基于IC卡的智能电能表设计毕业设计(论文).doc

摘 要 国家电网于2009年5月首次向社会公布“智能电网”发展计划以来，智能电网开始逐步的走进了人们的生活，智能电网作为未来电网发展的大趋势，在智能电网的改造和建设中，智能电力设备将会从中受益，智能电能表是智能电力设备中必不可少的设备，目前普遍采用的单相电能表技术虽然成熟，运行稳定，电能计量准确，但是其智能管理和安全必威体育官网网址性却很难满足智能电网建设和管理的需要，因此费控智能电能表的研发对智能电网的改造和建设具有重要的意义。 本文以低功耗高性能的ATMEL公司生产的Atmega16单片机为核心，配以ADI公司的高精度电量测量芯片ADE7755，SLE4442卡等外围电路设计的IC卡预收费电度表控制系统，采用硬件和软件相结合的方法，通过C语言编程实现IC卡在电表终端的持卡消费。本系统所涉及的主要内容有:IC卡的基础知识;硬件的选用、硬件设计和功能分析:主程序、掉电中断子程序、AT24C02读写子程序、SLE4442卡子程序和显示子程序的软件设计以及数据安全设计。通过对系统中涉及的硬件的选用和组合使整个系统的功耗和稳定性达到较好效果。通过对IC卡的选用和内部存储器的合理分配以及对程序的合理设计增强了IC卡中数据的安全性。 关键词：IC卡；电度表；ADE7755；单片机 Abstract Since the state grid first publicize the development plan of smart grid in May 2009, Smart grid steps into peoples life gradually, Smart grid as a trends of grid development in future, smart power equipment will benefit from the reform and construction of smart grid, smart electricity is a indispensable equipment of smart power equipment. The current poly-phase electricity although has the characters of mature technology, stable operation and power accuracy, but it defects in smart management and safety confidentiality, therefore the smart electricity will have the important significance of the reform and construction of smart grid. Based on low-power, high-performance production ATMEL Corporation Atmega16 as the core, coupled with ADIs high-precision measurement of electricity chip ADE7755.
