Description

Technical Field

[0001] The present invention relates to the field of rail transit communication technology, and in particular to a moving block departure method and a moving block control system. Background Art

[0002] Moving block refers to a communication-based block mode in which the following train automatically sets the running speed according to the distance between it and the preceding train and the route conditions. In this block system, the interval between trains is not fixed. As long as the braking distance of the following train is guaranteed and the appropriate protective distance is added, the traffic density can be greatly improved. It is widely used in high-density urban rail transit systems.

[0003] Currently, in the CTCS (ChinaTrain Control System) system, all calculations of driving permits are provided by ground equipment. Specifically, in the CTCS-2 train control system, the movement authorization of the train is completed by the track circuit, and the on-board equipment of the train completes the calculation of the train operation control by receiving the low-frequency code of the track circuit in combination with the ground transponder information; in the CTCS-3 train control system, the movement authorization of the train is calculated by the RBC (Radio Block Center), that is, the wireless block center. RBC provides line data and movement authorization information to the on-board equipment of the train, and the on-board equipment calculates the stopping point through the movement authorization provided by RBC; in the CTCS-N train control system (new train control system), the position of the leading car is calculated by RBC, and the movement authorization to the rear of the leading car is sent to the following car, thereby realizing movement blocking in the station. The specific implementation method is as follows: Figure 1 shown.

[0004] However, as the railway's demand for operational efficiency continues to increase, the station's ability to receive and dispatch trains has also been challenged, especially in the field of freight railways. Generally speaking, in the field of urban rail transit, the distance between the train stop in the track and the exit signal is generally less than 10 meters; while in freight railways, the distance between the train stop in the track and the exit signal is generally 50 meters, and because freight trains are more difficult to start, it takes a long time from the start of the train to the train reaching the exit signal. Using the existing mobile block departure method will result in a long departure interval between the two trains, and the station's efficiency in receiving and dispatching trains is low, which cannot meet the railway's demand for increasing operational efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide a mobile block departure method and a mobile block control system, which are used to address the problems of long departure intervals between two trains and low efficiency in station train reception and dispatching. In the case of mobile block, according to the running characteristics of the trains in the station and the layout of the station equipment, when it is judged that the rear end of the leading train is about to pass the signal, a departure reminder or departure command is issued to the subsequent train in advance, thereby shortening the train tracking time and improving the station's train reception and dispatching efficiency.

[0045] The following is a further detailed description of a mobile block departure method and a mobile block control system proposed by the present invention in combination with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention. In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, please refer to the accompanying drawings. It should be noted that the structure, proportion, size, etc. illustrated in the drawings of this specification are only used to match the content disclosed in the specification, so that people familiar with this technology can understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no technical substantive significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effect that the present invention can produce and the purpose that can be achieved, should still fall within the scope of the technical content disclosed by the present invention.

[0046] As described in the background technology, in the existing CTCS-N level train control system, the position of the leading train is calculated by the RBC system, and according to the position of the leading train, a movement authorization to the rear of the leading train is sent to the following train, thereby realizing moving block in the station. The RBC system, i.e., the radio block center, can issue train operation permission and train control information to all trains in the jurisdiction according to the train position, operation, line conditions, dispatching commands and route status. For example, it can command the train operation in real time by calculating the train position and sending movement authorization to the train.

[0047] Specifically, Figure 1 As shown in the figure, the station is equipped with an entry signal S and an entry signal X at both ends to protect the station, indicate whether the train can enter the station from the section, interlock with the hostile approach, and ensure the safety and reliability of the approach after the signal is opened. The entry signal S and the entry signal X can be set at a distance of not less than 50 meters from the station entry turnout tip (reverse turnout) or the warning mark (forward turnout).

[0048] There are multiple tracks in parallel in the station, and exit signals are set on both sides of each track. The exit signals are used to protect the section and serve as proof that the train occupies the section, indicating whether the train can leave the station for the section. Specifically, exit signals S1, SII, S3 and S4 corresponding to the entry signal S are set on the side of each track away from the entry signal S; exit signals X1, XII, X3 and X4 corresponding to the entry signal X are set on the side of each track away from the entry signal X. Train 1, i.e., the leading train, is parked between the exit signal S1 and the exit signal X1; train 2, i.e., the following train, is parked between the exit signal SII and the exit signal XII; the locomotives of the leading train and the following train keep a certain distance from the exit signal X1 and the exit signal XII in front, respectively.

[0049] A through signal D4 is provided in front of the intersection of the track with the exit signal X1 and the track with the exit signal XII. Figure 1 As shown in the first figure in FIG, in order to realize moving block in the station, a driving permission is first sent to the leading train so that the leading train can pass the exit signal X1. Further, the leading train moves forward and passes the passing signal D4, as shown in FIG. Figure 1 As shown in the second and third figures in the figure, after the leading train passes the signal D4, a driving permit is sent to the following train so that the following train can pass the exit signal XII.

[0050] like Figure 2 As shown, taking a station existing in reality as an example. The traction constant of the preceding train and the following train is 5000t, and the length of the preceding train and the following train is 600 meters; the distance between the front of the preceding train and the exit signal X1 is 50 meters; the distance between the front of the following train and the signal XII is 50 meters; all turnouts are No. 12 turnouts, and the lateral speed limit is 45km; the running speed of the train entering the section (the tail of the train passes the exit signal S) is 80km / h.

[0051] According to the principle of moving block, when the rear of the leading train passes the passing signal D4, the running distance of the leading train is: the distance between the leading train and the exit signal X1 + the distance from the exit signal X1 to the passing signal D4 + the length of the leading train, that is, 50 meters + 80 meters + 600 meters = 730 meters. According to the simulation calculation of the operation of the leading train, the running time of the leading train from starting to the rear of the train passing the passing signal D4 is 152 seconds.

[0052] When the rear end of the preceding train passes the signal D4, the additional time for the following train to depart is as shown in Table 1.

[0053]

[0054] Table 1

[0055] In summary, in the prior art, under moving block conditions, the departure interval between the preceding train and the following train is: 152 seconds + 25 seconds = 177 seconds.

[0056] In order to solve the problem of long departure interval in the prior art, the first aspect of this embodiment provides a moving block departure method, including: controlling the departure of the preceding train; when it is determined that the rear of the preceding train is about to pass the signal D4, issuing a departure reminder or departure command to the following train. Figure 3 and Figure 4 As shown, when it is determined that the rear end of the preceding train is about to pass the signal D4, a departure reminder is issued to the following train in advance, so that the following train departs in advance to shorten the departure interval.

[0057] In addition, in order to ensure that there is no safety risk in the early departure of the subsequent train, Figure 4 As shown by the dotted line in . Before issuing a departure reminder or a departure command to the following train, the RBC system on the ground can grant the following train a movement authorization from the front of the following train to the exit signal XII in front of the front of the train. Since the RBC system grants the movement authorization, the following train will not rush through the exit signal XII before the permission signal is opened, which fully ensures the driving safety of the leading train and the following train.

[0058] like Figure 5 As shown, in order to determine whether the rear end of the leading train is about to pass the through signal, a preset time can be set in advance, and the position of the leading train and the remaining time for the rear end of the leading train to pass the through signal D4 can be calculated by the RBC system. When the remaining time for the rear end of the leading train to pass the through signal D4 is less than the preset time, it can be determined that the rear end of the leading train is about to pass the through signal D4.

[0059] Specifically, the preset time can be the time taken by the following train from starting to stopping in front of the exit signal XII in front of the train head. By simulating the operation of the following train, it can be obtained that the time taken by the following train from starting to stopping after running 50 meters forward is 40 seconds (i.e. the time taken by the following train from starting to stopping in front of the exit signal XII). That is, when the leading train is in operation, when the RBC system determines that the tail of the leading train has less than 40 seconds to cross the D4 signal, the departure prompt or departure command is sent to the following train in advance.

[0060] Alternatively, the preset time may be the additional time of the subsequent train, as shown in Table 1, and the additional time includes: the time from the tail of the preceding train passing through the signal D4 to the time when the CTC system obtains the free section; the time from the time when the CTC system issues a departure route for the exit signal XII in front of the head of the subsequent train to the time when the departure route is completed; and the vehicle-machine joint control time between the driver of the subsequent train and the station attendant. As shown in Table 1, the additional time is, for example, 25 seconds. That is, when the preceding train is in operation, when the RBC system determines that the tail of the preceding train has less than 25 seconds to pass the D4 signal, a departure prompt or departure command is sent to the subsequent train in advance.

[0061] Specifically, in order to issue the departure reminder or the departure command to the subsequent train, the driving state of the subsequent train may be further judged. When the subsequent train is driven by a driver, the departure reminder is issued to the subsequent train, and the driver of the subsequent train performs the departure operation according to the departure reminder. Alternatively, when the subsequent train is automatically driven, the departure command is issued to the subsequent train, and the departure operation is performed through the automatic driving system of the subsequent train.

[0062] The mobile block departure method provided in this embodiment is adopted to calculate the time for the tail of the leading train to cross the first section in front of the departure track of the subsequent train according to the operation status of the leading train (taking into account the position and speed of the leading train), and send a departure prompt to the subsequent train in advance to shorten the departure interval between the leading train and the subsequent train. If an abnormal situation occurs, such as the leading train stops in the section ahead or the track circuit in the section ahead fails (the exit signal XII cannot be opened, and the movement authorization of the subsequent train cannot be extended), since the RBC system gives the subsequent train movement authorization, the subsequent train will not rush forward when the exit signal XII does not open the permission signal, thereby ensuring the safety of the train. In summary, this scheme can shorten the departure interval between the leading train and the subsequent train by at least 25 seconds in the case of existing stations.

[0063] It is understandable that if Figure 2 As shown, in addition to the passing signal D4 provided in front of the intersection of the tracks where the preceding train and the following train stop, passing signals may also be provided in front of the intersections of other tracks, such as passing signals D1, D2, D3 and D5.

[0064] Although in the above method, the leading train stays at the track between the exit signal S1 and the exit signal X1, and the following train stays at the track between the exit signal SII and the exit signal XII, and the passing signal D4 is used as the basis for judgment. However, the leading train and the following train can stay at any of the tracks, as long as they are in the same direction, and can use the passing signals D1, D2, D3, D4 and D5 or passing signals set at other locations as the basis for judgment as needed, and the present invention does not limit this. In addition, the same station can be equipped with multiple groups of the leading trains and the following trains at the same time, and the following train of the previous group can, for example, serve as the leading train of the next group, thereby further improving the station's efficiency in receiving and dispatching trains.

[0065] In order to realize the above-mentioned mobile block departure method, the second aspect of this embodiment provides a mobile block control system, including multiple tracks, exit signals, passing signals, CBI system, the CTC system and the RBC system. The CBI system is connected in communication with the exit signal and the passing signal; the CTC system is connected in communication with the CBI system; the RBC system is connected in communication with the preceding train, the following train, the CBI system and the CTC system. The settings of the tracks, exit signals and passing signals have been described in detail above and will not be repeated here.

[0066] The main functions of the CTC system include the control and execution of the train operation phase plan, which can transmit the train operation phase plan to the autonomous machine of each station to realize autonomous execution, for example, it can be used to handle the departure route of the exit signal. Figure 6 As shown, the CTC system can send the operation plan to the preceding train and the following train through TSRS (Temporary Speed ​​Restriction Server), and the onboard ATO (Automatic Train Operation) can display the operation plan to the driver through the onboard interface after receiving the operation plan.

[0067] Furthermore, the CTC system can first handle the departure route of the outbound signal X1 in front of the preceding train according to the operation plan. After the handling is successful, the CBI system, i.e., the computer interlocking system, which is used to control the outbound signal and the passing signal, can open the outbound signal X1 and send route status information to the RBC system.

[0068] like Figure 6 As shown, the RBC system can be used to control the departure of the leading train and send a movement authorization to the leading train through the exit signal X1. The onboard ATP (Automatic Train Protection) of the leading train can calculate the operation curve according to the movement authorization and send relevant information to the onboard ATO to realize the departure of the leading train. At the same time, the RBC system gives the following train a movement authorization from the locomotive of the following train to the exit signal XII.

[0069] The RBC system can also be used to send a departure prompt or departure command to the on-board ATP of the subsequent train when it is determined that the rear end of the leading train is about to pass the passing signal, thereby realizing the departure of the subsequent train.

[0070] Furthermore, the RBC system is also used to obtain the remaining time for the rear of the leading train to pass the passing signal through simulation calculation according to the real-time position of the leading train, and when the remaining time is less than the preset time, it is judged that the rear of the leading train will pass the passing signal. Specifically, when the preset time is the time taken for the following train to stop in front of the exit signal in front of the front of the train, the RBC system can obtain the preset time by simulating the operation of the following train. Alternatively, when the preset time is the additional time of the following train, the RBC system can obtain the preset time by accumulating the various contents of the additional time.

[0071] Furthermore, the RBC system is also used to determine the driving status of the subsequent train when issuing the departure reminder or the departure command. When it is determined that the subsequent train is driven by a driver, the RBC system issues the departure reminder to the subsequent train. When it is determined that the subsequent train is automatically driven, the RBC system issues the departure command to the subsequent train.

[0072] like Figure 6As shown, after the subsequent train departs, the RBC system can send the status (including position and speed) of the leading train to the CTC system. After the CTC system determines that the leading train has passed the passing signal D4, the exit signal XII can be opened through the CBI system, and the movement authorization extended to the passing signal D4 can be sent to the subsequent train through the RBC system.

[0073] The present invention can reduce the departure interval between the leading train and the following train by issuing a departure reminder or departure command to the following train in advance when it is judged that the rear end of the leading train is about to pass the signal, which is beneficial to shortening the train tracking time and improving the station's receiving and dispatching efficiency. Compared with the existing technology, it is a significant improvement.
