摘　　要：针对信号产品严重依靠进口技术,国产信号设备严重匮乏的现状,提供一种车载接口设备及其数据采集处理方法,旨在能与列车、轨旁信号设备进行接口,获取列车状态信息和位置信息,为车载ATC(列车自动控制)系统提供必要的输入,同时接收车载ATC主控单元的指令,发送到列车线,控制列车的运行。介绍了该车载接口设备的工作原理、功能、设备结构和软件逻辑。Since the present signal products rely heavily on imported technology because of the serious shortage of do- mestic signal equipment, an on-board interface device, a method of data acquisition and processing are introduced for the connection between the train equipment and the trackside equipment, so as to obtain the information of train status and location, to provide the necessary input for the on-board ATC system, at the same time to receive the instructions of the main control unit of the on-board ATC system, sending them to the train for the control the train operation. The working principles, the functions, the equipment structure and the software logic of the on-board interface device are introduced in details.
