Description

TECHNICAL FIELD

[0001] The present application relates to the field of rail transit automatic control technology, in particular to a setting method and device for temporary speed limit of the whole line based on a full-automatic operation system. BACKGROUND

[0002] In the full-automatic operation system of urban rail transit, when external conditions change, for example, the line is replaced, construction is in progress nearby, the open track rains, and other temporary requirements for train speed limit operation in a certain area, the dispatch personnel need to manually set the temporary speed limit according to the requirements of the temporary speed limit dispatch command through the control center workstation, the train automatic supervision (ATS) receives the command and sends the temporary speed limit command to the data management server (DMS) for execution, the DMS checks the legality of the command, and when the command is valid, the command is forwarded to the regional controller again, the regional controller feeds back the result of the temporary speed limit command to the DMS, and the DMS sends the feedback result to the ATS again, and displays the final temporary speed limit information on the ATS interface. At present, when setting the temporary speed limit of the whole line, the dispatch personnel need to manually input the temporary speed limit start kilometer marker, end kilometer marker, speed limit direction and other information, or different manufacturers input the start logical section ID, end logical section ID, speed limit value and other information when setting the temporary speed limit, and the dispatch personnel can only set the temporary speed limit in a certain area of the same direction for each logical section range at a time, and the input principles of different manufacturers for setting the temporary speed limit are different. If there are many areas that need to set the temporary speed limit, they need to be set respectively, which cannot be set at the same time, and the interfaces for setting the temporary speed limit are relatively complex, and there are many interactive systems, which leads to complex operation of the temporary speed limit of the whole line, long time consumption and low efficiency.

[0059] In step S101, the train automatic monitoring system receives a full-line temporary speed limit command, wherein the full-line temporary speed limit command carries identification information of a target line control system under jurisdiction of the train automatic monitoring system and a target speed limit value.

[0064] Figure 2 A flow chart of a method for setting a temporary line speed limit based on a full-automatic operation system according to an optional embodiment of the present application is shown in FIG. 1. Figure 2 The method shown in FIG. 1 can be performed by a line control system, and specifically includes the following steps.

[0065] In step S201, the line control system receives a temporary line speed limit command sent by a train automatic monitoring system, wherein the temporary line speed limit command carries a target speed limit value.

[0066] In step S202, the line control system checks the legality of the temporary line speed limit command.

[0067] In step S203, when it is determined that the temporary line speed limit command is legal, the line control system performs speed limit control on a train entering a speed limit region or a train at a target distance from the speed limit region according to the temporary line speed limit command.

[0068] As an optional embodiment, the legality check of the temporary line speed limit command by the line control system includes:

[0069] checking whether the temporary line speed limit command conforms to a preset command format;

[0070] checking whether the target speed limit value exceeds a preset maximum static speed limit value;

[0071] checking whether the line control system belongs to a jurisdiction range of the train automatic monitoring system;

[0072] when the temporary line speed limit command is set for the first time successfully and the temporary line speed limit command is set again, checking whether the temporary line speed limit command exceeds a target time, wherein the target time is a time between a start time of the first-time setting and an end time of the second-time setting;

[0084] clearing the full-line temporary speed restriction command, and sending a failure message to the train automatic monitoring system, wherein the failure message is used to indicate that the full-line temporary speed restriction command is not legal.

[0085] The embodiments of the present application are described and explained below by preferred embodiments.

[0086] The preferred embodiment provides a setting method of full-line temporary speed restriction based on a full-automatic operation system. The full-line temporary speed restriction setting can be set by a dispatcher on the interface of a train automatic monitoring system (ATS), and finally the speed restriction information is sent to a train, and the train performs overspeed protection according to the speed restriction information. The specific flow process of the full-line temporary speed restriction command is as shown in Figure 3 , and the specific process is as follows:

[0087] A. The dispatcher sets a full-line temporary speed restriction command on the interface of the ATS system;

[0088] B. The ATS system receives the temporary speed limit command set on the interface and distributes it to all LC systems under its jurisdiction according to the set temporary speed limit command.

[0089] C. After receiving a temporary speed limit command for the entire line, the LC system stores the command in a file. When the LC system restarts, it can automatically set the temporary speed limit command based on the stored command and send the result back to the ATS to notify the user that the temporary speed limit command is valid.

[0090] D. When the LC system detects that a train is about to enter a speed-limited area or is already in a speed-limited area, it sends the corresponding temporary speed limit command for the entire line to the train.

[0091] Dispatchers can directly set temporary speed limits for the entire line through the interface, quickly and easily completing the setting process. Simultaneously, the ATS distributes temporary speed limit information to the LC systems under its jurisdiction. The ATS processes temporary speed limit commands for the entire line as follows: Figure 4 As shown, the specific steps include:

[0092] Step S401: The dispatcher sets a temporary speed limit order for the entire line, which corresponds to the description process of A, F, and G below.

[0093] Step S402: ATS distributes commands to each LC system, as described in section B below.

[0094] Step S403, ATS timing judgment, corresponding to the process described in C below; if within the timing period, execute step S404; if the timing is completed, execute step S405.

[0095] Step S404, ATS timing judgment and processing, corresponds to the process described in D below.

[0096] Step S405, ATS timing completion processing, corresponds to the process described in E below.

[0097] A. Open the interface for setting temporary speed limits across the entire line, select the speed limit value to be set (which can be set according to the actual requirements on site), and the LC system within the jurisdiction of the entire line is selected by default.

[0098] B. After receiving the temporary speed limit command message from the interface, ATS obtains the IDs of all managed LC systems within the entire line through the configuration data. It then sends the temporary speed limit command and speed limit value to each managed LC system, starts the command timing, and records the commands sent to each LC system.

[0099] C. The ATS enters a timing wait process (10-second timing standard), during which it receives each feedback result from the LC system. It checks whether the execution result of the received LC system feedback command was successful, and whether the command fed back by the LC system matches the cached command. If the feedback result is successful and the command matches, the command is considered successful; if the returned result is a failure or the command is inconsistent, the command is considered to have failed.

[0100] D. The ATS enters a 10-second timing wait. During this 10-second wait, it checks whether the temporary rate-limiting command for the entire line was successfully issued to each LC system. If the feedback from each LC command issuance is successful, it indicates that the entire command set by the dispatcher is successful, and feedback will be sent to the interface to inform the dispatcher that the command setting was successful, and the timer will be cleared. If, during the 10-second wait, all LC system command checks result in failure, or a single command check result in failure, it indicates that the entire command set by the dispatcher has failed, and feedback will be sent to the interface to inform the dispatcher that the command setting failed and should be reset. Simultaneously, the temporary rate-limiting command cached by the ATS will be cleared.

[0101] E. When the ATS completes the timing (10 seconds), it detects that there is still no feedback information received from the LC system. This indicates that there is a communication interruption between the ATS and the LC system, or that the LC system has failed to respond to the LC system command. In either case, the entire command set by the dispatcher is considered to have failed. The failure is reported to the interface to inform the dispatcher that the command setting has failed and that they should reset it. At the same time, the cached temporary speed limit commands for the entire line are cleared.

[0102] F. When the ATS detects that the entire command set by the dispatcher was successful, the dispatcher needs to repeat the command setting to ensure its security and reliability and prevent errors such as randomness or human error. The ATS then reissues and checks the command's success and failure according to the above steps and informs the dispatcher of the results.

[0103] G. Optionally, when setting a temporary speed limit command for the entire line in the interface, you can select to set a temporary speed limit for the entire line within the jurisdiction of a certain LC. When the ATS issues a command and checks the success or failure of the command, it can only target the currently selected LC area, which greatly facilitates the actual application in the field.

[0104] After receiving a temporary speed limit command from the ATS (Automatic Train Protection System), the LC (Limited Line Control) system checks the command's validity. If valid, the command is written to a file, and the result is sent back to the ATS. When a train enters the designated temporary speed limit area, temporary speed limit information is immediately sent to the train. The LC system's process for handling temporary speed limit commands across the entire line is as follows: Figure 5As shown, the specific steps include:

[0105] Step S501: The LC system checks the validity of the temporary speed limit command across the entire ATS line, corresponding to the process described in A' below.

[0106] In step S502, the LC system determines the validity of the command. If it is valid, step S503 is executed; otherwise, step S507 is executed.

[0107] Step S503: After the LC system verifies the legality of the command, it maps the temporary speed limit command for the entire line to the specific track sections within its jurisdiction, corresponding to the process described in B' below.

[0108] Step S504: After the LC system checks the legality of the command and passes the verification, it writes the temporary speed limit command for the entire line to the temporary speed limit storage file, which corresponds to the process described in C' below.

[0109] Step S505: After the LC system verifies the legality of the command, it sends a command takeover notification to the ATS, which corresponds to the process described in D' below.

[0110] Step S506, the train enters or is about to enter the marked temporary speed-limited track area for processing, corresponding to the process described in F' below.

[0111] Step S507, the LC system checks the command's validity and then handles the subsequent steps, which correspond to the process described in E' below.

[0112] A' After receiving the temporary speed limit command from the ATS, the LC system needs to check the legality of the command. The checks are as follows:

[0113] 1. Check if the command is a temporary speed limit command for the entire line;

[0114] 2. Check whether the speed limit setting does not exceed the maximum static speed limit of the line (for example, if the maximum speed limit of the line is 100, and the temporary speed limit is set to 120, then the temporary speed limit setting is meaningless).

[0115] 3. Check whether this LC system is within the jurisdiction of the main line (temporary speed limits are not supported for the entire line in the depot area).

[0116] 4. Check if the command has timed out (the timeout period is 2 minutes, the time from setting the temporary speed limit across the entire line to repeating the temporary speed limit setting command; this item is not checked when setting the temporary speed limit across the entire line, but it is checked when repeating the temporary speed limit setting command).

[0117] 5. Check if the commands are consistent (whether the command to set a temporary speed limit for the entire line and the command to repeat setting a temporary speed limit for the entire line are consistent; do not check this item when setting a temporary speed limit for the entire line, but check this item when repeating setting a temporary speed limit for the entire line).

[0118] B' After the LC system checks the legality of the commands and passes the verification, it maps the temporary speed limit command for the entire line to specific track sections within its jurisdiction. For example, if the temporary speed limit for the entire line is set to 60 km / h, the LC system traverses each track section within its jurisdiction and checks the static speed limit of the current track section. If the static speed limit is greater than the set temporary speed limit of 60 km / h, the current track section is marked with a temporary speed limit of 60 km / h. If the static speed limit is less than the set temporary speed limit of 60 km / h (45 km / h is less than 60 km / h in the track area of ​​the turnout area), the current track section is considered not to need to be marked with a temporary speed limit.

[0119] After the validity of C' and LC's checks on the commands is passed, the temporary speed limit command for the entire line is written to the temporary speed limit storage file, maintaining both the temporary speed limit command and the speed limit value. Simultaneously, the temporary speed limit command and speed limit value for the entire line are also saved in the program. When the LC system is powered on and restarted, the cached temporary speed limit command for the entire line will be lost. Therefore, after power-on and restart, the temporary speed limit storage file is read directly, along with the temporary speed limit command and speed limit value for the entire line. Following the same procedure as in step B', the temporary speed limit command for the entire line is mapped to the specific track sections within its jurisdiction. Simultaneously, the effective temporary speed limit command for the entire line is fed back to the ATS to indicate to the caller that the stored temporary speed limit command for the entire line is valid.

[0120] After D' and LC check the legality of the commands, complete steps B' and C' (map the temporary speed limit command for the entire line to specific track sections within the jurisdiction and write the temporary speed limit command for the entire line to the temporary speed limit storage file), and then report the execution result of the command to ATS: success.

[0121] The validity of the E' and LC check commands is deemed unsuccessful if any one of the check items is met (e.g., checking the first 3 items of setting a temporary speed limit across the entire line, or checking all 5 items of repeatedly setting a temporary speed limit across the entire line). The LC system then clears the command. If a repeatedly set temporary speed limit across the entire line fails, the previously set temporary speed limit command must also be cleared. Simultaneously, the LC system sends the result of the command check failure as a failure to the ATS with the same reason.

[0122] F' When a temporary speed limit is marked on the track section ahead of the train (within the movement authorization range) or in the area where the train is currently operating, the temporary speed limit information is sent to the train for overspeed protection. Because the temporary speed limit uses the same element for marking the track section, train position, movement authorization, and interface fields, the algorithm is greatly simplified in areas such as mixed calculation of movement authorization and interface output, thus improving operational efficiency.

[0123] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0124] 1. Simplify the operation for callers. When it is necessary to set temporary speed limits for a large range, it is not necessary to select specific logical segments to set temporary speed limits. Instead, it is only necessary to set the entire line through commands, reducing the time and error rate of setting commands.

[0125] 2. Simplify the command flow process by sending commands directly to the LC system via ATS. After the LC system checks the command and finds it successful, it stores the command directly. When the train is running or about to run on a track section marked with a temporary speed limit, a temporary speed limit command is immediately sent to the train for overspeed protection, thereby improving the overall system's command response time.

[0126] 3. The temporary speed limit settings have been changed from logical segments to track segments, with train position and movement authorization protection points all using a unified element unit. This unification eliminates the need for element state transitions, simplifying the search, interception, and calculation of temporary speed limits, improving operational efficiency, and reducing the probability of errors.

[0127] It should be noted that the steps shown in the above process or in the flowchart of the accompanying figures can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.
