DESCRIPTION OF EMBODIMENTS

[0012] Further description of the technical solutions according to the embodiments of the present invention will be provided in conjunction with the accompanying drawings.

[0013] Aiming at the existing defects of the distributed control mode in the speed restriction control in the prior art, embodiments of the present invention deliver a solution, i.e., a new train control equipment: a temporary speed restriction server (TSRS), which adopts a control system based on a signal failure safety computer. It realizes centralized management of the train control speed restriction command of whole line for guaranteeing the safety of the train control speed restriction device, so as to ensure successful implementation of planned construction speed restriction.

[0014] FIG. 1 is a schematic diagram of the principle for realizing a speed restriction function for a CTCS-3 train control system according to the present invention. As shown in FIG. 1, the TSRS provided by the embodiment of the present invention obtains the temporary speed restriction command from a central dispatcher by connecting to a centralized traffic control system (CTC), so as to realize automatic distribution and centralized management of train control speed restriction command for each TCC and RBC within the scope of full line management and control without participation of each station attendant, and efficiently guarantee the consistency of speed restriction for C3 and C2.

[0015] FIG. 2 is a flow diagram of a method for sending a temporary speed restriction command in a C3 system method according to the embodiment of the present invention, as shown in FIG. 2, the method includes:

step 100, receiving, by a temporary speed restriction server TSRS, a temporary speed restriction command issued by a centralized traffic control system CTC, wherein the temporary speed restriction command at least includes a speed restriction value, a speed restriction zone starting point, a speed restriction zone end point, a line number, a dispatching command number and a station number;

[0016] The TSRS in this embodiment can be described as an example of C3 temporary speed restriction server. The temporary speed restriction command is uniformly set up by the central dispatcher on the CTC, and the train control speed restriction function need to be completed together by an ATP onboard device and a ground device (including ground devices such as CTC, TSRS, TCC, and RBC).

[0017] The CTC system proposes contents of the temporary speed restriction planning dispatching command, and then sends a temporary speed restriction command (TSR), where at least the following information are carried: the speed restriction value, the speed restriction zone starting point, the speed restriction zone ending point, the line number, the dispatching command number and the station number.

[0018] In this embodiment, the TSRS can also execute an executable check for the speed restriction value, the speed restriction zone starting point, the speed restriction zone ending point, the line number, the dispatching command number and the station number in the TSR signaling.

[0019] Step 101, automatically splitting, by the TSRS, the temporary speed restriction command for the related TCC and/or RBC according to the speed restriction zone starting point, the speed restriction zone end point, and jurisdiction of each train control center TCC and/or radio block center RBC on the track line corresponding to the line number;

[0020] After the TSRS receives the temporary speed restriction command issued by the CTC system, according to the speed restriction zone starting point, the speed restriction zone ending point, and related TCC and/or RBC jurisdiction it carried, automatically splits the temporary speed restriction command and distributes it to the related TCC and RBC for execution. The specific distribution rule includes:

if a TCC and/or RBC's jurisdiction covers the speed restriction zone starting point and the speed restriction zone end point, before field information of the speed restriction zone starting point and the speed restriction zone end point in the temporary speed restriction command sent, adding a coverage speed restriction sign used for indicating the speed restriction zone is located within the jurisdiction;

if a TCC and/or RBC's jurisdiction covers the speed restriction zone starting point but fails to cover the speed restriction zone end point, before the speed restriction zone starting point in the temporary speed restriction command sent, adding a first sign used to indicate the speed restriction zone is located within the jurisdiction, and before the field information of the speed restriction zone end point, adding a second sign used to indicate the speed restriction zone is located on the forward side of the jurisdiction;

if a TCC and/or RBC's jurisdiction does not cover the speed restriction zone starting point but covers the speed restriction zone end point, before the speed restriction zone starting point in the temporary speed restriction command sent, adding a third sign used to indicate the speed restriction zone is located on the reverse side of the jurisdiction, and before the field information of the speed restriction zone end point, adding a first sign used to indicate the speed restriction zone is located within the jurisdiction;

if a TCC and/or RBC's jurisdiction does not cover the speed restriction zone starting point or the speed restriction zone end point, before the speed restriction zone starting point in the temporary speed restriction command sent, adding a third sign used to indicate the speed restriction zone is located on the reverse side of the jurisdiction, and before the field information of the speed restriction zone end point, adding a second sign used to indicate the speed restriction zone is located on the forward side of the jurisdiction.

[0021] The TSRS resets the field information of the speed restriction zone starting point and the speed restriction zone end point in the temporary speed restriction command that are sent to a particular TCC and/or the RBC, realizing the distribution to TCC and/or RBC of the temporary speed restriction command.

[0022] Step 102, sending, by the TSRS, the corresponding temporary speed restriction command to the TCC and / or the RBC, and carrying a command identifier for identifying the temporary speed restriction command.

[0023] After resetting the temporary speed restriction command, the TSRS sends the corresponding temporary speed restriction command to the TCC and/or the RBC. In particular, the TCC system is responsible for controlling the active transponder to send the corresponding TSR information to a C2 vehicle; the RBC system is responsible for sending corresponding TSR information to the C3 train through GSM-R. After the train with an ATP onboard device receives TSR information, it controls the train to run according to the requirement of speed restriction.

[0024] In the sending method of the temporary speed restriction command provided by the embodiment, a TSRS receives a temporary speed restriction command issued by a CTC; the TSRS, according to the speed restriction zone starting point, the speed restriction zone end point, and speed restriction jurisdiction of each TCC and/or RBC on the railway line corresponding to the line number, automatically splits the temporary speed restriction command, then it sends the corresponding temporary speed restriction command to the TCC and/or the RBC, and the TCC sends the C2 speed restriction information to C2 onboard via an active transponder, and the RBC sends C3 speed restriction information via GSM-R. According to each embodiment of the present invention, through setting a TSRS in a railway system, a temporary speed restriction command can be obtained through connection with a CTC, and automatic distribution and collective management train control speed restriction commands for each TCC and RBC within the range of all line management and control can be realized by distributing the temporary speed restriction command to the related TCC, RBC, without train attendants of each station; in addition, CTCS-2 and CTCS-3 speed restriction commands can be set and cancelled simultaneously through the TSRS, which is beneficial to ensure consistency of two vehicle control modes.

[0025] In the above embodiments, after the TSRS sends the corresponding speed restriction command to the TCC and/or RBC, further includes the following steps: reporting, by the TSRS, the final actual speed restriction status result to the CTC after a synthetical judgment of the speed restriction command execution status by acquiring speed restriction receipt information of the TCC and/or RBC.

[0026] In the above embodiment, the temporary speed restriction command, i.e., he TSR information can also carry a CTC number and an operator ID. The TSRS uses the CTC number and the operator ID to the TSR information so as to carry out validity verification, verifying if the CTC and the operator have control permission. Based on the guaranteed safety of train control speed restriction settings, the TSRS system carries out executable verification to the speed restriction parameters, which is beneficial for guaranteeing the validity and safety of the speed restriction plan.

[0027] Next, examples will be given to demonstrate the distribution principle of the temporary speed restriction command. FIG. 3 is a diagram of a usage of covering a speed restriction sign according to the embodiment of the present invention. As shown in FIG. 3, TCC, for example, realizes TSR command splits by adding modes of coverage of speed restriction signs in the interface protocol.

[0028] When the covered modes of the starting and end milestones (i.e. the speed restriction zone starting point and the speed restriction zone end point) of the temporary speed restriction command exceeds the line jurisdiction, it is required to add coverage speed restriction signs so as to inform the TCC to recognize the validity of the speed restriction point mileage exceeding the station jurisdiction. For station B as shown in FIG. 3, it can be considered to execute full line speed restriction. If the milestones of the speed restriction zone starting point and the speed restriction zone end point are within the line jurisdiction of the station TCC, the coverage speed restriction sign is only allowed to use 00b. In the figure,
00b represents the milestone is located within the range of the TCC line jurisdiction;
01b represents the milestone is located on the forward side of the outside of the TCC line jurisdiction (the upward direction of the downward line or the downward direction of the upward line);
10b represents the milestone is located on the reverse side of the outside of the TCC line jurisdiction (the downward direction of the downward line or the upward direction of the upward line).

[0029] After covering the speed restriction signs, the original command information can be preserved, making it easy to match the speed restriction command, and then integrate speed restriction status.

[0030] The adaptive adjustment for the C2 and C3 train control systems of the embodiment is that, because the C3 train control system additionally has a RBC device comparing to the C2 train control system, if only the C2 line does not match the RBC, the TSRS does not have to split the issued speed restriction command to the RBC.

[0031] FIG. 4 is a transition graph of a life-cycle maintenance state including a speed restriction TSR command according to the embodiment of the present invention. FIG. 5 is a transition graph of a life-cycle maintenance state without a speed restriction TSR command according to the embodiment of the present invention. As shown in the figures, the TSR commands are assigned as the "with speed restriction" setting and the "without speed restriction" setting. The CTC dispatcher takes the TSR setting command mode with speed restriction value of "without speed restriction" as the speed restriction cancellation command of the original TSR.

[0032] As seen from the figures, before the TSRS sends the corresponding temporary speed restriction command to the related TCC and/or RBC, it has to receive the activation command and the execution command sent by the CTC in sequence, and then sending. If the CTC has to cancel the temporary speed restriction command sent before, it sends the cancellation command to the TSRS; after the TSRS receives the cancellation command sent by the CTC, it sends the cancellation command to the TCC and/or the RBC, and carries the corresponding command identifier so as to identify which temporary speed restriction command is cancelled.

[0033] The classification description related to the TSR command status is shown in Table 1.

Table 1

Main class	Subclass	Description
To be executed	Not yet activated	Pass the verification during the proposed period
	Verification setting succeed	Pass the verification during the activation period
Reminded	Can be activated reminded	Close to the plan execution starting time point, remind once every 10 minutes as a default
	Can be set reminded	Remind when the line is empty
	Being still partly executed and needed to be processed reminded	Because of the connection fault of partial device communications, confirm and examination on the scene is needed
	Execution cancellation succeed	Cancel the successful set speed restriction command, only remind once
	Execution withdrawing succeed	Cancel the not-yet-set speed restriction command, only remind once
	Timeout not set reminded	Exceed the plan execution end time point, still no setting, continue reminding
In execution	Execution setting succeed	Setting is valid
	Verification cancellation succeed	Pass verification, cancel verification

[0034] The distribution embodiment also provides a processing strategy for not losing the train control system speed restriction, including the file storage technology and automatic reissuing technology, wherein,

[0035] Regarding the file storage technology:

When initializing the TSRS, the application data alternated by the external device can be responded only after completing reading the speed restriction command storage file. For example, successful reading or reading failure of continuous 20 cycles can be regarded as read completes.

[0036] When the TSRS loads the command, it should verify the version of the head of the storage file and the last storage date, if they do not match, it should not load the file data into the memory. It is not compatible with the old format version; the storage date is only valid that day.

[0037] When the TSRS completes reading all TSR command parameters, it should make TCC and RBC attribution splits for each command, so as to enter the complete TSR command state maintenance cycle.

[0038] The TSRS should set all speed restriction commands successfully loaded from the file as not-yet activated status.

[0039] A detecting that there is command status change in the cycle, and there is need to update the storage, it should write all speed restriction commands into a cache one-time. Then send it to a NVH module (a local hard disk) for storing, and stores according to the predefined file storage format, where the file storage format includes the current date and version number. However, it does not store the speed restriction command in withdrawing status and cancellation status.

[0040] The head of the storage cache need to fill the current system date and version number, so as to read back and verify: if the read back date conforms to the current system date, permit all loading; if the version number does not conform to the current format version, delete all.

[0041] Regarding automatic reissuing technology:

When any of the following circumstances appears, acknowledge that the temporary speed restriction command statuses of the TSRS and TCC and/or RBC are inconsistent, and then the TSRS automatically reissues the stored temporary speed restriction command to the TCC and/or RBC. After completing the reissuing, it can automatically issue the speed restriction status initial confirmation command, so that the TCC and RBC sends all speed restriction information to related vehicles:

When restarting the TSRS, TCC, RBC devices on power, or recovering after interrupting the communication, or the TSRS detects that the total TSR command number given feedback by the TCC and RBC and the total command number stored locally by the TSRS are inconsistent for continuous 5s, or the TSRS sends an all refresh request on the hour to the TCC and the RBC.

[0042] If restarting with the TCC or RBC executing the TSR command, and the TSRS is already in initial status, the TSRS can automatically reissue the execution of TSR command to the TCC or RBC.

[0043] If there is inconsistency between the TSRS and TSR command status of the TCC and RBC, it should remind the dispatcher to confirm all the current inconsistent speed restriction status; the dispatcher should retrigger the TSR setting and cancel the process according to actual situation. Once the dispatcher completes confirming all speed restriction status, the TSRS is informed to issue line speed restriction initialization confirmation command to the TCC and the RBC.

[0044] If the TSRS has completed the line speed restriction initialization confirmation, and the status of TSRS are consistent with the status of the TCC and the RBC, the TSRS can automatically reissue the line speed restriction initialization confirmation command, and then can reissue the temporary speed restriction command need to be stored.

[0045] If the TSRS considers a TSR command is under execution status, however, the TCC and RBC has not executed the speed restriction command, the TSRS should not issue the line speed restriction initialization confirmation command to the TCC and RBC.

[0046] According to the present invention, the method for sending a temporary speed restriction command in C3 system can provide activation reminder and set reminder to the temporary speed restriction command, which is beneficial to guarantee the timeliness of the speed restriction validity; it can store train control speed restriction command parameters, which is beneficial to guarantee the completeness of the speed restriction command, even blackout occurs and the device is restarted, it cannot be lost; it can carry out synthetical determination to the speed restriction command execution status, so as to correctly guide the dispatcher the validity of the speed restriction command; it can also automatically reissue speed restriction command and initialization command to the TCC and RBC, which is beneficial to guarantee the completeness of the speed restriction command, and improve the usability of the train control system.

[0048] In particular, the CTC system protocols the contents of the temporary speed restriction command, and then sends a temporary speed restriction command (TSR), where at least the following information are carried: the speed restriction value, the speed restriction zone starting point, the speed restriction zone ending point, the line number, the scheduling command number and the station number. The TSRS receives TSR information through the receiving module 11, and the distribution module 12 splits the TSR information, i.e., after the receiving module 11 receives the temporary speed restriction command issued by the CTC system, the distribution module 12, according to the speed restriction zone starting point, the speed restriction zone end point, and the jurisdiction of related TCC and/or RBC carried, distributes the temporary speed restriction command to the related TCC and RBC for execution. The distribution module 12 resets through the field information of the speed restriction zone starting point and the speed restriction zone end point in the temporary speed restriction command sent to a specific TCC and/or RBC, and the sending module 13 sends the temporary speed restriction command to the TCC and/or RBC. The TCC system is responsible for controlling the transponder to send the corresponding TSR information to the C2 train; the RBC system is responsible for sending the corresponding TSR information to the C3 train through GSM-R. After the train equipped with the ATP vehicle device receives the TSR information, the train is controlled to run according to the speed restriction requirement.

[0055] In the control system provided by the embodiment, the interface devices between each device are arranged as follows.

[0056] Regarding the interface of the TSRS and the CTC:

When the dispatcher operates and protocols the temporary speed restriction command, the CTC should send the parameter information of the temporary speed restriction command to the TSRS, at least including the CTC number, the operator ID, the dispatching command number, the train number, the speed restriction value, the speed restriction zone starting point, the speed restriction zone end point, the line number, and the speed restriction reason code;

when the TSRS sends back the wrong code of the temporary speed restriction command to the CTC, the CTC should analyze the display according to the arranged meaning of the wrong code;

the TSRS should simultaneously return the command execution result to the CTC for displaying.

[0057] Regarding the interface between the TCC and RBC:

The TSRS should use timely modes to issue operation commands of setting execution, cancellation verification, and cancellation execution to the TCC and RBC, and indicate a corresponding command identifier.

[0058] When the communications between the TSRS and TCC, RBC recover, the TSRS should send a refreshing request commands to the TCC and RBC, and the TCC and RBC should return all the temporary speed restriction commands at execution status.

[0059] Regarding the interface between adjacent TSRSs:

The adjacent TSRSs should timely exchange temporary speed restriction commands related to the jurisdiction border and corresponding execution result information.

[0060] If the TSRS considers there is communication interruption between adjacent TSRSs, the TSRS should send warning to the CTC.
