Abstract

The invention discloses a dual-machine hot standby train automatic operation (ATO) system. The system comprises ATO systems independently configured at a head end and a tail end. The ATO system at each end comprises an ATO system A machine, an ATO system B machine, an arbitration device and a parallel output control unit, wherein the ATO system A machine and the ATO system B machine both employ independent input output ports, perform real-time self-examination and send a self-examination result to the arbitration device; the arbitration device is used for determining the working states of the ATO system A machine and the ATO system B machine according to the received self-examination result and selecting a main device from the two machines; and the parallel output control unit is used for a train control instruction outputted by the main device to a train control interface. By using the system disclosed by the invention, the heat standby redundancy switching of the ATO system is realized, and the system safety is improved.

Description

technical field [0001] The invention relates to the field of urban rail transit, in particular to a dual-machine hot-standby train automatic driving system. Background technique [0002] With the rapid development of urban rail transit and information technology, the technical level of urban rail transit signal control system is constantly being updated. Among them, the development and application of train automatic driving technology is a typical representative. The automatic train driving subsystem (ATO for short) can reduce the labor intensity of the driver, improve the comfort of train operation, and reduce the energy consumption of train operation. In the current rail transit construction, the train automatic driving subsystem has been generally configured, and most of the new lines have realized the direct opening of the automatic driving function. [0003] The role of train automatic driving subsystem in train operation is becoming more and more important, and new r...
