Daheiting Reservoritr Gate Design And Realization Of Automatic Control System

Gate hoist control system of general adoption of the traditional method of relay - contactorThrough Actions button to complete the task of gate hoist. Since it is a contactless controldevices, intuitive, easy to fault finding and ruled out. Because of the traditional method ofcontrolling simple structure, price, thus meet the needs of a simple control within a certain scope.But with the development of the measurement and control technology, the traditional controlmethod in the reliability, flexibility and defects troubleshooting and other areas has becomeincreasingly prominent, is now gradually be eliminated. With the development of waterconservancy modernization construction and application of gate automatic monitoring system iswidely over the past few years. Fashion now using programmable controller, It has highreliability and configuration of flexible and so on. Operation and Management of Computer usepc, some using industrial controlling computer. In addition, in the course of gate automaticmonitoring system gradually application of advanced technologies, such as distributing controltechnology and distributed Technology of Field Bus Technology of Ethernet technology.This article uses the current epidemic of programmable controller and industrial Ethernettechnology and distributed control technology with the original gate operation used, whileretaining the premise of the original local manual control using hierarchical control structure,comprehensive PLC technology of Industrial Ethernet technology, advanced technology ofconfiguration software technology, local control unit composed of several PLC gates, andthrough optical fiber ring network connected to the PLC formed a ring control network inindustry control computer using configuration software to develop a practical man - machineinterface, good implementation of a gate to the PLC and the controlling and monitoring to ensurethat the entire daheiting reservoir gate Automatic Control System Design of the advanced natureof the specified at the beginning, mature, reliability, availability, real - time, security, open,rational and compatibility of the environment, convenient and economical and reached thedesigned.
