As shown in fig. 3, the single chip microcomputer 12 is an STC89C52 single chip microcomputer, and as a controller with low power consumption and high performance, STC89C52 has 8k bytes and can program a Flash read-only program memory. In addition, the storage space is large, and the serial port can be directly used for downloading, so that an efficient and simple solution is provided for the system, and the operation of the system is guaranteed. And a peripheral crystal oscillator circuit, a power supply circuit and a reset circuit are combined to form a minimum system of the single chip microcomputer.

The lighting circuit utilizes the S8550 triode as a drive to be connected with the input port of the singlechip, and the conduction condition of the triode is low level, so that the triode can be conducted as long as the output of the singlechip is low level, and the LED can be lightened naturally.

The human body induction module 11 is a human body induction module of HC-SR51 type, and has the advantages of excellent reliability and sensitivity and low voltage.

The distance detection module 10 is of a type E18-D80NK, the distance detection module 10 is a photoelectric sensor integrating transmission and reception, and the detection distance can be adjusted according to different requirements. When the human body enters the set distance range of the infrared probe, the alarm can automatically start to remind, and the sitting posture is corrected to prevent myopia.

The type of the temperature and humidity sensor 17 is SHT 75.

The buzzer 12 needs a large direct current voltage to supply power for working, but the current output by the IO port of the single chip microcomputer is too small, and in order to ensure normal working and operation of the alarm, the buzzer can make a sound and needs to utilize the function of a triode switching tube. Here we use a PNP transistor S8550, which sounds when the output is low.

The key module 8 comprises a mode switching key 7 and a brightness increasing and decreasing key 9, and because the number of keys is small, the key module selects a circuit mode of an independent keyboard for operation in order to make the design simple and convenient to operate.

The illumination intensity acquisition module 14 includes a photoresistor and an a/D conversion chip. The photoresistor is very sensitive to light, the resistance value of the photoresistor changes along with the change of the intensity of the external light, and when the light becomes strong, the resistance value is reduced; when the light becomes weak, the resistance becomes large. And then the electricity at the two ends of the photoresistor changes along with the change of the illumination intensity. The A/D conversion chip adopts ADC0832 with 8-bit resolution, converts the acquired analog voltage signal into a digital signal and sends the digital signal to the singlechip 12 for processing, thereby realizing the control of the brightness change of the desk lamp.

The specific working principle is as follows:

the STC89C52 single chip microcomputer is mainly used as the single chip microcomputer 12 of the device, the reset circuit and the crystal oscillator circuit form a minimum system, and the operation effect of the desk lamp is realized under the combined action of the key module 8, the illumination intensity acquisition module 14, the human body induction module 11, the distance detection module 10, the illuminating lamp 3, the buzzer 19, the Bluetooth module 15, the sound box 2 and other modules.
