Multichannel vehicle networking gateway system and communication method thereof

Abstract

The invention discloses a multichannel vehicle networking gateway system and a communication method thereof. The system is arranged on a vehicle-mounted platform of a vehicle, and comprises a master control module, a network switch, a 3G Modem, a WLAN network bridge and a universal serial port, which are respectively connected with the master control module, wherein a plurality of application devices and communication devices are externally connected with the network switch; the 3G Modem and the WLAN network bridge are respectively connected with an antenna; the universal serial port is connected with a sensor network gateway; the WLAN network bridge emits wireless signals through the antenna to realize networking among different vehicles. According to the multichannel vehicle networking gateway system disclosed by the invention, the vehicle networking is adopted to realize mutual use of communication resources of the vehicles, so that resource waste can be avoided.

Description

technical field [0001] The invention belongs to the technical field of vehicle communication, and in particular relates to a multi-channel inter-vehicle networking gateway system and a communication method thereof. Background technique [0002] Due to the characteristics of large bandwidth, long communication distance, and little influence from the ground, satellite communication has been widely used in emergency communication, large-capacity broadcasting, and private network establishment in various industries. The application of satellite communication technology in emergency communication occasions is usually installed and integrated on the vehicle platform or portable communication platform. When installed and integrated on the vehicle platform, it can form a vehicle satellite emergency command platform, especially in earthquakes, fire protection, environmental protection, and government emergency response. and other fields have good application space.

AI Technical Summary

Problems solved by technology

[0003] Generally speaking, in addition to the integrated satellite communication system, GPRS, CDMA, Wimax and other communication systems will be installed on the vehicle emergency platform to form a multi-channel command platform. When it is put into application, it is usually not used by a single vehicle, but through multiple When vehicles carry out joint emergency response, the communication resources of the vehicle-mounted platforms are different, and the application resources of the vehicle-mounted platforms are also different. Therefore, if a vehicle can only use the communication resources of its own vehicle, some applications will need to wait for use. Communication resources, some communication resources are empty and unused, resulting in waste of resources
