Description

Technical Field

[0001] This invention relates to the field of rail transit technology, and in particular to a train entry control method, device, electronic equipment, and storage medium. Background Technology

[0002] Train entry into the depot is a crucial part of the normal operation of urban rail transit trains. Traditional methods primarily involve information exchange through the interlocking system. This process involves retrieving and traversing the dispatch schedule to determine the train information and entry details for trains currently awaiting entry. The entry information is then sent to the trains waiting to enter the depot, enabling them to perform the entry operation accordingly. However, this traditional method has several drawbacks. First, the interlocking system interaction involves numerous devices, making the information processing overly cumbersome. Second, when the location corresponding to the entry information is occupied by another train, dispatchers must manually select a new parking location and park the train, significantly reducing train entry efficiency and increasing labor costs.

[0003] Therefore, how to better control train entry into the depot has become a technical problem that the industry urgently needs to solve. Summary of the Invention

[0004] This invention provides a train entry control method, device, electronic equipment, and storage medium for better train entry control.

[0005] This invention provides a train entry control method, comprising:

[0006] Once a communication connection is established between the Train Management Center (TMC) and the Object Controller (OC), the target garage to which the train will enter is determined based on the TMC and the OC, and the operation of the signal equipment on the train's route to the target garage is controlled.

[0007] Obtain the status of the signal device;

[0008] Once the signal equipment is determined to be in a passable state, the train is controlled to enter the target garage.

[0009] According to a train entry control method provided by the present invention, the step of determining the target depot for the train to enter based on the Train Management Center (TMC) and the Object Controller (OC), and controlling the operation of the signal equipment on the train's route to the target depot, includes:

[0010] The object controller (OC) is invoked to obtain the axle counting section occupancy information on the train's entry route, and the axle counting section occupancy information is sent to the train management center (TMC).

[0011] The Train Management Center (TMC) is invoked to receive the axle counting section occupancy information, and the target depot to be entered by the train is determined based on the axle counting section occupancy information.

[0012] The Train Management Center (TMC) is invoked to drive the turnouts on the train's route to the target depot into position and to drive the signal equipment on the train's route to the target depot into operation.

[0013] According to a train entry control method provided by the present invention, the step of acquiring the status of the signal equipment includes:

[0014] If it is determined that there is no communication connection between the train's onboard controller (VOBC) and the train management center (TMC), the preset sensing system is activated; the preset sensing system is used to perform image recognition on the signal equipment to determine the status of the signal equipment.

[0015] Obtain the status of the signal device output by the preset sensing system.

[0016] According to the train entry control method provided by the present invention, the preset sensing system is specifically used for:

[0017] Images of the target area along the train's route to the target garage were acquired;

[0018] The image is segmented by color, and the region of interest in the segmented image is extracted.

[0019] Based on the feature information of the signal device, the pixel region of the signal device is filtered out from the region of interest; the feature information includes at least the area, shape, and border of the signal device.

[0020] The state of the traffic signal device is determined based on the RGB values ​​of the pixel area of ​​the traffic signal device and the target traffic light RGB threshold; the target traffic light RGB threshold is obtained by statistically analyzing the RGB values ​​of the traffic light of the traffic signal device captured under multiple scene information conditions.

[0021] According to a train entry control method provided by the present invention, the step of acquiring the status of the signal equipment includes:

[0022] Once it is determined that the onboard controller VOBC of the train has established a communication connection with the train management center TMC, the train management center TMC is invoked to obtain the status of the signal equipment.

[0023] According to a train entry control method provided by the present invention, before determining the target depot the train will enter based on the Train Management Center (TMC) and the Object Controller (OC) after establishing a communication connection between the TMC and the OC, and before controlling the operation of the signal equipment on the train's route to the target depot, the method further includes:

[0024] In the event of a communication interruption in the interlocking system, the Train Management Center (TMC) is invoked to establish a communication connection with the Object Controller (OC).

[0025] The present invention also provides a train entry control device, comprising:

[0026] The first control module is used to determine the target garage that the train will enter based on the Train Management Center (TMC) and the Object Controller (OC) when a communication connection is established between the TMC and the OC, and to control the operation of the signal equipment on the train's route to the target garage.

[0027] The first acquisition module is used to acquire the status of the signal device;

[0028] The second control module is used to control the train to enter the target garage when the signal equipment is determined to be in a passable state.

[0029] The present invention also provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the train entry control method described above.

[0030] The present invention also provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the train entry control method as described above.

[0031] The present invention also provides a computer program product, including a computer program that, when executed by a processor, implements the train entry control method as described above.

[0032] The train entry control method, device, electronic equipment, and storage medium provided by this invention establish a communication connection between the Train Management Center (TMC) and the Object Controller (OC). This allows the TMC to directly obtain trackside axle counting system information monitored by the OC, thereby determining in advance the target depot where the train can safely enter. The TMC then controls the operation of the signal equipment along the train's route to the target depot. By acquiring the status of the signal equipment, and determining that the signal equipment is in a passable state, the TMC controls the train to enter the target depot. This eliminates redundant information exchanged with the interlocking system, improving the efficiency of train entry control. Furthermore, it eliminates the need for dispatch personnel intervention, reducing labor costs and further enhancing the intelligence level of train entry control. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0042] In the description of the invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0043] The following is combined Figures 1-7 The present invention describes a train entry control method, apparatus, electronic device, and storage medium.

[0044] Figure 1 This is one of the flowcharts illustrating the train entry control method provided by the present invention, such as... Figure 1 As shown, it includes:

[0045] Step 110: After confirming that the Train Management Center (TMC) and the Object Controller (OC) have established a communication connection, the target garage to which the train will enter is determined based on the TMC and the OC, and the operation of the signal equipment on the train's route to the target garage is controlled.

[0046] Step 120: Obtain the status of the signal equipment;

[0047] Step 130: If the signal equipment is confirmed to be in a passable state, control the train to enter the target depot.

[0048] Specifically, the Train Management Center (TMC) described in this embodiment of the invention serves as a train information management center, capable of acquiring the operational information of all trains on the entire line at any time, including axle occupancy, signal status, and the location information of all trains on the line, thereby preventing drivers from running red lights.

[0049] The object controller (OC) described in this embodiment of the invention is responsible for receiving trackside object resource control commands from the onboard and intelligent train supervision (ITS) systems, including turnouts, platform emergency stop buttons, etc., and realizing the collection and control of trackside object status.

[0050] The target garage described in this embodiment of the invention refers to a garage used to control the entry and parking of trains, in which no other trains occupy the space.

[0051] The traffic signal equipment described in this embodiment of the invention includes two states: a passable state and a prohibition state. When the traffic signal equipment is in the passable state, a green light will illuminate; when the traffic signal equipment is in the prohibition state, a red light will illuminate.

[0052] It should be noted that the method of the present invention can be applied to the Communication Based Train Control System (CBTC) and the Train Autonomous Circumvention System (TACS).

[0053] TACS does not deploy axle counting equipment on the main track section; instead, it deploys entrance axle counting sections and entrance signals only in the transition section from the depot to the main track. Generally, the entrance axle counting section only requires two axle counting devices, thus significantly reducing the total number of axles counted along the entire line.

[0054] Figure 2 This is a schematic diagram of interlocking communication in the vehicle-to-vehicle communication system provided by the present invention, as shown below. Figure 2 As shown, under normal circumstances, the TMC and OC do not communicate directly. They operate according to the normal interlocking logic. The OC communicates with the TMC through the Resource Controller (RC) to send trackside information to the TMC. Simultaneously, the Automatic Train Supervision (ATS) issues designated train entry commands to the Intelligent Vehicle On-based Controllers (IVOCs) of each train. The IVOC reports its communication status with the RC to the ATS in real time. The ATS reports the communication status of the train, the ATS, and the RC to the gateway. The gateway receives the trackside information sent by the TMC, uploads the trackside information to the ATS, and simultaneously sends communication information of each device to the TMC, issuing designated train entry commands.

[0055] Among them, RC uses sections as train operation resources, divides the resource start and end points into logical sections, and manages train operation resources by allocating, applying for, requisitioning, and releasing logical sections and trackside resources.

[0056] In an embodiment of the present invention, a communication link is established between the TMC and the OC. In step 110, when it is determined that the TMC and the OC have established a communication connection, the TMC and the OC can directly communicate data. The TMC can directly obtain the trackside information collected by the OC. Based on the trackside information, the TMC determines the target garage that the train can enter and controls the operation of the signal equipment on the train's route to the target garage to instruct the train to enter the garage.

[0057] Furthermore, in an embodiment of the present invention, in step 120, the status of the signal equipment is obtained so as to control the start and stop operation of the train according to the status of the signal equipment.

[0058] Based on the above embodiments, as an optional embodiment, step 120, obtaining the status of the signal device, includes:

[0059] Once it is confirmed that the train's onboard controller VOBC has established a communication connection with the train management center TMC, the status of the signal equipment is obtained by calling the train management center TMC.

[0060] Specifically, in the embodiments of the present invention, when it is determined that the train VOBC and TMC have established a communication connection, it is explained that communication is established between the TMC and the train. At this time, the status of the signal equipment can be directly obtained through the TMC. After obtaining the status of the signal equipment, the TMC can send the status information of the signal equipment to the train VOBC. That is, the TMC can directly transmit the status of the signal to the train in the form of electrical signals, so that the train VOBC can control the start and stop of the train according to the status of the signal equipment.

[0061] The method of this invention establishes communication between the TMC and the train, calls the TMC to directly obtain the status of the signal equipment, and sends it to the train VOBC to control the start and stop of the train. This method can quickly and accurately obtain the status of the signal equipment, which is beneficial to improving the efficiency and accuracy of subsequent train entry control.

[0062] However, there is usually only one TMC on the entire line. Establishing communication with any train at the depot through the TMC may fail due to distance or other factors, which may prevent the signal status information from being sent to the train system.

[0063] Therefore, based on the content of the above embodiments, as an optional embodiment, in step 120, obtaining the status of the signal device, the method may further include:

[0064] If it is determined that there is no communication connection between the train's onboard controller (VOBC) and the train management center (TMC), the pre-set sensing system is activated; the pre-set sensing system is used to perform image recognition on the signal equipment to determine the status of the signal equipment.

[0065] Obtain the status of the signal equipment output by the preset sensing system.

[0066] Specifically, the pre-set sensing system described in this embodiment of the invention refers to an image sensing and recognition system pre-installed on the train, which is used to perform image recognition on signal equipment and identify the status of the signal equipment. Specifically, it can be achieved by installing image acquisition devices such as cameras on the top of the train's front to acquire images of the signal equipment on the route ahead of the train, and then performing image recognition on the images of the signal equipment to output the status of the signal equipment.

[0067] Furthermore, in the embodiments of the present invention, if it is determined that there is no communication connection between the train's onboard VOBC and TMC, it indicates that the communication between the train's onboard VOBC and TMC is interrupted. The onboard VOBC cannot receive the signal equipment status information sent by the TMC. At this time, a preset sensing system can be activated. Through the preset sensing system, image recognition is performed on the lighting status of the signal equipment in the train's route direction to determine the status of the signal equipment.

[0068] The method of this invention utilizes image recognition technology to perform image recognition on the signal equipment on the train's route ahead, identifying the lighting status of the signal equipment. This effectively identifies the status of the signal equipment, avoiding situations where the TMC and the train's onboard VOBC cannot communicate, resulting in the train being unable to obtain the status of the signal equipment. This further improves the reliability and stability of train entry control.

[0069] Based on the above embodiments, as an optional embodiment, the preset sensing system is specifically used for:

[0070] Acquire images of the target area along the train's route to the target depot;

[0071] Perform color segmentation on the image and extract the region of interest from the segmented image;

[0072] Based on the feature information of the signal equipment, filter out the pixel region of the signal equipment from the region of interest; the feature information includes at least the area, shape and border of the signal equipment.

[0073] The status of the traffic signal equipment is determined based on the RGB values ​​of the pixel area of ​​the traffic signal equipment and the RGB threshold of the target traffic light; the RGB threshold of the target traffic light is obtained by statistical analysis of the RGB values ​​of the traffic light of the traffic signal equipment captured under multiple scene information conditions.

[0074] Specifically, the target area described in the embodiments of the present invention refers to the area covered by the signal equipment when the image acquisition device captures images on the train's route to the target depot.

[0075] The various scene information described in the embodiments of this invention refers to information about different environmental scenarios in which the signal equipment is located, which may include different environmental scenarios such as rainy days, sunny days, cloudy days, and snowy days.

[0076] The target traffic light RGB threshold described in this embodiment of the invention refers to the color threshold obtained by statistically analyzing the RGB values ​​of traffic lights based on images taken from traffic signal equipment under various scene information.

[0077] In an embodiment of the present invention, the specific steps of the preset sensing system for image recognition of the status of signal equipment are as follows.

[0078] In an embodiment of the present invention, an image acquisition device, such as a camera, can be used in a pre-installed sensing system to acquire images of the target area on the train's approach to the target garage, and obtain images containing pixel information of the signal equipment.

[0079] Furthermore, in an embodiment of the present invention, the image of the target area is color-segmented, and the region of interest of the color-segmented image is extracted. Specifically, in order to eliminate noise, illumination, and other interference factors, the image of the train captured by the camera first needs to be histogram equalized. That is, the data of each channel is first histogram equalized, and then merged into a 3-channel image, mainly targeting the data of the R (Red), G (Green), and B (Blue) channels.

[0080] Color characteristics are one of the most important and prominent features of traffic signal equipment. To perform color segmentation on a target area containing traffic signal equipment, a suitable color space must first be selected. Since the R, G, and B components in the RGB color space are highly correlated and significantly affected by lighting, they are unfavorable for color segmentation. Therefore, in this embodiment of the invention, the RGB three-channel data can be normalized: R = R / (R+G+B), G = R / (R+G+B), B = R / (R+G+B), thereby segmenting the red and green channels. Then, the R, G, and B values ​​of the red and green lights of the traffic signal equipment captured under different environmental conditions in various scenarios are statistically analyzed to determine the color threshold of the traffic signal indicator, thus obtaining the target traffic light RGB threshold.

[0081] Furthermore, in an embodiment of the present invention, the connected regions of the segmented red channel image and green channel image are labeled to obtain the region of interest, and the basic geometric features of the region are extracted, such as length, width, aspect ratio, area (i.e., number of white pixels), etc. All feature information is extracted and stored for identification and determination of the signal equipment status.

[0082] Understandably, geometric features are another significant characteristic of signal equipment. Although different climates and environments may produce varying degrees of noise in image acquisition, the geometry and dimensions of signal equipment remain largely unchanged.

[0083] Furthermore, based on the feature information of the traffic signal equipment, including at least its area, shape, and border, multi-feature matching can be performed to effectively filter out the pixel region where the traffic signal equipment is located from the region of interest. Then, by determining whether the RGB values ​​of the pixel region of the traffic signal equipment fall within the target traffic light's RGB threshold range, it can be determined whether the traffic signal equipment is in a green light (go) or red light (stop) state.

[0084] The method of this invention, by performing image segmentation and RGB normalization on the image of the signal equipment, can reduce the difficulty of identifying the signal equipment due to the variability and complexity of the scene within the track. Furthermore, based on feature matching, the state of the signal equipment can be further identified, effectively filtering out interference areas in the image and quickly and accurately detecting and identifying the state of the signal equipment.

[0085] Furthermore, in an embodiment of the present invention, in step 130, if it is determined that the signal device is in a passable state, that is, the signal device lights up green and it is passable, then the train can be controlled to safely enter the target garage.

[0086] It should be noted that for TACS, when a train successfully enters the target garage via vehicle-to-vehicle communication, it can share its own location information and garage information with the following train, making it easier for the following train to enter the garage. This eliminates the need to rely on the trackside axle counting system information provided by OC to determine the target garage for the train, which can further improve the efficiency of multiple trains entering the garage.

[0087] The train entry control method, device, electronic equipment, and storage medium provided by this invention establish a communication connection between the Train Management Center (TMC) and the Object Controller (OC). This allows the TMC to directly obtain trackside axle counting system information monitored by the OC, thereby determining in advance the target depot where the train can safely enter. The TMC then controls the operation of the signal equipment along the train's route to the target depot. By acquiring the status of the signal equipment, and determining that the signal equipment is in a passable state, the TMC controls the train to enter the target depot. This eliminates redundant information exchanged with the interlocking system, improving the efficiency of train entry control. Furthermore, it eliminates the need for dispatch personnel intervention, reducing labor costs and further enhancing the intelligence level of train entry control.

[0088] Based on the above embodiments, as an optional embodiment, the train management center (TMC) and object controller (OC) determine the target depot the train will enter and control the operation of the signal equipment on the train's route to the target depot, including:

[0089] Call the object controller (OC) to obtain the axle counting section occupancy information on the train's entry route, and send the axle counting section occupancy information to the train management center (TMC);

[0090] The Train Management Center (TMC) is invoked to receive axle section occupancy information, and the target depot for the train is determined based on the axle section occupancy information.

[0091] The Train Management Center (TMC) is invoked to drive the train to the target depot, and the turnouts on the route to the target depot are put into position. The signal equipment on the route to the target depot is also activated.

[0092] Specifically, the axle counting section occupancy information described in this embodiment of the invention refers to the usage status information of the axle counting section. The axle counting section refers to the physical section between two axle counting heads. Based on the axle counting section occupancy information, it can be determined whether the axle counting section is in an idle state or in a state where a vehicle occupies it.

[0093] In an embodiment of the invention, by directly communicating between the TMC and OC and calling the OC to monitor trackside information, the occupancy information of axle counting sections along the train's entry route can be obtained. This allows the determination of the usage status of each axle counting section along the train's entry route, identifying which axle counting sections are idle and which are occupied by trains, and then sending this occupancy information to the TMC. Furthermore, after receiving this axle counting section occupancy information, the TMC can determine whether a train has already entered each depot, thereby filtering out idle depots and identifying the target depot for the train's entry.

[0094] Furthermore, in an embodiment of the present invention, after determining the target garage that the train is about to enter, the TMC can be invoked to drive the various switches on the train's route to the target garage into position, ensuring that the train can safely enter the target garage. At the same time, the signal equipment on the train's route to the target garage is activated to guide the train's safe operation.

[0095] The method of this invention enables efficient control and safe operation of train entry into the depot by communicating and interacting with the Train Management Center (TMC) and the Object Controller (OC) through data such as trackside information, axle occupancy information, and turnout positioning information. This eliminates the need for dispatch personnel intervention and improves the intelligence level of train entry control.

[0096] In existing technologies, when the interlocking system and all equipment malfunction and communication is interrupted, the entire system will be paralyzed. The train can only be downgraded and then slowed down to a stop. If the train fails to stop and crashes into a depot where there are already trains, a safety accident will occur. Even if the train can stop in time, if the interlocking system fails to communicate, the train will remain stationary. The train can only be driven into the corresponding depot by manually moving the switches to the corresponding positions, which requires a lot of manpower, greatly affects operational efficiency, and brings certain safety risks.

[0097] Therefore, based on the above embodiments, as an optional embodiment, after determining that the Train Management Center (TMC) and the Object Controller (OC) have established a communication connection, before determining the target depot the train will enter based on the TMC and the OC, and controlling the operation of the signal equipment on the train's route to the target depot, the method further includes:

[0098] In the event of a confirmed interlocking system communication interruption, the Train Management Center (TMC) is invoked to establish a communication connection with the Object Controller (OC).

[0099] Figure 3 This is a schematic diagram of interlocking communication interruption in the train entry control method provided by the present invention, as shown below. Figure 3 As shown in the embodiment of the present invention, when the interlocking system communication is interrupted, the OC starts establishing a link with the TMC. At this time, it is necessary to determine that the interlocking host and all devices are not communicating. First, the communication status between the TMC itself and the interlocking can be directly obtained. The communication status between the ATS and the interlocking host can also be transmitted to the TMC through the gateway. The communication status between the vehicle and the interlocking can be added through the interaction between the vehicle and the ATS, transmitted to the gateway through the ATS, and then transmitted to the TMC. When it is detected that all devices and the interlocking have failed to communicate, and the OC has started sending link establishment information to the TMC, it indicates that the interlocking has failed, and the entry detection system needs to be started to establish a communication connection between the TMC and the OC.

[0100] Figure 4 This is the second flowchart of the train entry control method provided by the present invention, as shown below. Figure 4 As shown in the embodiment of the present invention, when it is determined that the interlocking system communication is normal, the train entering the depot is processed according to the normal interlocking logic. If it is determined that the interlocking system communication is interrupted, the TMC is called to establish a link with the OC to establish communication. After the communication starts, the OC needs to upload trackside information such as the occupancy information of all axle counting sections in the train entering the depot route, the turnout position information, and the depot door opening and closing information to the TMC. The TMC can obtain the occupancy information of all axle counting sections in the depot. At the same time, the TMC uploads this trackside information to the ATS dispatching and displaying station information through the gateway.

[0101] Simultaneously, the TMC (Train Management Center) determines whether a train has entered each garage based on the occupancy information of all axle counting sections within the garage. It then drives the switches on the entry route to the correct positions, ensuring that trains about to enter the garage can proceed to the correct target garage. Once the switches are in the correct positions, the indicator lights on the signal equipment on the entry route to the target garage illuminate green. The train then activates its pre-set sensing system, using this system to identify the status of the signal equipment. After recognizing the corresponding indicator light, the train can enter the corresponding target garage.

[0102] Figure 5 This is a schematic diagram of a scenario involving drive signals and turnouts in the train entry control method provided by this invention, as shown below. Figure 5 As shown in the embodiment of the present invention, when the TMC receives trackside information data from the OC, it can detect that there is already a train 2 in the depot 1. However, at this time, the interlocking has been interrupted in communication with all equipment, and the corresponding switches 1 and 2 are still in the reverse position and have not been driven back to the correct position (track straight position). At this time, the TMC needs to take safety precautions to prevent the train 1, which is about to enter the depot, from rushing into the depot 1 and causing a safety accident. Therefore, it drives both switches 1 and 2 to the correct position (safe position). After the train 1 comes to an emergency stop, when controlling the train 1 to enter the depot 2, the TMC needs to drive switch 1 to the reverse position and switch 2 to the correct position. After both switches have been driven to the safe position, the signal equipment 1 and signal equipment 2 are driven to light up green lights, indicating that the train is in a passable state, and thus the train 1 can be instructed to enter the depot 2 ahead.

[0103] The method of this invention addresses situations where interlocking systems experience sudden communication failures with other equipment, or where interlocking equipment is damaged and cannot be immediately repaired. By establishing communication between the Train Control Center (TCC) and the Operating Center (OC), the TMC can obtain trackside axle counting information from the OC. Simultaneously, it drives the turnouts and signal equipment on the entry route section. Through a pre-installed sensing system in the train, it identifies the status information of the signal equipment and determines the passability of the train depot ahead. This enables the train to safely enter the corresponding train depot even when interlocking communication is interrupted, enhancing protection against accidental safety incidents and improving train transportation efficiency. It also prevents trains from being stuck on the entry route section, thus preventing other trains from entering the depot.

[0104] The train entry control device provided by the present invention is described below. The train entry control device described below can be referred to in correspondence with the train entry control method described above.

[0105] Figure 6 This is a schematic diagram of the train entry control device provided by the present invention, as shown below. Figure 6 As shown, it includes:

[0106] The first control module 610 is used to determine the target garage that the train will enter based on the train management center TMC and the object controller OC, and to control the operation of the signal equipment on the train's route to the target garage, after determining that a communication connection has been established between the train management center TMC and the object controller OC.

[0107] The first acquisition module 620 is used to acquire the status of the signal equipment;

[0108] The second control module 630 is used to control the train to enter the target garage when the signal equipment is determined to be in a passable state.

[0109] The train entry control device described in this embodiment can be used to execute the above-described train entry control method embodiment. Its principle and technical effects are similar, and will not be repeated here.

[0110] The train entry control device of this invention establishes a communication connection between the Train Management Center (TMC) and the Object Controller (OC), enabling the TMC to directly obtain trackside axle counting system information monitored by the OC. This allows the TMC to determine in advance which target depot the train can safely enter and control the operation of the signal equipment along the train's route to the target depot. By acquiring the status of the signal equipment, and determining that the signal equipment is in a passable state, the device controls the train to enter the target depot. This eliminates redundant information exchanged with the interlocking system, improving the efficiency of train entry control.
