Detailed ways

The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments.

As shown in FIG. 1 , an elevator voice control device includes a proximity detection module 1 , a control module 2 , a voice module 3 , an information matching module 4 , a display module 6 , and a power supply module 7 .

The proximity detection module 1 is electrically connected to the control module 2 for detecting whether the user is approaching the proximity detection module 1 , and when it is detected that the user is approaching, a signal is sent to the control module 2 .

The proximity detection module 1 is installed at a position where it is easy to detect the user, such as one meter high on the inner side wall of the car.

The maximum detection distance of the proximity detection module 1 is 50-60 cm to ensure that the distance between the user and the voice module 3 is relatively short.

The proximity detection module 1 includes an infrared proximity sensor.

The voice module 3 is electrically connected with the control module 2 and the information matching module 4, collects user voice information, outputs it to the control module 2 and the information matching module 4, and is controlled by the control module 2, and performs voice prompts when starting or dormant;

The installation positions of the proximity detection module 1 and the voice module 3 are close to ensure that the user approaches the proximity detection module 1 and the voice module 3 at the same time.

The information matching module 4 is electrically connected with the control module 2 and the voice module 3 , and is used for matching the collected voice information with the command information in the voice command list, and outputting the matching result to the control module 2 .

In the voice command list, the voice information that has a corresponding relationship with the control command includes and only includes floor selection information, door opening information, door closing information, intercom information, alarm information and other control commands related to the elevator car, so as to improve the accuracy of voice recognition. to avoid misidentification.

The display module 6 is electrically connected to the control module 2, receives the signal from the control module 2, is used for prompting when the voice module 3 starts or sleeps, and displays the elevator running state, the current elevator floor, the selected floor, the elevator information such as running direction.

As the control center of the elevator voice control device, the control module 2 is electrically connected with the elevator control system 5, and the elevator control system 5 is used as the upper computer to receive the signal from the proximity detection module 1, start or close the voice module 3, and receive the information matching module 4. , determine the user command, and send the user control command to the elevator control system 5.

The power module 7 is used to supply power to the entire elevator voice control device.

When the proximity detection module 1 detects that the user is approaching, it sends a signal to the control module 2. The control module 2 starts the voice module 3. The voice module 3 collects the voice information sent by the user, and sends the voice information to the information matching module 4. The information matching module 4. Match the voice information with the command information in the voice command list, and send the matching result to the control module 2, which sends the command to the elevator control system 5.

The user wakes up the voice module 3 by approaching the proximity detection module 1 with his hand or body, which not only ensures that the user is closer to the voice recognition module, thereby bringing about a higher accuracy of voice recognition, and solves the cumbersome wake-up word method and improves the user experience.

As shown in Figure 2, the process of a kind of elevator voice control method is as follows:

The S21 proximity detection module continuously detects the trigger signal

The proximity detection module 1 is an infrared proximity sensor, and the maximum detection distance is 50-60 cm;

The infrared proximity sensor emits an infrared signal. When no one approaches the proximity detection module 1, the infrared proximity sensor cannot receive the reflected infrared signal; when someone approaches the proximity detection module 1 within a certain distance, the infrared proximity sensor receives the received signal. The infrared signal reflected by the human body means that the human body approaching signal is detected.

When the proximity detection module 1 detects that a person or a hand is approaching, that is, a trigger signal is detected, S22 is performed; when the proximity detection module 1 does not detect that a person or a hand is approaching, S23 is performed. Make sure that the voice module 3 is activated only when the user is close to the proximity detection module 1. Compared with the existing method of using wake words, it is easier to use; and because the user is closer to the voice module 3, the voice recognition accuracy will be greatly improved. .

S22 wake up voice module

The voice module 3 sends out a voice prompt, such as: "Welcome to take the elevator, please set the floor", and at the same time starts to detect and receive the user's voice information.

If the user's voice is not detected within a certain period of time, the voice recognition will be terminated;

If it is detected that the user's voice starts, it will be regarded as the end of the voice within a certain period of time after the user ends.

S23 voice module remains dormant

When the voice module 3 remains in a dormant state, it does not accept voice information, so as to avoid misrecognition of the voice signal, resulting in a decrease in the recognition accuracy.

S24 Voice Information Matching

The voice module 3 receives the voice information and matches the command information in the voice command list. When the matching is successful, S25 is executed; when the matching is unsuccessful, S22 is executed, and a voice prompt is issued to the user, such as "Unable to recognize, please you repeat".

In the voice command list, the voice information corresponding to the control command includes and only includes: floor selection information, door opening information, door closing information, intercom information, alarm information and other control commands related to the elevator car. Limiting the content of the voice command list can improve the voice recognition rate.

S25 determines the control instruction

Determine the control command according to the matching result of the command information of the voice module 3,

S26 Send control commands to the elevator control system

The control module 2 sends control instructions to the elevator control system.

The above method starts the voice module 3 by approaching the detection module 1 with the hand or the body, collects and recognizes the user's voice information, determines the user's instruction and sends the instruction to the elevator control system, and completes the identification and processing of the user's demand information, and does not need to be used. The wake word improves the accuracy of speech recognition and improves the user experience.

There may be many ways to implement the method and system of the present invention. For example, the methods and systems of the present invention may be implemented in software, hardware, firmware, or any combination of software, hardware, and firmware. The above-described order of the steps of the method is for illustration only, and the steps of the method of the present invention are not limited to the order specifically described above unless specifically stated otherwise. Furthermore, in some embodiments, the present invention can also be implemented as programs recorded in a recording medium, the programs comprising machine-readable instructions for implementing the methods according to the present invention. Thus, the present invention also covers a recording medium storing a program for executing the method according to the present invention.
