Design And Implementation Of Police Vehicle Remote Monitoring System Based On Android

The Vehicle Management business space and management methods is constantly upgrading as the unceasing reform and improvement of Vehicle Management System in our country.It has become a trend for public security departments to reform vehicle management utilizing information management technology.Making the information more systematic,standardizing information transmission and information form is the work contents that vehicle management of the public security department will begradually realized.Carrying out the construction of vehicle management systemin the traffic management business of the public security department will help to improve the efficiency of vehicle management and the management level of data business.The thesis started with status quo of GPS navigation system home and abroad.Pain points of the current vehicle navigation system has been dug out by analysis the frame work,software and hardware,working theory and function modules,and put forward with a remote monitoring solution adopting cellphone with Android operating system as terminal to collect vehicledata,which transmits data with 4G network,and servers in monitoring center will analyze and process data uploaded to functions such as realize real-time monitoring,replay and alarm reporting.Followed by in-depth analysis of key technologies needed for remote monitoring system,namely Android system,Geographic Information System(GIS),Global Positioning System(GPS),4G wireless communication technology.The system overall framework is designed with MVC model and based on J2 EE software development platform,and integrated Android intelligent mobile phone,ELM327,vehicle OBD system into a vehicle terminal to collect vehicle dynamic data,and developed the system center data base by SQL Server2012,Build monitoring center server with B/S architecture,In order to complete the analysis and processing of the uploaded data.Implement the functions of each module by programming and Combining the function requirements of vehicle remote monitoring system,It is more convenient for users to operate the system by developing the interface of the system according to the characteristics of human-computer interaction.Finally,the wireless transmission,real time acquisition,monitoring data receiving and parsing data,displaying driving status,simulating vehicle alarm,and tracing historical playback are tested with the real vehicle debugging experiment.
