Automatic vehicle head switching judgment method and device based on equivalent direction of route map

The invention relates to a vehicle head switching automatic judgment method and device based on a line map equivalence direction. The method comprises the following steps: step A, constructing a static line map equivalence direction; b, calculating an equivalent direction of a train head; c, calculating a train head number Cab ID; and D, automatically judging whether the train head of the train is switched or not. Compared with the prior art, the method has the advantages of less required information, high judgment speed and the like. 本发明涉及一种基于线路地图等价方向的车头切换自动判断方法及装置，该方法包括以下步骤：步骤A：构建静态线路地图等价方向；步骤B：计算列车车头等价方向；步骤C：计算列车车头编号Cab ID；步骤D：自动判断列车是否切换车头。与现有技术相比，本发明具有所需信息少、判断速度快等优点。
