Tianjin Electric Information Acquisition System Design And Implementation

With the progress of the China State Grid Corp strong smart grid construction,Tianjin city power company according to the State Grid Corporation of the unifieddeployment, in combination with the actual requirement of the company, carry outthe design and implementation of electric information acquisition system. Systemdesign and implementation of the main purpose is to meet the requirements of theState Grid Corporation of power consumption information collection system "fullcoverage, full acquisition, the prepaid", acquisition and processing of unifypurchasing, supply side, sells the electricity side three links of electric powerinformation, build perfect electricity information collection information dataplatform. Tianjin Electric Power Design of electric information acquisition systemand Realization of software part adopts B/S (Browser/server) architecture, isdeveloped based on J2EE platform. Struts－MVC framework for the development ofapplication system based on WEB, using MVC mode, using AJAX technology in thecomponents of the interface, the B/S interface and C/S interface similar withtraditional rich interface elements and the powerful operation function; the systemsoftware is developed using VC++, in order to improve efficiency; database using amature commercial database Oracle10.0.2.4, development tools using PL/SQL.Tianjin electric power design and implementation of power informationacquisition system mainly use the Tianjin electric power company owned SDH2.5ring network, combined230MHz power system communication network, mobile,Unicom Network by network communication transmission part. Acquisition terminaland metering devices (meters) between acquisition and communication is mainlyused for low voltage power line carrier communication, solve optical fibercommunication,485communication mode.Through the system design and Realization of the intended function of the target,achieved the performance goal design, and solves the high-capacity concurrentconnection processing, data acquisition and load balancing technology, mass datastorage technology, disaster recovery technology and other related technicalproblems. To achieve power users with real-time acquisition and monitoringinformation, serve for marketing management and the business demand. The electric energy data acquisition system to achieve real-time metering device onlinemonitoring and user load, power, voltage and other important information, timely,complete, and accurate for the "SG186" information system to provide the basic data,so as to provide support for the analysis, each link of enterprise managementdecision, improve enterprise intensive, lean and standardized management level.
