Design And Implementation Of Electronic Police System Data Processing Subsystem

Electronic police system is a kind of road-information collecting and vehicle monitoring system.The system greatly improves the safety awareness of automobile drivers,and also reduces the probability of traffic violations and the workloads of the traffic police.Data processing subsystem is the core of the electronic police system.The subsystem monitors the divers' violations by analyzing the vehicles' moving information.And then it composes the illegal pictures which are uploaded to the control cener subsystem.Firstly,in order to find out the problems,the background research of the electronic police system was investigated.Based on the domestic and foreign research status,the whole structure of thesis was established.The related techniques of the data processing subsystem were introduced the part of the technique introduction in detail.Then,by using the object-oriented design methods,the requirements of several important functions were analyzed in detail such as the system information management function,the data storage management function,the illegal capture function and so on.According to the overall requirements and modules' requirements analysis,the architectural design of the subsystem was given a general introduction,and then the careful design principles and process of the subsystem information management modular,the vehicle illegal capture modular and the data storage management were described in detail.In the database design phase,the data relationships and tables were established by using database related knowledge and E-R diagrams.Finally,the detection interface and software structure were briefly described.The implementation of the parameter setting modular,the vehicle detecting modular,the illegal judgment modular and the illegal picture synthesis modular were explained emphatically by using interface,key code and flow chart.In the system testing phase,the software testing principles were introduced,and then the data processing subsystem was tested by the test cases which were designed by testing principle.Through the function and performance testing of the data processing subsystem,it can meet the needs of the traffic management department of road management,and also it has many anvantages such as friendly interface,simple operation,fully function,good stability,reliability and so on.So the subsystem will effecticely reduce the drives' violations.
