| 针对目前转轮除湿研究中，温湿度测量以干球温度、湿球温度测量为主，存在测量过程复杂，误差大等缺点，提出了基于WinCC和S7 -200PLC的转轮除湿多点温湿度监测系统。以转轮除湿机中处理风和再生风进出口及环境的温湿度作为研究对象，研华工控机IPC-610H作为上位机，西门子S7 -200作为下位机并作为控制器控制执行机构进行数据采集。通过EM231扩展模块进行数据交换，以SIMATIC WinCC组态软件做上位机监控画面，实现对转轮除湿机多个位置的温湿度监测。现场应用结果表明该系统便于管理，控制灵活，稳定性强。系统能简化测量过程，提高测量精度。 |

| In the current study of rotary dehumidification, temperature and humidity is measured by dry bulb temperature and wet bulb temperature measurement, where lies some shortcomings such as complex measurement process,measurement errors and etc. Multi-point temperature and humidity monitoring system in rotary dehumidification based on WinCC and S7-200 PLC was proposed in this paper. Temperature and humidity of air and renewal air of inlet and outlet sides of rotary wheel dehumidifier were taken as object of study. IPC-610H of Advantech was used as upper machine and S7-200PLC of Siemens as lower machine. The lower was used to control the actuator and acquire date which was transferred to the upper by EM231 module. The upper was a control system that could be used to monitor multi-point temperature and humidity by WinCC configuration software. The application and practice show that the monitoring system is easy to manage, flexible and stability. The system can simplify the measurement process, improve the measurement accuracy. |
