本文介绍了一个以微处理机为核心的温度控制系统及其设计过程。内容包括怎样用微处理机来实现给定温度的计算和输入,温度测量和非线性校正,调节以及输出驱动控制。在文章中还提出了几种特别适合于微处理机的控制方法,如阀值可调的多位继电式调节等,既简化了系统结构又提高了性能,解决了某些常规控制方法难以解决的问题。 This article describes a microprocessor-based temperature control system and its design process. Including how to use a microprocessor to calculate and input a given temperature, temperature measurement and nonlinear correction, regulation and output drive control. Several control methods that are particularly suitable for microprocessors are also proposed in the article, such as multilevel relay-type regulation with adjustable threshold, etc., which not only simplifies the system structure but also improves the performance, and solves the problems that some conventional control methods are difficult to handle solved problem.
