摘要
介绍了供橡塑机械使用的网,基于高性能的16位单片机80C196KC,采用热电隅检测温度的多点温度控制器,并有软件的冷端温度补偿。通过PID控制算法以PWM方式控制加热器以获得高精度温度控制,同时控制器还有全双工RS-485通信接口实现联网通信,以便于对参数进行设置及获得更高点数的控制。
An intelligent multiple channels temperature controller is presented in this papar. This controller is based on 16bit MCU 80C196KC, thermocouples are used to detect temperature. The environment temperature is detected by AD590 to compensate through software. PID arithmetic is used to compute control signal. The heating coil is controlled by PWM signal according to the PID results. It can communicate with upper controller via RS-485 serial communication, so the parameters can be set on line and more channels can be controlled by form a network.
