Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle door control, and in particular relates to a method, device, medium and vehicle for automatically prohibiting emergency unlocking of a vehicle door. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] Emergency door unlocking devices, also known as train emergency door opening devices, are used when a train's doors are unable to open after arriving at a station. Under the protection of the vehicle system, triggering the door unlocking device automatically brakes the train, requiring manual reset by a designated operator before normal operation can resume. Examples include situations where a train stops within a section and becomes unable to start or a door becomes inoperable. Previously, emergency door unlocking devices were not controlled by the driver, potentially allowing passengers to open doors on unintended sides (e.g., those not on the evacuation platform or the platform), posing a safety hazard of falling onto the tracks or receiving an electric shock. To address these situations, emergency door unlocking devices with a "request position" are gradually being introduced on subway vehicles. After a passenger activates this emergency unlocking device, the driver decides whether to allow the passenger to unlock the door. If the driver does not press the "unlock inhibit button" within a specified delay, the passenger can manually open the door. However, if the driver presses the "unlock inhibit button" within a specified delay, the door cannot be opened manually.

[0004] If a vehicle uses an emergency door unlocking device with a "request bit" and the unlocking permission is controlled solely by the driver, then for fully autonomous vehicles, emergency unlocking of the unintended door is unavoidable. Alternatively, if the driver fails to press the "unlocking prohibition button" in a timely manner due to unforeseen circumstances (e.g., physical discomfort or even fainting), the door can still be opened manually after a specified delay. This is especially true for subway systems powered by third rails. Due to the high risk of high trackside voltage (on the non-evacuation platform side), if the unlocking prohibition is not triggered by a person other than the master control, such as a passenger urgently unlocking a door on the non-evacuation platform side, a significant safety hazard (such as falling or electric shock) could arise.

In this way, the automatic prohibiting unlocking function is constructed only by a hard-wired circuit, thereby avoiding the loss of function after a network system failure.

[0054] Advantages of additional aspects of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] Figure 5 2 is a schematic diagram of another device for automatically prohibiting emergency unlocking of a vehicle door according to an embodiment of the present invention. DETAILED DESCRIPTION

[0061] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0062] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0063] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of features, steps, operations, devices, components and / or combinations thereof.

[0064] The vehicle's emergency unlocking device has three positions: reset, request (prompt), and unlock. All three positions are self-locking. The reset position is the initial position. The request position is when the emergency unlock request switch JS is triggered. When operating in this position, only the emergency unlock request switch is triggered (the normally closed contact is open), and the emergency unlock switch is not triggered, and the door is not unlocked. The emergency unlock position is the door unlock position. When operating in this position, the emergency unlock switch is triggered, and the door can be unlocked and opened.

[0065] To facilitate the emergency unlocking function, an electromagnet is added to the emergency unlocking device. When the electromagnet is energized, its pin engages the unlocking plate, allowing the emergency unlocking handle to be moved only to the requested position. When the electromagnet is de-energized, the unlocking plate is freed from the pin, allowing the emergency unlocking handle to be moved to the unlock position, unlocking the door.

[0066] according to Figure 1 The emergency unlock request switches (JS) (normally closed contacts) of all doors on the same side are hardwired in series. When a passenger operates the emergency unlock handle to the request position, the emergency unlock request switch is triggered (the normally closed contact opens). This means that when an emergency unlock request is received for a door, the emergency unlock request circuit loses power. The TCMS and signaling system then detect the unlock request signal and alert the driver via the TCMS screen. At this point, the electromagnet is energized, the unlocking disc is restrained, and the door cannot be unlocked or opened.

[0067] If the driver prohibits unlocking, he should operate the "left door prohibit unlocking" or "right door prohibit unlocking" button within 10 seconds. The prohibition signal will be given to each door, and the electromagnet will continue to be energized and attracted, and the passenger will not be able to continue to operate the unlocking.

[0068] If the driver allows unlocking, there is no need to operate the "left door prohibit unlocking" or "right door prohibit unlocking" button. After 10 seconds, the electromagnets of each door will be powered off and the passenger can continue to operate the emergency unlocking handle to the unlocking position. At this time, the emergency unlocking switch on the mechanism is triggered and the door can be unlocked and opened.

[0069] The above describes the design for disabling emergency unlocking when the vehicle is parked. If the vehicle is moving (i.e., at a speed other than zero), the door control electromagnet remains energized and engaged, the unlocking plate remains constrained, and the emergency unlocking handle can only be moved to the requested position. Therefore, when the vehicle is at a speed other than zero, the driver does not need to operate the disable unlock button, and the handle can never be moved to the unlock position. Furthermore, only the driver on the master control side can operate the disable unlock button to prevent non-master users from accidentally triggering the disable unlock.

[0070] Since the vehicle formation is arranged symmetrically, the left side of the leading car and the right side of the trailing car are on the same side. The right door train line of the leading car is the left door train line of the trailing car, and vice versa.

[0071] Example 1

[0072] according to Figure 2 and Figure 4 This embodiment provides a method for automatically prohibiting emergency door unlocking, including:

[0073] Step 1: When the vehicle is stopped and at zero speed, receive the enable signal output by the signal system.

[0074] The enable signal includes a door enable signal on the door opening side and a door enable signal on the evacuation side.

[0075] Step 2: According to the enable signal output by the signal system, determine the emergency unlocking permission state of the door on the door opening side and the evacuation side; wherein the door opening side and the evacuation side are set correspondingly.

[0076] When the signal system does not output the door enable signal on the door opening side, emergency unlocking of the door on the door opening side is automatically prohibited;

[0077] When the signal system only outputs the door enable signal on the door opening side, emergency unlocking of the door on the evacuation side is automatically prohibited.

[0078] When the vehicle is operating normally, after it stops at the platform and the door is aligned with the platform shield door, the signal system outputs the "left door enable", "right door enable" or "left and right door enable" signal according to the side of the platform, to indicate the side on which the door is allowed to be opened (where left door enable means the left door can be opened, and right door enable means the right door can be opened).

[0079] When the vehicle is in a "non-zero speed state, stopped in a non-platform area, or stopped in a platform area but the door is not aligned with the platform screen door", the signal system does not output any enable signal to prevent the door from being accidentally opened and causing danger.

[0080] If the door enable relay is energized, the relay's "normally closed contact is disconnected and the normally open contact is closed"; since the vehicle formation is symmetrical, the left side of the leading vehicle and the right side of the trailing vehicle are the same side, so if the left door enable relay of the leading vehicle is energized, the right door enable relay of the trailing vehicle will be energized, and vice versa.

[0081] Typically, the evacuation platform within the operating area is located on one side of the vehicle's forward direction. Taking the evacuation platform located on the left side of the vehicle's forward direction as an example, the implementation method of the "automatic unlocking prohibition logic" is explained:

[0082] The vehicle is completely within the operating zone. Since there is an evacuation platform on the left side of the vehicle's forward direction, emergency unlocking of the left door is permitted, while emergency unlocking of the right door is prohibited. In this operating condition, the signaling system does not output any door enable signals.

[0083] If a vehicle is partially located in the platform area (i.e., it stops a short distance from the platform (less than the full train length)), the doors are not fully aligned with the platform screen doors. To ensure safe evacuation of passengers from the evacuation platform, emergency unlocking of the left door is still permitted, while emergency unlocking of the right door is prohibited. In this condition, the signaling system does not output any door enable signals.

[0084] When the vehicle is completely within the platform area and its doors are aligned with the platform screen door, emergency unlocking is only permitted on the door opening side, regardless of the side with the evacuation platform. In this situation, the signaling system can output "Left Door Enable," "Right Door Enable," or "Both Door Enable" signals to indicate the permitted door opening side.

[0085] When the vehicle is stationary and at zero speed, the above working conditions can be expressed according to the following logic, as shown in Table 1:

[0086] Table 1 Automatically prohibit emergency door unlocking logic

[0087]

[0088] If the signal system does not output any door enable signal, emergency unlocking of the right door is prohibited;

[0089] If the signal system outputs the right door enable signal, the right side is the door opening side, and the emergency unlocking of the left door is prohibited at this time;

[0090] If the signal system outputs the left door enable signal, the left side is the door opening side, and emergency unlocking of the right door is prohibited at this time;

[0091] If the signal system outputs the left / right door enable signal at the same time, both sides are door-opening sides, and emergency unlocking of the left and right doors is not prohibited at this time.

[0092] That is: when the signal system does not output the right door enable signal, the right door emergency unlocking is prohibited; when the signal system only outputs the right door enable signal, the left door emergency unlocking is prohibited.

[0093] This embodiment determines the emergency unlocking permission status of the doors on the door opening side and the evacuation side according to the enable signal output by the signal system, and can automatically prohibit the emergency unlocking of the doors on the undesired side to avoid the occurrence of safety hazards.

[0094] Example 2

[0095] like Figure 5 As shown, this embodiment provides a device for automatically prohibiting emergency unlocking of a vehicle door, which includes:

[0096] (1) An enabling signal receiving module, which is used to receive the enabling signal output by the signal system when the vehicle is stopped and at zero speed.

[0097] (2) an emergency unlocking judgment module, which is used to judge the emergency unlocking permission state of the vehicle door on the door opening side and the evacuation side according to the enable signal output by the signal system; wherein the door opening side and the evacuation side are set correspondingly;

[0098] When the signal system does not output the door enable signal on the door opening side, emergency unlocking of the door on the door opening side is automatically prohibited; when the signal system only outputs the door enable signal on the door opening side, emergency unlocking of the door on the evacuation side is automatically prohibited.

[0099] When the vehicle is in a non-zero speed state, stops in a non-platform area, or stops in a platform area but the door is not aligned with the platform screen door, the signal system does not output any enable signal.

[0100] When the vehicle is completely within the operating range, the signal system does not output any enable signal;

[0101] When the vehicle is partially located in the platform area, the signal system does not output any enable signal;

[0102] When the vehicle is completely located in the platform area and the door is completely aligned with the platform screen door, the signal system outputs the door enable signal of the preset side.

[0103] It should be noted here that the various modules in this embodiment correspond one-to-one to the various steps in Example 1, and the specific implementation processes are the same, which will not be repeated here.

[0104] This embodiment determines the emergency unlocking permission status of the doors on the door opening side and the evacuation side according to the enable signal output by the signal system, and can automatically prohibit the emergency unlocking of the doors on the undesired side to avoid the occurrence of safety hazards.

[0105] Example 3

[0106] This embodiment provides a device for automatically prohibiting emergency unlocking of a vehicle door, which includes: a network system and a logic control unit;

[0107] The logic control unit is used to:

[0108] When the vehicle is stopped and at zero speed, the enable signal output by the receiving signal system is received;

[0109] According to the enable signal output by the signal system, the emergency unlocking permission state of the door on the door opening side and the evacuation side is determined; wherein the door opening side and the evacuation side are set correspondingly;

[0110] When the signal system does not output the door enable signal on the door opening side, emergency unlocking of the door on the door opening side is automatically prohibited;

[0111] When the signal system only outputs the door enable signal on the door opening side, emergency unlocking of the door on the evacuation side is automatically prohibited;

[0112] The network system is used to send the door emergency unlocking permission status output by the logic control unit to each door.

[0113] When the vehicle is in a non-zero speed state, stops in a non-platform area, or stops in a platform area but the door is not aligned with the platform screen door, the signal system does not output any enable signal.

[0114] When the vehicle is completely within the operating range, the signal system does not output any enable signal;

[0115] When the vehicle is partially located in the platform area, the signal system does not output any enable signal;

[0116] When the vehicle is completely located in the platform area and the door is completely aligned with the platform screen door, the signal system outputs the door enable signal of the preset side.

[0117] This embodiment uses a logic control unit instead of a relay, collects the enable signals of each side door through the input port, and outputs them after determining the unlocking prohibition logic, thereby realizing the functions represented by the contacts of each side door enable relay in the hardware circuit.

[0118] Example 4

[0119] like Figure 3 As shown, this embodiment provides a device for automatically prohibiting emergency unlocking of a vehicle door, which includes: an emergency unlocking request switch, an enabling relay, and a prohibiting unlocking switch;

[0120] Connect the normally closed contacts of the emergency unlock request switches of each door on the same side in series through hard wiring;

[0121] The enabling relay on the door opening side - the normally closed contact bypasses the unlocking prohibition switch on the door opening side;

[0122] After the enabling relay-normally open contact on the door opening side and the enabling relay-normally closed contact on the evacuation side are connected in series, the unlock prohibition switch on the evacuation side is bypassed.

[0123] According to the unlocking prohibition logic of Example 1, by using the "right door enable relay - normally closed contact" to bypass the "right door unlock prohibition button," the right door emergency unlocking function is disabled when the signaling system does not output the right door enable signal. By using the "right door enable relay - normally open contact + left door enable relay - normally closed contact" to bypass the "left door unlock prohibition button," the left door emergency unlocking function is disabled when the signaling system only outputs the right door enable signal. This automatic unlocking prohibition function is implemented solely through hard-wired circuitry, preventing loss of functionality in the event of a network system failure.

[0125] This embodiment provides a computer-readable storage medium having a computer program stored thereon. When the program is executed by a processor, the steps of the method for automatically prohibiting emergency unlocking of a vehicle door as described in the first embodiment above are implemented.

[0130] When the signal system does not output the door enable signal on the door opening side, emergency unlocking of the door on the door opening side is automatically prohibited;

[0131] When the signal system only outputs the door enable signal on the door opening side, emergency unlocking of the door on the evacuation side is automatically prohibited.

[0132] It should be noted here that the various steps in the emergency unlocking control device correspond one-to-one to the various steps in Example 1, and the specific implementation process is the same, which will not be repeated here.
