[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present application.

[0046] The core of the present application is to provide a method, device, equipment and rail vehicle for implementing the unattended vigilance function of a train, so as to solve the problem that the current implementation method of the unattended vigilance function of a train is single and may affect the driving safety when the driver performs multiple operations.

[0047] In order to enable those skilled in the art to better understand the solution of the present application, the following will further elaborate on the present application in conjunction with the drawings and specific embodiments.

[0048] Figure 1 It is a flowchart of a method for implementing the unattended vigilance function of a train provided by an embodiment of the present application. As Figure 1 shown, the method includes:

[0049] S10: Monitor the train control signal during the running of the train.

[0050] Among them, the train control signal is the control signal output by various control devices manipulated by the driver in the train.

[0051] There is a Central Control Unit (CCU) inside the train, which is responsible for activating or shielding the unattended vigilance function. In this embodiment, the CCU is also responsible for monitoring the train control signals during the operation of the train.

[0052] It should be noted that in this embodiment, the train control signals are the control signals output by various control devices manipulated by the driver in the train. The control signals output by other control devices not manipulated by the driver are not considered train control signals, so as to ensure that the train control signals can be used as the criterion for resetting the unattended vigilance time. In this embodiment, the specific types of the control devices involved are not limited. For example, they can be toggle switches, knobs or buttons on the driver's console, driver controllers, etc., depending on the specific implementation situation.

[0053] S11: Determine whether any train control signal is collected within the unattended vigilance time; if so, go to step S12; if not, go to step S13.

[0054] S12: Reset the unattended vigilance time and return to step S11;

[0055] S13: Trigger the unattended vigilance alarm until the train stops.

[0056] Furthermore, the CCU determines whether any train control signal is collected within the unattended vigilance time. It can be understood that since the train control signals are the control signals output by various control devices manipulated by the driver in the train, when any control signal output by a control device manipulated by the driver in the train is collected, it can be considered that the driver is currently in a normal state and the unattended vigilance time can be reset. After the unattended vigilance time is reset, return to step S11 to perform the next round of collection and judgment of train control signals. When no control signals output by the control devices manipulated by the driver in the train are collected, it is considered that the driver may have lost the ability to control the train, trigger the unattended vigilance alarm, and at the same time the train brakes until the train stops. In this embodiment, the unattended vigilance alarm method and the specific braking process are not limited and depend on the specific implementation situation.

[0057] In this embodiment, the train control signals during the operation of the train are monitored; wherein, the train control signals are the control signals output by various control devices manipulated by the driver in the train; it is determined whether any train control signal is collected within the unattended vigilance time; if so, the unattended vigilance time is reset, and the process returns to the step of determining whether a train control signal is collected within the unattended vigilance time; if not, the unattended vigilance alarm is triggered until the train stops. It can be seen that in this solution, the control signals output by various control devices manipulated by the driver in the train are regarded as the normal activities of the driver and used as the basis for resetting the unattended vigilance time; when any train control signal is collected, the unattended vigilance time can be reset, otherwise the unattended vigilance alarm is triggered until the train stops. Since it is not limited to the traditional specified reset methods such as the unattended vigilance button, the specified reset actions of the driver are effectively reduced, and the driving safety of the driver during multiple operations is improved.

[0058] Based on the above embodiment, in some embodiments, triggering the unattended vigilance alarm until the train stops includes:

[0059] S131: Determine whether a braking signal output by the driver controller is monitored; if not, proceed to step S132; if so, proceed to step S133.

[0060] S132: Trigger an audible and visual alarm, and control the train to perform the maximum service braking after a first preset time, and control the train to perform the emergency braking after a second preset time.

[0061] S133: Determine the current braking level of the train.

[0062] S134: Extend the unattended vigilance time according to the current braking level.

[0063] S135: When the extended unattended vigilance time is reached, trigger an audible and visual alarm until the train stops.

[0064] It can be understood that when the unattended vigilance alarm is triggered, the train needs to brake. On this basis, in order to reduce the number of driver operations and improve the driver's driving attention, in this embodiment, it is specifically determined whether a braking signal output by the driver controller is monitored. The driver controller is the main control electrical appliance used by the train driver to operate the train. It indirectly controls the electrical equipment of the main circuit through the low-voltage electrical appliances of the control circuit. The driver sends a braking signal to the train braking control system by operating the brake handle of the driver controller, and the train can be braked.

[0065] If it is confirmed that no braking signal output by the driver controller is detected, it is considered that the current train has not applied braking, and it is necessary to trigger an audible and visual alarm to promptly remind the driver or other staff to check the current state of the train, and control the train to execute the maximum service braking after the first preset time, and control the train to execute the emergency braking after the second preset time, and finally stop the train. It should be noted that in this embodiment, there are no restrictions on the first preset time and the second preset time. For example, when the unattended vigilance time is 30 s, the first preset time can be set to 35 s and the second preset time can be set to 40 s; that is, when the timing reaches 30 s, an audible and visual alarm is triggered, when the timing reaches 35 s, the train executes the maximum service braking, and when the timing reaches 40 s, the train executes the emergency braking.

[0066] If it is confirmed that the braking signal output by the driver controller is detected, it is considered that the current train has applied braking, and the current braking level of the train can be further determined, and the unattended vigilance time can be extended according to the current braking level. Finally, when the extended unattended vigilance time is reached, an audible and visual alarm is triggered until the train stops. This reduces the number of operations of the driver when the train is braking and improves the driver's driving attention. In this embodiment, there are no restrictions on the specific method of extending the unattended vigilance time according to the current braking level, which is determined according to the specific implementation situation.

[0067] In this embodiment, if no braking signal output by the driver controller is detected, an audible and visual alarm is triggered, and the train is controlled to execute the maximum service braking after the first preset time, and the train is controlled to execute the emergency braking after the second preset time; if the braking signal output by the driver controller is detected, the current braking level of the train is determined; the unattended vigilance time is extended according to the current braking level; when the extended unattended vigilance time is reached, an audible and visual alarm is triggered until the train stops, effectively reducing the number of operations of the driver and improving the driver's driving attention.

[0068] Based on the above embodiments, in some embodiments, extending the unattended vigilance time according to the current braking level includes:

[0069] S136: Obtain the unattended vigilance extension time corresponding to each braking level of the train.

[0070] Among them, the unattended vigilance extension time corresponding to each braking level increases in the order of each braking level.

[0071] S137: Determine the unattended vigilance extension time corresponding to the current braking level according to the unattended vigilance extension time corresponding to each braking level.

[0072] S138: Add the unattended vigilance time and the unattended vigilance extension time corresponding to the current braking level to obtain the extended unattended vigilance time.

[0073] Trains generally have 8 braking levels: B1 - B7, and EB. Among them, B1 - B7 are service braking levels, used for the daily deceleration and stopping operations of the train; B1 represents weak service braking with the minimum braking force, B4 represents medium service braking, and B7 represents maximum service braking with the maximum braking force. While EB is the emergency braking level, used to quickly stop the train in case of an emergency. Emergency braking is usually triggered by the driver through devices such as the emergency braking button or mushroom head switch, and will apply the maximum braking force. In this application, corresponding unattended vigilance extension times are pre - set for each braking level, and the unattended vigilance extension times corresponding to each braking level increase in the order of each braking level. In this embodiment, there is no limit to the increasing method of each unattended vigilance extension time. For example, it can increase according to an arithmetic progression rule, or it can increase according to a geometric progression rule, depending on the specific implementation situation. In some embodiments, the unattended vigilance extension times corresponding to braking levels B1 - B7 and EB can be set to 2s, 4s, 6s, 8s, 10s, 12s, 14s, and 16s respectively.

[0074] Therefore, in order to extend the unattended vigilance time, first obtain the unattended vigilance extension times corresponding to each braking level of the train. According to the unattended vigilance extension times corresponding to each braking level, determine the unattended vigilance extension time corresponding to the current braking level. Finally, add the unattended vigilance time and the unattended vigilance extension time corresponding to the current braking level to obtain the extended unattended vigilance time. For example, assume that the unattended vigilance extension time corresponding to the current braking level B2 is 4s and the unattended vigilance time is 30s, then the extended unattended vigilance time is 34s. In this way, the extension of the unattended vigilance time is achieved.

[0075] In order to avoid the audible and visual alarms triggered by the unattended vigilance function from interfering with the driver's normal driving, based on the above - mentioned embodiment, in some embodiments, before monitoring the train control signal during the train operation, it further includes:

[0076] S14: Determine whether the running speed of the train reaches the preset speed; if so, activate the unattended vigilance function of the train and enter step S10; if not, keep the unattended vigilance function of the train closed.

[0077] Specifically, before monitoring the train control signal during the train operation, it is also necessary to determine whether the running speed of the train reaches the preset speed. In this embodiment, there is no limit to the preset speed. Generally, it is considered that there is no significant safety risk when the train is running at a low speed, such as below 5 km / h. Therefore, if it is confirmed that the running speed of the train reaches the preset speed, then activate the unattended vigilance function of the train and enter the step of monitoring the train control signal during the train operation; if not, keep the unattended vigilance function of the train closed, thus avoiding the audible and visual alarms triggered by the unattended vigilance function from interfering with the driver's normal driving.

[0078] In addition, considering that the ultimate protection strategy for unattended vigilance also triggers the emergency braking of the train to stop. Therefore, when the train is in the emergency braking state, the unattended vigilance function of the train should be blocked. Otherwise, due to the audible and visual alarms triggered by the unattended vigilance function, it will continuously interfere with the driver.

[0079] In order to improve the control efficiency of train operation, based on the above embodiments, in some embodiments, the control device in the train includes a Human Machine Interface (HMI) display screen.

[0080] Specifically, the HMI display screen is used to receive the driver's voice control instructions and / or screen touch instructions, and convert the voice control instructions and / or screen touch instructions into corresponding control signals and output them to the corresponding devices. The following are several control items of the HMI display screen:

[0081] Table 1 HMI Display Screen Control Item Table

[0082]

[0083] As shown in Table 1, the HMI display screen can implement interface operations, interface switching, input of voice control instructions and / or screen touch instructions, and realize the control of various functions in the train.

[0084] Based on the above embodiments, in some embodiments, the control device at least includes a lighting control device, a train operation auxiliary control device, a train safety and emergency control device, a train operation control device, a car and equipment control device, and a signal communication device. The following is a specific description:

[0085] Table 2 Driver's Cab Console Control Device Table

[0086]

[0087] As shown in Table 2, the control devices manipulated by the driver involved in this application at least include the following types:

[0088] (1) Lighting control device, including the driver's cab light rotary switch and the headlight rotary switch, used to control the internal lighting of the driver's cab and the lighting equipment at the front end of the train to ensure clear vision of the driver in different environments; sunshade rotary switch: used to control the lifting of the sunshade in the driver's cab to prevent strong light from interfering with the driver's vision.

[0089] (2)Train operation auxiliary control device, including a wiper rotary switch for controlling the start, stop and speed adjustment of the train windshield wiper to ensure clear visibility for the driver under adverse weather conditions such as rainy days; a whistle selection rotary switch for selecting the tone or mode of the train whistle to emit warning signals; and a vigilance button for the driver to operate and confirm to prevent the driver from being fatigued or inattentive during driving and ensure the safe operation of the train.

[0090] (3)Train safety and emergency control device, including an emergency brake mushroom head for quickly applying emergency brakes in case of emergencies to ensure the train stops within the shortest time and guarantee the safety of train operation; an emergency reset button for resetting the train system in case of emergency brakes or other emergencies to restore the normal operation state of the train; and a tunnel hydrogen shutdown button for shutting down the hydrogen system (such as in a hydrogen fuel cell train) when running in a tunnel to prevent safety hazards caused by hydrogen leakage.

[0091] (4)Train operation control device, including a direction handle for controlling the running direction of the train (forward, backward or neutral), which is a basic operation component for train operation; a controller handle for controlling the traction and braking of the train, and realizing speed control and braking force adjustment of the train by adjusting the position of the handle; a sanding switch for controlling the train sanding device to increase the friction between the wheel and the rail by sanding to prevent wheel spin or skid, especially under wet rail conditions; and a reset button for resetting certain systems or equipment of the train to solve equipment failures or abnormal states.

[0092] (5)Carriage and equipment control device, including an electric heater for controlling the electric heater equipment in the driver's cab or carriage to provide a heating function and ensure a suitable temperature in the driver's cab or carriage; door opening and closing related buttons for controlling the opening and closing of the train doors, including a centralized door opening and closing button and a single - side door opening and closing button to ensure the safe boarding and alighting of passengers; and a footrest for placing the driver's feet to provide a comfortable operating posture.

[0093] (6)Signal communication device, including an electric whistle button for controlling the electric whistle of the train to emit warning signals to alert pedestrians, vehicles or other trains.

[0094] It can be understood that the control signals output by the above - mentioned control devices need to be collected. Except for the door opening and closing related buttons, the emergency reset button and the direction handle, the control signals of the remaining control devices can be used as criteria for resetting the vigilance time.

[0095] In addition, to further reduce the impact of the unattended vigilance reset on the driver's normal driving process, an intelligent monitoring system can also be introduced on the train. By using biosensors (such as cameras and heart rate monitors) to detect the driver's status in real time, the driving safety can be effectively improved. The camera analyzes the driver's facial features (such as blink frequency and head posture) to judge fatigue or distraction; the heart rate monitor tracks the physiological state in real time through wearable devices. When the detection result is normal, the unattended vigilance time is directly reset. When an abnormality is detected, the system starts a hierarchical warning, including a primary reminder: a sound prompt or a screen pop-up window to remind the driver to concentrate; a secondary reminder: vibrating the seat or the steering wheel to provide tactile feedback; a tertiary reminder: if the driver does not respond, the system automatically decelerates and links with the dispatching center, and triggers emergency braking if necessary. This hierarchical warning mechanism can not only intervene in potential risks in a timely manner but also avoid excessive interference with normal driving, significantly improving safety and the driver's concentration.

[0096] In the above embodiments, the execution method of the train unattended vigilance function is described in detail. The present application also provides an embodiment corresponding to the execution device of the train unattended vigilance function.

[0097] Figure 2 The following is a schematic diagram of an execution device for the train unattended vigilance function provided by an embodiment of the present application. As Figure 2 shown, the device includes:

[0098] A monitoring module 10 for monitoring the train control signals during the running of the train; wherein, the train control signals are the control signals output by various control devices manipulated by the driver in the train;

[0099] A judgment module 11 for judging whether any train control signal is collected within the unattended vigilance time; if so, triggering a reset module 12; if not, triggering an alarm module 13;

[0100] A reset module 12 for resetting the unattended vigilance time and triggering the judgment module 11;

[0101] An alarm module 13 for triggering the unattended vigilance alarm until the train stops.

[0102] Since the embodiments of the device part correspond to the embodiments of the method part, for the embodiments of the device part, please refer to the description of the embodiments of the method part, and will not be elaborated here for the time being.

[0103] In this embodiment, the execution device of the train unmanned alert function includes a monitoring module, a judgment module, a reset module and an alarm module. The device can monitor the train control signal of the train during operation; wherein the train control signal is a control signal output by a variety of control devices controlled by the driver in the train; judge whether any train control signal is collected within the unmanned alert time; if so, reset the unmanned alert time and return to the step of judging whether the train control signal is collected within the unmanned alert time; if not, trigger the unmanned alert alarm until the train stops. It can be seen that this scheme regards the control signals output by a variety of control devices controlled by the driver in the train as the normal activities of the driver and as the basis for resetting the unmanned alert time; when any train control signal is collected, the unmanned alert time can be reset, otherwise the unmanned alert alarm is triggered until the train stops. Since it is not limited to the traditional designated reset methods such as the unmanned alert button, it effectively reduces the driver's designated reset actions and improves the driving safety of the driver when performing various operations.
