Design And Implementation Of Intelligent Terminal Based On Internet Of Vehicles

With the development of intelligent transportation and Internet of Vehicles technology,more and more attention has been paid to the intelligent management of vehicles.As an important part of Internet of Vehicles,intelligent terminals have become the key research object with its huge commerciality and development space.In this context,this subject has designed a set of intelligent terminal equipment that integrates vehicle communication,anti-theft notification,positioning and navigation,vehicle diagnosis,exhaust gas monitoring,driving behavior analysis and other functions.The specific research work is as follows:1.Researched 4G communication and the Internet of Vehicles unified communication protocol to realize vehicle communication;used Zig Bee module and camera module to collect sensor and image data to realize the anti-theft monitoring function;researched the positioning principle of Beidou satellite positioning module and the satellite positioning unified communication protocol;The OBD-II system has an in-depth understanding of the bottom layer and analyzed the 9 OBD diagnostic modes and PIDs to obtain the request commands corresponding to the required diagnostic data,and requests data from the OBD module through the Bluetooth module.2.Software development based on the Android platform.The three pages of login,registration,and personal center are used to complete the input and binding functions of the owner and the vehicle information.The remote management platform realizes intelligent unified management;when the sensor data is abnormal,the Android API is called to achieve Image collection and SMS sending function,while calling the positioning module to transmit the remote management platform in real time,to realize the intelligent reminder of the car owner and remote monitoring of the vehicle location when theft occurs;analyze the latitude and longitude and time data,and realize the vehicle positioning on the page through Baidu Map API,Car navigation function;the diagnostic information collected by the OBD Bluetooth module is displayed on the page and sent to the remote management platform,and the received fuel economy behavior analysis data is organized into a report and displayed on the page to realize the intelligent diagnosis function of the car.Through the above research work,this paper not only realizes the basic function of positioning and navigation of traditional on-board terminals,but also expands and realizes the functions of vehicle communication,intelligent anti-theft reminder and remote vehicle monitoring,vehicle data and exhaust gas diagnosis,and driving behavior analysis.The terminal equipment is more intelligent.
