The invention discloses a safe vehicle distance automatic recording and evidence obtaining system based on data analysis, relates to the technical field of vehicle distance safety monitoring, and aims to solve the problems that in the prior art, evidence obtaining time of evidence obtaining videos cannot be accurately determined, the evidence obtaining videos cannot be intelligently intercepted according to actual conditions, and the evidence obtaining efficiency is high. The problem that the intercepted evidence obtaining video is incomplete or overlong and occupies a memory is solved; comprising a data acquisition module, a vehicle distance analysis module, a forensic storage module and a forensic analysis module, analyzing the vehicle distance information and the vehicle speed to obtain an evidence obtaining picture and evidence obtaining time, and performing video interception according to the evidence obtaining picture and the evidence obtaining time to obtain an evidence obtaining video; meanwhile, whether traffic jam exists or not is judged, if traffic jam exists, evidences in circulation time are filtered, and repeated and redundant evidences are avoided; according to the method, the evidence obtaining number and the corresponding time periods are counted and analyzed, the evidence obtaining high-incidence time periods and the evidence obtaining high-incidence road sections are obtained, warning frequency optimization operation is conducted on the evidence obtaining high-incidence time periods and the evidence obtaining high-incidence road sections, and the vehicle distance keeping prompting effect can be effectively achieved for a vehicle driver.

    本发明公开了基于数据分析的安全车距自动记录取证系统,涉及车距安全监测技术领域,用于解决目前技术无法对取证视频的取证时间进行准确确定,不能根据实际情况做出智能截取取证视频,造成截取的取证视频不全或者过长占据内存的问题;包括数据采集模块、车距分析模块、取证存储模块和取证分析模块;通过对车距信息和车速度进行分析得到取证照片和取证时间,并据此进行视频截取得到取证视频;同时判断是否存在堵车,若存在堵车则流通时间内的取证进行过滤,避免造成重复多余的取证;统计取证数量和对应的时间段进行分析,得到取证高发时间段和取证高发路段,并对其进行警示语频次优化操作,能够有效地对行车驾驶人员进行保持车距的提示作用。
