基于 51 单片机的智能视力保护器摘要：目前，年轻人课业繁重导致的普遍视力低下的现状已经成为国内外共同关注的问题。基于以上原因，本文设计了一款以单片机为主的用来保护视力的仪器。这个仪器用89C51 作系统内核，通过添加相应功能的传感器电路使其能够具备对使用者距离的监测、周围光强的监测与报警功能。定时模块由单片机本身运行程序实现对工作时长的监测。通过 LCD 来对其进行实时显示各项参数，同时能够通过实时快捷的更改各个模块的参数值来满足不同使用者，不同学习环境的视力保护需求。本软件使用的是模块化的设计方式以及采用的是 C 语言进行编程。通过对该产品的开发能够从纠正坐姿上保护年轻人的眼睛，是一种实用有效的方法。关键词：视力保护；STC89C51；传感器 IDesign of Intelligent Vision Protector Based on 51 Single Chip MicrocomputerAbstract: On this day, the school of young people is heavy. And young people have poor eyesight. This situation has become a common concern at home and abroad. In this paper, a method based on 51 single-chip microcomputer is presented. And on that basis, coming up with the idea for a product called intelligent eye protectors and in order to achieve this goal and 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 the following three functions. The first function is to measure the distance from the user. The second function is to measure the intensity of the surrounding light. The third function is to detect the limit beyond the set to achieve alarm. There is a timing module, the timing module is through the SCM itself to run the program, through this way, the product can be working time monitoring. Through the LCD device can realize real-time display of various user settings data. And this device allows users to change the parameters of each mod...
