Design And Implementation Of Personnel Movement Trajectory Tracking System

Personnel movement trajectory tracking system is a security field project developed by my internship company.It is mainly used in the national judicial system,public security system,prison system,criminal investigation system and other fields.With the proposal of "Intelligent Police" and "Green City" in recent years,the key personnel movement trajectory system emerged under the environment of the ministry of public security,which emphasized "strengthening police through science and technology" for many times.The paper designed and implemented the personnel movement trajectory tracking system,which provides business support for key units.The system as the company's video intelligent platform subsystem has completed the first phase of design and put into practical application at present.Discussing the integration of existing video monitoring equipment and business system,and establishing a unified target monitoring,tracking and trajectory description analysis system by using advanced technical means such as deep learning.It helps analysts quickly realize multi-dimensional screening,focus on key clues,realizes efficient information mining,and describe and present the correlation between data objects in a graphical way through data processing,storage management,data filtering,visual interactive analysis and other technologies.IntelliJ IDEA is used for client and server interface design.The client uses AngularJS,D3.js and other technologies to present the interface by Google browser webpage.The server is developed based on JDK1.8 and Spring Boot.Nginx reverse proxy technology is used to solve cross-domain problems and front-end data communication problems.MySQL database is adopted for persistent storage of data,and Ehcache lightweight caching mechanism is combined to improve system performance.I participated in the design and development of the system's four modules,namely,personnel tracking module,area regional module,personnel management module and data configuration module,among which the data configuration module includes five sub-modules,including trace configuration.The software architecture and code design are reasonable,the structure is stable and the extension is supported.It development idea is well satisfied.The internal test stage runs stably,and the online version runs well.
