Description

Technical Field

[0001] The present disclosure relates to the field of rail transit control technology, and in particular to a method, device, electronic equipment and train for switching train control modes. Background Art

[0002] At present, intercity railways mainly use CTCS train control systems, and urban rail lines mainly use CBTC train control systems. The intercity railway CTCS train control system and the urban rail line CBTC train control system are not unified in terms of interface, format, function, etc., and cannot be directly adapted to the train network control system, and cannot be compatible to achieve train control. The relevant technologies mainly use protocol adaptation (for example, converting the control commands of the intercity railway CTCS with the instruction format of the urban rail line CBTC) and interface standardization (for example, using a standard data format based on XML or JSON so that the two systems can share and understand each other's data) and other technologies to achieve coordinated coexistence between different train control systems.

[0003] The inventors have discovered that the related art has the following defects for trains adapted to multiple train control systems: different train control systems have their own communication protocols, data structures and control logics. When performing protocol adaptation, it is necessary to develop additional gateways or conversion layers to achieve communication between different systems, which increases the complexity of system design and implementation, and may bring risks such as communication delays or data loss; protocol adaptation and interface conversion require the introduction of additional processing steps, which may cause the system to experience a performance degradation in response speed and data transmission efficiency, making it difficult to meet actual needs.

[0027] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present disclosure. In the following detailed description, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

[0028] The terms used herein are only for describing specific embodiments and are not intended to limit the present disclosure. The terms "comprise", "include", etc. used herein indicate the existence of the features, steps, operations and / or components, but do not exclude the existence or addition of one or more other features, steps, operations or components.

[0029] All terms (including technical and scientific terms) used herein have the meanings commonly understood by those skilled in the art unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0030] When using expressions such as "at least one of A, B, and C, etc.", they should generally be interpreted according to the meaning of the expression commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include but is not limited to a system having A alone, B alone, C alone, A and B, A and C, B and C, and / or A, B, C, etc.).

[0031] In the technical solution of the present disclosure, the user information (including but not limited to user personal information, user image information, user device information, such as location information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved are all information and data authorized by the user or fully authorized by all parties, and the collection, storage, use, processing, transmission, provision, disclosure and application of the relevant data comply with relevant laws, regulations and standards, take necessary confidentiality measures, do not violate public order and good morals, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0032] In the process of conceiving the present disclosure, the inventors discovered that in the related art, for trains adapted to multiple train control systems, different train control systems have their own communication protocols, data structures and control logic. When performing protocol adaptation, it is necessary to develop additional gateways or conversion layers to achieve communication between different systems, which increases the complexity of system design and implementation, and may bring risks such as communication delays or data loss. Protocol adaptation and interface conversion require the introduction of additional processing steps, which may cause the system to experience a performance degradation in response speed and data transmission efficiency, making it difficult to meet actual needs.

[0033] In view of this, the present invention can achieve seamless and dynamic switching of trains between different train control mode models by acquiring train control right information, driving status information and mapping relationships. Since different train control modes are switched or maintained based on the mapping relationship between different modes and conditional information, different train control systems can be adaptively adjusted in different operating scenarios and complex conditions, avoiding the communication delay and data loss risks existing in traditional technologies through protocol adaptation or interface standardization. The implementation method is simple, ensuring the flexible adaptation of the system under different conditions, and further ensuring the accuracy and effectiveness of the train control function.

[0034] Embodiments of the present disclosure provide a method, apparatus, device, storage medium, program product and train for switching a train control mode. The method includes obtaining status information of the train, wherein the status information includes vehicle control right information and driving status information; and switching or maintaining the vehicle control mode of the train based on the vehicle control right information, driving status information and a mapping relationship, wherein the vehicle control mode includes an intercity mode, an urban rail mode and a manual mode, and the mapping relationship represents the correspondence between the intercity mode, the urban rail mode and the manual mode and a plurality of conditional information.

[0035] Figure 1 The application scenario diagram of the train control mode switching method, device, equipment, storage medium, program product and train according to the embodiment of the present disclosure is schematically shown.

[0036] like Figure 1 As shown, the application scenario according to this embodiment may include a first terminal device 101, a second terminal device 102, a third terminal device 103, a network 104, a server 105, and a detection device 106. The network 104 is used to provide a medium for a communication link between the first terminal device 101, the second terminal device 102, the third terminal device 103, and the server 105. The network 104 may include various connection types, such as wired, wireless communication links, or optical fiber cables, etc.

[0037] The detection device 106 can be used to detect the area where the train is located at a certain moment. For example, at time A, the detection device 106 detects that the train is in the intermediate conversion area between the intercity operation area and the urban rail operation area, then the conversion of the vehicle control mode can be triggered at this time. It is understandable that the detection device 106 can be a part of the train control device. The specific type of the detection device 106 can be set according to actual needs, such as detecting the position of the train through the conduction of current in the track circuit, or using the enhanced global navigation satellite system (EGNSS) combined with the global navigation satellite system (GNSS) and ground enhancement technology to determine the position information, or it can be a train on-board sensor (such as an inertial navigation system INS), or through a wireless communication system, the train and the ground control center exchange information in real time. The train can transmit position information through the communication equipment and receive control signals at the same time, and there is no specific limitation here.

[0038] The user may use at least one of the first terminal device 101, the second terminal device 102, and the third terminal device 103 to interact with the server 105 through the network 104 to receive or send messages, etc. Various communication client applications may be installed on the first terminal device 101, the second terminal device 102, and the third terminal device 103, such as shopping applications, web browser applications, search applications, instant messaging tools, email clients, social platform software, etc. (only for example).

[0039] The first terminal device 101, the second terminal device 102, and the third terminal device 103 may be various electronic devices having display screens and supporting web browsing, including but not limited to smart phones, tablet computers, laptop computers, desktop computers, and the like.

[0040] The server 105 may be a server that provides various services, such as a background management server (only as an example) that provides support for websites browsed by users using the first terminal device 101, the second terminal device 102, and the third terminal device 103. The background management server may analyze and process the received data such as user requests, and feed back the processing results (such as web pages, information, or data obtained or generated according to user requests) to the terminal device.

[0041] It should be noted that the method for switching the train control mode provided in the embodiment of the present disclosure can generally be executed by the server 105. Accordingly, the device for switching the train control mode provided in the embodiment of the present disclosure can generally be arranged in the server 105. The method for switching the train control mode provided in the embodiment of the present disclosure can also be executed by a server or a server cluster that is different from the server 105 and can communicate with the first terminal device 101, the second terminal device 102, the third terminal device 103 and / or the server 105. Accordingly, the device for switching the train control mode provided in the embodiment of the present disclosure can also be arranged in a server or a server cluster that is different from the server 105 and can communicate with the first terminal device 101, the second terminal device 102, the third terminal device 103 and / or the server 105.

[0042] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to implementation requirements.

[0043] The following will be based on Figure 1 The scene described by Figure 2~Figure 5 The method for switching the train control mode of the disclosed embodiment is described in detail.

[0044] Figure 2 A flow chart of a method for switching a train control mode according to an embodiment of the present disclosure is schematically shown.

[0045] like Figure 2 As shown, the method for switching the train control mode of this embodiment includes operations S210 to S220.

[0046] In operation S210, status information of the train is acquired, wherein the status information includes vehicle control right information and driving status information.

[0047] In an embodiment of the present disclosure, the status information may include vehicle control right information, driving status information, and train location information. The vehicle control right information may indicate whether the train corresponds to multiple vehicle control modes at the current moment and whether they are in a valid state. The vehicle control modes may include intercity mode, urban rail mode, and manual mode. The driving status information may indicate whether the current train is in automatic driving mode or manual driving mode. The train location information may be obtained in real time through detection equipment.

[0048] In operation S220, based on the vehicle control right information, the driving status information and the mapping relationship, the vehicle control mode of the train is switched or maintained, wherein the vehicle control mode includes intercity mode, urban rail mode and manual mode, and the mapping relationship represents the correspondence between the intercity mode, urban rail mode and manual mode and multiple condition information.

[0049] In an embodiment of the present disclosure, condition information may represent multiple state judgment conditions of the train, including: switch information, controller information and fault information. Controller information may include driver's cab control information and driver controller information. Fault information may represent information that the intercity mode or the urban rail mode is invalid under abnormal or faulty conditions. The correspondence between the intercity mode, the urban rail mode and the manual mode and multiple condition information may include a manual mode mapping relationship, an intercity mode mapping relationship and an urban rail mode mapping relationship. It can be understood that the location information of the train may include an intercity operating area and an urban rail operating area. When the train is in an intermediate transition area between the intercity operating area and the urban rail operating area, the vehicle control mode may be switched to meet the mode control requirements.

[0050] In a feasible embodiment, it is possible to first determine whether the train at the target time is in manual mode based on the direction switch information, controller information and fault information; when it is determined that the current mode is non-manual, the target train control mode of the train at the target time can be determined to be intercity mode or urban rail mode through the train control right information, controller information, driving status information and train position information; and then, when it is detected that the current train control mode does not meet the target train control mode, the current train control mode is switched, and when the current train control mode meets the target train control mode, the current train control mode is maintained.

[0051] In a feasible embodiment, the mapping relationship can also characterize the relationship between different operating modes (intercity mode, urban rail mode, manual mode) and vehicle control rights, driving status, train position, track type, etc. For example, a mapping table can be generated based on vehicle control rights information and driving status information. When it is detected that the train speed is greater than a certain threshold and the track type is an intercity track, it switches to the intercity mode; but if it is detected that the train is running on an urban track and the speed is low, it can be maintained or switched to the urban rail mode; when it is detected that the driver takes over the control, it switches to the manual mode.

[0052] For example, real-time data can be collected through sensors, global positioning systems, automatic train control systems (ATC), vehicle information acquisition systems, etc., and the collected real-time information can be transmitted to the train control system for processing; the train control system uses algorithms to make real-time analysis and decisions based on the collected vehicle control information and driving status information combined with preset mapping rules. For example, rule engines, fuzzy logic control, and machine learning algorithms can be used to optimize decisions; when the decision-making system determines the need to switch modes, the train control system can issue instructions to the train's control system (such as the CSTC2 ATO control system) through the communication network to perform mode switching operations.

[0053] According to the embodiments of the present disclosure, by acquiring the vehicle control right information, driving status information and mapping relationship, it is possible to achieve seamless and dynamic switching of trains between different vehicle control mode models. Since different vehicle control modes are switched or maintained based on the mapping relationship between different modes and condition information, it can meet the needs of different train control systems for adaptive adjustment in different operating scenarios and complex conditions, avoiding the communication delay and data loss risks existing in traditional technologies through protocol adaptation or interface standardization. The implementation method is simple, ensuring the flexible adaptation of the system under different conditions, and further ensuring the accuracy and effectiveness of the vehicle control function.

[0054] It can be understood that how to switch or maintain the train control mode has been described above, and how to determine the mapping relationship will be described below.

[0055] According to an embodiment of the present disclosure, multiple condition information includes switch information, controller information and fault information, and the controller information includes first controller information; the mapping relationship is determined by the following operations: determining the initial vehicle control mode based on the switch information, the first controller information and the fault information; and when the initial control mode is a non-manual mode and the condition information is met, switching the train to intercity mode or urban rail mode.

[0056] In an embodiment of the present disclosure, the switch information may represent the direction switch status information of the train. When the direction switch is not in the forward position, it indicates that the train control system is in the reverse mode or the direction setting is wrong, so a manual mode is required to ensure the correct operation of the train. The first controller information may represent the status information of the driver controller. When the driver controller is not in the "zero position", it indicates that the driver controller is in an operating state, the train is in a "manual intervention" state or an abnormality occurs during the operation, and a manual mode is also required to ensure the correct operation of the train. The initial vehicle control mode may include a manual mode and a non-manual mode.

[0057] For example, when the direction switch is not in the forward position, the driver controller is not in the zero position, and the intercity mode and the urban rail mode are both in a fault isolation state (invalid state), it is determined that the current mode is the manual mode.

[0058] For example, when the initial mode is non-manual mode, the train control mode in the future target time period can be determined as intercity mode or urban rail mode based on the train control right information, driving status information, controller information, location information and mapping relationship, and the current train control mode can be switched or maintained.

[0059] According to the embodiments of the present disclosure, by switching to intercity mode or urban rail mode through intelligent scheduling, track resources can be better utilized, empty running can be reduced, and the punctuality rate and transportation efficiency of trains can be improved. At the same time, in the non-manual control mode, the automatic control system can adjust the train operation parameters according to real-time data to reduce operation energy consumption and operation and maintenance costs.

[0060] It can be understood that an example of how to determine the mapping relationship has been described above, and an example of how to determine the inter-city mode will be described below.

[0061] According to an embodiment of the present disclosure, the controller information also includes second controller information, and the vehicle control right information includes intercity vehicle control right information; when the initial control mode is a non-manual mode and the conditional information is met, the train is switched to intercity mode or urban rail mode, including: when the initial control mode is a non-manual mode, and the second controller information, intercity vehicle control right information and driving status information meet their respective corresponding preset conditional information, the train is switched to intercity mode.

[0062] In the embodiments of the present disclosure, taking the intercity railway adopting the CTCS2 train control system and the urban rail adopting the CBTC train control system as an example, the vehicle control right information may include CTCS2 vehicle control right valid and CBTC vehicle control right valid; the driving state information may include CTCS2 ATO state and CBTC ATO state. The second controller information may represent the key-on state of the driver's cab.

[0063] For example, when the initial control mode is non-manual mode, CTCS2 control authority is valid, the driver's cab key is in the open state (the driver's cab of this train is occupied), CTCS2 ATO is in the valid state and CBTC control authority is invalid, the control mode of the current train can be determined as intercity mode.

[0064] It can be understood that an example of how to determine the intercity mode has been described above, and an example of how to determine the urban rail mode will be described below.

[0065] According to an embodiment of the present disclosure, the vehicle control right information also includes urban rail vehicle control right information; when the initial control mode is a non-manual mode and the conditional information is met, the train is switched to intercity mode or urban rail mode, including: when the initial control mode is a non-manual mode, and the second controller information, the urban rail vehicle control right information and the driving status information meet their respective corresponding preset conditional information, the train is switched to the urban rail mode.

[0066] In an embodiment of the present disclosure, when the initial control mode is non-manual mode, CBTC control authority is valid, the driver's cab key is in the open state (the driver's cab of this vehicle is occupied), CBTC ATO is in the valid state and CTCS2 control authority is invalid, the control mode of the current train can be determined as the urban rail mode.

[0067] Figure 3 An example diagram of a method for determining a train control mode according to an embodiment of the present disclosure is schematically shown.

[0068] like Figure 3 As shown, the method for determining the train control mode may include operations S301 to S308.

[0069] In operation S301, when the driver's cab of the vehicle is occupied, it can be detected whether CTCS2 and CBTC are both in the fault isolation state. When CTCS2 and CBTC are both in the fault isolation state, it is determined to be in manual mode.

[0070] In operation S302, when CTCS2 and CBTC are not all in fault isolation state, it is detected whether the direction switch is in the forward position or the driver controller is in the zero position. When the direction switch is not in the forward position or the driver controller is not in the zero position, it is determined to be in manual mode.

[0071] In operation S303, when the direction switch is in the forward position and the driver controller is in the zero position, it is detected whether the CTCS2 vehicle control right is valid, and it is initially detected whether the CBTC vehicle control right is valid.

[0072] In operation S304, when it is detected that the CTCS2 vehicle control right is valid, it is detected whether the CTCS2 ATO is valid.

[0073] In operation S305 , when it is detected that the CTCS2 vehicle control right is valid, the CBTC vehicle control right is invalid, and the CTCS2 ATO is valid, it is determined to be CTCS2 (intercity mode).

[0074] In operation S306, when it is detected that the CTCS2 vehicle control right is invalid, it is further determined whether the CBTC vehicle control right is valid.

[0075] In operation S307, when it is detected that the CBTC vehicle control right is valid, it is detected whether the CTCS2 vehicle control right is invalid.

[0076] In operation S308 , when it is detected that the CBTC vehicle control right is valid, the CTCS2 vehicle control right is invalid, and the CBTC ATO state is valid, the CBTC mode (urban rail mode) is determined.

[0077] It can be understood that an example of how to determine the urban rail mode has been described above, and how to control a train will be described below.

[0078] According to an embodiment of the present disclosure, the method further includes: when the train control mode is switched to the target mode, controlling the train based on the target mode and a target instruction corresponding to the target mode.

[0079] In an embodiment of the present disclosure, the target instruction may represent a control instruction corresponding to a target mode at a target moment. The target instruction may be determined according to the vehicle control mode at the target moment, including but not limited to a traction instruction, a braking instruction, a speed limit instruction, a steering control instruction, a door control instruction, and an automatic parking instruction.

[0080] Figure 4 An example diagram of a train control instruction output method according to an embodiment of the present disclosure is schematically shown.

[0081] like Figure 4 As shown, the method for determining the train control mode may include operations S401 to S404. In the state where the driver's cab of the train is occupied, it is detected whether the current train control mode is a manual mode.

[0082] In operation S401 , when it is detected that the train control mode of the current train is a manual mode, a manual train control instruction 410 may be transmitted to a plurality of controllers (eg, a traction controller, a brake controller) through a network control system.

[0083] In operation S402 , when it is detected that the current train control mode is a non-manual mode and it is detected that the current mode is a CTCS2 mode (intercity mode), a CTCS2 train control instruction 420 may be transmitted to a plurality of controllers through a network control system.

[0084] In operation S403, when it is detected that the train control mode of the current train is not the CTCS2 mode and when it is detected that the train control mode of the current train is the CBTC mode, the CBTC train control instruction 430 may be transmitted to a plurality of controllers through the network control system.

[0085] In operation S404, when it is detected that the current train control mode is not the manual mode, the urban rail mode and the intercity mode, a cyclic detection of the train control mode may be performed until the output of the control instruction is satisfied to control the train.

[0086] It can be understood that an example of how to control a train has been described above, and an example of how to perform braking processing will be described below.

[0087] According to an embodiment of the present disclosure, the method further includes: when the intercity mode and the urban rail mode are in the target state and the time length corresponding to the target state is greater than a preset time length threshold, braking the train.

[0088] In an embodiment of the present disclosure, the target state may include a mode valid state and a mode invalid state. The preset duration threshold may represent the duration threshold for detecting a certain train mode. For example, during the switching of the vehicle control mode, if the intercity mode and the urban rail mode are detected to be valid or invalid at the same time, and the duration of the state exceeds the preset duration threshold (for example, 2 seconds), it is determined as abnormal information to issue an alarm and take emergency braking.

[0089] In a feasible embodiment, during the switching process between different train control modes, a switching time threshold can be set. When it is detected that the switching time between two different modes exceeds the switching time threshold, it is determined as abnormal information and emergency braking is performed, and the train control command of the manual mode is adopted. For example, the train control system adopts the valid signal of the current device, and a 1-second switching delay can be set during the switching process of the train control mode to avoid the situation where both train control systems are not working or both are working during the switching process. During the switching process, the current system is kept in a valid state until the switching is completed.

[0090] Figure 5 An example diagram of an abnormal operating condition processing process according to an embodiment of the present disclosure is schematically shown.

[0091] like Figure 5 As shown, the abnormal operating condition processing method may include operations S501 to S506.

[0092] In operation S501, when the driver's cab of the vehicle is occupied, when it is detected that the switch direction is in the forward position and the driver controller is in the zero position, the vehicle control right information and fault information can be detected.

[0093] In operation S502, when it is detected that the CTCS2 vehicle control right is valid, it is further detected whether the CBTC vehicle control right is valid.

[0094] In operation S503, when it is detected that the CBTC vehicle control right is valid, it is further detected whether the duration of this state exceeds the duration threshold;

[0095] In operation S504, when it is detected that the CTCS2 vehicle control right is invalid and the CBTC vehicle control right is invalid, it is further detected whether the CTCS2 and CBTC vehicle control modes are fault-isolated.

[0096] In operation S505, when it is detected that the CTCS2 and CBTC vehicle control modes are not all fault isolation, it is further detected whether the duration of this state exceeds a duration threshold.

[0097] In operation S506, when it is detected that any one of the above time periods exceeds a preset time threshold, it is determined that the train is currently in an abnormal operating condition and emergency braking is performed through the network control system.

[0098] According to the embodiments of the present disclosure, by setting a preset duration threshold and a switching duration threshold, especially in a rail transit environment with high-frequency words and high safety requirements, a smooth transition during switching of the train control system can be ensured, avoiding dual control conflicts, loss of control, system misoperation and potential safety hazards, thereby improving the stability, safety and reliability of the entire system.

[0099] It can be understood that an example of how to perform braking processing has been described above, and an example of how to determine the manual mode will be described below.

[0100] According to an embodiment of the present disclosure, the target state includes a valid state; the method further includes: when the intercity mode, the urban rail mode, the manual mode and the corresponding instructions are in a valid state, determining the manual mode as the vehicle control mode.

[0101] In an embodiment of the present disclosure, when the monitoring equipment of the train detects that the control instructions corresponding to at least two modes of the intercity mode, the urban rail mode, and the manual mode are valid, it confirms the fault mode and issues an alarm, and at the same time sends a fault signal to the intercity train control system and the urban rail train control system.

[0102] For example, the CTCS2 train control system and the CBTC train control system may send conflicting instructions due to different dispatching strategies, or the instructions manually issued by the human operator may conflict with the instructions of the automatic control system, resulting in the train being unable to clearly execute which instruction. In this case, the system needs to be able to detect these conflicts in a timely manner to prevent the train from running uncontrolled or incorrectly.

[0103] For example, a fault signal can be sent to the CTCS2 train control system and the CBTC train control system. After receiving the fault signal, the CTCS2 train control system and the CBTC train control system can enter the fault detection mode and prevent safety accidents caused by command conflicts through self-inspection, shutdown or switching to safety mode.

[0104] According to the embodiments of the present disclosure, by detecting in real time the conflicts or inconsistencies in commands from multiple train control systems, faults can be quickly identified and alarms can be issued. Through the fault detection mechanism, safety hazards or uncontrolled trains caused by conflicting commands can be effectively prevented, ensuring the high reliability and safety of the system. The monitoring equipment can identify and process conflicting commands from multiple control systems, has a certain fault tolerance capability, can take corresponding error correction measures when an abnormality occurs, and can ensure that the train is in a safe and controlled state.

[0105] It can be understood that an example of how to determine the manual mode has been described above, and how to control a train under an abnormal network state will be further described below.

[0106] According to an embodiment of the present disclosure, the method further includes: when the network status of the train is an abnormal state, using the target device to transmit a control instruction to control the train.

[0107] In an embodiment of the present disclosure, the target device may include a relay and a hard-wired device. In an abnormal state, the method of controlling the train by transmitting control instructions using the target device may include train control system design, control mechanism of the target device and transmission of train control instructions.

[0108] In the embodiments of the present disclosure, in order to ensure that the train can still be safely and effectively controlled when the network control system fails, the train control system may include redundant control channels, automatic fault detection and switching mechanisms. Among them, the redundant control system may include a network control system (such as a CBTC system, a CTCS2 control system), and also a manual control mode (implemented by relays and hardware circuits). Ensure that when the network control system fails, it can quickly switch to the manual control mode to ensure that the train can continue to operate safely. When a network control system fails, it can automatically detect and switch to the manual control mode. By establishing a fault monitoring and alarm mechanism, the fault signal can be captured and the manual switch can be triggered.

[0109] For example, when manually switching the control mode, the train control system can transmit control instructions through hard wires and relays. The implementation methods may include: the control signal can be switched through relays, and the relays can act as a switch in the electrical circuit to switch the control instructions from the network control system to the manual control system; in manual mode, the relay connects the train control system with the manual control device (such as a manual control console, buttons, etc.), and is connected between the control system and the actuator (such as traction, braking system, etc.) through a hard wire to transmit traction, braking and other control instructions.

[0110] In an embodiment of the present disclosure, the manual mode can be set as the highest priority. For example, when it is determined that the direction switch is not in the forward position or the driver controller is not in the zero position, the vehicle will adopt the manual vehicle control mode command; when both train control systems are isolated from the fault, the manual vehicle control mode command is adopted.

[0111] Based on the above train control mode switching method, the present disclosure also provides a train control mode switching device. Figure 6 The device is described in detail.

[0112] Figure 6 The structural block diagram of the train control mode switching device according to an embodiment of the present disclosure is schematically shown.

In one embodiment, the mode switching module 620 can be used to perform the operation S220 described above, which will not be described in detail here.

[0116] According to the embodiments of the present disclosure, through the status information acquisition module 610 and the mode switching module 620 in the train control mode switching device, by acquiring the vehicle control right information, driving status information and mapping relationship, the train can be seamlessly and dynamically switched between different vehicle control mode models. Since different vehicle control modes are switched or maintained based on the mapping relationship between different modes and conditional information, different train control systems can be adaptively adjusted in different operating scenarios and complex conditions, avoiding the communication delay and data loss risks existing in traditional technologies through protocol adaptation or interface standardization. The implementation method is simple, ensuring the flexible adaptation of the system under different conditions, and further ensuring the accuracy and effectiveness of the vehicle control function.
