摘 要
传统的电费管理都是由工作人员手工查表,抄表完成的,其中要完成用户电费的收取,每月抄度,用户购电情况查询,以及列出欠费用户的信息名单,之类的信息.其工作强度大,工作流程繁琐,由于工作人员的不细心,将会造成电费收支的出错也是经常发生的.鉴于以上原因我们有必要开发一种帮作电费管理人员的软件系统,可以完成检查用户用电情况,每月抄度,信息录入以及基本数据维护的各项功能.本系统采用visual basic 6.0与微软Access数据库方式.界面尽量做到人性化,数据维护方面做到可靠安全.-Abstract
The traditional electricity management manual look-up table by the staff, meter reading done, which collect to complete the consumer tariff, the monthly copy degrees, users buy electricity check, and a list of delinquent user information list, the class information. their work intensity, work processes cumbersome, due to staff not careful, will result in tariff revenue and expenditure of the error is a common occurrence. For these reasons we need to help develop a management software for electricity system, the user can complete the inspection of electricity consumption, monthly copy degree, information, and basic data entry to maintain the function. In this system, visual basic 6.0 and Microsoft Access database mode. interface of human nature as far as possible, data maintenance done reliable and secure.
