水工闸门的自动化管理,是水利现代化的重要组成部分。利用运算放大器实现水工闸门流量的自动控制,电路简单,控制可靠、准确,不需要外加其他工程及结构。并且还可以实行遥控与集中控制、节省大量的人力和水资源。 .一、基本原理利用运算放大器来实现水工闸门定流量控制的基本原理是:将各水位、流量、闸门高度等量值,变换成相应的电压信号,利用运算放大器进行高精度计算、比较,最后驱动执行元件,进行自动控制,见图一。
The automatic management of hydraulic gates is an important part of water conservancy modernization. Utilize operational amplifier to realize the automatic control of hydraulic gate flow, the circuit is simple, the control is reliable and accurate, it does not need to add other engineering and structure. And also can carry out remote control and centralized control, saving a lot of manpower and water resources. First, the basic principles The use of operational amplifiers to achieve hydraulic gate fixed flow control of the basic principle is: the water level, flow, gate height and other values into the corresponding voltage signal, the use of operational amplifiers for high-precision calculation, comparison, Finally, the implementation of drive components, automatic control, see Figure I.
