Research On The Vehicles Tracking System Based On Gps+gsm Double Technology Localization

With economic development, criminal offenses involving vehicles have also shown a high-tech, intelligent and professional characteristics, in order to cope with the increasingly serious law and order situation, the implementation of police training and technology must be based on strategic thinking, through the high-tech means to improve security civilian police to track targets and command and dispatch capabilities.In this study, the work of public security personnel location information in the pursuit of access to difficult practical problems, design and development of the GPS + GSM dual-technology location tracking system. The system uses a series of high-tech, such as electronic mapping technology, mobile communication technology, electronic navigation technology, database technology and achieve the goals and pursuit of the suspect's whereabouts in a unified real-time display on the map interface.This system is composed of police used to track location and tracking system and the portable device of two parts. Police station with the tracking system on the surface location (LBS) and air satellite positioning (GPS) system, a combination of pairs of technical positioning systems, using front-end all forms of location tracking devices, mobile communications networks and background data processing, service system to help police officers in the pursuit of work to be fast and accurate target location information being tracked and status information to guide investigators to quickly track the goal of raising the public security department rapid response capability. Portable locating and tracking devices compatible with the police tracking system can be realized with the positioning...
