Design And Implementation Of Mobile Client Software For Vehicle Monitoring System Based On Android

In recent years,with the rapid development of China's economy,China's information technology development has also made great progress.5G has been officially commercialized in China in 2019,which has accelerated the development of the Internet of things in China.A variety of intelligent products are constantly emerging,intelligence has been integrated into every aspect of people's life.At present,the number of cars in our country is increasing,and people's requirements for cars are getting higher and higher.The hope is that cars will be smarter and provide a better driving experience.In order to meet the needs of the public,this paper designs and implements a vehicle monitoring software based on android.The software has the function of displaying vehicle operation information in real time.The main achievements of this paper are as follows:(1)The module of receiving vehicle data is designed and implemented on android device.The module adopts UDP protocol for real-time data transmission.When the android terminal receives the packet,it parses the data and stores the data in the SQLite database.(2)The graph display module and vehicle positioning display module are designed and implemented.The graph display module queries the vehicle's speed,gear position,left and right indicator data from the SQLite database,and judges the data,and then displays the results graphically.In this way,users can avoid direct contact with digital information to improve their actual experience.The vehicle location display module queries the latitude and longitude data of the current vehicle from the SQLite database,and then calls the interface of baidu map to display the location of the vehicle on the android device,so that the user can clearly understand the current location and route.(3)The vehicle data display module and the vehicle speed line chart display module are designed and implemented.In order for the user to query more vehicle information,the vehicle data display module will query all vehicle data from the SQlite database and display it on the android device.The vehicle speed line graph display module queries the speed data from the SQlite database and displays it on the android device.These data are presented in theform of line charts,which can show the trend information of vehicle speed and help users improve their driving skills.
