The invention discloses a system and method for accurately judging vehicle traffic illegal behaviors, and the method comprises the steps that: a positioning module improves the positioning frequency of the positioning module when a vehicle carrying a vehicle-mounted intelligent terminal enters a beacon range of a beacon station; an industrial personal computer obtains the vehicle positioning data generated by the positioning module to construct a vehicle driving track; the industrial personal computer obtains the correction amount generated by the differential station; the industrial personal computer corrects the vehicle driving track according to the correction amount to generate a corrected vehicle track; the industrial personal computer obtains the road state and judges whether the vehicle breaks the rule or not according to the road state and the vehicle correction track, and when the vehicle leaves the range of the beacon, the positioning module reduces the positioning frequency of the positioning module. According to the method, whether the vehicle violates the rule or not is judged by judging the motion trail of the vehicle, the influence of interference factors such as weather and urban environment on the positioning precision is reduced, the power consumption is greatly reduced, and the service time of equipment is prolonged.
本发明公开了一种精准判断车辆交通违法行为的系统及方法,当携带有车载智能终端的车辆进入到信标站的信标范围时,定位模块的提高自身的定位频率;工控机获取定位模块所产生车辆定位数据以构建车辆行驶轨迹;工控机获取差分站所产生的修正量;工控机根据修正量对车辆行驶轨迹进行修正,产生修正车辆轨迹;工控机获取道路状态,并根据道路状态和车辆修正轨迹,判定车辆是否违规,当车辆离开信标范围时,定位模块的降低自身的定位频率。通过对于车辆运动轨迹的判断,进而判断车辆是否违规,减少了由于天气、城市环境等干扰因素对于定位精度造成的影响,并且极大的减少了功耗,延长了设备的使用时间。
