基于区块链技术的电力用户窃电电子证据可信存证系统设计

Design of a credible storage system for electronic evidence of power users stealing electricity based on blockchain technology

目前设计的电力用户窃电电子证据可信存证系统在出现拜占庭节点时,难以实现可信存证。为了解决上述问题,基于区块链技术设计了一种新的电力用户窃电电子证据可信存证系统,对系统的硬件和软件进行实验对比。系统硬件主要设计了采集模块、控制模块、数据存储模块、网络传输模块,采集模块主要设备是Campbell生产的CR800数据采集器,控制器采用TM4C123BE6PZ微控制器,以及AMPHENOL公司生产的MIL-DTL-38999Ⅲ连接器。利用区块链的链状结构进行可信存证,通过采集窃电电子证据指纹、打包窃电电子证据指纹、验证打包电子证据可信性实现软件流程。实验结果表明,设计的基于区块链技术的电力用户窃电电子证据可信存证系统在出现一个拜占庭节点的情况下,能够很好地实现可信存证。

The currently designed electronic evidence credible storage system for electricity theft by power users is difficult to achieve reliable storage in the presence of Byzantine nodes.In order to solve the above problems,a new electronic evidence credible storage system for electricity theft by power users was designed based on blockchain technology,and the hardware and software of the system were experimentally compared.The system hardware mainly consists of a collection module,control module,data storage module,and network transmission module.The main equipment of the collection module is the CR800 data collector produced by Campbell,and the controller uses the TM4C123BE6PZ microcontroller,as well as the MIL-DTL-38999 III connector produced by AMPHENOL company.Using the chain structure of blockchain for trusted storage,the software process is achieved by collecting electronic evidence fingerprints for theft,packaging electronic evidence fingerprints for theft,and verifying the credibility of packaged electronic evidence.The experimental results show that the designed blockchain technology based electronic evidence trustworthiness storage system for power user theft can effectively achieve trustworthiness storage in the presence of a Byzantine node.
