In the embodiment of the invention, the control chip MCU is used for switching the wireless communication protocol used by the wireless communication module WIFI & BT and controlling the serial port communication module UART to transmit data.

It should be noted that, the MCU (Micro Control Unit) is a microcomputer that appropriately reduces the frequency and specification of a Central Processing Unit (CPU), and integrates peripheral interfaces such as a Memory (Memory), a counter (Timer), a USB, an a/D conversion, a UART, a PLC (Programmable Logic Controller), a DMA (Direct Memory Access), and even an LCD (Liquid Crystal Display) driving circuit on a single chip to form a chip-level computer, which can be used for different applications, such as mobile phone, PC periphery, remote Controller, automotive electronics, industrial stepping motor, and Control of machine arms, and can also be used for the personal image of the MCU.

According to the embodiment of the invention, the wireless communication protocol used by the wireless communication module WIFI & BT can be switched through the control chip MCU, and the UART can also be controlled to transmit data, so that wireless network communication used by electrical equipment and transmitted communication data can be controlled.

In an optional embodiment of the present invention, the method may further include: a sound collection module MIC (Microphone) and a sound output module AMP (Amplifier); the sound acquisition module MIC is used for acquiring a voice signal of a user; the sound output module AMP is used for outputting audio data aiming at the speech signal.

It should be noted that ASR (Automatic Speech Recognition) is a technology for converting human Speech into text, and aims to allow a computer to "listen and write" continuous Speech spoken by different people, that is, a commonly called "Speech dictation machine", and is a technology for realizing conversion from "voice" to "text". Automatic Speech Recognition is also known as Speech Recognition (Speech Recognition) or Computer Speech Recognition (Computer Speech Recognition).

It should be noted that NLU (Natural Language Understanding) is a generic term of all method models or tasks that support machine Understanding of text content. The NLU plays a very important role in a text information processing system, and is an essential module of a system for recommendation, question answering, search and the like.
