Simulation tracking self-recovery method for communication failure locomotives in locomotive dispatching monitoring system

Abstract

The invention relates to a simulation tracking self-recovery method for communication failure locomotives in a locomotive dispatching monitoring system. The method includes the following steps that: 1) when the head of a train set performs trans-section operation, an onboard unit records trans-section information with a fixed format in real time into a power-down protection memory; 2) after communication between an on-board host and a ground host fails, if the ground host operates normally, and a locomotive section position is simulated and tracked according to station yard element connectionrelationships and interlocking code position change information; 3) after the communication failure of the on-board host and the ground host is recovered, the on-board host judges whether a locomotivemeets a fault recovery condition, and the on-board host initiates a self-recovery network access application to the ground host if the locomotive meets the fault recovery condition; 4) after the ground host receives the self-recovery network access application of the on-board host, the ground host judges the validity of network access information, and the ground host sends the simulated and tracked section position information to the on-board host if the network access information is valid; and 5) after the on-board host receives the section position information of the ground, the on-board host calculates the specific position of the head of the train set. Compared with the prior art, the method of the invention has the advantages of low cost, high availability, and security.

Description

technical field [0001] The invention relates to a shunting monitoring system, in particular to a simulation tracking self-recovery method for a locomotive with a communication fault in the shunting monitoring system. Background technique [0002] During the shunting operation in the station, it is often encountered that the operation is carried out under bridges and tunnels where the radio signal is interrupted or in areas where the radio signal coverage is weak. Due to the blockage of the radio signal, the train-ground communication is interrupted and the locomotive withdraws from the monitoring. [0003] In the existing shunting monitoring system, in order to solve this problem, the method of adding a relay station is generally adopted. This method needs to consider issues such as the installation location of the relay equipment, equipment power supply, and cable laying. and maintenance costs; in some stations where the environment is complex and not suitable for installin...

[0002] During the shunting operation in the station, it is often encountered that the operation is carried out under bridges and tunnels where the radio signal is interrupted or in areas where the radio signal coverage is weak. Due to the blockage of the radio signal, the train-ground communication is interrupted and the locomotive exits the monitoring

[0003] In the existing shunting monitoring system, in order to solve this problem, the method of adding a relay station is generally adopted. This method needs to consider issues such as the installation location of the relay equipment, equipment power supply, and cable laying. and maintenance costs; in some stations where the environment is complex and not suitable for installing relay equipment, after the communication is interrupted, the car can only be controlled manually, and the standby car runs to the area where the signal is normal. automatic network access

In addition, there is currently no practical and effective self-recovery method for locomotives with communication failures
