Technical Research On WEB-Based Enterprise Electrical Network Real-time Monitoring System

With the development of society and national economy ,the electrical energy is acting more and more important role in daily life . The enterprise electrical network real-time monitoring system based on the web is for the purpose of realizing electrical energy visualization.However, the current real-time monitoring system still exists certain deficiencies: l)Traditional refresh technology in the web enviroment has inefficient communication; 2)Relational Database system can not adapt the requirements of data management in real-time systemIn order to solve the deficiencies of the exisiting electrical network real-time monitoring system ,the thesis proposed new enterprise electrical network real-time monitoring system design scheme with the national cleaner production centers project "TITPM-2000 Enterprise electricity power manager" as the application background ,which comprehensive used several key technologies ,including main memory database > real-time data refresh technology and multi-threaded data process technology. The thesis mainly research in the following areas:1)Proposed the system design scheme and particularly analysed the key technology involved in the realization of the system to meet the demand of corporation's electrical network real-time monitoring.2) Put forward some improving ways to solve the potential problems of the《Power load management system data transmission protocol—2004》, such as theunclear hiberarchy,repeated frame counters and data encryption ,and also designed the parse asynchronism of data frames used in the protocol.3) Realized highly effective real-time deposit and withdrawal of the electric power real-time data using Main Memory Database and remote procedure call technology .And also comparative tested the data real-time access performance of the Main Memory Database and Relation Database.4) Realized real-time data updating of the Electrical Network Monitoring System in the WEB environment by using WEB embeded ActiveX object, solving communication inefficiency problem of the traditional refresh technology.5)Designed and implemented the data synchronization multi-threaded process model of Electrical Network Monitoring System on the basis of analysis on multithread classifying and functioning which improved the real-time performance and stability of data processing .
