DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The following describes an elevator voice control device, an elevator voice control method and an elevator provided by embodiments of the present invention with reference to the accompanying drawings.

[0022] Figure 1 4 is a block diagram of an elevator voice control device according to an embodiment of the present invention.

[0023] like Figure 1 As shown, the elevator voice control device 100 according to the embodiment of the present invention may include: a voice acquisition module 110 , a voice recognition module 120 and a control module 130 .

[0024] The voice acquisition module 110 is used to acquire the elevator call command, which includes the target floor information. For example, the voice acquisition module 110 can be installed at the call position of each elevator. When a passenger arrives near the call position of a certain elevator (e.g., within 3 meters), and speaks the floor he wants to reach, that is, the target floor, the voice acquisition module 110 can collect the passenger's voice.

[0025] The speech recognition module 120 is connected to the speech acquisition module 110 , and is used to recognize the elevator call command and convert the recognized elevator call command into communication data, wherein the communication data includes target floor information and information about the floor from which the elevator call command is issued.

[0026] The control module 130 is connected to the voice recognition module 120 and the control system of the elevator respectively. The control module 130 is configured to parse the converted elevator call command to obtain the elevator call instruction, and send the elevator call instruction to the control system of the elevator, so that the control system of the elevator controls the elevator to run to the floor where the elevator call command is issued according to the elevator call instruction, and controls the elevator to run to the target floor.

[0027] Specifically, when the passenger arrives at the call position of the elevator on this floor, he / she speaks the floor he / she wants to reach. For example, the passenger speaks the voice "small elevator to the 4th floor", and the voice acquisition module 110 collects the elevator call command issued by the passenger and transmits the elevator call command to the voice recognition module 120. The voice recognition module 120 recognizes the received elevator call command, identifies the target floor and the floor where the passenger is located in the elevator call command, and then converts these contents into communication data and transmits them to the control module 130. After receiving the communication data, the control module 130 parses the communication data to obtain the elevator call command corresponding to the elevator call command. The control module 130 can be connected to the communication bus of the elevator through the communication interface to send the elevator call command to the control system of the elevator. The control system of the elevator first controls the elevator to run to the floor where the elevator call command is issued according to the elevator call command, and controls the elevator door to open. After the passenger enters the elevator, the control system of the elevator controls the elevator to run to the target floor according to the elevator call command. Therefore, the elevator voice control device 100 of the present invention can realize that the passenger speaks once outside the floor, the elevator arrives at the current floor to pick up the passenger, and directly reaches the target floor, which is convenient for passengers to take the elevator.

[0028] It should be noted that the voice recognition module 120 is an independent module, and its program file is generated by computer-side configuration software, wherein the configuration software has the function of converting input voice text into serial communication data, configures the input text and the corresponding output data and response voice, and then generates a program file, and burns the generated file into the voice recognition module 120 through the voice recognition module programming interface. Furthermore, when the device is used for the first time, the setting mode can be entered through voice commands to set the floor address of the device and set the address for the 1-N floor outbound calls.

[0029] According to an embodiment of the present invention, the speech recognition module 120 is further configured to perform speech self-learning upon receiving a preset self-learning command.

[0030] Specifically, the voice recognition module 120 has a self-learning function. When the user issues a preset self-learning command such as "set self-learning mode", the voice recognition module 120 performs voice self-learning. For example, the voice recognition module 120 can install a set standard language sequence, and the user repeats it twice in his own voice. The voice recognition module 120 completes the synchronous recognition of the standard voice and the learning voice, and outputs the relevant data to the voice recognition module 120 for storage. Therefore, through the voice self-learning function of the voice recognition module 120, it is convenient for some people who can only speak local dialects or have inaccurate pronunciation to use it, which can improve the user experience.

[0031] According to one embodiment of the present invention, Figure 2As shown, the elevator voice control device 100 also includes: a lighting module 140, which is connected to the control module 130. The control module 130 is used to control the lighting module 140 according to the working mode, and the working mode includes a night mode, an atmosphere mode and an automatic mode.

[0032] Specifically, the lighting module 140 can be set to a variety of working modes, including night mode: the lighting is automatically turned on only at night; atmosphere mode, the brightness is adjusted to 50% during the day and 100% at night; automatic mode, the lighting is turned on only when someone issues an elevator call command, and it turns off after a delay of 30 seconds. The control module 130 is used to control the lighting module 140 according to the working mode, control the brightness of the lighting module 140, turn it on or off, etc. In some embodiments, the lighting module 140 can be an LED light strip. For example, Figure 3 As shown, a lampshade is provided at the button of the external button touch panel, and the LED light strip can be installed in the lampshade, wherein the lampshade is transparent or translucent. Of course, the lighting module 140 can also be installed in other positions suitable for lighting, which is not limited here.

[0033] According to one embodiment of the present invention, Figure 2 As shown, the elevator voice control device 100 also includes: a brightness detection module 150, which is connected to the control module 130, and the brightness detection module 150 is used to obtain the brightness information of the floor where the elevator call command is issued; the control module 130 controls the lighting module 140 according to the brightness information.

[0034] Specifically, the brightness detection module 150 can detect the brightness of the floor where the elevator call command is issued, and send the obtained brightness information to the control module 130. The control module 130 compares the brightness information with the preset brightness threshold. When the brightness information is greater than or equal to the preset brightness threshold, the control module 130 controls the lighting module 140 not to work; when the brightness information is less than the preset brightness threshold, the control module 130 controls the lighting module 140 to work and perform lighting.

[0035] According to one embodiment of the present invention, Figure 2 As shown, the elevator voice control device 100 also includes: a detection module 160, which is connected to the control module 130. The detection module 160 is used to output a detection signal to the control module 130 when a passenger approaches the elevator; the control module 130 is used to control the lighting module 140 to perform lighting according to the detection signal and brightness information.

[0036] Specifically, when the brightness information is less than the preset brightness threshold, such as at night, the detection module 160 detects whether there are passengers approaching the elevator. When the passenger is about 3-5 meters away from the device, the detection module 160 detects that there are passengers approaching and outputs a detection signal to the control module 130. The control module 130 controls the lighting module 140 to illuminate and guide the passengers to the elevator door. When there are no passengers approaching the elevator, the detection module 160 does not output a detection signal, and the control module 130 controls the lighting module 140 not to work. This can prevent the lighting module 140 from being always on when the brightness is low, save power, and extend the service life of the lighting module 140.

[0037] According to one embodiment of the present invention, the elevator includes an external button touch panel and an internal button touch panel, and the control module 130 is connected to the external button touch panel and the internal button touch panel respectively. The control module 130 is also used to control the corresponding button answer light according to the elevator call instruction.

[0038] Specifically, when the passenger arrives at the call position of the elevator on this floor, he / she speaks the floor he / she wants to reach. For example, the passenger speaks the voice "small elevator to the 4th floor". The voice acquisition module 110 collects the elevator call command issued by the passenger and transmits the elevator call command to the voice recognition module 120. The voice recognition module 120 recognizes the received elevator call command, identifies the target floor and the floor where the passenger is located in the elevator call command, and then converts these contents into communication data and transmits them to the control module 130. After receiving the communication data, the control module 130 parses the communication data to obtain the elevator call command corresponding to the elevator call command. The control module 130 can be connected to the communication bus of the elevator through the communication interface to send the elevator call command to the control system of the elevator. After receiving the elevator call command, the control system of the elevator sends a response indication to the control module 130. When the control module 130 receives the response indication, it controls the answer light of the up call button or the down call button in the external button touch panel to light up according to the position relationship between the target floor and the current floor. The control system of the elevator first controls the elevator to run to the floor where the call command is issued according to the call instruction, cancels the answer indication, and controls the elevator door to open. At this time, the control module 130 controls the answer light of the previously lit up call button or down call button to go out. At the same time, the control module 130 sends a target floor instruction to the control system of the elevator, and controls the answer light of the button corresponding to the target floor in the internal button touch panel to light up. After the passengers enter the elevator, they can see that the answer light of the button corresponding to the target floor (4th floor) is on. The control system of the elevator then controls the elevator to run to the target floor according to the target floor instruction.

[0039] According to one embodiment of the present invention, Figure 2As shown, the elevator voice control device 100 also includes: a voice playing module 170, which is connected to the voice recognition module 120. The voice recognition module 120 is used to respond to the elevator call instruction according to the preset response voice, and the voice playing module 170 is used to play the preset response voice.

[0040] For example, when a passenger says "take the small elevator to the 4th floor", the voice acquisition module 110 collects the elevator call command issued by the passenger and transmits the elevator call command to the voice recognition module 120. The voice recognition module 120 recognizes the received elevator call command and sends a preset response voice (such as "OK") to the voice playback module 170. The voice playback module 170 plays the preset response voice (such as "OK") for the passenger to hear so that the passenger knows that the elevator call command issued by him has been successfully received.

[0041] According to an embodiment of the present invention, the voice acquisition module 110 is a microphone array, and the microphone array is composed of N MEMS microphones, where N>2.

[0042] Specifically, under the same conditions, the noise reduction effect of a single microphone is worse than that of dual microphones. In order to improve the spatial gain and signal-to-noise ratio of the picked-up signal, enhance the noise reduction function of speech recognition, and adapt to the noise environment of the elevator, the microphone array includes at least 4 microphones; at the same time, in order to maintain the consistency of the microphone parameters, this embodiment uses a high-sensitivity digital MEMS microphone.

[0043] In summary, according to the elevator voice control device of the embodiment of the present invention, the voice acquisition module acquires the elevator call command, the voice recognition module recognizes the elevator call command, and converts the recognized elevator call command into communication data, the control module parses the converted elevator call command to obtain the elevator call instruction, and sends the elevator call instruction to the elevator control system, so that the elevator control system controls the elevator to run to the floor where the elevator call command is issued according to the elevator call instruction, and controls the elevator to run to the target floor. Thus, the device can realize external call to call the elevator and internal selection of the designated floor through voice, without entering the elevator car to operate the elevator, and has low modification cost and high reliability.
