Description

TECHNICAL FIELD

[0001] 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.BACKGROUND

[0002] 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. During train operation, 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.

[0003] 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.

[0004] 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.

[0005] However, 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.SUMMARY

[0006] 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. An interlocking system is used to collect the general indication of the switch, and a monitoring system is used to collect an individual indication of each switch machine, thereby reducing the possibility that the data is collected incorrectly. By comparing the consistency of switch positions collected by a plurality of systems in real time, the accuracy of switch position determination is effectively improved.

[0014] As a preferred technical solution, in the step S5, when the result of analyzing the consistency between the general indication and the individual indication of the switch per second stored in the circular queue is continuously inconsistent within the preset time interval, a fault alarm prompt is generated; and when the result of analyzing the consistency between the general indication and the individual indication of the switch per second stored in the circular queue is continuously consistent within the preset time interval, a fault alarm that has occurred is restored.

Apparently, the described embodiments are merely some rather than all of the embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present disclosure.

[0024] As shown in FIG. 1, the present disclosure provides a method for comparing the consistency between a general indication and an individual indication of a switch, including the following steps.

[0025] In S1, switch machine devices are grouped according to device information and collected information of all switch machines in a station yard. In this embodiment, the switch machines with an interlocking relationship are divided into a group according to switch machine types, naming rules, and association relationships.

[0026] In S2, collected data related to the general indication and the individual indication of the switch is acquired in real time, where the collected data includes a general indication state of the switch collected by an interlocking system, an individual indication state of each switch machine collected by a monitoring system, and a rotation state of each switch machine.

[0027] In S3, the consistency between the general indication and the individual indication of the switch is analyzed once per second according to the real-time collected data.

[0028] In a preferred embodiment, as shown in FIG. 2, the result of analyzing the consistency between the general indication and the individual indication of the switch per second includes an invalid case, an inconsistent case, and a consistent case.(1) Invalid case

[0029] The result of analyzing the consistency between the general indication and the individual indication of the switch per second is invalid when any one of the following conditions is met: 1, any switch machine is in a rotation state; 2, the general indication of the switch is a fault position; and 3, the general indication of the switch is a loss of indication, and individual indications of the switch machines are not all normal positions or not all reverse positions. (2) Inconsistent case

[0030] The inconsistent case in the result of analyzing the consistency between the general indication and the individual indication of the switch per second includes general indication and normal position inconsistency, general indication and reverse position inconsistency, and general indication and loss-of-indication inconsistency: 1, when the general indication is a normal position and at least one individual indication is not a normal position, the per-second analysis result is the general indication and normal position inconsistency; 2, when the general indication is a reverse position and at least one individual indication is not a reverse position, the per-second analysis result is the general indication and reverse position inconsistency; and 3, when the general indication is a loss of indication and individual indications are all normal positions or all reverse positions, the per-second analysis result is the general indication and loss-of-indication inconsistency. (3) Consistent case

[0031] The consistent case in the result of analyzing the consistency between the general indication and the individual indication of the switch per second includes general indication and normal position consistency and general indication and reverse position consistency: 1, when the general indication is a normal position and individual indications are all normal positions, the per-second analysis result is the general indication and normal position consistency; and 2, when the general indication is a reverse position and individual indications are all reverse positions, the per-second analysis result is the general indication and reverse position consistency.

[0032] In S4, a result of analyzing the consistency between the general indication and the individual indication of the switch per second is stored into a circular queue, and the circular queue is updated in real time such that the circular queue only retains a latest analysis result within 10 s.

[0033] In S5, when a total duration of the per-second analysis result stored in the circular queue reaches 10 s, namely, when the circular queue is full with 10 pieces of data, continuous analysis on the consistency between the general indication and the individual indication of the switch is performed in real time according to the per-second analysis result currently stored in the circular queue.

[0034] When the result of analyzing the consistency between the general indication and the individual indication of the switch per second stored in the circular queue is inconsistent for 10 consecutive seconds, a fault alarm prompt is generated; and when the result of analyzing the consistency between the general indication and the individual indication of the switch per second stored in the circular queue is consistent for 10 consecutive seconds, a fault alarm that has occurred is restored. The occurrence and restoration of faults at different switch positions are independent of each other.

[0035] In a preferred embodiment, as shown in FIG. 3, a result of continuous analysis on the consistency between the general indication and the individual indication of the switch includes general indication and normal position inconsistency, general indication and reverse position inconsistency, and general indication and loss-of-indication inconsistency according to different inconsistency cases:(1) General indication and normal position inconsistency

[0036] Occurrence: when the result of analyzing the consistency between the general indication and the individual indication of the switch per second is continuously the general indication and normal position inconsistency within 10 s, a fault alarm prompt is generated, and the continuous analysis result is that the general indication and normal position inconsistency occurs.

[0037] Restoration: after the fault of general indication and normal position inconsistency occurs, when the result of analyzing the consistency between the general indication and the individual indication of the switch per second is continuously the general indication and normal position consistency within 10 s, a fault alarm that has occurred is restored, and the continuous analysis result is that the general indication and normal position inconsistency is restored.(2) General indication and reverse position inconsistency

[0038] Occurrence: when the result of analyzing the consistency between the general indication and the individual indication of the switch per second is continuously the general indication and reverse position inconsistency within 10 s, a fault alarm prompt is generated, and the continuous analysis result is that the general indication and reverse position inconsistency occurs.

[0039] Restoration: after the fault of general indication and reverse position inconsistency occurs, when the result of analyzing the consistency between the general indication and the individual indication of the switch per second is continuously the general indication and reverse position consistency within 10 s, a fault alarm that has occurred is restored, and the continuous analysis result is that the general indication and reverse position inconsistency is restored.(3) General indication and loss-of-indication inconsistency

[0040] Occurrence: when the result of analyzing the consistency between the general indication and the individual indication of the switch per second is continuously the general indication and loss-of-indication inconsistency within 10 s, a fault alarm prompt is generated, and the continuous analysis result is that the general indication and loss-of-indication inconsistency occurs.

[0041] Restoration: after the fault of general indication and loss-of-indication inconsistency occurs, when the result of analyzing the consistency between the general indication and the individual indication of the switch per second is continuously the general indication and normal position consistency or the general indication and reverse position consistency within 10 s, a fault alarm that has occurred is restored, and the continuous analysis result is that the general indication and loss-of-indication inconsistency is restored.
