Description

Technical Field

[0001] This invention relates to the field of elevators, and more particularly to an elevator voice call device, detection system and detection method. Background Technology

[0002] Currently, with the maturity of voice-activated elevator technology, there is a demand to retrofit elevators that previously lacked voice-activated elevator systems. However, for aesthetic reasons, customers prefer that the voice-activated elevator device not disrupt the existing elevator design; that is, they want the device to be concealed within the existing control panel or landing call area, utilizing the existing sound output holes on the panel for voice pickup and feedback.

[0003] However, in the existing technology, the existing sound holes on the original panel are generally relatively small for aesthetic reasons. When the voice call device is installed in a hidden manner, it is difficult to align the sound pickup hole of the voice call module with the sound hole of the panel. As a result, the voice call device cannot achieve the best sound pickup working state after installation, which greatly affects the response speed and recognition rate of the voice call and reduces the user's voice call experience.

[0061] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0062] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0063] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0064] This invention provides a detection system for an elevator voice call device, which is applied to the elevator voice call device. The elevator voice call device includes a microphone 1, which is hidden and installed behind the control panel of the elevator equipment at an initial preset position.

[0065] Furthermore, the detection system includes:

[0066] Storage module 2 contains pre-set standard test data;

[0067] Acquisition module 3 is connected to microphone 1 and is used to acquire the external detection audio collected by microphone 1;

[0068] Processing module 4, connected to acquisition module 3, is used to process the detected audio to obtain processed data and output it.

[0069] The comparison module 5 is connected to the processing module 4 and the storage module 2 respectively. It is used to compare the processed data with the standard test data and output the comparison results.

[0070] The prompting module 6 is connected to the comparison module 5 and is used to prompt the installer with the corresponding test results based on the comparison results, so that the installer can adjust the installation position of the microphone 1.

[0071] Furthermore, the detection system also includes:

[0072] Startup module 7 is used to start the detection system and begin operation.

[0073] In one embodiment, the start module 7 is an externally located start button.

[0074] Specifically, the start button can be installed on the existing panel of the elevator control system. The installer presses the start button to activate the detection system to test the elevator call device.

[0075] In another embodiment, the startup module 7 is a remote startup tool connected to the detection system.

[0076] Furthermore, a start button can be installed in the remote start tool. Installers can start the detection system to test the elevator call device by pressing the start button on the remote start tool, thereby improving the flexibility of the detection system.

[0077] In another embodiment, the startup module 7 is a device for automatically starting the detection system via voice command.

[0078] Specifically, in this embodiment, the startup module 7 is configured with:

[0079] Storage unit 71, which has a preset standard startup voice;

[0080] The comparison unit 72 is connected to the storage unit 71 and is used to acquire the external speech collected by the microphone 1, compare it with the standard start speech, and output the comparison result.

[0081] The start unit 73 is connected to the comparison unit 72 and is used to start the detection system when the comparison result indicates that the voice collected by the microphone 1 matches the standard start voice.

[0082] Specifically, the speech acquired by microphone 1 can be a perfect match with the standard start speech, or it can be a wide match that allows for partial speech order reversal or intervals, and extends to synonyms, near-synonyms, and related words of the standard start speech.

[0083] Furthermore, installers can use simple commands such as "Start detection" or "Detection" to activate module 7 to automatically start the detection system and test the elevator's automatic call device.

[0084] Furthermore, the detection system sets up a detection sound source at a fixed external location to emit detection audio. The detection audio has preset and stable audio properties, and the standard test data is adjusted according to the preset audio properties.

[0085] Specifically, by using a test audio source that plays test audio with preset and stable audio properties, inconsistent test results caused by differences in the volume or accent of the testers can be avoided.

[0086] Specifically, the preferred location for setting the detection sound source is the location simulating a passenger calling the elevator, which better ensures consistency between the detection process and actual use. This fixed location can be set 0.5m directly in front of the voice call device at a height of 1.5m; or at one of the four corners of the elevator car at a height of 1.5m. Of course, the above locations can be adjusted appropriately according to actual circumstances.

[0087] Furthermore, processing module 4 specifically includes:

[0088] The filtering unit 41 is used to filter out valid speech from the detected audio and output the audio attributes of the valid speech as processing data.

[0089] Comparison module 5 specifically includes:

[0090] The first comparison unit 51 is used to compare the audio attributes of the valid speech with the standard test data and output the comparison results.

[0091] In one embodiment, standard test data includes the sound pressure level of speech.

[0092] Furthermore, the audio properties of effective speech include the sound pressure level of the effective speech.

[0093] Specifically, the sound pressure level (SPL) value can be a specific numerical value or a defined range. The matching process for the SPL value can be either simple numerical matching or range matching. If the actual SPL value is higher or lower than the preset standard SPL value, or if the actual SPL value is outside the preset standard SPL value range, the matching fails, meaning the microphone's installation position needs adjustment. Conversely, if the actual SPL value is within the preset standard range, the microphone's installation position does not need adjustment.

[0094] In another embodiment, standard test data includes the audio curve of the detected audio.

[0095] Furthermore, the audio properties of effective speech include the audio curve of effective speech.

[0096] Furthermore, the comparison result represents the degree of matching between the audio curve of the valid speech and the audio curve of the speech in the standard test data. Therefore, the matching process for the audio curve can be considered as matching the curve shape. For example, if the actual audio curve perfectly matches the standard audio curve or the matching degree is greater than a preset matching degree, it indicates that the microphone's installation position does not need adjustment. Conversely, it indicates that the microphone's installation position needs adjustment.

[0097] In another embodiment, the standard test data may include both the sound pressure level and the audio curve of the speech, which can be selected according to preset settings:

[0098] One possible scenario is that both of the above matching processes must be satisfied simultaneously for the microphone installation position to not need adjustment; otherwise, the installation position needs adjustment.

[0099] Another setting can be expressed more loosely: if either of the above two matching processes is satisfied, it means that the microphone installation position does not need to be adjusted; only when neither is satisfied does it mean that the installation position needs to be adjusted.

[0100] In this embodiment, the matching process described above can be precise matching or fuzzy matching with a certain tolerable range. Furthermore, all matching and comparison processes in this technical solution can be precise matching or fuzzy matching, which will not be elaborated on further below.

[0101] The above embodiments describe the specific working principle of the detection system when the detected audio is a pure tone. The following embodiments describe how the detection system should work when the detected audio is detection speech with certain broadcast content:

[0102] In another embodiment, standard test data includes the recognition rate of detected audio.

[0103] Specifically, in this embodiment, the external detection audio is detection speech with preset broadcast content.

[0104] Furthermore, processing module 4 specifically includes:

[0105] The recognition unit 42 is used to recognize the detected speech and output the recognition result;

[0106] The detection unit 43 is connected to the recognition unit 42 and is used to detect the recognition result of the recognition unit 42 and output the detection result as processed data.

[0107] Comparison module 5 specifically includes:

[0108] The second comparison unit 52 is used to compare the detection results with the standard test data and output the comparison results.

[0109] The recognition rate can be a specific numerical value or a defined range of values. Therefore, the matching process based on the recognition rate can be simple numerical matching or range matching. If the recognition rate of the recognition unit 42 is higher or lower than the preset recognition rate of the detected speech, or if the recognition rate of the recognition unit 42 is not within the preset range of the detected speech recognition rate, then the matching fails, meaning the microphone's installation position needs to be adjusted. Conversely, if the recognition rate is lower than the preset range, then the microphone's installation position does not need to be adjusted.

[0110] In another embodiment, the standard test data includes the standard response time.

[0111] Specifically, in this embodiment, the acquisition module 3 includes:

[0112] The recording unit 31 is used to perform speech endpoint detection on the detected speech and record the detected speech after the speech endpoint detection is completed.

[0113] The timing unit 32 is used to time the start time of the detection speech collected by the microphone 1 to the end time of the recording unit 31 completing the recording, and to record the timing result as the actual response time of the detection speech.

[0114] After the recognition result output by the recognition unit 42 indicates that the speech recognition is correct, the processing module 4 outputs the actual response time as the processing data.

[0115] Comparison module 5 specifically includes:

[0116] The third comparison unit 53 is used to compare the actual response time with the standard response time in the standard test data and output the comparison result.

[0117] The standard response time can be either a specific numerical value or a defined range. Therefore, the matching process for response time can be either simple numerical matching or range matching. If the actual response time is higher or lower than the standard response time, or if the actual response time is outside the preset standard response time range, the matching fails, indicating that the microphone's installation position needs adjustment. Conversely, if the actual response time is within the standard response time range, the microphone's installation position does not need adjustment.

[0118] Furthermore, the detected audio content included elevator instructions used during normal elevator use.

[0119] Specifically, the test voice uses the elevator instructions used when riding an elevator normally as the standard voice test command, so that the test command is consistent with the actual usage conditions.

[0120] In one embodiment, the prompting module 6 is a prompting device capable of providing feedback on the prompting screen and is pre-set with displacement offsets and directions corresponding to each situation of the comparison results, as well as colors corresponding to each displacement offset, and finally displays the screen of the offset that needs to be adjusted by varying the color intensity.

[0121] In another embodiment, the prompting module 6 is a prompting device capable of providing voice prompts, and is pre-set with displacement offsets and directions corresponding to each situation of the comparison results, as well as voice prompt content corresponding to each displacement offset and direction.

[0122] Specifically, the voice prompts use simple commands, such as "Up 3" and "Down 3".

[0123] Specifically, the installers adjusted the position of microphone 1 according to the voice prompts.

[0124] In another embodiment, the prompting module 6 is a prompting device capable of providing prompting visuals and voice prompts. It is pre-set with displacement offsets and directions corresponding to each situation of the comparison results, as well as colors corresponding to each displacement offset and voice prompt content corresponding to each displacement offset and direction.

[0125] Specifically, the prompt module 6 displays the offset amount that needs to be adjusted on the screen by using different shades of color, and at the same time broadcasts the voice prompt content.

[0126] Furthermore, the detection results fed back by the prompt module 6 include quantitative instructions for installers to adjust the installation position.

[0127] Specifically, the displacement offset corresponding to each case of the comparison results is calculated using multiple preset formulas. For example, if the sound pressure value of the detected audio is higher than the sound pressure value, the sound pressure value in the detected audio that is higher than the sound pressure value is converted into the number of standard units that need to be moved using a preset formula.

[0128] Specifically, the direction of the displacement offset corresponding to each case of the comparison results is determined by multiple preset formulas. For example, the direction of the displacement offset is opposite when the sound pressure value of the detected audio is higher than the sound pressure value and when the sound pressure value of the detected audio is lower than the sound pressure value.

[0129] Specifically, the prompt will be a voice indicating the direction and standard unit distance that microphone 1 should be adjusted to, or...

[0130] The image displays the offset that needs adjustment using varying shades of color, or

[0131] The system broadcasts the direction and standard unit distance of the microphone 1 to be adjusted, and displays the offset amount to be adjusted using color variations.

[0132] In another embodiment, the prompting module 6 is a debugging tool that is remotely connected to the detection system.

[0133] Specifically, the debugging tool can be computer software or mobile APP program installed on the installer's mobile terminal.

[0134] This technical solution also provides a method for monitoring elevator voice call functionality, to ensure that the voice call device can accurately and quickly acquire the user's voice call command while maintaining response speed and recognition rate. The elevator voice call detection method specifically includes the following steps:

[0135] Step S1: Input a detection audio through an external sound source, and use the acquisition module 3 to acquire the detection audio collected by the microphone 1;

[0136] Step S2: The detected audio is processed by processing module 4 to obtain processed data and then output.

[0137] Step S3: The comparison module 5 is used to compare the processed data with the standard test data and output the comparison results.

[0138] In step S4, the prompting module 6 prompts the installer with the corresponding test results based on the comparison results, so that the installer can adjust the installation position of the microphone 1.

[0139] The present invention also provides an elevator voice call device, which uses an elevator voice call detection system to adjust the installation position of the microphone 1 in the elevator voice call device.

[0140] The present invention also provides an elevator voice call device, which uses an elevator voice call detection method to adjust the installation position of the microphone 1 in the elevator voice call device.

[0141] The beneficial effects of the technical solution of the present invention are as follows: This technical solution utilizes the sound outlet on the original elevator control system panel, without damaging the original decoration appearance, making the effect after installation more aesthetically pleasing; and it can be started by voice command or through wireless connection debugging tools, avoiding problems such as inaccurate test results caused by disassembling and assembling the control box; the test results of this technical solution are quantitatively fed back by screen or voice, which is more intuitive and clear, enabling installers to quickly adjust the voice call device to the correct position.
