Design And Implementation Of Intelligent Driving Monitoring System Based On Embedded System

At present,the electric vehicle intelligent driving industry has entered a stage of rapid development.To truly achieve intelligent driving technology,we need to use the remote monitoring system to collect various driving information data on the way of intelligent driving of the vehicle.This is an important method for detecting the safety performance indicators of intelligent driving of electric vehicles,and it provides the necessary guarantee for the stable operation of the vehicle at a later stage.This paper is based on the needs of intelligent driving technology developers for data collection during the journey of intelligent driving of vehicles,and it proposes a set of embedded electric vehicle intelligent driving monitoring system.In this paper,ARM cortex-A9 is used as the main control chip,and the hardware configuration of the corresponding functions is added to finally realize all the functions of the system.The designed system is mainly composed of three parts:(1)Vehicle-mounted terminal: This terminal is mainly used for data collection,including CAN bus module and GPS module.OBU can realize the function of collecting the bottom driving control data of the car through the CAN bus module,and the function of collecting the real-time position information of the vehicle through the GPS module.(2)Wireless communication terminal: This terminal is mainly used for data communication,including 4G module and V2 X module.The 4G wireless module enables OBU to quickly and steadily send driving control information and vehicle position information to remote mobile terminals through the UDP protocol.The V2 X module is mainly a V2 X antenna,which can realize the position communication in a unified frequency band between vehicles.(3)Remote mobile terminal: The terminal is mainly an Android App,which can receive and process the data sent by OBU for intelligent driving research and development personnel to observe and analyze the driving information data.The measurement accuracy and real-time performance of the terminal equipment designed in this paper basically meet the relevant requirements put forward by the intelligent driving technology developers,and have high scalability and popularization and application value.
