Description

Technical Field

[0001] This invention relates to the field of rail transit technology, and in particular to a method, device and system for emergency control of rail transit disaster recovery. Background Technology

[0002] The International Association of Public Transport (UITP) classifies the Grade of Automation (GoA) of train operations into five levels based on the allocation of responsibilities between operators and systems for the basic functions of train operation: GoA0, GoA1, GoA2, GoA3, and GoA4.

[0003] Currently, fully automatic operation (FAO) systems with automation levels reaching GoA3 and GoA4 are the main development trend. In FAO systems, there is no driver on the train; the onboard equipment calculates the automatic operation curve based on information such as movement authorization and speed limit received from ground signaling equipment, and automatically controls the train's operation.

[0004] In the event of internal equipment failure or external hazards, the driver assumes some of the emergency response duties in manned mode. However, the onboard system within the FAO system cannot fully replace these driver functions. Although control commands can be monitored and issued from the control center, external threats may cause simultaneous communication failures between the train and the ground. In such cases, control center commands become ineffective, and the operating train cannot perform safe operations to ensure passenger safety. Summary of the Invention

[0016] According to the rail transit disaster recovery emergency control method provided by the present invention, if the control center issues an abnormal instruction to the existing on-board signaling equipment, or the existing on-board signaling equipment malfunctions, the method controls the current train to perform emergency operations based on the train status, including:

[0017] If the existing onboard signaling equipment malfunctions, but the emergency communication module communicates normally with the control center, the control center remotely controls the current train to perform emergency operations.

[0018] The rail transit disaster recovery and emergency control method provided by the present invention further includes:

[0019] If the control center issues a normal instruction to the existing onboard signaling equipment and the existing onboard signaling equipment does not malfunction, the train status is sent to the control center so that the control center, the current train, and other trains can network together to monitor the disaster.

[0020] The present invention also provides a rail transit disaster recovery emergency control device, comprising:

[0021] The information acquisition unit is used to acquire current train environmental information, fault information of existing onboard signaling equipment, and disaster alarm information;

[0022] A status determination unit is used to determine the current train status based on the environmental information, the fault information, and the disaster alarm information.

[0041] Figure 4This is a schematic diagram of the structure of the electronic device provided by the present invention. Detailed Implementation

[0042] 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.

[0043] Any system is susceptible to failure, and public transportation faces not only equipment malfunctions but also external threats such as natural disasters (e.g., floods), man-made disasters (e.g., fires), and vandalism (e.g., obstacles, track damage).

[0044] In the event of an external threat, communication between the train and the ground may fail simultaneously. In this case, the control center's instructions will be ineffective, and the operating train will be unable to perform safe operations to ensure the safety of passengers.

[0045] Based on the above considerations, and in order to cope with emergencies during train operation, minimize passenger loss of life and property, and improve the reliability of train operation, the inventive concept of this invention is to add an independent, miniaturized, and highly reliable disaster recovery and emergency control system to the train's onboard equipment. This system can monitor the current train's environmental information, fault information, and disaster alarm information, and determine the train's status based on these information. If the control center issues abnormal instructions to the existing onboard signaling equipment, or if the existing onboard signaling equipment malfunctions, the system will control the current train to perform emergency operations based on the train's status. This can prevent situations where a single point of failure in the existing signaling system prevents the operating train and passengers from evacuating to a safe area, thereby reducing passenger loss of life and property and improving the reliability of train operation.

[0046] Based on the above-mentioned inventive concept, the present invention provides a method, device and system for emergency control of rail transit disaster recovery, which is applied to emergency recovery scenarios in the operation of rail transit to improve the reliability of train operation.

[0047] The technical solution of the present invention will now be described in detail with reference to the accompanying drawings. Figure 1This is one of the flowcharts illustrating the rail transit disaster recovery and emergency control method provided by the present invention. The executing entity for each step in this method can be a rail transit disaster recovery and emergency control device. This device can be implemented through software and / or hardware, and can be integrated into an electronic device. The electronic device can be a terminal device (such as a smartphone, personal computer, in-vehicle equipment, etc.), a server (such as a local server or cloud server, or a server cluster, etc.), a processor, or a chip, etc. Figure 1 As shown, the method may include the following steps:

[0048] Step 110: Obtain the current environmental information of the train, including fault information of the onboard signaling equipment and disaster alarm information;

[0049] Step 120: Determine the current train status based on environmental information, fault information, and disaster alarm information;

[0050] Step 130: If the control center issues an abnormal instruction to the existing onboard signaling equipment, or if the existing onboard signaling equipment malfunctions, the current train will perform an emergency operation based on the train status control.

[0051] Specifically, the current train is the one that requires disaster recovery and emergency control. The environmental information of the current train can include internal and external environmental information. Internal environmental information can include the train's internal temperature, internal humidity, personnel, and speed, etc.; external environmental information can include the train's external temperature, external humidity, surrounding environment, and whether there are obstacles, etc.

[0052] Furthermore, the current environmental information of the train can be obtained through environmental monitoring sensors. These sensors may include internal and external environmental monitoring sensor groups. The internal environmental monitoring sensor group includes, but is not limited to, temperature sensors, humidity sensors, human body sensors, and speed sensors; the external environmental monitoring sensor group includes, but is not limited to, temperature sensors, water immersion sensors, vibration sensors, video acquisition equipment, and radar equipment.

[0053] Existing onboard signaling equipment refers to the train control signaling equipment already configured on the current train. The rail transit disaster recovery emergency control system provided in this embodiment of the invention can serve as a backup system for the existing train control system. It can establish wireless communication connections with the control center and other trains through the emergency communication module, and monitor the fault information and disaster alarm information of the existing onboard signaling equipment through the control center.

[0054] The disaster alarm information here may include disaster alarm information from the control center, as well as disaster alarm information from other trains.

[0055] Once the current environmental information of the train is obtained, including fault information from onboard signaling equipment and disaster alarm information, the train's current status can be determined comprehensively based on this information. The train status can include the condition of the train or track, as well as the condition of the surrounding environment. For example, the train status may include train equipment malfunction, foreign object intrusion, track abnormalities, abnormal internal / external temperature, abnormal internal humidity, abnormal train vibration, water immersion, earthquake disaster, flooding in a certain area, or fire in a certain area.

[0056] In related technologies, when a single point of failure occurs in the existing signaling system, that is, when the control center issues abnormal instructions to the existing onboard signaling equipment, or when the existing onboard signaling equipment malfunctions, the control center instructions are invalid, and the operating train cannot perform safe operations to ensure passenger safety.

[0057] In this embodiment, the current train can understand its own train status in real time, and can then control the current train to perform emergency operations based on the train status. This control can be fully automatic control, remote control from a control center, or control by existing onboard signaling equipment; this embodiment of the invention does not specifically limit this.

[0058] The method provided in this invention determines the train status based on environmental information, fault information, and disaster alarm information. If the control center issues abnormal instructions to the existing onboard signaling equipment, or if the existing onboard signaling equipment malfunctions, the method controls the current train to perform emergency operations based on the train status. This avoids situations where a single point of failure in the existing signaling system prevents operating trains and passengers from evacuating to a safe area, thereby reducing passenger loss of life and property and improving the reliability of train operations.

[0059] Based on the above embodiments, if the control center issues abnormal instructions to the existing on-board signaling equipment, or if the existing on-board signaling equipment malfunctions, the current train will perform emergency operations based on the train status control. Specifically, step 130 includes:

[0060] Step 131: If the control center issues an abnormal instruction to the existing onboard signaling equipment, but the existing onboard signaling equipment has not malfunctioned, the emergency strategy is sent to the existing onboard signaling equipment so that the existing onboard signaling equipment can send a train control instruction based on the emergency strategy to control the current train to perform emergency operations; the emergency strategy is determined based on the current train status.

[0061] Specifically, if the control center issues an abnormal instruction to the existing onboard signaling equipment, but the existing onboard signaling equipment has not malfunctioned, it means that the existing onboard signaling equipment on the current train can control the train normally, but cannot receive control instructions from the control center. In this case, the emergency command mode is entered, that is, the backup system commands the existing onboard signaling equipment to perform emergency operations.

[0062] In this mode, the backup system can first determine an emergency strategy based on the current train status. This emergency strategy can be obtained through pre-set rules or a pre-trained strategy determination model; this embodiment of the invention does not specifically limit this. For example, the current train status can be input into a pre-trained strategy determination model to obtain the emergency strategy output by the model.

[0063] Emergency response strategies may include alarms, broadcasts, stopping and waiting, leaving the danger zone, evacuation to the nearest location, and platform evacuation.

[0064] Then, the emergency strategy can be sent to the existing vehicle signal equipment. After receiving the emergency strategy, the existing vehicle signal equipment will output vehicle control commands and start the emergency broadcast.

[0065] Considering that the existing vehicle signal equipment has more complete functions, in this embodiment, if the control center issues an abnormal command to the existing vehicle signal equipment, but the existing vehicle signal equipment has not malfunctioned, the backup system only provides emergency strategies and does not send vehicle control commands.

[0066] Based on the above embodiments, if the control center issues abnormal instructions to the existing on-board signaling equipment, or if the existing on-board signaling equipment malfunctions, the current train will perform emergency operations based on the train status control, i.e., step 130 includes:

[0067] Step 132: If the existing onboard signaling equipment malfunctions and the emergency communication module communicates abnormally with the control center, a train control command is sent based on the emergency strategy to control the current train to perform emergency operations. The emergency strategy is determined based on the current train status.

[0068] Specifically, if the existing vehicle-mounted signaling equipment malfunctions, it is necessary to further check whether the backup system and the control center are communicating abnormally. If the emergency communication module of the backup system is not communicating with the control center, it will enter the autonomous emergency mode, that is, the backup system will autonomously send vehicle control commands.

[0069] In this mode, the backup system sends train control commands according to the emergency strategy to control the current train to perform emergency operations, such as automatically activating emergency broadcasts or automatically controlling the activation of the train's emergency escape equipment; when necessary, it can also automatically control the train to leave the danger zone at a low speed based on video image information, radar monitoring information, and speed sensor information.

[0070] Based on the above embodiments, step 132, which involves sending a train control command based on an emergency strategy to control the current train to perform emergency operations, includes:

[0071] Train control commands are generated based on emergency strategies and sent to the train controller via a control converter, so that the train controller can control the current train to perform emergency operations.

[0072] Specifically, to further improve the reliability of this backup system, in autonomous emergency mode, a control converter sends train control commands to the train controller, enabling the train controller to control the current train to perform emergency operations. The control converter ensures that the system only outputs train control commands to the train controller when existing onboard signaling equipment fails or when control authorization is provided, thus enabling the train controller to control the current train to perform emergency operations.

[0073] Based on the above embodiments, if the control center issues abnormal instructions to the existing on-board signaling equipment, or if the existing on-board signaling equipment malfunctions, the current train will perform emergency operations based on the train status control, i.e., step 130 includes:

[0074] Step 133: If the existing onboard signaling equipment malfunctions, but the emergency communication module communicates normally with the control center, the control center will remotely control the current train to perform emergency operations.

[0075] Specifically, if the existing vehicle-mounted signal equipment malfunctions, but the emergency communication module communicates normally with the control center, the remote emergency mode will be activated.

[0076] In this mode, the control center operator can remotely control the train's emergency broadcast system and emergency escape system through this system; when necessary, the control center operator can perform remote driving operations through the system's video image information, radar monitoring information (obstacle detection), and speed sensor information.

[0077] Based on the above embodiments, the method further includes:

[0078] If the control center issues commands to the existing onboard signaling equipment normally and the existing onboard signaling equipment has not malfunctioned, the train status will be sent to the control center so that the control center, the current train, and other trains can network together to monitor the disaster.

[0079] Specifically, if the control center issues commands to the existing onboard signaling equipment normally and the existing onboard signaling equipment does not malfunction, it indicates that the main functions of the existing train control system are normal and can complete emergency command and control, and then enter the disaster monitoring mode.

[0080] In this mode, the train's status (including collected and monitored environmental information and alarm information) is sent to the control center, enabling the control center, the current train, and other trains to network for disaster monitoring and assisting control center personnel in issuing control commands. Here, "other trains" refers to other trains operating along the entire line that can wirelessly communicate with the current train. In this mode, the system only monitors and issues alarms; it does not output control commands or instructions.

[0081] The following describes the rail transit disaster recovery and emergency control device provided by the present invention. The rail transit disaster recovery and emergency control device described below and the rail transit disaster recovery and emergency control method described above can be referred to in correspondence.

[0082] Figure 2 This is a schematic diagram of the structure of the rail transit disaster recovery and emergency control device provided by the present invention, as shown below. Figure 2 As shown, the rail transit disaster recovery and emergency control device includes an information acquisition unit 210, a status determination unit 220, and an emergency control unit 230, wherein:

[0083] The information acquisition unit 210 is used to acquire the current environmental information of the train, fault information of existing on-board signaling equipment, and disaster alarm information.

[0084] The status determination unit 220 is used to determine the current train status based on environmental information, fault information, and disaster alarm information.

[0085] The emergency control unit 230 is used to control the current train to perform emergency operations based on the train status if the control center issues abnormal instructions to the existing on-board signaling equipment or if the existing on-board signaling equipment malfunctions.

[0086] The rail transit disaster recovery emergency control device provided in this invention determines the train status based on environmental information, fault information, and disaster alarm information. If the control center issues abnormal instructions to the existing onboard signaling equipment, or if the existing onboard signaling equipment malfunctions, the device controls the current train to perform emergency operations based on the train status. This avoids situations where a single point of failure in the existing signaling system prevents operating trains and passengers from evacuating to a safe area, thereby reducing passenger loss of life and property and improving the reliability of train operations.

[0087] Based on the above embodiments, the emergency control unit 230 is also used for:

[0088] If the control center issues an abnormal instruction to the existing onboard signaling equipment, but the existing onboard signaling equipment is not malfunctioning, an emergency strategy is sent to the existing onboard signaling equipment so that the existing onboard signaling equipment can send a train control instruction based on the emergency strategy to control the current train to perform emergency operations; the emergency strategy is determined based on the current train status.

[0089] Based on the above embodiments, the emergency control unit 230 is also used for:

[0090] If the existing onboard signaling equipment malfunctions and the emergency communication module fails to communicate with the control center, a train control command is sent based on the emergency strategy to control the current train to perform emergency operations. The emergency strategy is determined based on the current train status.

[0091] Based on the above embodiments, the emergency control unit 230 is also used for:

[0092] Based on the emergency strategy, a train control command is generated, and the train control command is sent to the train controller via the control converter, so that the train controller can control the current train to perform emergency operations.

[0093] Based on the above embodiments, the emergency control unit 230 is also used for:

[0094] If the existing onboard signaling equipment malfunctions, but the emergency communication module is communicating with the control center, the control center will remotely control the current train to perform emergency operations.

[0095] Based on the above embodiments, the rail transit disaster recovery and emergency control device further includes a disaster monitoring unit, used for:

[0096] If the control center issues instructions to the existing onboard signaling equipment normally, and the existing onboard signaling equipment does not malfunction, the train status is sent to the control center so that the control center, the current train, and other trains can network together to monitor disasters.

[0097] Based on the above embodiments, Figure 3 This is a schematic diagram of the structure of the rail transit disaster recovery and emergency control system provided by the present invention, as shown below. Figure 3 As shown, the rail transit disaster recovery and emergency control system includes:

[0098] Internal environment monitoring equipment 310 is used to collect information about the current internal environment of the train.

[0099] External environment monitoring equipment 320 is used to collect information about the current external environment of the train;

[0100] Emergency communication module 330 is used to establish wireless communication with the control center and other trains;

[0101] The emergency control module 340 is electrically connected to the internal environmental monitoring device 310, the external environmental monitoring device 320, and the emergency communication module 330, respectively. It is used to acquire fault information and disaster alarm information of the existing on-board signaling equipment, and determine the current train status based on the environmental information, the fault information, and the disaster alarm information. If the control center issues abnormal instructions to the existing on-board signaling equipment, or if the existing on-board signaling equipment malfunctions, it controls the current train to perform emergency operations based on the train status.

[0102] Specifically, the internal environment monitoring device 310 may be an internal environment monitoring sensor group, including but not limited to temperature sensors, humidity sensors, human body sensors, speed sensors, etc.

[0103] The external environment monitoring device 320 can be an external environment monitoring sensor group, including but not limited to temperature sensors, water immersion sensors, vibration sensors, video acquisition devices, radar devices, etc.

[0104] Emergency communication module 330 establishes wireless communication with the control center and other train emergency systems.

[0105] The emergency control module 340 may specifically include a situation awareness layer, an emergency strategy layer, and an emergency control layer.

[0106] The situation awareness layer acquires information from internal / external environmental monitoring sensor groups, train controller fault alarm information, onboard signal equipment fault alarm information, control center disaster alarm information, and other train disaster alarm information, and comprehensively judges the train status and disaster information. Examples include train equipment failure, foreign object intrusion, track abnormalities, abnormal internal / external temperature, abnormal internal humidity, abnormal train vibration, train flooding, earthquake disasters, floods in a certain area, and fires in a certain area.

[0107] The emergency strategy layer calculates emergency strategies based on information provided by the situation awareness layer, such as alarm, broadcast, stop and wait, leave the danger zone, evacuate to the nearest location, and evacuate from the platform.

[0108] In the emergency control layer, if the control center issues abnormal instructions to the existing onboard signaling equipment, or if the existing onboard signaling equipment malfunctions, the system will control the current train to perform emergency operations based on the train's status. These emergency operations may include emergency command mode, remote emergency mode, and autonomous emergency mode.

[0109] The rail transit disaster recovery and emergency control system provided in this invention determines the train status based on environmental information, fault information, and disaster alarm information. If the control center issues abnormal instructions to the existing onboard signaling equipment, or if the existing onboard signaling equipment malfunctions, the system controls the current train to perform emergency operations based on the train status. This avoids situations where a single point of failure in the existing signaling system prevents operating trains and passengers from evacuating to safe areas, thereby reducing passenger loss of life and property and improving the reliability of train operations.

[0110] Based on the above embodiments, the emergency control module 340 is also used for:

[0111] If the control center issues commands to the existing onboard signaling equipment normally and the existing onboard signaling equipment has not malfunctioned, the train status will be sent to the control center so that the control center, the current train, and other trains can network together to monitor the disaster.

[0112] Specifically, if the control center issues commands to the existing onboard signaling equipment normally and the existing onboard signaling equipment does not malfunction, it indicates that the main functions of the existing train control system are normal and can complete emergency command and control, and then enter the disaster monitoring mode.

[0113] In this mode, the train's status (including collected and monitored environmental information and alarm information) is sent to the control center, enabling the control center, the current train, and other trains to network for disaster monitoring and assisting control center personnel in issuing control commands. Here, "other trains" refers to other trains operating along the entire line that can wirelessly communicate with the current train. In this mode, the system only monitors and issues alarms; it does not output control commands or instructions.

[0114] The four operating modes of the rail transit disaster recovery and emergency control system are shown in Table 1. For example, if the control center issues an abnormal command to the existing onboard signaling equipment, but the existing onboard signaling equipment has not malfunctioned, the system enters the emergency command mode.

[0115] If the existing vehicle-mounted signal equipment malfunctions and the emergency communication module fails to communicate with the control center, it will enter the autonomous emergency mode.

[0116] If the existing vehicle-mounted signal equipment malfunctions, but the emergency communication module communicates normally with the control center, then the remote emergency mode will be entered.

[0117] If the control center issues commands to the existing vehicle-mounted signaling equipment normally, and the existing vehicle-mounted signaling equipment has not malfunctioned, then the disaster monitoring mode is entered.

[0119]

[0120] Based on the above embodiments, the system in this embodiment further includes:

[0121] The control converter is connected to the emergency control module and the train controller respectively. It is used to send control commands to the train controller if the existing on-board signaling equipment fails or if control authorization is provided, so that the train controller can control the current train to perform emergency operations. The control commands are determined based on the train status.

[0122] Specifically, when the onboard signaling equipment fails or control authorization is granted, the emergency control layer outputs control commands according to the emergency strategy. The control converter ensures that the system only outputs control commands to the train controller when the onboard signaling equipment fails or control authorization is granted, so that the train controller can control the current train to perform emergency operations.

[0123] This system serves as a backup system, with functions focused on executing emergency plans during disasters to prevent operational trains and passengers from being unable to evacuate to safe areas due to single-point failures in the signaling system.

[0124] In the event of a complete failure of the existing signal system, this system will utilize technologies such as image recognition and obstacle detection to perform safety actions as much as possible to ensure passenger safety.

[0125] In normal operation, when all systems are functioning properly, all emergency systems running on the line and the control center form a real-time disaster monitoring network to improve the ability to monitor disasters.

[0126] Figure 4 An example is a schematic diagram of the physical structure of an electronic device, such as... Figure 4 As shown, the electronic device may include: a processor 410, a communication interface 420, a memory 430, and a communication bus 440, wherein the processor 410, the communication interface 420, and the memory 430 communicate with each other via the communication bus 440. The processor 410 can call logical instructions in the memory 430 to execute a rail transit disaster recovery emergency control method, which includes:

[0127] Obtain current train environmental information, including fault information of onboard signaling equipment and disaster alarm information;

[0128] Based on the environmental information, the fault information, and the disaster alarm information, the current train status is determined;

[0129] If the control center issues an abnormal instruction to the existing onboard signaling equipment, or if the existing onboard signaling equipment malfunctions, the control center will perform emergency operations on the current train based on the train status.

[0130] Furthermore, the logical instructions in the aforementioned memory 430 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium. Based on this understanding, the technical solution of the present invention, essentially, or the part that contributes to the prior art, or a part of the technical solution, can be embodied in the form of a software product.
