Title
(EN) Intelligent electric meter data storage method and device
(ZH) 智能电表数据存储方法及装置
Abstract
(EN) The invention relates to the technical field of intelligent electric meters, and especially relates to an intelligent electric meter data storage method and device. The method comprises the followingsteps: acquiring power utilization data and recording time nodes corresponding to the power utilization data; reading preset reference time and an electric meter recording period; carrying out byte compression on the recording time nodes according to the preset reference time and the electric meter recording period to obtain a time index; and associating the power utilization data with the time index and then storing the data. By means of the method, the storage pressure of curve data is reduced, and due to the fact that the calculation mode of the time index is simple, data storage and data query can be conducted at a high response speed.
(ZH) 本发明涉及智能电表技术领域,尤其涉及一种智能电表数据存储方法及装置。所述方法包括:获取用电数据和所述用电数据对应的记录时间节点;读取预设基准时间及电表记录周期;根据所述预设基准时间及所述电表记录周期对所述记录时间节点进行字节压缩,以获得时间索引;将所述用电数据和所述时间索引进行关联后保存。本发明通过上述方法,使得曲线数据的储存压力降低,由于时间索引的计算方式简洁,能以较快的响应速度进行数据存储及数据查询。
