Vehicle-mounting T-Box based on DSRC and low-altitude satellite communication

Abstract

The invention provides vehicle-mounting T-Box based on DSRC and low-altitude satellite communication. The vehicle-mounting T-Box based on DSRC and low-altitude satellite communication comprises a dataacquisition unit and a wireless communication unit which are connected mutually; the data acquisition unit comprises a slave processor as well as a data memory and a CAN communication module which are connected with the slave processor; and the wireless communication unit comprises a master processor as well as a DSRC communication module, a 4G communication module, a low-altitude satellite communication module, a WiFi/BT module, a GPS/Big Dipper positioning module, an RTC real-time clock module, a battery management unit, a memory module, a voice module, a coding and decoding module, a man-machine interaction module and a security chip. Dynamic information real-time interaction and sharing between the vehicle and the vehicle, the vehicle and people as well as the vehicle and a roadside base station are realized by applying a DSRC communication technology. By the whole time-space based traffic dynamic information acquisition and fusion technology, vehicle safety active risk avoiding control and intelligent coordinated management on the road can be realized and development of smart transportation can be promoted well.

Description

technical field [0001] The invention belongs to the technical field of Internet of Vehicles, in particular to a vehicle-mounted T-Box based on DSRC and low-altitude satellite communication. Background technique [0002] With the development of data communication and multimedia business needs, a new generation of mobile communication technology that meets the needs of high-speed mobile data transmission, mobile computing and mobile multimedia operations—low-altitude satellite communication technology has begun to emerge. Traditional satellites are far away from the ground, with a distance of 36,000 kilometers. The network delay is large and the connection is slow, so it is not suitable for high-speed network transmission, and the low-altitude satellites are only deployed at 1200 kilometers above the ground, which can replace the ground base station tower. From a high-altitude view, the traditional ground base station The signal propagates almost horizontally, and will be bloc...
