Description

Technical Field

[0001] The utility model relates to a recreational vehicle and an interactive control system thereof, belonging to the field of recreational vehicle interactive control. Background Art

[0002] With the development of domestic automobile technology and the automobile industry, cars are no longer just a means of transportation for users. More and more car users are beginning to pay attention to the convenience and comfort of the car. Therefore, the use of smart central control screens instead of traditional physical buttons has become the current development trend and has begun to be fully applied in the field of family cars.

[0003] However, in the RV field, most function switches are still controlled by physical button switches. Whenever the user needs to control a function switch to turn on or off, he needs to go to the switch to close or disconnect it, which is very inconvenient. In addition, the center console with traditional buttons requires customized button molds. The button mold shell made of metal is expensive, and if you need to add function buttons, you can only customize the mold again, resulting in low convenience and low cost performance.

[0004] In order to solve the above problems, the Chinese utility model authorization announcement document with the authorization announcement number CN210488297U provides a centralized monitoring device for after-installed equipment for RVs based on a human-machine interactive screen. Through high integration, the monitoring and control of equipment on the RV can be displayed and realized through the human-machine interactive screen, solving the problem of cumbersome operation of the traditional RV button center console. However, since there is no user terminal, when the user needs to use related functions, he still needs to move around the human-machine interactive screen, which is less convenient and has a poor user experience.

[0005] The Chinese utility model authorization announcement document with authorization announcement number CN212965771U provides an intelligent RV control system based on a controller and a display control panel directly connected to the controller for communication. This utility model document discloses a user terminal connected to the controller through an interconnection module, and a display control panel with a voice recognition function, which solves the problem that the user needs to move to the vicinity of the human-computer interaction screen when controlling the RV function. However, the RV control system disclosed in this utility model can only recognize simple voice control commands, and the user voice control experience is poor; and this utility model directly connects the display control panel to the controller, resulting in poor controller expansion capabilities, and the controller needs to be replaced when other functions need to be added.

[0026] The idea of ​​the utility model is to set a gateway and communicate with the RV controller and the human-machine interaction screen through the gateway, realize information interaction between the human-machine interaction screen and the RV controller through the gateway, and the user issues instructions on the human-machine interaction screen, and the instructions are transmitted to the RV controller through the gateway. Through this architecture, when adding the control function of the human-machine interaction screen and the RV controller, there is no need to replace the controller or the controller interface, which effectively solves the problem of poor expansion capability of the RV control system in the prior art.

[0027] In order to make the purpose, technical solutions and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] The idea of ​​the utility model is to set up a gateway, respectively communicate and connect the RV controller and the human-machine interactive screen through the gateway, and realize information interaction between the human-machine interactive screen and the RV controller through the gateway. Through this architecture, when adding the control function of the human-machine interactive screen and the RV controller, there is no need to replace the controller or the controller interface, which effectively solves the problem of poor expansion capability of the RV control system in the prior art.

[0029] This embodiment uses the smart home gateway as the gateway used, the smart home platform as the smart home server, the voice cloud platform as the voice server, the RV smart screen as the human-computer interaction screen, and the mobile phone APP as the user terminal to provide a clearer and more complete explanation of the utility model.

[0030] An embodiment of an interactive control system for a motorhome:

[0031] like Figure 1 The illustrated interactive control system for a motorhome includes a motorhome smart screen, a smart home gateway, a voice module, a voice cloud platform, a smart home platform, a mobile phone APP, a motorhome controller and a load. The load includes monitoring, speakers, speaker amplifiers, inverters, awnings, air conditioners, lithium batteries, I / O modules, three-in-one fast charging, two-in-one DC-DC transformers, lighting, water, heating, security sensors and drawer compartments.

[0032] Among them, the RV smart screen supports Bluetooth connection, the voice module supports Bluetooth and WIFI communication, the smart home gateway integrates 4G, Bluetooth and CAN bus communication, the RV controller supports two-way 485 bus and two-way CAN bus communication, and the I / O module supports the input and output of sensor signals, voltage signals, and switch signals.

[0033] Among them, the RV smart screen and voice module can be connected to the smart home gateway via Bluetooth, the voice module and the voice cloud platform are connected via WIFI, the voice cloud platform and the smart home platform are connected via 4G, the smart home platform and the smart home gateway are connected via 4G, and the mobile phone APP and the smart home platform are connected via Ethernet; the smart home gateway is also connected to the RV controller via the CAN bus. Since the baud rate of the awning is greater than the baud rate of the monitoring, speaker amplifier and inverter, the RV controller is connected to the monitoring, speaker amplifier and inverter respectively through the first 485 bus, and the RV controller is connected to the awning through the second 485 bus; since the baud rate of the air conditioner and I / O module is lower than the baud rate of the lithium battery, three-in-one fast charging and two-in-one DC-DC transformer, the RV controller is also connected to the lithium battery, three-in-one fast charging and two-in-one DC-DC transformer through the high-speed CAN bus, and the RV controller is also connected to the air conditioner and I / O module through the low-speed CAN bus; the I / O module is also connected to lighting, water use, heating, security sensors and drawer cabins and other equipment.

[0034] Among them, the voice module recognizes the user's voice and converts the user's input voice information into text information. When the recognition result meets the relevant conditions of the local analysis of the offline command word, it directly analyzes and generates the command. After the command is generated, it directly communicates with the smart home gateway via Bluetooth. The smart home gateway is connected to the RV controller through the CAN bus to control the corresponding load; when the recognition result does not meet the relevant conditions of the local analysis of the offline command word, the text information is sent to the voice cloud platform via WIFI. The voice cloud platform recognizes the command and connects with the smart home platform through Ethernet. The smart home platform sends the command to the smart home gateway through 4G communication. The smart home gateway is connected to the corresponding load of the RV controller through the CAN bus and controls it. After the device is successfully controlled, the data is returned to the voice module. The voice module broadcasts the execution result through the speaker connected to the power amplifier. At the same time, the execution result can also be displayed when the RV smart screen is turned on.

[0035] By connecting the smart screen and the smart home gateway via Bluetooth, the position of the smart screen in the car can be changed, making the location of the smart screen more flexible, and even allowing users to customize the location, which can greatly improve the user experience; connecting the voice module and the smart home gateway via Bluetooth, the position of the voice module can be freely set, so that the voice module can be set at any location where the user may issue a voice command. When the voice signal input by the user is a formatted sentence, the processor in the voice module directly transmits the voice signal to the smart home gateway via Bluetooth, and then controls the corresponding load through the RV controller; when the voice signal input by the user is an unformatted voice signal, the processor in the voice module determines that it is an unformatted voice signal, and then transmits the signal to the voice cloud platform via WIFI transmission. The voice cloud platform determines the formatted voice signal corresponding to the unformatted voice signal. After the judgment is completed, the formatted voice signal corresponding to the unformatted voice signal is transmitted to the smart home gateway via the smart home platform, and then the corresponding load is controlled through the RV controller. By setting up a voice cloud platform, the user's voice command becomes more free, which greatly improves the user experience.

[0036] Among them, the mobile phone APP integrates the control of common functions of RVs (lighting, air conditioning, heating, etc.) and common information display (water volume, electricity volume, etc.). Click the control panel on the mobile phone APP and send it to the smart home cloud platform through the mobile phone 4G communication. The smart home cloud platform sends the command to the smart home gateway through 4G. The smart home gateway communicates with the RV controller through the CAN bus. After receiving the command, the RV controller can control the load in the car through the CAN bus, 485 bus, and I / O module and return the execution result of the control command to the mobile phone APP and the RV smart screen. At the same time, the I / 0 module communicates the collected water and electricity display data to the RV controller through CAN communication. The RV controller reports it to the smart home gateway in real time through CAN bus communication. The smart home gateway transmits it to the smart home platform through 4G communication. After opening the mobile phone APP, the vehicle status data is automatically synchronized.

[0037] By setting up a mobile phone APP as the user terminal, users can control and monitor the functions and status of the RV on their mobile phones, greatly improving the user experience.

[0038] Among them, the lights connected to the I / O module include the ceiling lights, atmosphere lights, reading lights, night lights, outdoor lights, etc. on the RV; the water used by the I / O module includes clean water volume, gray water volume, black water volume sensors, water pumps, hot water solenoid valves and other equipment; the warm air connected to the I / O module includes the fuel heater and radiator on the RV and its control solenoid valve; the security sensors connected to the I / O module include CO alarms, smoke alarms and gas alarms, temperature and humidity sensors, etc. The data sensed by the above sensors are displayed on the RV smart screen for users to view.

[0039] The SOC, power, voltage and current of the lithium battery; the output voltage, output current and charging power of the charger; the input and output voltage, current and power of the DC-DC and other power data are also displayed on the RV smart screen for users to view.

[0040] The RV controller realizes monitoring, power amplifier and inverter switch control and inverter output voltage, current and load power data acquisition through the first 485 bus; the RV controller realizes the extension and retraction function of the awning through the second 485 bus.

[0041] Through multi-branch settings, loads with different baud rates use different 485 buses or CAN buses. Separate settings make the control of the load more precise and increase the utilization rate of electrical energy in the RV.
