[0030] Please also see Figures 1 to 8 , the present invention provides a preferred embodiment of an air conditioning control system.

[0031] In some preferred embodiments of the present invention, Figure 1 and Figure 2As shown, the present invention provides an air conditioning control system, which is suitable for air conditioning that supports infrared control, a radar that detects indoor temperature and humidity in real time and whether someone is moving in the room, and automatically controls the air conditioning. Specifically, the air conditioning control system includes: an air conditioning control device 1, a server 2 and a mobile terminal 3, and the server 2 is connected to the air conditioning control device 1 and the mobile terminal 3 through a network.

[0032] The air conditioning control device 1 includes: a step-down module 100, a radar module 200, a sensor module 300, a microcontroller module 400, an infrared control module 500 and a communication module 600; wherein one end of the step-down module 100 is connected to a power supply voltage VCC_5V, and the other end of the step-down module 100 is respectively connected to the sensor module 300, the microcontroller module 400 and the infrared control module 500, for converting the power supply voltage VCC_5V into a first working voltage; the radar module 200 is used to collect personnel information in the space and generate personnel collection information accordingly; the sensor module 300 is used to collect environmental information in the space and generate environmental collection information accordingly; the microcontroller module 400 is respectively connected to the radar module 200 and the infrared control module 500; The sensor module 300 is connected to compare the personnel collected information with the preset personnel information, and to compare the environment collected information with the preset environment information, and to determine whether to turn on the air conditioner according to the comparison result, and output the judgment result; if the personnel collected information is equal to the preset personnel information, and the environment collected information matches the preset environment information, it is determined that the air conditioner needs to be turned on, otherwise it is determined that the air conditioner does not need to be turned on; the infrared control module 500 is connected to the micro-control module 400, and is used to output a control signal according to the judgment result. If the air conditioner needs to be turned on, the infrared control module 500 outputs a first control signal, otherwise the infrared control module 500 outputs a second control signal; the communication module 600 is connected to the micro-control module 400, and is used to communicate data with external devices.

[0033] The air conditioning control device 1 can be set on the side wall of the indoor space. For example, the installation height range of the air conditioning control device 1 is 1.8-2.2 meters, and the depression angle is 5-10°, ensuring that the internal radar module 200 can cover the ground activity range. The air conditioning control device 1 judges whether the air conditioning needs to be turned on based on the personnel signal and the environmental collection information. The personnel collection information output by the radar module 200 is the number of people detected in the space at the current moment, and the preset personnel information is a pre-set personnel threshold. When the personnel collection information, that is, the number of people in the space at the current moment is greater than the personnel threshold, there is a need to turn on the air conditioning. When there is someone in the space, the radar module 200 detects the action in the space and determines that there is someone in the space, then the personnel collection information outputs the current number of people in the space. On the contrary, if it is determined that there is no one in the space, the personnel collection information is 0. For example, the preset personnel information can be set to 0, and the air conditioning is turned on once there is someone in the space.

[0034] At the same time, exemplarily, the environmental information obtained by the sensor module 300 for collecting environmental information may be the temperature and humidity in the space at the current moment, and the preset environmental information is the preset temperature and humidity information. When the environmental collection information falls within the range of the preset environmental information, it means that the space environment is comfortable enough for the personnel and does not need to be adjusted by turning on the air conditioner; otherwise, when the environmental collection information does not match the preset environmental information, it means that the space environment is not comfortable for the personnel and the air conditioner needs to be turned on. When the personnel collection information matches the preset personnel information and the environmental collection information matches the preset environmental information, there are people in the space and the space environment is not comfortable enough for the personnel, then an infrared signal is output to turn on the air conditioner in the space; otherwise, the air conditioning control device 1 determines that there is no one in the space and it is determined that the air conditioning does not need to be turned on; or there are people in the space, but the environmental collection information shows that the space environment is comfortable at this time, then the air conditioning control device 1 also determines that the air conditioning does not need to be turned on. The infrared control module 500 receives the corresponding judgment result and outputs a control signal to control the opening or closing of the air conditioner accordingly.

[0035] At the same time, the air conditioning control device 1 transmits the personnel information, environmental collection information, etc. in the current space to the server 2 through the network. The user can view the status information of the air conditioner through the mobile device, and can also remotely control the opening and closing of the air conditioner through the mobile terminal 3. The mobile terminal 3 can be a mobile phone, a notebook, a tablet computer or a wearable device. Furthermore, a device management control application can be set on the server 2. The device management control application will send an energy-saving strategy to the communication module 600 based on the current personnel information and environmental collection information, and then control the air conditioning equipment by transmitting a control signal through the infrared control module 500. For example, the energy-saving strategy can be to control the air conditioner to be turned off after a delay of 5 minutes when no person is detected, or to control the air conditioner to be turned off when the temperature is lower than 22 degrees. The specific implementation method is not described here.

[0036] In a further implementation of some preferred embodiments of the present invention, Figure 3As shown, the communication module 600 includes a wired communication circuit 610; the wired communication circuit 610 is connected to the micro-control module 400, and the wired communication circuit 610 includes: a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a sixth resistor R6, a first capacitor C1, a first Schottky diode D1, a second Schottky diode D2, a first field effect transistor Q1, a serial bus connector (not shown in the figure) and a communication chip U1; wherein the source of the first field effect transistor Q1 is connected to the buck module 100, and the first field The gate of the field effect transistor Q1 is connected to one end of the first resistor R1, the drain of the first field effect transistor Q1 is respectively connected to the second end of the communication chip U1, the third end of the communication chip U1 and one end of the second resistor R2, and the other end of the second resistor R2 is grounded; the first end of the communication chip U1, the other end of the first resistor R1 and the fourth end of the communication chip U1 are respectively connected to the micro control module 400; the fifth end of the communication chip U1 is grounded, and the sixth end of the communication chip U1 is respectively connected to one end of the third resistor R3, the sixth resistor R6 one end of the third resistor R3 is connected to the buck module 100, and the other end of the sixth resistor R6 is connected to the cathode of the second Schottky diode D2; the seventh end of the communication chip U1 is respectively connected to one end of the fourth resistor R4 and one end of the fifth resistor R5, the other end of the fourth resistor R4 is grounded, and the other end of the fifth resistor R5 is connected to the cathode of the first Schottky diode D1; the eighth end of the communication chip U1 is connected to one end of the first capacitor C1 and the common end of the buck module 100; the serial bus connection The first end of the device is connected to the power supply voltage VCC_5V, the second end of the serial bus connector is connected to the cathode of the first Schottky diode D1 and the common end of the fifth resistor R5, the third end of the serial bus connector is connected to the cathode of the second Schottky diode D2 and the common end of the fifth resistor R5, the fourth end of the serial bus connector is connected to the micro-control module 400, and the fifth end of the serial bus connector is grounded; the other end of the first capacitor C1, the anode of the first Schottky diode D1 and the anode of the second Schottky diode D2 are grounded.

[0037] Specifically, most of the existing air conditioning control systems are deployed based on the RS485 bus, and the electronic devices are connected in series with the RS-485 bus and then connected to the server through the gateway. The air conditioning control device 1 can be connected to the external RS-485 bus through the wired communication circuit 610 and the serial bus connector, and communicate with other devices in the existing air conditioning control system through RS-485, so as to be compatible with the existing air conditioning control system. When it is necessary to communicate and send data to an external device through the wired communication circuit 610, the microcontroller module 400 outputs a high level to the gate of the first field effect transistor Q1 through the first resistor R1, and the drain and source of the first field effect transistor Q1 are turned on. At this time, the second end of the communication chip U1 and the third end of the communication chip U1 are turned on with the first working voltage. The second end of the communication chip U1 is set to a high level, and the communication chip U1 is enabled to send. At the same time, the third end of the communication chip U1 is set to a high level, and the communication chip U1 is prohibited from receiving. The communication chip U1 can send data to the outside. Relatively speaking, when it is necessary to receive data from an external device through the wired communication circuit 610, the microcontroller module 400 outputs a low level to the gate of the first field effect transistor Q1 through the first resistor R1, the first field effect transistor Q1 is turned off, the second end of the communication chip U1 and the third end of the communication chip U1 are set to a low level, the communication chip U1 is prohibited from sending, and receiving is enabled at the same time, thereby realizing a half-duplex transceiver function. Exemplarily, the serial bus connector is a MICRO USB, 5PIN connector, the communication chip model is SP3483, and the communication chip can also use other chips with serial communication functions, which are not limited here. The communication chip U1 complies with the specifications of RS-485 and RS-422 serial protocols, and can achieve low-power operation without sacrificing performance, while reducing the electromagnetic interference generated by electronic equipment during its own operation.

[0038] Further, please refer to Figure 4 , the radar module 200 includes: a millimeter wave radar chip U2, a second capacitor C2 and a third capacitor C3; wherein the first end of the millimeter wave radar chip U2 is grounded, the second end of the millimeter wave radar chip U2 is connected to the micro control module 400, and the third end of the millimeter wave radar chip U2 is connected to the power supply voltage VCC_5V; one end of the second capacitor C2 and one end of the third capacitor C3 are connected to the third end of the millimeter wave radar chip U2, and the other end of the second capacitor C2 and the other end of the third capacitor C3 are grounded. The second capacitor C2 and the third capacitor C3 are capacitors with different capacitance values ​​connected in parallel. For example, the second capacitor C2 is 1uF, and the capacitance of the third capacitor C3 is 0.1uF. By connecting a large capacitor and a small capacitor in parallel, high-frequency noise, low-frequency noise and power ripple are filtered out, and power supply filtering, signal decoupling and noise suppression are performed.

[0039] Specifically, the millimeter wave radar chip U2 model is HLK-LD1020, which is a micro / motion sensing chip designed based on the X-band radar chip, with a radar frequency of 5.8GHz. The chip design adopts fixed frequency, directional transmission and receiving antennas, integrates intermediate frequency demodulation, signal amplification and digital processing functions, and has the ability to set delay, adjustable sensing range and light intensity detection. Compared with the defects of using infrared detection and recognition distance and easy false detection, the use of radar has the advantages of not penetrating walls, anti-interference, small size, good clutter and high-order harmonic suppression effect, high stability and consistency. It is set in the case of walls or obstacles reflecting microwaves around, and the sensing distance and sensing angle have gain. In addition, the HLK-LD1020 chip has an internal integrated algorithm, which can directly output the personnel collection information of the detection results, without the need for single-chip microcomputer for data processing and calculation, and supports dynamic / static target distinction, can identify micro-movements (such as breathing, heartbeat), and analyze speed and direction through the Doppler effect, with a low false alarm rate, and can achieve accurate human presence perception.

[0040] Further, the sensor module 300 includes: a temperature and humidity sensor chip U3, a seventh resistor R7, an eighth resistor R8, a fourth capacitor C4 and a fifth capacitor C5; wherein the first end of the temperature and humidity sensor chip U3 is respectively connected to the step-down module 100, one end of the seventh resistor R7, one end of the eighth resistor R8, one end of the fourth capacitor C4 and one end of the fifth capacitor C5; the second end of the temperature and humidity sensor chip U3 is connected to the micro-control module 400, and the other end of the seventh resistor R7 is connected to the second end of the temperature and humidity sensor chip U3; the third end of the temperature and humidity sensor chip U3 is connected to the other end of the eighth resistor R8, and the other end of the eighth resistor R8 and the common end of the third end of the temperature and humidity sensor chip U3 are connected to the micro-control module 400; the other end of the fourth capacitor C4, the other end of the fifth capacitor C5, the fourth end of the temperature and humidity sensor chip U3 and the fifth end of the temperature and humidity sensor chip U3 are grounded.

[0045] The infrared microcontroller chip U6 operates at the first operating voltage provided by the step-down module 100. For example, the model of the infrared microcontroller chip U6 is HLC668, and its built-in infrared code library is used to store the infrared codes of any brand of air conditioner that supports infrared control, so as to control all brands of air conditioners that support infrared control. For example, the guide code, verification method, customer code, data code, etc. of the infrared code, the remote control chip and coding rules used by different air conditioners are different, and the specific coding format will also change accordingly, resulting in many coding forms. The specific coding format of the infrared code can be adaptively adjusted according to the brand and model of the air conditioner used in the space during the specific implementation. Exemplarily, the existing infrared remote control mainly includes two modes: pulse width modulation (PWM) and pulse position modulation (PPM). The infrared microcontroller chip U6 calls the corresponding control signal from the infrared code library.

Specifically, the wireless communication circuit 630 uses a 4G Cat.1 wireless communication chip.

[0047] Specifically, most of the air-conditioning control systems in the prior art are deployed based on the RS485 bus. All electronic components are connected in series through the RS485 bus and then connected to the server 2 through the gateway. A large number of communication cables will also increase the cost of the system. As long as a node has a problem, it is likely to cause the entire bus to be paralyzed, causing system instability. The gateway is passed as a centralized node. If a failure occurs, it may cause the communication of all terminal devices connected to it to be interrupted. At the same time, wifi, BT, 433, and zigbee are short-range communication technologies. If remote control is required, a networked gateway device is required, and a router must be present to connect to the network. Updating the electronic components connected through the gateway in the smart home system to other communication methods requires configuring gateways and relay devices, maintaining multi-protocol compatibility, and consuming a lot of energy for preliminary preparations. Therefore, the wired communication circuit 610 in the present invention can be compatible with the existing RS-485 communication method and network connection through the gateway, and can also support independent terminal networking through the Cat.1 wireless communication chip, so that a single device failure does not affect the overall system stability.

One end of the eleventh capacitor C11 and one end of the fourteenth capacitor are connected to the power input terminal, the cathode of the third Schottky diode D3 and the cathode of the fourth Schottky diode D4 are connected to the common terminal of the nineteenth resistor R19 and the wireless communication circuit 630, and the other end of the eleventh capacitor C11, the other end of the twelfth capacitor C12, the anode of the third Schottky diode D3 and the anode of the fourth Schottky diode D4 are grounded. Exemplarily, the second buck chip U7 uses a 1.5MHz constant frequency, current-type buck conversion chip TMI3408F, the twentieth resistor R20 has a resistance of 56KΩ, and the twenty-first resistor R21 has a resistance of 10K. Then, by calculation, it can be obtained that the second operating voltage value output at the connection end of the buck circuit 620 and the wireless communication circuit 630 is: VOUT=(1+56K / 10K)*0.6=3.96V, and the second operating voltage value is used to provide an operating voltage for the communication chip U1.
