Problems solved by technology

[0002] The way and process of Internet of Vehicles service is realized through the communication between the mobile terminal and the service platform. Common communication methods include: voice call, data transmission through voice data channel, SMS transmission and IP data transmission. Each communication method has its own Different application environments and defects corresponding to non-adaptive environments, for example, the DTMF method of voice data channel transmission data, its disadvantage is that there are fewer character types to be transmitted, which is suitable for occasions with fewer character types; while the mobile communication network-based Such as short messages and IP data are easily affected by the wireless transmission environment, especially in the adjacent and cross areas of wireless coverage of different base stations, information transmission will not be smooth, resulting in unstable and unreliable information channels
Therefore, it is difficult to meet the needs of different communication environments with a single terminal data channel
[0003] On this basis, the Chinese invention patent "A Dual-channel Instruction Receiving Method for Veh

Embodiment 1

[0056] Embodiment 1, the mobile terminal switches the data channel by itself.

[0057] see figure 2 As shown, it is a flowchart of Embodiment 1 of the self-adaptive data transmission method of the Internet of Vehicles terminal of the present invention, and the process is:

[0058] Step a1, the mobile terminal 1 is turned on, which sets the connection addresses of the various data channels on the processing server side and the cyclic order of the data channels between the mobile terminal 1 and the processing server; when the user has a vehicle service demand , activate the client software placed in the mobile terminal 1 (such as in a mobile phone or a car navigator), and perform the following operations in the mobile terminal 1, please refer to image 3 As shown, it is a flow chart of the mobile terminal preset data channel cycle sequence according to the embodiment of the method for adaptive data transmission of the Internet of Vehicles terminal of the present invention,

Embodiment 2

[0082] Embodiment 2, the processing server controls the mobile terminal to switch data channels.

[0083] see Figure 6 As shown, it is a flow chart of Embodiment 2 of the self-adaptive data transmission method of the Internet of Vehicles terminal of the present invention, and the process is:

[0084]Step b1, the mobile terminal 1 is turned on, which sets the connection addresses of the various data channels on the processing server side and the cyclic order of the data channels between the mobile terminal 1 and the processing server; this process is the same as the above-mentioned embodiment One is the same.

[0085] Step b2, the processing server 3 communicates with the mobile terminal 1 through the selected data channel.

[0086] Step b3, the current data channel cannot meet the communication requirements, and the corresponding processing server has a communication failure, and the processing server 3 sends a control instruction to change the data channel to the mobile te...

Abstract

The invention relates to a terminal self-adaptive data transmission system and method for an Internet of Vehicles service. The method comprises the following steps that a mobile terminal is started and sets link addresses of various data channels of a processing server end, and loop sequence orders of the data channels between the mobile terminal and the processing server; the processing server is in communication with the mobile terminal through the current data channel; if the current data channel cannot meet the communication requirement, whether a communication fault exists between the mobile terminal and the processing server is judged, if yes, the mobile terminal judges which data channel meets the communication requirement according to the preset data channel changing conditions, and the current data channel which cannot meet the communication requirement is switched to the data channel which meets the communication requirement. The terminal self-adaptive data transmission system and method for the Internet of Vehicles service can achieve real-time switch of the data channels.

Description

technical field [0001] The present invention relates to a terminal adaptive data transmission system and method for Internet of Vehicles services, in particular to a terminal adaptive data transmission system and method for distributed Internet of Vehicles services. Background technique [0002] The way and process of Internet of Vehicles service is realized through the communication between the mobile terminal and the service platform. Common communication methods include: voice call, data transmission through voice data channel, SMS transmission and IP data transmission. Each communication method has its own Different application environments and defects corresponding to non-adaptive environments, for example, the DTMF method of voice data channel transmission data, its disadvantage is that there are fewer character types to be transmitted, which is suitable for occasions with fewer character types; while the mobile communication network-based Such as short messages and IP...
