| With the rapid development of our social economy,power users‘demand for the power supply quality and service quality increase daily.The power purchasing and selling system is used to implement the abnormal electricity automatic data collection,measure power quality monitoring,analysis and management function.Since the new China was founded,the end of the electricity grid placement link has always been in a labor-intensive traditional marketing model,relying on artificial field meter,rushing fee charging,which is low labor efficiency,and the service quality is difficult to guarantee In recent years,the development of wireless,broadband communication sand network application technology,laid a foundation to achieve data remote transmission quickly,to share cross-industry data,to optimize the allocation of social resources and to build a modern business platform.In order to do better in the electric power security work of regional economic development,power supply company need to build a set of power purchasing and selling system which meets the national and industry standards,suit for district power characteristics,have full coverage,full collection,full fee charged with",the system can make limited electric power resources produce the greatest economic benefits and social benefits,work as the escort for the national economy development to prefecture.This article primarily introduced the idea design,function design and implementation scheme of power purchasing and selling system,and each function module of the system and the realization of hardware and software process in detail.According to the characteristics of the system,by the system structure,system analysis and design,dates design and data exchange with other systems,were to establish a safe perfect application,flexible expansion,maintain an convenience system.This article main content is as follows:(1)Through the research,we understand the detailed demand of prefecture power purchasing and selling system,and concludes the functional requirements of the system through the analysis of the UML tools;(2)Completed the design scheme of prefecture power purchasing and selling system,shows the system main design view,CDM,PDM,data flow chart,etc,completed the detailed design of three functional modules of the system,including electricity collection management module,electricity pre-selling management module and system management module;designed date of case management system in detail using Power Designer tool.(3)We used the Microsoft.net platform to realize the system,used the c# language to finish and test electricity collection management module,electricity pre-selling management module and system management module of the prefecture power purchasing and selling system.At present,prefecture power purchasing and selling system has been built and put into use.By real-time collection of the residents watt-hour meter data,the system effectively improves the efficiency of meter reading,eases the meter reading meter reading personnel strength,reduces the metering error caused by human factors,improves the service quality of power supply enterprise,establishes a good image of the electric power enterprise,also can reduce the electric power enterprise workers and increase efficiency,reduce the electricity cost,help to strengthen the management of electricity. |
