Architecture for collecting traffic accident information based on block chain, and working method

Abstract

The patent provides architecture for collecting traffic accident information based on a block chain, and a working method. The architecture comprises three layers: a cloud service layer, an edge computation layer and a sensing layer; the sensing layer comprises a vehicle and a roadside unit, the vehicle and the roadside unit commonly form a block chain network; the edge computation layer providesa computation resource for the sensing layer so as to accomplish consensus task; the service layer comprises cloud service and the block chain; the working method based on the architecture comprises four steps: traffic accident information querying, traffic accident information returning, roadside unit consensus and traffic accident information storage. By adopting the block chain technology, thetraffic accident information cannot be tampered and is traceable, thereby providing powerful evidence for the traffic department; by adopting the edge computation technology, the task with large computation quantity is unloaded to the edge network from the roadside unit, the burden of the roadside unit is relieved, and the efficiency of collecting the traffic accident information is improved.

Description

technical field [0001] The patent of the present invention relates to a blockchain-based architecture and working method for collecting traffic accident information, which belongs to the field of information processing. Background technique [0002] The most important thing to deal with traffic accidents is to collect traffic accident information. At present, there are two main methods of collecting traffic accident information, manual and automatic. These methods take a long time and cause certain difficulties to quickly record the scene, quickly evacuate traffic, analyze the accident after the event and determine the responsibility. Drive recorder is the instrument of the video image and sound in recording vehicle traveling process, can provide powerful evidence for handling traffic accident. Although many vehicles are equipped with driving recorders at present, there is no function of uploading the recorded video to the network, and it is only stored locally. [0003]...

AI Technical Summary

Problems solved by technology

Although many vehicles are currently equipped with driving recorders, they do not have the function of uploading the recorded video to the network, but only save it locally.
