Abstract
Description
Technical Field
[0001] This application relates to the field of rail transit and railway signal processing technology, and in particular to a method, apparatus and computer interlocking system for visually authorized train routes. Background Technology
[0002] In the current heavy-haul virtual train operation control system, the train starts on the track, the driver inputs departure information through the DMI (Driver-Machine Interface), and the train establishes communication with the Radio Block Centre (RBC). After receiving the train's parameter information, the RBC determines that the train needs to depart with visual authorization; at this point, the train can be called a visually authorized train. The RBC sends a movement authorization to the visually authorized train, and the driver monitors the train's safe operation according to the visual authorization mode and the movement authorization. The condition for the RBC to send a movement authorization to the visually authorized train is that the station's computer interlocking system has locked the route and opened the route signal for the train.
[0003] When processing departure routes, the computer interlocking system at the departure station cannot process multi-train routes because the radio block center system determines that the train is a visually authorized train. If processed as a single-train route, in scenarios where there are communication trains heading to adjacent stations in the section, the section is occupied, causing the route signal to be blocked, affecting the station's throughput capacity. Summary of the Invention
[0004] Therefore, it is necessary to provide a method, device, and station computer interlocking system for visually authorized train routes to address the aforementioned technical problems.
[0005] This application provides a method for processing visually authorized train routes, the steps of which are executed by the departure station's computer interlocking system, the method including:
[0006] In response to the route processing operation of the station operator, the route for the visually authorized train to proceed to the section is processed. After determining that the route meets the single-train route locking conditions, the route is locked. Among the two adjacent stations at both ends of the section, one end station is the departure station and the other end station is the receiving station.
[0007] When the communication with the computer interlocking system at the receiving station determines that the section is the departure direction, and the wireless block center system sends a message indicating that there are no hidden trains in the section, and it is determined that the route meets all the other inspection conditions in the fixed block route opening conditions except for the section direction inspection condition and the section clearing inspection condition, the starting signal of the route is set to the off-light permission state, and a starting signal permission message is sent to the wireless block center system; the starting signal permission message causes the wireless block center system to send a movement authorization to the visually authorized train, instructing the visually authorized train to travel according to the movement authorization;
[0008] When the visually authorized train occupies the approach section and the first section of the route, the starting signal is kept in the off-light permission state. After receiving the information from the radio block center system that the visually authorized train is crossing the starting signal, the starting signal is set to the off-light prohibition state.
[0009] This application provides a processing device for visually authorized train routes, the device comprising:
[0010] The route processing and locking module is used to respond to the route processing operation of the departure station operator, process the route for visually authorized trains to proceed to the section, and lock the route after determining that the route meets the single train route locking conditions; among the two adjacent stations at both ends of the section, one end station is the departure station and the other end station is the receiving station.
[0011] The permission processing module is used to set the starting signal of the route to the off-light permission state and send the starting signal permission information to the wireless block center system when, based on communication with the computer interlocking system of the receiving station, it determines that the section is the departure direction, receives the information that there is no hidden car in the section from the wireless block center system, and determines that the route meets the other inspection conditions in the fixed block route opening conditions except for the section direction inspection condition and the section clearing inspection condition; the starting signal permission information causes the wireless block center system to send a movement authorization to the visually authorized train, so as to instruct the visually authorized train to travel according to the movement authorization.
[0012] The prohibition processing module is used to keep the starting signal in the off-light permission state when the visually authorized train occupies the approach section and the first section of the route, and to set the starting signal to the off-light prohibition state after receiving the information from the radio block center system that the visually authorized train is crossing the starting signal.
[0013] In one embodiment, the apparatus further includes a signal processing module for:
[0014] Receive information from the radio block center system that the starting signal is approaching by the visually authorized train; in response to the information, set the starting signal to a no-lights-out state.
[0015] In one embodiment, the conditions under which the radio block center system transmits information about no hidden vehicles in a section include a first condition or a second condition.
[0016] The first condition is: the radio block center system receives information from the departure station computer interlocking system that the section is in an idle state, and the radio block center system determines that there is no communicating train or non-communicating train in the section;
[0017] The second condition is: the radio block center system receives information from the departure station computer interlocking system that the section is occupied, and the radio block center system determines whether there is a communicating train or a non-communicating train in the section.
[0018] This application provides a computer interlocking system for a departure station, which is used to perform the above-described method.
[0019] The aforementioned method, device, and departure station computer interlocking system for processing visually authorized train routes respond to the route processing operation of the departure station operator, processing the route for visually authorized trains to proceed to the section. After determining that the route meets the single-train route locking conditions, the route is locked. Among the two adjacent stations at both ends of the section, one end station is the departure station, and the other end station is the receiving station. Based on communication with the receiving station's computer interlocking system, it is determined that the section is the departure direction, and information indicating no hidden trains in the section is received from the wireless block center system, and it is determined that the route meets the fixed block route opening conditions except for the section direction check. When other inspection conditions besides the condition of clearing the section are met, the starting signal of the route is set to the off-light permission state, and the starting signal permission information is sent to the radio block center system. The starting signal permission information causes the radio block center system to send a movement authorization to the visually authorized train, instructing the visually authorized train to travel according to the movement authorization. When the visually authorized train occupies the approach section and the first section of the route, the starting signal is kept in the off-light permission state. After receiving the information from the radio block center system that the visually authorized train has crossed the starting signal, the starting signal is set to the off-light prohibition state. This application adds route processing for visually authorized trains to the train route function processed by the traditional computer interlocking system. It is applicable to visually authorized trains using the movement authorization of the radio block center system. This visually authorized train route allows a single train to run on the route. The opening condition includes no hidden cars in the section, thereby avoiding the running conflict between hidden cars and visually authorized trains caused by the presence of hidden cars in the section, ensuring train running safety, and improving station throughput capacity.

[0028] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0029] Computerized interlocking systems are fundamental equipment for railway signaling. They handle both single-train and multi-train routes.
[0030] A single-train route is a type of ordinary train route. This type of route allows only one train to run on the route and in the section. Before the departure signal for the section is opened, the route and the corresponding section must be checked for vacancy.
[0031] A multi-train route is a route that allows multiple trains to run on the route. When the departure signal for a section is opened, it is necessary to check that the first section of the route is free and that there are no hidden trains in the section. It is not necessary to check the occupancy status of other sections within the route.
[0032] Hidden vehicle: The wireless block center system does not have train-related information, has not received any location reports, and cannot confirm the specific location of the train or an unknown vehicle that is virtually created on the track due to equipment failure.
[0033] Communication train: A train that has established a communication session with the radio block center system and is able to report its position.
[0034] Non-communication trains: Trains for which the radio block center system has relevant train information, but the connection between the train and the radio block center system is interrupted or the communication session is terminated, and the radio block center system cannot obtain the updated location report.
[0035] Visually authorized trains: Trains that require visual authorization to start on the track, as the radio block center system has relevant train information.
[0036] The visual authorization train route processing method provided in this application can be applied to the visual authorization train route scheme of the heavy-haul virtual train operation control system. In the heavy-haul virtual train operation control system, the computer interlocking system adds processing for visual authorization train routes, including the entire process from route processing to route unlocking.
[0037] The method provided in this application allows a computer interlocking system to process departure routes for visually authorized trains to travel to an adjacent station when there are communication trains traveling to the next station within the same section.
[0038] A visually authorized train is preparing to depart from one station to another. These two stations are adjacent and correspond to a section of track. One station is the departure station, and the other is the arrival station. Both the departure and arrival stations have their own computer interlocking systems, referred to as the departure station computer interlocking system and the arrival station computer interlocking system, respectively.
[0039] For example, a visually authorized train is preparing to depart from station A to station B. Stations A and B correspond to a section, with station A being the departure station and station B being the arrival station. Both stations A and B have computer interlocking systems; station A's computer interlocking system belongs to the departure station's computer interlocking system, and station B's computer interlocking system belongs to the arrival station's computer interlocking system.
[0040] The methods provided in this application may include Figure 1 Steps S101 to S103 are shown. Steps S101 to S103 can be executed by the departure station computer interlocking system.
[0041] Step S101: In response to the route processing operation of the station operator, the route for the visually authorized train to proceed to the section is processed, and the route is locked after confirming that the route meets the single-train route locking conditions.
[0042] In a section of railway, one of the adjacent stations at each end is the departure station, and the other station is the arrival station.
[0043] In scenarios where there are communication trains traveling to adjacent stations within a section, the computer interlocking system at the departure station can, through the method provided in this application, grant visually authorized trains a route to that section, which is a departure route.
[0044] like Figure 2 As shown, in the section corresponding to the two adjacent stations A and B, there is a train 1 heading towards station B. Train 1 is a communication train. In this scenario, using the method provided in this application, the departure station's computer interlocking system can process a route for train 2 (a visually authorized train) to enter the section, that is... Figure 2 The diagram shows a route from signal X3 to signal S; this route can begin with signal X3, therefore signal X3 can be called the starting signal of the route. Signal S is the ending signal of the route.
[0045] Specifically, Train 2 can be started on the 3G track. The driver of Train 2 inputs departure information in the DMI (Driver Machine Interface), and Train 2 establishes communication with the radio block center system.
[0046] Based on the departure information of train 2, the radio block center system determines that train 2 is a visually authorized train. The radio block center system then sends a message to the computer interlocking system at station A indicating that the starting signal X3 is approaching by a visually authorized train. Upon receiving this message, the computer interlocking system at station A changes the starting signal X3 from the lit-in, prohibited state to the unlit, prohibited state. Figure 3 As shown.
[0047] The station A operator (belonging to the departure station operator) presses X3LA (the button representing the starting signal X3) and SLA (the button representing the ending signal S) in sequence according to the train operation plan. The operation of the station A operator pressing X3LA and SLA in sequence belongs to the route handling operation.
[0048] In response to route processing operations, the A-station computer interlocking system can process routes for visually authorized trains to the designated section. These routes can include the route from the starting signal X3 to the ending signal S, and can be denoted as route X3->S. The A-station computer interlocking system can check route X3->S according to the single-train route locking conditions, which comply with the railway station computer interlocking technical conditions. If route X3->S meets the single-train route locking conditions, the A-station computer interlocking system can lock route X3->S. The schematic lines for route X3->S are shown from... Figure 3 The solid line becomes Figure 4 The dashed line segment.
[0049] Step S102: When the section is determined to be the departure direction based on the communication with the computer interlocking system of the receiving station, and the information that there are no hidden trains in the section is received from the wireless block center system, and when it is determined that the route meets the other inspection conditions in the fixed block route opening conditions except for the section direction inspection condition and the section clearing inspection condition, the starting signal of the route is set to the off-light permission state, and the starting signal permission information is sent to the wireless block center system.
[0050] The initial signal's permission information causes the radio block center system to send a movement authorization to the visually authorized train, instructing the visually authorized train to proceed according to the movement authorization.
[0051] As in the example above, the computer interlocking system at station A can communicate with the computer interlocking system at station B. Through communication, the direction of the section can be determined as the departure direction, that is, the train travels from station A to station B. The direction of this section is consistent with the direction of travel of the visually authorized train.
[0052] In the aforementioned example, train 1 is a communication car, and the radio block center system can obtain the real-time location of train 1. Through communication with train 1, the radio block center system can determine that a communication car is occupying the section. Since train 1 is within the section, the computer interlocking system at station A determines that the section is occupied and sends this information to the radio block center system. The radio block center system, having confirmed the presence of a communication car in the section through communication with train 1 and also receiving the occupied information from the computer interlocking system at station A, can then send a message to the computer interlocking system at station A indicating that there are no hidden cars in the section.
[0053] The opening conditions for a fixed block route include section direction check conditions and section clearing check conditions. The section direction check condition is mainly used to check whether the section direction is the departure direction, and the section clearing check condition is mainly used to check whether the section is in a clearing state. In this application, the computer interlocking system at station A determines that the section direction is the departure direction through the aforementioned exemplary method and receives information from the radio block center system that there are no hidden trains in the section. Therefore, the computer interlocking system at station A does not need to perform checks according to the section direction check conditions and section clearing check conditions in the opening conditions for a fixed block route.
[0054] The computer interlocking system at station A can check route X3->S according to other check conditions in the fixed block route opening conditions, excluding the section direction check condition and the section clearing check condition. This check follows the technical conditions for computer interlocking of railway stations.
[0055] If the computer interlocking system at station A determines that the section is in the departure direction, receives no hidden train information from the radio block center system, and determines that route X3->S meets other check conditions in the fixed block route opening conditions, then the starting signal X3 can be changed from the off-light prohibition state to the off-light permit state. Figure 5 As shown; the computer interlocking system at station A can also send permission information from the starting signal to the radio block center system.
[0056] After receiving permission from the originating signal, the radio block center system sends a movement authorization to train 2. The driver of train 2 then drives the train according to the movement authorization.
[0057] Step S103: When a visually authorized train occupies the approach section and the first section of the route, keep the starting signal in the off-light permission state. After receiving the information from the radio block center system that the visually authorized train is crossing the starting signal, set the starting signal to the off-light prohibition state.
[0058] As in the previous example, during the journey matching the movement authorization, train 2 will occupy the approach section and the first section within route X3->S. The approach section is as follows: Figure 6 The first segment of the IIIG route X3->S shown is as follows: Figure 6 The 2-4DG shown.
[0059] When train 2 occupies the approach section IIIG and the first section 2-4DG, the computer interlocking system at station A can keep the starting signal X3 in the off-light permission state. After receiving the information from the radio block center system regarding train 2 crossing the starting signal X3, the computer interlocking system at station A can change the starting signal X3 from the off-light permission state to the off-light prohibition state. At this time, the starting signal X3 is normally closed.
[0060] After the starting signal X3 is closed normally, as train 2 runs normally, the sections within route X3->S will be unlocked in sections after the "three-point check" conditions are met, until the route is unlocked; if the conditions do not meet the "three-point check" conditions, the "two-point check" conditions can also be used.
[0061] Understandably, in Figure 2 In the corresponding scenarios, the preconditions for the method provided in this application include at least:
[0062] (1) Train 1 communicates normally with the radio block center system. Train 1 can travel normally from station A to station B according to the movement authorization received from the radio block center system.
[0063] (2) The computer interlocking system of Station A communicates normally with the wireless block center system;
[0064] (3) The computer interlocking system of station A and the computer interlocking system of station B communicate normally.
[0065] In the above-mentioned method for handling visually authorized train routes, in response to the route processing operation of the station operator, the route for the visually authorized train to proceed to the section is processed. After confirming that the route meets the single-train route locking conditions, the route is locked. Among the two adjacent stations at both ends of the section, one end station is the departure station and the other end station is the receiving station. Based on the communication with the computer interlocking system of the receiving station, it is determined that the section is the departure direction, and the information that there are no hidden cars in the section is received from the wireless block center system. It is also determined that the route meets the fixed block route opening conditions except for the section direction check condition and the section being clear. When checking conditions other than the standard check conditions, the starting signal of the route is set to the off-light permitted state, and a starting signal permitted information is sent to the radio block center system. The starting signal permitted information causes the radio block center system to send a movement authorization to the visually authorized train, instructing the visually authorized train to travel according to the movement authorization. When the visually authorized train occupies the approach section and the first section of the route, the starting signal remains in the off-light permitted state. After receiving the information from the radio block center system that the visually authorized train is crossing the starting signal, the starting signal is set to the off-light prohibited state. This application adds route processing for visually authorized trains to the traditional train route function processed by the computer interlocking system. It is applicable to visually authorized trains using the movement authorization of the radio block center system. This visually authorized train route allows a single train to run on the route, and the opening condition includes no hidden cars in the section, thereby avoiding the running conflict between hidden cars and visually authorized trains caused by the presence of hidden cars in the section, ensuring train running safety, and improving station throughput capacity.
[0066] In one embodiment, the method provided in this application further includes, prior to processing the visually authorized train route to the section in response to the operation of the station operations officer:
[0067] Receive information from the radio block center system that a visually authorized train is approaching the starting signal; in response to the information, set the starting signal to the off-light prohibition state.
[0068] like Figure 2 As shown, in the section corresponding to the two adjacent stations A and B, there is a train 1 heading towards station B. Train 1 is a communication train. In this scenario, using the method provided in this application, the computer interlocking system at the departure station can process a route for train 2 (a visually authorized train) to enter the section, that is... Figure 2 The route from the starting signal X3 to the exit signal S is shown.
[0069] Specifically, Train 2 can be started on the 3G track, the driver of Train 2 enters the departure information in the DMI, and Train 2 establishes communication with the radio block center system.
[0070] Based on the departure information of train 2, the radio block center system determines that train 2 is a visually authorized train. The radio block center system then sends a message to the computer interlocking system at station A indicating that the starting signal X3 is approaching by a visually authorized train. Upon receiving this message, the computer interlocking system at station A changes the starting signal X3 from the lit-in, prohibited state to the unlit, prohibited state. Figure 3 As shown.
[0071] In one embodiment, the conditions under which the radio block center system sends information about no hidden trains in a section include a first condition or a second condition. The first condition is that the radio block center system receives information from the departure station's computer interlocking system indicating that the section is idle, and the radio block center system determines that there is no communicating or non-communicating train in the section. The second condition is that the radio block center system receives information from the departure station's computer interlocking system indicating that the section is occupied, and the radio block center system determines that there is a communicating or non-communicating train in the section.
[0072] Taking the computer interlocking system at the departure station as an example, the following explanation is provided: If the radio block center system determines that there is no communicating or non-communicating train in the section and receives information from the computer interlocking system at station A indicating that the section is idle, it can send information indicating that there is no hidden train in the section to the computer interlocking system at station A; or, if the radio block center system determines that there is a communicating or non-communicating train in the section and receives information from the computer interlocking system at station A indicating that the section is occupied, it can send information indicating that there is no hidden train in the section to the computer interlocking system at station A.
[0073] In one embodiment, after receiving information from the radio block center system regarding the visual authorization of a train crossing the starting signal, setting the starting signal to a no-light, prohibited state includes:
[0074] After receiving information from the radio block center system regarding a visually authorized train crossing the starting signal, the system determines whether the visually authorized train has crossed the signal based on real-time collected information; if so, the starting signal is set to the off-light prohibition state.
[0075] As in the example above, when train 2 is traveling in accordance with the movement authorization, it will occupy the approach section IIIG of route X3->S and the first section 2-4DG within route X3->S.
[0076] When train 2 occupies the approach section and the first section 2-4DG, the computer interlocking system at station A can maintain the starting signal X3 in the off-light permission state. After receiving information from the radio block center system indicating that train 2 is crossing the starting signal X3, the computer interlocking system at station A can determine whether train 2 has crossed the starting signal X3 based on real-time data. If the real-time data indicates that train 2 has crossed the starting signal X3, the system will change the starting signal X3 from the off-light permission state to the off-light prohibition state. If the real-time data indicates that train 2 has not crossed the starting signal X3, it indicates that the information from the radio block center system is incorrect, and the starting signal X3 can be kept in the off-light permission state to avoid interfering with the driver of train 2.
[0077] In one embodiment, the method provided in this application further includes:
[0078] When the starting signal is in the off-light permission state, it continuously checks whether the section is in the departure direction, whether there are no hidden cars in the section, whether the route meets the interlocking route check conditions, and whether the communication between the computer interlocking system and the radio block center is interrupted. If the section is not in the departure direction, there are hidden cars in the section, the route does not meet the interlocking route check conditions, or the communication between the computer interlocking system and the radio block center is interrupted, then the starting signal is set to the off-light prohibition state.
[0079] This embodiment is a supplement to the visual authorization of train route processing in the computer interlocking system of the departure station.
[0080] When the starting signal of the visually authorized train route remains open, the departure station's computer interlocking system can continuously monitor it:
[0081] (1) Whether the section is in the direction of departure;
[0082] (2) Are there any hidden cars in the section?
[0083] (3) Whether the route meets the interlocking route inspection conditions (such as encroachment on the restricted section, turnout or protective turnout missing).
[0084] (4) Whether the communication between the computer interlocking system and the wireless block center is interrupted.
[0085] The computer interlocking system at the departure station can immediately shut down the starting signal and enter a no-lights-out state when any of the following conditions are met: the section is not in the departure direction, there is a hidden car in the section, the route does not meet the interlocking route inspection conditions, and the communication between the computer interlocking system and the radio block center is interrupted.
[0086] In one embodiment, after setting the starting signal to the off-light prohibition state, the method provided in this application further includes:
[0087] In response to the signal from the station operator allowing the restart operation, check whether the section is in the departure direction, whether there are no hidden cars in the section, and whether the route meets other check conditions in the fixed block route opening conditions; if it is found that the section is in the departure direction, there are no hidden cars in the section, and the route meets other check conditions in the fixed block route opening conditions, then reset the starting signal to the off-light permission state.
[0088] After the starting signal is closed due to a malfunction, the station operator can determine whether to allow the starting signal to be reopened based on the actual situation. If the station operator allows the starting signal to be reopened, the corresponding operation can be performed, which can be called the signal reopening permission operation.
[0089] In response to a signal permitting a restart, the departure station's computer interlocking system can check:
[0090] (1) Whether the section is in the direction of departure;
[0091] (2) Are there any hidden cars in the section?
[0092] (3) Whether the route meets the other inspection conditions in the fixed block route opening conditions.
[0093] If all the above checks pass—that is, the section is in the departure direction, there are no hidden cars in the section, and the route meets other check conditions for opening a fixed block route—the departure station's computer interlocking system can reopen the signal of the originating signal and reset it to the off-light, permitted state. It is understood that the above checks comply with the technical conditions for railway station computer interlocking.
[0094] After a visually authorized train's route is locked or signal is opened, the procedures for route cancellation, manual unlocking, and fault unlocking are the same as those for fixed block routes.
[0095] To better understand the above method, the following details an application example of the visual authorization train route processing method of this application. The system architecture of this application example includes:
[0096] Ground equipment: Computer Based Interlocking (CBI) system and radio block center system, etc.
[0097] Onboard equipment: mainly includes the onboard ATP (Automatic Train Protection) subsystem.
[0098] Data transmission equipment: ensures real-time communication between ground equipment and vehicle-mounted equipment.
[0099] This application example provides a processing flow for visually authorized train routes in a computer interlocking system, which involves aspects one through four.
[0100] Firstly, the prerequisites for the computer interlocking system at Station A to process visually authorized train routes are:
[0101] (1) The communication between the computer interlocking system of the departure station and the wireless block center system is normal. The computer interlocking system of the departure station can receive information from the wireless block center system, including the approaching train type information and cross pressure information in units of signal.
[0102] (2) The radio block center and the train communicate normally. Based on the interaction information, the radio block center determines that the train is a visually authorized train.
[0103] (3) The computer interlocking system of the departure station and the computer interlocking system of the arrival station communicate normally.
[0104] Secondly, the process of visually authorizing train routes from processing to signal clearance:
[0105] (1) After receiving the information from the wireless block center system that a visually authorized train is approaching the starting signal of the route, the computer interlocking system at the departure station sets the starting signal to the off-light prohibition state.
[0106] (2) From the time the operation is completed to the route locking, the computer interlocking system at the departure station checks the route of the visually authorized train according to the single-train route locking conditions. Once the route of the visually authorized train meets the single-train route locking conditions, the route of the visually authorized train is locked.
[0107] (3) Route signal open: The computer interlocking system of the departure station determines that the section is the departure direction, and receives the information that there are no hidden cars in the section sent by the wireless block center system. The route meets the fixed block route open conditions except for the section direction check conditions and the section clearing check conditions. This check follows the railway station computer interlocking technical conditions. The route signal is open, and the starting signal is set to the off-light permission state.
[0108] Thirdly, visual authorization of train route signal control:
[0109] (1) Normal closure of route signal: When a visually authorized train crosses the starting signal and simultaneously occupies the approach section and the first section within the route, the computer interlocking system of the departure station receives the information about the visually authorized train crossing the starting signal from the wireless block center system and then normally closes the signal of the starting signal.
[0110] (2) Route signal failure closure: The computer interlocking system of the departure station can continuously check whether the section is the departure direction, whether there is a hidden car in the section, whether the route meets the interlocking route check conditions (such as encroachment section occupancy, turnout or protective turnout malfunction), and whether the communication between the computer interlocking system and the wireless block center is interrupted; if the section is the receiving direction, there is a hidden car in the section, the route does not meet the interlocking route check conditions, or the communication between the computer interlocking system and the wireless block center is interrupted, the computer interlocking system of the departure station can control the starting signal to immediately fail and enter the light-off prohibition state.
[0111] (3) Reopening of route signal: After the starting signal is closed due to a fault, in response to the signal of the station operator allowing the reopening operation, the station computer interlocking system can determine whether to reopen the signal; when determining whether to reopen the signal, the station computer interlocking system needs to check whether the section is the departure direction, whether there are no hidden cars in the section, and whether the route meets other check conditions in the fixed block route opening conditions; if all the above checks are passed, the station computer interlocking system can reopen the signal of the starting signal and reset the starting signal to the off-light permission state.
[0112] Fourthly, visually authorizing the unlocking of train routes:
[0113] (1) Normal unlocking: After the starting signal of the route is closed normally, as the visually authorized train runs, the section meets the "three-point check" conditions, and the section within the route is unlocked in sections until the route is unlocked; if the "three-point check" conditions are not met due to limitations, "two-point check" can also be used.
[0114] (2) Other unlocking: The handling methods for route cancellation, manual unlocking and fault unlocking are the same as those for fixed block routes.
[0115] This application example adds the processing of visually authorized train routes to the traditional computer interlocking train route processing function. It is applicable to visually authorized trains that use the radio block center system for movement authorization. This visually authorized train route can allow only a single train to run on the route.
[0116] The opening conditions for the starting signal of a visually authorized train route differ from those for a single-train route. While a single-train route requires checking if the section is clear, a visually authorized train route only requires checking if there are any hidden cars in the section. Other inspection conditions remain the same. This application example also includes protective measures for this visually authorized train route, improving station throughput capacity while ensuring safety. This application example provides a computer interlocking visually authorized train route solution suitable for virtual train formation systems, and is one of the interlocking applications in the heavy-haul virtual train formation operation control system.

Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.
