三、水厂自控系统的功能1.中央控制室硬件配置和功能(1)硬件配置三台电脑,一台用于控制,一台用于监视报警和报表输出,另一台用于驱动模拟屏.若与公司调度系统联接,驱动模拟屏的电脑可兼处理与调度系统的通信和监视管网的供水情况.也可使同一台电脑既具有控制功能,又具有监视报警和报表输出功能,把用于控制和监视的两台电脑配置成功能完全一样.这样,两台电脑可互为备用,这就大大地提高了系统的可靠性,但控制的响应速度不及前者快.
III. Functions of the Waterworks Automatic Control System 1. Central Control Room Hardware Configuration and Functions (1) Hardware Configuration Three computers, one for control, one for monitoring alarms and report output, and the other for driving the analog screen If connected with the company’s dispatching system, the computer that drives the analog screen can handle the communication with the dispatching system and monitor the water supply of the pipe network. It can also enable the same computer to have both control functions and monitoring alarms and report output functions. The two computers used for control and monitoring are configured to function exactly the same. In this way, the two computers can be used as backups. This greatly improves the reliability of the system, but the control response speed is not as fast as the former.
