Automatic train driving system based on double-system hot standby redundancy

Abstract

The invention relates to an automatic train driving system based on double-system hot standby redundancy. The system comprises two automatic driving systems connected with a train, wherein each automatic driving system comprises a power source, an input module, a control module, a switching module and an output module, the power source supplies power for all equipment of the system, the input module is used for acquiring input information of vehicles and sending the input information to the control module, the control module communicates with an automatic protection system and a record system of the train and monitors states of the power source, the input module, the switching module, the output module and the control module itself of the location system, the switching module is used for evaluating a work state of the location system and carrying out system switching according to the practical state, and the output module outputs a control command to the train. The system, through multiple redundancy measures, improves reliability of the automatic driving systems and reduces influence of a system fault on main line operation.

Description

technical field [0001] The invention relates to the technical field of train control, in particular to a train automatic driving system based on dual-system hot standby redundancy. Background technique [0002] With the increase of subway passenger flow, the requirements for line operation efficiency are gradually increasing. Manual driving can no longer meet the operation needs of high-density subway lines. At present, the on-board signal equipment of most domestic subway lines is equipped with automatic train driving system (ATO). figure 1 A typical ATO system structure diagram of the prior art of the present invention is shown, with reference to figure 1 , ATO obtains relevant security information such as train movement authorization, speed measurement and positioning from the automatic train protection system (ATP), combines the input information collected from the vehicle, completes the calculation of automatic control commands such as target curves and traction braking...

AI Technical Summary

Problems solved by technology

[0003] The increase in the utilization rate of ATO has put forward higher requirements for its system reliability and availability. The traditional ATO system operated by a single system is a single point of failure in key control links such as input acquisition, target curve and control command calculation, and control command output. Once a fault occurs during the main line operation of the train, it is difficult to recover the fault during the online operation, and only manual driving can be used before the train ends operation, which will affect the operation in terms of fault recovery, line operation efficiency, passenger comfort, parking at the station, etc. Negative impact
