摘要
介绍了利用PLC的PID控制功能实现蔬菜大棚温度控制的基本原理,设计了实现其功能的硬件结构并给出了关键设计程序,系统设计结构简单,可靠性高.实验结果表明可以同时对两个蔬菜大棚温度进行控制.
The principles of vegetable greenhouse temperature control system using the PLC PID control functions is introduced. The hardware structure and critical program were described. The system is simple in structure and high in reliability. It is shown by experiment that the temperature of two vegetable greenhouses can be controlled in the same time.
