发动机电控系统水温调理电路仿真设计

摘要

One kind of water temperature conditioning circuit model is introduced by using Proteus combined with Keil as design software. The 80 C51 single chip is used as a control nucleus. The Pt100 sensor is used to measure the temperature of the water of diesel engine, and the output electric singal is conditioned and converted. Finally, the displaying and indicator lights are shown when the temperature exceeds the limit value.%介绍一种应用Proteus单片机仿真软件结合Keil代码编译软件实现的发动机电控系统水温调理电路模型设计.该设计以80C51单片机为控制核心,通过铂电阻Pt100温度传感器检测被测发动机冷却水温度,输出电信号经过调理放大及A/D转换进入单片机,实现最终数码显示及指示灯超限报警.
