Under the background of one-account-one-meter electrical supporting policy in China,this paper makes extensive and profound research and discussion about the theory and the present application card recharging system at home and abroad. And then, further more analysis the weaknesses of the current card recharging system in the electricity industry. Finally, combined with the system functions and the business processes of the existed electricity marketing system in XXX City Power Authority, it designed the system and put it to practice.The system uses J2EE technology ,with MyEclipse 8.5 as Integrated Development Environment ,Tomcat 5.0 as Application Platform , PowerDesigner as object-oriented modeling tool,ERWin7.3 for modeling tool to database, Sybase 12.5 as the database, combination of IVR(Interactive voice response ) plates and voice processing software to achieve.The system mainly includes ten software modules: Prepaid card released management, inventory management, sales management, Account management, recharge management, operation management, security management, Marketing account interfaces, IVR(Interactive voice response ) recharge processes and IVR(Interactive voice response ) interface.This system is about to improve and complete two weak links that exists in other similar system。One is security. Security is one of key factors of determine whether the success of the system. This paper made a comprehensive and detailed analysis for safety of the prepaid card payment system, and gives practical solutions. The second is the optimization of voice processing. Prepaid card processing efficiency not only affects system performance, also directly affect the user’s attitude on the power company’s services. Therefore, the voice processing are optimized and made relevant technical processing in this paper.Finally, through tests, test run and actual operations to prove that the system has security and easy scalability, portability, compatibility, ease, in line with user needs, to achieve the design goal.
