Description

Technical Field

[0001] This invention belongs to the field of subway vehicle technology, and in particular relates to a method and system for emergency alarm linkage control of subway vehicles and their passengers. Background Technology

[0002] As a crucial component of urban public transportation, the operational safety of rubber-tired subway trains directly impacts the safety of passengers' lives and property. During train operation, various emergencies may occur inside the passenger compartment, such as sudden illness, violent conflicts, or fires. In such cases, passengers need to use the emergency devices inside the train to alert the driver, and emergency stops and door openings for evacuation may be necessary at non-standard stations. Currently, emergency response to such incidents primarily relies on passengers manually triggering alarms and door unlocking devices, with the driver assessing the situation and executing appropriate actions. An efficient and interconnected automated emergency response mechanism has not yet been established.

[0003] Currently, the commonly used emergency control methods are:

[0004] (1) Emergency alarm and emergency stop control. Passengers can send an alarm signal to the driver's cab by pressing the alarm button on the emergency intercom alarm. After the driver connects to the intercom, both parties can communicate by voice. The driver needs to combine the video surveillance footage in the passenger compartment and the intercom content to determine whether to stop the vehicle immediately.

[0005] (2) Emergency door opening control. Passengers need to operate the emergency door unlocking device to request the driver to open the door. The driver then needs to report to the operation dispatch center and execute the stopping and door opening operations according to the instructions. Afterwards, the driver needs to manually reset the relevant device to restore normal operation. Although this method achieves emergency response to a certain extent, it has problems such as a long response chain, significant influence of human judgment factors, many operational steps, and slow response speed. In truly critical situations, it may delay the best time for handling the situation.

[0006] To improve the automation level of emergency response, existing technologies have undergone some improvements. For example, Chinese patent document CN113353042A discloses a passenger emergency braking and alarm linkage control system. When a passenger triggers the emergency braking device, the system can automatically activate the passenger emergency alarm, automatically apply the vehicle's emergency braking, and send the monitoring image of the corresponding location to the ground operation control center, which then sends control commands to the vehicle based on the image. However, this solution does not include the emergency door unlocking function in emergency situations within the linkage control scope. In scenarios where immediate door opening for evacuation is required, additional manual operation is still needed, failing to achieve full-process emergency linkage.

[0007] The Chinese patent document with the publication number CN111931563 discloses an emergency alarm supervision method for passenger vehicles. By monitoring the in-vehicle audio information, it automatically sends a distress signal in an emergency and transmits the in-vehicle audio and video information to the public security or traffic police system to assist in emergency response work. This solution focuses on information reporting and remote assistance, but does not establish a linkage mechanism among passenger emergency alarm, immediate vehicle stop, and emergency door opening in the passenger compartment, and cannot achieve integrated control of rapid braking and emergency door opening of the train.

[0008] In addition, the Chinese patent document with the publication number CN109808625 proposes an emergency alarm system for bus vehicles. After triggering the alarm switch, this system can connect the police terminal and the bus terminal, collect in-vehicle voice and images and transmit them to the police terminal, and can also control the opening and closing of the spraying device by the police terminal. This solution also does not involve the linkage function of emergency braking and emergency unlocking of the vehicle door, and cannot meet the coordinated control requirements of rapid stopping and door opening for evacuation of rubber-tired subway vehicles in an emergency.

[0009] In summary, in the prior art, for the handling of emergency situations in the passenger compartments of rubber-tired subway vehicles, there are still problems such as the independence of links such as alarm, stop, and door opening, reliance on manual judgment and operation, and insufficient response efficiency. There is an urgent need for a control system and method that can intelligently link functions such as passenger emergency alarm, vehicle emergency braking, and emergency door opening in the passenger compartment to achieve fast, automatic, and coordinated emergency response and improve the safety and reliability of vehicle operation. Summary of the Invention

[0010] Aiming at the above-mentioned defects in the prior art, the purpose of the present invention is to provide a subway vehicle and its passenger emergency alarm linkage control method and system to solve the technical problems of inefficient handling and slow response caused by the fragmentation of emergency response links and reliance on manual judgment and operation in the prior art, and the inability to achieve integrated automatic linkage of alarm, stop, and door opening for evacuation in an emergency.

[0011] The present invention solves the above technical problems through the following technical solutions: A passenger emergency alarm linkage control method for a subway vehicle, including:

[0012] In response to an emergency alarm signal triggered by a passenger, execute system-level linkage control; wherein, the linkage control includes:

[0013] Start an alarm reminder and report the alarm trigger location information to the driver's cab and / or the remote monitoring center;

[0014] Automatically decide whether to immediately apply emergency braking based on the real-time running speed of the vehicle; among which, when the real-time running speed of the vehicle is less than the preset speed threshold, trigger emergency braking; when the real-time running speed of the vehicle is greater than or equal to the preset speed threshold, inhibit the triggering of emergency braking;

[0015] After the vehicle stops stably, automatically unlock the service side door of the carriage corresponding to the alarm trigger position; and control the opening of the door based on the safety status of the vehicle stop position.

[0016] The core of the present invention lies in defining a system-level linkage response. Once a passenger triggers an alarm, the system no longer simply notifies the driver, but automatically and concurrently starts a series of predetermined emergency procedures (alarm, reporting, speed decision-making, door preparation).

[0017] The present invention automatically decides whether to brake based on speed, and the system decides whether to immediately stop according to the preset and scientific safety logic, eliminating delays or incorrect decisions caused by insufficient information, nervous hesitation or misjudgment of the driver.

[0018] Automatically unlocking the door saves the driver's time to find and operate the unlocking device. Subsequently, controlling the door opening based on the safety status balances the evacuation speed and absolute safety, automatically opens the door at the platform, and waits for the driver's final confirmation in the section, taking into account both efficiency and safety.

[0019] Furthermore, while reporting the alarm trigger position information to the driver's cab and / or the remote monitoring center, also control the camera to focus on the alarm trigger position and send the monitoring video to the driver's cab and / or the remote monitoring center.

[0020] In this embodiment, when the driver's cab and the remote monitoring center receive the text / voice alarm, they can also immediately see the real-time video of the incident carriage, upgrading the driver's response from the passive state of hearing the alarm to the active state of seeing the scene, which is more conducive to ruling out false alarms or minor situations, preventing unnecessary emergency stops due to insufficient information and affecting the operation efficiency; at the same time, it saves the time consumption of the driver asking the passengers through the intercom system or the remote monitoring center (such as the dispatching center) contacting the driver to describe the situation, shortening the decision-making link and improving the reaction speed.

[0021] Furthermore, based on the safety status of the vehicle stop position, issue an opening instruction for the door, including:

[0022] If the vehicle stops in the platform area, automatically issue an opening instruction for the door;

[0023] If the vehicle stops in a non-platform area, wait for and respond to the driver's door opening confirmation instruction, and then issue an opening instruction for the door.

[0024] In this embodiment, in the platform area, the system automatically issues a door opening command, achieving seamless connection of the evacuation process and greatly improving the efficiency of emergency evacuation; in non-platform areas, the system does not automatically open the door, but waits for the driver's confirmation, avoiding catastrophic secondary accidents such as passengers falling into the track area or coming into contact with high-voltage equipment due to automatic door opening in dangerous areas such as tunnels.

[0025] Furthermore, the method also includes reset control, specifically including: in response to a reset command, releasing the linkage control state triggered by the emergency alarm.

[0026] In this embodiment, all linkage states triggered by the alarm (such as brake blockage, video focus, special door access, etc.) can be released by a reset command, without requiring the driver to go to multiple locations to manually reset.

[0027] Based on the same concept, this invention provides a subway vehicle passenger emergency alarm linkage control system for implementing the subway vehicle passenger emergency alarm linkage control method described above. The system includes:

[0028] An emergency alarm triggering device, located in the passenger compartment, is used to respond to passenger operations and generate an emergency alarm signal;

[0029] The main controller is configured to perform linkage control in response to the emergency alarm signal, the main controller comprising:

[0030] The system includes a status monitoring and reporting unit for initiating alarm notifications and reporting alarm trigger location information to the driver's cab and / or a remote monitoring center; a braking decision unit for automatically deciding whether to issue an emergency braking command based on the vehicle's real-time operating speed; wherein, when the vehicle's real-time operating speed is less than a preset speed threshold, emergency braking is triggered; when the vehicle's real-time operating speed is greater than or equal to the preset speed threshold, the triggering of emergency braking is suppressed; and an evacuation control unit for automatically issuing an unlocking command to the service side door of the passenger compartment corresponding to the alarm trigger location to the door system after the vehicle has come to a complete stop; and issuing a door opening command based on the safety status of the vehicle's stopped position.

[0031] A brake actuator for responding to an emergency braking command from the main controller;

[0032] A door actuator is used to respond to the unlocking and opening commands of the main controller;

[0033] The system includes a reset module, which is used to reset the emergency alarm triggering device in response to a reset command from the vehicle's local or remote location, and to release the linkage control state triggered by the alarm.

[0034] Furthermore, the emergency alarm triggering device is a passenger emergency alarm operating handle.

[0035] Furthermore, the main controller includes a vehicle control and management system and a vehicle signal system;

[0036] In manual driving mode, the vehicle control and management system serves as both the braking decision unit and the evacuation control unit; in CBTC vehicle control mode, the vehicle signal system serves as both the braking decision unit and the evacuation control unit.

[0037] Furthermore, the status monitoring and reporting unit is a passenger information system. While reporting the alarm trigger location information to the driver's cab and / or the remote monitoring center, the passenger information system also controls the camera to focus on the alarm trigger location and sends the monitoring image to the driver's cab and / or the remote monitoring center.

[0038] In this embodiment, the decision-making entity under different operating conditions is clearly defined through a mode adaptation mechanism, forming a natural logical redundancy. In manual driving mode, TCMS works independently, while in CBTC vehicle control mode, the two work collaboratively. This architecture ensures that the system has complete emergency response capabilities and no blind spots of responsibility under any normal operating mode.

[0039] By embedding optimal emergency response procedures into the system's built-in logic, it ensures that every emergency is executed according to a pre-set, scientifically unified plan. The response speed and operational accuracy remain consistent regardless of differences in driver experience, ability, or psychological state. Simultaneously, the automatic video linkage function provides drivers and remote monitoring centers (such as operations dispatch centers) with intuitive on-site views, enabling "visualized command and decision-making" and significantly improving the accuracy of remote support and management.

[0040] Furthermore, the system also includes a vehicle hardwired control circuit, which is connected to the emergency alarm triggering device, the brake actuator, and the door actuator.

[0041] The vehicle hardwired control circuit is used to monitor the alarm status of the emergency alarm triggering device in real time, and automatically decide whether to issue an emergency braking command based on the real-time running speed of the vehicle when the main controller fails; in response to the driver's operation, it issues a door opening command to the door actuator.

[0042] Furthermore, the main controller also includes a vehicle event recorder, used to monitor and record the alarm status of the emergency alarm triggering device and the vehicle's operating speed in real time.

[0043] Based on the same concept, the present invention also provides a subway vehicle, including the subway vehicle passenger emergency alarm linkage control system as described above.

[0044] Compared with existing technologies, the emergency alarm linkage control method and system for subway vehicles and their passengers provided by this invention achieves the following significant benefits by deeply integrating multiple previously independent aspects such as alarm, braking, and door control into an intelligent linkage response system:

[0045] This invention, through system-level coordinated control, compresses the lengthy, sequential process requiring passengers or drivers to perform actions step-by-step (e.g., alarm -> driver answers -> driver checks video -> driver assesses and brakes -> driver reports -> dispatcher issues order -> driver unlocks and opens door) into a simplified process of "one-button triggering by the passenger, with the system automatically executing in parallel." The total time from alarm to braking and door preparation is reduced to the second level, gaining valuable time for life-saving and emergency response within the carriage, and greatly improving efficiency.

[0046] This invention makes intelligent decisions on whether to apply emergency braking immediately based on real-time operating speed. When the speed is below a preset speed threshold, it is automatically triggered to ensure rapid stopping; when the speed is above or equal to the preset speed threshold, the triggering is suppressed, avoiding secondary accidents such as passenger falls and vehicle instability that may be caused by emergency braking in high-speed environments. This achieves a fundamental shift from "unconditional braking" to "intelligent safety braking".

[0047] After the vehicle comes to a complete stop, the system automatically unlocks the corresponding doors and intelligently controls their opening based on the safety status of the stopping position: in the platform area, the doors open automatically for rapid evacuation; in non-platform areas, the system waits for the driver's final confirmation, effectively preventing secondary safety accidents such as passengers falling onto the tracks.

[0048] This invention encompasses multiple control paths, including the Vehicle Control and Management System (TCMS), the Signaling System (CBTC), and hardwired control circuitry. This ensures that in the event of a TCMS failure, the backup system can still take over and perform core braking and evacuation functions, significantly improving system availability and fault survivability. Simultaneously, convenient local and remote reset mechanisms enable rapid restoration of normal operation after incident handling, minimizing the impact on the overall line operation.

[0055] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0056] The technical solution of the present invention will be described in detail below with reference to specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0057] Example 1

[0058] Figure 1 A schematic diagram of the passenger emergency alarm linkage control system for rubber-tired subway vehicles provided in an embodiment of the present invention is shown. The control system includes an emergency alarm triggering device (such as a passenger emergency alarm operating handle KFS), a vehicle control and management system (TCMS), a vehicle signaling system (CBTC), a passenger information system (PIDS), a vehicle braking system (including brake actuators), a door system (including door actuators), a remote monitoring center (such as an operations dispatch center (PCC)), a backup vehicle hardwired control circuit, and a vehicle event recorder.

[0059] Passenger emergency alarm control handles KFS1~KFSN: distributed in each passenger compartment, for passengers to trigger the alarm, and can be remotely reset.

[0060] Vehicle Control and Management System (TCMS): As the core of vehicle-level control, it is responsible for status monitoring, logical decision-making, and command execution.

[0061] CBTC (Centralized Bus Control System): As the core of line-level control, it has the highest decision-making authority in signal-controlled vehicle mode.

[0062] Passenger Information System (PIDS): Responsible for video linkage and information display.

[0063] Operations and Dispatch Center (PCC): Ground Remote Monitoring and Command Center.

[0064] Vehicle braking system: Executes braking commands.

[0065] Vehicle door system: executes door unlocking and opening commands.

[0066] Vehicle hardwired control circuit: A backup safety control circuit activated in the event of a TCMS failure.

[0067] Vehicle Event Recorder (EVR): Used to record alarm events and related data.

[0068] like Figure 2 As shown, the subway vehicle passenger emergency alarm linkage control method provided in this embodiment of the invention includes the following steps:

[0069] Step S1: Alarm Triggering and Status Reporting

[0070] In the event of an emergency in the passenger compartment, the passenger operates the passenger emergency alarm handle (KFS) next to them. Once the handle is triggered, an emergency alarm signal is generated.

[0071] like Figure 3 and Figure 4 As shown, the TCMS system monitors the operational status of every KFS (Keeper Window System) in the entire vehicle in real time and graphically displays its normal / alarm status on the HMI (Hardware Interface) screen in the driver's cab. Specifically, when a KFS is operated and triggers an emergency alarm, the TCMS system detects in real time that the KFS's status has changed to "triggered" and immediately generates an audible and visual alarm on the HMI screen in the driver's cab to alert the driver. At the same time, the TCMS system sends the precise location number of the triggered KFS (e.g., "Car 3, Door 2") to the Passenger Information System (PIDS).

[0072] like Figure 5 As shown, the CBTC system, like EVR, performs hardwired monitoring and recording of the KFS status, forming multiple redundancies to ensure the reliability of status detection. Simultaneously, the CBTC system also sends the KFS status and its precise location number to the Operations Dispatch Center (PCC), completing the reporting to the remote monitoring center.

[0073] After receiving the KFS location information, the Passenger Information System (PIDS) immediately controls the passenger compartment camera closest to the KFS to adjust its angle and focus on the alarm trigger area. The real-time monitoring image of the camera is then forcibly displayed on the CCTV screen in the driver's cab (i.e., the passenger information system's screen in the driver's cab). At the same time, the image stream is transmitted to the Operations Dispatch Center (PCC) via the vehicle-to-ground wireless network.

[0074] The TCMS system records the operational status of each KFS (Kinetic Field Storage) on the entire train, while the EVR and CBTC systems record whether a KFS is being operated via hard-wired signals.

[0075] In one specific embodiment of the present invention, when a passenger operates any KFS, the system enters two response states depending on whether the TCMS system is working properly:

[0076] The TCMS system is functioning normally: TCMS changes the corresponding KFS status on the HMI display and sends its location number to the Passenger Information System (PIDS) and the CBTC system. The PIDS immediately controls the nearest camera to focus on the alarm trigger area, forcibly displaying the image on the CCTV screen in the driver's cab and uploading it to the Operations Dispatch Center (PCC). The CBTC system transmits the location number information sent by TCMS to the PCC, activating the vehicle's hardwired control circuit to ring the alarm. This alarm triggering and status reporting process is completed within seconds, enabling the driver and the PCC to immediately know the location of the incident and the situation on site.

[0077] TCMS system failure: Under this redundant backup condition, the vehicle hardwired control circuit becomes the main control unit. The vehicle hardwired control circuit directly activates the ringing, and the CBTC system uploads the alarm information monitored by the vehicle hardwired control circuit to the Operations Dispatch Center (PCC).

[0078] Step S2: Speed-adaptive emergency braking decision and execution.

[0079] The system automatically makes different braking decisions based on the vehicle's real-time operating speed.

[0080] Scenario 1: The TCMS system is working normally and the vehicle's real-time operating speed is less than the preset speed threshold (e.g., 35 km / h).

[0081] In manual driving mode, the TCMS system acts as the decision-maker, immediately triggering an emergency braking command and controlling the brake actuators in the vehicle's braking system to perform a stopping action.

[0082] In CBTC vehicle control mode, the CBTC system acts as the decision-making entity, deciding to apply emergency braking and sending the decision to the vehicle's braking system via the TCMS system to control the brake actuators to perform the stopping action, bringing the vehicle to a stop as quickly as possible.

[0083] Scenario 2: The TCMS system malfunctions and the vehicle's real-time operating speed is lower than the preset speed threshold (e.g., 35 km / h).

[0084] The vehicle's hardwired control circuit triggers an emergency braking command, controlling the brake actuators in the vehicle's braking system to perform a stopping action.

[0085] Scenario 3: The TCMS system is working normally and the vehicle's real-time operating speed is greater than or equal to the preset speed threshold (e.g., 35 km / h).

[0086] In manual driving mode, the TCMS system acts as the decision-maker, suppressing the triggering of emergency braking, i.e., not immediately applying emergency braking; in CBTC vehicle control mode, the CBTC system acts as the decision-maker, suppressing the triggering of emergency braking, i.e. not immediately applying emergency braking.

[0087] Regardless of the mode, emergency braking is suppressed to prevent passenger injuries or vehicle accidents caused by emergency braking at high speeds. At this point, the system relies on the audible and visual alarms and video linkage established in step S1 to strongly alert the driver to intervene. After reviewing the CCTV footage and using the intercom to understand the situation, the driver makes a manual decision and applies smooth, conventional braking to drive the train to the next platform for further handling.

[0088] Scenario 4: The TCMS system malfunctions and the vehicle's real-time operating speed is greater than or equal to the preset speed threshold (e.g., 35 km / h).

[0089] The vehicle's hardwired control circuit does not trigger an emergency braking command. At this point, the system relies on the ringing alarm and reporting to the Operations Dispatch Center (PCC) established in step S1. Upon hearing the continuous ringing alarm, the driver immediately confirms with the PCC via the vehicle radio or dedicated telephone to learn that an emergency alarm has been triggered in the passenger compartment and to ascertain the specific location of the triggered car. The driver becomes the decision-maker; instead of applying emergency braking, the driver uses conventional braking to smoothly guide the vehicle to the next station. Alternatively, under explicit instructions from the PCC, the driver applies emergency braking to stop the vehicle within the designated section and awaits further instructions from the PCC.

[0090] When the vehicle's real-time operating speed is greater than or equal to a preset speed threshold, no matter how the passenger operates the KFS, the TCMS system, CBTC system, or the vehicle's hardwired control circuit will trigger an emergency braking command.

[0091] Step S3: Evacuation and Resettlement after Arrival and Stopping

[0092] In manual driving mode, when the vehicle's real-time operating speed is less than the preset speed threshold, the TCMS system triggers an emergency braking command, controls the vehicle's braking system to immediately apply emergency braking to stop the vehicle, sends the device number of the operated KFS to the door system, and controls all service-side doors of the corresponding car to automatically unlock. Whether the doors are opened is decided by the driver. After the driver issues the door opening command, all service-side doors of the car are opened.

[0093] In manual driving mode, when the vehicle's real-time operating speed is greater than or equal to the preset speed threshold, the TCMS system will not trigger an emergency braking command, and all doors will not unlock automatically. Even if the vehicle's real-time operating speed is less than the preset speed threshold and other KFSs are operated again, all doors will still not unlock automatically until the driver controls the vehicle to stop at the platform and the driver issues the door opening command, at which point all doors on the service side of the carriage will open.

[0094] In CBTC vehicle control mode, when the vehicle's real-time operating speed is 0, the CBTC system triggers an emergency braking command, controlling the vehicle's braking system to immediately apply emergency braking to stop the vehicle. After the vehicle comes to a complete stop at the platform, the CBTC system issues unlocking and opening commands to the service side doors of the carriage corresponding to the alarm trigger location, and all service side doors of the carriage are opened.

[0095] In CBTC vehicle control mode, when the vehicle's real-time operating speed is less than the preset speed threshold but greater than 0, the CBTC system triggers an emergency braking command, controlling the vehicle's braking system to immediately apply emergency braking to stop the vehicle. After the vehicle comes to a complete stop, the CBTC system sends the device number of the operated KFS to the door system through the TCMS system, controlling all service-side doors of the corresponding car to automatically unlock. Whether the doors are opened is decided by the CBTC system. After the CBTC system issues the door opening side and door opening command, all service-side doors of the car are opened.

[0096] In CBTC vehicle control mode, when the vehicle's real-time operating speed is greater than or equal to the preset speed threshold, the CBTC system will not trigger an emergency braking command, and all doors will not unlock automatically. Even if the vehicle's real-time operating speed is less than the preset speed threshold and other KFSs are operated again, all doors will still not unlock automatically until the driver controls the vehicle to stop at the platform and the CBTC system automatically issues a door opening request or the driver manually issues a door opening command on the CBTC system display screen, at which point all doors on the service side of the carriage will open.

[0097] In the event of a TCMS system malfunction, regardless of the vehicle's real-time operating speed, whether the doors are open is controlled by the driver. After the driver issues the door opening command, all doors on the service side of the vehicle will open.

[0098] When the vehicle is parked in the platform area: In manual driving mode, the driver presses the door opening button to issue the door opening command; in CBTC vehicle control mode, the CBTC automatically issues the door opening command.

[0099] When a vehicle is parked in a non-platform area: After the driver assesses the safety of the external environment through the CCTV display screen and confirms that the side with the door is the emergency evacuation platform, the door can be opened after the "door opening confirmation" operation is completed.

[0100] After the emergency has been resolved, the device can be reset in the following ways:

[0101] In manual driving mode, the driver can manually reset the KFS at the KFS installation location in the passenger compartment using an operating tool, or the driver can reset the KFS by operating the KFS reset soft button on the HMI display of the TCMS system, thus relieving the vehicle's emergency braking.

[0102] In CBTC vehicle control mode, the driver can manually reset the KFS at the KFS installation location in the passenger compartment using an operating tool, or the driver can reset the KFS by operating the KFS reset soft button on the HMI display of the TCMS system, or the operations management personnel can reset the KFS by operating the KFS reset soft button on the display of the PCC of the operations dispatch center, triggering the KFS reset command to the TCMS system to remotely reset the KFS and alleviate the vehicle's emergency braking.

[0103] The driver operates a single KFS reset soft button on the HMI display of the TCMS system to issue a command to the TCMS system. After receiving the "Operate XX (device number) KFS Reset" command, the TCMS system controls the corresponding camera through the Passenger Information System (PIDS) to defocus on the operated XX (device number) KFS area, and the TCMS system will no longer trigger emergency braking caused by the operated KFS.

[0104] In the event of a TCMS system malfunction, the driver can manually reset the KFS at its installation location in the passenger compartment using an operating tool, or reset the KFS by operating the emergency brake bypass switch (KAD) of the vehicle's hardwired control circuit, thereby relieving the vehicle's emergency braking.

[0105] After resetting, the system relieved the emergency braking, canceled the video focus, and restored normal door control, and the train was ready to be put back into operation.

[0106] This invention has been practically applied to a rubber-tired subway system, reducing the driver's operational steps and workload in emergency situations, and improving the vehicle's rapid response efficiency and safety in emergency situations. Specifically, the driver's operational steps have been reduced by approximately 60%, significantly alleviating their workload; the initial emergency response time after a passenger alarm has been shortened by more than 30%; and secondary accidents have been avoided through rapid-sensitive braking and safe door opening logic, improving vehicle safety indicators by more than 3%.

[0107] Example 2

[0108] An embodiment of the present invention further provides a subway vehicle passenger emergency alarm linkage control system for implementing the subway vehicle passenger emergency alarm linkage control method in the first embodiment. The linkage control system includes an emergency alarm trigger device, a main controller, a vehicle braking system, a door system, and a reset module; the main controller includes a status monitoring and reporting unit, a braking decision-making unit, and an evacuation control unit; the vehicle braking system includes a braking actuator; the door system includes a door actuator.

[0109] The emergency alarm trigger device is arranged in the passenger compartment and is used to respond to the operation of passengers and generate an emergency alarm signal.

[0110] The main controller is configured to execute linkage control in response to the emergency alarm signal generated by the emergency alarm trigger device. Specifically, the status monitoring and reporting unit is used to start an alarm reminder and report the alarm trigger position information to the driver's cab and / or the remote monitoring center; the braking decision-making unit is used to automatically decide whether to issue an emergency braking instruction according to the real-time running speed of the vehicle. Among them, when the real-time running speed of the vehicle is less than the preset speed threshold, an emergency braking is triggered; when the real-time running speed of the vehicle is greater than or equal to the preset speed threshold, the triggering of the emergency braking is inhibited; the evacuation control unit is used to automatically send an unlocking instruction for the car body service side door corresponding to the alarm trigger position to the door system after the vehicle stops; and issue an opening instruction for the door based on the safety status of the vehicle stop position.

[0111] The braking actuator is used to respond to the emergency braking instruction of the main controller; the door actuator is used to respond to the unlocking instruction and the opening instruction of the main controller; the reset module is used to respond to a reset instruction from the vehicle local or remote, reset the emergency alarm trigger device, and解除 the linkage control state triggered by the alarm.

[0112] In a specific embodiment of the present invention, as Figure 1 shown, the main controller includes a vehicle control and management system TCMS and a vehicle signal system CBTC.

[0113] In the manual driving mode, the vehicle control and management system TCMS serves as the braking decision-making unit and the evacuation control unit, that is, the TCMS system automatically decides whether to issue an emergency braking instruction according to the real-time running speed of the vehicle. After the vehicle stops, it automatically sends an unlocking instruction for the car body service side door corresponding to the alarm trigger position to the door system; and issue an opening instruction for the door based on the safety status of the vehicle stop position.

[0114] It should be noted that there is an error in the original Chinese text where "解除" is used. I assume it should be "解除" in Chinese, which means "release" or "解除" in English. The above translation has corrected this error. If this is not what you intended, please let me know.In CBTC vehicle control mode, the vehicle signal system CBTC serves as the braking decision unit and evacuation control unit. That is, the CBTC system automatically decides whether to issue an emergency braking command based on the vehicle's real-time operating speed. After the vehicle comes to a complete stop, it automatically sends an unlocking command to the service side door of the passenger compartment corresponding to the alarm trigger position to the door system; and issues a door opening command based on the safety status of the vehicle's stopped position.

[0115] In one specific embodiment of the present invention, the status monitoring and reporting unit is a passenger information system. Specifically, when a KFS is operated and triggers an emergency alarm, the TCMS system monitors the KFS's status in real time and immediately generates an audible and visual alarm on the HMI display in the driver's cab to alert the driver. At the same time, the TCMS system sends the precise location number of the triggered KFS (e.g., "Car 3, Door 2") to the passenger information system PIDS. After receiving the KFS location information, the passenger information system PIDS immediately controls the passenger compartment camera closest to the KFS to adjust its angle and focus on the alarm trigger area, and forcibly pops up and displays the real-time monitoring image of the camera on the CCTV display screen in the driver's cab (i.e., the passenger information system's display screen in the driver's cab), while simultaneously transmitting the image stream to the Operations Dispatch Center (PCC) via the vehicle-to-ground wireless network.

[0116] In one specific embodiment of the present invention, the system further includes a vehicle hardwired control circuit, which is connected to an emergency alarm triggering device, a brake actuator, and a door actuator. The vehicle hardwired control circuit monitors the alarm status of the emergency alarm triggering device in real time, and automatically decides whether to issue an emergency braking command based on the real-time running speed of the vehicle when the TCMS system fails. In response to the driver's operation, it issues a door opening command to the door actuator.

[0117] In one specific embodiment of the present invention, the main controller further includes a vehicle event recorder for real-time monitoring and recording of the alarm status of the emergency alarm triggering device and the vehicle's operating speed.

[0118] The above description only discloses specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or modifications that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
