Design Of Police Vehicles Command System Terminal Based On Mobile Communication

Since twenty-first Century, with the traffic development is more and more quickly, thevehicle with the explosion forms increased, various traffic situations, security incidents alsoincreased in geometric form. These factors make the vehicle dispatching system to traditionalgradually basically modernization, the emergence of new dispatching system of intelligent andasked to provide solutions to improve the complicated traffic situation. If the wireless positioningtechnology and geographic information system and other new technology and traditionaldispatching systems are combined, these technologies can help road vehicles to complete theroute optimization, real time communications traffic, road guide, detection of rescue and specialcircumstances, for the vehicle information management laid the prerequisite.The practical problems of the police vehicle management to meet the new form in the focuson the design of the terminal, a vehicle command system based on mobile communicationnetwork module composite geographic information system basic, completed the hardware circuitof the whole flight and software operation. This design can be fully autonomous can receive GPSsignal, through the analysis of operational planning out the exact path, the matching is performedby GIS system, realized the real-time traffic control, special offers to deal with sudden incidentsof police vehicles solve ability, to maximize the use of resources, reduce all kinds of traditionalproblems of police and the police repeatedly not timely.The system used WinCE embedded operating system, compared with the traditional SCMfrom technology, the design has a corresponding time is short, fast, fast and flexible operation,strong pertinence and multi thread control etc.. This system has improved the traditional systemfunction expansion, upgrade cost and lack of intelligence shortcomings, especially to increase thesoftware module, scalable and support the upgrade, more add even display and language function.This system effectively optimizing resources, set computer technology, wireless communicationtechnology, has the advantages of low cost and effective advantages.Several graft and host operation etc. the main part of this paper, the whole framework ofterminal hardware system, with geographic information system. The user can implement human-computer interaction through the terminal of the multi thread technology; application of ARMbeyond the processing speed MCU fundamentally, improve the user waiting time, and solves theshortcomings of small storage unit, can be saved on the communication operation data, analysis of relevant data at any time convenient user. With technology to achieve the real-time monitoringof vehicles, running track drawing, comparison of related data, and be able to coordinate therelevant vehicle real-time query.
