Blockchain-based automatic measurement asset data quality detection system

传统基于大数据、全寿命周期的计量资产数据质量检测方法,受环境和数据存储不安全问题影响,导致检测精准度偏低,提出基于区块链技术的计量资产数据质量自动检测系统。区块链智能检测设备连接区块链上位机,接收被检测部件的参数信息。通过上位机存储模块获取采集节点地址信息和所检测部件的相关参数信息,利用CS5480计量芯片获取电网实际测量值。通过网络接口接收上位机发送的数据,实现自动比对。建立数据库,实时采集日志文件,以用户属性信息为基础,获取预设阈值和特征参数,判断所获取数据的异常情况。由实验结果可知,该系统在电磁干扰环境下,检测精度最低为80%;在数据存储不安全情况下,检测精度最低为96%,能够得到精准的检测结果。

The traditional measurement asset data quality detection methods based on big data and life cycle are affected by the environment and data storage insecurity,resulting in low detection accuracy.This paper proposes an automatic measurement asset data quality detection system based on blockchain technology.The blockchain intelligent detection device is connected to the upper computer of the blockchain and receives the parameter information of the detected components.The address information of the acquisition node and the relevant parameter information of the detected components are obtained by the upper computer storage module,and the actual measured value of the power grid is obtained by CS5480 metering chip.Through the network interface to receive the data sent by the host computer,automatic comparison is realized.The database is established and the log files are collected in real time.Based on the user attribute information,the preset threshold and characteristic parameters are obtained to judge the abnormal data.The experimental results show that the detection accuracy of the system is 80%in the electromagnetic interference environment,and 96% in the case of unsafe data storage.
