Embodiment 1

[0059] Such as figure 2 As shown, a corresponding LIFI module is set in the driving road of the expressway, wherein the LIFI module is set in the substructure of the street lamp to send and receive LIFI data.

[0060] When the user is driving on the expressway, he chooses to call Xiaoming by voice or manual touch button. At this time, the mobile terminal will judge that this is a voice service according to the content of the instruction, so it can judge the signal strength corresponding to the voice service. The obtained signal strength is -50dBm, which is greater than the range of the signal strength threshold of -95 to -85dBm. Therefore, it shows that the call quality at this time is better, and at this time, the second communication mode will be adopted, that is, the mobile terminal communicates through the cellular base station, which is the normal communication mode. If the signal of the mobile terminal becomes weak during the driving of the vehicle, and it is less than...

Embodiment 2

[0062] Such as Figure 2-3 As shown, a corresponding LIFI module is set in the driving road of the expressway, wherein the LIFI module is set in the substructure of the street lamp to send and receive LIFI data. A LIFI transceiver is installed in the headlights of the car to transmit and receive optical signals. It can send out modulated optical signals, and can also receive optical signals for demodulation. The user's mobile terminal can be connected to the on-board control computer, or the converter or modem of the peripheral device through wired or wireless means.

[0063] When the user is driving on the expressway, he chooses to call Xiaoming by voice or manual touch button. At this time, the mobile terminal will judge that this is a voice service according to the content of the instruction, so it can judge the signal strength corresponding to the voice service. If the signal strength at this time is -96dBm and is less than the range of -95 to -85dBm, then the first commu...

Abstract

According to an onboard communication method designed by the present invention, a data transmission mode can be selected according to a current signal strength, so that a user can communicate with anLIFI device on a high-speed road, especially in places with poor mobile signals, to improve the stability of signal transmission, to increases the connection rate of calls and data, and improves userexperience.

Description

technical field [0001] The present invention relates to a communication method, and more specifically, to a vehicle-mounted communication method, a computer-readable storage medium and a vehicle-mounted terminal. Background technique [0002] LiFi is the abbreviation of "Light Fidelity", which is a new wireless data transmission technology developed by the famous British physicist Harald Haas, which can use ordinary lighting to complete the whole process. At the same time as turning on the lights in the room, the user also turns on the Internet connection. The device, called LiFi, can be used to transmit wireless data from TV band "white space" or unused satellite signals. The invention transmits data by changing the frequency of the light in the room lighting, and can transfer data at more than 10Mb per second, which is comparable to a typical broadband connection. [0003] When the vehicle is driving at high speed, due to the Doppler effect, the signal of the mobile phon...
