Vehicle information transmission device and method

Abstract

The invention discloses a vehicle information transmission device and a method. The device comprises a wireless transceiver module used for connecting with the 3G network and establishing a circuit domain voice link with an information processing system, an OBD interface module used for connecting with an OBD interface of a vehicle to acquire first vehicle information, and an analysis processing module used for processing the first vehicle information into vehicle information data in a PCM frame format and sending the vehicle information data through the circuit domain voice link to the information processing system. Through the device, the vehicle information is transmitted through a voice channel of the mobile communication network, a utilization rate of the 3G network is improved, circuit domain resources of the 3G network are fully and reasonably utilized especially, equipment disposition and later maintenance are convenient, and problems of 3G network redundancy waste and 3G network circuit domain resource idleness are solved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a vehicle information transmission device and method. Background technique [0002] In recent years, the automobile industry has developed rapidly in China, and the number of passenger vehicles has increased by more than 1 million for two consecutive years. As the number of car users continues to rise, car information security and car-connected information processing have become an important part of the current car development. All major car manufacturers and car equipment suppliers are targeting this huge market. How to gather a large amount of car information in one large Big data processing under the cloud platform is a problem that needs to be considered. [0003] At the same time, as of the end of 2014, the number of 4GLTE base stations in China has exceeded 500,000, the network covers more than 300 cities, and the number of LTE users has reached 14 million. The adv...

Problems solved by technology

The advantages of LTE's high speed and low tariffs have prompted more Chinese people to choose 4G networks, which will inevitably lead to a waste of 3G network resources that have been fully covered before. Therefore, how to make full use of the widely deployed and mature 3G networks will be a consideration for operators. big problem

[0004] The existing vehicle information transmission device transmits vehicle information to the remote information processing system, usually using 4G network, resulting in waste of 3G network

At the same time, when the existing mobile devices use the 3G network, they also usually use the PS (Packet Switch, Packet Switching) domain of the 3G network for data transmission, causing the CS (Circuit Switch, Circuit Switching) domain of the 3G network to be idle.

Ultimately, 3G network resources cannot be fully and rationally utilized
