Design And Implementation Of Police Car Command System Based On GPS And GIS

With Chinese economy quickly developing, people have higher and higher standard of living, increasing policeman’s requirements.At the same time criminal rate become higher. The use of advanced equipment means a serious impact on the economic development and people’s daily life, therefore, accelerate policeman’s system is necessary. 110 command center of FuZhou as the Emergency Command departments, rapid Alarm, fast scheduling, rapid response alarm and the feedback overall objective of development must solve the problem. Police car is the main means of transport of the police officers out of the police received a call for help from the command center connected to police officers call to the relatively long time between the mobilization of police cars dispatched intensive urban road network, and severe traffic congestion, and a direct impact on the speed of the police, the efficiency of decision-making relatively low; alarm lack of a more intuitive understanding of police intelligence and the surrounding situation information resource distribution, and all this will be a fatal blow to the key 110 Alarming time; Fuzhou Bureau of the implementation of the three police unity requirements of the road police car 24-hour patrol, sent out of the police car, are difficult to make effective monitoring and management. Therefore, a new set of police vehicle monitoring and management system need to be builded.The technology of GPS、GIS and their application in in the police car monitoring are researched in this project. the research and the application of GIS in the police car monitoring. Alarming live tracking of police vehicles, spatial analysis specific functionality and strong visual performance capability are studed By GPS global positioning. Police car information and spatial information are integraed, by monitoring police car in the spatial distribution and real-time operating conditions, analysis of its internal relations, rational allocation and scheduling of resources, in order to achieve the monitoring of police cars.The following content is including in this thesis: overview of domestic and international GPS, GIS technology development status and trends; research on the system, on the basis of the needs analysis, given the overall design of the police car monitoring system based on GPS-GIS, and system requirements analysisthe structures function the module summary of the hardware and software configuration, system database design, the key technologies are briefly described; achieve dynamic GPS data processing GPS signal access, conversion of GPS coordinates and a GPS receiver sends process; According to Fuzhou Bureaupavement 24-hour patrol of the police car needs, a vehicle cross-border algorithm, the vehicles parked analysis algorithm and the vehicle signal analysis algorithm are designed. At the same time geographic analysis techniques to police car the timeout docked is achieved.
