摘要
IC卡电表的广泛应用，极大的方便了用户和电力公司，节约了劳动力，减去了收电费和交电费的许多麻烦，但同时，由于IC电表的设计方面的遗漏，其报警功能还是不能达到用户的满意程度。在这个大背景下，我们选择“IC卡电表欠费预报系统的设计”这个课题，希望能够对IC电表领域有所贡献。
由于该设计需要解决的是一个日常生活的实际问题，系统具有很强的社会应用性，所以，在系统的设计中，实现系统功能，降低系统成本是设计的指导思想。预交费IC电表在预存电量剩余为一定值时，LED发光告警。由于住宅小区整个楼层或整栋楼的用户电表集中在一个电力柜中，用户观测告警信号很不方便。为了使用户方便读取欠费告警信号，同时不改动现有公用设施的状态，系统采用单片机为控制模块，电力线载波通讯模块为传输模块，利用电力线做传输介质。

ABSTRACT
IC card electricity meter extensive use, extremely large convenient consumer and electric power company, has saved a labour force, subtractive an awful lot of trouble collecting electric charge and delivering electric charge, is but simultaneous, since IC electricity meter design aspect leaving out , it's the function giving an alarm are still the satisfied degree being able to not reach a consumer. Under this big background, we choose "the IC card electricity meter owing forecasting system-consuming design" this problem, hope is able to make contribution to IC electricity meter field.
Since should design the actual problem requiring that solving is a daily life, system has the very strong society applicability, reason why, realizing system function, reducing system cost in systematic design, is the guiding ideology designing that. Deliver IC-consuming electricity meter in advance reporting an emergency in prestore quantity of electric charge surplus for LED gives out light when certain value. Since the entire storey of housing district or the entire ridgepole building consumer electricity meter concentrates alarm on a electric power chest middle, the consumer observes do not go to the lavatory very much. For making a consumer convenient fetch owe alarm-consuming , not changing the state now having public facilities at the same time, system adopt the monolithic machine to be under the control of module , the electric line of force carrier wave communication module is to transfer a module , make use of an electric line of force to do transmission medium.
