摘　　要： 提出了由传感变送器、可编程控制器(PLC)、上位机组成的制冷机组远程监控系统的解决方案,介绍该系统硬件的构建、应用MCGS组态软件开发上位机的组态工程和PLC编程的过程。在上位机和因特网客户端IE浏览器上,运行该系统能实现现场和异地远程监视制冷机组运行状态、数据存储浏览和打印、故障诊断和报警功能、操纵机组和修改被调参数的功能。经过运行检验,该系统能便捷地远程监视制冷机组状态,准确控制机组运行,各功能达到预期要求,提高制冷机组的自动化水平。 A solution of the long- distance monitor and control system for refrigeration unit is brought forward in this paper.This system consists of sensor or transducer, programmable logic controller （PLC） and upper computer.ln the paper, how to build up the hardware of the system and how to develop the configuration work in upper computer by MCGS configuration, the programme of PLC are introduced.When the system runs, the following functions： monitoring the status of refrigeration unit, datum stored and browsed and printed, faults diagnosis and alarm, control the unit and modification the parameter to be adjusted, will be realized by upper computer and the IE browser in the client in Intemet. By operating, it is proved that this system can long - distance monitor the status of refrigeration unit conveniently and control it accurately. The system has achieved the expected demand. It will raise the level of the automation of refrigeration unit.
