摘　　要：本文介绍的预付费电子电度表是由美国Ｍｏｔｏｒｏｌａ公司生产的单片机ＭＣ６８ＨＣ７０５Ｌ１和外围电路组成的。该表降低了计算盲区，提高了电度表的精度。使用ＩＣ卡作为预付费的工具，给电业部门的现代化管理提供了必要的条件。In This paper, the electronic watt hour meter with predictive delivery cost is introduced, it is composed of chip microcomputer MC68HC705L1 of Motorola Co. in U.S.A. and external circuit. This meter reduces the blind area and improves precision of watt hour meter. The IC card has become the tool of predictive delivery cost, hance it provides the necessary condition for modern management of electric department.
