Research And Implementation Of Official Vehicle Management System Based On Beidou Positioning

At present,the level of informationization of China’s official vehicle management varies,and most of the official vehicle information registration systems can only realize static information management such as configuration attribution and asset registration of the official vehicles under their jurisdiction,but lack dynamic management capability,and many vehicles that have been connected to the satellite positioning management system are using GPS system,which is restricted by foreign technology and has the risk of leakage.Through the research and construction of the Beidou positioning-based official vehicle management system,we can strengthen the management of official vehicles,explore the socialization of official vehicles,realize the intensive use of official vehicles,and effectively reduce the use of public vehicles in the ‘three public’ expenses.Based on the Bei Dou satellite navigation system,this paper combines navigation technology and software programming technology to develop a practical Bei Dou-based positioning management system for official vehicles.The system is divided into two parts:hardware and software.The hardware part is mainly the vehicle-mounted Bei Dou terminal including Bei Dou positioning module,communication module and main control module;the software part mainly includes the database,the location service platform and the application software system.The vehicle-mounted terminal is used for vehicle satellite positioning,vehicle status information collection and platform command sending and receiving,realizing the functions of positioning and navigation,status detection,information collection,remote control and information sending for official vehicles,etc.The EC20 R2.0 module is used in the vehicle terminal to realize Beidou positioning and 4G wireless communication functions,and the module also integrates voice playback,SMS sending and receiving functions;the ARM Cortex-M3 series chip is used as the main controller chip and the highest operating frequency of ARM Cortex-M3 chip is up to 72 MHz with rich external interfaces.The location service platform mainly provides vehicle positioning,GIS geographic information and other services,realizing the functions of receiving and storing vehicle terminal positioning information,map loading,map browsing,location display,track playback and so on.The application software system is composed of Web terminal and mobile terminal,based on the map engine of the location service platform,it realizes the visual management of official vehicles,realizes online supervision of official vehicles,location positioning,track playback,vehicle management,reservation service and other functions.The system developed is highly maintainable and easy to use.Through this Beidou positioning-based official vehicle management system,each government unit can realize the standardization of the use process and management of official vehicles,and the standardization of repair and maintenance and troubleshooting.The system has the functions of Beidou navigation and positioning,early warning and forecast,track playback,etc.,and can remotely detect the vehicle status and control the vehicle.Through the statistical analysis of vehicles,personnel,trajectories and other multi-directional data to achieve lean management and further improve the level of management of official vehicles.The system provides convenience for the use,management and dispatch of official vehicles,and has certain social and economic benefits.
