Design And Implementation Of Vehicle Tracking System Based On Card Port Data

In the time of high-speed development of Internet technology such as cloud computing and big data,computer technology is more and more widely used in various fields.It is urgent for public security organs to change their traditional working mode and business process.As an important part of the information construction of the Public Security Office,the vehicle tracking system based on the card-port data provides a variety of tracking functions for police officers by mining a large number of car-passing data,which makes it more convenient and efficient for police officers to track vehicles.Therefore,it is crucial to build a stable and safe vehicle tracking system.The topic of this paper comes from the project of "Juyun Police Big Data".The system collects the passing information identified by high-definition cameras at each gate of a city,stores the passing information in a distributed way,and fully excavates the information contained in the massive passing pictures captured by the card-port cameras.According to the actual scenes encountered by police officers,nearly 30 simple and efficient combat functions are summarized,which makes the reconnaissance and defense work modular and desktop-based,and drives the transformation of the police mode.The content of this paper is organized as follows:(1)An overview of the related technologies required by the system.It mainly includes the introduction of Spring boot,which is a framework to simplify the development process of web projects,and the introduction of two databases,HBase and My SQL,which are used in this paper.(2)Demand analysis.Investigate the requirements of the public security department for vehicle tracking system construction and the specific content of the vehicle data captured by the camera,Mastered the demand background of vehicle tracking system based on bayonet data and the current storage mode of bayonet data.,so as to determine the business requirements of this system.Through UML modeling,using data flow diagram,case diagram and ER diagram to present the system concretely.(3)Design the network architecture and logic architecture of vehicle tracking system.The system uses Spring boot technology,adopts B/S architecture,and uses My SQL and HBase data to construct the database.The system is divided into three layers: front-end presentation layer,business logic layer and data persistence layer,which ensures the stability,security and high performance of the vehicle tracking system in this paper.At the same time,functional modules of the system have been determined,and each module has been designed in detail.In order to ensure the security of the vehicle tracking system,the system is uniformly deployed in the video private network of the Public Security Office.(4)Design specific data storage scheme of vehicle tracking system.Entities are identified from the data stored in My SQL and HBase databases,the relationships between entities and entities in each database are determined,and the ER diagrams of entity association relationship are given.In the HBase database,vehicle passing data is redundantly stored with different row keys in order to improve the retrieval performance under different retrieval conditions.In My SQL data,the table is designed and the structure of the table is explained.(5)The system is coded according to the designed scheme.According to the classes identified by each module,the module class diagram is drawn,and the core function points of each module are selected and explained in detail by drawing sequence diagrams.The vehicle tracking system is fully tested.Through functional and non-functional testing of the vehicle tracking system,the system can complete 27 functional requirements and concurrent volume response speed,which are sorted out in the requirement analysis stage,to meet the needs of users.
