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

Electricity from the traditional management staff are artisanal Chabiao, meter reading completed, which should be completed by the users of electricity per month penalty for users to buy electricity enquiries, and a list of user information channels list such information. Its work-intensive, cumbersome workflow, because staff are not careful. would result in the tariff revenue is recurring mistakes. Given the above reasons we need to develop a management software to help make electricity system, the user can complete the inspection of electricity monthly copied degrees, Information includes basic data and the maintenance function. with the system using visual basic Microsoft Access 6.0 database. as far as possible humanization interface, data maintenance to reliable security.

第一章 引言
1．1 课题背景
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.

1．2 系统简介
本系统主要由以下几大功能模块组成:
一. 用户交费:(交纳电费,本日小节)
二. 本月抄度:(单户抄度 多户抄度)
三. 资料导出 (全部清单,欠费清单)
四. 数据查询 (电费查询与统计,用户欠费查询)
五. 信息录入 (资料录入,资料修改, 资料删除)
六. 系统数据维护 (数据备份,数据恢复)
七. 基本数据维护 (用户类型维护, 操作员维护)
八. 帮助
九. 退出

第二章 系统的分析

2．1 系统开发的目标和思想
本系统主要服务于电费管理人员的日常工作.设计思路主要参照工作人员抄表,记录资料,资料管理,信息录入等方面的工作流程展开的.

2．2 系统的可行性分析
本系统采用visual basic6.0与微软的access作为数据库结合.在系统编写上具有可行性.
经济方面:本系统可以服务电厂,电费管理单位,为企业节省人力开支.
社会方面:服务于大众,方便抄表人员工作,可靠方便.
