基于规约编码和缓存的智能用电数据处理技术

针对智能用电信息采集系统的数据集中采集、数据项和用户数量大的特点,提出了一种基于编码的算法并结合缓存技术的批量数据入库的新技术。先对采集的数据项进行预编码,运用P/T映射技术将数据项和存储字段关联并映射到缓存中,通过内存寻址方式先缓存数据,再定时批量提交到数据库,减少了数据库的操作频率,提高了系统的数据入库效率和稳定性,介绍了其中的主要功能模块以及关键技术的实现。

Smart Electricity Consumption Data Processing Technology Based on Protocol of Encoding and Cache

According to the characteristics of smart electricity consumption data acquisition system： centralized data acquisition,large quantity of data items and customers,a new batch data loader technology is proposed which is based on coding algorithm and cache technology.The acquisition data items are precoded and then mapped into the cache data area using P/T data mapping technology,and batch submitted to the database at scheduled time to reduce the operation frequency of the database.The algorithm greatly enhances the system＇s data storage efficiency and stability.Finally,the main function modules and the realization of key technologies are introduced.
