摘要
本文首先对数据库设计E-R方法的原理作了简单阐述,然后依据E-R方法及管理信息系统开发的一般规则,对电力系统继电保护设备进行了详细的分析和研究,并用FOX-PRO2.5和C语言在DOS系统下编程实现。本文对该系统的功能和实现方法,以及其方便的帮助功能作了简述。该系统运行速度快,代码质量高,人机界面良好,且操作灵活,提示丰富,应用性强。只须稍加修改就可推广至电力系统其他专业,具有较大的实用价值和推广价值。
This paper simply describes the principle of E--R method for database design,and then analyzes and studies the relay protectiveequipment of power system according to the E--R Inethod and the general rule of management information system development.The information system is programmed in FOXPRO2. 5 and C language under Ic)S system. The functions and realization methodof the Information system as well as its convenient help function are simply introduced. The system features quick operation speed,high code quality, friendly man -- machine interface. sensitive operation, rich prompt, and stronger applicability. After slightchange,it can be spread to IJOwer system or other Industrial fields. So it is very valllable to apply and spread.
