The Application Research Of Gps/gprs Technology In The People's Armed Police Combat Command Decision Support System

With the rapid development of information technology, the traditional patterns of armed police combat and command decision making are unable to meet the speed and response combat requirements of the New Era Armed Police Force. GPS positioning technology, GPRS technology, and GIS technology are increasingly used in Armed Combat Command Decision-making system. The integration of these technologies can satisfy the dynamic-positioning and real-time-tracking needs of police vehicles and personnel on duty, which help commanders make correct and scientific decision and lay foundation for digital operations of the troops.Firstly, this paper has a deep research and analysis on GPS,GPRS,GIS as well as other relative technologies and literature. And then, according to the actual requirement of the Armed Police Force combat duty, a whole design of the application of the GPS, GPRS technology in the PASS (police on duty-pass) is proposed. In addition, the paper explains the data processing on GPS Terminal and the communication manner between GPRS-based GPS Terminal and Command Center. Finally, the PASS system is designed and implemented. The system consists of three parts:processing of terminal data, GPRS communication and Command Control Center. Through the cooperation of these three-parts, the system meets the needs of the PASS. This system, which realized remote real-time monitoring, decision-making and management, information mutual transmission between mobile terminal and command control center, not only utilizes the real-time positioning function of GPS Terminal and the advantages of GPS Terminal together with GIS system to intuitively track and display geographic data, but also explores the characteristics of GPRS technology, such as high-speed, real-time and wide range coverage of network.
