Description

Technical Field

[0001] The present invention relates to the field of in-vehicle voice communication, and in particular to a Bluetooth headset intercom solution for a passenger car entertainment screen. Background Art

[0002] Currently, smart cars on the market all support functions such as voice recognition and voice broadcasting, and are equipped with built-in microphones, which are generally placed on the ceiling. Entertainment systems such as smart cockpits are mainly based on the Android system, which provides users with a standard microphone data reading interface and can be encoded into AAC format.

[0003] The triple-screen smart cockpit design allows for independent entertainment for the front passenger. Bluetooth headphones connect to the smart cockpit's front passenger screen via Bluetooth protocols like AAC and SBC. Audio data from the screen can then be transmitted to the headphones for playback. Existing technologies enable connectivity between Bluetooth headphones and the front passenger side of a car's smart cockpit, creating independent entertainment spaces for the driver and front passenger. However, this also creates communication difficulties: When connected, the front passenger cannot clearly hear the driver's conversation due to the inherent noise cancellation (supported by most headphones) and the inherent music playback.

[0004] For example, a "Bluetooth headset intercom system" disclosed in Chinese national patent documents has a publication number of CN102547486. This patent requires the installation of a first transceiver module, a second transceiver module, a data control module and a power module between two Bluetooth headsets to achieve intercom between the two Bluetooth headsets. This is costly and cannot exchange important information in the first place. Summary of the Invention

[0005] The present invention aims to solve the problem in the prior art that there are communication barriers between the driver and the co-driver of a car, and the co-driver cannot receive important information in time, and provides a Bluetooth headset intercom solution with the co-driver's entertainment screen in the car.

[0006] In order to achieve the above object, the present invention uses the following technical solutions:

[0007] A Bluetooth headset intercom solution for a car's passenger entertainment screen includes the following steps:

[0008] Step S1: The driver presses the steering wheel voice button;

[0009] Step S2: Determine the current connection status of the co-pilot Bluetooth headset;

[0010] Step S3: Start the service reading module and send the microphone information to the co-pilot recognition module;

[0011] Step S4: The co-pilot module receives the microphone data, and the co-pilot passenger hears the conversation information between the driver and the driver through the Bluetooth headset.

[0012] After the driver presses the steering wheel voice button for at least 2 seconds, the cockpit system enters the Bluetooth headset conversation mode.

[0013] The cockpit system exits the voice recognition mode, releases the microphone occupied by the voice mode, starts the service to read the microphone input, sends the microphone information to the co-pilot recognition module, and the co-pilot entertainment screen starts the service reading module, so that the co-pilot module receives the microphone data. The co-pilot passenger hears the conversation information sent by the driver through the Bluetooth headset and conducts normal conversation and information exchange. This method reduces the information screening process of the intermediate control module, directly communicates between the driver and the co-pilot, reduces device costs, saves user time, and communicates in a timely manner to avoid problems that harm the interests of both parties.

[0014] Preferably, the intercom device includes a central control main screen and a co-pilot entertainment screen, wherein the central control main screen is installed on the right side of the main driver's cabin, and the co-pilot entertainment screen is installed in the middle of the co-pilot cabin, and the central control main screen and the co-pilot entertainment screen are signal connected.

[0015] The intercom between the driver and the co-driver is realized through the connection between the central control main screen and the co-driver entertainment screen. The central control main screen and the co-driver entertainment screen are connected by signals, and the Bluetooth module is set in the co-driver entertainment screen. When the driver presses the voice button for at least 2 seconds and initiates the intercom, the driver's voice signal is received by the MIC module in the car, and sent to the co-driver entertainment screen through the central control main screen, and then the voice signal is sent to the Bluetooth headset through the co-driver entertainment screen, so that the co-driver can obtain the driver's voice information; three on-board display screens are set, and the purpose of voice information transmission between the driver and co-driver cockpits is achieved through information interaction on the display screens.

[0016] Preferably, step S2 includes:

[0017] Step S21: The steering wheel voice button is pressed, and the system determines whether the current passenger Bluetooth headset is connected;

[0018] Step S211: If connected, the voice recognition module exits the service and releases the microphone;

[0019] Step S212: If not connected, return to step S11 and continue to determine the connection status.

[0020] The driver can trigger the intercom mode by pressing and holding the voice button on the steering wheel for at least 2 seconds, and keep pressing the voice button to maintain the intercom mode. After releasing the button, the intercom mode will be exited. When entering the intercom mode, the intelligent cockpit voice module will temporarily exit the voice recognition mode, but will record the sound made by the driver and co-driver and store the voice in the information storage unit to facilitate subsequent voice calls; if the Bluetooth headset is connected to the microphone, after the voice module exits the voice recognition mode, the system will directly read the input data of the microphone and convert the voice input data entered by the driver into AAC format encoding; if the microphone does not recognize or cannot recognize the connection of the Bluetooth headset, the connection result will be fed back to the driver and the connection status judgment mode will be re-entered.

[0021] Preferably, the service reads the microphone input and encodes it into AAC format, which is then transcoded and sent to the co-pilot module. AAC format encoding is an audio compression algorithm with a high compression ratio. It adopts a multi-channel approach and uses a low-complexity description method, which saves internal storage space in the car and allows the voice recognition module to store more voice information after recognition. It is convenient for storage, has a large information storage capacity, is easy to load and communicate in real time, saves the cost of using the voice module, increases its service life, and improves the efficiency of information interaction between the driver and co-pilot.

[0022] Preferably, step S3 includes:

[0023] Step S31: The co-pilot module receives microphone data and pauses the current media source playback;

[0024] Step S32: The co-pilot module creates new background media;

[0025] Step S33: The new background media plays the AAC data.

[0026] The microphone data and background entertainment data are processed separately, and the voice information of the main driver is fed back to the co-pilot in time, while the entertainment function of the co-pilot entertainment screen is not turned off, thereby increasing communication efficiency.

[0027] Preferably, the service reading module stores and records the AAC data of the new background media playback to form a historical database, identifies the dialect, automatically translates it into Mandarin, and displays it on the co-pilot entertainment screen and the central control main screen, so as to facilitate accurate communication between the main and co-pilot. After the main driver exits the intercom mode (releases the voice button), the main driver's voice module restores the voice recognition mode, and the co-pilot continues to return to the original media playback status, so that the co-pilot screen can continue to perform entertainment functions.

[0028] Therefore, the present invention has the following beneficial effects:

[0029] Utilizing the car's voice recognition microphone and steering wheel button operation, the driver's conversation is directly transmitted to the Bluetooth headset through the cockpit system, ensuring that the passenger receives accurate conversation information;

[0030] The in-car intercom system includes a central control main screen and a passenger entertainment screen. Through the signal connection between the display screens, the voice content of the driver's voice is transmitted to the passenger's Bluetooth headset using the voice microphone in the car;

[0031] The central control main screen establishes front and back ends, making it convenient for the co-pilot to return to the entertainment function after receiving the voice message from the main driver, thereby improving the co-pilot's riding experience. BRIEF DESCRIPTION OF THE DRAWINGS
