Design of video image storage system for power users stealing electricity based on blockchain

为避免电网主机记录的电力用户窃电视频图像的色度水平与真实图像色度水平出现较大偏差,影响视频图像信息的真实存储,设计基于区块链的电力用户窃电视频图像存储系统。根据I2C总线配置原则,设置嵌入式微处理器与视频信号转换模块的实时连接关系,实现电力用户窃电视频图像存储系统的硬件环境搭建。在此基础上,部署关键区块链节点,利用FPGA程序编译的处理方法,规划视频图像信息的存储模式,实现系统的软件执行环境搭建,结合相关硬件设备,完成存储系统设计。实验结果显示,与多核架构型存储系统相比,在区块链技术支持下,电网主机记录的电力用户窃电视频图像色度值更接近其真实色度水平,符合真实存储视频图像信息的实际应用需求。

In order to avoid the large deviation between the chromaticity level of the power user stealing video image recorded by the power grid host and the chromaticity level of the real image,which affects the real storage of video image information,a power user stealing video image storage system based on blockchain is designed.According to the I2C bus configuration principle,the real⁃time connection relationship between embedded microprocessor and video signal conversion module is set up to realize the hardware environment of power user stealing video image storage system.On this basis,key blockchain nodes are deployed,the storage mode of video image information is planned by using the processing method of FPGA program compilation,the software execution environment of the system is built,and the storage system design is completed in combination with relevant hardware equipment.The experimental results show that compared with the multi⁃core rack configuration storage system,with the support of blockchain technology,the chromaticity value of the power user’s power stealing video image recorded by the power grid host is closer to its real chromaticity level,which meets the practical application requirements of real storage of video image information.
