Definitions

• the present disclosure relates to train signal control systems, and in particular, to a method for comparing the consistency between a general indication and an individual indication of a switch.
• the switch is a line connection device that enables train vehicles to transfer from one track to another, and it is one of the most critical devices in railway traffic signal equipment and also one of the weak links of the track.
• the switches in the route must be in the correct position.
• the interlocking system uses the collected switch positions as determination conditions for route setting and signal clearing to ensure that all switches passed by the train during operation are in the correct position. A false determination of the switch position may easily lead to serious safety accidents.
• the position determination of speed-up multi-stage traction switches and double-acting/multi-acting switches is more complex.
• CN116039711A discloses a method and an apparatus for checking a position of a large switch by an interlocking system, and a medium.
• the large switch includes a plurality of traction points.
• the interlocking system is electrically connected to each traction point.
• the method includes the following steps: S1: collecting general indication information of the large switch and individual indication information of each traction point; S2: based on the collected general indication information and individual indication information of each traction point, determining, by the interlocking system, a position state of the large switch as one of a normal position state, a reverse position state, or a four-open state; and S3: based on the determined position state of the large switch, performing an interlocking function logic operation by the interlocking system.
• This method overcomes the deficiencies in the prior art by adding consistency check between the general indication of the switch and the individual indication information of each traction point, thereby preventing serious accidents such as train derailment, rollover, and sideswipe, and improving the convenience and efficiency of fault diagnosis for the large switch.
• this method is to check the general indication and the individual indication of the switch in the interlocking system. Since all data is sourced from interlocking collection, there is a possibility that both general indication data and individual indication data are collected incorrectly, which affects the accuracy of the final result.
• An objective of the present disclosure is to provide a method for comparing the consistency between a general indication and an individual indication of a switch, a device, and a medium, to overcome the above-mentioned deficiencies in the prior art.
