Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of motor train unit, especially to a motor train unit device for preventing door opening error. BACKGROUND

[0002] A plurality of door control buttons, such as a left door release button, a left door opening button, a left door closing button, a right door release button, a right door opening button, and a right door closing button, are arranged on the operation table of the cockpit of the motor train unit. To prevent accidental touch of the door control buttons, a button protection shell is arranged on the outer cover of the door control buttons, and the shape of the button protection shell is matched with the door control buttons. Figure 3 A button protection shell is disclosed, which comprises a lower shell and an upper shell rotatably connected with the lower shell. The lower shell is arranged on the periphery of the door control buttons and has a button hole for accommodating the door control buttons.

[0003] After the motor train unit arrives at the station, the train attendant manually judges whether the platform is located on the left side or the right side of the motor train unit, and manually flips the upper shell of the button protection shell corresponding to the door control button of the left door or the right door according to the judgment result, exposes the button hole and the door control button in the button hole, and performs key operation to control the left door or the right door to open for passenger passage. Since the train attendant manually judges the door opening direction, sometimes the door may be opened in the wrong direction, which may cause important safety hazards to passengers. In the prior art, a motor train unit door opening and closing reminding device is disclosed in Chinese Patent No. CN221563048U. After the voice recognition module recognizes the left door opening or right door opening information played by the broadcast voice, the indication module of the corresponding door control button is controlled to display to prompt the train attendant to operate, which can to some extent avoid the train attendant's misoperation. However, when the environment inside the motor train is noisy, the voice recognition cannot accurately recognize the left door opening or right door opening information, which may cause the indication module to have the possibility of incorrect indication. At the same time, the patent only indicates the train attendant through the indication module, and cannot prevent the train attendant from opening the shell to operate the button. When the train attendant neglects the indication information of the indication module due to distraction or tension, there is still a possibility of incorrect operation of the door control button.

[0004] Therefore, there is no effective and reliable anti-misoperation and door opening error device for the door control button with the button protection shell in the prior art. UTILITY MODEL CONTENTS

[0036] In the description of the present application, unless otherwise specified and limited, it should be noted that the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be a mechanical connection or an electrical connection, or a communication between two elements, or a direct connection, or an indirect connection through an intermediate medium, and the specific meaning of the above terms can be understood by those skilled in the art according to the specific circumstances.

[0037] The utility model discloses a kind of EMUs prevent device of door misalignment, such as Figure 1 、 Figure 2 andFigure 4 As shown, comprising:

[0038] At least one base 2 is arranged at the periphery of the at least one button protection shell 1, each button protection shell 1 covers the periphery of a door control button; the base 2 is provided with a brake and a brake control mechanism, the brake is used to limit the overturning of the upper shell 11 of the button protection shell 1, and the brake control mechanism is used to control the movement of the brake;

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

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

[0041] A sound receiver is arranged to receive the sound signal in the EMU;

[0042] A host module, the first signal input end of the host module is connected with the output end of the first arrival sensor, the second signal input end of the host module is connected with the output end of the second arrival sensor, the third signal input end of the host module is connected with the output end of the sound receiver, and the control signal output end of the host module is connected with the control signal input end of the brake control mechanism. The host module is used to issue a control instruction to the brake control mechanism.

[0043] In the embodiment, the number of bases 2 and the number of brakes and brake control mechanisms on the bases 2 can be configured according to the number of button protection shells 1 arranged on the operation table of the EMU cockpit. The door control buttons generally include six buttons, i.e., a left door release button, a left door opening button, a left door closing button, a right door release button, a right door opening button, and a right door closing button. When the left / right door needs to be opened, the left / right door release button needs to be operated first to release the left / right door, and then the left / right door opening button can be operated. Therefore, only two bases 2 can be configured, and the two bases 2 are arranged on the operation table of the cockpit and close to the button protection shells 1 of the left door release button and the right door release button, respectively. More than two bases 2 can also be configured, for example, one base 2 is arranged at the periphery of each of the six button protection shells of the door control buttons.

[0044] In the embodiment, the base 2 is preferably but not limited to rectangular, square, strip-shaped, concave and other shapes, which can be connected on the cockpit console by bonding or screw fixing. In an example, a mounting table can be provided on the base 2, and the mounting table mounts a brake control mechanism. The brake can be a telescopic rod, and the linear motion path of the telescopic rod can be parallel to the plane where the upper shell 11 is located or slightly inclined. The brake control mechanism includes a linear motor 4 that controls the extension or shortening of the telescopic rod, and the telescopic rod is coaxially connected with the motor shaft of the linear motor 4. When no opening instruction of the host module is received, the upper shell 11 of the button protection shell 1 needs to be limited to flip back, and the linear motor 4 rotates forward to drive the telescopic rod to extend into the rotation stroke range of the upper shell 11. At this time, the telescopic rod is located above the upper shell 11, preventing the upper shell 11 from flipping back. When the opening instruction of the host module is received, the linear motor 4 reverses to drive the telescopic rod to exit the rotation stroke range of the upper shell 11, and is no longer located above the upper shell 11. At this time, the upper shell 11 can be successfully flipped back to expose the door control button covered by the button protection shell 1.

[0045] In the embodiment, the first and second arrival station sensors are preferably but not limited to installed on the windows on the side of the train set and the lower part of the train body close to the wheels. Since the height of the platform is greater than the height of the train track, in order to accurately obtain the arrival station signal, the first and / or second arrival station sensors are preferably distance sensors for measuring the distance between the train body and the objects on both sides of the train body. Therefore, the first and second arrival station sensors are preferably but not limited to existing millimeter wave radar sensors or ultrasonic radar sensors or laser distance sensors or ultrasonic distance sensors. The first and second arrival station 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 set enters the station, the light signals are reflected to the light receiving unit on the side of the platform. When the train set does not enter the station, the light receiving unit cannot receive the light signals, so as to identify whether the train set has arrived at the station and whether the platform is on the left side or the right side. The first and second arrival station sensors can be installed only on the train head, or multiple sensors can be installed on the train head, the train tail and the middle part of the train, respectively. The first and second arrival station sensors are preferably but not limited to suction cup suction connection or bonding or welding on the train set.

[0046] In the embodiment, as Figure 5As shown, the first and second arrival station sensors can also be platform cameras located on the left and right sides of the vehicle head, or behavior recognition cameras located in the driver's cabin. The host module can identify the platform name and platform building based on the platform camera image collection according to the existing target recognition algorithm, so as to obtain the information that the platform is located on the left side or the right side. The host module can also identify the train attendant's action based on the behavior recognition camera image collection according to the existing action recognition algorithm, to obtain the information that the platform is located on the left side or the right side. It should be noted that the above image processing algorithm is prior art and is not within the protection scope of the present application.

[0047] In the present embodiment, the sound receiver is preferably but not limited to a pickup or microphone, which is used to convert the sound signal into an electrical signal or a digital signal. The sound receiver can be installed in the vehicle cabin to collect the broadcast voice signal or can be installed in the driver's cabin to collect the voice command of the train attendant.

[0048] In the present embodiment, as shown, Figure 5 The host module can include a main controller, which is a microprocessor, preferably but not limited to AX650N of Aixometech. The main controller has a data storage unit inside, which can load existing voice recognition programs and image recognition programs, and can identify the train attendant's action through the image recognition program. The main controller can be connected to the output end of the first arrival station sensor, the output end of the second arrival station sensor, and the output end of the sound receiver through A / D pins or a data interface (such as UART serial port). The main controller compares the output signals of the first and second arrival station sensors with the preset signal threshold (corresponding to a distance threshold), and obtains the preliminary result of the left or right platform according to the comparison result. The main controller identifies the keywords "left platform" or "right platform" from the sound signal received by the sound receiver using the existing voice recognition program, and when the preliminary result is consistent with the keywords, the main controller sends a control instruction to the brake control mechanism corresponding to the button protection shell 1 of the key corresponding door control button through the RS485 communication interface or the wireless communication interface, so as to control the brake member to exit the stroke range of the upper shell 11. If the two are not consistent, the main controller does not send any instruction, and the brake control mechanism controls the brake member to extend into the stroke range of the upper shell 11. It should be noted that in the processing process of the above-mentioned main controller, whether the preliminary result is consistent with the keywords can be determined by using the AND operation principle, which is a conventional processing means in the art. For example, Chinese patents CN101673940A and CN109060080A both involve a technical solution of performing AND operation on two signals to obtain a new signal. Therefore, the method involved in the processing process of the main controller is a conventional processing means in the art, and is not within the protection scope of the present application.

[0049] In the embodiment, the functions of the host module can also be implemented by hardware, specifically, as shown in Figure 6 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 end of the first arrival sensor is connected with the positive input end of the first comparator, the output end of the reference power supply is connected with the negative input end of the first comparator, the output end of the first comparator is connected with the first input end of the first AND gate unit, the left platform detection end of the voice recognition module is connected with the second input end of the first AND gate unit, and the output end of the first AND gate unit is connected with the first detection end of the main controller. The output end of the second arrival sensor is connected with the positive input end of the second comparator, the output end of the reference power supply is connected with the negative input end of the second comparator, the output end of the second comparator is connected with the first input end of the second AND gate unit, the right platform detection end of the voice recognition module is connected with the second input end of the second AND gate unit, the output end of the second AND gate unit is connected with the second detection end of the main controller, and the main controller sends control instructions to each brake control mechanism. The models of the first comparator and the second comparator are preferably but not limited to LM324 and LM358, and the models of the first AND gate unit and the second AND gate unit are preferably but not limited to 74LS08 and 74HC08.

[0050] Figure 3In the embodiment, the voice recognition module can be a microprocessor loaded with an existing voice recognition program, which processes the sound signal output by the sound receiver, recognizes the keywords "left platform" or "right platform", and uses the high and low levels of the two I / O interfaces to represent whether the keywords "left platform" and "right platform" are detected. When the keyword "left platform" is detected, the left platform detection end of the voice recognition module (one I / O interface) outputs a high level, and the right platform detection end of the voice recognition module (the other I / O interface) outputs a low level. When the keyword "right platform" is detected, the right platform detection end of the voice recognition module outputs a high level, and the left platform detection end of the voice recognition module outputs a low level. The reference power supply is a power supply circuit outputting a reference voltage, which can be 0V or adjusted according to experience, and is used to determine whether the output signals of the two arrival sensors are arrival signals or non-arrival signals. If it is the left platform, the output signal of the first arrival sensor is greater than the reference power supply signal, and the first comparator outputs a high level. At this time, the second comparator outputs a low level. If the voice recognition module recognizes "left platform", the left platform detection end of the voice recognition module outputs a high level, the first AND gate unit outputs a high level, and the main controller sends a control instruction to the brake control mechanism on the base 2 corresponding to the left door control button. If the voice recognition module does not recognize "left platform", the left platform detection end of the voice recognition module outputs a low level, the first AND gate unit outputs a low level, and the main controller does not send a control instruction to the brake control mechanism on the base 2 corresponding to the left door control button. The button protection process of the right door can refer to the above description and will not be described here. It should be noted that the method of the main controller sending a control instruction to the corresponding brake control mechanism according to the detection signal is existing, such as the Chinese patent with publication number CN221563048U controlling the indication module of the corresponding shell to act according to the voice recognition result, which is not within the protection scope of the utility model.

[0051] In a preferred embodiment, the host module is connected in communication with the brake control mechanism through a communication interface. The communication interface can be a wired interface or a wireless interface, and the brake control mechanism is correspondingly provided with a wired interface and a wireless interface. 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 WIFI module, a 4G module and a 5G module, all of which are provided with an antenna.

[0052] In a preferred embodiment, as shown in Figure 7 The brake control mechanism includes a processor, which can be a microprocessor such as a single-chip microcomputer. As shown in Figure 4As shown, the processor is provided with a communication interface, through which the processor is connected in communication with the host module. The communication interface can be a wired interface or a wireless interface. Figure 7 As shown, the indication module is preferably but not limited to an indication light provided on the base 2, which can be a green light or a red light.

[0053] In a preferred embodiment, as shown in Figure 1 and Figure 2 The brake member is a brake cover 3 rotationally connected to the base 2, which is located above the upper housing 11, and the rotation stroke of the brake cover 3 overlaps the rotation stroke of the upper housing 11. The brake cover 3 can be semicircular or arc-shaped or rectangular or other special shapes. Figure 1 and Figure 2 As shown in the top view, the brake cover 3 can cover part or all of the upper housing 11, when covering all, the rotation stroke of the brake cover 3 completely overlaps the rotation stroke of the upper housing 11, and when covering part, the rotation stroke of the brake cover 3 partially overlaps the rotation stroke of the upper housing 11.

[0054] In this embodiment, preferably, the brake control mechanism includes a linear motor 4 and a telescopic shaft 5 that moves linearly under the drive of the linear motor 4, and the telescopic shaft 5 is controlled by the linear motor 4 to extend into or exit the rotation stroke of the brake cover 3. The telescopic shaft 5 can be the motor shaft of the linear motor 4, or a shaft coaxially connected to the motor shaft of the linear motor 4.

[0055] In one example of this embodiment, a mounting table can be provided on the base 2, on which the brake control mechanism is mounted, and the linear motion path of the telescopic shaft 5 can be parallel to the plane where the brake cover 3 is located, or slightly inclined to the plane where the brake cover 3 is located. When no host module opening instruction is received, the upper housing 11 of the button protection housing 1 needs to be restricted from being flipped backward, and the linear motor 4 is driven in the forward direction to drive the telescopic shaft 5 to extend into the rotation stroke range of the brake cover 3, and the telescopic shaft 5 is located above the upper housing 11 at this time, preventing the brake cover 3 and the upper housing 11 from being flipped backward. When the host module opening instruction is received, the linear motor 4 is driven in the reverse direction to drive the telescopic shaft 5 to exit the rotation stroke range of the brake cover 3, and is no longer located above the brake cover 3, at which time the brake cover 3 and the upper housing 11 can be successfully flipped backward to expose the vehicle door control button covered by the button protection housing 1.

[0056] In another example of this embodiment, as shown in Figure 1As shown, the brake control mechanism is installed at the bottom of the base 2. The linear motion of the telescopic shaft 5 interferes with the rotational stroke of the rear end of the brake cover 3 (i.e., the end of the brake cover 3 that is rotatably connected to the base 2). When the brake control mechanism does not receive the main module's opening command, it needs to restrict the upper housing 11 of the button protection housing 1 from flipping backward. The linear motor 4 rotates in the forward direction, driving the telescopic shaft 5 to extend into the rotational stroke range of the rear end of the brake cover 3, blocking the rotation of the rear end of the brake cover 3, thereby preventing the brake cover 3 and the upper housing 11 from flipping backward. When the main module's opening command is received, the linear motor 4 rotates in the reverse direction, driving the telescopic shaft 5 out of the rotational stroke range of the rear end of the brake cover 3, no longer blocking the rotation of the rear end of the brake cover 3. At this time, the brake cover 3 and the upper housing 11 can be successfully flipped backward, exposing the door control button covered by the button protection housing 1.

[0057] In a preferred embodiment, such as Figure 2 As shown, the base 2 has a concave surface 7 on its outer side to accommodate the button protective housing 1. In this case, the base 2 can be U-shaped. More preferably, to better accommodate the button protective housing 1 and save space, the concave surface 7 matches the shape of the button protective housing 1, such as... Figure 2 As shown, when the button protection housing 1 is cylindrical, the concave surface 7 is a concave arc surface that matches the cylindrical shape. The concave surface 7 can surround all or part of the outer surface of the button protection housing 1, such as... Figure 1 and 2 As shown, the concave surface 7 accommodates half of the outer surface of the button protective housing 1.

[0058] In a preferred embodiment, to simplify the installation, a fixing post 6 is provided at each end of the concave surface 7, and an elastic rope is connected between the two fixing posts 6. When the base 2 is secured to the outer periphery of the button protection housing 1 through the concave surface 7, the elastic rope is sleeved on the outer surface of the lower housing 12 of the button protection housing 1, and the elastic force of the elastic rope is used to fix the base 2. The elastic rope is preferably, but not limited to, a rubber band.
