摘要
根据A/D转换原理 ,用AT89C2 0 51内置的模拟比较器替代以往的ADC芯片来构成采样输入电路 ,用较少的芯片实现了一个温控系统。同时 ,本文还详细介绍了本温控系统的组成、原理及控制算法。
The circuit of sampling input is made up of inner comparer of AT89C2051 instead of traditional ADC chip according to the theory of A/D conversion, and the system of temperature controlling can be constructed by less chips. And the components, principle and controlling arithmetic of this system are introduced in detail.
