摘要：本文是以MCS-51蒸纱锅
单片机系统为基础的，通过热电阻的阻值随温度的变化而得到的模拟信号进行采集，连接多路模拟开关实现多路模拟信号的采集，并通过A/D转换器对模拟信号进行数模转换，把转换得到的数字信号按照顺序分别送入单片机或把指定的那路信号送入单片机，通过单片机进行控制操作。本文通过单片机报警系统来实现热电阻传感器测量的温度范围-50-100摄氏度，若超出这个温度范围则报警。以单片机为核心完成温度检测、数据处理.过流保护电路显示及上下限报警功能。本系统设计简单，性能稳定，能够通过单片机灵活编程进行各种功能的设定和修改。 关键词：A/D转换器;热电阻;防眩通路灯单片机

萝卜切条机Abstract: It is based on MCS-51 one-chip computer system for this text to design, is it gather to go on through thermal resistance changer to analog signal that thermal resistance receive with change of temperature, join many way analog switch realize many way collection of analog signal , is it count through A/D converter to analog signal mould change to go on, Send digital signal received to change according to order into one-chip computer
or designated those distance signal send into the one-chip computer separately, carry on control operation through one-chip computer. This text realizes 200~700 degrees Centigrade of temperature ranges that the thermal resistance sensor measure at the same time through the warning system of the one-chip computer, if beyond the scope of this temperature to report to the police. Regard one-chip computer as the core and finish temperature and patrol examining , data processing. Show and the warning function of upper and lower limits.
Key words: A/D converter; thermal resistance changer; an one-chip computer
