常规水厂的自动化控制系统主要有三个基本功能,即监测、控制、管理功能。监测功能即生产现场的数据采集和设备运行情况的监视及报警。控制功能,即PLC或计算机根据工艺要求及设备运行参数的变化自动或提示通过操作人员进行控制设备的运行。管理功能,即生产数据处理、事故记录、数据曲线、各信息无法交流,资源不能共享,这样既难提高 Conventional waterworks automation control system has three basic functions, namely, monitoring, control, management functions. Monitoring function is the production site data acquisition and equipment operation monitoring and alarm. Control functions, that is, PLC or computer according to process requirements and changes in equipment operating parameters automatically or prompts through the operator control equipment operation. Management functions, that is, production data processing, accident records, data curves, the various information can not be exchanged, resources can not be shared, so difficult to improve
