基于51单片机的智能视力保护器

Design of Intelligent Vision Protector Based on 51 Single ChipMicrocomputerAbstract:On this day,the school of young people is heavy.And young people have pooreyesight.This situation has become a common concern at home and abroad.In this paper,amethod based on 51 single-chip microcomputer is presented.And on that basis,coming upwith the idea for a product called intelligent eye protectors and in order to achieve this goaland paid the actual action.This product is based on 89c51 as the core structure of the system.This product can add some function to the sensor module.Then the product can perform thefollowing three functions.The first function is to measure the distance from the user.Thesecond function is to measure the intensity of the surrounding light.The third function is todetect the limit beyond the set to achieve alarm.There is a timing module,the timingmodule is through the SCM itself to run the program,through this way,the product can beworking time monitoring.Through the LCD device can realize real-time display of varioususer settings data.And this device allows users to change the parameters of each moduleanytime and anywhere.This function can meet the needs of different users in differentenvironments for the protection of vision.This product is programmed using a modulardesign approach.This product is programmed in the use of modular design and in the use ofprogramming language is C design language.Through the development of this product,itcan protect the eyes of young people from correcting the sitting posture,which is a practicaland effective method.Keywords:Vision protection ;STC89C51;Ultrasonic;
