Description

Technical Field

[0001] This invention belongs to the field of train control technology, and specifically relates to the computer interlocking system for the 64D section, the departure method, and the signal recognition method. Background Technology

[0002] In the operation of national and local railways, 64D semi-automatic block signaling is a commonly used technical method, such as... Figure 1 As shown, when the section between stations A and B uses the 64D semi-automatic block signaling system, the section is divided into three parts: AJG, the section without track circuits, and BJG. Only one train is allowed to run in the section at a time. The process for setting up block signaling is as follows:

[0003] (1) When station A needs to send a train to station B, the duty officer at station A shall first process the departure request and press the block button.

[0004] (2) After receiving the processing request from station A, station B agrees to station A's departure, presses the block button, and establishes a block;

[0005] (3) After the block is closed, Station A will handle the departure route, check that the block conditions are met, open the departure signal, and the starting signal will light the green light.

[0006] (4) The train departs and enters the section. The block conditions of the section are no longer met. Station B is notified to depart.

[0007] (5) After the train departs, Station B will arrange the receiving route and bring the train into the station;

[0008] (6) After the train enters the station, the staff at station B confirms that the train has arrived completely and presses the restoration button. Station B then sends the block restoration information to station A, and the section is restored.

[0009] During the above-mentioned train operation, only one train is allowed to run at the same time in the section. After step (3), the section blocking condition is no longer met, and station A can no longer process train departures to the section along the departure route.

[0010] However, the existing 64D semi-automatic block signaling is only applicable to the operation of a single train between two stations, and is not applicable to continuous departures between two stations. Summary of the Invention

[0011] To address at least one of the problems in the background art, the present invention proposes a computer interlocking system for the 64D section, a departure method, and a signal recognition method.

[0012] To achieve the above objectives, the present invention adopts the following technical solution:

[0013] A computer interlocking system for 64D intervals, comprising:

[0014] Adjacent stations, the sections between the adjacent stations are sequentially designated as a first approach track, a section track, and a second approach track, used to enable continuous train departures between adjacent stations;

[0015] Communication trains are used to continuously depart between adjacent stations and are equipped with an automatic train protection system.

[0016] The train automatic protection system transmits real-time information on the train's location and speed.

[0017] The interlocking center, located on the ground, communicates with the ground control center and is used to issue control commands for continuous train departures;

[0018] The ground control center is located on the ground and is connected in communication with the train automatic protection system.

[0019] Preferably, the station is equipped with a signal.

[0020] A train departure method for the aforementioned computer interlocking system for section 64D, including a switchable axle counting usage mode and axle counting deactivation mode;

[0021] In the axle counting mode, multiple communication trains are allowed to run between adjacent stations;

[0022] In the axle counting shutdown mode, only one communication train or ordinary train is allowed to run between adjacent stations, and the ordinary train is not equipped with an automatic train protection system.

[0023] Preferably, the axle counting usage mode includes the following steps:

[0024] A block system is established between adjacent stations, with one station designated as the departure station and the departure route signal open;

[0025] The communication train departs and enters the first or second approach track, with the adjacent stations in an unblocked state, and notifies the receiving station that the communication train has departed.

[0026] After the communication train departs, the receiving station arranges the receiving route and connects the communication train to the receiving station. After the communication train enters the receiving station, it is determined whether the automatic restoration condition of the section is triggered. If it is triggered, the block between adjacent stations is automatically restored. If it is not triggered, the departure station has already departed again, the departure route signal is open, or the communication train has re-entered the section and occupied the first approach track, the section track, or the second approach track.

[0027] Preferably, the automatic interval restoration condition is as follows: the communication train enters the receiving station and the first approach track, the interval track, and the second approach track are empty, while the departure station has not sent departure information to the receiving station.

[0028] Preferably, a block system is established between adjacent stations, with one station serving as the departure station and the departure route signal open, comprising the following steps:

[0029] Check if the first approach track, the second approach track, and the interval track are free;

[0030] If the station is free, block requests between two adjacent stations are processed through the interlocking center to establish a block system.

[0031] The interlocking center selects one station as the departure station and the other as the receiving station, opens the departure route signal, and turns off the signal lights.

[0032] Preferably, the communication train departs and enters the first or second approach track, with adjacent stations in an unblocked state, and notifies the receiving station that the communication train has departed, including the following steps:

[0033] The interlocking center sends route information and permission for communication trains to pass to the ground control center;

[0034] The ground control center sends a mobile authorization to the train's automatic protection system.

[0035] The Automatic Train Protection System (ATPS) controls the train to depart and enter the first or second approach track based on the movement authorization, ensuring that the adjacent stations are not blocked, and notifies the receiving station that the train has departed.

[0036] Preferably, the train departs again from the departure station, and the departure route signal is open, including the following steps:

[0037] The interlocking center controls the departure station to have continuous departure information in the departure direction and the receiving station to have continuous departure information in the receiving direction, thus satisfying the continuous departure condition.

[0038] The train departs via the interlocking center, which issues a departure route open signal, allowing the train to enter the first or second approach track, and the signal lights are turned off.

[0039] Preferably, in the axle counting mode, continuous departures include the following conditions:

[0040] The interlocking center issues a message indicating that the train can depart.

[0041] At the interlocking center, continuous departure information for both the departure and receiving directions of the trains at the departure station and the receiving station is activated.

[0042] Preferably, the axle counting shutdown mode includes the following steps:

[0043] Establish block systems between adjacent stations;

[0044] After the block is closed, one of the stations will set a departure route, open the departure signal, and the signal will be green.

[0045] When a communication train or a regular train departs and enters the approach track, and the adjacent station is notified that the communication train or regular train has departed;

[0046] After a communication train or a regular train departs, the receiving station will arrange the receiving route until the communication train or regular train is brought into the station.

[0047] After a communication train or a regular train enters a station, the receiving station sends a block restoration message to the departing station, so that the block restoration is completed at the adjacent station.

[0048] Preferably, in the axle counting shutdown mode, departure includes the following conditions:

[0049] The interlocking center issued a message that the train could depart.

[0050] A signal recognition method for use in the aforementioned vehicle departure method includes the following steps:

[0051] In axle counting mode, the signal status is determined. If the signal is red or off and communication trains are not allowed to pass, then departure is not allowed. If the signal is off and communication trains are allowed to pass, then the train departure route is received from the interlocking center through the automatic train protection system.

[0052] In the axle counting shutdown mode, the signal status is checked. If the signal is red, departure is not allowed; if the signal is green, departure is allowed.

[0053] The beneficial effects of this invention are:

[0054] 1. The computer interlocking system of the present invention for the 64D section adopts an interlocking center, a ground control center and onboard ATP, so that information can be exchanged between the two stations during the train operation, thereby realizing continuous departure between the two stations;

[0055] 2. The train departure method of the present invention can switch between axle counting usage mode and axle counting discontinuation mode as needed. The axle counting usage mode is suitable for continuous departure, while the axle counting discontinuation mode is suitable for single train operation between two stations.

[0056] 3. The identification method of the present invention can formulate different control processes according to communication trains and ordinary trains respectively. Communication trains are launched through onboard ATP, while ordinary trains are launched through green lights. This identification method is further adapted to communication trains and improves the working efficiency of computer interlocking to the 64D section system.

[0057] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures pointed out in the description and the drawings. Attached Figure Description

Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0060] Figure 2 The computer interlocking system structure diagram of the present invention to section 64D is shown;

[0061] Figure 3 A flowchart of the departure method for the axle counting usage mode of the present invention is shown;

[0062] Figure 4 A flowchart of the departure method for the axle counting shutdown mode of the present invention is shown. Detailed Implementation

[0063] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0064] A computer interlocking system for 64D intervals, such as Figure 2As shown, the system includes adjacent stations A and B, a communication train, an interlocking center (CBI), a ground control center (GCC), and an automatic train protection system (ATP). The section between adjacent stations A and B is divided into a first approach track, a section track, and a second approach track, enabling continuous train departures between adjacent stations. During departures, the communication train can continuously depart between the two stations. The communication train has an integrated automatic protection system that collects the train's speed and position information in real time, transmits it to the ground control center, and then returns it to the interlocking center. The interlocking center is located on the ground and communicates with the ground control center to issue control commands for continuous departures, including departure information. The ground control center is also located on the ground and communicates with the automatic train protection system.

[0065] Furthermore, signals are installed at stations A and B. During operation, the train driver can select the working mode based on the status of the signals.

[0066] It needs to be said that, in Figure 1 In the section between stations A and B, an axle counting device is added to the corresponding track to check the availability of the previously un-tracked circuit section (named Q1G). The section is divided into three parts: the first approach track (AJG), the section track (Q1G), and the second approach track (BJG). AJG and Q1G are under the jurisdiction of station A's computer interlocking system, while BJG is under the jurisdiction of station B's computer interlocking system. Furthermore... Figure 1 SI, SII, SIII, XI, XII and XIII all represent signals, while XA and SB represent station boundaries.

[0067] In addition, Figure 1 In the system, the interlocking center has added a section direction function, which includes three states: no direction, departure direction, and receiving direction. Normally, the section direction is no direction. After station A requests a block signal and station B approves it, station A establishes a departure route into the section. Once the block conditions are met, the signal is opened, and station A becomes the departure direction, while station B becomes the receiving direction. During train departure and while the train is running in the section, the section direction remains unchanged for both stations. After station B establishes a receiving route, the train fully enters station B, and the block signal is restored, the section direction for both stations returns to no direction.

[0068] In addition, Figure 1In the interlocking system, continuous departure information has been added, divided into two types: continuous departure information in the departure direction and continuous departure information in the receiving direction. Normally, continuous departure information is inactive. When the section direction at station A is the receiving direction, the continuous departure information for the receiving direction at station A is activated if AJG is idle or occupied by a communication car, and Q1G is also idle or occupied by a communication car. When the section direction at station A is the departure direction, the continuous departure information for the departure direction at station A is activated if AJG is idle or occupied by a communication car, and Q1G is also idle or occupied by a communication car. When the section direction at station B is the receiving direction, the continuous departure information for the receiving direction at station B is activated if BJG is idle or occupied by a communication car. When the section direction at station B is the departure direction, the continuous departure information for the departure direction at station B is activated if BJG is idle or occupied by a communication car.

[0069] In addition, the Interlocking Center (CBI) communicates with the Ground Control Center (GCC) to obtain information on train operation within the section, including the occupancy of both communication and non-communication trains. When a communication train is operating within the section, the following communication train can safely enter the section via the Interlocking Center-Ground Control Center-Onboard ATP control system, and multiple trains can operate simultaneously in the same direction within the section. When a non-communication train is operating within the section, or when the following train is also a non-communication train, multiple trains cannot operate safely together within the section; only one train can operate at a time within the section.

[0070] In addition, to ensure that the connecting trains are controlled through the interlocking-GCC-onboard ATP system, that is, to ensure that the connecting trains operate as communication trains, the starting signal of the departure route for the connecting trains is turned off (when departing into the section in the existing mode, the starting signal is green), the interlocking sends the route information and the information that the communication train is allowed to pass to the GCC, the GCC generates a MA and sends it to the ATP, and the ATP controls the train to enter the section based on the MA.

[0071] In addition, the above system allows adjacent stations to communicate through the interlocking center, transmitting departure route information and continuous departure information of the station to the interlocking center of the neighboring station.

[0072] In addition, based on the interlocking center's existing checks that the train enters the receiving station and that sections AJG, Q1G, and BJG are all clear, a new check is added: if there is no departure route at the adjacent station, the section will automatically restore after the train arrives at station B. This additional check for no departure route at the adjacent station is to protect the following train from being in the section before it enters the section, even if the preceding train has fully entered the receiving station and triggered the existing automatic block restoration condition: the trains enter the receiving station sequentially and the section is clear (AJG, Q1G, and BJG are all clear), thus ensuring the safe operation of the following train within the section.

[0073] The following is combined with Figure 3 and Figure 4The method for dispatching vehicles according to the present invention will be described as follows:

[0074] A train departure method applicable to the aforementioned computer interlocking system for section 64D includes a switchable axle counting usage mode and an axle counting deactivation mode. In the axle counting usage mode, multiple communication trains are allowed to run between adjacent stations; in the axle counting deactivation mode, only one communication train or ordinary train is allowed to run between adjacent stations, and the ordinary train is not equipped with an automatic train protection system.

[0075] It should be noted that, in Figure 1 In this context, it primarily corresponds to the axle counting mode, which is applicable to communication trains. In the axle counting deactivation mode, both communication trains and regular trains can operate.

[0076] Furthermore, such as Figure 3 As shown, the axle counting usage mode includes the following steps:

[0077] S1: A block signal is established between adjacent stations, with one station serving as the departure station and the departure route signal being open; S2: The communication train departs and enters the first or second approach track, the adjacent stations are in an unblocked state, and the receiving station is notified that the communication train has departed; S3: After the communication train departs, the receiving station establishes a receiving route to connect the communication train to the receiving station. After the communication train enters the receiving station, it is determined whether the automatic restoration condition of the section is triggered. If it is triggered, the block signal between adjacent stations is automatically restored.

[0078] Furthermore, the automatic interval restoration condition is as follows: the communication train enters the receiving station and the first approach track, the interval track, and the second approach track are empty, while the departure station has not sent departure information to the receiving station.

[0079] It should be noted that the interlocking center will issue departure information, which means that the train is about to depart from the departure station or that the train is about to enter the first or second approach track from the station track.

[0080] Further, step S1 includes the following steps:

[0081] S101: Detect whether the first approach track, the second approach track, and the section track are free; S102: If free, process the block request between the two adjacent stations through the interlocking center to establish a block; S103: Select one station as the departure station and the other as the receiving station through the interlocking center, open the departure route signal, and turn off the signal lights at the same time.

[0082] Further, step S2 includes the following steps:

[0083] S201: The interlocking center sends route information and permission for the communication train to pass to the ground control center; S202: The ground control center generates a movement authorization and sends it to the automatic train protection system; S203: The automatic train protection system controls the communication train to depart and enter the first or second approach track based on the movement authorization, with adjacent stations in an unblocked state, and notifies the receiving station that the communication train has departed.

[0084] It should be noted that in the axle counting mode, continuous departure includes two conditions: (1) the interlocking center issues a departure information, which is an existing check block condition; (2) at the interlocking center, the continuous departure information of the departure station in the departure direction is activated and the continuous departure information of the receiving station in the receiving direction is activated.

[0085] Furthermore, in S3, the departure station departs again, and the departure route signal is opened, including the following steps: S301: The interlocking center controls the departure station's continuous departure information in the departure direction to be active and the receiving station's continuous departure information in the receiving direction to be active, thus satisfying the continuous departure condition; S302: The interlocking center processes the departure route, issues the departure route open signal, and allows the communication train to enter the first approach track or the second approach track again, and the signal lights are turned off.

[0086] The following is combined with Figure 1 Following the steps S1 to S3, with station A designated as the departure station (referred to as Station A) and station B as the receiving station (referred to as Station B), the specific implementation of steps S1 to S3 is as follows: The process of handling block traffic is as follows:

[0087] 1) When neither station has applied for block signaling and station A needs to send a train to station B, station A applies for a departure route. If the sections AJG, Q1G, and BJG are all free, the departure route is established. If the section of station A is free (AJG, Q1G, and BJG are all free), station A automatically sends a block request message. After receiving the block request, station B checks that the section is free (AJG, Q1G, and BJG are all free) and automatically sends a block approval message to establish the block. If the block conditions are met, the departure route signal is opened and the starting signal is turned off.

[0088] 2) After the departure signal is opened at Station A, the direction of the section at Station A changes from no direction to departure direction, and the direction of the section at Station B changes from no direction to receiving direction.

[0089] 3) Station A becomes the departure direction, and both AJG and section track Q1G under the jurisdiction of Station A are idle. The continuous departure information for the departure direction changes from inactive to active. Station B becomes the receiving direction, and BJG under the jurisdiction of Station B is idle. The continuous departure information for the receiving direction changes from inactive to active. Station B transmits the activation information of the continuous departure information for the receiving direction to the departure station A through the newly added network.

[0090] 4) The interlocking center sends the route information and permission for the communication train to pass to the GCC. The GCC forms a MA and sends it to the ATP. The ATP controls the communication train (this train is called the forward train) to depart and enter the section based on the MA (Movement Authorization). The section blocking conditions become unsatisfactory, and the B station is notified to depart.

[0091] 5) After the continuous departure information of the train departing from station A is activated from inactive, the communication train remains activated when running in the section; after the continuous departure information of the train receiving from station B is activated, the communication train remains activated when running in the section.

[0092] 6) When station A needs to dispatch trains continuously, a dispatch route is processed. If the blocking conditions of the dispatch route section are no longer met, the newly added continuous dispatch information is checked. If the continuous dispatch information in the dispatch direction of station A is active and the continuous dispatch information in the receiving direction of station B is active, the newly added continuous dispatch conditions are met. The dispatch route signal is opened, and the train (this train is called the connecting train) is allowed to enter the section again. The signal at the beginning of the route is turned off.

[0093] The following section describes two scenarios of continuous departures, based on two different automatic interval restoration conditions:

[0094] The first scenario for continuous train departures:

[0095] (1) The interlocking sends the route information and the permission for communication trains to pass to the GCC. The GCC forms the MA and sends it to the ATP. The ATP controls the following trains to enter the section after departure based on the MA. Station B handles the receiving route and connects all trains in the section to the station.

[0096] (2) Station B computer interlocking checks new trigger section automatic restoration conditions: the train enters the receiving station and sections AJG, Q1G and BJG are all free. At the same time, it checks that there are no departure route conditions at Station A (no departure information). At this time, the receiving station B automatically sends the block restoration information to Station A, and the block is automatically restored.

[0097] (3) After the block section is restored, the direction of the section between stations A and B is restored to no direction, and the continuous departure information of stations A and B becomes inactive.

[0098] The second scenario for continuous train departures:

[0099] (1) The interlocking sends the route information and the permission for the train to pass to the GCC. The GCC forms an MA and sends it to the ATP. The ATP controls the communication of the connecting train based on the MA. When the train is moving towards the section within the departure station but has not yet entered the section, the receiving station B arranges a receiving route for the preceding train. The preceding train completely enters station B. Station B checks and finds that the new automatic restoration conditions for the section are not met. At this time, the train enters the receiving station and the sections AJG, Q1G and BJG are all empty, but there is a departure route at the adjacent station. The receiving station B does not send the block restoration information to station A.

[0100] (2) When the connecting train enters the section, the receiving station B will arrange the receiving route for the connecting train. The connecting train will fully enter station B. Station B will check that the new automatic section restoration conditions are met: the train enters the receiving station and sections AJG, Q1G and BJG are all free, and there is no departure route (no departure information) at the adjacent station. At this time, the receiving station B will automatically send the block restoration information to station A, and the block will be automatically restored.

[0101] (3) After the block section is restored, the direction of the section between stations A and B is restored to no direction, and the continuous departure information of stations A and B becomes inactive.

[0102] Furthermore, such as Figure 3 As shown, the axle counting shutdown mode includes the following steps:

[0103] Q1: Establish a block signal between adjacent stations; Q2: After the block signal is established, one station establishes a departure route, opens the departure signal, and the signal is green; Q3: When a communication train or regular train departs and enters the approach track, the adjacent station is in an unblocked state and notifies the other station that the communication train or regular train has departed; Q4: After the communication train or regular train departs, the receiving station establishes a receiving route until the communication train or regular train enters the station; Q5: After the communication train or regular train enters the station, the train's arrival is confirmed manually, and the restoration button is pressed manually. The receiving station sends a block restoration message to the departing station, restoring the block signal at the adjacent station.

[0104] It should be noted that, Figure 4 The steps shown are the same as those in the traditional ordinary train operation mode, and the system of the present invention can switch between the two modes. Moreover, in the axle counting shutdown mode, the departure condition includes: the interlocking center issuing a departure permission message.

[0105] All of the above departure methods require the use of traffic signals. These signals are primarily used to indicate whether departure is permitted. Below, we introduce a signal recognition method for one of the aforementioned departure methods, including the following situations:

[0106] For example, in axle counting mode, the system checks the signal status. If the signal is red or off, disallowing communication between trains, departure is not permitted. If the signal is off and communication between trains is permitted, the system receives departure information and departure route from the interlocking center via the automatic train protection system. Similarly, in axle counting disabled mode, the system checks the signal status. If the signal is red, departure is not permitted; if the signal is green, departure is permitted.

[0107] It should be noted that, under normal circumstances, when the axle counting mode is in use, the communication train needs to depart continuously, so it directly determines whether it can depart through the ATP (Automatic Train Protection) system, without needing to use a green signal. However, in the axle counting mode, there is no ATP or the ATP is not working, so a green signal is needed.

[0108] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
