Detailed ways

The utility model will be further described below in conjunction with specific embodiments, and the schematic embodiments and illustrations of the utility model are used to explain the present invention, but not as a limitation to the utility model

As shown in Figure 1, a smart desk lamp control system based on the Internet of Things, including pyroelectric infrared sensor 1 (1), pyroelectric infrared sensor 2 (2), photoresistor (3), and signal processing circuit (4) , main control system (5), reminder circuit (6), light control circuit (7), Internet of Things (8), user mobile terminal (9), characterized in that: the pyroelectric infrared sensor 1 (1) , pyroelectric infrared sensor 2 (2) and photoresistor (3) together constitute the sensor acquisition module, which are used for

Detect the human body radiation infrared signal and light intensity signal, after processing, it becomes a processable digital signal and sends it to the signal processing circuit (4); the signal processing circuit (4) is used to process the digital signal collected by various sensors, and transmit the processed signal to the main control system (5), and at the same time receive instructions from the main control system (5); the main control system (5) is used to process the signal transmitted by the signal processing circuit (4). After analysis and processing, corresponding instructions are sent to the reminder circuit (6) and the lighting control circuit (7); the Internet of Things (8) provides a network communication platform for the main control system (5) and the user mobile terminal (9) ; The user mobile terminal (9) can remotely control and monitor the desk lamp.

Further, the pyroelectric infrared sensor 1 (1) and the pyroelectric infrared sensor 2 (2) are specially used to receive signals of about 10um generated by the human body, and correspondingly use BISS0001 to process and convert the generated signals as a digital signal that can be processed. First, set the BISS0001 to non-repeatable trigger mode, with a relatively long delay time, in order to obtain a stable output signal, and connect the pin of the receiving photocell to high level, so that BISS0001 thinks it is always in the dark, which is convenient for observation. During operation, when the person is far away, BISS0001 outputs a low level, which meets the requirements, but the signal changes irregularly after the person approaches. Using an oscilloscope to measure each pin of BISS0001, it is found that the main instability of the signal source is due to the sensor. Therefore, in the absence of a better replacement, the current pyroelectric sensor has to be used.

Further, the photosensitive resistor (3) adopts LXD3526.

Further, the signal processing circuit (4) is a signal processing circuit centered on BISS0001, which amplifies the signal twice and filters it to prevent interference from external signals. After the signal passes through BISS0001, it is converted into a digital signal output, which is convenient for processing with a single-chip microcomputer.

Further, the main control system (5) adopts a 32-bit STM32 series single-chip microcomputer.

Further, the reminder circuit (6) uses a 12095 buzzer as a sounding device, and a PNP transistor as a driving device.

Further, when the light control circuit (7) has no external interruption, the 80C51 controls the enable control terminal of the 74LS138 so that the subsequent circuits do not work. When an interrupt occurs, 80C51 starts 74LS138, sends a signal to the lower 4 bits of P0 pin, and controls the light to turn on slowly. When interrupt 1 and interrupt 0 are generated at the same time, 80C51 shields interrupt 1, starts 74LS138 to send data to the lower four bits of P0 pin, and gradually dims the light. The use of 74LS138 to control DC832 here can save the pins of 80C51, which is conducive to expansion, so as to control multiple lamps. Due to the adoption of DC0832, the lamp can be effectively changed into a ladder shape.

Further, the Internet of Things (8) adopts WIFI modules to build an Internet of Things environment, and provides a network environment for each module to communicate with each other.

Further, the user's mobile terminal (9) uses a mobile phone to remotely operate the desk lamp.

The working principle of the utility model: when the ambient light is relatively strong, the resistance of the photoresistor (3) is relatively small, and the signal processing circuit (4) detects a low-level signal, and the pyroelectric infrared sensor 1 (1) and the pyroelectric infrared sensor 1 (1) are prohibited. The infrared sensor 2 (2) works, eliminating the processing process of the main control system (5). When the ambient light is relatively weak, the resistance of the photoresistor (3) becomes larger, and the signal processing circuit (4) receives a high level, thereby starting the pyroelectric infrared sensor 1 (1) and the pyroelectric infrared sensor 2 (2) Work. Pyroelectric infrared sensor 1 (1) detects a relatively long distance. When the human body enters the control range of sensor 1 and the light intensity is weak, the signal detection circuit processes the signal and sends an interrupt to the microcontroller. The main control system ( 5) Start the light control circuit (7) to gradually brighten the light. When the ambient light is weaker than the school and the human body is too close to the table, the pyroelectric infrared sensor 2 (2) detects the signal, and at the same time within the control range of the pyroelectric infrared sensor 1 (1), the signal processing circuit (4) At the same time, a signal is sent to the main control system (5), the main control system (5) processes the signal according to the order of priority, shields the signal of the pyroelectric infrared sensor 1 (1), activates the reminder circuit (6), and sends out an alarm to make people leave , if the desktop is not left within the set time, the light control circuit (7) is started to slowly turn off the light. When the human body leaves the control and detection range of the pyroelectric infrared sensor 2 (2) and is within the control and detection range of the pyroelectric infrared sensor 1 (1), the light gradually brightens again. The user's mobile terminal (9) can remotely control and monitor the desk lamp. Play the role of saving energy, correcting sitting posture, simple and convenient operation.
