The invention discloses a method for calculating the distance of a front annunciator. The method comprises the following steps: drawing a train working diagram on a screen according to LKJ basic data; judging whether the LKJ basic data contains a short chain or not, and if yes, removing the pixel length of the short chain when the train working diagram is drawn; judging whether the LKJ basic data contains a long chain or not, and if yes, increasing the pixel length of the long chain when the train working diagram is drawn; calculating a pixel difference value between the locomotive and the front annunciator according to the pixel of the real-time running position of the locomotive and the pixel of the front annunciator in the screen; and calculating a real distance value corresponding to the pixel difference value, wherein the real distance value is the real distance between the real-time position of the locomotive and the front signal machine.

    本发明公开了一种计算前方信号机距离的方法,依据LKJ基础数据在屏幕上进行列车运行图的绘制;判断LKJ基础数据中是否包含短链,若包含,则在绘制列车运行图时去掉短链的像素长度;判断LKJ基础数据中是否包含长链,若包含,则在绘制列车运行图时增加长链的像素长度;依据屏幕中机车实时运行位置的像素与前方信号机位置的像素计算出机车与前方信号机之间的像素差值;计算所述像素差值对应的真实距离值,所述的真实距离值即为机车实时位置距离前方信号机的真实距离。
