Abstract
Automatic meter reading means the use of communications and computer network technologies such as automatic meter reading and processing data. The development of automatic meter reading technology is the power to raise the level of power management needs, and it is also inevitable for the network and computer technology rapid development. In power management, the use of automatic meter reading technology, will not only save human resources and, more importantly, to improve the accuracy of meter reading, or to reduce the estimated billing errors caused by transcription, so that power management for timely and accurate access to data and information. So as a result of electricity users who no longer need an appointment with the door-to-door meter reading meter reading time, billing inquiries can quickly, so this technology more and more users.
Area residents to use a variety of automatic meter copy and remote transmission, the realization of the true meaning of the Intelligent Community of the fast, efficient, safe and user-friendly features, the article of the existing system of automatic meter reading problems to do with the lack of a analysis. Then, It introduced the residential developments of the intelligent automatic meter reading system.
This paper introduces the area of the development of the smart meter reading system, and then introduced a single-chip microcomputer system in the field of application and development, and designed a single-chip cell-based smart meter reading system, and introduced the system the choice of hardware and system design process, and finally with the Keil software system simulation.
Key words：Smart meter reading system Single-chip Automatic meter reading keil Software摘 要
自动抄表是指采用通讯和计算机网络等技术自动读取和处理表上所记数据。发展电能自动抄表技术是提高用电管理水平的需要，也是网络和计算机技术迅速发展的必然。在用电管理方面，采用自动抄表技术，不仅能节约人力资源，更重要的是可提高抄表的准确性，减少因估计或誊写而造成的帐单出错，使供电管理部门能及时准确获得数据信息。因此电力用户不再需要与抄表者预约上门抄表时间，还能迅速查询帐单，故这种技术越来越受到用户欢迎。
为了对小区用户使用的多种计量表具进行自动抄录和远程传输,实现智能小区真正意义上的快捷、高效、安全、方便的功能,本文对现有的自动抄表系统存在的问题与不足做了分析。然后介绍了智能小区自动抄表系统的发展趋势。
本论文首先介绍了小区智能抄表系统的现状，然后介绍了单片机系统在这个领域的应用和发展情况，设计了基于单片机的一个小区智能抄表系统，并介绍了该系统的硬件的选择和系统的设计过程，最后用Keil软件对该系统进行了仿真。
