摘　　要：热风机是以燃油或燃气的燃烧作为热量来源,调节空气的热交换量来达到控制温度的目的。本文提出了一种基于Fatek PLC的热风机控制系统设计方案,主要介绍其温度控制系统部分和上位机软件部分,可实时控制热风机,并反应温度曲线,具有很好的可视化效果。The air heater uses the energy which is produced by combustion of oil or gas to adjust the heat exchange capacity to control the air temperature. This paper introduces the design of an air heater control system based on Fatek PLC. We mainly introducs the temperature control system and PC software. The PC software can control air heater and display the temperature curve in time. It has achieved good visual effect.

关 键 词：PLC 热风机 温度PID 实时曲线
