[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0024] All actions involving the acquisition of signal information or data in this application are carried out in accordance with the relevant data protection laws and policies of the country where the application is located, and with the authorization granted by the owner of the relevant device.

[0025] Fully Automatic Operation (FAO) refers to an automated urban rail transit system that automatically completes train operation without human intervention through the integrated coordination and linkage control of train operation-related professional systems such as signaling, rolling stock, communication, platform screen doors, and integrated monitoring. FAO achieves automation and intelligence in train operation and emergency response. The Automatic Train Supervision (ATS), as the core unit of the signaling system, is responsible for monitoring and managing train operation and is a key system for automatically realizing train command and control and monitoring. The Integrated Supervisory Control System (ISCS) is the core integrated platform in the urban rail transit operation management system. It is mainly used for real-time centralized and unified monitoring of power equipment, environmental control equipment, fire alarms, platform screen door equipment, environmental parameters, etc., and has the ability to comprehensively link various systems and equipment in daily operation and emergency situations. A train section refers to the physical operating section connecting two adjacent station platforms. When severe water accumulation occurs in a section, it directly threatens train operation safety and operational order. In fully automated operation scenarios, in order to achieve a rapid response to water accumulation events in the train section, it is necessary to be able to automatically trigger and execute the corresponding emergency response procedures for water accumulation in the train section to ensure the safe operation of the train.

[0026] Currently, the handling of water accumulation in train sections mainly focuses on basic monitoring of water accumulation and post-event handling relying on human experience. There is a significant lack of automation and collaborative linkage. The overall level of automation and intelligence in handling the situation urgently needs to be improved, resulting in long emergency response links, poor timeliness of handling, and difficulty in real-time and accurate identification and interception of specific trains about to enter the affected section.

[0027] In response to this, and considering the current state of urban rail transit operations, this application provides a method for handling water accumulation in train sections. The aim is to achieve fully automated and coordinated closed-loop control from water accumulation warning to train impoundment in water accumulation scenarios, thereby improving the response speed and control accuracy of emergency response.

[0028] Figure 1 This is one of the flowcharts illustrating the method for handling water accumulation in train sections provided by the present invention.

[0029] It should be noted that the method provided in this application can be applied to various rail transit scenarios, including but not limited to urban rail transit systems such as subways, light rail, trams, intercity railways, and underground railway tunnel sections. The following explanation uses water accumulation treatment in a subway scenario as an example to illustrate the method provided in this application.

[0030] Furthermore, the method provided in this application can also be extended to other scenarios that require automated emergency response to abnormal conditions in a section, such as emergency linkage scenarios such as section fire, section obstacle intrusion, and section equipment failure. The corresponding automated response function can be achieved by adjusting the type of section status identifier and linkage strategy. This embodiment does not specifically limit this.

[0031] The method provided in this application can be applied to a train section water accumulation control system. This system employs a multi-system collaborative design architecture, thereby achieving fully automated handling from water accumulation monitoring to train impoundment. Specifically, the system comprises three main components: an integrated monitoring system, a train automatic monitoring system, and a Vehicle On-Board Controller (VOBC) for each train. These systems interact and coordinate through standardized interfaces, supporting highly reliable and real-time deployment. This forms a complete closed-loop intelligent emergency response process, including water accumulation monitoring, state transitions, coordinated decision-making, train selection, command issuance, and train impoundment execution, enabling automatic collaborative operation in subway section water accumulation emergency scenarios.

[0032] The integrated monitoring system is responsible for real-time monitoring of water accumulation in the section. When a high water level warning is issued, it acquires the location of the water accumulation and sends the location information and water accumulation status to the automatic train monitoring system. The automatic train monitoring system, as the core unit of the signaling system, is responsible for monitoring and managing train operation and is a key system for automatically realizing train command and control and monitoring. This automatic train monitoring system includes at least an integrated monitoring interface, a linkage control module, a train control module, and a train controller interface, as well as components such as a control and display terminal, which are not specifically limited in this embodiment. The integrated monitoring interface receives the water accumulation location and status information sent by the integrated monitoring system and converts it into a logical status identifier for water accumulation that can be recognized internally by the automatic train monitoring system according to predetermined conversion rules. The linkage control module receives and parses the logical status identifier for water accumulation in real time. When water accumulation conditions are detected, it searches for the associated detaining station based on the preset section configuration in the cache, automatically issues a detaining command, and simultaneously generates alarm information to be forwarded to the control and display terminal for display. The train control module receives platform arrest commands, updates the platform arrest information to the overall platform command management cache, and periodically polls train information at preset intervals to determine the target train and generate automatic train operation command data packets. The train controller interface converts the automatic train operation commands into standard automatic train operation information frames and sends them to the onboard controller of the target train at preset intervals. The control and display terminal displays train operation status, alarm information, and other information to staff. The onboard controller, or onboard train controller system, is the control equipment installed on each train. It is responsible for receiving control commands from the automatic train monitoring system and executing corresponding train control operations, including arresting trains at designated platforms.

[0033] It should be noted that the method provided in this application is implemented by the automatic train monitoring system.

[0034] like Figure 1 As shown, the method includes steps 110, 120, 130 and 140.

[0035] Step 110: Obtain the logical status identifier of water accumulation in the target interval.

[0036] In this embodiment, the target section refers to a train section, such as a subway section, that requires monitoring and handling of water accumulation. A train section is a physical operating segment connecting two adjacent station platforms. When severe water accumulation occurs in this section, it directly threatens train operation safety and operational order. The target section can be any section on the line that needs to be monitored, such as the upstream section between station A and station B, or the downstream section between station B and station C.

[0037] The section water accumulation logical status identifier is a logical identifier used within the Automatic Train Monitoring System (ATMS) to characterize the water accumulation status of a target section. This identifier can indicate whether a water accumulation warning has occurred in the target section, and can even identify the alarm level. The alarm level information here marks the emergency response level to which the section water accumulation event belongs, such as Level 0, Level A, Level B, and Level C alarms, etc., determined according to the internal classification rules for different alarm events within the train operation system. In one possible implementation, the section water accumulation logical status identifier can be the status information of a section water accumulation indicator light within the AMS. It should be noted that the section water accumulation indicator light is not a physical hardware device, but a logical object in the station data storage structure of the AMS, and its status value indicates whether a water accumulation warning has occurred in the associated section and the alarm level.

[0038] Optionally, the automatic train monitoring system can obtain the logical status identifier of water accumulation in the target section. The specific implementation methods may include, but are not limited to, the following: the automatic train monitoring system receives water accumulation monitoring data sent by the integrated monitoring system through the integrated monitoring interface and performs conversion processing to obtain the logical status identifier of water accumulation in the section; or, the automatic train monitoring system directly reads the real-time updated logical status identifier of water accumulation in the target section from the local database, etc. This embodiment does not specifically limit this.

[0039] Step 120: When the interval water accumulation logic status identifier indicates that the target interval is an interval where a water accumulation warning has occurred, find the physical operating interval associated with the interval water accumulation logic status identifier, and obtain the station platform to be detained according to the physical topology connection relationship of the physical operating interval.

[0040] In this embodiment, a physical operating section refers to a line section divided based on the physical connection relationship of stations, that is, a physical operating section that connects two adjacent station platforms. The automatic train monitoring system creates a station data storage structure corresponding to each physical operating section, and the logical status identifier of water accumulation in the section corresponds one-to-one with the physical operating section, forming a mapping relationship.

[0041] Physical topology connections refer to the physical connection attributes between a physical operating section and its adjacent stations, including the connection relationships between the physical operating section and its upstream and downstream adjacent stations. These physical topology connections are stored in the cache of the linkage control module of the automatic train monitoring system as part of the section configuration information. Through these physical topology connections, the upstream and downstream adjacent stations within a given physical operating section can be determined.

[0042] A platform to be detained refers to a platform where trains need to be detained when a flood warning is issued for a target section. The determination of a platform to be detained is based on the physical topology of the operating sections, and is typically the platform of the adjacent station upstream of the flooded section, to prevent trains from entering the flooded section and ensure operational safety. For example, if flooding occurs in the downstream section between station A and station B, the platform to be detained would be the platform of station A.

[0043] Optionally, the automatic train monitoring system can use the linkage control module to locate the physical operating section associated with the logical status identifier of water accumulation in the section and obtain the stations to be detained. Specific implementation steps include: The linkage control module receives and parses the section water accumulation logic status identifier forwarded by the integrated monitoring interface in real time, and detects whether the section water accumulation logic status identifier indicates that the target section is a section where a water accumulation warning has been issued. When the section water accumulation condition is triggered (that is, when the section water accumulation logic status identifier indicates that the target section is a section where a water accumulation warning has been issued), the linkage control module automatically triggers the water accumulation emergency linkage of the target section. Specifically, the linkage control module can find the physical operating section that matches the section water accumulation logic status identifier according to the mapping relationship between the section water accumulation logic status identifier and the physical operating section cached in its cached section configuration information (also known as the second configuration information), and obtain the station platform to be detained according to the physical topology connection relationship of the physical operating section cached in the second configuration information.

[0044] Step 130: Traverse the operating status information of each online train, and determine the target train among all the online trains based on the operating status information. The next stop of the target train is consistent with the platform to be detained.

[0045] Among them, online trains refer to trains currently running on the line, whose operating status information is monitored and managed in real time by the automatic train monitoring system. The number of online trains varies with operating hours and scheduling plans.

[0046] Operational status information refers to the current operational status data of online trains, including but not limited to the train's current location, direction of travel, speed, next stop, and train identification. This operational status information is stored in the train information management cache of the automatic train monitoring system and is updated in real time as the train operates.

[0047] A target train refers to a train that requires impoundment, whose next stop coincides with the platform of the station to be impounded, meaning the train is about to enter the flooded section. A target train can be one or more, depending on the current distribution and operational status of trains in service.

[0048] Optionally, the automatic train monitoring system can traverse the operating status information of each online train and determine the target train through the train control module. Specific implementation steps include: The train control module checks the operating status information of all currently online trains one by one, determining whether the next stop of each online train matches the platform of the train to be detained. If they match, the online train is identified as the target train. The traversal process can be implemented using various mechanisms such as timed polling and event triggering; this embodiment does not specifically limit the specific mechanisms used.

[0049] Step 140: Send a control message to the onboard controller of the target train according to the arrest command corresponding to the platform to be arrested. The control message is used to instruct the onboard controller to perform the arrest operation on the target train at the platform to be arrested.

[0050] Among them, the train arrest order is a control instruction generated by the automatic train monitoring system to instruct the train to stop at a designated platform and remain stationary.

[0051] The vehicle on-board controller (VOBC) is a control device installed on the train. It is responsible for receiving control commands from the automatic train monitoring system and executing corresponding train control operations. The VOBC and the automatic train monitoring system exchange data via a wireless communication network.

[0052] Control messages are communication data packets transmitted between the Automatic Train Monitoring System (ATMS) and the onboard controller. They contain key information such as the platform identifier of the station to be detained, the next stop identifier of the target train, and the detention command, and are used to convey the detention control instruction to the onboard controller.

[0053] Optionally, the automatic train monitoring system can send control messages to the onboard controller of the target train according to the train control module and train controller interface based on the train arrest command. Specific implementation steps may include: The train control module generates an automatic train operation command data packet for the target train based on the arrest command corresponding to the platform to be arrested, and sends it to the train controller interface.

[0054] After receiving the automatic train operation command, the train controller interface converts the command into a control message and sends it to the onboard controller of the target train via the communication interface. Upon receiving the control message, the onboard controller parses the detaining command and platform information, and executes the detaining operation when the target train arrives at the platform, preventing the train from entering the flooded section.

[0055] The method provided in this embodiment obtains the logical status identifier of water accumulation in the target section through the automatic train monitoring system. When a water accumulation warning is detected, it automatically searches for the associated physical operating section and determines the platform to be detained based on the physical topology connection relationship. It then traverses the online trains to determine the target train and sends a detention control message to the on-board controller of the target train. This achieves automatic collaborative linkage in the emergency scenario of water accumulation in the section, significantly improving the response speed, control accuracy and automation level of emergency response. The entire process from water accumulation monitoring to detention execution can be completed without manual intervention, enhancing operational safety and control reliability, and effectively ensuring the safe operation of trains in the event of water accumulation in the section.

[0056] In some embodiments, the step of obtaining the interval water accumulation logic status identifier of the target interval in step 110 specifically includes: Step 111: Receive water accumulation monitoring data of the target area sent by the integrated monitoring system; the water accumulation monitoring data includes water accumulation location information and water accumulation status information.

[0057] Optionally, the integrated monitoring interface receives water accumulation monitoring data for the target area sent by the integrated monitoring system.

[0058] The integrated monitoring interface is an interface module in the automatic train monitoring system used for data interaction with the integrated monitoring system. It is responsible for receiving information on the location and status of water accumulation in the section sent by the integrated monitoring system.

[0059] The integrated monitoring system is the core platform in the urban rail transit operation and management system. It is primarily used for real-time centralized monitoring of power equipment, environmental control equipment, fire alarms, platform screen door equipment, environmental parameters, etc., and possesses integrated linkage capabilities between various systems and equipment in daily operation and emergency situations. The integrated monitoring system collects water accumulation data in real time through water accumulation sensors deployed in each section. When a high water level warning is issued for a section, the integrated monitoring system obtains the location of the water accumulation, generates water accumulation monitoring data for each section, and sends it to the train automatic monitoring system.

[0060] Waterlogging monitoring data refers to the data collected and transmitted by the integrated monitoring system regarding the waterlogging situation in the target area, including waterlogging location information and waterlogging status information. The waterlogging location information identifies the specific location where waterlogging occurs, and can be a description of the exact location within the area; the waterlogging status information characterizes the severity of the waterlogging.

[0061] Step 112: Based on the first configuration information configured in the integrated monitoring interface of the automatic train monitoring system, the water accumulation location information and the water accumulation status information, the logical status identifier of the water accumulation in the section is obtained by matching.

[0062] Optionally, the integrated monitoring interface converts the water accumulation location information and water accumulation status information into a logical status identifier for water accumulation in the section that can be recognized within the automatic train monitoring system, according to the conversion rules in the pre-configured first configuration information.

[0063] The first configuration information consists of data conversion rules pre-configured in the integrated monitoring interface, including the matching relationship between water accumulation location information, water accumulation status information, and interval water accumulation logical status identifiers. This first configuration information is the core data configuration file of the integrated monitoring interface, used to achieve standardization and automatic mapping of data from multiple systems.

[0064] For example, when the logical state of water accumulation in a section is identified as the state of the water accumulation indicator light, the matching relationship in the first configuration information can refer to the correspondence between the water accumulation location and state sent by the integrated monitoring system and the water accumulation indicator light within the train automatic monitoring system. This matching relationship is pre-configured with a mapping table between each section identifier in the integrated monitoring system and the corresponding water accumulation indicator light in the train automatic monitoring system, as well as conversion rules between different water accumulation state values ​​and the state of the water accumulation indicator light.

[0065] In addition, the integrated monitoring interface can forward the matched interval water accumulation logic status identifier to the linkage control module to trigger the emergency linkage response process.

[0066] The method provided in this embodiment receives water accumulation monitoring data sent by the integrated monitoring system through the integrated monitoring interface, and realizes the standardized conversion of multi-system data according to the pre-configured first configuration information, completes the automatic matching of the logical status identifier of water accumulation in the interval, realizes the standardization and automatic mapping of multi-system data, provides an accurate data foundation for emergency response, effectively solves the problem of inconsistent data formats between different systems, and improves the efficiency and reliability of inter-system collaboration.

[0067] In some embodiments, step 120, which involves finding the physical operating section associated with the interval water accumulation logic status identifier and obtaining the station platform to be detained based on the physical topology connection relationship of the physical operating section, specifically includes: Step 121: Based on the second configuration information cached in the linkage control module of the train automatic monitoring system, find the physical operating section identifier that matches the section water accumulation logic status identifier, and obtain the physical operating section based on the physical operating section identifier.

[0068] Optionally, the linkage control module searches for a physical operating interval identifier that matches the interval water accumulation logic status identifier based on the second configuration information preset in its cache, and obtains the corresponding physical operating interval based on the physical operating interval identifier.

[0069] Among them, the linkage control module is the core module of the train automatic monitoring system responsible for realizing the emergency linkage control function. It receives and parses the section water accumulation logic status identifier forwarded by the integrated monitoring interface in real time. When the section water accumulation condition is detected, it automatically executes the section water accumulation emergency linkage process.

[0070] The second configuration information consists of pre-cached section configuration data in the linkage control module. This includes the matching relationship between the section water accumulation logic status identifier and the physical operating section identifier, as well as the physical topology connection relationship of the physical operating section. The second configuration information is based on the pre-divided and configured line section information according to the station's physical connection relationship, creating a station data storage structure corresponding to each section.

[0071] The physical operating zone identifier is an identifier used to uniquely identify a certain physical operating zone. It corresponds one-to-one with the logical status identifier of the zone water accumulation, forming a mapping relationship.

[0072] Step 122: Based on the physical operating range, find the physical topology connection relationship of the physical operating range in the second configuration information.

[0073] Optionally, after obtaining the physical operating section, the linkage control module further searches for the physical topology connection relationship of the physical operating section in the second configuration information to determine the connection attribute between the section and the adjacent station.

[0074] The physical topology connection relationship includes at least the connection attributes between the physical operating section and its upstream adjacent stations, and may also include other topology information such as the connection attributes between the physical operating section and its downstream adjacent stations, section length information, and speed limit information.

[0075] Step 123: Based on the physical topology connection relationship, obtain the upstream adjacent station identifier in the physical operating section.

[0076] Optionally, the linkage control module obtains the upstream adjacent station identifier of the physical operating section based on the connection attributes recorded in the physical topology connection relationship.

[0077] The upstream adjacent station identifier refers to the identifier of the station located upstream of the physical operating section and directly adjacent to that section. Depending on the train's direction of travel, the upstream adjacent station is the station the train must pass through before entering the physical operating section. For example, for a southbound section from station A to station B, if the train departs from station A and travels towards station B, then station A is the upstream adjacent station for that section.

[0078] Step 124: If the target station corresponding to the upstream adjacent station identifier is marked as being in an automatic detaining state, then the target station is determined as the detaining station platform.

[0079] Optionally, the linkage control module determines whether the target station corresponding to the upstream adjacent station identifier is marked as being allowed to automatically detain the train. If the platform is allowed to automatically detain the train, the target station is identified as the platform to be detained, and a detaining command is automatically issued.

[0080] The "Allow Automatic Detention Status" is a station attribute flag pre-configured in the section configuration information, used to identify whether a station allows the Automatic Train Monitoring System (ATS) to automatically perform a detention operation. The setting of this attribute flag takes into account factors such as station operating conditions, platform capacity, and transfer demand.

[0081] In addition, after identifying the platform to be detained, the linkage control module can forward the platform's detention order to the train control module to trigger the train screening and command issuance process.

[0082] The method provided in this embodiment realizes intelligent linkage decision-making based on topology configuration through the second configuration information cached in the linkage control module. It can automatically find the physical operating section associated with the logical status identifier of water accumulation in the section, and intelligently determine the station platform to be detained according to the physical topology connection relationship. This realizes rapid and accurate response in the emergency scenario of water accumulation in the section, without the need for manual search and judgment, and significantly improves the efficiency of emergency response and the accuracy of decision-making.

[0083] In some embodiments, step 130, which involves traversing the operating status information of each online train and determining the target train among all the online trains based on the operating status information, specifically includes: Step 131: In the overall platform command management cache, mark the detaining status parameter corresponding to the platform to be detained as valid, and obtain the updated overall platform command management cache.

[0084] Optionally, the train control module receives the platform deactivation command forwarded by the linkage control module and executes the following steps: Based on the platform information in the received platform impoundment command, the impoundment status parameters corresponding to the platforms to be impounded in the overall platform command management cache are marked as valid.

[0085] The overall platform command management cache is a data cache structure maintained in the train control module of the automatic train monitoring system. It is used to store and manage the command status information of each platform. The overall platform command management cache contains command status records for all platforms on the line, with one record corresponding to each platform.

[0086] The vehicle impoundment status parameter is a parameter field in the overall station command management cache used to identify the status of a vehicle impoundment command for a specific station. The vehicle impoundment status parameter includes a valid status and an invalid status. A valid status indicates that the station currently needs to perform a vehicle impoundment operation, while an invalid status indicates that the station currently does not need to perform a vehicle impoundment operation.

[0087] Step 132: Periodically poll the online train's operating status information in the train information cache according to a preset cycle.

[0088] Optionally, the train control module periodically polls the train information cache for the operating status information of each online train according to a preset cycle, so as to keep track of the operating status of each train in real time.

[0089] The preset period is a pre-configured time interval for polling train status. Its setting needs to take into account both system response speed and computing resource consumption. It can be configured according to actual operational needs, such as 1 second.

[0090] The train information cache is a data cache structure in the automatic train monitoring system used to store the operating status information of each online train, including the train's current position, direction of travel, speed, next stop, train identification, and other information. The data in the train information cache is updated in real time as the train is running.

[0091] Step 133, for each online train, perform the following steps: Based on the online train's operating status information, the next stop of the online train is obtained; If the vehicle impoundment status parameter corresponding to the next stop is found to be valid in the updated overall platform command management cache, and the next stop is consistent with the platform to be impounded, then the online train is determined to be the target train.

[0092] Optionally, the train control module extracts the next stop information from the operating status information of each online train to determine whether the train is about to enter a flooded area. The next stop information can be in the form of platform identification, platform name, etc.

[0093] After obtaining the next stop of the online train, the train control module compares the next stop of the online train with the updated overall platform command management cache. If the next stop is marked as valid in the overall platform command management cache and the next stop is consistent with the platform to be detained, then the online train is identified as the target train.

[0094] The method provided in this embodiment manages the detaining status of each platform uniformly through the command management cache of all platforms, and polls the running status information of each online train at preset cycles. It can identify the target train that needs to be detained in real time and accurately, realize the refined management and precise control of online trains, and ensure that the detaining command can be accurately issued to the train that is about to enter the flooded section, thereby improving the timeliness and accuracy of emergency response.

[0095] In some embodiments, step 140, which involves sending a control message to the onboard controller of the target train according to the detaining command corresponding to the platform to be detained, specifically includes: Step 141: Update the platform identifier of the platform to be detained to the platform detaining field in the automatic train operation control command information of the target train.

[0096] Optionally, after determining the target train, the train control module updates the platform identifier of the platform to be detained to the platform detention field in the automatic train operation control command information of the target train.

[0097] The Automatic Train Operation (ATO) control command information is a command data structure generated by the Automatic Train Monitoring System (ATMS) to control the automatic operation of trains. ATO control command information includes key information fields such as the platform to stop field, the next stopping platform field, and the operation mode field.

[0098] Step 142: Generate a train automatic operation command data packet for the target train based on the updated train automatic operation control command information; the train automatic operation command data packet includes at least the platform identifier of the station to be detained and the next stop identifier of the target train.

[0099] Optionally, the train control module polls the train information management cache, generates a train automatic operation command data packet for the target train based on the updated train automatic operation control command information, and sends the train automatic operation command data packet to the train controller interface.

[0100] Among them, the Automatic Train Operation Command Data Packet, or ATO Command Data Packet, is a data packet generated based on the updated Automatic Train Operation Control Command Information. It contains key information such as the platform to be stopped and the next stopping platform, and is used to transmit the train stopping control instruction to the on-board controller.

[0101] Step 143: Update the train automatic operation command frame of the target train in the train controller interface cache of the train automatic monitoring system according to the train automatic operation command data packet.

[0102] Optionally, after receiving the automatic train operation command data packet sent by the train control module, the train controller interface updates the automatic train operation command frame of the target train in the train information cache of this module.

[0103] The train controller interface is the interface module in the automatic train monitoring system used for data interaction with the onboard controller. The automatic train operation command frame is a data frame structure maintained internally by the train controller interface, used to store the automatic train operation command information to be sent to the onboard controller.

[0104] Step 144: According to the communication protocol between the Automatic Train Monitoring System and the Onboard Controller, the updated Automatic Train Operation Command Frame is packaged into a standard Automatic Train Operation Information Frame; the standard Automatic Train Operation Information Frame includes at least the platform identifier of the station to be detained, the next stop identifier of the target train, and the detention command.

[0105] Optionally, the train controller interface packages the updated automatic train operation command frame into a standard automatic train operation information frame according to the communication protocol between the automatic train monitoring system and the on-board controller.

[0106] Among them, the communication protocol refers to the pre-agreed data communication standard between the automatic train monitoring system and the on-board controller, that is, the protocol between the automatic train monitoring system and the on-board train controller system.

[0107] A standard Automatic Train Operation (ATO) information frame includes key information such as the next stopping platform, the arrest command, and the arrest platform. The arrest command includes status indicators such as arrest valid, arrest invalid, and default value. When the arrest command is valid, the onboard controller will execute the arrest operation upon reaching the arrest platform.

[0108] Step 145: Encapsulate the standard automatic train operation information frame into the control message, and send the control message to the on-board controller according to a preset sending cycle until a detaining release command is received for the detaining station platform.

[0109] Optionally, the train controller interface encapsulates standard automatic train operation information frames into control messages and periodically sends the control messages to the onboard controller of the target train according to a preset sending cycle.

[0110] The preset sending period is a pre-configured control message sending time interval. Its setting needs to take into account both communication reliability and network bandwidth consumption, and can be configured according to actual communication conditions.

[0111] The train arrest release command is a control command generated by the Automatic Train Monitoring System (ATS) after the water accumulation in the section has been cleared, used to release the train arrest status at the platform. Before receiving the arrest release command, the train controller interface continuously sends control messages to the onboard controller according to a preset sending cycle to ensure that the arrest command remains valid.

[0112] In addition, after receiving information about train impoundment, the onboard controller will execute the impoundment operation at the relevant platform to prevent the train from entering the flooded area and ensure driving safety.

[0113] The method provided in this embodiment accurately and reliably transmits the train impoundment command from the Automatic Train Monitoring System to the onboard controller of the target train through a complete command generation and issuance process. This achieves efficient collaboration between the Automatic Train Monitoring System and the onboard controller, ensuring the timely execution of the impoundment operation and effectively protecting train safety in waterlogged sections.

[0114] In some embodiments, the method further includes the following steps: When the interval water accumulation logic status identifier indicates that the target interval is an interval where a water accumulation warning has occurred, the interval location information, water accumulation location information, water accumulation status information and alarm level of the target interval are obtained according to the interval water accumulation logic status identifier; An alarm message is generated based on the interval location information, the water accumulation location information, the water accumulation status information, and the alarm level; Based on the alarm level and the interval location information, determine the alarm display mode corresponding to the target interval; According to the alarm display mode, the alarm information is displayed.

[0115] Optionally, when the linkage control module detects that the interval water accumulation condition has been triggered, it can also obtain the interval location information, water accumulation location information, water accumulation status information and alarm level of the target interval based on the interval water accumulation logic status identifier.

[0116] The section location information identifies the specific location of the target section within the line; the alarm level information indicates the emergency response level to which the water accumulation event in the section belongs, such as Level 0 alarm, Level A alarm, Level B alarm, and Level C alarm. Different alarm levels correspond to different emergency response measures and alarm display methods, with severe alarm levels requiring more urgent handling measures.

[0117] Subsequently, the linkage control module can obtain the alarm display mode corresponding to the target interval based on the association mapping relationship between the alarm level and interval location information and the alarm display mode.

[0118] The alarm display mode refers to how alarm information is displayed on the control terminal, including different display formats such as pop-up display, audible alarm, color coding, and flashing display. Different alarm levels can correspond to different alarm display modes, so that staff can quickly identify the urgency of the alarm.

[0119] For example, a red highlighted pop-up window with an audible alarm can be used for Class A alarms; a yellow pop-up window can be used for Class B alarms. The location of the alarm zone can also influence the choice of display mode; for instance, alarms in key zones can be displayed in a more prominent way.

[0120] After obtaining the alarm display mode corresponding to the target section, the linkage control module forwards the generated alarm information to the control and display terminal. The control and display terminal then displays the alarm information according to the determined alarm display mode to notify staff that a water accumulation event has occurred in the section associated with the water accumulation logic status identifier. Staff can understand the details of the water accumulation event based on the alarm information and take further action as needed.

[0121] The control and display terminal is the human-machine interface of the automatic train monitoring system, used to display train operating status, alarm information, and other information to staff. Control and display terminals are typically deployed in the control center or station control room for use by dispatchers and operations management personnel.

[0122] The method provided in this embodiment, while performing automatic vehicle impoundment linkage, determines differentiated alarm display modes based on alarm level and interval location information, enabling staff to intuitively and quickly identify the urgency of the alarm and the specific location of the water accumulation event, thereby taking targeted and appropriate measures and improving the accuracy and timeliness of emergency response.

[0123] The following specific examples further illustrate the method for dealing with water accumulation in train sections provided by the present invention.

[0124] Figure 2 This is a schematic diagram of an exemplary subway line provided by the present invention; Figure 3 This is the second flowchart of the method for dealing with water accumulation in train sections provided by the present invention.

[0125] like Figure 2 As shown, taking a certain subway line as an example, its physical operating section includes the southbound section from station A to station B and the aforementioned section from station B to station A. Figure 3 As shown, if severe water accumulation occurs in the downstream section from station A to station B, the specific methods provided in this application include: First, the integrated monitoring system monitors the water accumulation status of each section in real time. When a high water level warning is detected by the water accumulation sensor deployed in the downlink section from station A to station B, the water accumulation monitoring data, including the section location information and the water accumulation status of the section, is sent to the integrated monitoring interface of the train automatic monitoring system.

[0126] Secondly, the integrated monitoring interface converts the water accumulation location and status information sent by the integrated monitoring system into the water accumulation logic status identifier of the section within the train automatic monitoring system according to the predetermined conversion rules configured internally, namely the conversion rules in the first configuration information, and forwards the water accumulation logic status identifier of the section to the linkage control module.

[0127] Secondly, the linkage control module receives and parses the section water accumulation logic status identifier in real time. If the section water accumulation condition is triggered, that is, if the section water accumulation logic status identifier indicates that the downlink section from station A to station B is a section with a water accumulation warning, the linkage control module executes the following process: generating alarm information containing detailed information such as section location information, water accumulation location information, water accumulation status information, and alarm level, and forwarding it to the control display terminal for alarm display, prompting staff that a section water accumulation event has occurred in the downlink section from station A to station B. At the same time, the linkage control module automatically triggers the section water accumulation emergency linkage. Specifically, according to the preset section configuration in the second configuration information, it finds the physical operating section associated with the downlink section from station A to station B, and determines the upstream adjacent station of this section as platform A1 based on the physical topology connection relationship. Since platform A1 is marked as allowing automatic train arrest, the linkage control module automatically issues a train arrest command to platform A1 and forwards the train arrest command to the train control module.

[0128] Then, after receiving the train arrest command, the train control module updates the arrest status parameters of platform A1 to a valid status and periodically polls the running status information of each online train in the train information cache according to a preset cycle. Assuming that the next stop of train T001 is platform A1, the train control module determines that train T001 is the target train, automatically updates the arrest platform information in the train automatic operation control command information in the train cache to platform A1, and generates a train automatic operation command data packet to send to the train controller interface.

[0129] Finally, after receiving the automatic train operation command, the train controller interface updates the automatic train operation command frame in its train information cache. Based on the communication protocol between the automatic train monitoring system and the onboard controller, it packages the command into a standard automatic train operation information frame, including the next stopping platform being platform A1, the arrest command being valid, and the arresting platform being platform A1. The train controller interface sends the automatic train operation information frame to the onboard controller of train T001 at a preset cycle. Upon receiving the arrest information, the onboard controller executes the arrest operation at platform A1, preventing train T001 from entering the flooded section between stations A and B on the downhill side, thus ensuring train safety.

[0130] This example demonstrates that the method provided in this application can achieve automatic coordinated linkage in emergency scenarios of water accumulation in the area. The entire process, from the detection of water accumulation warning by the integrated monitoring system to the execution of vehicle impoundment by the vehicle controller, requires no manual intervention, which significantly improves the automation level of emergency response and enhances operational safety and control reliability.

Figure 4 As shown, the system includes an integrated monitoring interface 410, a linkage control module 420, a train control module 430, and a train controller interface 440. The integrated monitoring interface 410 is used to obtain the logical status identifier of water accumulation in the target area; The linkage control module 420 is used to find the physical operating section associated with the water accumulation logic status indicator when the target section indicates that the water accumulation warning has occurred, and to obtain the station platform to be detained and issue a vehicle detention command according to the physical topology connection relationship of the physical operating section. The train control module 430 is used to traverse the operating status information of each online train, and determine the target train among all the online trains based on the operating status information. The next stop of the target train is consistent with the platform to be detained. The train controller interface 440 is used to send a control message to the onboard controller of the target train according to the arrest command corresponding to the platform to be arrested. The control message is used to instruct the onboard controller to perform an arrest operation on the target train at the platform to be arrested.
