Description

TECHNICAL FIELD

[0001] The present application relates to the field of rail transit, and in particular to a method, device, equipment, medium and product for judging route unlocking logic of a rail section. BACKGROUND

[0002] Currently, rail circuits are used in domestic stations to monitor whether a rail section is occupied by a locomotive vehicle, to ensure train safety and supervise train operation status. The role of the rail circuit mainly manifests in two aspects: one is to supervise train occupation, and the other is to transmit train information. Rail circuit failure phenomena generally include two kinds: the first is poor section shunting, and the second is rail failure.

[0003] Rail circuit failure will seriously affect the judgment of route unlocking logic of a rail section, and will cause serious deviation when a computer interlocking judges the status of the rail section, thereby affecting train safety. Therefore, how to accurately judge the route unlocking logic of the rail section when the rail circuit fails has become a problem to be solved. SUMMARY

[0004] The present application provides a method, device, equipment, medium and product for judging route unlocking logic of a rail section, to accurately judge the route unlocking logic of the rail section when the rail circuit fails, and to improve train safety.

[0005] According to an aspect of the present application, a method for judging route unlocking logic of a rail section is provided, applied to a computer interlocking, and the method comprises:

[0006] When a rail section route request is monitored, a target rail section is determined, and it is judged whether the target rail section has a rail section failure identifier;

[0007] If yes, a rail section failure type is determined according to the rail section failure identifier;

[0008] If the rail section failure type is poor section shunting, a first section contact state collected by a rail circuit deployed in the target rail section is obtained, and a second section contact state collected by an axle counting circuit deployed in the target rail section is obtained;

[0009] According to the first section contact state and the second section contact state, it is determined whether to perform a route unlocking operation.

[0010] According to another aspect of the present application, a device for judging route unlocking logic of a rail section is provided, configured in a computer interlocking, and the device comprises:

[0011] The fault diagnosis module is used to determine the target track segment and whether the target track segment has a track segment fault indicator when a track segment route request is detected.

[0012] The fault type determination module is used to determine the fault type of the track section based on the track section fault identifier if the target track section has a track section fault identifier.

[0013] The first state acquisition module is used to acquire the first section contact state collected by the track circuit deployed in the target track section and the second section contact state collected by the axle counting circuit deployed in the target track section if the fault type of the track section is section shunt failure.

[0014] The first route unlocking judgment module is used to determine whether to perform a route unlocking operation based on the status of the first segment contact and the status of the second segment contact.

[0015] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0016] At least one processor; and

[0017] A memory communicatively connected to the at least one processor; wherein,

[0018] The memory stores a computer program that can be executed by the at least one processor, which is then executed by the at least one processor to enable the at least one processor to perform the track segment route unlocking logic judgment method according to any embodiment of the present invention.

[0019] According to another aspect of the present invention, a computer-readable storage medium is provided, the computer-readable storage medium storing computer instructions, the computer instructions being configured to cause a processor to execute and implement the path unlocking logic judgment method for a track segment as described in any embodiment of the present invention.

[0020] According to another aspect of the present invention, a computer program product is provided, comprising a computer program that, when executed by a processor, implements the path unlocking logic judgment method for track sections as described in any embodiment of the present invention.

[0021] The technical solution of this invention, upon detecting a track section route request, identifies the target track section and determines whether a track section fault indicator exists within it. If so, the fault type is determined based on the fault indicator. If the fault type is a faulty section routing, the first section contact status acquired by the track circuit deployed in the target track section and the second section contact status acquired by the axle counting circuit deployed in the target track section are obtained. Based on the first and second section contact statuses, it is determined whether to perform a route unlocking operation. This technical solution, by considering different types of track section faults and using a fusion of the section contact status acquired by the track circuit and the section contact status acquired by the axle counting circuit to determine whether to perform a route unlocking operation under corresponding track section faults, achieves accurate judgment of the track section route unlocking logic in the event of a track circuit fault, thus improving train operation safety.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0037] Example 1

[0038] Figure 1This is a flowchart of a method for determining the route unlocking logic of a track section according to Embodiment 1 of the present invention. This embodiment is applicable to situations requiring accurate determination of the route unlocking logic of a track section in the event of a track circuit fault. This method can be executed by a track section route unlocking logic determination device, which can be implemented in hardware and / or software. This track section route unlocking logic determination device can be configured in an electronic device; specifically, it can be configured in a computer-based interlocking (CBI) system. Figure 1 As shown, the method includes:

[0039] S110. When a track section route request is detected, the target track section is identified, and it is determined whether there is a track section fault indicator in the target track section.

[0040] S120. If so, determine the fault type of the track section based on the track section fault identifier.

[0041] S130. If the fault type of the track section is a faulty section circuit, then obtain the first section contact status collected by the track circuit deployed in the target track section, and obtain the second section contact status collected by the axle counting circuit deployed in the target track section.

[0042] S140. Based on the status of the first segment contact and the status of the second segment contact, determine whether to perform a route unlocking operation.

[0043] It should be noted that, due to the limitations imposed by the terrain and the characteristics of the track circuits, common track section fault types include: poor section shunting and track faults.

[0044] Regarding poor circuit shunting in certain sections: This is mainly due to poor conductivity in certain parts of the track circuit, causing the circuit to fail to shunt correctly. This may be caused by rail surface contamination, excessive rail gaps, or damaged insulation materials. In these cases, even if a train occupies the track, the track circuit may fail to detect its presence, leading to misjudgments by the signaling system. Specific examples of the fault are illustrated below:

[0045] When a section of track is faulty, the track circuit relay GJ fails to deactivate and remains energized, resulting in two possible fault phenomena: 1) When a train is in track section IAG, the track circuit cannot detect train occupancy. Because GJ is energized, the computer interlocking system (CBI) cannot display the train occupancy correctly, thus incorrectly processing routes via IAG. 2) If... Figure 2The diagram shows a track section route for a train occupancy route from XL1 to IG, with the signal open. Trains proceed sequentially from CL1G. IAG (Incoming Track Gauge) can only unlock if three checks are met: the previous section is occupied when the current section is occupied; the current section is occupied when the next section is occupied; and the previous section is cleared and the next section is still occupied when the current section is cleared. If a train enters the IAG and a section misalignment occurs, the GJ (Gateway Control Unit) remains active. At this point, the IAG cannot display the red light indicating train occupancy, and the route cannot unlock properly after the train has moved through the IAG.

[0046] Track faults refer to abnormal current flow in the track circuit, usually caused by poor insulation between the track and the ground or between the track and other conductors. This type of fault leads to unstable operation of the track circuit and, in severe cases, may cause signal system failure. Symptoms include a red light band appearing when no vehicle is in use, or a red light band appearing on the track circuit after rain when no vehicle is in use. Specific examples of these faults are as follows:

[0047] When the track malfunctions, the track circuit relay GJ fails to drop and remains in the energized state. Two fault phenomena are described below: (See example...) Figure 2 The diagram shows a track section route. 1) When IAG is not occupied, the track circuit feedback to the computer interlocking system indicates that GJ has dropped, and the interlocking system determines that the section is occupied, making it impossible to process a route through IAG. 2) When processing a receiving route from XL1 to IG, the signal is opened. After the signal is opened, a red light appears for IAG faults, and the receiving route XL1 signal is closed due to a fault.

[0048] In this invention, to address the problems of poor track section routing and track faults, a method of superimposing track circuit axle counting is used to achieve a fusion judgment of the track section status. A pair of axle counting heads is installed in each direction of entry and exit for any track section, and the axle counting circuit, i.e., the axle counting track relay, collects the segment contact status of the track section. A track circuit is set up for any track section, and the track circuit collects the segment contact status of the track section. For example... Figure 3 The diagram shows a data acquisition principle that uses a shaft counting circuit and a track circuit to collect the contact status of a section.

[0049] The axle counter JGJ and track circuit GGJ collect data from their front and rear contacts. CJ-1 and CJ-3 are the front contacts, and CJ-2 and CJ-4 are the rear contacts. When JGJ or GGJ is lifted, the front contacts are energized (1), CJ-1 and CJ-3 are 1, and CJ-2 and CJ-4 are 0. When JGJ or GGJ falls, the rear contacts are energized (1), CJ-1 and CJ-3 are 0, and CJ-2 and CJ-4 are 1. When the section collection status is 10, the section is idle; when the collection status is 01, the section is occupied; and when the collection status is 00 or 11, it is an illegal state.

[0050] Each section is equipped with a "Section Circuit Malfunction" button and a "Track Fault" button, respectively, based on the fault type. Operators select the appropriate button based on the fault type in the track circuit. When the "Section Circuit Malfunction" button is pressed, the computer interlocking system sets the interlocking logic section flag (track section fault indicator) to FLAG1. When the "Track Fault" button is pressed, the computer interlocking system sets the interlocking logic section flag (track section fault indicator) to FLAG2.

[0051] When the computer interlocking system detects a track section route request, it identifies the target track section. The track section route request is a request to establish a receiving route for the track section. The target track section is the track section the train requests to enter. It then determines whether a track section fault indicator (FLAG1 and / or FLAG2) exists for the target track section at the current time. If so, the fault type is determined based on the fault indicator. If the fault indicator is FLAG1, the fault type is a faulty section routing; if the fault indicator is FLAG2, the fault type is a track fault.

[0052] If the track section fault type is a section shunt failure, the system acquires the first section contact status obtained from the track circuit deployed in the target track section, and the second section contact status obtained from the axle counting circuit deployed in the target track section. Based on the first and second section contact statuses, it determines whether to perform a route unlocking operation. This invention considers a state fusion method, combining the section contact status acquired by the track circuit and the section contact status acquired by the axle counting circuit, to determine whether to perform a route unlocking operation, thereby improving the accuracy of route unlocking operation judgment in the event of a section shunt failure.

[0053] In one optional embodiment, determining whether to perform a route unlocking operation based on the state of the first segment contact and the state of the second segment contact includes: determining the state of the first interlocking fusion segment based on the state of the first segment contact and the state of the second segment contact; and determining whether to perform a route unlocking operation based on the state of the first interlocking fusion segment.

[0054] Specifically, based on the contact status of the first and second segments, and using a pre-built interlocking fusion judgment logic table corresponding to segment branching faults, the status of the first interlocking fusion segment is determined. The interlocking fusion judgment logic table corresponding to segment branching faults is shown in Table 1.

[0055] Table 1

[0056]

[0057] By looking up the obtained first and second segment contact states in a table, the interlocked fusion segment state can be obtained, and the final state, i.e., the first interlocked fusion segment state, can be obtained.

[0058] For example, if the first section contact status collected by the track circuit is the lifting state, i.e. "01", and the second section contact status collected by the axle counting circuit is the falling state, i.e. "10", then the corresponding serial number 7 in Table 1 above can be used to determine that the first interlocking fusion section status is occupied.

[0059] Based on the status of the first interlocking fusion section, determine whether to perform a route unlocking operation. Optionally, determining whether to perform a route unlocking operation based on the status of the first interlocking fusion section includes: if the first interlocking fusion section is in an occupied state, then perform a route unlocking operation.

[0060] If the first interlocking fusion section is in an occupied state, route unlocking can be performed according to the "three-point check." The three-point check is: a section is occupied and cleared; the current section is occupied and cleared; and the next section is occupied. If any of these conditions are not met, the section cannot be unlocked. That is, it must be verified that the train (or trainset) indeed came from the previous section (point 1), occupied and cleared (point 2), and entered the next section (point 3); otherwise, unlocking will not be possible.

[0061] For scenarios where the fault type in a track section is a track fault, the following are optional implementation methods for determining whether to perform a route unlocking operation:

[0062] Step a11: If the track section fault type is track fault, then obtain the third section contact status collected by the track circuit deployed in the target track section when the train has not traveled to the target track section, and obtain the fourth section contact status collected by the axle counting circuit deployed in the target track section when the train has not traveled to the target track section.

[0063] Step a12: Obtain the fifth section contact status collected by the track circuit deployed in the target track section when the train travels to the target track section, and obtain the sixth section contact status collected by the axle counting circuit deployed in the target track section when the train travels to the target track section.

[0064] Step a13: Obtain the seventh section contact status collected by the track circuit deployed in the target track section when the train leaves the target track section, and obtain the eighth section contact status collected by the axle counting circuit deployed in the target track section when the train leaves the target track section.

[0065] Step a2: Based on the contact status of the third, fourth, fifth, sixth, seventh, and eighth segments, determine whether to perform a route unlocking operation.

[0066] Optionally, based on the contact states of the third, fourth, fifth, sixth, seventh, and eighth sections, it is determined whether to perform a route unlocking operation, including: determining the state of the second interlocking fusion section based on the contact states of the third and fourth sections; determining the state of the third interlocking fusion section based on the contact states of the fifth and sixth sections; determining the state of the fourth interlocking fusion section based on the contact states of the seventh and eighth sections; and determining whether to perform a route unlocking operation based on the states of the second, third, and fourth interlocking fusion sections.

[0067] Specifically, based on the contact status of the third and fourth sections, and using a pre-built interlocking fusion judgment logic table corresponding to track faults, the status of the second interlocking fusion section is determined. The interlocking fusion judgment logic table corresponding to track faults is shown in Table 2.

[0068] Table 2

[0069]

[0070] Before the train reaches the target track section, the third section contact status is collected by the track circuit deployed in the target track section, and the fourth section contact status is collected by the axle counting circuit deployed in the target track section. If the third section contact status collected by the track circuit is in the lowered state, i.e., "01", and the fourth section contact status collected by the axle counting circuit is in the raised state, i.e., "10", then corresponding to serial number 10 in Table 2, referring to Table 2, we can find that the second interlocking fusion section status is in the idle state.

[0071] When the train reaches the target track section, the fifth section contact status is collected by the track circuit deployed in the target track section, and the sixth section contact status is collected by the axle counting circuit deployed in the target track section. If the fifth section contact status collected by the track circuit is in a fallen state, i.e., "01", and the sixth section contact status collected by the axle counting circuit is also in a fallen state, i.e., "01", then corresponding to serial number 6 in Table 2, referring to Table 2, we can find that the third interlocking fusion section status is in an occupied state.

[0072] When the train leaves the target track section, the status of the seventh section contact is collected by the track circuit deployed in the target track section, and the status of the eighth section contact is collected by the axle counting circuit deployed in the target track section. If the seventh section contact status collected by the track circuit is in the down state, i.e., "01", and the eighth section contact status collected by the axle counting circuit is in the intake state, i.e., "10", then corresponding to serial number 10 in Table 2, referring to Table 2, we can find that the status of the third interlocking fusion section is in the idle state.

[0073] Optionally, based on the status of the second interlocking fusion section, the third interlocking fusion section, and the fourth interlocking fusion section, it is determined whether to perform a route unlocking operation, including: if the second interlocking fusion section is in an idle state, the third interlocking fusion section is in an occupied state, and the fourth interlocking fusion section is in an idle state, then a route unlocking operation is performed.

[0074] Optionally, when both faults exist in the target track section—namely, a faulty section circuit and a track fault—two types of buttons are set according to the track section. These two buttons are mutually exclusive and cannot be pressed simultaneously. Pressing the corresponding button will execute the corresponding logic described above.

[0075] The technical solution of this invention, upon detecting a track section route request, identifies the target track section and determines whether a track section fault indicator exists within it. If so, the fault type is determined based on the fault indicator. If the fault type is a faulty section routing, the first section contact status acquired by the track circuit deployed in the target track section and the second section contact status acquired by the axle counting circuit deployed in the target track section are obtained. Based on the first and second section contact statuses, it is determined whether to perform a route unlocking operation. This technical solution, by considering different types of track section faults and using a fusion of the section contact status acquired by the track circuit and the section contact status acquired by the axle counting circuit to determine whether to perform a route unlocking operation under corresponding track section faults, achieves accurate judgment of the track section route unlocking logic in the event of a track circuit fault, thus improving train operation safety.

[0076] Example 2

[0077] This embodiment, based on the above embodiments, provides a preferred example. Existing technical solutions for resolving track circuit faults require significant manual intervention and regular inspections and maintenance, impacting station route processing efficiency and train throughput. Furthermore, track circuit faults can cause deviations in the computer interlocking's judgment of section status, affecting train operation safety. This invention proposes a method for using axle counters overlaid with track circuits in this scenario. It employs a computer interlocking logic processing method to switch between axle counters and track circuits. Compared to existing solutions, this method solves the problems of faulty circuit routing and track faults, reduces manual maintenance costs, improves track circuit reliability, and increases the efficiency of station route processing.

[0078] To address issues such as faulty track circuit shunts and track malfunctions, a method of superimposing track circuit axle counters is proposed, along with the implementation of interlocking logic and methods by setting relevant buttons.

[0079] 1) Install a pair of axle counting heads in each direction of entry and exit for each section. The section collected by the axle counting track relay JGJ. See the data acquisition principle diagram. Figure 3 .

[0080] 2) A track circuit is set up for each section, and the section data collected by the track circuit is the track relay GGJ. See the data acquisition schematic diagram. Figure 3 .

[0081] 3) The axle counting GJ and track circuit GJ collect data from their front and rear contacts. CJ-1 and CJ-3 are the front contacts, and CJ-2 and CJ-4 are the rear contacts. When the GJ is lifted, the front contacts are energized (1), CJ-1 and CJ-3 are energized (1), and CJ-2 and CJ-4 are energized (0). When the GJ is lowered, the rear contacts are energized (1), CJ-1 and CJ-3 are energized (0), and CJ-2 and CJ-4 are energized (1). When the section collection status is 10, the section is idle; when the collection status is 01, the section is occupied; when the collection status is 00 or 11, it is an illegal state.

[0082] 4) Each section is equipped with a "Bad Circuit" button and a "Track Fault" button according to the fault type. The operator selects the appropriate button based on the fault type of the track circuit. When the "Bad Circuit" button is pressed, the interlocking logic section flag is set to FLAG1. When the "Track Fault" button is pressed, the interlocking logic section flag is set to FLAG2.

[0083] The specific logic for resolving the fault symptoms is explained below:

[0084] I. Poor road segmentation:

[0085] When a faulty circuit breaker occurs in a track section, the station operator presses the "Faulty Circuit breaker" button and sets the faulty section flag to FLAG1. When the section flag is FLAG1, the interlocking judgment logic is shown in Table 1. In the table, "10" indicates that the GJ is lifted; "01" indicates that the GJ is lowered; and "00 / 11" represents an illegal state.

[0086] An example station will be used to illustrate:

[0087] 1) such as Figure 4 The diagram shows a track section route. The route for receiving train XL1 to IG is being processed; signal access is open.

[0088] 2) such as Figure 5 The diagram shows a track section route. When a faulty section branch occurs in the IAG, the station operator presses the "Faulty Branch" button, and the computer interlocking sets the IAG section fault flag to FLAG1.

[0089] 3) Trains proceed sequentially from CL1G. After the train passes IAG, the track circuit collects GGJ data in the lifted state, while the axle counter collects JGJ data in the lowered state. According to number 7 in the table above, the computer interlocking system processes the merged IAG data into an occupied state.

[0090] 4) At this point, based on the three-point check, the route from XL1 to IG can be unlocked normally. The route from XL1 to IG can be found in [link to XL1 route]. Figure 6 The diagram shows the route for the track section.

[0091] II. Track Fault:

[0092] When a track section malfunctions, and the GGJ indicator displays a red light, the station operator presses the "Track Fault" button to set the faulty section marker to FLAG2. When the section marker is FLAG2, the interlocking logic is as shown in Table 2 below. Here, "10" indicates lifting; "01" indicates lowering; and "00 / 11" represents an illegal state.

[0093] An example station will be used to illustrate:

[0094] 1) such as Figure 7 The diagram shows a track section route. A red light indicates a fault in section IAG, and the track circuit data shows section status GGJ as "fallen," making it impossible to arrange a receiving route from XL1 to IG.

[0095] 2) such as Figure 8The diagram shows a track section route. The station operator presses the "Track Fault" button, and the computer interlocking sets the IAG section fault flag to FLAG2. At this time, the track circuit collects data on section GGJ in the dropped state, while the axle counter collects data on section JGJ in the raised state. According to serial number 10 in the table above, the computer interlocking determines that the IAG section is in the raised state, and the XL1 to IG receiving route can be processed.

[0096] 3) Starting from CL1G, when the train reaches IAG, the JGJ collected by the axle counter is in the dropped state, and the GGJ collected by the track circuit is also in the dropped state. According to serial number 6 in the table above, the computer interlocking will process the fused IAG state as the dropped state.

[0097] 4) When the train clears the IAG, the track circuit collects the section status GGJ as the lowered state, but the axle counter collects the JGJ as the raised state. According to serial number 10 in the table above, the computer interlocking will process the IAG as the raised state, and the route can be unlocked normally. The route from XL1 to IG can be found in [reference needed]. Figure 9 The diagram shows the route for the track section.

[0098] 3. When two types of faults exist in a section, two types of buttons are set according to the section. The two buttons are mutually exclusive and cannot be pressed simultaneously. Pressing the corresponding button will execute the corresponding logic described above.

[0099] Computer-based interlocking systems fuse the JGJ (Junction Check and Junction Check) status feedback from axle counters and the GGJ status feedback from track circuits using different section markers, and then use the fused section status for logical processing. This improves the stability and reliability of the interlocking system. This invention proposes a method for using axle counters overlaid with track circuits in this scenario, implementing a logical processing method for switching between axle counters and track circuits through computer-based interlocking. Compared to existing solutions, this method solves the problems of faulty circuit switching and track malfunctions, reduces manual maintenance costs, improves the reliability of track circuits, and increases the efficiency of station route management.

[0100] Example 3

[0101] Figure 10 This is a schematic diagram of a track section route unlocking logic judgment device provided in Embodiment 3 of the present invention. The track section route unlocking logic judgment device provided in this embodiment of the present invention is applicable to situations requiring accurate judgment of track section route unlocking logic in the event of a track circuit fault. This track section route unlocking logic judgment device can be implemented in hardware and / or software, such as... Figure 10 As shown, the device can be configured in a computer-interlocked CBI system and specifically includes: a fault judgment module 201, a fault type determination module 202, a first status acquisition module 203, and a first route unlocking judgment module 204. Among them,

[0102] The fault judgment module 201 is used to determine the target track section and determine whether the target track section has a track section fault identifier when a track section route request is detected.

[0103] The fault type determination module 202 is used to determine the fault type of the track section based on the track section fault identifier if the target track section has a track section fault identifier;

[0104] The first state acquisition module 203 is used to acquire the first section contact state collected by the track circuit deployed in the target track section and the second section contact state collected by the axle counting circuit deployed in the target track section if the fault type of the track section is section shunt failure.

[0105] The first route unlocking judgment module 204 is used to determine whether to perform a route unlocking operation based on the status of the first segment contact and the status of the second segment contact.

[0106] The technical solution of this invention, upon detecting a track section route request, identifies the target track section and determines whether a track section fault indicator exists within it. If so, the fault type is determined based on the fault indicator. If the fault type is a faulty section routing, the first section contact status acquired by the track circuit deployed in the target track section and the second section contact status acquired by the axle counting circuit deployed in the target track section are obtained. Based on the first and second section contact statuses, it is determined whether to perform a route unlocking operation.
