Description

[0001] This invention application is a divisional application based on the Chinese patent application with patent number 202411056223X submitted by the applicant on August 2, 2024, and patent name “A Indoor Environment Conditioning and Control System”.

Technical field

[0002] The present invention belongs to the field of smart home technology, and in particular relates to smart environment adjustment and control technology. [Background Technology]

[0003] With the rapid development of the economy, smart home technology has become ubiquitous in every household. However, current smart home systems are unable to accurately understand the human body's environmental needs, resulting in a lack of intelligence. Current smart home control systems can only allow owners to manually adjust the indoor environment by remotely turning on the air conditioner or ventilation system before returning home. They are unable to adjust the indoor environment based on the real-time state of the human body.

[0004] In existing technology, human vital signs can be regularly monitored using sensors built into some smart sports wearable devices. However, the accuracy of electronic sensing is often insufficient or can be affected by environmental factors (such as water damage). Furthermore, wearing or purchasing a separate electronic product is expensive and limited to long-term use by a single user, making it inaccurate. [Summary of the invention]

[0005] In view of the shortcomings of the existing technology, the technical problem to be solved by the present invention is to provide an indoor environment adjustment and control system that can detect the human body status and body sensation in the indoor environment in real time, and with the help of existing indoor environment adjustment equipment, adjust the current indoor environment according to the real-time status of the human body.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] An indoor environment adjustment and control system includes indoor environment adjustment equipment and an intelligent environment adjustment and control device installed in different indoor areas, 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. The indoor environment adjustment and control system also includes 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 somatosensory signs and feeds back the detection information to the intelligent environment adjustment and control device, wherein the intelligent environment adjustment and control device obtains the environmental needs of the human body based on the human body posture and somatosensory signs and controls the indoor environment adjustment equipment to realize dynamic environmental adjustment needs, wherein the millimeter-wave radar sensor is coupled to a control circuit of a fan carrier device, and the fan carrier device is provided with a processing unit, wherein the processing unit is used to process the human body posture and / or somatosensory sign information collected by the millimeter-wave radar sensor, and the intelligent environment adjustment and control device is connected to the hidden fresh air system via wires hidden in the building wall or electrically connected to the air conditioning system via a bus, and processes various operating rules and collected data through an interface.

[0008] Preferably, the intelligent environment adjustment and control device is provided with an environment detection processing module, which is an auxiliary device of a gateway device, a single-chip device or a cloud server. The processing logic of the environment detection processing module includes:

[0009] Process the collected millimeter-wave radar sensor data;

[0010] Based on the point map of the collected millimeter-wave radar sensor data, the current human body posture and the changes in the detected somatosensory characteristics are judged, and the current environmental needs of the human body are determined accordingly;

[0011] Control the working status of indoor environment adjustment equipment according to environmental requirements.

[0012] 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 environmental adjustment carrier device and an indoor environmental adjustment device protocol to achieve local communication.

[0013] Preferably, the intelligent environmental conditioning and control device is configured to utilize a cloud processor to collaboratively perform synchronous and phased analysis on the collected environmental or vital sign data to optimize and identify the data.

[0014] Preferably, the intelligent environmental conditioning control device is a fresh air controller installed in the wall of a building.

[0015] Preferably, the fresh air controller is provided with:

[0016] A base is installed and fixed in the wall of a building. The back side of the base is provided with multiple connection ports for connecting the building wires. The base has a cover plate that is snapped together to form a cavity for accommodating a transformer power supply. The DC output terminal of the transformer power supply is passed through the interface provided on the cover plate.

[0017] an accessible panel secured to the front surface of the base, the panel comprising keys and an adjacent display; and

[0018] The temperature and humidity sensors are aligned with the holes on the outer edges of the panel housing to detect environmental data.

[0019] Preferably, the indoor environment adjustment and control system communicates with a smart home control system, and after the smart environment adjustment and control device determines the human body's environmental needs, it controls the corresponding indoor environment adjustment equipment through the smart home control system.

[0020] The present invention adopts the above technical solution and has the following beneficial effects:

[0021] Millimeter-wave radar sensors use the FMCW frequency modulation continuous wave principle. Higher-frequency millimeter-wave radars achieve greater precision and can detect subtler movements. Typically, 24GHz millimeter-wave radars can detect human motion and chest movement during still breathing, while 60GHz millimeter-wave radars can detect both motion and stillness (breathing, chest movement, and heartbeats).

[0022] Therefore, within the adjustable dynamic operating range (20GHz-65GHz), the millimeter-wave radar sensor can support posture detection of the human body within its measurable range, including but not limited to detecting the human body's standing, sitting, lying, falling, etc.; in addition, it can also detect a user's body gestures (such as waving, shaking, etc.) in a normal sitting or lying state.

[0023] 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.

[0024] 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.

[0025] In particular, the millimeter-wave radar sensor is coupled to the control circuit of the fan carrier equipment, including but not limited to fans, fresh air equipment, air-conditioning equipment, etc. Since the fan 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 somatosensory signs.

[0026] 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. The intelligent environment adjustment and control device is connected to the hidden fresh air system through wires hidden in the building wall or is electrically connected to the air-conditioning system through a bus. The interface processes various operating rules and collected data. 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.

[0027] The intelligent environmental adjustment and control device derives real-time environmental requirements based on the real-time human body status and body sensation in the indoor environment, and the indoor environmental adjustment equipment is controlled to achieve the environmental requirements, thereby adjusting the current indoor environment according to the real-time status of the human body to achieve dynamic environmental adjustment requirements.

[0028] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[Specific implementation method]

[0039] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0040] Those skilled in the art will appreciate that, unless there is any conflict, the features in the following embodiments and implementations may be combined with each other.

[0041] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. For example, terms such as "upper," "lower," "front," and "rear" that indicate orientation or positional relationships are based solely on the orientation or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the disclosure. They do not indicate or imply that the device or component referred to must have a specific orientation or be constructed or operated in a specific orientation. Therefore, they should not be construed as limiting the disclosure.

Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0043] In the present invention, the terms "installation", "fixation", "connection", "limitation", "movement" and the like should be understood in a broad sense. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0045] 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. 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. 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. The millimeter-wave radar sensor 11 detects human body posture and somatosensory signs, and feeds back the detection information to the intelligent environment adjustment and control device. The intelligent environment adjustment and control device obtains the environmental needs of the human body based on the human body posture and somatosensory signs, and controls the indoor environment adjustment equipment to achieve the environmental needs.

[0046] Referring to existing technologies, millimeter-wave radar sensors use the FMCW frequency-modulated continuous wave principle. Higher-frequency millimeter-wave radars achieve greater precision and can detect subtler movements. Typically, 24GHz millimeter-wave radars can detect human motion and chest movement during still breathing, while 60GHz millimeter-wave radars can detect both motion and stillness (breathing, chest movement, and heartbeats).

[0047] Therefore, within 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.

[0048] Figures 1 to 3As 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 (20GHz-65GHz). For example, the posture of a human body includes Figure 6 The millimeter-wave radar sensor 11 can detect the standing and sitting postures (i.e., whether the user is standing or sitting for a long time) more accurately and adjust the mechanical movements of some components of the ceiling fan light. In addition, the millimeter-wave radar sensor 11 can detect the user's gestures (such as waving, shaking, etc.) in a normal sitting or lying state.

[0049] When the human body is in a relatively static state, the body sense detection includes but is not limited to the body sense state 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.

[0050] 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.

[0051] 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 fan carrier device or on multiple fan carrier devices. Since the indoor environment conditioning carrier device is facing all human bodies indoors 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 high detection accuracy when detecting human body posture and somatosensory signs.

[0052] In addition, the millimeter-wave radar sensor detects the human body's posture and physical signs and feeds the detection information back to the intelligent environmental control device. Therefore, the intelligent environmental control device can analyze the human body's environmental needs based on the detection information, i.e., the human body's posture, physical signs, and physical signs, including but not limited to heating / cooling, dehumidification, fresh air, or negative ion purification. In the prior art, intelligent environmental control devices mainly rely on traditional sensors to detect the environment, analyze the human body's environmental needs, and control indoor environmental control equipment to meet these environmental needs. However, they do 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 environmental control device derives the real-time environmental needs based on the real-time human state and physical sense in the indoor environment. The indoor environmental control equipment is controlled to meet these environmental needs, thereby adjusting the current indoor environmental conditions according to the real-time state of the human body.

[0053] For example, if the environment is hot, the heart rate will be slightly faster. Conversely, if the environment or weather is cold, the heart rate will be slower. Therefore, if the heart rate is detected to be greater than the set value, it can be known that the environment needs to cool down, so the air conditioning system can be controlled to lower the set temperature. If the heart rate is detected to be less than the set value, it can be known that the environment needs to warm up, so the indoor environment conditioning equipment can be controlled to increase the set temperature.

[0054] 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 the human body's breathing rate is detected to be 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 perform dehumidification.

[0055] For example, if a user leaves the room, the indoor environment adjustment device can be turned off. If a user enters the room, the indoor environment adjustment device can be turned on. Another example is that if the user sits or lies down for a long time, the temperature can be raised appropriately.

[0056] The indoor environment adjustment device can also be controlled according to human gestures (such as waving, shaking, etc.), for example, waving represents turning on the indoor environment adjustment device.

[0057] It is understood that indoor environment conditioning equipment is not limited to air conditioning systems and fresh air systems, and may also include, for example, floor heating equipment, air purification equipment, etc. The air conditioning system and fresh air system may be provided separately or integrated into the air conditioning system. The air conditioning system may be a single air conditioner 2 (equipment) or comprised of multiple air conditioners (equipment). The fresh air system may be a single fresh air fan 21 (equipment) or comprised of multiple fresh air fans (equipment).

[0058] It is understood that other environmental sensors can also be installed indoors to collect indoor environmental data, such as temperature sensors, humidity sensors, and PM2.5 sensors. The intelligent environmental control device can also combine human body data collected by the millimeter-wave radar sensor and environmental data collected by the surrounding environmental sensors to comprehensively determine the human body's current environmental needs, including but not limited to the need for cooling, heating, or air purification. For example, if the temperature sensor detects that the ambient temperature is higher than the human body's optimum temperature, and the millimeter-wave radar sensor detects that the human heart rate is greater than the set value, it can be determined that the environmental need is heating, and 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 human body's optimum humidity, and the millimeter-wave radar sensor detects that the human breathing rate is greater than the set value, it can be determined that the environmental need is dehumidification, and the indoor environmental control equipment can be controlled to perform dehumidification. If the PM2.5 sensor detects that the indoor PM2.5 level exceeds the standard, it can be determined that the environmental need is air purification, and the indoor environmental control equipment can be controlled to perform fresh air or negative ion purification.

[0059] Figure 1 An exemplary embodiment of the present invention is depicted. At least some major electrical components of a conditioning control system within an indoor environment 100 are depicted. However, the millimeter-wave radar sensor that supports detection of user vital signs in the current indoor environment is not specifically shown; instead, it is primarily embedded in an indoor environment conditioning carrier device, such as a fan carrier device.

[0060] In this embodiment, the "fan carrier device" refers to an air convection device containing a mechanical fan, fan blades and an integrated motor hub and / or similar principles, such as generating air flow through heat exchange, pressure or vibration. In terms of the relevant issues to be solved by the present invention, the fan carrier device can take 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 actual air volume of the indoor environment 100. Figure 2 —6. Furthermore, 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 molecules with the flowing air.

[0061] For example, the fan carrier can be designed to be concealed or wall-mounted, not facing indoor users. However, this may not provide the same air purification effect as the present embodiment. While the concealed fan and blades are aesthetically pleasing and easy to install, their airflow relies solely on the free diffusion of air from the fan's surface outlet, resulting in less than ideal results. Furthermore, the millimeter-wave radar sensor 11 itself requires installation space, but the existing smart fan device cannot be overcrowded, so the bladed fan shown in the figure is used.

[0062] 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 fan blade rotation 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 as uniform light output 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.

[0063] Preferably, the millimeter-wave radar sensor 11 is installed in the control circuit of the smart ceiling fan 1, which serves as the fan carrier. This allows the radar sensor to be placed in a relatively stable and wide-range sensing position. The control circuit includes a processing unit that processes the human body posture and somatosensory information collected by the millimeter-wave radar sensor.

[0064] In the current indoor environment 100 scenario, the intelligent environmental conditioning control device serves as the central device of the entire indoor environment conditioning 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 conditioning equipment, such as air-conditioning systems and fresh air systems.

[0065] The intelligent environmental control device may be an intelligent air conditioning controller, an intelligent fresh air controller, an ambient temperature and humidity panel, a PM2.5 detection sensor, etc. The intelligent environmental control device may also be built into any wall-mounted panel or coupled to an integrated circuit of an intelligent wall switch.

[0066] It is understood that the intelligent environmental control device forms a network with the indoor environmental control carrier device and the indoor environmental control device to achieve communication, preferably wireless communication. In this way, the intelligent environmental control device can obtain detection information from the millimeter-wave radar sensor of the indoor environmental control carrier device through wireless communication and can also control the indoor environmental control device.

[0067] 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 an effective sensing position at a closer distance.

[0068] 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.

[0069] Furthermore, when the microcontroller module within the ceiling fan lamp 1 serves as a core component of the aforementioned intelligent environmental control device, the microcontroller module is configured to parse, convert, and transmit networking functions for various protocol-based data from external environmental sensors, thereby enabling device automation linkage with various fresh air devices in the current environment 100, thereby facilitating information and sensor data coupling and sharing between household devices in the current scenario. The microprocessor module within the ceiling fan lamp 1 is also configured as a fan carrier device equipped with a processing unit for collecting, processing, and computing environmental and / or vital information continuously collected from other environmental sensors (except for the radar sensor 11).

[0070] Generally, the intelligent environment conditioning and control device includes an integrated computing device consisting of 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 devices, and the operating status of microcontrollers in various home appliances such as air conditioners, fresh air, etc. through a serial interface.

[0071] The intelligent environmental control device includes an environmental detection and processing module, which can be a gateway device, a single-chip microcomputer device, or a cloud server. The processing logic of the environmental detection and processing module includes: processing and analyzing collected millimeter-wave radar sensor data; determining the current human body state based on a point map of the collected millimeter-wave data; and detecting changes in breathing and heart rate to determine whether the human body is in a state requiring cooling or in a normal state. Combined with the body's big data, the module can more accurately obtain the user's environmental needs.

[0072] The processing logic in the processing module unit also includes processing and controlling the indoor environment adjustment equipment in the home, such as controlling the working status of air conditioning, fresh air, etc. after obtaining the analyzed environmental requirements.

[0073] The intelligent environmental control device can also use a cloud processor (cloud server) as an auxiliary device to periodically process comprehensive data related to the current environment 100. For example, the environmental control 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 within the system (including protocol data parsing) can comprehensively judge the current environmental needs of the human body (need for heating / cooling, dehumidification, or negative ion purification) based on the human body data collected by the millimeter wave radar sensor and the environmental data collected by the surrounding environment sensor.

[0074] Here, use Figure 2 The illustrated embodiments are used to describe how to couple sensory data with vital sign data. Figure 2 The schematic environment 100 shows a living room scene, for example, with different height spatial areas, including a high spatial area 110 and a low spatial area 120, and each area has a measured environmental parameter with a different value by default. The high spatial 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 spatial area 120 and there are multiple of them, and they are located in different positions of the current living room so that they can be easily reached by people. Because under normal circumstances, it is after a person enters the environment 100 that he or she 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 effect of automatic adjustment, the ceiling fan lamp 1 is configured to automatically adjust the environmental parameters when there is no user present, that is, the air adjustment in the current environment 100 does not depend on whether there is a user. Therefore, the system does not require the user to be present indoors to trigger a series of automatic linkage functions.

[0075] according to Figure 7As shown, an improved fresh air controller 4 includes a base 47 mounted on a building wall. The back of the base is provided with multiple wiring ports 472 for connecting to building electrical wiring (including neutral / live wires, RS485 control bus, and other twisted pair cables). The base 47 has a cover 48 that snaps together to form a cavity 471 for accommodating a transformer power supply (not shown). The DC output terminals of the transformer power supply extend through ports 481 provided on the cover 48.

[0076] This type of fresh air controller 4 also includes a user-accessible panel fixed to the front surface of the aforementioned base 47. This panel comprises a housing 43 and a matching backplate 46. In one embodiment, the width or height of the housing 43 is significantly greater than the outer edge 473 of the base 47 to better position the temperature and humidity sensor module for optimal operational efficiency. In another embodiment, the housing 43 has a layered structure 432 to support (e.g., flushly mount) and secure the various electronic components.

[0077] A button 41 and a display 42 built into the structure next to the button 41, 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 area near it. The temperature and humidity sensor is coupled to the communication control module to calculate and transmit the sensed temperature value to the micro-control 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 than / 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.

[0078] The interface 481 can be designed to have a relatively large protruding profile, and the corresponding mating interface 461 on the back panel 46 can also be designed to have a distinct groove to achieve a larger contact surface for plug-in fixation. Preferably, it can also be achieved by cooperating with the additional latching teeth arranged side by side and the multiple latching grooves 474 provided on the outer edge 473 to achieve a snap-on fixation. This is because the portion of the panel that significantly extends beyond the base 47 must be completely sealed, and the base 47 is usually a standard size that is not easy to expand. Therefore, the excess portion of the panel must fit tightly against the building surface without gaps to meet standard requirements, so this connection mechanism is adopted.

[0079] Based on the above embodiment, the back side of the circuit substrate 45 is also provided with a connection 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 (or 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 to be opposite to each other on the outer edge to achieve higher collection efficiency, such as achieving air convection rather than free diffusion of air.

[0080] The daughter board 44 is also provided with a microcontroller 442 to communicate with the coupled 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 wireless communication function, serving 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 set 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 tactile feel, the hole 434 can be clamped with a buffering elastic member such as a silicone sheet. In addition, the button 41 is fixed in the clamping rib 435 to fix its starting position.

[0081] The back of the layered structure 432 is equipped with a receiving step and fasteners (e.g., studs) to secure the circuit board 45 and sub-board 46. The front side also features a fixed step for embedding the display 42 module and keypad 41, ensuring that the display and keypad surfaces are flush with the housing 43. In a real-world installation, the display 42 is typically a liquid crystal display panel, such as an LCD. Therefore, a bracket 433 is also provided within the layered structure 432 to support the display panel and prevent damage. Although the figure shows a disassembled structure, when fully assembled and installed on a building wall, the LCD panel may be subject to stress transmitted by mounting screws and fasteners. This is the purpose of the layered structure 432 to support the LCD panel. Sometimes, the LCD panel's signal cables are also routed to the circuit board 451 through holes 434. Preferably, if the display 42 has touch functionality, a graphics processor is also incorporated into the circuit board 45, which is also communicatively coupled to the microcontroller 442 to transmit touch information.

[0082] After sensing information that exceeds the threshold, the temperature and humidity sensor 441 transmits it to the above-mentioned micro-control module through the wireless network to start device linkage. As an optimization solution, 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 lamp 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 lamp 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).

[0083] 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 blower 21 are also set to directional air delivery toward the area where the ceiling fan lamp 1 is located as much as possible. Figure 2 In the scenario shown in FIG. 1 , 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 activation of any environmental replacement equipment with such built-in environmental sensors, 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 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. 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. Moreover, the wind direction adjustment setting mode is, for example, to send air in the direction of the ceiling fan light 1 60% of the time.

[0084] In addition, part of the air flow sent by the air conditioner 2 also flows to other parts of 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 a constant temperature has been 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 opposite direction R1 to achieve Figure 2 In the scene shown in the figure below, the indoor air is actively extracted to the high space area 110 by the upward spiral 204. During the above air flow supply (104, 204) event, the air replacement efficiency of the current indoor environment 100 is significantly improved.

[0085] In some cases, when, for example, a constant temperature condition occurs, the above-mentioned environmental adjustment event is terminated (including the generation of logs and execution time periods on the cloud server, etc.), and is only generated and started again when any environmental sensor parameter exceeds / falls below the threshold again. 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 turn on only some of the 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 direction and start the blade 12 to rotate according to the preset wind speed.

[0086] When a user spends a long time in environment 100, environmental adjustment events may change. One implementation involves high-frequency detection of vital signs, such as those on the human skin, to determine whether the user is sitting or lying still or working (e.g., sitting or lying for an extended period while still moving their limbs). Alternatively, the user can determine whether to continue executing environmental adjustment events based on vital sign data from mobile device 7. Sometimes, the user may not be wearing mobile device 7 (e.g., a smartwatch). The millimeter-wave radar sensor 11 can detect and determine whether the user's limbs are waving during directional detection, thereby executing corresponding preset control instructions. Figure 8 An example of an application process supporting a ceiling fan 1 (including a driver engine for executing the aforementioned environmental adjustment event) is provided. This application process can also present operational functional components on the display 31 of the thermostat 3 or the display 42 of the aforementioned fresh air blower 4. In this document, using the fresh air blower 4 as an example execution medium, interface 710 is considered an initial interface that presents guidance on the operational functions of each related device. 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 interface 711, as well as the environmental parameter values sensed by the temperature and humidity sensor 441. In addition, interface 710 also includes a display section 712 that displays power parameters detected by the connected bus to facilitate determining the required device power (or power factor) setting in the aforementioned environmental adjustment event. Preferably, after the driver engine for the environmental adjustment event is written to the fresh air controller 4, a display interface 713 can also be presented for its manual activation mode, indicating whether the current system has enabled this automated process. The displays of interfaces 710 and / or 720 can also be presented on the mobile device 7 accordingly.

[0087] like Figure 8As shown, in the sub-interface 720, the system log generation rules of this automated process are described. This is to facilitate the user to view more intuitively, and on the other hand, it is reported to the cloud server through the above-mentioned micro-control module as a protocol instruction transfer to determine the execution process and efficiency of the current event. In the example of the environmental adjustment event, the user can set "waving his arm" as an execution condition, just like Figure 3 As shown, when the outdoor environment data from the mobile device 7 is transmitted to the microcontroller module, it can be used as a composite execution condition. For example, if the outdoor ambient temperature is higher than the set temperature, such as 29 degrees Celsius, the "waving arm" condition is met, and if the outdoor ambient temperature is higher than 29 degrees Celsius, the smart cleaning mode is executed. At the same time, during the device linkage process, certain electrical devices (such as external human body sensors) also determine other conditions (such as "no movement for 2 minutes") before determining to activate the millimeter-wave radar sensor 11. This avoids false triggering and reduces the power consumption of the millimeter-wave radar sensor 11.

[0088] in addition, Figure 4 and Figure 5 Shown compared Figure 1 Different ceiling fan lamp structures have fan assembly 912 arranged on the lower side of lamp body 15. Blades 12 are driven to rotate by brushless DC motor 914 on the upper side. In order to prevent the blades from affecting and interfering with the millimeter-wave radar module, millimeter-wave radar sensor 11 is installed below blade 12. Here, the antenna of 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 blades above. Among them, millimeter-wave radar sensor 11 is arranged in the rotation center area of blade 12 and rotates synchronously with the blade or is stationary relative to the blade. In the example shown in the figure, 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 electromagnetic waves emitted by millimeter-wave radar sensor 11 is circumferentially limited, the sensing range of millimeter-wave radar sensor 11 can be expanded by rotating the millimeter-wave radar module. Of course, millimeter-wave radar sensor 11 can also be stationary relative to the blade. In this case, the direction of electromagnetic waves emitted by millimeter-wave radar sensor 11 can be downward without restriction.

[0089] 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.

[0090] like Figure 5 As shown, Figure 4Compared to the illustrated embodiment, the ceiling fan lamp 1 can be designed as an assembly, with a wider range of designs depending on the illumination requirements of the light source within the lamp body 15. The assembly can then comprise multiple ceiling fan lamps, for example, two side-by-side. Alternatively, the assembly can incorporate the aforementioned microcontroller module within only one ceiling fan lamp, while the other ceiling fan lamps serve merely as cooperating actuators. This means that multiple ceiling fan lamps 1 are controlled in series by a single microcontroller module.

[0091] 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.

[0092] 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.

[0093] The above description is merely a specific embodiment of the invention, but the scope of protection of the invention is not limited thereto. Those skilled in the art will understand that the invention includes, but is not limited to, the drawings and the contents described in the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the invention are intended to be included within the scope of the claims.
