Description

Technical Field

[0001] This utility model relates to the field of high-speed train technology, and in particular to a high-speed train anti-misoperation door control system. Background Technology

[0002] The driver's cab of a high-speed train is equipped with multiple door control buttons, such as the left door release button, left door open button, left door close button, right door release button, right door open button, and right door close button. When the train arrives at a station, the train conductor manually determines whether the platform is to the left or right of the train and presses the corresponding left or right door control button to open the left or right door for passenger passage. Because the conductor's subjective judgment of the door opening direction sometimes results in the door opening in the wrong direction, posing a significant safety hazard to passengers.

[0003] To address the aforementioned issues, Chinese Patent Publication No. CN221563048U discloses a high-speed train door opening and closing reminder device. This device features a cover surrounding the door control buttons, with a housing movably connected to the cover. The housing has a covering position for sealing clearance holes and an opening position for clearing clearance holes along its travel. An indicator module on the housing indicates the door control button to be operated, and this indicator module is controlled by the recognition result of a voice recognition module. This patent, through voice recognition, identifies the broadcast message indicating "open left door" or "open right door" and controls the corresponding indicator module to display the prompt to the train attendant, thus preventing accidental operation to some extent. However, when the environment inside the high-speed train is noisy, voice recognition may not accurately identify the "open left door" or "open right door" message, leading to the possibility of incorrect indication by the indicator module. Furthermore, this patent only instructs the train attendant through the indicator module and does not prevent the attendant from opening the housing and operating the button. If the attendant is distracted or nervous and ignores the indicator module's instructions, there is still a possibility of incorrect operation of the door control button. Utility Model Content

[0004] This utility model aims to solve the technical problem of the risk of train doors opening in the wrong direction in the existing technology, and provides a train door anti-misoperation control system that can effectively prevent train doors from opening in the wrong direction.

[0005] To achieve the above-mentioned objectives of this utility model, this utility model provides a high-speed train anti-misoperation door control system, comprising: at least one first arrival sensor installed on the left side of the high-speed train; at least one second arrival sensor installed on the right side of the high-speed train; a sound receiver for receiving sound signals inside the high-speed train; at least two button protection mechanisms, each correspondingly covering the periphery of at least two door control buttons; a main module, wherein the first signal input terminal of the main module is connected to the output terminal of the first arrival sensor, the second signal input terminal of the main module is connected to the output terminal of the second arrival sensor, the third signal input terminal of the main module is connected to the output terminal of the sound receiver, and the control signal output terminal of the main module is connected to the control signal input terminal of the button protection mechanism.

[0006] The above technical solution involves using a first and second arrival sensor to detect platform information on both sides of the train. The main module can initially determine the platform direction using the output signals from the first and second arrival sensors. Simultaneously, it collects sound signals from inside the train through a sound receiver, performs voice recognition processing on the sound signals to extract key information on whether to open the left or right door, and then integrates this with the previously determined platform direction to accurately determine the door opening direction. This avoids the problem of incorrect door opening due to voice recognition errors caused by noise inside the train, and effectively prevents the train from opening the wrong door.

[0007] In a preferred embodiment of this utility model, the host module is connected to the button protection mechanism via a communication interface.

[0008] The above technical solution enables reliable and stable information transmission.

[0009] In a preferred embodiment of this utility model, the button protection mechanism includes a cover structure surrounding the door control button and a drive module controlled by the host module; the cover structure includes a base and a button cover movably connected to the base, the base having a button hole for accommodating the door control button; the drive module is used to drive the button cover to rotate relative to the base to cover or expose the button hole, or the drive module is used to lock or release the relative movement between the button cover and the base.

[0010] The above technical solution: The button protection mechanism uses a drive module to drive the button cover to rotate relative to the base to cover or expose the button hole, realizing automated control. It eliminates the need for train operators to manually open the button cover, avoiding accidental operation of the button by train operators, thereby improving the accuracy of the train's door opening. The button protection mechanism uses a drive module to lock or release the relative movement between the button cover and the base, preventing train operators from opening the control button of a door that has not been identified as needing to be opened, thereby effectively preventing accidental operation of the button by train operators and improving the accuracy of the train's door opening.

[0011] In a preferred embodiment of this utility model, when the drive module is used to drive the button cover to rotate relative to the base to cover or expose the button hole, the base and the button cover are rotatably connected by a rotating shaft; the drive module includes a drive motor and a transmission mechanism, the transmission mechanism is used to convert the rotation of the motor shaft of the drive motor into the rotation of the rotating shaft, and the drive motor is controlled by the host module.

[0012] The above technical solution adopts a motor drive method, which makes it easy to control the forward and reverse rotation of the button cover by rotating the motor shaft. The control is simple and easy to implement.

[0013] In a preferred embodiment of this utility model, the transmission mechanism includes a worm gear structure and at least one cascaded gear transmission pair; the worm gear structure includes a worm coaxially connected to the motor shaft and a worm gear meshing with the worm, the worm gear being coaxially mounted with the input gear of the first-stage gear transmission pair, and the output gear of the last-stage gear transmission pair being sleeved outside the rotating shaft.

[0014] The above technical solution adopts a combination of worm gear and cascaded gear transmission pairs, which can increase torque, make the structure compact, reduce the space occupied by the transmission mechanism, and facilitate installation on the control panel of the EMU driver's cab.

[0015] In a preferred embodiment of this utility model, the transmission mechanism includes a worm gear structure, at least one stage gear transmission pair, and a magnetic drive pair; the worm gear structure includes a worm coaxially connected to the motor shaft and a worm meshing with the worm, the worm being coaxially mounted with the input gear of the first stage gear transmission pair, the output gear of the last stage gear transmission pair being coaxially mounted with the driving magnetic wheel of the magnetic drive pair, and the passive magnetic wheel of the magnetic drive pair being sleeved outside the rotating shaft.

[0016] The above technical solution uses a combination of worm gear and cascaded gear transmission pairs to increase torque, make the structure compact, reduce the space occupied by the transmission mechanism, and also uses a magnetic transmission pair as the last stage of transmission pair to achieve contactless transmission, so that the transmission mechanism will not be damaged when the button cover is opened manually.

[0017] In a preferred embodiment of this utility model, when the drive module is used to lock or release the relative movement between the button cover and the base, the button cover is rotatably connected to the base, and the button cover is flipped to cover or expose the button hole; the drive module includes a first locking body located on the button cover, a second locking body located on the base that cooperates with the first locking body, and a locking control module controlled by the host module to control the connection state of the first locking body and the second locking body.

[0018] The above technical solution involves manually flipping the button cover to cover or expose the button hole. The connection between the first and second lock bodies is locked or released by the locking module. When the locking module locks the connection between the first and second lock bodies, the train operator cannot flip the button cover. When the locking module releases the connection between the first and second lock bodies, the train operator can flip the button cover. This can prevent the train operator from accidentally flipping the button cover to operate the door control buttons.

[0019] In a preferred embodiment of this utility model, when the drive module is used to lock or release the relative movement between the button cover and the base, the button cover and the base are slidably connected, and the button cover is slidable to cover or expose the button hole; the sliding stroke of the button cover is provided with a covering position that completely covers the button hole; the drive module includes a first locking body located on the button cover, a second locking body located on the base that cooperates with the first locking body when the button cover is in the covering position, and a locking control module controlled by the host module to control the connection state of the first locking body and the second locking body. 。

[0020] The above technical solution involves manually sliding the button cover to cover or expose the button hole, and locking or releasing the connection between the first lock body and the second lock body through the locking module. When the locking module locks the connection between the first lock body and the second lock body, the train operator cannot slide the button cover. When the locking module releases the connection between the first lock body and the second lock body, the train operator can slide the button cover, which can prevent the train operator from accidentally sliding the button cover to operate the door control button.

[0021] In a preferred embodiment of this utility model, the button protection mechanism further includes a processor; the processor is provided with a communication interface, which connects and communicates with the host module and sends control commands to the drive module.

[0022] The above technical solution enables high-speed and reliable communication between the host module and the button protection mechanism through a communication interface.

[0023] In a preferred embodiment of this utility model, the button protection mechanism further includes an indicator module connected to the processor.

[0024] The above technical solution instructs train operators to operate the equipment, improving operational accuracy and convenience. Attached Figure Description

[0035] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0036] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] In the description of this utility model, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0038] This utility model discloses a control system for preventing misaligned doors on high-speed trains. In a preferred embodiment, such as... Figure 1 As shown, the train set's anti-misoperation door control system includes:

[0039] At least one first arrival sensor is installed on the left side of the EMU;

[0040] At least one second arrival sensor is installed on the right side of the EMU;

[0041] A sound receiver is used to receive sound signals inside the high-speed train.

[0042] At least two button protection mechanisms are respectively installed around at least two door control buttons;

[0043] The main module has its first signal input terminal connected to the output terminal of the first arrival sensor, its second signal input terminal connected to the output terminal of the second arrival sensor, its third signal input terminal connected to the output terminal of the sound receiver, and its control signal output terminal connected to the control signal input terminal of the button protection mechanism. The main module is used to issue control commands to the braking control mechanism.

[0044] In this embodiment, the first and second arrival sensors are preferably, but not limited to, installed on the side windows or the lower part of the train body near the wheels. Since the platform height is greater than the train track height, the first and second arrival sensors can be distance sensors used to measure the distance from the train body to objects on either side. Therefore, the first and second arrival sensors are preferably, but not limited to, existing millimeter-wave radar sensors, ultrasonic radar sensors, laser distance sensors, or ultrasonic distance sensors. The first and second arrival sensors can also be reflective photoelectric switches. The light emitting unit of the reflective photoelectric switch emits light signals in real time. When the train enters the station, the platform side reflects the light signal to the light receiving unit. Before the train enters the station, the light receiving unit cannot receive the light signal, thus identifying whether the train has arrived and whether the platform is on the left or right side. The first / second arrival sensor can be installed only at the front of the train, or multiple sensors can be installed at the front, rear, and middle of the train. The first and second arrival sensors are preferably, but not limited to, connected to the train body using suction cups, adhesive, or welding.

[0045] In this embodiment, such as Figure 2 As shown, the first and second arrival sensors can also be platform cameras located on the left and right sides of the train's front, or behavior recognition cameras located in the driver's cab. The host module can use existing target recognition algorithms to identify the platform name and building based on images captured by the platform cameras, thereby obtaining information about whether the platform is on the left or right side. The host module can also use existing motion recognition algorithms to identify train attendant movements based on images captured by the behavior recognition cameras, obtaining information about whether the platform is on the left or right side. It should be noted that the above image processing algorithms are all existing technologies and are not within the protection scope of this utility model.

[0046] In this embodiment, the sound receiver is preferably, but not limited to, a pickup or microphone, used to convert sound signals into electrical or digital signals. The sound receiver can be installed inside the carriage to collect broadcast voice signals or installed in the driver's cab to collect voice commands from the train conductor.

[0047] In this embodiment, button protection mechanisms can be configured according to the number of door control buttons on the train set. Door control buttons generally include six buttons: release left door button, open left door button, close left door button, release right door button, open right door button, and close right door button. When it is necessary to open the left / right door, the release left / right door button must be operated first to release the left / right door before the open left / right door button can be operated. Therefore, only two button protection mechanisms can be configured, correspondingly covering the release left and right door buttons respectively; alternatively, more than two button protection mechanisms can be configured, such as one button protection mechanism for each of the six door control buttons, as needed. Only one button protection mechanism covers the entire outer perimeter of another button protection mechanism.

[0048] In this embodiment, the button protection mechanism can adopt the structure disclosed in the background art of Chinese Patent No. CN221563048U. This structure includes a housing covering the door control button and an indicator module on the housing. After the train operator removes the housing according to the indication information of the indicator module, he operates the door control button below. After the operation is completed, the housing is put back over the door control button.

[0049] In this embodiment, such as Figure 2As shown, the host module may include a main controller, which is a microprocessor, preferably but not limited to the Aichip Yuanzhi AX650N. The main controller has an internal data storage unit that can load existing voice recognition and image recognition programs, and can recognize train attendant actions through the image recognition program. The main controller can be connected to the output terminals of the first arrival sensor, the second arrival sensor, and the sound receiver via A / D pins or a data interface (such as a UART serial port). The main controller compares the output signals of the first and second arrival sensors with preset signal thresholds (corresponding to a distance threshold), and obtains a preliminary result of whether it is the left or right platform based on the comparison result. The main controller uses the existing voice recognition program to identify the keyword "left platform" or "right platform" from the sound signal received by the sound receiver. When the preliminary result matches the keyword, the main controller sends a control command to the button protection mechanism around the corresponding door control button via an RS485 communication interface or a wireless communication interface, causing it to open the button cover and / or cause the indicator module to indicate and remind the train attendant. If the two do not match, the main controller does not send any command. It should be noted that in the above-mentioned main controller processing, the determination of whether the preliminary result is consistent with the keyword can be made using the AND operation principle. The AND operation principle is a conventional processing method in this field. For example, Chinese patents with publication numbers CN101673940A and CN109060080A both involve technical solutions for performing AND operations on two signals to obtain a new signal. Therefore, the method involved in the main controller processing is a relatively conventional processing method in this field and is not within the protection scope of this utility model.

[0050] In this embodiment, the functions of the host module can also be executed through hardware, specifically, such as... Figure 3As shown, the host module includes a voice recognition module, a first comparator, a second comparator, a reference power supply, a first AND gate unit, a second AND gate unit, and a main controller. The output of the first arrival sensor is connected to the positive input of the first comparator, the output of the reference power supply is connected to the negative input of the first comparator, the output of the first comparator is connected to the first input of the first AND gate unit, the left platform detection terminal of the voice recognition module is connected to the second input of the first AND gate unit, and the output of the first AND gate unit is connected to the first detection terminal of the main controller. The output of the second arrival sensor is connected to the positive input of the second comparator, the output of the reference power supply is connected to the negative input of the second comparator, the output of the second comparator is connected to the first input of the second AND gate unit, the right platform detection terminal of the voice recognition module is connected to the second input of the second AND gate unit, and the output of the second AND gate unit is connected to the second detection terminal of the main controller. The main controller sends control commands to each button protection structure. The preferred, but not limited to, models of the first and second comparators are LM324 and LM358, and the preferred, but not limited to, models of the first and second AND gate units are 74LS08 and 74HC08.

[0051] Figure 3In this system, the voice recognition module can be a microprocessor loaded with existing voice recognition software. It processes the audio signal output from the sound receiver to identify the keywords "left platform" or "right platform." Two I / O interfaces are used to represent whether the keywords "left platform" and "right platform" have been detected, using high and low voltage levels respectively. When the keyword "left platform" is detected, the left platform detection terminal (one I / O interface) of the voice recognition module outputs a high level, and the right platform detection terminal (the other I / O interface) outputs a low level. When the keyword "right platform" is detected, the right platform detection terminal outputs a high level, and the left platform detection terminal outputs a low level. The reference power supply is a power supply circuit that outputs a reference voltage. The reference voltage can be 0V or adjusted empirically, used to determine whether the output signals of the two arrival sensors are arrival signals or non-arrival information. If it is the left platform, the output signal of the first arrival sensor is greater than the reference power supply signal, the first comparator outputs a high level, and the second comparator outputs a low level. If the voice recognition module detects "left platform," the left platform detection terminal of the voice recognition module outputs a high level, and the first AND gate unit also outputs a high level. Upon receiving this high level, the main controller sends a control command to the button protection mechanism surrounding the door control button corresponding to the left door. If the voice recognition module does not detect "left platform," the left platform detection terminal of the voice recognition module outputs a low level, and the first AND gate unit also outputs a low level. Upon receiving this low level, the main controller will not send a control command to the button protection mechanism surrounding the door control button corresponding to the left door. The button protection process for the right door can be described as above and will not be repeated here. It should be noted that the method of the main controller sending control commands to the corresponding button protection mechanism based on the detection signal is existing, such as the method in Chinese Patent Publication No. CN221563048U, which controls the corresponding housing indicator module based on the voice recognition result, and is not within the scope of protection of this utility model.

[0052] In a preferred embodiment, the host module communicates with the button protection mechanism via a communication interface. The communication interface can be a wired interface or a wireless interface, and the button protection mechanism is correspondingly equipped with wired and wireless interfaces. The wired interface is preferably, but not limited to, an RS485 or RS232 interface, and the wireless interface is preferably, but not limited to, a Wi-Fi module, a 4G module, and a 5G module, all of which are equipped with antennas.

[0053] In a preferred embodiment, the button protection mechanism includes a processor 5, which may be a microprocessor such as a microcontroller. Figure 4As shown, the processor 5 is equipped with a communication interface, which connects and communicates with the host module. The communication interface can be a wired interface or a wireless interface. The button protection mechanism also includes an indicator module 6 connected to the processor 5. The indicator module 6 is preferably, but not limited to, an indicator light mounted on the base 3, which can be a green light or a red light.

[0054] In a preferred embodiment, the button protection mechanism includes a cover structure surrounding the door control button, and a drive module controlled by the host module; such as Figure 5 and Figure 6 As shown, the cover structure includes a base 3 and a button cover 1 movably connected to the base 3. The base 3 has a button hole 7 for accommodating door control buttons; the drive module is used to drive the button cover 1 to rotate relative to the base 3 to cover or expose the button hole 7. Figure 7 As shown, the base 3 and the button cover 1 are rotatably connected via a rotating shaft 2; the drive module includes a drive motor 8 and a transmission mechanism 4, the transmission mechanism 4 being used to convert the rotation of the motor shaft of the drive motor 8 into the rotation of the rotating shaft 2, and the drive motor 8 is controlled by the host module. When the button protection mechanism includes a processor 5, the processor 5 is controlled by the host module and sends control commands to the drive module through a communication interface.

[0055] In this embodiment, in one example, the transmission mechanism 4 includes a key for coaxially connecting the motor shaft and the rotating shaft 2. The drive motor 8 is controlled by the host module to rotate forward or reverse, correspondingly causing the button cover 1 to rotate forward to expose the button hole 7 or to rotate backward to cover the button hole 7. When the button protection mechanism includes a processor, the host module controls the drive motor 8 through the processor. In one example, when the host module detects the left platform by combining the first arrival sensor and the voice recognition result, the host module sends an opening command to the processor of the button protection mechanism surrounding the release left door button. The processor controls the drive motor to rotate forward, causing the button cover 1 to rotate forward to expose the release left door button in the button hole 7.

[0056] In a preferred embodiment of this invention, such as Figure 7 As shown, the transmission mechanism 4 includes a worm gear structure and at least one cascaded gear transmission pair; when the gear transmission pair has multiple stages, the multi-stage gear transmission pairs are cascaded for transmission. The worm gear structure includes a worm coaxially connected to the motor shaft and a worm gear meshing with the worm. The worm gear is coaxially mounted with the input gear of the first-stage gear transmission pair, and the output gear of the last-stage gear transmission pair is sleeved on the outside of the rotating shaft 2. The worm gear converts the rotation of the motor shaft of the drive motor into the rotation of the worm gear, and then the rotation of the worm gear is transmitted to the rotating shaft 2 by at least one cascaded gear transmission pair, which drives the rotating shaft 2 to rotate, thereby realizing the up-and-down flipping of the button cover 1.

[0057] In another preferred embodiment, the transmission mechanism 4 includes a worm gear structure, at least one stage of gear transmission, and a magnetic drive pair. The worm gear structure includes a worm coaxially connected to the motor shaft and a turbine meshing with the worm. The turbine is coaxially mounted with the input gear of the first stage gear transmission, and the output gear of the last stage gear transmission is coaxially mounted with the driving magnetic wheel of the magnetic drive pair. The passive magnetic wheel of the magnetic drive pair is sleeved outside the rotating shaft 2. In this embodiment, the worm gear converts the rotation of the motor shaft of the drive motor into the rotation of the turbine. Then, at least one cascaded gear transmission transmits the rotation of the turbine to the driving magnetic wheel, causing it to rotate. Under the action of magnetic force, the passive magnetic wheel also rotates, causing the rotating shaft 2 to rotate, thus realizing the up-and-down flipping of the button cover 1. The magnetic drive pair is preferably, but not limited to, a magnetic gear pair Harmonic Drive CSG-5A.

[0058] In another preferred embodiment of this invention, the transmission mechanism 4 includes a worm gear structure and a magnetic drive pair. The worm gear structure includes a worm coaxially connected to the motor shaft and a turbine meshing with the worm. The turbine is coaxially mounted with the driving magnetic wheel of the magnetic drive pair, and the driven magnetic wheel of the magnetic drive pair is sleeved outside the rotating shaft 2. In this embodiment, the worm gear converts the rotation of the motor shaft of the drive motor into the rotation of the turbine, which drives the driving magnetic wheel to rotate. Under the action of magnetic force, the driven magnetic wheel also rotates, driving the rotating shaft 2 to rotate, thereby realizing the up-and-down flipping of the button cover 1.

[0059] In a preferred embodiment, such as Figure 8 As shown, the button protection mechanism includes a cover structure surrounding the door control button and a drive module controlled by the host module; the cover structure includes a base 3 and a button cover 1 located on the base 3 and movably connected to the base 3. The base 3 has a button hole 7 for accommodating the door control button. The button cover 1 is rotatably connected to the base 3. The button cover 1 can be flipped to cover or expose the button hole 7. The drive module is used to lock or release the relative movement between the button cover 1 and the base 3.

[0060] In this embodiment, the button cover 1 is manually flipped forward to cover the button hole 7, similar to... Figure 5 Manually flip the button cover 1 in the reverse direction to open and expose the button hole 7, similar to... Figure 6 The button cover 1 and the base 3 can be rotatably connected by a hinge or a pivot.

[0061] In this embodiment, such as Figure 8 and Figure 9 As shown, the drive module includes a first lock body 11 located on the button cover 1, a second lock body 31 located on the base 3 that cooperates with the first lock body 11, and a lock control module controlled by the host module to control the connection state of the first lock body 11 and the second lock body 31.

[0062] In this embodiment, when the button protection mechanism has a processor, the lock control module communicates with the processor; when the button protection mechanism does not have a processor, the lock control module communicates with the host module. The first lock body 11 may be a cuboid or... Figure 8 The N-shaped lock shown can also be a cuboid or a similar shape. Figure 8 The two cuboids shown can be arranged as needed.

[0063] In a preferred embodiment, the locking module is an existing telescopic shaft motor, telescopic rotary motor, or telescopic reciprocating motor, whose motor shaft extends or retracts in the length direction during operation. For example... Figure 8 As shown, the first lock body 11 has a first lock hole 12, and the second lock body 31 has a second lock hole 32. When the button cover 1 covers the base 3, the first lock hole 12 and the second lock hole 32 can be aligned. At this time, the motor shaft of the lock control module passes through both the first lock hole 12 and the second lock hole 32, locking the relative movement between the button cover 1 and the base 3. Before the lock control module receives the opening command from the host module, the relative movement between the button cover 1 and the base 3 is locked, and the train operator cannot open the button cover 1. Only when the lock control module receives the opening command from the host module will the motor shaft of the lock control module retract and exit the first lock hole 12 and the second lock hole 32, releasing the connection between the button cover 1 and the first lock body 11 and the second lock body 31 in the base 3, allowing the train operator to open the button cover 1.

[0064] In a preferred embodiment, the lock control module includes an electromagnet mounted on the first lock body 11 / second lock body 31, an iron plate mounted on the second lock body 31 / first lock body 11, an electromagnet power supply circuit, and a switching element that controls the start or stop of the electromagnet power supply circuit, the switching element being controlled by the host module. Figure 9 As shown, when it is necessary to close button cover 1, the host module sends a closing command to control the switch unit to close, energizing the electromagnet to generate magnetic force that attracts the iron piece, thus firmly attaching the first lock body 11 and the second lock body 31 together, preventing the train operator from directly opening button cover 1. When it is necessary to open button cover 1, the host module sends an opening command to control the switch unit to open, de-energizing the electromagnet, eliminating the magnetic force, and preventing it from attracting the iron piece. This means the first lock body 11 and the second lock body 31 are not firmly attached together, allowing the train operator to easily open button cover 1.

[0065] In a preferred embodiment, the button protection mechanism includes a cover structure surrounding the door control button and a drive module controlled by the host module. The cover structure includes a base 3 and a button cover 1 movably connected to the base 3. The base 3 has a button hole 7 for accommodating the door control button. The button cover 1 is slidably connected to the base 3. The drive module is used to lock or release the relative movement between the button cover and the base, and to slide the button cover 1 to cover or expose the button hole 7. The button cover 1 has a covering position that completely covers the button hole 7 during its sliding stroke. The drive module includes a first lock body 11 located on the button cover 1, a second lock body 31 located on the base 3 that cooperates with the first lock body 11 when the button cover 1 is in the covering position, and a lock control module controlled by the host module to control the connection state of the first lock body 11 and the second lock body 31. 。

[0066] In this embodiment, the train operator manually slides the button cover 1 to expose or cover the button hole 7. Both the button cover 1 and the base 3 can be square, and they can be connected via a sliding groove. The housing and cover structure disclosed in Chinese Patent Publication No. CN221563048U can also be referenced, and will not be described in detail here. The sliding stroke of the button cover 1 includes a covering position that completely covers the button hole 7 and a display position that completely exposes the button hole 7. The structures of the first lock body 11, the second lock body 31, and the lock control module can all refer to the settings in the preferred embodiment described above, and will not be described in detail here. When the lock control module controls the first lock body 11 and the second lock body 31 to be securely connected (i.e., locked), the button cover 1 cannot be slid, and the train operator cannot operate the lower door control button. When the lock control module controls the first lock body 11 and the second lock body 31 not to be securely connected (i.e., released), the button cover 1 can be slid, and the train operator can operate the lower door control button.
