Bidirectional train control method and device and computer readable storage medium

Abstract

An embodiment of the invention discloses a bidirectional train control method and device and a computer readable storage medium. Bidirectional control of a train line is realized under the condition that communication cables among logic control units are not increased additionally. The method comprises the steps as follows: a level transmission direction signal is added to the current logic control unit; when the current logic control unit unlocks the level transition direction, the signal form of the direction signal is adjusted according to input conditions of level signals at two input endsof the train line of the current logic control unit; when the train line function of the current logic control unit locks the transmission direction, levels of output ends corresponding to the inputends are adjusted according to the direction type of the direction signal and a control command, so that levels of the output ends of the current logic control unit are matched with the direction signal; the level signal of a target output end is transmitted to an input end of the next logic control unit. The working mode of the current logic control unit is referred, and ordered control of the whole bidirectional train can be realized.

Description

technical field [0001] The invention relates to the technical field of rail transit, in particular to a two-way train control method, device and computer-readable storage medium. Background technique [0002] At present, a large number of relays are used in the control loop of rail transit vehicles as the control elements of the control loop. The relay is composed of a coil and a contact. The electrified control coil can change the open and closed state of the contact, so as to realize the vehicle control function. However, due to the problems of short life, easy aging, and contact adhesion of the mechanical contacts of the relay, the application of the non-contact control technology of the Logical Control Unit (LCU) has also been put on the agenda. [0003] The input and output of the LCU are two sets of independent circuits. After the input signal is collected by the input board, after the operation is completed by the logic control unit, the result is output by the outpu...

AI Technical Summary

Problems solved by technology

When the LCU is used to collect the input in two directions and transmit the output to the next vehicle, it is necessary to correctly handle the logic control used in parallel connection of the input and output. If the logic is not handled correctly, the output signal of one road will be fed back to the other input. May make the whole circuit wrongly energized, resulting in wrong control of the train
