摘要
我国高速公路设置ETC门架系统实现了对车辆分段计费,这使得高速公路车辆通行数据更加零散,对稽查管理提出了挑战。为解决此问题,基于联盟链超级账本技术,提出了一种适用于高速公路通行数据共享的区块链。使用链码实现通行数据的快速上链,在保证业务逻辑完整性的同时,完成数据共识的快速判断和有效实现。实验结果表明,该方案可以有效实现高速公路车辆通行记录的数据共识,实验系统的系统吞吐率可满足片区级别高速公路通行数据应用的性能需求。
ETC gantry system is set up on the freeway in China to realize the segmented charging of vehicles,which makes the traffic data of freeways more scattered,and challenges the inspection management.In order to solve this problem,based on the Hyperledger technology of consortium blockchain,a block chain suitable for freeway traffic data sharing is proposed.The chain code is used to ensure the integrity of business logic and complete the fast judgment and effective implementation of data consensus.The experimental results show that the scheme can effectively achieve the data consensus of freeway vehicle traffic records,and the system throughput of the experimental system can meet the performance requirements of freeway traffic data application at the district level.
