The invention relates to the technical field of official business vehicle supervision, and particularly provides a virtual electronic fence-based access vehicle detection method, which comprises the following steps of: determining a fence area on an electronic map in response to a fence setting instruction; obtaining vehicle state information sent by the vehicle-mounted terminal; preliminarily judging the current position of the vehicle according to the fence external rectangular range, the fence internal rectangular range and the vehicle state information; if the vehicle is in the fence external rectangular range and is not in the fence internal rectangular range, whether the vehicle is in the virtual electronic fence range or not is judged according to the virtual electronic fence range and the vehicle state information; if the vehicle is not in the virtual electronic fence range, whether the vehicle just drives out of the virtual electronic fence range or not is judged according to the vehicle state information received last time; and if the vehicle is in the virtual electronic fence range, judging whether the vehicle just enters the virtual electronic fence range or not according to the vehicle state information received last time, so as to solve the problem that the detection efficiency of the access vehicle of the virtual electronic fence is relatively low.
本申请涉及公务用车监管技术领域,具体提供一种虚拟电子围栏的出入车辆检测方法,响应于围栏设置指令,确定电子地图上的围栏区域;获取车载终端发送的车辆状态信息;根据围栏外接矩形范围、围栏内接矩形范围和车辆状态信息初步判断车辆的当前位置;若车辆在围栏外接矩形范围且不在围栏内接矩形范围,根据虚拟电子围栏范围和车辆状态信息判断车辆是否在虚拟电子围栏范围;若车辆不在虚拟电子围栏范围,根据上一次接收的车辆状态信息判断车辆是否刚驶出虚拟电子围栏范围;若车辆在虚拟电子围栏范围,根据上一次接收的车辆状态信息判断车辆是否刚驶入虚拟电子围栏范围,以解决虚拟电子围栏的出入车辆检测效率较低的问题。
