Embodiment of the present utility model is referring to Fig. 1, and this figure is the structure and schematic diagram of embodiment.

The system of the utility model is established on the basis of the existing solar human body induction lamp, wherein the solar human body induction lamp is the host body of the utility model.

In addition to the PIR human body induction module and the MCU central control circuit, the host also includes solar cells, charging circuits, voltage regulator circuits, low voltage detection circuits, photometric detection circuits, lighting LED circuits and wireless transmitter modules. Wherein the solar battery is connected to the charging circuit, and the received solar energy is converted into electric energy and stored in the storage battery of the charging circuit. The charging circuit is the power supply of the host and supplies power to the host as a whole. The control body of the host is the MCU central control circuit, and the MCU is connected to the charging circuit through a 3.3V voltage stabilizing circuit and a low voltage detection circuit. A photometric detection circuit is connected in series between the MCU and the solar cell. The lighting LED module is connected to the voltage stabilizing circuit and the MCU, which is controlled by the MCU and powered by the charging circuit for lighting. The wireless transmitter module is connected to the MCU, and also connected to a host function conversion key S3. In the initial state, the host is a solar human body induction lamp, and the LED lights up under the control of human body induction. Press the host function switching key S3 to indicate that the LED is illuminated for a long time. At this time, the LED is not controlled by human body induction, but provides lighting for a long time. At this time, the host is a solar light; press the host function switching key S3 again, and then enter the initial state, the LED lights up under the control of human body induction, and the host is Taineng human body induction light at this time. Press and hold the host function switch button for more than 2 seconds. At this time, it enters the code learning state, which means that the host sends the identification code to the prompter. After sending, the host LED will flash once. At this time, the host has an alarm function and automatically exits. to the initial state. Steady lighting means that it is not controlled by the human body sensor module and provides lighting for a long time.

Learning code: mainly through the host RF to send out the identification code. After receiving the identification code, the prompter saves it in the memory as the identification code for transmission and reception. Every time the host transmits a signal to the prompter through RF, the prompter receives it. After the signal, first compare the identification codes. If it can match any set of identification codes stored in the memory, the prompter will process the signal and take relevant actions. Otherwise, it will be regarded as a useless signal and will not take any action. The main purpose of using the learning code is to enable a prompter to be paired with any host through simple learning code pairing to receive and process the human body induction information emitted by the host that has been paired with it, without being affected by hosts other than the pairing.

The prompter includes a wireless receiving circuit (that is, a wireless receiving module), an MCU control circuit (that is, a controller) and an alarm device. Both the alarm device and the wireless receiving circuit are connected with the MCU control circuit, the wireless receiving circuit receives the human body induction information 3 emitted by the wireless transmitting circuit, and the MCU control circuit controls the alarm device to alarm. The alarm device has a buzzer (or horn) 1 and an LED light 2 all connected to the MCU control circuit. There is also a sound selection switch S1 in series in the circuit of the buzzer 1 . The prompter also includes a code learning pairing function key S2, which is connected with the MCU controller.

Each module of the above embodiment is described as follows.

For the function description of the prompter, see Figure 2 for its circuit diagram. This reminder is mainly placed indoors to remind whether someone enters the PIR detection area of the solar light. When the PIR detects that a person enters the detection area, a signal is transmitted by triggering the wireless transmitting module in the lamp body. After the antenna of the receiving module of the reminder receives the signal, the buzzer SP1 will make a prompt sound, and at the same time LED light D1 flickers (like automatically stopping after 30 seconds), to remind the indoor personnel that someone outside enters. It can play the functions of prompting and anti-theft. The prompt sound can be controlled by selecting ON/OFF through the sound selection switch S1.

This prompter adopts learning code and can be used with multiple hosts. Code learning pairing function key S2 is a button for learning code or clearing code. Press the switch once to enter the code learning state. Within 5 seconds, if a code learning signal is received from the host of the solar light, the prompter will automatically save this code as the identification code of the prompter and the solar light. If no code learning signal is received, the prompter will automatically exit the code learning state. If you want to clear the saved identification code, just press and hold the learning code pairing function key S2 for about 2 seconds. The prompter will automatically clear all stored IDs.

The working principle of the prompter is explained by referring to the embodiment of the prompter in Fig. 2: the prompter adopts the intelligent RF data transceiver chip CC1100 launched by CHIPCON. It is used to receive and process the data signal sent by the transmitting module on the solar lamp body. After the signal is received by the antenna and processed by CC1100, it is output to the central processing chip (controller) MSP4302121 of the prompter. If it is an alarm signal, it is processed and controlled by the central processing chip, and the fifth pin outputs a flashing signal to make the LED light D1 flashing; and its fourth pin outputs an alarm sound signal, which drives the buzzer through the triode Q1 to send out an alarm sound. It will stop automatically after about 30 seconds (the alarm sound and automatic stop time can be adjusted according to the needs of the software).

The sound selection switch S1 in FIG. 2 is a toggle switch, which is used to select whether an alarm sound is required. Code learning pairing function key S2 is a tact switch, press the tact switch once to enter the code learning state, and the prompt LED is always on. If there is a code learning signal sent from the host of the solar light, the prompter will automatically save this code as the identification code of the prompter and the solar light. At the same time, the prompt LED flashes once, indicating that the code learning is successful, and it will automatically exit the code learning state. If the code learning signal is not received within 5 seconds, the prompter will automatically exit the code learning state. If you want to clear the saved identification code, just press and hold the learning code pairing function key S2 for about 2 seconds. The prompter will automatically clear all saved identification codes, and at the same time, the prompt LED will flash three times, indicating that the clearing is successful. Every time when the prompter receives the alarm signal, the MCU of the prompter will compare whether the identification code is any one of the saved groups. If yes, it will output the sound and LED flashing and signal, otherwise no action will be taken.

This part is composed of PIR human body induction circuit, emission and MCU central control circuit, LED lighting control circuit (lighting LED module), solar charging circuit, low voltage detection circuit, voltage stabilizing circuit and light control circuit, etc. It uses solar panels to convert light energy into electrical energy, and recharges the rechargeable battery without replacing the battery. When the surrounding environment is bright, it will automatically turn off the lighting function and charge the battery. When the brightness of the surrounding environment is weak, it will automatically turn on and provide lighting under the control of the PIR human body sensor, and automatically turn off after a specific time delay, and at the same time send a signal so that the prompter can receive it and remind the indoor personnel to play a role. Prompt, anti-theft function. You can also choose the constant light function, which is not controlled by PIR at all, which is convenient for providing long-term lighting.

PIR human body sensing module, see Figure 3. This circuit is mainly used to identify whether someone passes by the solar lamp, and when someone passes by and enters the detection area, a control signal will be output. As a control signal for lighting up and sending out alarm signals. It uses a pyroelectric infrared sensor. It works as follows. The human body has a constant body temperature, generally at 37 degrees, so it emits infrared rays with a specific wavelength of about 10 UM. The pyroelectric infrared sensor works by detecting the infrared rays emitted by the human body around 10 UM. The infrared rays emitted by the human body around 10 UM are enhanced by the Fischer filter and then gathered on the infrared sensing source. Infrared induction sources usually use pyroelectric components, which will lose their charge balance when they receive changes in the infrared radiation temperature of the human body, and release charges to the outside, through operational amplifiers, voltage comparators, state controllers, and delay timers And the digital-analog hybrid dedicated CDT5456 integrated circuit processing composed of blocking time timer and so on. The CDT5456 integrated circuit chip outputs the delay control signal to the fourth pin of MCUMSP430F20X1 of the lamp body receiving module. The first delay switch S4 and the second delay switch S5 in the module respectively select the output delay time, the first delay switch S4 is ON, the output delay is 10 seconds, the second delay switch S5 is ON, At this time, the output delay is 20 seconds. The output delay time can be adjusted by changing the capacitance values of the eighth capacitor C8 and the eleventh capacitor C11. The greater the resistance value of the fifth resistor R5 in the module, the farther the PIR sensor can detect.

Refer to Figure 4 for the functional description of the launch and MCU central control circuit. This unit circuit is mainly controlled by the control signal output by the PIR sensor module, which emits an alarm signal and controls whether the LED is lit. The working principle is described below. This single original circuit adopts intelligent RF data transmitting chip CC1150 and low power consumption MCUMSP430F20X1. When the PIR sensor module outputs a high level to the fourth pin of MSP430F20X1, it is processed by MSP430F20X1 at this time, and the twelfth pin of MSP430F20X1 outputs a high level, so that the lighting LED is lit, and after a specific time delay Automatically turn off the LED, and at the same time MSP430F20X1 outputs a prompt signal, which is processed by the CC1150 chip data transmitting chip. transmitted through the antenna. The third pin of MSP430F20X1 is low voltage detection, when the voltage of this pin is lower than 1/2VCC, all functions will be automatically turned off. The second pin of MSP430F20X1 is light control, when the voltage of this pin is higher than 1/2VCC, all functions will be automatically turned off.

LED lighting control unit circuit, see Figure 5. This unit circuit is a lighting circuit. When the output of the twelfth pin of MSP430F20X1 is high level, the transistor Q2 is turned on, so that the LED lamps D2-D7 are lit to provide illumination.

Refer to Figure 6 for solar charging, low voltage detection, and light control unit circuits. During the day, solar panels convert light energy into electricity to charge rechargeable batteries. When the light is dark and the second pin of MSP430F20X1 detects that the voltage divided by the ninth resistor R9 and the thirteenth resistor R13 is lower than 1/2VCC, the PIR sensing function is activated at this time and enters the detection standby mode. When the third pin of MSP430F20X1 detects that the voltage divided by R10 and R11 is lower than 1/2VCC, all functions are automatically turned off.

See Figure 7 for the voltage regulator circuit of the power supply. This unit circuit uses HT7133 3.3V three-terminal regulator core to provide a stable 3.3V working voltage for all unit circuits.
