[0002] With the development and progress of rail transit technology, advanced train control systems, signal systems, positioning systems and communication systems can achieve continuous detection and rapid response to train status and track conditions in the entire line operation section or test site. In some train operation scenarios, in order to ensure the safety of train operation, the train automatic protection system (hereinafter referred to as ATP system) will be used to protect the train from overspeeding to avoid the safety hazards caused by overspeeding.

[0003] However, in order to ensure the running safety of trains, the speed limit value recorded in the ATP system for overspeed protection is usually low, which makes it easier for trains to trigger emergency braking due to overspeeding, thus affecting the running efficiency of trains in the mainline section.

Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining".

[0016] In addition, it should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in one or more embodiments of this specification are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0017] First, the terms involved in one or more embodiments of this specification are explained.

[0018] RM (Restricted Manual Driving Mode): RM mode is a driving mode used in specific situations. In this mode, the train is manually driven by the driver, but the running speed is limited, usually not exceeding 25km / h. If the train speed exceeds this limit, the ATP system will trigger emergency braking to ensure the safety of the train operation.

[0019] ATP (Automatic Train Protection): ATP is an on-board subsystem that directly ensures train safety. It achieves autonomous positioning through speed sensors, speed radars and odometers, and uses transponders to correct the train's position and speed information. It obtains the train's movement authorization (MA) through wireless communication (or variable data transponders), calculates and generates the train's control speed curve, and protects the train's position and speed to ensure driving safety.

[0020] CBTC (Communication Based Train Control System) is a continuous train automatic control system built through active train positioning technology that does not rely on trackside train occupancy detection equipment, continuous train-to-ground two-way data communication technology, and on-board and ground processors that can perform safety functions.

[0021] MMI (Man Machine Interaction) refers to a platform for two-way information exchange of various symbols and actions between people and computer systems or machine equipment. Its main function is to convert human intentions into a form that can be understood and processed by computer systems or machine equipment, and at the same time convert the feedback of computer systems or machine equipment into a form that can be perceived and understood by humans. The MMI interface is responsible for converting information into a form acceptable to humans, so that users can interact with the system conveniently. The MMI interface usually includes components such as display screens, buttons, and touch screens to provide functions such as information display, parameter setting, and control operations.

[0022] Emergency braking: Emergency braking is usually a braking measure taken by the driver or the vehicle's automatic control system when a vehicle encounters an emergency or danger during driving. It can reduce the speed of the vehicle or stop it completely in a short time.

[0023] Zero speed: refers to the state where the train is stationary and the speed is 0.

[0024] Main line: refers to the main line in the rail transit system, which is used to connect various stations and carries the main passenger operation tasks. The main line usually consists of two parts: the section main line and the station main line. Among them, the section main line is used to connect two adjacent stations and is the main channel for trains to run between stations; the station main line is located inside the station and is used for train stops, passengers getting on and off, and trains passing.

[0025] Depot line: It is a line set up for train parking, maintenance and preparation. It is usually composed of yard lead-out line, yard parking line and train maintenance line. The setting of these lines can meet the needs of trains in different situations such as parking, maintenance and preparation. In the depot line, the running speed of the train is relatively low, and it is mainly used for train parking, maintenance and preparation. In addition, the depot line also undertakes the task of trains entering and exiting the depot (or parking lot), and is an important channel for trains to enter the depot from the operating line or from the depot to the operating line.

[0026] In the train operation scenario based on rail transit, when a fully automatic driving train fails and is degraded and cannot maintain the CBTC level, or the train is locally awakened and leaves the depot, before the upgrade conditions are met, in order to ensure the safe operation of the train, the train is usually controlled to run in RM mode and the train is protected from speeding through the ATP system to avoid the safety hazards caused by speeding.

[0027] Generally, the default speed limit value of the RM mode is 25km / h. If the train is currently running on the main line, this speed limit value will seriously affect the train's operating efficiency within the main line section and cannot meet the train operation needs. Therefore, when the train has a position during operation in the RM mode, it is usually possible to obtain a speed limit value that matches the current position, thereby adjusting the default speed limit value. However, if the train has no position, it is difficult to flexibly adjust the default speed limit value while ensuring the safety of the train operation. In this case, the problem of low train operation efficiency cannot be solved.

[0028] Based on this, an embodiment of the present specification provides a train management method, receiving an update instruction sent by a display unit of a target train, wherein the update instruction carries an update speed limit value, and the update speed limit value is used to update the initial speed limit value of the target train in a specified operating mode; checking whether the target train meets the preset update conditions; if so, sending a prompt message to the display unit to confirm the update speed limit value; upon receiving the confirmation message sent by the display unit in response to the prompt message, updating the initial speed limit value to the updated speed limit value. By receiving the update instruction, when the target train passes the verification and receives the confirmation message sent in response to the prompt message, the initial speed limit value of the target train in the specified operating mode can be updated to the updated speed limit value, thereby realizing the update of the initial speed limit value, thereby realizing the flexible adjustment of the speed limit value in the specified operating mode on the basis of ensuring the safety of train operation, and improving the train operation efficiency.

[0029] In this specification, a train management method is provided. This specification also involves a train management system, a train management device, a computing device, a computer-readable storage medium, and a computer program product, which are described in detail one by one in the following embodiments.

[0030] See also Figure 1 , Figure 1 The train management system 100 includes a display unit 102 and a control unit 104 .

[0031] Display unit 102: used to obtain the updated speed limit value of the target train, and send an update instruction carrying the updated speed limit value to the control unit, wherein the updated speed limit value is used to update the initial speed limit value of the target train in a specified operating mode.

[0032] Control unit 104: used to receive update instructions; check whether the target train meets the preset update conditions; if so, send a prompt message to the display unit to confirm the update of the speed limit value.

[0033] The display unit 102 is also used to obtain confirmation information for the prompt information and send the confirmation information to the control unit.

[0034] The control unit 104 is further configured to update the initial speed limit value to the updated speed limit value upon receiving confirmation information sent by the display unit in response to the prompt information.

[0035] When the train is running in RM mode on the section mainline, the driver can be allowed to manually input an updated speed limit value through the MMI system, thereby changing the initial speed limit value of the train in RM mode.

[0036] In one or more embodiments of the present specification, the display unit may be understood as an MMI system, and the control unit may be understood as an ATP system.

[0037] In actual applications, when the driver inputs an updated speed limit value, the MMI can generate an update instruction carrying the updated speed limit value and send the update instruction to the ATP system. The ATP system verifies whether the target train meets the preset update conditions. If the verification passes, it sends a prompt message to the MMI system to confirm the updated speed limit value. Upon receiving the prompt message, the MMI system can display the updated speed limit value and prompt the driver to confirm. When the driver confirms the updated speed limit value, the MMI system generates a confirmation message for the prompt message and sends the confirmation message to the ATP system. Upon receiving the confirmation message, the ATP system updates the initial speed limit value in the system to the updated speed limit value, and determines whether to trigger the train emergency braking based on the updated speed limit value.

[0038] By applying this embodiment, when the RM speed limit value is allowed to be modified, the updated speed limit value is input through the display unit, and the control unit verifies the updated speed limit value, so as to realize the first confirmation of whether the target train meets the speed limit value update conditions; by sending a prompt message to the display unit when the control unit verifies it, and receiving the confirmation message sent by the display unit for the prompt message, it is possible to realize the second confirmation of whether the target train can update the speed limit value. Through the two confirmation processes, it is possible to realize the real-time update of the initial speed limit value under the specified operation mode, which can improve the train operation efficiency, and ensure that the train meets the conditions for updating the RM speed limit value, thereby ensuring the safety of train operation.

[0039] See also Figure 2 , Figure 2 A flow chart of a train management method provided according to an embodiment of the present specification is shown, wherein the train management method is applied to a control unit and specifically includes the following steps.

[0040] Step 202: receiving an update instruction sent by a display unit of a target train, wherein the update instruction carries an update speed limit value, and the update speed limit value is used to update an initial speed limit value of the target train in a specified operating mode.

[0041] In actual applications, when the target train is running on the section main line, an update instruction sent by the display unit of the target train can be received.

[0042] Specifically, the display unit can be understood as a man-machine interface MMI. The initial speed limit value can be understood as the default speed limit value of the target train in a specified operating mode, that is, the original speed limit value. The update instruction is used to instruct the control system to change the initial speed limit value.

[0043] In an optional embodiment of the present specification, the update instruction can be generated based on the user manually inputting the updated speed limit value through the display unit. For example, the driver can manually input the updated speed limit value in the specified operating mode speed limit value update input box on the display unit according to the needs in the actual application scenario.

[0044] In another optional embodiment of the present specification, the update instruction can also be automatically triggered to be generated based on the train meeting the update condition. For example, when the train is on the main line and recovers from the emergency braking state, the update instruction carrying the preset update speed limit value can be automatically generated.

[0045] According to an optional embodiment of the present specification, receiving an update instruction sent by a display unit of a target train may include the following steps: When the current operation mode of the target train is the designated operation mode, determining whether the target train has a current position; If not present, an update instruction sent by the display unit of the target train is received.

[0046] Specifically, the designated operation mode may be the RM mode. The current position may be understood as the current positioning information of the target train.

[0047] In actual applications, when the target train has positioning information, that is, when the target train has a current position, the speed limit value corresponding to the specified operation mode is usually obtained based on the current position. When the target train has no positioning information, that is, when the target train does not have a current position, since the corresponding speed limit value cannot be obtained based on the position, if the target train is currently running in the specified operation mode, the driver can be allowed to manually input an updated speed limit value, so as to flexibly adjust the speed limit value of the train in the specified operation mode according to actual needs.

[0048] By applying this embodiment, when the current operating mode of the target train is the designated operating mode, it is determined whether the target train has a current position, and when there is no current position, an update instruction is received. This enables the speed limit value of the designated operating mode to be updated when the train has no position, thereby better meeting the train operation needs.

[0049] Step 204: Check whether the target train meets the preset update conditions.

[0050] In practical applications, when the control unit receives the updated speed limit value, it can verify whether the target train meets the preset update conditions. This verification process is the first confirmation of the updated speed limit value.

[0051] Specifically, the preset update condition can be used to determine whether it is currently appropriate to modify the initial speed limit value of the target train.

[0052] According to an optional embodiment of the present specification, checking whether the target train meets the preset update condition may include the following steps: Obtain the attribute information of the target train; Check whether the update speed limit value and attribute information meet the preset update conditions.

[0053] Specifically, the attribute information can be used to describe various states of the target train during operation.

[0054] In practical applications, checking whether the target train meets the preset update conditions may include checking whether the updated speed limit value is legal, and checking various states of the target train during operation.

[0055] By applying this embodiment, by obtaining the attribute information of the target train, it is possible to determine whether it is appropriate to modify the initial speed limit value of the train according to the various states of the train, and it is possible to verify whether the updated speed limit value sent by the display unit complies with the speed limit value specified in the specified operating mode, thereby ensuring the safety of the train in the specified operating mode.

[0056] Further, the attribute information may include the current position and current running state of the target train; the preset update condition may include a preset value range and a preset running state corresponding to the specified running mode; and checking whether the updated speed limit value and the attribute information meet the preset update condition may include the following steps: Determine whether the updated speed limit value is within the preset value range, and determine whether the current position exists and whether the current operating state conforms to the preset operating state.

[0057] Specifically, when the designated operation mode is RM mode, the preset value range may be 25km / h-75km / h. The current operation status can reflect the current operation status of the train, and thus can be used to determine whether the train is currently safe and whether the initial speed limit value can be modified.

[0058] By applying this embodiment, by judging whether the updated speed limit value is within the preset value range, and judging whether the current position exists and whether the current operating state conforms to the preset operating state, it is possible to make a first confirmation on whether the initial speed limit value can be modified based on the updated speed limit value, thereby achieving a more rigorous verification of the target train and ensuring the safety of train operation.

[0059] According to an optional embodiment of the present specification, the current running state includes the current running speed and the hardware state; after verifying whether the target train meets the preset update conditions, the following steps may also be included: When the updated speed limit value is within the preset value range, the current position does not exist, the current running speed is zero speed, and the hardware status is normal, it is determined that the target train meets the preset update conditions.

[0060] In actual applications, when the target train runs in the specified operating mode and the updated speed limit value input through the display unit is within the preset value range, that is, the updated speed limit value is legal, and the current position does not exist, that is, the train has no position, the current operating speed is zero speed, there is no hardware failure, and there are no other abnormalities, then it can be judged that the target train meets the preset update conditions and passes the verification.

[0061] By applying this embodiment, by determining whether the target train meets the preset update conditions, it is possible to ensure that the updated speed limit value is modified under the condition of train operation safety, thereby achieving the first confirmation of the updated speed limit value.

[0062] Step 206: If the conditions are met, a prompt message is sent to the display unit to confirm the update of the speed limit value.

[0063] In actual applications, if the verification result satisfies the preset update condition, the control unit may send a prompt message to the display unit to confirm the update of the speed limit value.

[0064] Specifically, the prompt information may be used to prompt the display unit to perform a second confirmation on the updated speed limit value.

[0065] Optionally, the prompt information may carry an updated speed limit value. Upon receiving the prompt information, the display unit may display the updated speed limit value for the driver to confirm.

[0066] According to an optional embodiment of the present specification, during the secondary confirmation process, if the driver confirms that the input of the updated speed limit value is correct, then after sending a prompt message confirming the updated speed limit value to the display unit, the following may also be included: The receiving display unit sends confirmation information in response to the prompt information.

[0067] Specifically, the confirmation information can be understood as information for confirming the updated speed limit value, indicating that the updated speed limit value has passed the second confirmation.

[0068] According to another optional embodiment of the present specification, during the secondary confirmation process, if the driver finds that the updated speed limit value is incorrectly input, or the driver wants to modify the updated speed limit value, after sending a prompt message to confirm the updated speed limit value to the display unit, the following steps may also be included: When receiving the modification instruction sent by the display unit in response to the prompt information, return to execute the step of verifying whether the target train meets the preset update condition, wherein the modification instruction carries the modification speed limit value.

[0069] Specifically, the modification instruction may be understood as an instruction for modifying the updated speed limit value.

[0070] In actual applications, during the secondary confirmation process, when the display unit receives a new updated speed limit value, that is, when the speed limit value is modified, a new update instruction can be resent to the control unit to instruct the control unit to return to the first confirmation process and recheck the new updated speed limit value; or a modification instruction for the updated speed limit value can be sent to the control unit, and a modified speed limit value different from the updated speed limit value can be carried in the modification instruction, instructing the control unit to return to the first confirmation process and recheck the modified speed limit value.

[0071] By applying this embodiment, when the control unit receives the modification instruction sent by the display unit in response to the prompt information, it returns to execute the step of verifying whether the target train meets the preset update conditions. This ensures that each newly input speed limit value is confirmed twice, thereby ensuring the safety of train operation.

[0072] Step 208: When receiving confirmation information sent by the display unit in response to the prompt information, the initial speed limit value is updated to the updated speed limit value.

[0073] In actual applications, when the control unit receives confirmation information sent by the display unit in response to the prompt information, the initial speed limit value in the control unit may be updated to the updated speed limit value.

[0074] Specifically, the confirmation information indicates that the display unit has passed the secondary confirmation of the updated speed limit value.

[0075] In actual applications, when the train is running in a specified operating mode, the control unit can monitor the current running speed of the train in real time, and trigger emergency braking of the train when the running speed exceeds the speed limit corresponding to the specified operating mode, thereby avoiding the danger of speeding.

[0076] When the speed limit value in the control unit is the default speed limit value, that is, the initial speed limit value, when the control unit detects that the train speed exceeds the default speed limit value, it will trigger the train to perform emergency braking.

[0077] When the speed limit value in the control unit is modified to the updated speed limit value, the control unit will trigger the train to perform emergency braking if it detects that the train speed exceeds the updated speed limit value.

[0078] That is, according to an optional embodiment of the present specification, after the initial speed limit value is updated to the updated speed limit value, the following steps may also be included: When it is monitored that the current running speed of the target train exceeds the updated speed limit value, the target train is triggered to perform emergency braking, wherein the emergency braking refers to the running speed of the target train being reduced from the current running speed to zero speed.

[0079] By using this embodiment, when the current running speed of the target train is detected to exceed the updated speed limit value, the target train is triggered to perform emergency braking, which can avoid the danger of overspeeding of the train, and effectively ensure the safety of train operation while improving the running efficiency of the train on the section main line. In addition, since the speed limit value in the specified operation mode is updated from the initial speed limit value to the updated speed limit value, and the updated speed limit value is higher than the initial speed limit value, the train can trigger emergency braking less frequently when running on the section main line, thereby effectively improving the running efficiency of the train.

[0080] In actual applications, when the driver observes that he is about to pass a switch or the road conditions are bad, since maintaining a speed limit exceeding the initial speed limit (for example, 25km / h) may pose a safety risk, the updated speed limit value may be reset; alternatively, when the dispatcher informs the driver that the speed limit needs to be lowered, the updated speed limit value may be reset.

[0081] According to an optional embodiment of the present specification, after the initial speed limit value is updated to the updated speed limit value, the following steps may also be included: In response to a reset instruction sent by the display unit for updating the speed limit value, verifying whether the target train meets a preset reset condition; If satisfied, the updated speed limit value is reset to the initial speed limit value.

[0082] Specifically, the reset instruction can be used to specify that the updated speed limit value in the control unit is reset to the initial speed limit value. The reset instruction can be generated based on the driver operating the reset button on the display unit. The preset reset condition can be used to determine whether the target train can currently reset the speed limit value. The preset reset condition can specifically include: the current running speed of the target train should be lower than the initial speed limit value.

[0083] In the actual implementation process, if the driver determines that maintaining a higher speed limit will pose a safety risk, or if the dispatcher informs the driver that the speed limit needs to be lowered, the driver can control the train to slow down until the speed drops below the initial speed limit. At this time, the driver can press the "Set RM Speed ​​Limit" button on the MMI and click "Reset Speed ​​Limit". The MMI system will send a request to the ATP system to reset the RM speed limit to 25km / h. Based on the preset reset conditions, the ATP system will determine whether there is a safety risk in resetting the speed limit at this time. If it is determined that there is no safety risk, the ATP system can reset the speed limit in the system to the initial speed limit of 25km / h.

[0084] By applying this embodiment, by responding to the reset instruction sent by the display unit for the updated speed limit value, it is verified whether the target train meets the preset reset conditions; when the preset reset conditions are met, the updated speed limit value is reset to the initial speed limit value, and the updated speed limit value can be reset back to the initial speed limit value according to actual needs, thereby further ensuring the safety of train operation.

[0085] The train management method provided by an embodiment of the present specification is applied to receive an update instruction sent by the display unit of the target train, wherein the update instruction carries an update speed limit value, and the update speed limit value is used to update the initial speed limit value of the target train in the specified operation mode; check whether the target train meets the preset update conditions; if so, send a prompt message to the display unit to confirm the update speed limit value; and update the initial speed limit value to the updated speed limit value when receiving the confirmation message sent by the display unit in response to the prompt message. By receiving the update instruction, when the target train passes the verification and receives the confirmation message sent in response to the prompt message, the initial speed limit value of the target train in the specified operation mode can be updated to the updated speed limit value, thereby realizing the update of the initial speed limit value, thereby realizing the flexible adjustment of the speed limit value in the specified operation mode on the basis of ensuring the safety of train operation, and improving the train operation efficiency.

[0086] The following combination Figure 3 Taking the application of the train management method provided in this specification in adjusting the RM mode speed limit value as an example, the train management method is further described. Figure 3 A flow chart of the processing process of a train management method provided by an embodiment of this specification is shown.

[0087] When the train is on the main line and has no position, the driver is allowed to manually enter the RM speed limit value in the RM speed limit box on the MMI interface to adjust the original speed limit value. If the driver does not manually enter the speed limit value, the original speed limit value is maintained.

[0088] If the driver manually enters the speed limit value, the MMI system will send the value to the ATP system and send the first confirmation request to the ATP system. The ATP system will verify the train and the manually entered speed limit value. If the verification passes, it will send a second confirmation request to the MMI system; if the verification fails, the original speed limit value will be maintained.

[0089] When the MMI system receives the second confirmation request, it displays the manually entered speed limit value on the display interface for the driver to confirm the entered speed limit value again. If the driver does not confirm the entered speed limit value, the original speed limit value is maintained; if the driver modifies the entered speed limit value, the first confirmation request for the modified speed limit value is resent to the ATP system; if the driver confirms the entered speed limit value, the ATP system updates the original speed limit value to the speed limit value entered by the driver, that is, the ATP system uses the new speed limit value.
