Description

Technical Field

[0001] The invention relates to a train emergency evacuation method, and in particular to a train full-automatic emergency evacuation method, device, equipment and medium. Background Art

[0002] In urban rail transit operations, when a fire occurs in a train or the emergency evacuation handle is pulled down, passengers need to be evacuated urgently. Under emergency evacuation conditions, the train faces the problem of being unable to enter the safe evacuation area, and there is also the risk of being hit by subsequent trains on the same track or trains on adjacent tracks. Therefore, different emergency evacuation plans need to be adopted according to the different operating positions and operating states of the train to protect the safety of passengers.

[0003] After searching, Chinese Patent Publication No. 111776014A discloses a method for evacuating passengers from a train, which specifically discloses that when an emergency occurs while a train is traveling on a section and passengers need to be evacuated, an evacuation request is sent to the dispatch center, and the onboard controller drives to the target evacuation platform according to the evacuation command sent by the dispatch center. After the regional controller establishes the protection zone of the train, the emergency evacuation of passengers is carried out. However, the patent fails to consider the situation where the train itself fails or is unable to continue running due to other reasons. At the same time, the patent ignores the fact that when the train intersects with the platform, passengers can be organized to get off the station directly for rapid evacuation, or other application scenarios that can optimize the evacuation process. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a train full-automatic emergency evacuation method, device, equipment and medium.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0006] According to a first aspect of the present invention, a fully automatic emergency evacuation method for a train is provided, the emergency evacuation method comprising the following steps:

[0007] Step S1, the driver or passenger triggers an emergency evacuation activation signal;

[0008] Step S2, the vehicle controller collects the control signal;

[0009] Step S3, the vehicle controller sends different control instructions to switch the corresponding emergency evacuation mode according to the different control signals collected;

[0010] Step S4, the train or dispatching center executes the corresponding control instructions. After the execution is completed, the passengers are evacuated in an orderly manner according to the regulations;

[0011] Step S5: emergency evacuation mode is released.

[0012] As a preferred technical solution, the trigger switch of the emergency evacuation activation signal in step S1 is an emergency handle in the driver's cab or an emergency handle in the passenger compartment.

[0013] As a preferred technical solution, pressing any one of the cab emergency handle or the passenger compartment emergency handle will trigger an emergency evacuation activation signal.

[0014] As a preferred technical solution, the control signal of the train in step S2 includes the driving status and position of the train;

[0015] The driving status of the train includes normal operation and abnormal operation, the normal operation of the train includes normal parking and normal driving, and the abnormal operation of the train includes failure to start, failure to brake and automatic stop due to fault;

[0016] The position of the train includes within the section and outside the section.

[0017] As a preferred technical solution, the train being within the section means that no matter what driving status the train is in, as long as there is at least one complete carriage in the platform area, the train is determined to be within the section; otherwise, the train is determined to be outside the section.

[0018] As a preferred technical solution, the control instructions in step S3 include:

[0019] a) The train runs to the next stop platform;

[0020] b) Apply emergency brakes to the train;

[0021] c) The train automatically releases the door to open and remain open;

[0022] d) Send an emergency evacuation request signal to the dispatching center, which will control the regional controller to demarcate the evacuation protection area. At the same time, the dispatching center will send a spare train to the faulty train to transfer passengers to the evacuation protection area;

[0023] e) Start the timer and set the initial countdown value. During the countdown period, the automatic release door remains closed. When the countdown reaches 0, the automatic release door opens and remains open;

[0024] The emergency evacuation mode includes:

[0025] Mode 1: determine that the position of the train is within the interval, and when the driving status is normal parking or unable to start or fault self-stop, execute the control instruction c);

[0026] Mode 2: determining that the position of the train is within the interval, when the driving state is normal driving or unable to brake, immediately executing the control instruction b), and then executing the control instruction c);

[0027] Mode three, determining that the position of the train is outside the interval, and when the driving state is normal operation, executing the control instruction a);

[0028] Mode 4, when it is determined that the position of the train is outside the section, when the driving status is unable to brake and the train stops automatically due to a fault, the control instruction b) is immediately executed, and then the control instructions d) and e) are executed at the same time.

[0029] As a preferred technical solution, when demarcating the evacuation protection zone, the regional controller first drives the existing trains in the evacuation protection zone out of the evacuation protection zone. The evacuation protection zone does not allow other trains outside the evacuation protection zone to enter during the period when the emergency evacuation state is not released.

[0030] As a preferred technical solution, the initial countdown value set for the timer is the time taken by the dispatching center to prepare a spare train and drive to the faulty train.

[0031] As a preferred technical solution, when the timer is in the off state, the opening and closing of the train's automatic release door is controlled by the automatic release door switch button in the cab. After the timer is started, the train's automatic release door is controlled by the timer.

[0032] As a preferred technical solution, the emergency evacuation mode release in step S5 specifically includes:

[0033] Reset the emergency handles in the cab and the passenger compartment;

[0034] If an emergency evacuation request signal is sent to the dispatch center, the request signal will be revoked, the evacuation protection zone will be lifted, and the timer will be turned off.

[0035] According to a second aspect of the present invention, there is provided a device for the fully automatic emergency evacuation method of a train, the device comprising an onboard controller, a zone controller and a timer;

[0036] The on-board controller is installed on the train and is used to collect control signals, switch corresponding emergency evacuation modes according to different control signals, send control instructions to the train driving system or send emergency evacuation request signals to the dispatching center;

[0037] The area controller and the timer are controlled by the dispatch center server. When receiving the emergency evacuation request signal sent by the vehicle controller, the dispatch center server simultaneously controls the start-up of the area controller and the timer and executes the corresponding control instructions.

[0038] According to a third aspect of the present invention, there is provided an electronic device, comprising a memory and a processor, wherein a computer program is stored in the memory, and the method described above is implemented when the processor executes the program.

[0039] According to a fourth aspect of the present invention, there is provided a computer-readable storage medium having a computer program stored thereon, wherein the program implements the method described when executed by a processor.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] The present invention can automatically switch to the best emergency evacuation mode for dealing with different situations according to different train driving status and train positions, thereby improving the efficiency of train emergency evacuation and saving manpower and material resources; at the same time, the present invention optimizes the process of seeking help from the dispatching center, and only initiates an emergency evacuation request to the dispatching center when the train has a driving failure and is located outside the section, which can relieve the working pressure of the dispatching center; in addition, the present invention effectively guarantees the safety of passengers, and starts the timer to control the automatic release door at the same time after the dispatching center receives the emergency evacuation request, ensuring that passengers cannot enter and exit the train at will to reach an unknown safe area before waiting for the spare train to arrive at the faulty vehicle, and organize the passengers to evacuate in an orderly manner after the spare train transfers the passengers to the evacuation protection area.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0047] like Figure 1 The present invention provides a fully automatic emergency evacuation method for a train, comprising the following five steps:

[0048] Step S1: The driver or passenger triggers an emergency evacuation activation signal;

[0049] Step S2: the vehicle controller collects control signals;

[0050] Step S3: the vehicle controller sends different control instructions to switch the corresponding emergency evacuation mode according to the different control signals collected;

[0051] Step S4: The train or dispatching center executes the corresponding control command. After the execution is completed, the passengers are evacuated in an orderly manner according to the regulations;

[0052] Step S5: emergency evacuation mode is released.

[0053] Figure 2 This is a detailed flow chart of the present invention. When a train accident, man-made incident or other unexpected situation occurs and passengers need to be evacuated, the train driver or passenger presses any emergency handle in the cab or passenger compartment to trigger the emergency evacuation activation signal, thereby activating the train's fully automatic emergency evacuation system. The on-board controller on the train first collects control signals including the train's driving status and position to switch the corresponding emergency evacuation mode. The driving status of the train includes normal operation and abnormal operation. The normal operation of the train includes normal parking and normal driving. The abnormal operation of the train includes failure to start, failure to brake and failure to stop. The position of the train includes inside and outside the section. If the train is in the section, Figure 3 It means that no matter what running status the train is in, as long as there is at least one complete carriage in the platform area, the train is considered to be within the section. Figure 4 The train is judged to be outside the section.

[0054] According to the specific situations that require emergency evacuation of people in reality, it can be divided into four different situations, corresponding to four emergency evacuation modes. Different emergency evacuation modes execute different control instructions, as follows:

[0055] Mode 1: When the train is in the section and the driving status is normal stop or unable to start or fault stop, the train automatically releases the door to open and keep it open;

[0056] Mode 2: When the train is in the section and the driving status is normal or the brake cannot be applied, the train is immediately emergency braked, and then the train automatically releases the door to open and keep it open;

[0057] Mode 3: When the train is outside the section and the driving status is normal operation, the train is driven to the next stop platform;

[0058] Mode 4: When the train is outside the section and the driving status is unable to brake or stops due to a fault, the train will be immediately emergency braked and an emergency evacuation request signal will be sent to the dispatch center. The dispatch center will control the regional controller to demarcate the evacuation protection area and mobilize the spare train to drive to the faulty train to transfer passengers to the evacuation protection area. At the same time, the dispatch center will start the timer to temporarily take over the opening and closing of the automatic release door, and set the countdown initial value to the time it takes for the dispatch center to prepare the spare train and drive to the faulty train. During the countdown of the timer, the automatic release door remains closed. When the countdown reaches 0, the automatic release door opens and remains open.

[0059] After the train and the dispatching center have executed all control instructions, the staff will organize all passengers to evacuate in an orderly manner according to the planned emergency evacuation route. After all passengers have been evacuated, the faults will be checked and cleared. The staff will reset the emergency handles in the driver's cab and the passenger compartment. If mode four is enabled and an emergency evacuation request signal is sent to the dispatching center, the request signal will be revoked, the evacuation protection zone will be released, and the timer will be turned off.
