4G vehicle smart terminal system

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.

Description

technical field [0001] The invention relates to a 4G vehicle-mounted intelligent terminal system, which belongs to the technical field of network communication. Background technique [0002] Modern cars are constantly developing towards electronization, and cars will become the largest electronic product. With the continuous updating of science and technology, the car networking system has become the development direction of the car network. The Internet of Vehicles comprehensively perceives and processes vehicle condition information and road traffic information through the integration of modern sensing technology, communication technology, electronic technology and computer technology, and realizes the interaction between people and cars, people and clouds, and people and people. The environment is becoming more and more intelligent. Especially with the rise of big data and cloud systems, the application of various systems in the information age can be better realized th...

Problems solved by technology

Most of the vehicle-mounted 3G and 4G routers can only provide wireless access to the Internet. Although they solve the problem of Internet access in the vehicle environment, they do not have the functions of intelligent driving such as driving data statistics, fault diagnosis, location services, and abnormal reminders; The OBD car equipment does not support the car WLAN Internet access function, which cannot meet the requirements of the car mobile environment Internet access
