The invention discloses a traffic flow collection system and method based on crowdsourcing and a blockchain. The method comprises the steps: setting a road segment collected by a traffic flow blockchain, the collection difficulty N of a block and generation time T through a blockchain system management side, and constructing and generating a blockchain creation century block for each road segment;a block chain user side is responsible for issuing crowdsourcing tasks for each road segment to a vehicle user side to realize generation of blocks, and the block chain user side meeting block generation conditions (including the acquisition difficulty N and generation time T) adds vehicle data records contained in the crowdsourcing tasks of the block chain user side into the block chain as a block; and the vehicle user side is responsible for submitting the data of the currently running vehicle as a vehicle data record to a crowdsourcing task. Traffic flow data acquisition is performed by means of the Internet and the intelligent terminal and in combination with crowdsourcing and blockchain technologies, and the method has the characteristics of low cost, high efficiency, accuracy, decentralization, no data tampering and the like.

    本发明公开了一种基于众包和区块链的交通流采集系统及方法,包括:由区块链系统管理端设定交通流区块链所采集的路段、区块的采集难度N及生成时间T,并构造生成针对各路段的区块链创世纪块;区块链用户端负责向车辆用户端发布针对各路段的众包任务以实现区块的产生,且由满足区块产生条件(包括采集难度N和生成时间T)的区块链用户端将其众包任务中所包含的车辆数据记录作为一个区块加入到区块链中;车辆用户端负责将当前正在行驶的车辆数据作为一条车辆数据记录提交到一个众包任务中。本发明借助互联网、智能终端,并结合众包和区块链技术进行交通流数据采集,具有成本低、高效、准确、去中心化、数据不可篡改等特点。
