The invention discloses a traffic signal control method and device based on a block chain technology, and the method comprises the steps: packaging a traffic signal controller number and a traffic signal control scheme through a traffic signal control platform, transmitting the packaged traffic signal controller number and traffic signal control scheme to a first block chain sidecar module, and enabling the first block chain sidecar module to broadcast a packet message to a traffic signal controller; the second block chain sidecar module receives the packet message broadcasted by the first block chain sidecar module, verifies the packet message and stores the packet message to the block chain; unpacking the number of the traffic signal controller and the traffic signal control scheme packed by the traffic signal control platform, and transmitting the unpacked number of the traffic signal controller and the traffic signal control scheme to the traffic signal controller; the traffic signal controller judges whether the unpacked traffic signal control scheme needs to be executed or not according to the unpacked traffic signal controller number, and if yes, the traffic signal controller executes the unpacked traffic signal control scheme. According to the invention, the safety of a traffic signal control scheme is improved.

    本发明公开了一种基于区块链技术的交通信号控制方法及装置,通过交通信号控制平台将交通信号机编号和交通信号控制方案打包后传送给第一区块链sidecar模块,并由第一区块链sidecar模块向交通信号机广播包消息;第二区块链sidecar模块接收第一区块链sidecar模块广播过来的包消息,验证并将包消息存储至区块链;对交通信号控制平台打包的通信号机编号和交通信号控制方案进行拆包,并将拆包的交通信号机编号和交通信号控制方案传送给交通信号机;交通信号机根据拆包的交通信号机编号,判断拆包的交通信号控制方案是否需要执行,若是,则交通信号机执行拆包的交通信号控制方案。本发明提高了交通信号控制方案的安全性。
