基于单片机的坐姿报警系统的设计(附电路原理图,程序清单,元器件清单)(论文11000字,程序清单,元器件清单)
摘要：在社会经济和各行业技术均得以快速发展的情况下，人类的生产和生活方式也有了不小的改观。社会的不断发展带来了很多新的产物，这些新的产物本身的作用和功能是好的，但是当人们长时间使用的时候就难免会出现一些不利的因素，目前大多数人因工作学习的需要，长时间盯着手机、电视、电脑屏幕，如果没有一个好的光线环境和坐姿习惯就会出现近视。本次的设计就是一个关于多功能坐姿报警仪器的单片机设计，整个设计就运用到了单片机89C52相关的软件和硬件部分，其中还涉及到以下几个功能模块：（1）温度补偿模块；（2）声光报警模块；（3）超声波测距模块；（4）LCD显示模块；（5）声光报警模块，可对人体的坐姿进行客观检测，以判断其是否标准。若是测量值在安全值范围以外，那么，声光报警将会启动。与此同时，它还会通过无线传输模块向指定单位发送报警通知。

Sitting position alarm system based on single chip microcomputer
Abstract：With the rapid development of social economy and technology in various industries, the production and life style of human beings have changed a lot. The continuous development of society has brought about many new products, the role and function of the new new product itself is good, but when people use for a long time is hard to avoid can appear some negative factors, currently studying the needs of most people work for a long time staring at the mobile phone, TV, computer screen, if you don't have a good light environment and posture habits will appear myopia. This design is about a multi-function sitting position alarm instrument single-chip design, the whole design is used in the single-chip 89C52 related software and hardware parts, which also involves the following functional modules :(1) temperature compensation module; (2) acoustooptic alarm module; (3) ultrasonic ranging module; (4) LCD display module; (5) sound-light alarm module can objectively detect the sitting posture of human body to judge whether it is standard or not. If the measured value is outside the safe range, then the sound-light alarm will be activated. At the same time, it also sends an alarm notification to the specified user through the wireless transmission module.
