Research And Realization Of Remote Monitoring System Of Pump Station Group In Irrigation District

Usually an irrigation area has many small pumping stations and many small sluice gate station,these are geographically dispersed,remote operation and management,the usually need someone on duty boot,manual operation and record data,without automation and information,low operation efficiency,easy to achieve unified management of the entire watershed.In order to solve the above problems,efficient and reasonable scheduling allocation of irrigation area water resources,the use of programmable logic controller(PLC),to carry out research on small irrigation information system,a variety of sensor configuration technology,GPRS technology and computer technology,realize the monitoring and management of pumping station,sluice operation in local and remote control room.This paper first introduces the research status and development trend of domestic and international water conservancy project information system,according to the specific needs of pumping station,sluice Shatou information transformation of the specific design of the remote monitoring system of irrigation area.Due to the wide range of distribution in each pumping station,pumping station control using PLC,touch screen,etc.all kinds of sensor devices and control unit to LCU control cabinet,control cabinet by using LCU and 3G/4G wireless communication patterns respectively through VPN gateway and GSM wireless communication module for communicating with the monitoring center,to achieve most of the transmission station the number of HD camera images,remote control,and Xijiang ecological park,a village of pipe pump station with the running state and remote access PC mobile phone in LCU units,and the implementation of pumping station,sluice unit message start stop control function.The comprehensive database server is set up in the remote pumping station control management center,and the data transferred from each pumping station is stored in the database.Using Kingview configuration,the data into the SQL Server widely used in the market,convenient for all levels of management units for data query,processing.At the same time,the Web server of the pumping station information management system based on B/S structure is set up in the remote control center,and the field and remote control mode switching can be realized.The remote information management center by ASP.NET,ADO.NET,and SQL database connections,real-time display of pumping station,the operation status of the unit gate,water level and flow of information,the user login system through the LAN can be real-time understanding of the relevant information,the user administrator for remote pumping station,sluice on-off control,centralized monitoring and controlling the dispersion of pumping station the function of the reasonable allocation and implementation of irrigation area water resources.
