With the continuous improvement of automobile production capacity and people's living standard, the automobile becomes the tool of riding instead of walk of ordinary family more and more, but with the continuous improvement of automobile rate of utilization, traffic accident incidence is also continuously rising. Therefore, many domestic research institutes have been devoted to the research of active safety techniques for automobiles in recent years. In the driving process of the automobile, in order to prevent accidents, not only is safe driving required, but also the driving conditions of surrounding automobiles need to be observed and known in time so as to take measures to avoid the accidents in time, for example, a driver needs to change the light of far and near light according to the driving states of two vehicles during meeting so as to avoid dazzling during meeting, and therefore the accidents are reduced as much as possible. For example, when overtaking on a road, if it is necessary to prevent a sudden lane change of a preceding vehicle, it is necessary to perform a flashing light or a whistling operation, but the preceding driver does not always notice such an operation as a warning.
In the prior art, vehicles running on a road cannot be communicated in time, so that effective communication between vehicle owners and vehicle owners cannot be achieved, and further misunderstanding among vehicle owners and road rage caused by illegal lane occupation, slow running, lane passing, lane changing and the like are inevitable.
LiFi is the abbreviation of Light Fidelity, a brand new wireless data transmission technology developed by great physicist Harrad-Haas in England, and the whole process can be completed by using common lighting. The user has also opened an internet connection while turning on the room lights. This device, known as LiFi, can be used to transmit wireless data from the "white space" television band or unused satellite signals. The invention transmits data by changing the frequency of the room lighting, the data transmitted per second is more than 10Mb, and the invention is comparable with the typical broadband connection. The Chinese patent application 'LIFI lamplight-based unidirectional transmission device' (invention patent application No. 201410582927.0 publication No. CN105634592A) discloses a unidirectional transmission device for carrying out unidirectional transmission on data through optical signals by using an LIFI technology, which comprises a sending end communicated with a sending module and a receiving end communicated with a receiving module, wherein the sending module is physically isolated from the receiving module; the sending module comprises an LED and is used for sending optical signals; the receiving module comprises a photomultiplier tube and is used for receiving the light signal sent by the LED and counting and detecting the light signal; the LED and the photomultiplier are oppositely arranged. In order to reduce the interference of stray light in the signal transmission process, the technical scheme needs to arrange the LED and the band-pass filter on the same straight line, and arrange the LED and the band-pass filter in the same sealed and light-shielded box body. This makes the technical solution of the patent application unable to satisfy the requirement that two cars moving at high speed and meeting at random mutually transmit the driving state information. The invention patent application "automobile driving data interactive system based on LiFi and its vehicle signal lighting device" (application number: CN201610574908.2, publication number: CN106059666A) discloses that the driving information of automobile is transmitted by optical signal through LiFi chip placed in the lamp; after the automobile running oppositely or following oppositely receives the signal, the vehicle control computer system analyzes and processes the running data to obtain the real-time running state information of the opposite vehicle, so that effective measures can be taken in time to prevent vehicle collision or rear-end collision traffic accidents. However, this solution cannot realize data exchange between two vehicles, that is, two vehicles cannot communicate with each other. The invention discloses a vehicle-mounted interconnection device and method and a vehicle (publication number: CN105959022) in China, and discloses an optical signal detection unit, a first processing unit and a prompting unit, so that a detected optical signal is converted into an electric signal, further converted into instruction information corresponding to the optical signal, and the instruction information is prompted. The vehicle interconnection device includes: the receiving unit, the second processing unit and the optical signal transmitting unit are used for processing the received command signal to convert the command signal into an electric signal, converting the electric signal into an optical signal and transmitting the optical signal. The embodiment of the invention can acquire the driving intentions of other vehicle owners in time, realize interconnection and intercommunication among vehicles, and reduce the occurrence of congestion or traffic accidents and the like; the driving intention of the user can be transmitted to adjacent vehicle owners, interconnection and intercommunication among vehicles are realized, and the occurrence of congestion or traffic accidents and the like is reduced. However, in the scheme, a plurality of LED sending modules are required to be arranged to transmit the vehicles in all directions, and the system is inconvenient for users to operate and high in cost.
Aiming at the current situation, a system capable of realizing real-time communication between vehicles is designed, so that effective communication between vehicle owners is increased, misunderstanding is avoided, road rage is avoided, and the like, and the system is very necessary and has certain popularization significance.

Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced otherwise than as specifically described herein, and thus the scope of the present invention is not limited by the specific embodiments disclosed below.
The vehicle includes a vehicle-mounted light transmission module that transmits a modulated light signal in the form of light and a vehicle light reception module that receives the light signal and then demodulates the light signal to extract effective information.
Fig. 1 shows a flow diagram of a vehicle-mounted interconnection method according to the present invention.
As shown in the figure, the invention provides a vehicle-mounted interconnection method, which comprises the following steps:
the vehicle light receiving module receives a light signal;
and analyzing the optical signal to obtain content information and direction information, and displaying or playing the content information and/or the direction information.
As shown in fig. 2, the vehicle light receiving module may be disposed inside the vehicle headlight module, above the roof of the vehicle, or inside the vehicle tail light module, or inside the rear view mirror light module on the side of the vehicle, and the vehicle light receiving module may be disposed inside all the light modules, so that the problem of receiving in the 360-degree direction of the plane can be solved. As to the orientation in which the receiving module is arranged, a person skilled in the art may specifically arrange it for different needs and scenarios. The vehicle receiving module can be provided with a light prism module for receiving light information in more directions so as to ensure the effectiveness and stability of light transmission.
In the embodiment of the present invention, the direction information includes: one or more of right front, right back, right left, right, left front, left back, right front and right back.
It should be noted that the direction information may be more than the above 8 directions, and those skilled in the art may set more directions according to actual needs to perform accurate positioning and inform the receiving end which sending end vehicle sent the information.
As shown in fig. 3, in the embodiment of the present invention, after analyzing the optical signal to obtain the content information and the direction information, and displaying or playing the content information and/or the direction information, the method further includes:
generating feedback information;
packing the feedback information into a feedback data packet;
and determining the direction of the sending end of the optical information according to the direction information, and then indicating the vehicle-mounted optical transmission module to send the feedback data packet according to the direction.
It should be noted that, the whole data packet is composed of two parts, one part is a data packet header; one part is a content part, which consists of corresponding content bits. The whole data packet can adopt binary data or quaternary and octal data, and can be specifically set according to actual needs. And generating a corresponding data packet header according to the direction information, wherein the data packet header is 2-5 bits. Feedback information bits may also be included in the header of the data packet to inform the receiving end that the data information has been successfully received. The direction information is transmitted in the packet in order to inform the vehicle receiving the data from which direction the data is transmitted, and the receiving vehicle can know from which direction the data is from after analyzing the entire packet.
It should be further noted that the feedback information is used by the receiving end to inform the transmitting end that the data has been successfully received. The feedback information may be a bit flag or a specific packet. And packaging the feedback information into a feedback data packet. And determining the direction of the sending end of the optical information according to the direction information, and then indicating the vehicle-mounted optical transmission module to send the feedback data packet according to the direction. For example, the transmitting-end vehicle a transmits data to the vehicle B in front of the left, the vehicle B generates feedback information after receiving the data, then packages the feedback information into a feedback data packet, and determines that the transmitting-end vehicle a is the right rear side relative to the vehicle B according to the direction information, then drives the vehicle optical transmission module to transmit the feedback information to the vehicle a in the right rear side, and informs that the vehicle a has successfully received the data.
As shown in fig. 4, in the embodiment of the present invention, the interconnection method further includes:
analyzing the optical signal and extracting the flag bit information of the sending times;
acquiring the sending times of a sending end according to the sending time flag bit information;
and if the sending times exceed the preset times threshold, increasing the sending power of the vehicle-mounted optical transmission module, and sending the feedback data packet.
It should be noted that, a transmission number flag bit may also be set in the transmitted data packet, where information of the transmission number is stored. Therefore, the sending end and the receiving end can analyze the received data packet to obtain the sending times. And judging whether the times exceed a preset time threshold, if so, increasing the sending power of the vehicle-mounted optical transmission module, and sending the feedback data packet. According to the method of the embodiment, the validity of the transmission data can be better ensured, if the environment of optical transmission is poor, and the number of times of transmission by the sending end is found to be large after the receiving end receives the data packet, it indicates that there may be feedback information that the sending end does not receive the receiving end in the previous times of transmission, or the information sent by the sending end is not received by the receiving end. Therefore, the condition that the sending end sends the information for multiple times exists, once the receiving end determines that the sending times exceed the threshold value, the sending power of the vehicle-mounted optical transmission module can be increased, the light intensity is ensured to be increased, and the sending end can well receive the information.
More specifically, the number threshold is 2-10. Based on the applicant's experience and experimental data, an optimal threshold number of times of 2-10 can be found. When the threshold is set to 1 time, the problem that the transmission power is increased due to data retransmission is likely to occur, and at this time, the retransmission times are not large, and it is not necessary to immediately increase the power, which may cause unnecessary power consumption. When the threshold is set too large, since multiple data retransmissions have been performed before, the optical transmission environment may be very poor, and it is likely that the optical information cannot be delivered if the retransmission is continued. It is not necessary to go through more than 10 data retransmissions, the power consumption of transmission is also increased, and it is not necessary to set the threshold value to 10 times in consideration of the vehicle type environment and situation.
In the embodiment of the present invention, further, the method further includes:
after the feedback data packet is sent, if the feedback information that the feedback data packet is successfully received is not received within a preset time threshold, the feedback data packet is sent again; the time threshold is 0.5-5 seconds.
After the vehicle transmits the optical signal, the vehicle further includes: and receiving a feedback data packet sent by the opposite vehicle to indicate that the opposite vehicle successfully receives the optical signal. And if the optical information is not successfully transmitted within a preset time threshold, defaulting that the optical information is not successfully transmitted or a feedback data packet transmitted by the opposite vehicle is not successfully received. In this case, it is necessary to transmit the data packet of the optical information once again, and increase the transmission power of the optical transmission module to ensure that the signal transmitted this time can effectively reach the opposite vehicle, and increase the transmission number flag bit in the header of the data packet to indicate the number of times of transmission, and if the number of times of transmission is large, it indicates that the optical transmission environment is poor; if the number of transmission times is small, the optical transmission environment is good. The set sending times zone bit can also enable the opposite vehicle to know the sending times, if the sending times are more, the power of the optical sending module is increased when the opposite vehicle feeds back, and therefore the vehicle where the user is located can successfully receive the feedback signal.
In the embodiment of the invention, the time threshold is 0.5-5 seconds, and the optical signal data packet is retransmitted when the feedback data packet is not received within 0.5-5 seconds. Preferably, the time threshold is 1 second.
In the embodiment of the invention, the threshold value of the sending times is 2-10 times, and after the sending times exceeds the threshold value of the sending times, the sending power of the vehicle-mounted optical sending module is enhanced. Preferably, the threshold value of the number of transmissions is 3. A threshold number of terminations may also be set, and when this threshold is reached, the retransmission of the optical information is terminated. The threshold number of termination times is 11-20 times, preferably 12 times. The magnitude of the transmit power boost is 20-50%.
In the embodiment of the present invention, further, the method further includes:
and after the optical signal is successfully received, starting an indicator lamp corresponding to the vehicle to prompt that the optical signal sent by the vehicle at the sending end is successfully received.
In this embodiment, after the receiving end successfully receives the optical signal, an indicator light corresponding to the vehicle is started to prompt the sending end that the optical signal sent by the vehicle is successfully received. For example, the sending end may send feedback information after sending data to the vehicle ahead, and the vehicle ahead may start a corresponding indicator light of the vehicle to prompt the sending end that the optical signal sent by the vehicle is successfully received. The tail lamp can flash rapidly for 3 times, and the rear fog lamp can be turned on and flash for 3 times. The response mode of the vehicle lamp can be set by those skilled in the art according to actual needs, but any changes or substitutions which are not imaginable by creative work are covered in the protection scope of the invention.
The displaying or playing of the content information is specifically displaying and playing through one or more of the following modes: a speaker, a display screen, a head-up display, HUD, or a front windshield. For example, the content information may be played back in a speaker mounted on the vehicle, the content information may be displayed on a display screen, and the like. The content display and prompting mode can be set by a person skilled in the art according to the actual needs, but any changes or substitutions which are not thought of by the creative work are covered in the protection scope of the invention.
Example one
The method comprises the steps that a sending end vehicle A runs at the rear, an in-vehicle user wants to send data to a vehicle B at the front left, the vehicle B generates feedback information after receiving the data, then the feedback information is packaged into a feedback data packet, and the sending end vehicle A is determined to be the rear right relative to the vehicle B according to direction information, then a vehicle light sending module is driven to send the feedback information to the vehicle A at the rear right, and the vehicle A is informed that the data are successfully received.
The feedback information is used by the receiving end to inform the transmitting end that the data has been successfully received. The feedback information may be a bit flag or a specific packet. And packaging the feedback information into a feedback data packet. And determining the direction of the sending end of the optical information according to the direction information, and then indicating the vehicle-mounted optical transmission module to send the feedback data packet according to the direction. After the vehicle a receives the feedback information, the "successful transmission" can be displayed on the display screen of the vehicle a or the "successful transmission" voice can be played in a voice mode, so that the user can know that the vehicle B has successfully received the light information sent by the vehicle a.
In this embodiment, after the vehicle B receives the light information sent by the vehicle a, the tail lamp of the vehicle may be controlled to continuously flash 3 times, and after the user in the vehicle a behind sees the flashing lamp, the user may know that the vehicle B has successfully received the information.
Example two
The method comprises the steps that a sending end vehicle A runs at the rear, an in-vehicle user wants to send data to a vehicle B at the front left, the vehicle B generates feedback information after receiving the data, then the feedback information is packaged into a feedback data packet, and the sending end vehicle A is determined to be the rear right relative to the vehicle B according to direction information, then a vehicle light sending module is driven to send the feedback information to the vehicle A at the rear right, and the vehicle A is informed that the data are successfully received.
The vehicle a receives the feedback packet transmitted from the opponent vehicle to indicate that the opponent vehicle successfully received the optical signal. And if the optical information is not successfully transmitted within a preset time threshold, defaulting that the optical information is not successfully transmitted or a feedback data packet transmitted by the opposite vehicle is not successfully received. In this case, it is necessary to transmit the data packet of the optical information once again, and increase the transmission power of the optical transmission module to ensure that the signal transmitted this time can effectively reach the opposite vehicle, and increase the transmission number flag bit in the header of the data packet to indicate the number of times of transmission, and if the number of times of transmission is large, it indicates that the optical transmission environment is poor; if the number of transmission times is small, the optical transmission environment is good. The set sending times zone bit can also enable the opposite vehicle to know the sending times, if the sending times are more, the power of the optical sending module is increased when the opposite vehicle feeds back, and therefore the vehicle where the user is located can successfully receive the feedback signal.
For example, the time threshold is 1 second. The transmission number threshold is 3. After the vehicle a transmits the optical signal, it waits for the reception of the feedback information, and if the feedback information is not received within the time threshold of 1 second, it is assumed that the vehicle B does not receive the optical information, and the optical information is transmitted again. If no feedback information is received after more than 3 retransmissions, the transmission power may be increased, for example, by 20%. When the termination times reach 12 times, if the feedback information is not received yet, the optical information transmission is terminated, which indicates that the optical signal transmission environment is poor at this time and the transmission requirement cannot be met.
The method of the embodiment is also applicable to the feedback information sent by the vehicle B.

The invention also provides a vehicle-mounted terminal, which comprises a processor and a memory, wherein the memory stores an executable program run by the processor, and is characterized in that the processor executes the steps of any one of the methods when running the executable program.
The vehicle-mounted interconnection and intercommunication method designed by the invention can enable vehicles at intervals or in driving to communicate, and avoid road rage caused by misunderstanding. The lifi technology has the characteristic of one-way transmission, namely, data transmission can be carried out only in an illuminated place, so that the method can also be used for quickly positioning the vehicles of the opposite side needing to be communicated, so that the optical transmission module carries out optical signal transmission according to a specific direction, the vehicles of the opposite side can receive optical signals better, the embarrassment that other vehicles at the periphery receive the same optical signals due to too large light irradiation range can be avoided, and the effect of directional transmission is achieved. The method of the present invention can also increase the effectiveness of optical communication, increase the transmission power when the communication environment is poor, and ensure the reliability of communication during the driving of the vehicle through the form of handshaking.
