s21 proximity detection module continuously detects trigger signal
The approach detection module 1 is an infrared approach sensor, and the maximum detection distance is 50-60 cm;
the infrared proximity sensor transmits an infrared signal, and when no person approaches the proximity detection module 1, the infrared proximity sensor cannot receive the reflected infrared signal; when a person approaches the proximity detection module 1 within a certain distance, the infrared proximity sensor receives an infrared signal reflected by the human body, that is, a human body approach signal is detected.
When the approach detection module 1 detects a person or a hand approaching, that is, detects a trigger signal, S22 is executed; when the proximity detection module 1 does not detect a person or a hand approaching, S23 is performed. The voice module 3 is started only when the user approaches the approach detection module 1, and compared with the existing mode of using the awakening words, the voice module is simpler to use; and because the user is closer to the voice module 3, the voice recognition accuracy rate can be greatly improved.
S22 awakening voice module
The voice module 3 sends out voice prompts, such as: the method comprises the steps of 'welcoming to get on a ladder and please set a floor', and simultaneously starting to detect and receive voice information of a user.
If the user voice is not detected within a certain time, stopping voice recognition;
and if the voice start of the user is detected, the voice end is regarded within a certain time after the user ends.
S23 Voice Module remaining dormant
When the voice module 3 is kept in the dormant state, the voice information is not accepted, so that the error recognition of the voice signal is avoided, and the recognition accuracy is reduced.
S24 matching of voice information
The voice module 3 receives the voice information and matches the voice information with the instruction information in the voice instruction list, and if the matching is successful, S25 is executed; when the matching is unsuccessful, S22 is executed, and a voice prompt such as "not recognized, please repeat" is issued to the user.
In the voice instruction list, the voice information corresponding to the control instruction includes and only includes: floor selection information, door opening information, door closing information, talkback information, alarm information and other control instructions related to the elevator car. The limitation of the content of the voice command list can improve the voice recognition rate.
