Description

Technical Field

[0001] The invention relates to an EMU door opening and closing reminder control device, belonging to the technical field of EMU safety control. Background Art

[0002] When the current EMU driver stops, the driver usually opens the left or right door by judging the content of the ATP door voice broadcast, and then the door corresponding to the passenger compartment will be opened (for example: the ATP broadcast announces "left platform", the driver presses the "open left door" button on the console, and the left door of the passenger compartment opens). Since the entire process is judged and executed by the driver himself, it is easy for the driver to mishear or misjudge and open the wrong door, posing a major hidden danger to the personal safety of passengers. Summary of the invention

[0003] The purpose of the present invention is to provide a motor vehicle door opening and closing reminder control device to avoid the problem of the motor vehicle driver opening the wrong door due to misjudgment of voice signals, thereby causing personnel safety problems.

[0004] In order to solve the above-mentioned technical problems, the present invention provides a EMU door opening and closing reminder control device, which includes a left door reminder control unit and a right door reminder control unit. The reminder control units on each side include a corresponding voice acquisition module, a voice recognition module and an indication module. The voice acquisition module is used to collect the voice broadcast signal in the train and send the collected signal to the voice recognition module. The voice recognition module is used to compare the received voice signal with the preset voice to obtain a recognition result, and control the corresponding indication module to act based on the recognition result; when the door reminder control unit on any side recognizes that the door on that side needs to be opened, the indication module on that side is controlled to act to indicate that the door control button on that side is enabled.

[0005] The present invention configures a corresponding door reminder control unit for each side door control button. The door reminder control unit uses a voice collection module to collect voice broadcast signals in the train, compares the collected voice signals with preset voices through a voice recognition module, obtains a recognition result, and controls the corresponding indication module action based on the recognition result. For example, when the voice recognition module of the left door reminder control unit recognizes the voice signal of "left platform", it indicates that the left door needs to be opened by operating the left door button. At this time, the voice recognition module of the left door reminder control unit controls the indication module on this side to indicate that the door control button on this side is enabled, so as to assist and remind the driver to correctly operate the corresponding button, avoid misjudgment leading to opening the wrong door, and thus improve the safety of personnel.

[0006] Furthermore, the door reminder control units on both sides are connected in communication to send their own voice recognition results to the other party's voice recognition module.

[0007] The present invention connects the door reminder control units on both sides for communication, and the voice recognition result on this side can be sent to the voice recognition module on the opposite side, so that when the door reminder control unit on either side cannot perform correct voice recognition due to a fault, the prompt module on that side can still be controlled, thereby improving the reliability of control.

[0008] Furthermore, the voice recognition module of each door reminder control unit is controlled according to its own voice recognition result and the received voice recognition result of the other party. When the recognition results of the two are consistent, control is performed according to the current recognition result, otherwise the indication module is not controlled.

[0009] In the present invention, the door reminder control unit on this side also combines the voice recognition result on the opposite side during control, and control is performed only when the recognition results on both sides are consistent. For example, when the left side is recognized as the left side, the right side is also recognized as the left side, which means that the recognition results on both sides are consistent, and corresponding control can be performed at this time. When the left side is recognized as the left side, and the right side is recognized as the right side, it means that the results on both sides are inconsistent. In order to avoid misidentification and give wrong indications, the indication modules on both sides are no longer controlled at this time.

[0010] Furthermore, the indicating module is an indicator light, and the indicator light includes at least two groups, one group is used to indicate that the door control button on this side is enabled, and the other group is used to indicate that the door control button on this side is disabled.

[0011] In order to further provide the driver with correct reminders, the present invention provides at least two groups of indicator lights, one group is used to indicate that the door control button on this side is enabled, and the other group is used to indicate that the door control button on this side is disabled. For example, when it is identified that it is the left side, the light group indicating that the left door control button is enabled can be controlled to operate, and at the same time, the light group indicating that the right door control button is disabled can be controlled to operate.

[0012] Furthermore, the voice recognition module controls the corresponding indication module action, which means controlling the action state of the indication module to last for a set time. After the set time is reached, the indication module returns to its original state.

[0013] Furthermore, the voice recognition module is also connected to a sensing module for obtaining a control instruction for the instruction module to restore to an original state. During the period when the voice recognition module controls the instruction module, if the voice recognition module senses the control instruction through the sensing module, the control instruction module restores to its original state.

[0014] In order to achieve more flexible control, the driver can interrupt the action of the indication module by operating the sensing module.

[0015] Furthermore, the power supply module of the reminder control unit on each side includes a battery, a boost circuit and an external DC / DC module. The boost circuit is used to stabilize the voltage of the battery to a set voltage. The input end of the external DC / DC module is connected to the output end of the boost circuit, and the output end of the external DC / DC module is powered and connected to the voice recognition module.

[0016] In order to provide a stable, reliable and required voltage for the reminder control unit, the present invention adopts a boost module and an external DC / DC module to perform voltage boost and voltage conversion.

[0017] Furthermore, each side reminder control unit is configured with a corresponding shell, the indication module is arranged on the surface of the shell, the voice collection module and the voice recognition module are both arranged inside the shell, and a cover for accommodating the door control buttons is arranged under the shell, and the cover is used to be placed in the area where the door control buttons are located on the corresponding side.

[0018] Furthermore, the voice recognition module is also connected to a power on / off circuit, a control button of the power on / off circuit is arranged on one side of the housing, and the voice recognition module is used to perform power on / off operations based on the state of the control button.

[0019] Furthermore, the speech recognition module is also connected to a charging circuit, and the charging circuit is used to charge the battery. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0038] The present invention configures a corresponding door reminder control unit for each side door control button. The door reminder control unit uses a voice collection module to collect voice broadcast signals in the train, and compares the collected voice signal with the preset voice through a voice recognition module to obtain a recognition result. Based on the recognition result, the corresponding indication module is controlled to act. When the door reminder control unit on any side recognizes that the door on that side needs to be opened, the indication module on that side is controlled to act to indicate that the door control button on that side is enabled, thereby assisting the driver in correctly operating the corresponding button to avoid opening the wrong door due to misjudgment, thereby improving the safety of personnel. The working principle of the EMU door opening and closing reminder control device is as follows: Figure 1 As shown, the detailed description is given below.

[0039] Each side reminder control unit includes a corresponding voice collection module, a voice recognition module and an indication module. The voice collection module is used to collect the voice broadcast signal in the train and send the collected signal to the voice recognition module. The voice recognition module is used to compare the received voice signal with the preset voice to obtain the recognition result, and control the corresponding indication module action based on the recognition result. When the door reminder control unit on any side recognizes that the door on that side needs to be opened, the indication module on that side is controlled to act to indicate that the door control button on this side is enabled. In order to reduce the misjudgment rate, the voice recognition module has added multiple judgments on the one hand, that is, the recognition is considered correct only when "left platform" or "right platform" is recognized more than 2 times.

[0040] In order to improve the reliability and accuracy of control, the reminder control units on both sides are connected in communication. In this embodiment, a low-power Bluetooth module is configured for the reminder control unit on each side. The voice recognition module in the reminder control unit on each side establishes communication with the voice recognition module in the reminder control unit on the opposite side through the respective Bluetooth modules, and the voice recognition modules on both sides can send the recognition results to the opposite side. In this way, when the door reminder control unit on any side cannot perform correct voice recognition due to a fault, the recognition result of the opposite side can still be obtained, and the voice recognition result of the opposite side is used to control the reminder module on this side, thereby improving the reliability of control. At the same time, the door reminder control unit on this side can also combine the voice recognition result of the opposite side when controlling, and control is only performed when the recognition results of both sides are consistent. For example, when the left side is identified as the left side, the right side is also identified as the left side, which indicates that the results of the recognition on both sides are consistent, and corresponding control can be performed at this time. When the left side is identified as the left side, and the right side is identified as the right side, it indicates that the results of the two sides are inconsistent. In order to avoid misidentification and give wrong instructions, the indication modules on both sides are no longer controlled at this time.

[0041] The indicating module in the present invention adopts an indicator light. The indicator light of the present invention is provided with at least two groups, one group is used to indicate that the door control button on this side is enabled, such as a flashing green light, and the other group is used to indicate that the door control button on this side is disabled, such as a constant red light. When it is identified that it is the left side, the left voice recognition module can control the flashing green light group on the left side to operate, and at the same time, the right voice recognition module will control the constant red light group on the right side to operate. The indicator light continues to operate according to the set time, and after the set time is reached, it returns to the original state. For example, when it is necessary to control the opening of the left door, the left voice recognition module controls the flashing green light on the left side for one minute, and after one minute, the green light stops flashing. In order to control the interruption of the indicator light at any time during its continuous operation, the present invention also provides a sensing module for sensing the driver's instruction to interrupt the continuous operation of the indicator light. Since the structure and control principle of the door reminder control unit are the same, the specific circuit used is also the same. The following is a detailed description of the specific circuit of the door reminder control unit on any side as an example.

[0042] like Figure 2 As shown, in this embodiment, the voice collection module adopts a MIC circuit, which adopts a differential structure, includes a microphone and a processing circuit, and can output two signals, MICP_L and MICN_L. These two signals are connected to the corresponding ports of the voice recognition module. When designing the PCB, the MIC circuit is routed away from other routes, and the MIC circuit is routed on the top layer without changing layers. When the train arrives at the station, the ATP system will broadcast which side of the platform the current train is parked on, and the voice played is "left platform" or "right platform". The above MIC circuit can be used to collect the voice signal played by the ATP system.

[0043] The speech recognition module in this embodiment is as follows Figure 3 As shown, the voice processing chip U1 (CI1303) is used. The voice processing chip is based on the RISC instruction set and integrates the brain neural network processor BNPU V3 and the CPU core. The voice processing chip processes the MICP_L and MICN_L signals output by the MIC circuit, compares them with the preset language module, and outputs the processing results. The AVDD, VDD33 and VDD11 pins of the chip are connected to external capacitors and installed close to the chip. PIN16 is an analog IO port and does not support 5V level. The remaining IO ports can be connected to 5V level.

[0044] The indicator module includes multiple light groups, such as Figure 4 As shown, there are red lights and green lights, and different display modes can be set as needed.

[0045] Power supply module such as Figure 5 and Figure 6 As shown, it includes a battery power supply circuit, a boost circuit and an external DC / DC circuit. The battery power supply circuit of the present invention adopts a 3.7V lithium battery. Since the output voltage of the lithium battery fluctuates and does not meet the 5V power supply requirement, it cannot be used directly. For this reason, the present invention adds a boost circuit, such as Figure 7The figure shows a boost chip (TPS61022RWUR), the input end of which is connected to a lithium battery through a switch circuit, and outputs a stable voltage of 5V for use by the system. On the one hand, it is connected to an external DC / DC circuit (1.1V step-down circuit), and on the other hand, it can directly power 5V devices. Since the voice processing chip of the present invention has both 5V and 1.1V requirements, the 5V requirement can be provided by the boost circuit, and the 1.1V requirement can be provided by the DC / DC module integrated inside the voice processing chip, or by the external DC / DC circuit of the present invention. Considering the power consumption of the voice processing chip, the present invention uses the 1.1V voltage output by the external DC / DC circuit to provide support for the voice processing chip. In order to charge the lithium battery, the present invention also provides a charging circuit, such as Figure 8 As shown, the charging circuit is implemented by using the MCP73831 chip, the VBAT pin of the chip is connected to the lithium battery, and the VDD pin is connected to the USB_VCC port, which is used as a charging port for connecting an external charging power source. In order to be able to charge in time, the present invention also monitors the battery power and sets a power indicator light. When the battery power is too low when the power is turned on, the power indicator light is controlled to light up.

[0046] In order to facilitate the on / off operation, the present invention also provides an on / off circuit, such as Fig. 9 As shown, there is a switch button SW1. When it is necessary to turn on the machine, press the button SW1, at this time Q3 is turned on, PA5 is locked in the high level state, even if the button SW1 bounces back, PA5 is still in the high level state, thereby realizing the power-on operation. When it is necessary to shut down the machine, press SW1 as well, the KEY_DET end is monitored by the voice chip as a low level state and lasts for more than 3s, and PA5 is controlled to be a low level, thereby realizing the shutdown.

[0047] The communication module uses a low-power Bluetooth module, such as Fig.10 As shown, a low-power Bluetooth chip is used, and the signal receiving pin and transmitting pin of the Bluetooth chip are connected to the voice processing chip. Since the working voltage of the Bluetooth chip is 3.3V, the present invention also sets a Bluetooth circuit, such as Fig.11 As shown, it is used to convert the 5V voltage output by the boost module into 3.3V to power the low-power Bluetooth chip.

[0048] In order to facilitate the upgrade of the voice recognition chip, an upgrade circuit is also provided, such as Fig.12 As shown, since the upgrade circuit provides a USB interface, the present invention also adds a USB interface circuit, such as Fig.13 shown.

[0049] The sensing module in this embodiment is a touch sensing disk, such as Fig.14As shown, it is set in the indicator light emitting area. The driver can cancel the action by lightly touching the module light emitting area during the indicator light action and restore it to the original state.

[0050] In order to facilitate installation, the present invention is provided with a housing, and the above circuits are installed in the housing, and in order to facilitate display and control, such as Fig.15a As shown, each light group is arranged on the upper surface of the shell, the power indicator light 4 is also arranged on the surface of the shell, the power button 3 is also arranged outside the shell, and the touch sensor plate is arranged in the light-emitting area of ​​the indication module, that is, also on the upper surface of the shell. At the same time, for the convenience of wiring, the Bluetooth interface, the charging port 2, etc. are all arranged on the shell. In order to facilitate the reception of sound, the microphone hole 1 is also arranged on the surface of the shell; at the same time, in order to facilitate installation in the area where the door control button is located, a cover for accommodating the door control button is assembled under the shell, and the cover is used to be installed in the area where the door control button is located on the corresponding side, such as Fig.15b As shown, in order to prevent the cover from leaving the area where the door control buttons are located due to fluctuations during vehicle operation, the present invention also installs an anti-skid rubber pad 5 on the side wall at the bottom of the cover. When the door control buttons are not operated, the cover (including its upper shell) is installed above the area where the door control buttons are located. When the door control buttons need to be operated, the cover can be directly removed.
