智能电表的硬件设计 [摘 要]随着社会的发展和进步，电能变得越来越紧张，合理利用电能就成为急待解决的问题，为了提高供电质量和资源的合理利用，必须抑制高峰需求，鼓励低谷用电，这就需要运用价格的杠杆作用，制定峰谷分时电价来调节。所以，就需要有一个智能的计费工具，来实现价格调节——智能分时计费电度表。本设计通过单片机以及I 2C串行总线使很好的对峰谷进行分时记值、计价，从而很好的解决了电能收费问题。本文给出了智能分时计费电度表硬件设计的基本思路。给出了整体电路的原理、设计图和几个电路使用特殊芯片和使用硬件资料，是实用性很强的设计方案。 [关键词]单片机；分时计费； The Hardware Design of Intelligent Electric Meter Abstract：With the development and progress of society, the electric energy is becoming more and more intense , the rational utilization of energy has become urgent to solve the problem, in order to improve the power supply quality and reasonable utilization of resources, must restrain the peak demand, encourage the underestimation of electricity, this needs to use the leverage of the price, make electrovalency of peak cereal time-sharing to adjust. So, you need to have an intelligent charging tool, to achieve price adjustment—intelligent time-sharing accounting of kilowatt-hour meter. Through the design of Single chip microcomputer and Inter-Integrated Circuit serial bus makes good on peak-valley time-sharing note value, valuation, which well solves the problem of electricity charges. This paper presents the intelligent Time-sharing Accounting of kilowatt-hour meter hardware the basic idea of the design. The whole circuit principle, design and several circuit using special chips and the use of hardware, is very practical design scheme.
