基于PID的单片机温度控制系统摘要：本设计主要任务是完成电阻炉的温度测控，利用C8051单片机套件模块作为核心器件配以适当的外围电路实现温度调节，实施温度监控。这个系统分为硬件和软件两大部分，其中硬件部分包括温度检测.转换部分的K型镍铬-镍铝热电偶，变送器，控制部分的C8051F060单片机套件模块，以及执行部分的固态继电器等。软件部分主要包括主程序，T0中断程序以及嵌套在T0中断程序中的几个程序等几个部分。该系统主要采用软件来实现对温度的控制。本设计中，采用PID控制来实现对温度的控制。当温度发生变化进而产生一个偏差量时，通过PID算法从单片机口上输出一个脉冲，偏差量的大小不同其输出脉冲的宽度也相应的改变，从而改变了固态继电器的接通时间，最终改变加热丝功率，以达到调节温度的目的。 我们将热电偶、输入输出通道、单片机模块等环节构成一个温度单回路数字闭环控制系统。利用单片机来对温度进行控制，不仅具有控制方便、组态简单和灵活性大等优点，而且可以大幅度提高被控温度的技术指标，从而能够大大提高产品的质量和数量。Design Of SCM’s Temperature Control System Based On PID Abstract：Design of the main tasks is to complete the resistance furnace temperature monitoring, Boards using C8051 MCU module as a core device temperature regulation, the implementation of temperature control. The system is divided into two parts-hardware and software. Which also includes hardware detection of nickel chromium / nickel and aluminum two thermocouple transmitter, control part C8051F060 Boards module, operative and other solid-state relay. Some major software also includes main program and procedures T0 interrupted several parts. This system mainly use software control temperature. I use PID control the temperature in this design. When the temperature changes result in a deviation of, through the PID algorithm to change its output pulse width, thus changing the solid state relays on-time and eventually change the heating wire power, to achieve the purpose of regulating temperature. We will thermocouple, the input and output channels; the MCU module links constitute a single loop digital temperature closed-loop control system. SCM right to control the temperature, control is not only convenient, simple configuration flexibility and the advantages of large, but can substantially increase the temperature was charged with the technical indicators, which can greatly enhance the quality and quantity.
