[0002] Turnouts are an important part of track lines. Their main function is to connect and switch tracks in different directions, thereby realizing vehicle scheduling and steering. By setting turnouts reasonably, transportation efficiency can be improved, ensuring that trains run according to the scheduled routes, and improving the safety performance of trains. The positions of turnouts include several states, such as positioning and reverse position. Positioning refers to the turnout being in a straight line, and reverse position refers to the turnout being in a siding state. During the operation of the train, due to the above-mentioned characteristics of the turnout, it is easy for trains in the lateral area to scrape against trains in the forward area, thus causing safety problems.

[0003] At present, the section protection table is often pre-configured for the sections where scratches may occur, and the lateral area of ​​the turnout is protected during train operation based on the configuration information in the section protection table. However, this method can only guarantee the safety protection of the turnouts that are configured with data, and cannot achieve safety protection for the turnouts that are not configured with data, resulting in insufficient dynamic flexibility and high maintenance costs. Summary of the invention In view of this, an embodiment of this specification provides a train safety protection method.

Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0015] In addition, it should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in one or more embodiments of this specification are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0016] First, the terms involved in one or more embodiments of this specification are explained.

[0017] LC (Line Controller): The LC system is mainly responsible for calculating the movement authorization (MA) for the communication trains within its control range based on the position information reported by the communication trains and the route arranged by the interlocking and the track occupancy / free information provided by the trackside equipment, so as to ensure the safe operation of the communication trains within its control area. It should be noted that in one or more embodiments of this specification, the method applied to LC can also be applied to ZC (Zone Controller).

[0018] CI (Computer Interlocking): CI system is a station interlocking device that uses computers to perform logical operations on the operating commands of station operators and the information displayed on site, thereby realizing centralized control of signals and switches, etc., so that they can achieve mutual restraint, that is, microcomputer centralized interlocking.

[0019] MA (Movement Authority): Used to provide permission for trains running in a specific direction to enter or pass through a certain track section ahead.

[0020] Axle counter: A technical device used to calculate the number of axles of vehicles entering and exiting a section, and to analyze whether there are any vehicles occupying the section.

[0021] Axle counter section: Also referred to as AC in this manual, it refers to a section of track on a railway line that is monitored by an axle counter. This section is usually defined by two axle counters, one at the beginning (entrance) of the section and the other at the end (exit) of the section. The two axle counters together form an axle counter section.

[0022] Physical section: It is a closed section composed of multiple axle counters. If it does not contain a turnout, one axle counter section is one physical section; if it contains a turnout, one physical section may contain multiple axle counter sections. It should be noted that the occupancy status reported by the CI system to the LC system is in units of physical sections.

[0023] Turnout position: including three states: fixed position, reverse position and four-way position. Fixed position means that the turnout is in a straight line state, reverse position means that the turnout is in a side line state, and four-way position is a fault state.

[0024] Warning sign: A sign used to indicate that when a train stops, it is not allowed to cross the switch direction or the intersection direction to prevent the train stopped on the line from having a side collision with the train on the adjacent line.

[0025] Limit violation: It means that a train collides with a train coming from the other side within the warning mark of the switch.

[0026] In this specification, a train safety protection method is provided. This specification also involves a train safety protection device, a computing device, a computer-readable storage medium, and a computer program product, which are described in detail one by one in the following embodiments.

[0027] See also Figure 1 , Figure 1 A flow chart of a train safety protection method provided according to an embodiment of the present specification is shown, which specifically includes the following steps.

[0028] Step 102: Determine the movement authorization of the train to be tested, and based on the movement authorization, determine the physical section to be tested corresponding to the train to be tested, wherein the physical section to be tested includes a target axle counting section, and the target axle counting section includes a target turnout.

[0029] In practical applications, the movement authorization of the train to be tested can be determined, and based on the movement authorization, the physical section to be tested corresponding to the train to be tested can be determined, so that subsequent judgment on the side protection of the switch can be made according to the occupancy status of the physical section to be tested.

[0030] One or more embodiments of the present specification may be applied to LC or ZC, and LC or ZC may perform switch side protection on the axle counting section where switches exist during train operation, thereby achieving safety protection for the train.

[0031] Specifically, a turnout is an important part of a track line, and its main function is to connect and switch tracks in different directions, thereby realizing the dispatching and turning of vehicles. The turnout position can include the fixed position and the reverse position, wherein the fixed position refers to the turnout being in a straight line state, and the reverse position refers to the turnout being in a side line state.

[0032] In actual applications, since there is a risk of collision between trains in the lateral area and trains in the forward area near the turnout, when constructing the track, warning signs are often set between the two merging lines, and axle intrusion counters are set in areas where scratches are likely to occur. The positions of the axle intrusion counters are recorded and maintained in the electronic map accordingly.

[0033] Optionally, the vertical distance between the warning mark and the two converging lines can be set to be the same, for example, 2 m, which can be set specifically according to the requirements in actual applications.

[0034] Optionally, the axle intrusion counter can be arranged on the turnout section and on the inner side of the warning mark.

[0035] In actual application, in order to ensure safety, when a train stops near a turnout, it should stop outside the warning mark. When a train runs into the inner side of the intrusion limit axle counter, or stops inside the intrusion limit axle counter, it may intrude into the adjacent line limit, affecting driving safety.

[0036] See also Figure 2 , Figure 2 FIG. 1 is a schematic diagram showing a limit violation during train operation provided by an embodiment of the present specification. Figure 2 As shown in (a) in the figure, when a train in the lateral area enters the inner side of the warning mark, it is very likely to collide with a train in the forward area, thus causing a limit violation. Figure 2As shown in (b), the vertical distance between the warning mark and the forward section and the lateral section is 2 meters, and the axle counter is set on the lateral section and is located inside the warning mark. If a train in the lateral area stops inside the axle counter or runs inside the axle counter, it is very likely to scrape against a train in the forward section, resulting in a limit violation.

[0037] In actual application, in order to avoid limit intrusion and safety problems, it is necessary to protect the lateral area of ​​the turnout, that is, turnout side protection is required. At present, the common method is to configure protection data in the section that needs to be protected, maintain a section protection table, and implement turnout side protection based on the section protection table. However, this method can only protect the turnout section with protection data configured, and cannot protect the turnout section without configuration data, which makes the turnout side protection not flexible enough and the system maintenance cost is high.

[0038] Based on this, an embodiment of the present specification provides a train safety protection method, which determines the movement authorization of the train to be tested, and based on the movement authorization, determines the physical section to be tested corresponding to the train to be tested, wherein the physical section to be tested includes a target axle counting section, and the target axle counting section includes a target turnout; when the occupancy status of the physical section to be tested is occupied, a turnout position check is performed on the target axle counting section according to the current turnout position of the target turnout, and when the target axle counting section meets the turnout position check, an intrusion detection is performed on the target axle counting section to obtain a first detection result; based on the first detection result, safety protection processing is performed on the train to be tested.

[0039] In this way, by determining the physical section to be tested corresponding to the train to be tested based on mobile authorization, the target axle counting section can be detected for limit intrusion based on the occupancy status of the physical section to be tested, thereby improving detection efficiency and accuracy; by performing a switch position check on the target axle counting section according to the current switch position of the target switch when the occupancy status of the physical section to be tested is occupied, and performing limit intrusion detection on the target axle counting section when the target axle counting section meets the switch position check, limit intrusion detection can be achieved based on information such as the switch position, physical section occupancy status, and axle counting section occupancy status during train operation, without relying on configuration tables or pre-configuration of protection data, thereby reducing maintenance costs, improving system flexibility, and realizing real-time protection during train operation, realizing switch side protection, and ensuring train driving safety.

[0040] According to an optional embodiment of the present specification, the movement authorization of the train to be tested may be determined, and based on the movement authorization, the physical section to be tested corresponding to the train to be tested may be determined.

[0041] Specifically, the train to be tested can be understood as a train that is currently undergoing turnout side defense detection. The physical section to be tested can be understood as a physical section that includes a target turnout. The target turnout can be understood as a turnout included in a target axle counting section. The physical section to be tested includes a target axle counting section and an associated axle counting section that is associated with the target axle counting section. The target axle counting section and the associated axle counting section both include a target turnout, and the target axle counting section and the associated axle counting section share a portion of the same track.

[0042] Optionally, the movement authorization is calculated for the train to be tested based on the route handled by LC or ZC based on interlocking.

[0043] According to another optional embodiment of the present specification, the movement authorization may be determined based on the route handled by the interlocking for the train to be tested, and the physical section to be tested corresponding to the train to be tested may be determined based on the movement authorization.

[0044] In one or more optional embodiments of the present specification, determining the physical section to be tested corresponding to the train to be tested based on the movement authorization may include the following steps: Determine the rear position of the train to be tested; querying at least one axle counting section from the rear position of the vehicle to the end point of the movement authorization; At least one axle counting section is traversed to obtain a target axle counting section including a turnout, and the physical section to be measured to which the target axle counting section belongs is determined.

[0045] Optionally, the rear position of the train to be tested can be autonomously located by the train's onboard system and sent to the LC.

[0046] In practical applications, when LC obtains the rear position of the train to be tested and calculates the movement authorization, it can query the existing axle counting sections within the distance from the rear position to the end point of the movement authorization to obtain an axle counting section sequence.

[0047] Optionally, the axle counting segment sequence may be denoted as {ACn}, and each axle counting segment in the axle counting segment sequence may be denoted as AC.

[0048] Optionally, the axle counting segments may be queried starting from the rear of the vehicle and moving in a direction farther from the rear of the vehicle until the end of the movement authorization is found, thereby obtaining the axle counting segment sequence {ACn}. Alternatively, the axle counting segments may be queried starting from the end of the movement authorization and moving in a direction closer to the rear of the vehicle until the rear of the vehicle is found, thereby obtaining the axle counting segment sequence {ACn}. In the axle counting segment sequence {ACn}, each AC may be arranged one by one in the order of the query.

[0049] Furthermore, when the axle counting section sequence {ACn} is obtained, each AC in {ACn} can be traversed to obtain the target axle counting section including the turnout.

[0050] Specifically, the target axle counting section is an axle counting section in the axle counting section sequence {ACn}, including the target turnout. The target axle counting section belongs to the physical section to be measured, and the target axle counting section has a corresponding associated axle counting section.

[0051] By applying this embodiment, by determining the rear position of the train to be tested; querying at least one axle counting section between the rear position and the end point of the movement authorization; traversing at least one axle counting section to obtain the target axle counting section containing the turnout, and determining the physical section to be tested to which the target axle counting section belongs, it is possible to detect whether each axle counting section within the moving range of the train to be tested contains a turnout, thereby enabling subsequent turnout side defense judgment to be made for the axle counting section with a turnout, and enabling real-time detection of limit intrusion during train operation.

[0052] Step 104: When the occupancy state of the physical section to be tested is occupied, a turnout position check is performed on the target axle counting section according to the current turnout position of the target turnout, and when the target axle counting section satisfies the turnout position check, an intrusion detection is performed on the target axle counting section to obtain a first detection result.

[0053] In actual applications, when the physical section to be tested is determined based on mobile authorization, the occupancy status of the physical section to be tested can be judged. When the occupancy status of the physical section to be tested is occupied, the target axle counting section is checked for switch position based on the current switch position of the target switch. When the target axle counting section meets the switch position check, the target axle counting section is checked for intrusion to obtain a first detection result.

[0054] Optionally, the occupancy state of the physical segment to be tested may include occupied or idle, and different occupancy states correspond to different subsequent processing logics.

[0055] It should be noted that, since the interlocking reports the occupancy status to the LC, it is often in units of physical sections. Therefore, when the target axle counting section with a switch is determined based on the mobile authorization, it is necessary to determine the physical section to be tested to which the target axle counting section belongs, and determine the occupancy status of the target axle counting section based on the occupancy status of the physical section to be tested and the train position and other information.

[0056] Optionally, the physical section to be measured to which the target axle counting section belongs can be determined according to configuration information in the electronic map.

[0057] Optionally, the occupancy status of the physical segment to be measured may be determined by an axle counter on the physical segment to be measured and reported by the CI to the LC.

[0058] Specifically, the current turnout position of the target turnout can be understood as the actual current position of the target turnout, which can be a positioning position or a reverse position. The limit intrusion detection can be understood as a detection of whether the train to be tested in the target axle counting section will intrude on the limit with other trains. The first detection result can be understood as the detection result obtained by performing the limit intrusion detection when the occupancy state of the physical section to be tested is occupied.

[0059] In one or more optional embodiments of the present specification, performing a turnout position check on a target axle counting section according to the current turnout position of the target turnout may include the following steps: It is determined whether the set turnout position of the target turnout is consistent with the current turnout position. If they are consistent, the target axle counting section meets the turnout position check, wherein the set turnout position is determined according to the planned running direction of the train to be tested.

[0060] Specifically, setting the switch position can be understood as a correct switch position.

[0061] Optionally, the switch position can be set according to the planned running direction of the train to be tested. The switch position is set to be consistent with the planned running direction of the train to be tested. Exemplarily, if the planned running direction of the train to be tested is the main line running, the switch position is set to the fixed position; if the planned running direction of the train to be tested is the side line running, the switch position is set to the reverse position.

[0062] In actual applications, when the occupancy status of the physical section to be tested is occupied, the target axle counting section can be checked for the switch position according to the current switch position of the target switch. If the switch position check is satisfied, the subsequent limit intrusion detection can be further performed. If the switch position check is not satisfied, it means that the train to be tested cannot pass through the target axle counting section normally. Therefore, the limit intrusion detection can be omitted, and other processing logic can be executed for the train to be tested.

[0063] By applying this embodiment, by performing a switch position check on the target axle counting section based on the current switch position of the target switch, it is possible to determine whether the set switch position of the target switch is consistent with the current switch position, thereby being able to determine whether subsequent limit intrusion detection is required for the train to be tested and the target axle counting section, which is beneficial to improving the accuracy of the detection logic.

[0064] Furthermore, in the scenario where the physical section to be tested is occupied, if the set switch position of the target switch is consistent with the current switch position, it is also necessary to determine the execution logic of the subsequent limit intrusion detection based on the cause that caused the physical section to be tested to be occupied.

[0065] Specifically, the reasons for the occupation of the physical section to be tested may include the train to be tested entering the target axle counting section, or other trains (such as communication trains or non-communication trains) entering the associated axle counting section. Different reasons correspond to different detection logics.

[0066] According to an optional embodiment of the present specification, when the target axle counting section meets the switch position inspection, performing limit intrusion detection on the target axle counting section to obtain a first detection result may include the following steps: Detect whether the train to be tested is located in the target axle counting section; If not, determining that the first detection result is the target axle counting section occupation caused by the non-communication vehicle; Based on the first detection result, safety protection processing is performed on the train to be tested, including: The movement authorization is updated based on a preset interval distance, wherein the preset interval distance represents the interval distance between the train to be measured and the target axle counting section.

[0067] Optionally, detecting whether the train to be tested is located in the target axle counting section may include: judging whether the train to be tested is located in the target axle counting section according to the train position reported by the train to be tested.

[0068] In actual applications, in the scenario where the physical section to be measured is occupied, if the set switch position of the target switch is consistent with the current switch position, it can be determined that the occupancy status of the target axle counting section is occupied, and the occupancy status of the associated axle counting section is idle.

[0069] Further, when it is detected that the train to be tested is not located in the target axle counting section, it can be determined that the cause of occupation of the physical section to be tested is occupation of the target axle counting section caused by a non-communication vehicle entering the associated axle counting section. Therefore, the first detection result is occupation of the target axle counting section caused by a non-communication vehicle.

[0070] Accordingly, based on the first detection result, performing safety protection processing on the train to be detected may include: updating the movement authorization based on a preset interval distance.

[0071] Specifically, the preset interval distance represents the interval distance between the train to be tested and the target axle counting section. The preset interval distance can be set according to the requirements in the actual application, for example, it can be set to the distance of an axle counting section.

[0072] In practical applications, when the first detection result is that the target axle counting section is occupied by a non-communication vehicle, the LC can control the distance between the train to be tested and the target axle counting section by one axle counting section by updating the movement authorization, thereby preventing the train to be tested from infringing the limit with other trains.

[0073] Furthermore, when the non-communication vehicle passes through the target axle counting section and restores communication, the interlocking can be notified to process an approach for the train to be tested, and a new movement authorization can be calculated for the train to be tested based on the approach processed by the interlocking.

[0074] By applying this embodiment, by detecting whether the train to be tested is located in the target axle counting section, it is possible to determine that the first detection result is the occupation of the target axle counting section caused by a non-communication vehicle when the train to be tested is not located in the target axle counting section, thereby controlling the train to be tested to maintain a preset interval with the target axle counting section according to the detection result, thereby realizing lateral area protection of the turnout, and further realizing safety protection of the train to be tested.

[0075] According to another optional embodiment of the present specification, the physical section to be tested further includes an associated axle counting section, and the associated axle counting section and the target axle counting section share the same track; and detecting whether the train to be tested is located after the target axle counting section may further include the following steps: If so, check whether there is location information of other trains in the associated axle counting section; In the case where there is location information of other trains, determining that the first detection result is that there are other trains in the associated axle counting section; Based on the first detection result, safety protection processing is performed on the train to be tested, including: Control the train to be tested to perform emergency braking.

[0076] In practical applications, when it is detected that the train to be tested is located in the target axle counting section, it can be determined that the cause of the occupation of the physical section to be tested is that the train to be tested enters the target axle counting section. In this case, protection can be further provided for the associated axle counting section and the intrusion area.

[0077] It should be noted that the train to be tested is located in the target axle counting section, which may be that the front end of the train to be tested enters the target axle counting section, or the entire train to be tested is located in the target axle counting section.

[0078] Optionally, when it is detected that the train to be tested is located in the target axle counting section, it may be detected whether there is location information of other trains in the associated axle counting section.

[0079] Furthermore, the position information of other trains may be sent to the LC by other trains located in the associated axle counting section. The LC may detect whether the position information sent by the train located in the associated axle counting section is received.

[0080] In actual applications, when it is detected that there are other trains in the associated axle counting section, it can be determined that the first detection result is that there are other trains in the associated axle counting section.

[0081] Accordingly, based on the first detection result, performing safety protection processing on the train to be tested may include: controlling the train to be tested to perform emergency braking.

[0082] In the actual implementation process, if the train to be tested is located in the target axle counting section and other trains are detected on the associated axle counting section, the train to be tested and the trains on the associated axle counting section are likely to violate the limit. Therefore, it is necessary to control the train to be tested to perform emergency braking to avoid violation of the limit.

[0083] By applying this embodiment, when it is detected that the train to be tested is located in the target axle counting section, the location information of other trains is detected in the associated axle counting section, so that the associated axle counting section can be protected. When there is a car in the associated axle counting section, the train to be tested can be timely controlled to perform emergency braking, thereby avoiding limit intrusion, realizing side protection of the turnout and ensuring train safety.

[0084] In actual applications, when there are no other trains in the associated axle counting section, it is also necessary to protect the restricted area.

[0085] According to another optional embodiment of the present specification, after detecting whether there is location information of other trains in the associated axle counting section, the following steps may also be included: In the absence of position information of other trains, a turnout type check is performed on the target axle counting section and an axle counter type check is performed on the associated axle counting section; When the target axle counting section satisfies the turnout type check and the associated axle counting section satisfies the axle counter type check, an intrusion detection is performed on an adjacent axle counting section of the associated axle counting section to obtain a first detection result.

[0086] Specifically, the turnout type check may include: determining whether the turnout type of the target turnout is a single-action turnout.

[0087] Optionally, when the turnout includes an associated turnout, the turnout type is a double-action turnout and no limit intrusion detection is performed; when the turnout does not include an associated turnout, the turnout type is a single-action turnout and limit intrusion detection is performed.

[0088] Specifically, the axle counter type check may include: determining whether the axle counter on the other side of the associated axle counter section is an intrusion axle counter.

[0089] Optionally, when the axle counter on the other side is not an intrusion axle counter, the intrusion detection is not performed; when the axle counter on the other side is an intrusion axle counter, the intrusion detection is performed.

[0090] Specifically, the target axle counting section satisfies the turnout type check, which can be understood as the target turnout is a single-action turnout; the associated axle counting section satisfies the axle counter type check, which can be understood as the axle counter on the other side of the associated axle counting section is an intrusion limit axle counter.

[0091] Specifically, the first detection result can be understood as a detection result in a scenario where the physical segment to be tested is occupied.

[0092] It should be noted that the axle counter on the other side of the associated axle counting section is an axle counter that is not located on the common track of the target axle counting section and the associated axle counting section.

[0093] In practical applications, when the target turnout is a single-action turnout and the axle counter on the other side of the associated axle counting section is an intrusion axle counter, an intrusion detection can be performed on the adjacent axle counting section of the associated axle counting section to obtain a first detection result.

[0094] By applying this embodiment, in the absence of position information of other trains, a turnout type check is performed on the target axle counting section and an axle counter type check is performed on the associated axle counting section; when the target axle counting section satisfies the turnout type check and the associated axle counting section satisfies the axle counter type check, an intrusion detection is performed on the adjacent axle counting section of the associated axle counting section to obtain a first detection result, which can eliminate the situation where an intrusion detection is not necessary and realize protection of the intrusion area, thereby realizing side protection of the turnout and ensuring train safety.

[0095] Further, according to an optional embodiment of the present specification, performing limit intrusion detection on adjacent axle counting sections of the associated axle counting section to obtain a first detection result may include the following steps: Determine whether there are switches in adjacent axle counting sections; When there is no turnout in the adjacent axle counting section, or when there is a turnout in the adjacent axle counting section and the turnout position check is satisfied, a first detection result is obtained based on the occupation state of the adjacent axle counting section; Based on the first detection result, safety protection processing is performed on the train to be tested, including: When the first detection result indicates that the adjacent axle counting section is occupied, the train to be tested is controlled to perform emergency braking.

[0096] Specifically, the adjacent axle counting section may be understood as the next axle counting section adjacent to the associated axle counting section.

[0097] Optionally, adjacent axle counting sections satisfying the switch position check may include: in the adjacent axle counting sections, the current switch position of the switch is consistent with the set switch position.

[0098] Specifically, the current switch position can be understood as the actual switch position of the switch; the set switch position can be understood as the switch position required by the adjacent axle counting section, that is, the correct switch position.

[0099] In actual applications, when there is a switch in the adjacent axle counting section but the current switch position is inconsistent with the set switch position, no intrusion detection is performed; when there is no switch in the adjacent axle counting section, or there is a switch in the adjacent axle counting section and the current switch position is consistent with the set switch position, intrusion detection is performed on the intrusion area.

[0100] Furthermore, the first detection result may be obtained based on the occupancy status of adjacent axle counting sections.

[0101] In the actual implementation process, LC can detect whether there are other trains in the adjacent axle counting section. If so, the first detection result is that the adjacent axle counting section is occupied and the intrusion area needs to be protected; if not, the first detection result is that the adjacent axle counting section is idle and the intrusion area does not need to be protected.

[0102] Accordingly, based on the first detection result, performing safety protection processing on the train to be detected may include: When the first detection result indicates that the adjacent axle counting section is occupied, the train to be tested is controlled to perform emergency braking.

[0103] In actual applications, if it is detected that the adjacent axle counting section is occupied, there may be a risk of intrusion in the restricted area. Therefore, it is necessary to control the emergency braking of the train to be tested to avoid collision with the train in the restricted area.

[0104] By applying this embodiment, it is determined whether there is a turnout in the adjacent axle counting section; when there is no turnout in the adjacent axle counting section, or when there is a turnout in the adjacent axle counting section and the turnout position check is satisfied, a first detection result is obtained based on the occupancy status of the adjacent axle counting section; when the first detection result is that the adjacent axle counting section is occupied, emergency braking of the train to be tested is controlled, and when there is no train in the associated axle counting section, the restricted area can be further protected to ensure that the train to be tested will not scratch the train in the restricted area, thereby realizing side protection of the turnout and ensuring train safety.

[0105] Step 106: Based on the first detection result, safety protection processing is performed on the train to be tested.

[0106] In practical applications, when the target axle counting section is subjected to limit intrusion detection and the first detection result is obtained, safety protection processing can be performed on the train to be tested based on the first detection result, thereby realizing side protection of the turnout and avoiding limit intrusion.

[0107] Optionally, based on different application scenarios, the first detection results may include multiple types, and different first detection results may correspond to different safety protection processes. According to the first detection results, corresponding safety protection processes may be performed on the train to be tested.

[0108] According to an optional embodiment of the present specification, the physical section to be tested may further include an associated axle counting section, and the associated axle counting section and the target axle counting section share the same track; after determining the movement authorization of the train to be tested and determining the physical section to be tested corresponding to the train to be tested based on the movement authorization, the following steps may also be included: When the occupation status of the physical section to be tested is idle, a turnout type check is performed on the target axle counting section and an axle counter type check is performed on the associated axle counting section; When the target axle counting section satisfies the turnout type check and the associated axle counting section satisfies the axle counter type check, performing limit intrusion detection on an adjacent axle counting section of the associated axle counting section to obtain a second detection result; Based on the second detection result, safety protection processing is performed on the train to be tested.

[0109] In actual applications, when the physical segment to be tested is idle, the detection logic for protecting the restricted area can be executed.

[0110] Specifically, the turnout type check may include: determining whether the turnout type of the target turnout is a single-action turnout.

[0111] Optionally, when the turnout includes an associated turnout, the turnout type is a double-action turnout and no limit intrusion detection is performed; when the turnout does not include an associated turnout, the turnout type is a single-action turnout and limit intrusion detection is performed.

[0112] Specifically, the axle counter type check may include: determining whether the axle counter on the other side of the associated axle counter section is an intrusion axle counter.

[0113] Optionally, when the axle counter on the other side is not an intrusion axle counter, the intrusion detection is not performed; when the axle counter on the other side is an intrusion axle counter, the intrusion detection is performed.

[0114] Specifically, the target axle counting section satisfies the turnout type check, which can be understood as the target turnout is a single-action turnout; the associated axle counting section satisfies the axle counter type check, which can be understood as the axle counter on the other side of the associated axle counting section is an intrusion limit axle counter.

[0115] It should be noted that the axle counter on the other side of the associated axle counting section is an axle counter that is not located on the common track of the target axle counting section and the associated axle counting section.

[0116] Specifically, the second detection result can be understood as a detection result in a scenario where the physical segment to be tested is idle.

[0117] In actual applications, when the target turnout is a single-motion turnout and the axle counter on the other side of the associated axle counting section is an intrusion axle counter, an intrusion detection can be performed on the adjacent axle counting section of the associated axle counting section to obtain a second detection result in the scenario where the physical section to be tested is idle.

[0118] By applying this embodiment, when the occupancy status of the physical section to be tested is idle, a turnout type check is performed on the target axle counting section and an axle counter type check is performed on the associated axle counting section; when the target axle counting section satisfies the turnout type check and the associated axle counting section satisfies the axle counter type check, an intrusion detection is performed on the adjacent axle counting section of the associated axle counting section. In the scenario where the physical section to be tested is idle, the detection logic for protecting the intrusion area can be executed to obtain a second detection result, thereby realizing turnout side protection and ensuring train safety when the physical section to be tested is idle.

[0119] According to an optional embodiment of the present specification, performing limit intrusion detection on an adjacent axle counting section of the associated axle counting section to obtain a second detection result may include the following steps: Determine whether there are switches in adjacent axle counting sections; When there is no turnout in the adjacent axle counting section, or when there is a turnout in the adjacent axle counting section and the turnout position check is satisfied, a second detection result is obtained based on the occupation state of the adjacent axle counting section; Based on the second detection result, safety protection processing is performed on the train to be tested, including: When the second detection result is that the adjacent axle counting section is occupied, the train to be tested is controlled not to enter the target axle counting section.

[0120] Specifically, the adjacent axle counting section may be understood as the next axle counting section adjacent to the associated axle counting section.

[0121] Optionally, adjacent axle counting sections satisfying the switch position check may include: in the adjacent axle counting sections, the current switch position of the switch is consistent with the set switch position.

[0122] Specifically, the current switch position can be understood as the actual switch position of the switch; the set switch position can be understood as the switch position required by the adjacent axle counting section, that is, the correct switch position.

[0123] In actual applications, when there is a switch in the adjacent axle counting section but the current switch position is inconsistent with the set switch position, no intrusion detection is performed; when there is no switch in the adjacent axle counting section, or there is a switch in the adjacent axle counting section and the current switch position is consistent with the set switch position, intrusion detection is performed on the intrusion area.

[0124] Furthermore, a second detection result may be obtained based on the occupancy status of adjacent axle counting sections.

[0125] In the actual implementation process, LC can detect whether there are other trains in the adjacent axle counting section. If so, the second detection result is that the adjacent axle counting section is occupied and the restricted area needs to be protected; if not, the second detection result is that the adjacent axle counting section is idle and the restricted area does not need to be protected.

[0126] Accordingly, based on the second detection result, performing safety protection processing on the train to be tested may include: When the second detection result is that the adjacent axle counting section is occupied, the train to be tested is controlled not to enter the target axle counting section.

[0127] In actual applications, if it is detected that the adjacent axle counting section is occupied, the restricted area may be at risk of being infringed due to the entry of other trains. Therefore, it is necessary to control the train to be tested not to enter the target axle counting section to avoid collision with trains that may enter the restricted area.

[0128] By applying this embodiment, it is determined whether there is a turnout in the adjacent axle counting section; when there is no turnout in the adjacent axle counting section, or when there is a turnout in the adjacent axle counting section and the turnout position check is satisfied, a second detection result is obtained based on the occupancy status of the adjacent axle counting section; when the second detection result is that the adjacent axle counting section is occupied, the train to be tested is controlled not to enter the target axle counting section, and when the physical section to be tested is idle, the restricted area can be further protected to ensure that the train to be tested will not scratch against a train that may enter the restricted area, thereby achieving side protection of the turnout and ensuring train safety.

[0129] An embodiment of the present specification provides a train safety protection method, which determines the movement authorization of a train to be tested, and based on the movement authorization, determines the physical section to be tested corresponding to the train to be tested, wherein the physical section to be tested includes a target axle counting section, and the target axle counting section includes a target turnout; when the occupancy state of the physical section to be tested is occupied, a turnout position check is performed on the target axle counting section according to the current turnout position of the target turnout, and when the target axle counting section satisfies the turnout position check, an intrusion detection is performed on the target axle counting section to obtain a first detection result; based on the first detection result, safety protection processing is performed on the train to be tested.

[0130] In this way, by determining the physical section to be tested corresponding to the train to be tested based on mobile authorization, the target axle counting section can be detected for limit intrusion based on the occupancy status of the physical section to be tested, thereby improving detection efficiency and accuracy; by performing a switch position check on the target axle counting section according to the current switch position of the target switch when the occupancy status of the physical section to be tested is occupied, and performing limit intrusion detection on the target axle counting section when the target axle counting section meets the switch position check, limit intrusion detection can be achieved based on information such as the switch position, physical section occupancy status, and axle counting section occupancy status during train operation, without relying on configuration tables or pre-configuration of protection data, thereby reducing maintenance costs, improving system flexibility, and realizing real-time protection during train operation, realizing switch side protection, and ensuring train driving safety.

[0131] The following combination Figure 3-Figure 8 Taking the application of the train safety protection method provided in this specification in the lateral protection of turnout as an example, the train safety protection method is further described. Figure 3 A flow chart of the processing process of a train safety protection method provided by an embodiment of this specification is shown, which specifically includes the following steps.

[0132] Step 302: Based on the rear position of the train to be tested and the movement authorization, the axle counting section sequence corresponding to the train to be tested is obtained.

[0133] Step 304: traverse each axle counting section in the axle counting section sequence to obtain a target axle counting section including a turnout.

[0134] Step 306: Determine the occupation status of the physical segment where the target axle counting segment is located.

[0135] Step 308: If occupied, execute the first part of protection.

[0136] Step 308 ′: If idle, execute the second part of protection.

[0137] By applying this embodiment, during the actual operation of the train, the axle counting section sequence corresponding to the train to be tested can be obtained according to the rear position of the train to be tested and the movement authorization, the target axle counting section with a switch can be obtained from the axle counting section sequence, and the target axle counting section can be protected from the switch. By determining whether the first part of the protection or the second part of the protection is to be executed based on the occupancy status of the physical section where the target axle counting section is located, the accuracy and efficiency of the switch side protection can be improved.

[0138] On this basis, the following Figure 4-Figure 6 Further explain the specific processing logic of the first part of the protection; Figure 7-Figure 8 The specific processing logic of the second part of the protection is further explained.

[0139] Figure 4 A flowchart of the processing process of the first part of the protection of a train safety protection method provided by an embodiment of this specification is shown, which specifically includes the following steps.

[0140] Step 402: When the target axle counting section satisfies the switch position check, the occupancy state of the target axle counting section is determined to be occupied, and the occupancy state of the associated axle counting section is determined to be idle.

[0141] Step 404: Detect whether the train to be tested is currently located in the target axle counting section.

[0142] Optionally, when the train is currently located in the target axle counting section, the following steps 406 to 414 are executed; when the train is not currently located in the target axle counting section, the following steps 406 ′ to 408 ′ are executed.

[0143] Step 406: When there is position information of other trains in the associated axle counting section, the train to be tested is controlled to perform emergency braking.

[0144] Step 408: When there is no position information of other trains in the associated axle counting section, a turnout type check is performed on the target axle counting section and an axle counter type check is performed on the associated axle counting section.

[0145] Step 410: When the target axle counting section satisfies the turnout type check and the associated axle counting section satisfies the axle counter type check, determine whether there is a turnout in the adjacent axle counting section of the associated axle counting section.

[0146] Step 412: When there is no turnout in the adjacent axle counting section, or when there is a turnout in the adjacent axle counting section and the turnout position check is satisfied, determine the occupation status of the adjacent axle counting section.

[0147] Step 414: When the occupancy status of the adjacent axle counting section is occupied, emergency braking of the train to be tested is controlled.

[0148] The following is a method for implementing turnout side protection when the train to be tested is not currently located in the target axle counting section, that is, the physical section is not occupied by the train to be tested entering the target axle counting section.

[0149] Step 406 ′: update the occupancy state of the target axle counting section to a non-communication vehicle occupancy state.

[0150] Step 408 ′: Control the distance between the train to be tested and the target axle counting section to be one axle counting section.

[0151] By applying this embodiment, by performing the first part of protection on the target axle counting section when the physical section where the target axle counting section is located is occupied, it is possible to implement switch side protection for the associated axle counting section and the intrusion area based on information such as the switch position, switch type, axle counter type, and section occupancy status, thereby ensuring train safety, and not relying on the configuration table, reducing maintenance costs and improving system flexibility.

[0152] See also Figure 5 , Figure 5 A schematic diagram of a scenario of first part protection provided by an embodiment of this specification is shown.

[0153] like Figure 5 As shown, DC1 is the positioning, DC2 is the reverse positioning, AC1 and AC2 form a physical section, and AC3 and AC4 form a physical section. AC1 is the axle counting section between axle counter a1 and axle counter a2; AC2 is the axle counting section between axle counter a1 and axle counter a5; AC3 is the axle counting section between axle counter a4 and axle counter a5; AC4 is the axle counting section between axle counter a3 and axle counter a5.

[0154] At this time, another vehicle enters and occupies two other physical sections. The required turnout status of AC1 and AC3 is consistent with the actual turnout status, so LC determines that AC1 and AC3 are occupied, and AC2 and AC4 are idle. AC1 only has an occupied status, but no train position. In the end, AC1 is determined to be occupied by a non-communication vehicle, and the MA of the vehicle to be judged needs to be separated from AC1 by one axle counter. Therefore, when other vehicles enter the associated axle counter AC2 of the front axle counter AC1, the first part of the protection of the side area of ​​the turnout is completed (i.e., the associated axle counter occupation protection).

[0155] See also Figure 6 , Figure 6 A schematic diagram of another scenario of first part protection provided by an embodiment of this specification is shown.

[0156] There is a single-action turnout DC1 in the section where the vehicle to be judged is located. At this time, the associated axle counter AC2 of AC1 has not entered other trains. LC queries the attribute of the axle counter b on the other side of AC2, which is an intrusion axle counter, and the DC2 reverse state required by AC3 is consistent with the actual DC2 reverse state. Then LC queries the occupied state of AC3 and finds that it is occupied. Then LC sends an emergency braking command to the train to be judged.

[0157] Figure 7 A flowchart of the processing process of the second part of the protection of a train safety protection method provided by an embodiment of this specification is shown, which specifically includes the following steps.

[0158] Step 702: When the target axle counting section satisfies the turnout type check and the associated axle counting section satisfies the axle counter type check, it is determined whether there is a turnout in the adjacent axle counting section of the associated axle counting section.

[0159] Step 704: When there is no turnout in the adjacent axle counting section, or when there is a turnout in the adjacent axle counting section and the turnout position check is satisfied, determine the occupation status of the adjacent axle counting section.

[0160] Step 706: When the occupancy status of the adjacent axle counting section is occupied, the train to be tested is controlled not to enter the target axle counting section.

[0161] By applying this embodiment, by performing the second part of protection on the target axle counting section when the physical section where the target axle counting section is located is idle, it is possible to implement side switch protection for the restricted area based on information such as the switch position, switch type, axle counter type, and section occupancy status, thereby ensuring train safety and not relying on the configuration table, reducing maintenance costs and improving system flexibility.

[0162] See also Figure 8 , Figure 8 A schematic diagram of a scenario of second part protection provided by an embodiment of this specification is shown.

[0163] AC1 is the axle counter to be judged. AC1, AC2, and AC3 together form a physical section, which is idle. LC finds that AC1 contains two switches, DC1 and DC2, by querying the electronic map data. First, judge DC1. If DC1 and DC4 are double-action switches, the switch will not be processed, even if there is an intrusion axle counter J2 between them. Then judge DC2. If DC2 is a single-action switch, judge whether the attribute of the axle counter J1 on the other side of the switch-associated axle counter is an intrusion axle counter. If it is not an intrusion axle counter, it will not be processed. However, as shown in the figure, J1 is an intrusion axle counter. Then LC queries the next axle counter AC5 of the associated axle counter. There is a switch. The DC3 state required by AC5 is reversed. If the actual DC3 state is positioned at this time, it will not be processed; if the actual DC3 state is reversed at this time, the occupied state of AC5 is judged. If it is idle, it will not be processed; if it is occupied, the current vehicle is not allowed to enter the AC1 to be judged.
