查询词典 time value

This paper introduces how to use PLC realize PID automation control system in constant liquid level system of waterworks though a instance project. It adjusts liquid level by control the valve though PID arithmetic and deals with outside program, makes the liquid level constant at the expectation value. The adjusting time is the same as manual control, but the water quality is better. Its advantages are reaction rapidness, auto-control disengage intervenor, quick protection of fault, more safety and stabilization.

本文以一工程实例介绍了如何用PLC在水厂的滤池实现PID恒水位控制，它通过PID算法和外围的程序处理，通过控制阀门开度来调节水位，使水位基本恒定在期望值，并且阀门调节次数基本与手动调节一样，但水质却明显好很多，更重要的是对现场适应能力强，反应快，而且完全脱离人为干预进行全自动控制，对故障也有快速保护，更具安全稳定性。
