The foregoing implementations are described in detail below with reference to specific embodiments and accompanying drawings.
As shown in fig. 1, an embodiment of the present application provides a vehicle communication method that may be applied to a first vehicle, and may include S101 to S103 described below.
S101, the first vehicle acquires target data.
Wherein the target data includes at least one of: head view data, audio-video data, and notification information.
S102, the first vehicle determines the emission wavelength of the laser communication module according to the category of the target data.
S103, the first vehicle transmits the target data to the second vehicle through the laser communication module at the transmission wavelength.
The above-described vehicle communication method is specifically described below by three embodiments.
Example 1
Under the condition that the target data is head car vision data and the first vehicle is a head car, the first vehicle can acquire a vision picture in front of the vehicle through a camera, and receive a sweep frequency signal reflected by the environment through a lens; and then carrying out video fusion on the visual field picture and the sweep frequency signal to obtain the head car visual field data. When the target data is head view data and the first vehicle is not a head vehicle, the first vehicle may receive the head view data transmitted from the front vehicle and play a view screen corresponding to the head view data.
Specifically, as shown in fig. 2, during the running of the N vehicle queues, the rear vehicle cannot observe the head-to-head view. It is therefore necessary to establish a front-to-rear vehicle communication link to communicate the head-to-vehicle vision data in real time to the rear vehicle to facilitate the rear vehicle to share the vision in front of the head-to-vehicle. Taking the vehicle 1 as the head car as an example. The forward sensing system of the vehicle 1 may acquire a forward field of view, forming head-mounted field of view data in image data format. After the head-to-vehicle vision data stream is processed by the vehicle-mounted network equipment of the vehicle 1, 1310 nm-band laser can be sent through the vehicle tail laser communication system to point to the laser radar in the front-end sensing system of the vehicle 2. The laser radar in the forward sensing system of the vehicle 2 receives the backward laser communication video data stream of the vehicle 1, and after the backward laser communication video data stream is processed by the vehicle-mounted network equipment in the vehicle 2, the visual field picture of the head vehicle 1 can be played on the local vehicle-mounted screen. Meanwhile, the vehicle 2 can also transmit the head-to-vehicle vision data through a vehicle 2 tail laser communication system. In this way, the view from the head car 1 can be received and presented sequentially from the vehicle 2 to the vehicle N in the N vehicles.
The signal flow in the above-described field of view transmission example is described in detail below with reference to fig. 3. As shown in fig. 3, when the first vehicle is a head vehicle, the linear chirp can modulate the laser to stably and continuously output 1550nm laser light, thereby obtaining a triangular linear frequency modulation signal. The modulation signal passes through a split coupler, and one path of modulation signal is scanned and output through a collimator and is used for detecting the front view environment; the other path is used for mixing local oscillation light and echo signals. The lens can receive the sweep frequency signal in the bandwidth of 5GHz around 1550nm reflected by the environment, and the sweep frequency signal is mixed with local oscillation light after passing through the demultiplexer. The mixed electric signals are processed by a data processing circuit and output to an upper computer for video fusion. The data collected by the camera is two-dimensional content, and the data is output to the network equipment through the upper computer after video fusion with the three-dimensional data of the laser radar. The network equipment comprises functions of local termination service and transparent transmission service, can convert video signals into video pictures through an audio-video system, realize local play and can also transparent transmit the video signals to a laser communication transmitter of a rear vehicle. The tail laser communication transmitter modulates the video signal and drives the fixed-frequency laser to emit at 1310nm wavelength. When the first vehicle is not in the head, the lens may receive the 1310nm wavelength signal and reach the detector via the demultiplexer. The system is connected to network equipment after being amplified by the amplifier, the network equipment can convert video signals into video pictures through an audio-video system, and can realize local play and can continue to be transmitted to a laser communication transmitter of a rear vehicle, so that the head-car visual field data can be sequentially transmitted to each vehicle.
It should be noted that, fig. 3 only aims at the above-mentioned field transmission example, and different channels can be used in other examples by arranging the demultiplexer and the multiplexer.
Example 2
Under the condition that the target data are audio and video data, the first vehicle can also receive a communication request sent by the second vehicle before the first vehicle acquires the target data; and establishes a communication connection with the second vehicle in accordance with the communication request. Thereby establishing a basis for receiving audio and video data input by a user.
Specifically, as shown in fig. 4, the second vehicle may initiate a communication request, and after the communication request is processed by the TCP/IP protocol package and the network device, the second vehicle may transmit addressing through the front and rear transmitting modules. After receiving the communication request of the first vehicle, the second vehicle can establish an end-to-end hard communication pipeline after three times of handshaking, after full duplex communication between the first vehicle and the second vehicle, the audio-video call between the first vehicle and the second vehicle can be initiated by one party to terminate the request, and after four times of negotiations, the audio-video call can be terminated.
Optionally, the rear receiving module corresponds to a front transmitting module channel, and the front receiving module corresponds to a rear transmitting module channel. The front emission module can use 1560nm channels, the channel bandwidth can be greater than or equal to 50GHz, the rear emission module can use 1530nm channels, and the channel bandwidth can be greater than or equal to 50GHz.
Example 3
In the case where the above-described target data is notification information, the first vehicle may also perform deceleration, steering, and safe distance calculation tasks after the first vehicle transmits the target data to the second vehicle.
Illustratively, as shown in fig. 5, the above notification information is exemplified as a dequeue notification. The first vehicle may issue a dequeue notification, and the network device may package the dequeue notification into a general message encoding format and send the dequeue notification to the front and rear vehicles of the first vehicle, respectively. The network device may send a dequeue instruction to the control module, so that the control module assists the first vehicle in performing tasks such as decelerating, steering, and safe distance calculation. The second vehicle can receive the dequeue notification of the first vehicle, and after being decoded by the network device, the dequeue notification is respectively sent to the control module of the second vehicle, so that space for changing lanes and steering is vacated for the first vehicle, and the front and rear safe vehicle distances are reserved. When the first vehicle finishes dequeuing, the front and rear vehicles can reestablish formation connection, and the dequeuing state is kept. The information transmission channel of the front transceiver module of the automobile can be 1330nm, and the information transmission channel of the rear transceiver module of the automobile can be 1360nm.
It should be noted that, in an embodiment, the second vehicle may include at least one vehicle. I.e. the at least one vehicle may in turn receive a dequeue notification of the first vehicle and make room for the first vehicle.
Alternatively, the notification information may include a fault code. Different fault codes may cause the control module to perform different actions. Referring to table 1, fault codes corresponding to different fault types, and actions to be performed.
TABLE 1
Note that, the fault code in table 1 may be a hexadecimal four-bit combination or a hexadecimal two-bit combination. The embodiment of the present application is not limited thereto.
The embodiment of the application provides a vehicle communication method, which can determine the emission wavelength of a laser communication module according to the category of target data and emit the target data to a second vehicle by the emission wavelength, so that the data transmission rate can be improved by utilizing the large bandwidth advantage of a wavelength division system, and meanwhile, detouring can be avoided, back-to-back transceiving can be realized among vehicles, thereby reducing the time delay to the maximum extent and ensuring the driving safety.
