摘要
为了解决电能表系统数据现场升级程序容易出现数据混乱的问题,分析了目前电能表系统数据存储的方式,针对目前电能表系统数据存储的问题提出了改善方案。通过数据链表创造出一个可以自由伸缩的数据存储系统,形成了以数据块为存储单元的存储模式,解决了电能表系统中新增加数据会导致现有数据地址改变的问题。文章先从目前电能表系统数据存储的问题说起,随后提出了新的数据存储模型,并一一介绍了新数据存储模型的创建、读取、写入及删除等操作,并在电能表上成功实现了新数据存储模型。
In order to solve the problem that data field update watt-hour meter system prone to data corruption,this paper analyses the current watt-hour meter system of data storage,and puts forward an improvement proposal based on the problem of the current meter system data storage.Through the data link to create a free scalable data storage system,a data block storage mode is formed,thus the poblem that the new data can lead to the existing data address change can be solved.In this paper,the problem in current watt-hour meter data storage system is mentioned firstly,then a new data storage model is put forward,and the create,read,write,and delete operations of the new data storage model are introduced.The new data storage model is implemented on the watt-hour meter.
