基于嵌入式的电量计量采集系统研究

Research of Electric Quantity Measurement and Acquisition System Based on Embedded System

摘要:

考虑到目前电量计量采集系统线路布置复杂，针对窃电行为的监测和判断能力弱，本文研究一种基于嵌入式的电量计量采集系统。嵌入式电量计量系统的构成有两部分：高压侧用电信息无线监测装置和低压侧用电信息远程监测装置。高压侧用电信息无线监测装置的工作原理为对高压侧的电路信息进行采集，之后通过发射模块将信息传递至远程监控单元，监测人员可通过监控中心直接对电路信息进行远距离实时读取。低压侧用电信息远程监测装置对各个用电用户的用电信息进行直接识别，而后将识别分析结果输送到监控主站的信息库中。实验结果表明：高压无线检测装置检测到的数据通过换算后得到的用户用电情况曲线却不能和低压侧无线检测装置得到的数据曲线重合，说明该装置能够检测到人为窃电操作，验证了本文研究的嵌入式电量计量采集系统能够实现窃电的精确识别。

Abstract:

Considering the complex circuit layout of the current electricity measurement and acquisition system and the weak ability of monitoring and judging electricity theft, this paper studies an embedded electricity measurement and acquisition system. There are two parts in the embedded power metering system: wireless monitoring device for high voltage side power consumption information and remote monitoring device for low voltage side power consumption information. The working principle of the wireless monitoring device for high-voltage side electrical information is to collect the circuit information on the high-voltage side, and then transmit the information to the remote monitoring unit through the transmitting module. The remote monitoring device of low-voltage side power consumption information directly identifies the power consumption information of each user, and then transmits the result of identification analysis to the information database of the monitoring main station. The experimental results show that the data detected by the high-voltage wireless detection device can not coincide with the data curve obtained by the low-voltage wireless detection device, which shows that the device can detect the operation of human power theft, and verifies that the embedded power metering and acquisition system studied in this paper can be implemented. Accurate identification of stealing electricity.
