Design And Implementation Of Vehicle Feature Data Management System

With the rapid development of the national economy and the continuous improvement of people's living standards,cars are no longer luxury goods.Most families have the economic ability to purchase vehicles,and the car ownership has increased year by year.However,as the number of vehicles increases,various traffic problems become more serious.The traditional method of monitoring and identification is done by the human eye,that is,by manual observation to identify the license plate number,vehicle model,vehicle type and other characteristics,this method is time-consuming and labor-intensive,and inefficient,has not kept up with the rapid development of society.In view of the above situation,this thesis designs and implements the vehicle feature data management system.The system is implemented in a cross-platform Java language.The foreground uses the EasyUI framework,and the background uses the Spring+SpringMVC+Mybatis integration framework to improve the scalability of the system.The entire system uses a standard software development process.First,a detailed analysis of the requirements of the system was carried out,and the characteristics of different users using the system were analyzed.Then,according to the demand analysis,the system is designed,and the system is divided into three modules: picture management module,vehicle picture detection module and vehicle picture display.The picture management module includes picture addition,uploading and deleting;the vehicle picture detection module is divided into an image server function and a vehicle picture detection function;the vehicle picture display module is divided into a vehicle picture display function,a vehicle detail information display function and a vehicle query function.Since the detection algorithm of the system is provided by the dynamic link library file,the JNA technology is used to implement the call of the dynamic link library file,thereby realizing the detection of the vehicle picture.The system implements load balancing based onNginx server and realizes dynamic and static separation,so that when users request static resources,they directly return from the Nginx server without requesting the web server,which improves the throughput and access efficiency of the system.Finally,the development of each module is completed.After the system test,each module can be used normally,the whole system runs well,and the expected effect is achieved.The use of the system reduces manpower investment and improves the efficiency of the relevant staff.
