Design of Sitting Posture Correction System Based on STC89C52 Single-chip Microcomputer
摘要
Abstract
This paper uses STC89C52 single-chip microcomputer as the core device,combined with HC-RS04 ultrasonic sensor,photoresistor,timer,ADC0832 analog-to-digital converter,and LCD1602 LCD screen,to design a sitting posture correction system.Real-time monitoring of the distance between the user and the measured object is carried out through ultrasonic sensors,and the illumination intensity of the environment is monitored in real time through photoresistors.The collected data is processed by the single-chip microcomputer.When either the measured distance or illumination intensity exceeds the normal range,the single-chip microcomputer drives a buzzer alarm to remind the user to pay attention to correction.Meanwhile,the measured data is displayed in real time on the LCD1602 display screen.A detailed study is conducted on the hardware circuit and software design scheme of a sitting posture correction system based on a single-chip microcomputer.Keil software is used for code debugging,and Proteus is used for software simulation.Through functional testing,it has been proven that the designed sitting posture correction system can work normally in various situations.关键词
