Abstract

The invention discloses a 4G vehicle smart terminal system. According to the invention, a vehicle OBD device and a vehicle 4G-WIFI router are integrated together, so that functions of online fault diagnosis, vehicle state monitoring, abnormity warning, location service, traveling data statistics and the like can be realized, and a function of the vehicle 4G-WIFI router can be realized at the same time. In an aspect of hardware, a vehicle terminal device includes a microcontroller and different functional modules. A vehicle OBD data code is obtained through the smart OBD module. Vehicle location information is obtained through a GPS module. Dormancy and awakening induction information and collision detecting information are obtained through a three-coordinate accelerometer module. Network access is provided to an in-vehicle mobile internet device through a WLAN module. Internet access is realized through a 4G module. Data is sent to a background server. In an aspect of software, the invention adopts a [miu]C / OC-II embedded operation system for accurate real time response to tasks.
