[0024] In order to make the person skilled in the art better understand the utility model scheme, the technical scheme in the utility model embodiment will be described clearly and completely below in conjunction with the drawings in the utility model embodiment, and the described embodiment is only a part of the embodiment of the utility model, rather than all the embodiments. Based on the embodiment in the utility model, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the utility model.

[0025] In the technical scheme of the utility model, Figure 1 is the structural diagram provided by the specific structure of the utility model based on the multi-mode communication human body detection sensor system, as shown in Figure 1 The dotted line in the figure is the power supply line, realized as the communication line, and the short straight dotted line is the wireless communication. The utility model comprises:

[0026] The system includes a human presence microwave sensing module 1, an ambient light sensing module 2, a multi-mode communication control module 3, an infrared sensing module 10, a control switch 11, and a power supply module 4. The power supply module 4 is connected to the power supply terminals of the ambient light sensing module 2, the multi-mode communication control module 3, and the infrared sensing module 10, and to the input terminal of the control switch 11. The output terminal of the control switch 11 is connected to the power supply terminal of the human presence microwave sensing module 1, and the control terminal of the control switch 11 is connected to the signal output terminal of the multi-mode communication control module 3. The human presence microwave sensing module 1, the ambient light sensing module 2, and the infrared sensing module 10 are all communicatively connected to the multi-mode communication control module 3.

[0027] The infrared sensing module 10 and the human presence microwave sensing module 1 are both used to sense the human body. The ambient light sensing module 2 is used to detect the ambient light intensity. The multi-mode communication control module 3 is used to communicate with the external device 7 via Bluetooth signal and / or star flash signal. The multi-mode communication control module 3 is used to control the control switch 11 to open according to the detection signal of the infrared sensing module 10, thereby enabling the power supply module to supply power to the human presence microwave sensing module 1. The power supply module 4 is used to supply power to the ambient light sensing module 2, the infrared sensing module 10 and the multi-mode communication control module 3.

[0028] Specifically, in actual operation, the infrared sensing module 10 first detects the human body. After detecting a person, the infrared sensing module 10 sends a human presence signal to the multi-mode communication control module. Upon receiving the signal, the multi-mode communication control module outputs a high level and turns on the control switch to supply power to the human presence microwave sensing module, thus powering it on. The human presence microwave sensing module further detects the presence of a human body, the distance to the human body, and the micro-motion information of the human body. When the human presence microwave sensing module continuously detects no one, it sends a signal to the multi-mode communication control module. The multi-mode communication control module then controls the control switch to turn off, and the human presence microwave sensing module stops working. The infrared sensing module 10 consumes less power, thus achieving the purpose of saving power.

[0029] In one embodiment of this utility model, the human presence microwave sensing module 1 includes a human presence detection radar module, specifically an HLK-LD2402 human presence detection radar module.

The other end of resistor R31 is connected to the output terminal of the power supply module and the source of PMOS transistor Q2. The drain of PMOS transistor Q2 is connected to the power supply terminal of the human body presence microwave sensing module 1. The source of PMOS transistor Q2 is grounded through a capacitor. After receiving the signal from the infrared sensing module 10, the processing chip outputs a high level at the GPIO port to turn on the transistor, thereby making the gate of the PMOS transistor low level, turning on the PMOS transistor, and supplying power to the human body presence microwave sensing module.

[0031] In one embodiment of this utility model, as shown in Figure 5, the infrared sensing module 10 includes an infrared sensing module, specifically an AS312 model.

[0032] In one embodiment of this utility model, specifically as follows: Figure 3 As shown, the ambient light sensing module 2 includes a light sensor module. Specifically, a BH1750FVI-TR module can be used. The ambient light sensing module 2 is used to detect ambient light intensity information, providing decision information for scene control such as switching lights on and off in the smart elderly care system. The SCL and SDA ports of the light sensor module are respectively connected to the I2C port of the multi-mode communication control module 3, and the power supply terminal of the light sensor module is connected to the 3.3V power supply of the power module 3 via a pull-down capacitor.

[0033] In one embodiment of this utility model, specifically as follows: Figure 4As shown, the multi-mode communication control module 3 includes a processing chip and an antenna module. The processing chip is connected to the antenna module, which is used to transmit Bluetooth signals and / or starlight signals. Specifically, the processing chip can be a WS63 chip, and the antenna module can be a KH-IPEX-K501-29. The multi-mode communication control module 3 is used to realize starlight SLE network access, Bluetooth BLE network access, and self-organizing network, and to transmit human presence and ambient light data information. Human presence sensor devices located close to the starlight gateway device or Bluetooth gateway device can be directly connected to the gateway device and access external device 7 through this module. External device 7 can be a smart elderly care system, a smart home control system, a display device, etc. The smart elderly care system and smart home control system are software platforms. After receiving the signal sent by the human detection sensor system, they perform corresponding operations according to their internal logic.

The other port of the charge / discharge management module 42 is connected to the battery 8. When the power supply module uses 220V AC power, the charge / discharge management module 42 cuts off the output of the battery 8 and charges the battery 8. When the 220V AC power is disconnected, the charge / discharge management module 42 discharges the battery 8, at which point the battery 8 begins to supply power to the entire system. The rectifier module 41 includes a TAS10-5-WEDT chip, the charge / discharge management module 42 includes a U14IP5306-CK chip, and the low-dropout linear regulator 43 includes an AMS1117-3.3V chip.

[0036] The multi-mode communication control module 3 establishes a StarSpark wireless connection with the StarSpark gateway. The human presence sensor module and ambient light sensor module 2 send detection information to the multi-mode communication control module 3. The communication module processes the data and converts it into StarSpark SLE wireless data before sending it to the StarSpark gateway. The StarSpark gateway then forwards the data to the external device 7. Alternatively, the multi-mode communication control module 3 can also process the data and convert it into Bluetooth BLE wireless data before sending it to the Bluetooth gateway, which then forwards the data to the external device 7.

[0037] In one embodiment of this invention, the multi-mode communication control module 3 of the multiple human presence sensor systems communicates with each other via Bluetooth signals and / or starlight signals.
