Design And Implementation Of Command And Dispatch System Based On Digital Trunking Communication

In order to carry out requirements of modern police work by public securitywireless communication platform to integrate voice, data, pictures, video and otherservices. The system of GIS geographic information will be combined, and the systemof GPS global positioning will be as useful information resources available to thepublic security commandcenter of decision-making and on duty police handling the case,so as to improve the combat effectiveness. In this context, this paper design andresearch-based digital trunking communication command and dispatch system.Firstly, the subject source, subject, background, and Command and Control SystemCommand and Control System of the status quo at home and abroad, and demandanalysis of command and dispatch system for data acquisition, command and dispatchmanagement information, basic functions, system use cases and performancerequirements, and analyze the data flow of the system.Secondly, the analysis of the data set communication technology, GIS informationsystems and systems development techniques, design, including the overall architectureof the Command and Control System, the system overall structure, function modules,network topology design, and design the system model, data flow diagrams, the finaldesign of the system database tables, ER relationship diagram with stored procedures,detailed design business system management data manipulation processes.Finally, the command and dispatch system functions, respectively, log basicinformation on the dispatch console system maintenance, marshalling informationmaintenance, scheduling functions, members of tree management, parameter settings,the map operation, the operation of mobile users call operations, log managementmodule achieved; system test analysis with patients and running performance tests onthe function of the system, come the test results. The tests show that the realization ofthe Command and Control System meets the requirements analysis requirements.With digital trunking technology, the establishment of the Command and ControlSystem is a general trend, the command and dispatch management and service platformsynergies by the public security departments, can directly and indirectly generate publicsecurity department management effectiveness. GIS-based integrated design anddevelopment, greatly improves the Command and Control System of practicality and convenience, Collaborative Scheduling for the realization of the network of publicsecurity departments to improve the level of command and dispatch, command anddispatch personnel for public security system to provide strong technical support.
