Abstract

The invention discloses a data transmission method and a system based on a secure digital (SD) compound device in car networking. The system comprises a vehicle navigation device, the SD compound device, a peripheral small terminal, a mobile phone with a Bluetooth module, and a service desk, wherein the vehicle navigation device is connected with the SD compound device through a secure digital input output (SDIO) port, the SD compound device and the peripheral small terminal are connected through the 2.4 G network, the peripheral small terminal is connected with the mobile phone with the Bluetooth module through the Bluetooth network, and the mobile phone with the Bluetooth module is communicated with the service desk through the global system for mobile communications (GSM) network. According to the data transmission method and the system based on the SD compound device in the car networking, information to be transmitted can be modulated to a dual-tone multifrequency (DTMF) code and placed on a sound channel and then transmitted between mobile devices through the GSM, and therefore simple data interaction is achieved between a back stage and the vehicle navigation device.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a data transmission method and system based on dual-tone multi-frequency SD composite equipment in the Internet of Vehicles. Background technique [0002] In the traditional Internet of Vehicles. The information communication between the background and the car navigation (vehicle machine) is based on the GPRS channel and SMS channel of the mobile phone network. These two methods have two disadvantages. One is that the car navigation must have a built-in GSM / GPRS module and a mobile phone SIM card. This will increase the hardware cost on the one hand, and on the other hand, the management of the mobile phone SIM card is also very troublesome. Another drawback is that additional costs are incurred whether via GPRS or SMS channel. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] The purpose of the present invent...
