The Implementation Of Power Monitoring Data Manager Based On WCF

SCADA system has entered a rapid development of the period in recent years, and the network monitoring system has become the mainstream of the market. This design taking the electric power real-time monitoring system as the research object, and it taking the SCADA system data manager based on Web as the research subject. Through the analysis of the development status of the current domestic and foreign research, implementing scheme of integrated SCADA system, this thesis ultimately determines the use of three layer structure as the main body of the classic case. It divides the system into three parts:interface layer, data logic layer and communication layer. Thus, the focus of this paper is on the data logic layer. Based on the technology of WCF, WPF, MVVM, Windows service, Data logic layer achieves a complete power monitoring system data manager. Data management realizes the completely separation between the interface layer and the communication layer, and a unified management of all data information monitoring system. This makes the structure of the whole system become much clearer, benefits the system development and subsequent maintenance and enhances the flexibility, stability of the system.This thesis expounds the system location and the functions of Data Manager and realizes the management of monitoring system, real-time data, historical data and configuration information. The Data Manager, as a system service center, will send the collected real-time monitoring data to the data management center for processing through the WCF client. Some part of the real-time data will be pushed into the monitor screen for displaying through the WCF, while the other part will be saved into Mysql database as historical data. The image files generated by Configuration system and the Prerequisites system configuration information will be stored in the Data Manager by service as well.The three aspects of Data Manager will be introduced with details in this paper, each service function, service function of client and service management. WCF is the core technology for manager implementation, which completes all the data transmission among the system modules. It is in pivot position, delivering the live data collected by the communication front-end to the monitor screen, but also sending back the remote control command. Thus, it solves the problem of system coupling too tightly and Implements the data transmission across both machines and network.
