摘　　要：针对目前管道热处理过程中遇到的设备功率小、控温不精确、操作复杂等问题,以智能温控器AI-518为核心设计了一种新型温度控制系统。上位机程序使用图形化开发软件LabVIEW编写,可以修改温控器的各项参数、温度实时显示、数据存储回放,PC机通过RS-485总线与4个温控器相互通信。该系统具有硬件电路简单,控温精确等特点,系统可连续工作200h以上,能完全满足实际应用的要求。For the problems of power small, temperature control inaccuracy and complex operations in the pipeline heat treatment process, this paper designed a new temperature control system based on AI-518. Host computer programs were written in LabVIEW. The system has functions of modifying the parameters of the thermostat, displaying temperature real-time, storing data and displaying back. PC communicates with four thermostats through the RS - 485 bus. The system has the characteristics of simple hardware circuit, and accuracy control of temperature. It can work continuously more than 200 hours and meet the requirement of practical application.
