智能电能表大容量数据安全存储的方法研究

摘要

As a kind of electricity measuring instrument,the security of data storage in smart meters is quite important. With the publishment of OIML R46 international recommendation and more and more function used in smart meters,the method of large capacity data storage is needed.In this paper,the allocation of data storage is researched and the method of large capacity data storage in smart meters is presented,according to the characteristics of EEPROM and Flash and the importance of data storage in smart meter.The new method improves the efficiency and security of large capacity data stor-age,and extends the working life of storage.Meanwhile,it controls the cost of production effectively.%智能电能表作为一种电能计量器具,其数据存储安全十分重要.随着OIML R46国际建议的推行和智能电能表功能越来越丰富,对大容量电能数据存储提出了新的要求.从EEPROM及Flash数据保存特点出发,结合电能存储数据的重要性,研究了智能电能表的数据存储器分配,提出了一种智能电能表的大容量数据存储方法,提高了数据的存储效率,扩展了存储器的使用寿命,并且大大提高存储数据的安全性,同时在成本上得到了有效控制.
