中文摘要:
      二冷水自动化控制系统采用PLC为控制核心,对现场流量、压力、温度等模拟量进行检测,根据工艺配水(气)参量对调节阀进行连续的实时控制调整,通过工控机在线监控系统运行、记录运行数据。系统上线运行稳定,达到了设计目的。
英文摘要:
      In the secondary cooling water automatic control system,the field analog values such as flow rate,pressure and temperature are measured by the PLC which is the kernel controller.Then the regulating value is tuned online continuously in real time according to the requirement of water or air.In addition,the system operation is monitored by the industrial computer online with all the operation data being recorded.The system runs successfully which comes to the anticipant design purpose.
