Design And Implementation Of Ying Huang Ji Qing's Station Remote Monitoring System

Wang Nou Pump Station as a central station of Ying Huang Ji Qing is an important engineering facilities, in flood control, drainage and drought mitigation, inter-basin water transfer project is playing an important role. Traditional pump station work is mainly to take measures to establish the WaterLevell gauge in the river bank to arrange for regular collection of data; and the need to arrange their staff on duty 24 hours channel embankments to prevent all kinds of vandalism; hydrological data entirely artificial and telephone Chuan reported; when the event of an accident in urgent need of repairs, or need to change the WaterLevell, the pumping station staff have to frequently travel to and from the scene in the control room and work between, not only a waste of manpower, material and financial resources, but not real-time observation, control and maintenance.With the rapid development of water resources, water conservancy project of automation has improved continuously, set to monitor, measure, control, protection, management in one of the pumping station computer monitoring system has been widely applied. Pumping Station to meet the real-time monitoring of various operating parameters need to run for the pumping station to achieve the "no man's duty, duty and fewer people" have created favorable conditions, to a large extent reduce the operation and maintenance of the labor intensity, and that the monitoring system easy to operate, reliability, but also through the network and optimize the unit's own scheduling, the realization of the economic operation pumping station.In order to adapt to this new demand, the subject of design and development of the Ying Huang Ji Qing pumping station remote monitoring system, run through the entire design, testing, analysis, proof of real-time and reliable.First, the introduction of the Wang Nou pumping station remote monitoring system status and direction of development at home and abroad, and then the system needs analysis, to determine the Wang Nou pumping station remote monitoring system design goals and functional requirements will be pumping station remote monitoring system is divided into data acquisition subsystem , data transmission subsystem, information processing and control subsystem of three subsystems, in which the functions of data acquisition subsystem is: through the sensors and control systems are measurement data, including the switch, analog, temperature, WaterLevell and other operating parameters, and From the information processing and control subsystem; the implementation of information processing and control subsystem orders, according to information processing and control subsystem of the operating parameters of downlink control field devices. Information processing and control subsystem functions are: on-site equipment for the operation of real-time monitoring, including WaterLevells, pressure, temperature, water pumps running, etc.; receive from the data acquisition subsystem returns all site survey data, as collated and kept into the SQL database; receive transmission from the data acquisition subsystem of the fault information; at the scene of the operation of the data to do a valid statistical analysis, and mapping trends, easily accessible; operational status of equipment control and operation. Data transmission subsystem's function is: responsible for data acquisition subsystem and the information processing and control data transfer between subsystems; with superior interface communications dispatch center, the site of the data timely and accurate dispatch center sent to higher authorities, and accept the higher level control center issued the scheduling order, the realization of long-distance transmission of data information. Followed by a detailed introduction of the Pumping Station Monitoring System database design, data acquisition sub-system design, data transmission sub-system design, information processing and control subsystem design, and finally introduce its realization method.According to the actual situation of demand, the system developed under Windows, control interface using Visual Basic 6.0 language and Microsoft SQL Server2000 database management system design and development, realize all the features of the system. Test showed that the integrity of the system functions, convenient operation, visual effects, and to meet the operator of a remote pump station monitoring capabilities.
