Anti-collision parking device mitigation method, device and storage medium

Abstract

The embodiments of the present invention disclose a method, device, and storage medium for preventing collisions. The parking system includes a line base rail 1, an anti-slip parking device 2, a parking device detection device 3, a parking device actuator 4, and a parking device control cabinet 5, which are electrically connected. When the parking device control cabinet 5 receives a release command, it executes a single-control mode for three groups of parking devices. When the parking device control cabinet 5 detects that there are vehicles at the two anti-slip parking devices 2 at both ends of the line base rail, but no vehicles at the middle anti-slip parking device 2, the parking device actuator 4 controls the parking devices without vehicles to release the vehicle, while the parking devices with vehicles remain braked. When the parking device control cabinet 5 detects a signal confirming the arrival of a shunting locomotive, the parking device actuator 4 controls the three anti-slip parking devices 2 to release the vehicle. By controlling the parking devices individually, different trains can be controlled to avoid collisions, thereby preventing the "hook-snapping" phenomenon caused by collisions between trains.

[0002] In some marshalling yards, affected by the terrain, when the parking device control system is automatically linked with the integrated automation system of the marshalling yard, the parking device is immediately released after the shunting locomotive passes the signal and enters the shunting section. If the track has a slope, the marshaled vehicles will slip, and at this time the shunting locomotive has not yet connected to the vehicles, causing a collision between the vehicles and the shunting locomotive.

[0029] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and Examples. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is merely to provide a better understanding of the present invention by illustrating examples of the present invention.

[0030] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or device. In the absence of further limitations, the elements defined by the phrase "comprising..." do not exclude the presence of other identical elements in the process, method, article, or device comprising the elements.

[0031] In some marshalling yards, affected by the terrain, when the parking device control system is automatically linked with the integrated automation system of the marshalling yard, the parking device is immediately released after the shunting locomotive passes the signal and enters the shunting section. If the track has a slope, the marshaled vehicles will slip, and at this time the shunting locomotive has not yet connected to the vehicles, causing a collision between the vehicles and the shunting locomotive.

[0032] However, the existing parking brake control device only has the functions of controlling the parking brake release, automatic joint control of the integrated automation system of the marshalling yard and parking brake status monitoring. It cannot avoid the occurrence of collisions and easily causes the "hook-snaking" phenomenon of collisions between trains.

[0033] Embodiments of the present invention provide a collision-preventing parking brake mitigation method, device, and storage medium. By individually controlling parking brakes, different trains can be controlled to mitigate collisions and avoid "hook-snapping" between trains. Specifically, this method improves the parking brake control logic for the existing parking brake control system, which is automatically linked to the marshalling yard integrated automation system. This prevents the "hook-snapping" problem caused by vehicles sliding after parking brake mitigation has occurred while the locomotive is not in position.

[0034] The technical solutions provided by the embodiments of the present invention are described below with reference to the accompanying drawings.

[0035] Figure 1 This is a flow chart of a method for mitigating a collision-proof parking device provided by an embodiment of the present invention. The method is applied to a parking device system. The structure of the parking device system is shown in FIG. Figure 2 As shown;

[0036] Combine Figure 1 and Figure 2 , the structure of the parking system is:

[0037] The parking system includes two parallel track rails 1 spaced a certain distance apart. Three anti-slip parking devices 2 are arranged on the inner side of the parallel track rails in the direction in which the track rails extend. Each anti-slip parking device 2 is provided with a parking device detection device 3. Each anti-slip parking device corresponds to a parking device actuator 4 and is mechanically connected thereto. Each parking device actuator 4 is electrically connected to a parking device control cabinet 5.

[0038] The method may specifically include:

[0039] S101: When the parking device control cabinet 5 receives a release command, the three parking devices are controlled in single control mode;

[0040] S102: The parking device control cabinet 5 detects the parking status of the three anti-slip parking devices 2 based on the parking device detection device 3 provided in each anti-slip parking device 2;

[0041] S103: When the parking device control cabinet 5 detects that there are vehicles at the anti-slip parking devices 2 at both ends of the extension direction of the line foundation rail and there is no vehicle at the anti-slip parking device 2 in the middle, the parking device actuator 4 controls the parking devices without vehicles to release the brakes and keeps the parking devices with vehicles in the parking state braked;

[0042] S104: When the parking device control cabinet 5 detects the shunting machine arrival confirmation signal, the parking device actuator 4 controls the three anti-slip parking devices 2 to release the vehicle.

[0043] In some embodiments, the method further comprises:

[0044] When the parking control cabinet 5 detects based on the parking detection device 3 that there are vehicles at the anti-slip parking devices 2 at both ends in the extension direction of the line foundation rail and there is no vehicle at the middle anti-slip parking device 2, the parking actuator 4 controls the three anti-slip parking devices 2 to maintain braking.

[0045] In some embodiments, the method further comprises:

[0046] When the parking device control cabinet 5 does not receive a release command, the parking device actuator 4 performs joint control of the three parking devices and maintains the braking position.

[0047] In some embodiments, after the parking device control cabinet 5 detects the shunting machine arrival confirmation signal and the three anti-slip parking devices 2 are relieved, the method further includes:

[0048] When the parking device control cabinet 5 receives the braking command, the parking device actuator 4 controls the three anti-skid parking devices 2 to brake and restore the joint control mode.

[0049] In some embodiments, the method further comprises:

[0050] When the parking device control cabinet 5 does not receive a release command, the three parking devices are controlled in conjunction and maintain the braking position.

[0051] Figure 3 This is a flow chart of another anti-collision parking device mitigation method provided by an embodiment of the present invention, combined with Figure 3 The anti-collision parking device mitigation method may specifically include: S1, three groups of parking devices on a track are in a joint control state and maintain the brake position. After a vehicle shunting from a hump enters the parking device, the vehicle wheels are slowly decelerated by the friction of the parking device brake rails until it stops. The parking device detection device with a "parking indication" function on the parking device sends the parking status of the parking device in this group to the parking control system;

[0052] S2, when the shunting locomotive receives a shunting order, it enters the shunting section from the end of the marshaling through the signal. When the system receives the release instruction, it automatically switches to single control mode. The control cabinet releases the parking device without a vehicle first and gives a release in place signal according to the status given by the "parking vehicle indication". The other parking devices remain braked, and the shunting locomotive begins to enter the parking device section. When the shunting locomotive reaches the front end of the parking device with a vehicle, the shunter (or driver) notifies the marshaling section chief, who operates the parking device control interface to confirm that the locomotive is in place (this process can also be completed automatically through the vehicle-ground linkage control device). The parking device control system automatically releases the parking device with a vehicle. At this time, all parking devices are in the release state, and the shunting locomotive begins to connect and pull out the vehicle.

[0053] S3, the shunting locomotive pulls out of the shunting section. After passing the signal, the system receives a braking command again, controls all parking devices to resume braking, and the system returns to the joint control mode. The parking device detection device on the parking device sends the parking status of this group of parking devices to the parking device control system.

[0054] In addition, because the station had carried out a specific shunting operation, there were cars on the front and rear parking brakes, but no car on the middle parking brake. At this time, the shunting locomotive performed shunting operations again. After the parking brake control system received the release command, none of the three groups of parking brakes performed the release action, and then the operation was carried out according to the manual confirmation process.

[0055] Examples, such as Figure 1 As shown, an anti-slip parking device 2 is installed with three groups of parking devices at standard distances at the end of a hump, and parking device detection devices 3 with a "parking indication" function are installed on the three groups of parking devices.

[0056] The parking brake control system is automatically linked to the integrated automation system of the marshalling yard and is equipped with a human-machine interaction system. The parking brake detection device 3 transmits the detected data to the parking brake control cabinet in real time and displays it in real time on the human-machine interaction system. The parking brake actuator 4 controls the braking or release of the parking brake.

[0057] When the parking device 2 is in the braking position, the wheelset 5 of the shunting vehicle enters the parking device from the hump direction; after receiving the shunting order, the wheelset 6 of the shunting locomotive enters the parking device from the tail direction.

[0058] The present invention also provides a method for controlling a railway hump tail stopper to prevent "hooking hooks", comprising the following steps:

[0059] 1. Three groups of parking devices on a track are in joint control and maintain the brake position. When a vehicle shunting from a hump enters a parking device, the vehicle's wheels are slowly decelerated by the friction of the parking device's brake rails until it stops. The parking device detection device with a "parking indication" function on the parking device sends the parking status of this group of parking devices to the parking device control system;

[0060] 2. When the shunting locomotive receives a shunting order and enters the shunting section from the tail end through the signal, the system automatically switches to single control mode after receiving the release command. The control cabinet first releases the parking device without a vehicle and gives a release in place signal according to the status given by the "parking vehicle indication". The other parking devices remain braked, and the shunting locomotive begins to enter the parking device section. When the shunting locomotive reaches the front end of the parking device with a vehicle, the shunter (or driver) notifies the head of the tail section, who operates the parking device control interface to confirm that the locomotive is in place (this process can also be completed automatically through the vehicle-ground linkage control device). The parking device control system automatically releases the parking device with a vehicle. At this time, all parking devices are in the released state, and the shunting locomotive begins to connect and pull out the vehicle.

[0061] 3. After the shunting locomotive is pulled out of the shunting section and passes the signal, the system receives a braking command again, controls all parking devices to resume braking, and the system returns to the joint control mode. The parking device detection device on the parking device sends the parking status of this group of parking devices to the parking device control system.

[0062] 4. Because the station yard has carried out a specific shunting operation, there are cars on the front and rear parking brakes, but no car on the middle parking brake. At this time, the shunting locomotive performs shunting operations again. After the parking brake control system receives the release command, none of the three groups of parking brakes perform the release action. Then the operation is carried out according to the manual confirmation process.

[0063] In summary, due to the adoption of the above technical scheme, the beneficial effects of the present invention are: a parking device control method is proposed to prevent "hooking hooks", which can improve the parking device control logic of the existing parking device control system and the marshalling yard integrated automation system during automatic joint control, and avoid the defect of "hooking hooks" caused by the vehicle slipping after the locomotive is not in place and the parking device is relieved. At the same time, the structural design of the present invention is reasonable and simple, the cost is low, it is easy to implement, and it is suitable for popularization and application.

[0064] The present invention discloses a method for alleviating collision-proof parking brakes, which is applied to parking brake systems. The system consists of a parking brake control cabinet with three groups of parking brake joint control and single control functions, and a parking brake detection device with a "parking car indication" function. The system is initially in joint control mode. When the system receives a relief command, the system automatically switches to single control mode. The control cabinet first relieves the parking brakes without vehicles parked and gives a relief in place signal based on the status given by the "parking car indication" (because the station has carried out a specific shunting operation, there are vehicles on the front and rear parking brakes, but no vehicle on the middle parking brake, so it is considered that there are vehicles on all three groups of parking brakes). The other parking brakes remain braked, and the shunting locomotive begins to enter the parking brake section. When the shunting locomotive reaches the front of a vehicle-carrying stop, the shunter (or driver) notifies the marshaling section chief, who then confirms the locomotive's position by operating the stop control interface (this process can also be automated via the train-to-ground interlocking control system). The system then automatically releases the vehicle-carrying stop. All stops are now released, and the shunting locomotive begins to connect and pull out the vehicle. When the system receives another braking command, it controls all stops to resume braking, returning the system to interlocking control mode. By individually controlling the stops, different trains can be controlled, avoiding collisions and, in turn, preventing "hooking hooks" between trains. The present invention features a rational and simple structural design, low cost, and ease of implementation, making it suitable for widespread application.
