Description

Intelligent voice recognition interphone

Technical Field

The utility model is applied to the technical field of elevator intercom devices, and particularly relates to an intelligent voice recognition interphone.

Background

Traditional elevator intercom only talkbacks the function, and the product is more single, and only floor function of arriving at a station takes the elevator and need press elevator button and floor, and the people that use have more, and the bacterium and the virus of contact also can increase, and is difficult to go to the operation floor button under the many crowded circumstances of people, and the peak period of being inconvenient for uses. With the update of the times, more and more intelligent products are produced at the present stage, and the matched intelligent equipment related to the elevator becomes a trend.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of overcoming the defects of the prior art and provides an intelligent voice recognition interphone capable of controlling the lifting floor through voice recognition and elevator control console communication.

The technical scheme adopted by the utility model is as follows: the intelligent interphone comprises a power supply voltage stabilizing module, an MCU module, a voice recognition module, an intercom module and a voice broadcasting module, wherein the power supply voltage stabilizing module is connected with an external direct-current power supply, the power supply voltage stabilizing module is in power supply connection with the MCU module, the voice recognition module, the intercom module and the voice broadcasting module are all in electric signal connection with the MCU module, the voice broadcasting module comprises a loudspeaker used for playing a voice signal fed back by the MCU module, the intercom module is connected with the loudspeaker, the intercom module and the voice recognition module are respectively provided with a first microphone and a second microphone, and the MCU module is communicated with an external control console.

According to the scheme, the voice command of the passenger is recognized through the second microphone of the voice recognition module and fed back to the MCU module, and then the MCU module is communicated with the control console of the elevator to select the stop floor. The talkback module is communicated with an external machine room switchboard through the MCU module to realize the traditional talkback function, so that the communication between the car and the machine room is realized. And the voice playing module receives the voice signal of the MCU module and converts the voice signal into an analog signal required by the loudspeaker, so that audio playing is realized. Meanwhile, the talkback module and the voice playing module share the loudspeaker, so that the equipment cost is reduced. And through with talkback the module with speech recognition module adopts two sets of microphones carries out speech recognition, and then guarantees not receive the interference of speech recognition function when needing the conversation of talkbacking, guarantees conversation quality, improves the security.

Preferably, the power supply voltage stabilizing module comprises a voltage reduction and stabilization chip with the model XL 1509.

Preferably, the MCU module comprises a processing chip with the model number STM32F103C8T 6.

Preferably, the voice recognition module comprises an intelligent voice chip with the model number of CI 1103.

Preferably, the voice broadcast module comprises an audio power amplifier chip with the model number of NS 4158.
