Research And Design Of Intelligent Gun Management System

Gun management is vital to maintain social security,reducing gun violence incidents,and ensuring the safety of citizens’ lives and property.Aiming at problems such as the relatively traditional management methods in the gun management of a financial escort company,and the fact that guns leave the warehouse and become information islands,this thesis proposes an intelligent gun management system to realize intelligent management of gun information and real-time monitoring of gun locations.As a carrier,the communication and sensing terminal of the company has carried out system requirement analysis and architecture design,studied the core positioning algorithm,completed the design and development of core functions such as data collection,calculation processing,and network transmission based on the terminal,and built an intelligent gun management system Embedded hardware and software and upper computer software platform and completed the test verification.The main work of the thesis is as follows:1.Researched and analyzed the specific application scenarios of guns in the financial escort industry,put forward specific solutions for different scenarios of gun management,designed the overall scheme of intelligent gun management system,embedded gun terminal software and hardware scheme and host computer software scheme,realized The informationization of gun warehouse management and the visualization of gun positions during the escort process have improved the efficiency and safety of gun management.In the warehouse management,the Win Forms platform is used to complete the software development of the upper computer based on the My SQL database,and the humancomputer interaction interface of the upper computer of the intelligent gun management system is designed.Combined with HF RFID and UHF RFID tags,the automatic registration of guns in and out of the warehouse and the inventory information of the gun warehouse are realized.In the process of escorting,the combination of GPS/Beidou,IMU,and UHF RFID positioning methods is used to realize real-time positioning of guns in a wider range of scenarios.2.In order to carry out the real-time positioning of the gun in the whole process,a comprehensive positioning system based on heterogeneous multi-source sensors is designed and implemented.This include the inertial navigation algorithm based on the accelerometer and gyroscope components,the loosely combined integrated navigation algorithm based on the extended Kalman filter,and the angle of arrival(AOA)positioning method based on the phase difference measurement technology.In order to realize the application of the above three positioning algorithms in engineering,a seamless switching positioning system based on threshold and GPS positioning accuracy is comprehensively designed to ensure the continuity and reliability of positioning.3.Build an application testing platform,and conduct functional tests on the host computer software and the gun positioning unit for the two application scenarios of the warehouse and the escort.The software function test of the upper computer shows the functions of gun inventory,identification and registration of gun output and storage,chart retrieval,visual location viewing and other functions.In order to verify the performance of the positioning algorithm in practical applications,an inertial and integrated navigation experiment platform based on real vehicle driving and an RFID positioning platform at the entrance of the bank were simulated and built.The test results show that the positioning error of the inertial navigation system within 10 s is less than 1 m,the error of the integrated navigation system fluctuates in the range of-2 m to 2 m,and the average error of the RFID positioning system is 0.8 m.The intelligent gun management system researched and designed in this thesis has the characteristics of multi-sensor integration and multi-scenario application,which provides a reference for the application of the Internet of Things,RFID technology,and positioning algorithms in the gun management system.
