摘要
随着城市城市化程度深化,地铁作为一种快速、舒适和环保的交通工具在各大城市陆续投入。本课题分析了地铁空调系统的复杂结构,为了实现智能调节各个控制环节,采用群控系统方案,通过采集系统设备信号,由PLC完成冷水机组各个设备的监控功能和连锁保护功能,通过MCGSE组态软件进行人机界面编程及现场运行,可以准确地看到整个冷水机组的运行情况,并反映设备的运行状态。该空调系统降低了地铁工作人员的工作量,实现自动化,提高效率,通过上线运行说明地铁空调系统控制方案合理可行。
As the urbanization of the city deepens, the subway is being invested in major cities as a fast, comfortable and environ‐mentally friendly means of transportation. This topic analyzes the complex structure of the subway air conditioning system. In orderto realize intelligent adjustment of various control links, the group control system scheme is adopted. By collecting the systemequipment signals, the monitoring function and interlock protection function of each device of the chiller are completed by the PLC,and the MCGSE configuration is adopted. The software performs man-machine interface programming and on-site operation, whichcan accurately see the operation of the entire chiller and reflect the operating status of the equipment. The air conditioning systemreduces the workload of the subway staff, realizes automation, improves efficiency, and demonstrates that the subway air condition‐ing system control scheme is reasonable and feasible through on-line operation..
