Description

[Technical field]

[0001] The present invention belongs to the field of smart home technology, and in particular relates to smart environment adjustment and control technology. [Background technology]

[0002] With the rapid development of economy, smart home industry has become popular in every household, but the current smart home system cannot accurately obtain the environmental needs of human body, which makes smart home not intelligent. The current smart home control system can only realize that the owner can manually turn on the air conditioner or fresh air system in the house to adjust the indoor environment before returning home, but cannot adjust the current indoor environment according to the real-time status of human body.

[0003] In the prior art, human vital signs data can be monitored regularly through sensors built into some smart sports wearable devices. However, on the one hand, the accuracy of electronic product sensing is obviously insufficient or inaccurate due to environmental factors (such as water stains). On the other hand, it is more expensive to wear or buy an electronic product alone, and it is not universal if only one user uses it for a long time. [Summary of the invention]

[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide an indoor environment adjustment and control system that can detect the state and body sensation of a human body in the indoor environment in real time, and adjust the current indoor environment according to the real-time state of the human body.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions: an indoor environment adjustment and control system, comprising indoor environment adjustment equipment and an intelligent environment adjustment and control device, wherein the indoor environment adjustment equipment comprises an air conditioning system for adjusting the indoor temperature and a fresh air system for adjusting the indoor air quality, and the indoor environment adjustment and control system also comprises an indoor environment adjustment carrier device equipped with at least one millimeter-wave radar sensor, wherein the millimeter-wave radar sensor detects human body posture and body sense signs, and feeds back the detection information to the intelligent environment adjustment and control device, and the intelligent environment adjustment and control device obtains the environmental needs of the human body according to the human body posture and body sense signs, and controls the indoor environment adjustment equipment to achieve the environmental needs.

[0006] Preferably, the millimeter wave radar sensor is installed on a wind turbine carrier device.

[0007] Preferably, the fan carrier device is a fan light equipped with a millimeter-wave radar sensor; and / or, the millimeter-wave radar sensor is arranged in a control circuit of the fan carrier device.

[0008] Preferably, the fan carrier device is provided with a processing unit, and the processing unit is used to process the human body posture and body sense sign information collected by the millimeter wave radar sensor.

[0009] Preferably, the body posture includes standing, sitting, lying, falling, and gestures in normal sitting and lying states; the somatosensory signs include the human heart rate, breathing rate, and whether the user enters / leaves the venue.

[0010] Preferably, the environmental requirements include temperature increase / dehumidification, fresh air or negative ion purification.

[0011] Preferably, the intelligent environmental adjustment and control device includes an intelligent air conditioning controller and / or an intelligent fresh air controller and / or an environmental temperature and humidity panel and / or a PM2.5 detection sensor device; or, the intelligent environmental adjustment and control device is built into a wall-mounted panel or coupled to an integrated circuit of an intelligent wall switch; and / or, the intelligent environmental adjustment and control device is networked with an indoor environment adjustment carrier device and an indoor environment adjustment device protocol to achieve mutual communication.

[0012] Preferably, the intelligent environment adjustment and control device is provided with an environment detection and processing module, and the environment detection and processing module is a gateway device or a single-chip microcomputer device, or a cloud server in the cloud.

[0013] Preferably, the processing logic of the environment detection processing module includes:

[0014] Process the collected millimeter wave radar sensor data;

[0015] According to the point map of the collected millimeter-wave radar sensor data, the current human body posture and the detected changes in body sense characteristics are judged, and the current environmental needs of the human body are judged accordingly;

[0016] Control the working status of indoor environment adjustment equipment according to environmental requirements.

[0017] Preferably, the indoor environment adjustment and control system communicates with a smart home control system, and after the smart environment adjustment and control device obtains the environmental requirements of the human body, it controls the corresponding indoor environment adjustment equipment through the smart home control system.

[0018] The present invention adopts the above technical solution and has the following beneficial effects:

[0019] Millimeter wave radar sensors use the FMCW frequency modulation continuous wave principle. The higher the frequency, the higher the accuracy of the millimeter wave radar, and the more subtle the movement can be detected. Usually, 24GHz millimeter wave radar can detect human body movement, still breathing and chest rise and fall, while 60GHz millimeter wave radar can detect human body movement and stillness (breathing, chest rise and fall, heartbeat).

[0020] Therefore, within the adjustable dynamic operating range (20GHz-65GHz) of the millimeter-wave radar sensor, it can support posture detection of the human body within its measurable range, including but not limited to detection of the human body's standing, sitting, lying, falling and other states; in addition, it can also detect a user's gestures (such as waving, shaking, etc.) in a normal sitting or lying state.

[0021] In addition, the somatosensory detection includes but is not limited to the human heart rate, human breathing rate and other somatosensory states; in the low detection state, the sensor is used to detect whether the user enters / leaves the venue.

[0022] Therefore, millimeter-wave radar sensors are used to detect human body posture and physical signs, and the detection accuracy is higher than that of conventional electronic products.

[0023] In particular, the millimeter-wave radar sensor is installed on the indoor environment conditioning carrier equipment, such as fan carrier equipment, including but not limited to fans, fresh air equipment, air-conditioning equipment, etc. Since the indoor environment conditioning carrier equipment is facing all human bodies in the room in order to adjust the indoor environment, the millimeter-wave radar sensor can be placed in a relatively stable and wide-range sensing position, which is not only universal, but also has high detection accuracy when detecting human body posture and body sensory signs.

[0024] In addition, the millimeter-wave radar sensor detects the human body shape and physical signs and feeds back the detection information to the intelligent environment adjustment and control device. Therefore, the intelligent environment adjustment and control device can analyze the human body's environmental needs in a targeted manner based on the detection information, that is, the human body shape and physical signs, including but not limited to heating / cooling, dehumidification, fresh air or negative ion purification.

[0025] The intelligent environment adjustment and control device obtains the real-time environmental demand according to the real-time human state and body sensation in the indoor environment, and the indoor environment adjustment equipment is controlled to realize the environmental demand, so that the current indoor environment can be adjusted according to the real-time state of the human body.

[0026] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[Specific implementation method]

[0037] The technical solutions of the embodiments of the present invention are explained and described below in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0038] Those skilled in the art will appreciate that, in the absence of conflict, the features in the following embodiments and implementations may be combined with each other.

[0039] The terms used in the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. For example, the words "upper", "lower", "front", "back" and the like indicating orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0040] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0041] In the present invention, the terms "installation", "fixation", "connection", "limitation", "movement" and the like should be understood in a broad sense. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0043] like Figures 1 to 8 As shown, the present invention provides an indoor environment adjustment and control system, including indoor environment adjustment equipment and an intelligent environment adjustment and control device, wherein the indoor environment adjustment equipment includes an air conditioning system for adjusting the indoor temperature and a fresh air system for adjusting the indoor air quality, and the indoor environment adjustment and control system also includes an indoor environment adjustment carrier device equipped with at least one millimeter wave radar sensor 11, wherein the millimeter wave radar sensor 11 detects human body posture and body sense signs, and feeds back the detection information to the intelligent environment adjustment and control device, and the intelligent environment adjustment and control device obtains the environmental needs of the human body according to the human body posture and body sense signs, and controls the indoor environment adjustment equipment to achieve the environmental needs.

[0044] Referring to the existing technology, millimeter wave radar sensors use the FMCW frequency modulation continuous wave principle. The higher the frequency of the millimeter wave radar, the higher the accuracy and the more subtle the movement can be detected. Usually, 24GHz millimeter wave radar can detect human body movement, still breathing and chest rise and fall, while 60GHz millimeter wave radar can detect human body movement and stillness (breathing, chest rise and fall, heartbeat).

[0045] Therefore, under the adjustable dynamic operating range (20GHz-65GHz), the millimeter-wave radar sensor can support posture detection and body sensing detection of the human body within its measurable range.

[0046] Figures 1 to 3 As shown, the millimeter wave radar sensor 11 is configured to detect the posture of a human body within its measurable radiation range area 8 under an adjustable dynamic working range (20 GHz-65 GHz). For example, the posture of a human body includes Figure 6 The standing posture and sitting posture (i.e., whether standing or sitting for a long time) shown in the smart ceiling fan light can be more accurately sensed and the mechanical actions of some parts of the ceiling fan light can be set and adjusted. Moreover, the millimeter wave radar sensor 11 can be used to more deeply sense whether the human body is in a lying or falling state. In addition, in the high-frequency state, the gestures of the current user's body (such as waving, shaking, etc.) are detected when the user is sitting or lying normally.

[0047] When the human body is in a relatively static state, the body sensing detection includes but is not limited to the body sensing states such as the human heart rate and the human breathing rate. Figure 2 As shown, in the low detection state, the millimeter wave radar sensor 11 is used to detect whether the user enters / leaves the venue.

[0048] Therefore, millimeter-wave radar sensors are used to detect human body posture and physical signs, and the detection accuracy is higher than that of conventional electronic products.

[0049] In particular, the millimeter-wave radar sensor is installed on an indoor environment conditioning carrier device, such as a fan carrier device, including but not limited to fans, fresh air equipment, air-conditioning equipment, etc. It can be installed on one of the fan carrier devices or on multiple fan carrier devices. Since the indoor environment conditioning carrier device is facing all human bodies in the room in order to adjust the indoor environment, especially the fan carrier device is set closer to the human body, the millimeter-wave radar sensor can be placed in a relatively stable and wide-range sensing position, which is not only universal, but also has a high detection accuracy when detecting human body posture and somatosensory signs.

[0050] In addition, after the millimeter wave radar sensor detects the human body posture and body sense signs, it will feed back the detection information to the intelligent environment adjustment and control device, so that the intelligent environment adjustment and control device can analyze the human body's environmental needs in a targeted manner based on the detection information, that is, the human body posture, body sense signs, including but not limited to heating / cooling, dehumidification, fresh air or negative ion purification, etc. In the prior art, the intelligent environment adjustment and control device mainly relies on traditional sensors to detect the environment, analyze the human body's environmental needs, and control the indoor environment adjustment equipment to achieve the environmental needs, but relatively speaking, it does not directly detect the human body. In the technical solution of this embodiment, the millimeter wave radar sensor directly detects the human body, and the intelligent environment adjustment and control device obtains the real-time environmental needs based on the real-time human body state and body sense in the indoor environment, and controls the indoor environment adjustment equipment to achieve the environmental needs, so that the current indoor environment can be adjusted according to the real-time state of the human body.

[0051] For example, if the environment is hot, the heart rate will be slightly faster, and vice versa, if the environment or weather is cold, the heart rate will be slower. Therefore, if the human heart rate is detected to be greater than the set value, it can be known that the environmental demand is cooling, so the air conditioning system can be controlled to lower the set temperature. If the human heart rate is detected to be less than the set value, it can be known that the environmental demand is heating, so the indoor environment adjustment device can be controlled to increase the set temperature.

[0052] For example, if the humidity is too high, the human body will feel weak, chest tightness, and the breathing rate will be faster. Therefore, if it is detected that the human body's breathing rate is greater than the set value, it can be known that the environmental demand is dehumidification, so the indoor environment conditioning equipment can be controlled to dehumidify.

[0053] For example, if the user is detected to be leaving, the indoor environment adjustment device can be controlled to be turned off. If the user is detected to be entering, the indoor environment adjustment device can be controlled to be turned on. For another example, if the user sits or lies for a long time, the temperature can be appropriately raised.

[0054] The indoor environment regulating device can also be controlled according to human gestures (such as waving, shaking, etc.), for example, waving represents turning on the indoor environment regulating device.

[0055] It is understandable that the indoor environment adjustment equipment is not limited to the air conditioning system and the fresh air system, and may also be, for example, floor heating equipment, air purification equipment, etc. The air conditioning system and the fresh air system may be separately arranged or integrated into the air conditioning system, the air conditioning system may be one air conditioner 2 (equipment) or may be composed of multiple air conditioners (equipment), and the fresh air system may be one fresh air fan 21 (equipment) or may be composed of multiple fresh air fans (equipment).

[0056] It is understandable that other environmental sensors can be installed indoors to collect indoor environmental data, such as temperature sensors, humidity sensors, and PM2.5 sensors. The intelligent environmental adjustment and control device can also combine the human body data collected by the millimeter wave radar sensor and the environmental data collected by the surrounding environment sensor to comprehensively judge the current environmental needs of the human body, including but not limited to the need to cool down, heat up, or purify the air. For example, if the temperature sensor detects that the ambient temperature is higher than the suitable temperature for the human body, and the millimeter wave radar sensor detects that the human heart rate is greater than the set value, it can be known that the environmental demand is to heat up, so the air conditioning system can be controlled to increase the set temperature; for example, if the humidity sensor detects that the ambient humidity is higher than the suitable humidity for the human body, and the millimeter wave radar sensor detects that the human breathing rate is greater than the set value, it can be known that the environmental demand is dehumidification, so the indoor environmental adjustment equipment can be controlled to dehumidify. If the PM2.5 sensor detects that the PM2.5 in the indoor environment exceeds the standard, it can be known that the environmental demand is to purify the air, so the indoor environmental adjustment equipment can be controlled to perform fresh air or negative ion purification operations.

[0057] Figure 1 An embodiment of the present invention is exemplarily depicted, wherein at least some main electrical components of the conditioning control system installed in the indoor environment 100 are depicted, while the millimeter wave radar sensor supporting the detection of the user's vital sign parameters in the current indoor environment is not specifically embodied, but is mainly built into the indoor environment conditioning carrier device, such as the fan carrier device.

[0058] The "fan carrier device" referred to in this embodiment mainly refers to air convection devices containing mechanical fans, fan blades and integrated motor hubs and / or similar principles, such as generating air flow through heat exchange, pressure or vibration. In terms of the related problems to be solved by the present invention, the fan carrier device can be in various forms, Figure 4 and Figure 5 The solution shown is to use a DC motor 914 to drive the blades 12 to rotate, so that a better air flow effect can be achieved according to the volume of air in the actual indoor environment 100. Figure 2 —6 is more vividly reflected. In addition, the fan carrier device can also be equipped with other components, such as a small negative ion purifier, a temperature and humidity sensor or a fragrance volatilization module to further diffuse the relevant action molecules with the flowing air.

[0059] For example, the fan carrier can also be designed to be hidden or wall-mounted and not facing indoor users, but the effect may not be as good as the air purification effect in this embodiment. Although the hidden fan and blades are beautiful in appearance and easy to install, their air outlet effect only relies on the free diffusion of the air outlet on the surface of the fan, and the effect is not ideal. In addition, the millimeter wave radar sensor 11 itself also requires installation space, but the internal space of the original smart fan device cannot be too crowded, so the blade fan shown in the figure is used.

[0060] like Figures 1 to 3 As shown, in one embodiment, the fan carrier device is a fan lamp equipped with a millimeter-wave radar sensor, preferably, a ceiling fan lamp 1. The ceiling fan lamp includes a fan assembly and a lamp body installed together, and the millimeter-wave radar sensor is installed on the lamp body, wherein the lamp body includes a lamp board and a light source assembly, and the lamp board can be set as an integrated structure and is made of metal (such as an aluminum substrate), and the millimeter-wave radar sensor is installed below the lamp board. The lamp board isolates the millimeter-wave radar sensor from the fan assembly above, and the signal of the rotation of the fan blades can be shielded by the metal lamp board. Preferably, the millimeter-wave radar sensor is installed at a central position below the lamp board to balance the sensing range as much as possible. At the same time, the light source assembly is coaxially arranged with the millimeter-wave radar module to achieve uniform light output as much as possible. For example, the light source assembly is arranged radially outside the millimeter-wave radar module and surrounds the millimeter-wave radar module to avoid the millimeter-wave radar module affecting the light output of the light source.

[0061] Preferably, the millimeter wave radar sensor 11 is installed in the control circuit of the intelligent ceiling fan lamp 1 as a fan carrier device. In this way, the radar sensor can be placed in a more stable and wide range sensing position. A processing unit is provided in the control circuit, and the processing unit is used to process the human body posture and body sense information collected by the millimeter wave radar sensor.

[0062] In the current indoor environment 100 scenario, the intelligent environmental adjustment and control device serves as the central device of the entire indoor environment adjustment and control system, supports intelligent control or linkage control, and is used to send, receive, control or linkage control the current indoor fixed-installed indoor environment adjustment equipment, such as air-conditioning systems and fresh air systems.

[0063] The intelligent environment adjustment control device may be an intelligent air conditioning controller, an intelligent fresh air controller, an environmental temperature and humidity panel, a PM2.5 detection sensor, etc. The intelligent environment adjustment control device may also be built into any wall-mounted panel or coupled to an integrated circuit of an intelligent wall switch.

[0064] It is understandable that the intelligent environment adjustment control device is networked with the indoor environment adjustment carrier device and the indoor environment adjustment device protocol to achieve mutual communication, preferably wireless communication. In this way, the intelligent environment adjustment control device can obtain the detection information of the millimeter wave radar sensor from the indoor environment adjustment carrier device through wireless communication, and can also control the indoor environment adjustment device.

[0065] Preferably, when the intelligent environmental conditioning control device selects a fresh air controller 4, such as an intelligent fresh air controller. The sensing data of the above-mentioned millimeter wave radar sensor 11 is stored in the microcontroller module in the ceiling fan lamp 1 and local calculation is performed. In addition, the local calculation also includes sending the device linkage instruction to the fresh air controller 4 in the current environment 100. In the building electrical facilities, the fresh air controller 4 is connected to the hidden fresh air fan 21 (group) through wires hidden in the wall, or is electrically connected to the air conditioner 2 through a bus (the air conditioner is sometimes installed in a similar position to the fresh air unit). Although the air conditioner in the prior art has a built-in temperature sensor, as an improvement in this article, the temperature and humidity sensor is built into the panel of the fresh air controller 4 as a closer effective sensing position.

[0066] In some embodiments, a semi-fixed, environmental sensor temperature and humidity panel 5 (including temperature and humidity sensors, PM2.5 detection sensor devices, etc.) can also be used as an auxiliary and control device for environmental detection. Figure 1 In this way, especially when a built-in fresh air fan is selected, the millimeter wave radar sensor 11 is combined with a variety of environmental sensor settings to achieve better ventilation efficiency.

[0067] In addition, when the microcontroller module in the ceiling fan lamp 1 is used as a core component of the above-mentioned intelligent environment adjustment control device, the microcontroller module is configured to parse, convert and convey networking functions of different protocol data from external environmental sensors, so as to be able to generate equipment automation function linkage with various fresh air equipment in the current environment 100, so as to facilitate information and sensor data coupling and sharing between home appliances in the current scene. Among them, the built-in microprocessor module of the ceiling fan lamp 1 is also configured as a fan carrier device with a processing unit for collecting, processing and calculating environmental and / or vital information continuously collected from other environmental sensors (except the radar sensor 11).

[0068] Typically, the intelligent environmental conditioning control device includes an integrated computing device including an ARM unit with processing capabilities and a core processing unit (including a CPU), which can process various sensors, fresh air, the operating rules and collected data of equipment and devices, and the operating status of microcontrollers in various household appliances such as air conditioners, fresh air, etc. through a serial interface.

[0069] The intelligent environment adjustment and control device is provided with an environment detection processing module, which is a gateway device or a single-chip device, or a cloud server in the cloud, etc. The processing logic of the environment detection processing module includes: processing and analyzing the collected millimeter wave radar sensor data, judging the current human body state according to the point map of the collected millimeter wave data, and detecting whether the current human body is in a state of needing to cool down or in a normal state by detecting changes in breathing and heart rate, and combining the big data of the human body to more accurately obtain the environmental needs of the user.

[0070] The processing logic in the processing module unit also includes processing and controlling indoor environmental adjustment equipment in the home, such as controlling the working status of air conditioning, fresh air, etc. after obtaining the analyzed environmental requirements.

[0071] The intelligent environment adjustment and control device can also use a cloud processor (cloud server) as an auxiliary device to process the comprehensive data related to the current environment 100 in stages. For example, the environment adjustment device is configured to use the cloud processor to collaboratively synchronize and periodically analyze the collected data to optimize and identify the data. Preferably, the local logic processing (including protocol data analysis) within the system can comprehensively judge the current environmental needs of the human body (need to increase / lower temperature, dehumidify or purify negative ions) based on the human body data collected by the millimeter wave radar sensor and the environmental data collected by the surrounding environment sensor.

[0072] Here, use Figure 2 The illustrated embodiments are used to describe how to couple the sensor data with the vital sign data. Figure 2 The schematic environment 100 shows a living room scene, for example, with different height space areas, including a high space area 110 and a low space area 120, and each area has a measured environmental parameter with a different value by default. The high space area 110 includes a ceiling fan lamp 1 installed on the ceiling of the building, and the fresh air controller 4 as an environmental adjustment device can be set in the low space area 120 and there are multiple of them, and located in different positions of the current living room so that they can be easily reached by human hands. Because under normal circumstances, it is after the human body enters the environment 100 that it feels that the air is not comfortable enough and then actively turns on the electrical equipment related to environmental adjustment. However, in order to achieve the automatic adjustment effect, the ceiling fan lamp 1 is configured to automatically adjust the environmental parameters when there is no user, that is, the air adjustment in the current environment 100 does not depend on whether the user exists. Therefore, the system does not require the user to be indoors to trigger a series of automatic linkage functions.

[0073] according to Figure 7As shown, an improved fresh air controller 4 is provided with a base 47 installed and fixed in the wall of the building, and a plurality of connection ports 472 are provided on the back side of the base to connect the building wires (including neutral / live wires, RS485 control bus and other twisted pairs). The base 47 has a cover plate 48 to buckle to form a cavity 471 for accommodating a transformer power supply (not shown), and the DC output terminal of the transformer power supply passes through the interface 481 provided on the cover plate 48.

[0074] This type of fresh air controller 4 also includes a panel for user access, which is fixed to the front surface of the base 47. The panel has a housing 43 and a matching back plate 46. In one embodiment, the width or height of the housing 43 is significantly greater than the outer edge 473 of the base 47, so as to better position the temperature and humidity sensor module specifically to achieve better operating efficiency. In another embodiment, the housing 43 has a layered structure 432 to support (e.g., flushly inlay) and fix various electronic components.

[0075] A button 41 and a display 42 built next to the button 41 structure, and a temperature and humidity sensor 441 is relatively independently provided on the inner surface of the fresh air controller 4 to sense the real-time temperature value of the surrounding area. The temperature and humidity sensor is coupled to the communication control module to calculate and transmit the sensed temperature value to the microcontroller module in the ceiling fan lamp 1. In this way, although the fresh air controller 4 is also connected to the fresh air fan 21 through the building wires, at this time the fresh air controller 4 will not trigger the fresh air fan 21 or the air conditioner 2 to start or cut off the power simply because the measured temperature value is lower / higher than a certain value, thereby achieving more accurate execution of the sensing action of the environmental parameters. Therefore, the size of the back panel 46 is also significantly larger than the outer edge 473, and the figure exemplarily depicts a shell structure that grows significantly upward.

[0076] The interface 481 can be designed to have a relatively large protruding outer profile, and the corresponding matching interface 461 provided on the back plate 46 can also be designed to have a significant groove to achieve a larger contact surface for plug-in fixation. Preferably, the additional latching teeth arranged side by side and the multiple latching grooves 474 provided on the outer edge 473 can also be used to achieve a snap-in fixation. This is because the panel has a significantly larger size than the base 47 and needs to be completely sealed, and the base 47 is usually a standard size that is not convenient for expansion. Therefore, the extra part of the panel needs to be close to the building surface without gaps to meet standard requirements, so such a connection mechanism is adopted.

[0077] Based on the above embodiments, the back side of the circuit substrate 45 is also provided with a wiring terminal (shielded) that matches the above-mentioned transformer power supply to realize power supply and signal transmission (such as the air conditioner load on the control bus mentioned above). The circuit substrate 45 includes a circuit sub-board 44 used as a sensor module, and the two boards are connected and fixed by a signal cable 443. As a major improvement, the relatively independent sub-board 44 is dedicated to the layout of the sensor module, and the temperature and humidity sensor 441 (it can also be other types of environmental sensor elements) is as close as possible to the inner edge of the above-mentioned layered structure 432 on the back of the shell 43, and the outer edge of the shell 43 is provided with a hole 431 to align the temperature and humidity sensor 441. In one embodiment, the hole 431 can be arranged at opposite positions on the outer edge to achieve higher collection efficiency, such as achieving air convection rather than free diffusion of air.

[0078] A microcontroller 442 is also provided on the daughter board 44 to communicate with the coupling sensor 441 and is connected to the signal processing circuit on the circuit substrate 45 through the flat cable 443. The microcontroller 442 can also be an integrated circuit with a wireless communication function, as the above-mentioned communication control module. In one embodiment, the button 41 of the panel is made into a rebound electronic switch, and the piezoelectric module 451 of the electronic switch is arranged on the circuit substrate 45. A mechanical contact is provided on the back side of the button 41 to reach the piezoelectric module 451 through the hole 434, and sometimes in order to achieve a better touch, the hole 434 can be clamped with a buffer elastic member such as a silicone sheet. In addition, the button 41 is clamped in the clamp 435 to fix its starting position.

[0079] The back side of the layered structure 432 is provided with a receiving step and a clamp (such as a stud) to fix the position of the circuit substrate 45 and the sub-board 46. The front side is also preset with a fixed step to embed the display 42 module and the button 41, and make the display and the button surface flush with the housing 43. In the actual installation process, the display 42 is usually a piece of liquid crystal plate such as an LCD, so a bracket 433 is also provided in the layered structure 432 to support the display plate to prevent damage, because although the figure shows a disassembled structure, when it is integrated and fully installed on the building wall, the liquid crystal plate may be subjected to stress transmitted by, for example, mounting screws, clamps, etc., which is also the effect of using the layered structure 432 to support the liquid crystal plate. Sometimes, the signal cable of the liquid crystal plate is also led out to the circuit substrate 451 through the hole 434. Preferably, if the display 42 has a touch function, a graphics processor is also added to the circuit substrate 45, and it is also communicatively coupled to the microcontroller 442 to transmit touch information.

[0080] After sensing information exceeding the threshold, the temperature and humidity sensor 441 transmits the information to the above-mentioned micro-control module through the wireless network to start the device linkage. As an optimization scheme, the millimeter wave radar sensor 11 is configured to continuously and directionally detect human body or environmental parameters to determine whether to start the micro-control module to generate an environmental adjustment event. One implementation scheme is to start the corresponding controlled device, such as the blades 12 of the ceiling fan 1, the intelligent air conditioner 2 and / or the fresh air fan 21, through the control system listed in this article. Among them, the ceiling fan 1 has a brushless DC motor that can rotate at different speeds and in the direction R1 (or reverse) and the blades 12 coupled thereto. The environmental adjustment parameters include environmental parameters in different areas of the environment 100, and the sensing coefficient is obtained through the above-mentioned temperature and humidity sensor 441 or other types of sensors (such as an air purification device including an environmental sensor).

[0081] When the blades 12 of the ceiling fan lamp 1 rotate according to the set value according to the environmental adjustment event represented by the sensor coefficient, the fan blades of the air conditioner 2 or the fresh air fan 21 are also set to deliver air as much as possible toward the area where the ceiling fan lamp 1 is located. Figure 2 Such a scene is shown in the figure, where the fresh air flow is mainly sent to the low space area 120 through the active rotary sinking 104 of the blades 12, and the environmental sensor in the environmental sensor temperature and humidity panel 5 simultaneously senses the air quality to determine the synchronous opening of any environmental replacement equipment with such environmental sensors built in, such as air purification devices and filters. In one embodiment, the environmental adjustment event includes the estimated time required to reach the preset environmental parameter value after the blades 12 are turned on and the types of various devices that are operated in conjunction. For example, the microcontroller module sends a control instruction to the fresh air controller 4 to which the device address of the air conditioner 2 to be controlled belongs, and the microcontroller 442 determines the power adjustment, wind direction and / or wind speed for the air conditioner to perform cooling / heating according to the control instruction, and the wind direction adjustment setting mode is, for example, 60% of the time to send air in the direction of the ceiling fan light 1.

[0082] In addition, part of the air flow sent by the air conditioner 2 also flows to other places in the environment 100 through passive free diffusion 102. Therefore, the fresh air controller 4 is configured to periodically send temperature and humidity sensing information to the micro-control module during the environmental adjustment event to determine whether the constant temperature is reached. In this case, if multiple environmental sensors sense that the environmental parameters have reached a constant, sometimes the micro-control module is also configured to control the blades 12 to rotate in the reverse direction R1 to achieve Figure 2 In the scene shown in the figure below, the indoor air is actively swirled up 204 and extracted to the high space area 110. During the above airflow supply (104, 204), the air replacement efficiency of the current indoor environment 100 is significantly improved.

[0083] In some cases, when, for example, a constant temperature condition occurs, the above environmental adjustment event is terminated (including generating logs and executing a duration period on the cloud server, etc.), and is only started again when any environmental sensing parameter exceeds / falls below the threshold. Figure 2 It also shows that when someone is present, the user's mobile device 7 can be connected to the cloud server to access the above micro-control module, and prompt the mobile device 7 "Is the environment comfortable?" and receive the user's response to this request. Sometimes, the user may still feel hot, so the micro-control module is configured to only turn on some electrical devices, for example, only according to Figure 4 In this way, the DC motor 914 is controlled to turn the blade module to the user's position and start the blade 12 to rotate according to the preset wind speed.

[0084] When the user stays in the environment 100 for a long time, the environmental adjustment event will change accordingly. One implementation is to detect the physical signs of the human skin in a high-frequency state, for example, to determine whether the user is sitting or lying quietly or in an office state (for example, the limbs are moving but sitting or lying for a long time), and it can also be determined whether to continue to run the environmental adjustment event based on the physical sign data of the mobile device 7. Sometimes, the user does not use the mobile device 7 (such as a smart watch) that he wears, and the millimeter wave radar sensor 11 can sense and determine that the user's limbs are waving during the directional detection process, thereby executing the corresponding preset control instructions. Figure 8 An example of an application process (including a driving engine for executing the above-mentioned environmental adjustment event) supporting a ceiling fan lamp 1 is given. The application process can also present an operable functional part on the display 31 of the thermostat 3 or the display 42 of the above-mentioned fresh air blower 4. In this article, the fresh air blower 4 is taken as an example as an execution carrier, and the interface 710 is considered to be an initial interface to present the operable function guide of each related device. The interface 710 of the fresh air controller 4 is used to display the setting parameters of the fresh air blower or air conditioner connected to the interface 711, and to display the environmental parameter values ​​sensed by the temperature and humidity sensor 441. In addition, the interface 710 also includes a display section 712 that uses the power parameters detected by the connected bus to facilitate determining the required device power (or power factor) in the above-mentioned environmental adjustment event. Preferably, after the driving engine of the environmental adjustment event is written into the fresh air controller 4, the display interface 713 can also be presented for its manual start mode, that is, to inform the current system whether to start this automatic process. The display of the above-mentioned interface 710 and / or 720 can also be presented accordingly on the mobile device 7.

[0085] like Figure 8As shown, in the sub-interface 720, the generation rules of the system log as this automated process are depicted. On the one hand, this is convenient for users to view more intuitively, and on the other hand, the micro-control module mentioned above, which is used as a protocol instruction transfer, reports to the cloud server to determine the execution process and efficiency of the current event. In the example of the environmental adjustment event, the user can be set to "wave his arms" as an execution condition, just like Figure 3 As shown, when the outdoor environment data of the mobile device 7 is transmitted to the microcontroller module, it can be used as a composite execution condition, such as the outdoor environment temperature is higher than the set temperature, such as 29 degrees Celsius, which satisfies the "waving arms" condition and the outdoor environment temperature is higher than 29 degrees Celsius, which means the smart cleaning mode is executed. At the same time, during the device linkage process, some other conditions (such as "no one moves for 2 minutes") are also determined by some electrical devices (such as external human body sensors) to determine whether to turn on the millimeter wave radar sensor 11, thereby avoiding false triggering and reducing the power consumption of the millimeter wave radar sensor 11.

[0086] in addition, Figure 4 and Figure 5 Shown compared to Figure 1 Different ceiling fan lamp structures, the fan assembly 912 is arranged on the lower side of the lamp body 15. The blades 12 are driven to rotate by the brushless DC motor 914 on the upper side. In order to avoid the influence and interference of the blades on the millimeter-wave radar module, the millimeter-wave radar sensor 11 is installed below the blades 12. Here, the antenna of the millimeter-wave radar sensor 11 is positioned downward, and electromagnetic waves are emitted in a direction downward, so that it will not be affected by the rotation of the upper blades. Among them, the millimeter-wave radar sensor 11 is arranged in the rotation center area of ​​the blade 12 and rotates synchronously with the blade or is stationary relative to the blade. In the example shown in the figure, the millimeter-wave radar sensor 11 is fixed to the rotation center of the blade and rotates synchronously with the blade. For the case where the direction of the electromagnetic waves emitted by the millimeter-wave radar sensor 11 is circumferentially limited, the sensing range of the millimeter-wave radar sensor 11 can be expanded by rotating the millimeter-wave radar module. Of course, the millimeter-wave radar sensor 11 can also be stationary relative to the blade. At this time, the direction of the electromagnetic waves emitted by the millimeter-wave radar sensor 11 can be unrestricted downward.

[0087] In addition, during the overall installation, the millimeter wave radar sensor 11 can also be fixed in the housing 213, and the housing 213 and the blades 12 can be fixed to completely fit the fan assembly.

[0088] like Figure 5 As shown, Figure 4Compared with the embodiment shown in the figure, the ceiling fan lamp 1 can be designed as an assembly, and the illumination of the light source in the lamp body 15 needs to be designed to be wider. Then the assembly has multiple ceiling fan lamps, for example, two side-by-side ceiling fan lamps. Sometimes, the assembly can only install the above-mentioned micro-control module in one ceiling fan lamp and the other ceiling fan lamps only serve as the actuator cooperating therewith, that is, multiple ceiling fan lamps 1 are controlled in series by one micro-control module.

[0089] like Figure 6 As shown, referring to the steering function of the blades in the prior art, in order to allow the blades to perform axial movements more conveniently toward the human body, the brushless DC motor 914 and the blades 12 can be more directionally aligned with the direction of the user, and at this time the millimeter wave radar sensor 11 also senses toward the human body accordingly.

[0090] Of course, it is understandable that the specific form of the ceiling fan lamp in the present invention can also be selected according to the situation of the building ceiling 70.

[0091] The above is only a specific embodiment of the invention, but the protection scope of the invention is not limited thereto. Those skilled in the art should understand that the invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the invention will be included in the scope of the claims.
