The invention discloses a multi-source information fusion positioning and timing preview control method based on locomotive line visibility. The method comprises the following steps: acquiring locomotive line position, speed and acceleration information through a position and speed sensor, and then, abstracting a multi-source information feature vector; with a neural network being used as a classifier, distinguishing different driving types and complex driving information in a feature layer, and providing a good basis for final information fusion diagnosis; carrying out information fusion on the distinguished driving information and a locomotive visible line; and performing high-precision preview control on locomotive timing and positioning based on multi-source information fusion. Predictive control is carried out on timing and positioning of the locomotive with high precision, locomotive motion information can be rapidly transmitted to a control program in time, and rapid response ofautomatic driving of the locomotive is facilitated.
本发明公开了一种基于机车线路可见的多源信息融合预见定位定时控制方法。它包含以下步骤:通过位置和速度传感器获取机车线路位置、速度、加速度信息,然后抽象出多源信息特征向量;以神经网络为分类器,在特征层将不同的驾驶类型与复杂的驾驶信息区分开来,为最终的信息融合诊断提供良好的基础;将区分后的驾驶信息与机车可见线路进行信息融合;基于多源信息融合对机车定时定位进行高精度预见控制。本发明以高精度对机车定时定位进行预见控制,可以及时将机车运动信息快速传输给控制程序,有利于机车自动驾驶的快速响应。
