[0033] like Figure 1As shown, a smart living cabin voice assistant system for RVs includes a Baidu AI device, a Wi-Fi voice controller, a gateway control panel, a Bluetooth amplifier, a vehicle-mounted Wi-Fi router, and an AI semantic cloud platform server. The Wi-Fi voice controller is connected to the AI ​​semantic cloud platform server via the vehicle-mounted Wi-Fi router, and the Wi-Fi voice controller and the AI ​​semantic cloud platform server interact with the Wi-Fi voice controller through the vehicle-mounted Wi-Fi router. The output of the Wi-Fi voice controller is connected to the voice alarm interface of the Baidu AI device, the gateway control panel, and the Living CAN bus of the Bluetooth amplifier. The AI ​​semantic cloud platform server is connected to the Baidu Cloud server through a cloud-to-cloud connection service. The AI ​​semantic cloud platform server is connected to the Baidu AI device through the Baidu Cloud server. The Baidu AI device is connected to the audio interface of the Bluetooth amplifier. The TV audio interface of the Bluetooth amplifier can be connected to a TV, and the Bluetooth amplifier's audio Bluetooth can communicate with a mobile phone. The connection relationship of the Bluetooth amplifier is as follows. Figure 12 and Figure 15 As shown.

[0034] In addition, the AI ​​semantic cloud platform server is connected to the vehicle's Wi-Fi router via a 4G network. The vehicle's Wi-Fi router is connected to the AI ​​semantic cloud platform server, the Baidu cloud server, and the Wi-Fi voice controller. The Wi-Fi voice controller is connected to the CCM module via a CAN bus. The CCM module is connected to devices installed in the RV's living compartment, including the refrigerator, water tank, heating system, water pump, entertainment system, auxiliary headlights, reading lights, air conditioner, outdoor lights, general lighting, and ambient lighting (see...). Figure 3 ).

[0035] like Figures 4 to 8 and Figure 11 As shown, the WIFI voice controller is a dedicated data communication module for RVs, including a housing, a PCB board inside the housing, and components mounted on the PCB board. Its electrical schematic diagram is shown below. Figure 9 and Figure 10 As shown, the electrical working principle is as follows: An external power supply of 9~16V is input, which is converted into 5V and 3.3V by the power conversion chip LM317AG-TN3-R. The 5V is used to power the CANBUS transceiver chip TJA1042T / 3, and the 3.3V is used to power the chip ESP32-S3-WROOM-1U.

[0036] The user triggers through the gateway control panel, enabling the ESP32-S3-WROOM-1U chip in the WIFI voice controller to control two status indicator lights to provide the user with the network configuration status message. And the ESP32-S3-WROOM-1U chip interacts with Xiaodu voice through the antenna, and then converts the control instructions provided by the Xiaodu AI device into CANBUS through the CANBUS transceiver chip TJA1042T / 3 to control external devices. The WIFI voice controller uploads the front-end voice signal collection to the AI semantic cloud platform server for parsing and then issues it locally. The WIFI voice controller receives it and issues it to the functional devices used in the vehicle terminal and executes the relevant devices and linkage scenarios; the WIFI voice controller adopts a closed-loop link architecture of "local collection-cloud processing-local execution", and the local WIFI voice controller is used for execution. The WIFI voice controller processes the input-stabilization-output of the power supply and the reception-execution of data.

[0037] The WIFI voice controller is connected to the gateway control panel, enabling local network configuration and connection to the in-vehicle WIFI router. As Figure 16 shown, the gateway control panel is a special network configuration panel for RVs, and its structural principle is as Figure 14 shown, and its electrical schematic diagram is as Figure 15 shown. Electrical working principle: The external power supply of 9~16V is input and converted into 5V and 3.3V through the power conversion chip LM317AG-TN3-R. Among them, 5V provides power supply for the touch switch chip TTP233D-HA in the gateway control panel. The user's finger generates an induction signal through touching the gateway control panel and provides it to the ESP32-S3-WROOM-1U chip through the touch switch chip TTP233D-HA as a trigger switch for network configuration. In addition, the ESP32-S3-WROOM-1U chip can control two status indicator lights to provide the user with the network configuration status message. The gateway control panel adopts a simple and convenient interactive operation panel. Users who use it for the first time can also quickly get started with zero learning cost and set up and bind the in-vehicle WIFI router through the gateway control panel, thus building an environmental association of local-cloud-local; the gateway control panel is the first step in building the in-vehicle usage scenario architecture. Through the data intercommunication after the connection and setting of the gateway control panel, the WIFI router and the WIFI voice controller, local and cloud network communication is realized, and then the WiFi router and the WIFI voice controller are bound.

[0038] During use, as Figure 2As shown, the user wakes up the Xiaodu AI device in the car by saying "Xiaodu, Xiaodu". The entire logic chain involves devices and platforms including a Wi-Fi voice controller, the Xiaodu AI device, a gateway control panel, a Bluetooth amplifier, a Baidu cloud server, and an AI semantic cloud platform. The AI ​​semantic cloud platform server connects to the Baidu cloud server. The Xiaodu AI device replies "Here". The user then gives a voice command to control the in-car devices, such as "Turn on the ambient lights". After receiving the voice control command, the Xiaodu AI device performs semantic conversion on the AI ​​semantic cloud platform. The AI ​​semantic cloud platform then sends the semantically converted command to the Wi-Fi voice controller via the network. The Wi-Fi voice controller then sends a CAN command to the CCM module. The CCM module controls the ambient lights to turn on, and the AI ​​voice device replies "Ambient lights are on", thus ending the operation.

[0039] The Baidu Cloud server, Xiaodu AI device, vehicle-mounted WIFI router, Bluetooth amplifier, Living CAN bus, and other devices involved in this utility model are all existing devices that can be purchased from the market. The WIFI voice controller and gateway control panel, supported by the above two hardware products and their running application software, realize the unique voice usage scenario of the RV smart living cabin.
