1视力保护器的设计摘要:当下，社会经济发展迅猛，计算机网络技术也随之得到一定的进步，在一定程度上改变了当下社会的通讯结构，但是也带来了一些不利影响，最近几年来，青少年近视出现低龄化趋向。青少年视力下降主要受以下几个因素的影响：眼睛距书本过近、长时间用眼、过度使用视屏终端、学习时光线太强或太弱等。此次设计主要针对解决青少年视力下降的问题，设计出一款视力保护器，保护器主体以单片机作为整体的控制核心，对整体硬件电路以及软件电路进行设计操作。其中还包括超声波测距仪模块、光线检测模块、报警提示，模块以及相应的按键模块组成。这一款视力保护器，主要是为了能够加强青少年在学习过程中对于视力的保护。当青少年距离桌面太近或者光线太强时进行提醒。为了对设计进行验证，进行了实物的制作，在最后的调试环节，最后的结果显示，这款视力保护器基本达到了预期的目标。从最后的系统调试结果上来看，整体设计基本符合预期目标，通过超声波测距模块以及光线检测模块的工作，可以在青少年过近或者所处环境太暗的状态下进行报警提示，在实际意义上做到了保护视力的主要目的。关键词：单片机；传感器；定时器；超声波2Design of visual protectorxxx (school of physics and engineering technology, electronic science and technology, level 2015, 2)Abstract:Nowadays, this era is called the information age. In recent years, the rapid development of computer network communication technology has changed the current social communication structure to a certain extent, but it has also brought some adverse effects. In recent years, young people's myopia appears a trend of younger age. The visual acuity decline of adolescents is mainly affected by the following factors: too close to the book, too long use of eyes, excessive use of video terminals, too strong or too weak learning time line, etc.This design mainly aims at solving the problem of young people's vision decline, and designs a vision protector. This protector mainly takes the single chip computer as the control core of the whole system, and designs a...
