruding outward from the side of the bottom shell 3, the mounting member 4 is provided with an abutting port 42 at a position corresponding to the abutting portions 34, and the abutting portions 34 are embedded in the abutting port 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 as to facilitate the magnetic connection of the mounting member to the panel assembly 1.

[0206] In some embodiments, as shown in Figure 28- Figure 30 As shown, the mounting member 4 is provided with the mounting portions 41 on both sides, the mounting portions 41 are provided with mounting holes 411, and the threaded connecting members 45 are connected to the outside through the mounting holes 411; the mounting member 4 has a first surface facing the panel assembly 1, the mounting portions 41 are recessed in the first surface, and the recessed amount is less than 3 mm. Wherein, the recessing of the mounting portions 41 in the first surface is to accommodate the nuts of the threaded connecting members 45, so that the space occupied by the nuts in the panel assembly 1 is smaller, thereby reducing the thickness of the panel assembly 1. It is worth noting that the recessed amount of the mounting portions 41 is controlled to be less than 3 mm in this embodiment, so as to avoid the interference between the mounting portions 41 and the connecting ears 61 of the cassette 6.

[0207] It is worth noting that the separate forming of the mounting member 4 and the bottom shell 3 facilitates the use of different materials for the mounting member 4 and the bottom shell 3. In some embodiments, the mounting member 4 is made of iron material, the panel assembly 1 includes a permanent magnet 18, and the panel assembly 1 is magnetically connected to the mounting member 4 through the permanent magnet 18, so as to realize the quick disassembly and assembly between the panel assembly 1 and the bottom shell 3.

[0208] Further, the mounting member 4 is stamped and formed by iron sheet metal, and the mounting portions 41 are integrally formed on the mounting member 4.

[0209] Further, as shown in Figure 19As shown, the permanent magnet 18 is provided in plurality, and is 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 clamping site 1191. One end of the mounting member 4 is clamped to the clamping site 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 tongue 43 corresponding to the clamping site 1191, and the tongue 43 is upwardly bent towards the panel assembly 1. The tongue 43 is inserted into the clamping site 1191 to achieve clamping of the tongue 43 and the clamping site 1191. The mounting member 4 is provided with a suction part 44 corresponding to the permanent magnet 18, and the suction part 44 is integrally formed on the mounting member 4. When the panel assembly 1 is mounted on the mounting member 4, the second end is first moved close to the tongue 43, so that the tongue 43 is inserted into the clamping site 1191. Then, the first end is moved close to the suction part 44, so that the suction part 44 is attracted to the permanent magnet 18. Thus, the mounting is completed. When the panel assembly 1 is dismounted from the mounting member 4, the first end of the panel assembly 1 is first bent outwardly, so that the suction part 44 is separated from the permanent magnet 18. Then, the second end is moved to separate the tongue 43 from the clamping site 1191. Thus, the dismounting is completed. Compared with the traditional buckle connection, the panel assembly 1 of the present embodiment is connected by clamping at one end and magnetic attraction at the other end. Thus, the panel assembly 1 and the bottom shell 3 can be more quickly and conveniently mounted and dismounted.

[0210] Further, as shown in Figure 21 and Figure 20 the top wall of the panel shell 11 is downwardly provided with a magnet limiting groove 1192, and the magnet limiting groove 1192 is sized to be suitable for the permanent magnet 18. The magnet limiting groove 1192 is open downwardly, and the permanent magnet 18 is loaded from the lower side of the magnet limiting groove 1192. The side of the magnet limiting groove 1192 facing the bottom shell 3 is provided with two limiting ribs 1193, and the limiting ribs 1193 abut against the side of the permanent magnet 18 facing the bottom shell 3, so as to block movement of the permanent magnet 18 towards the bottom shell 3. The middle shell 19 is provided with a magnet accommodating groove 195 corresponding to the magnet limiting groove 1192. When the middle shell 19 is buckled to the panel shell 11, the magnet accommodating groove 195 contains the magnet limiting groove 1192, and the magnet accommodating groove 195 abuts against the lower surface of the permanent magnet 18, so as to limit the permanent magnet 18 in the magnet limiting groove 1192. The two limiting ribs 1193 are respectively located at the left and right sides of the permanent magnet 18. When the permanent magnet 18 is attracted to the suction part 44 of the mounting member 4, the suction part 44 is located between the two limiting ribs 1193.

[0211] Further, as shown in Figure 29 and Figure 31As shown, the isolation plate 5 is fixedly connected to the bottom shell 3, and the side surface of the isolation plate 5 abuts against the inner wall of the bottom shell 3, so that the rigidity of the isolation plate 5 to the bottom shell 3 is enhanced, thereby preventing the bottom shell 3 from being deformed and avoiding the position of the power supply circuit board 31 inside the bottom shell 3 from being changed greatly.

[0212] In a specific embodiment, as shown in Figure 31 As shown, the bottom shell 3 is configured as a box structure with an open top, the isolation plate 5 is arranged on the open side of the bottom shell 3, the bottom shell 3 extends upward to form three connecting columns 36, and the isolation plate 5 is fixedly connected to the connecting columns 36 by self-tapping screws 51. The power supply circuit board 31 is provided with a through hole at a position corresponding to each self-tapping screw 51, and the self-tapping screw 51 is connected to the connecting column 36 through the through hole.

[0213] The air conditioner commonly used in decoration at present includes a protocol type fluorine machine central air conditioner (hereinafter referred to as a fluorine machine air conditioner) and a fan coil type central air conditioner. In some embodiments, the temperature controller 100 can control the fan coil type central air conditioner to operate. The fan coil type central air conditioner generally includes an air conditioner host, a water pump, an air conditioner water valve, a water flow pipeline and a fan coil. The air conditioner host is used to heat or cool water. The water pump is used to drive the water to circulate and flow, so that the heated or cooled water flows through the water flow pipeline, the air conditioner water valve and the fan coil, and finally flows back to the air conditioner host. The air conditioner water valve is used to control the water flow in the fan coil. The fan coil blows the heat or cold in the water into the room, so that the indoor temperature rises or falls. The temperature controller 100 provided by the utility model can be connected to the fan coil type central air conditioner. The temperature controller 100 controls the opening and closing of the air conditioner water valve and the air volume of the fan coil to achieve the purpose of controlling the room temperature. In a specific embodiment, as shown in Figure 32The power circuit board 31 is viewed from the top and bottom after being flipped up and down. At the bottom of the power circuit board 31 are a terminal block 312, three single-pole single-throw relays 313, and one single-pole double-throw relay 314. The terminal block 312 has seven wiring holes. The first and second wiring holes are connected to the neutral and live wires, respectively. The third wiring hole is connected to the high-speed port of the fan coil unit, the fourth wiring hole is connected to the medium-speed port of the fan coil unit, and the fifth wiring hole is connected to the low-speed port of the fan coil unit. The three single-pole single-throw relays 313 are electrically connected to the third, fourth, and fifth wiring holes, respectively, to control the fan coil unit to switch between high, medium, and low speeds. The sixth wiring hole is connected to the closed port of the air conditioning water valve, and the seventh wiring hole is connected to the open port of the air conditioning water valve. The single-pole double-throw relay 314 is electrically connected to the sixth and seventh wiring holes, to control the opening and closing of the air conditioning water valve.

[0214] It is worth noting that the thermostat 100 provided in this embodiment can only control the opening and closing of the air conditioning water valve and the air volume of the fan coil unit. When the air conditioner needs to switch between cooling and heating modes, the user needs to operate the air conditioning unit to switch. Since the thermostat 100 in this embodiment only contains one single-pole double-throw relay 314, it can only control one air conditioning water valve. Therefore, this embodiment is suitable for two-pipe fan coil central air conditioning. 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 and can be applied to four-pipe fan coil central air conditioning.

[0215] In some embodiments, the thermostat 100 can control the operation of the underfloor heating and the fresh air system. In a specific embodiment, such as... Figure 32 As shown, the bottom of the power circuit board 31 is provided with a terminal block 312, three single-pole single-throw relays 313, and one single-pole double-throw relay 314. The terminal block 312 has seven wiring holes, wherein the first and second wiring holes are connected to the neutral wire and the live wire, respectively; the third wiring hole is connected to the high fan speed port of the fresh air unit, the fourth wiring hole is connected to the medium fan speed port of the fresh air unit, and the fifth wiring hole is connected to the low fan speed port of the fresh air unit. The three single-pole single-throw relays 313 are electrically connected to the third, fourth, and fifth wiring holes, respectively, for controlling the fresh air unit to switch between high, medium, and low speeds; the sixth wiring hole is connected to the closed port of the underfloor heating water valve, and the seventh wiring hole is connected to the open port of the underfloor heating water valve. The single-pole double-throw relay 314 is electrically connected to the sixth and seventh wiring holes, for controlling the opening and closing of the underfloor heating water valve.

[0216] The existing fluorine machine air conditioner is provided with a control port connected to a central controller, and the central controller sends a control instruction to control the fluorine machine air conditioner to run. Since the data conversion standards of fluorine machine air conditioners of different brands are different, the existing temperature controller is difficult to adapt to fluorine machine air conditioners of multiple brands. Moreover, the control instruction is transmitted by weak current, and the existing temperature controller generally sets the weak current board in the panel shell and sets the strong current board in the bottom shell. Since the temperature controller needs to be wired inside the dark box, the weak current board cannot be directly connected to the communication wire, which brings inconvenience to wiring. In order to enable the temperature controller 100 provided by the utility model to control fluorine machine air conditioners of various brands and facilitate the connection of communication wires, in some embodiments, as shown in Figure 32 The bottom shell 3 is internally provided with the power circuit board 31 and the communication circuit board 315, the communication circuit board 315 is electrically connected to the power circuit board 31, the power circuit board 31 carries a strong current circuit (a strong current power conversion circuit, a relay, etc.), and the communication circuit board 315 carries a weak current circuit.
