Design Of Police Motorcycle Management System Based On B/S Architecture

In order to optimize the management of the police motorcycle for the unit,and facilitate the reasonable allocation of vehicles and assignment of tasks to policemen,vehicle management system is particularly important for police officers' attendance in public security organs.Using the large information storage space and the processing ability of high performance of computer,the system can classify and record the vehicle basic information in detail,such as the coordinate position of the motorcycle,vehicle usage,the fault condition,etc.Users can directly monitor the change of vehicle information in the system,and timely handle the emergency situation encountered in the vehicle operation.The real-time monitoring and management platform for police motorcycle based on B/S architecture is designed for dealing with the problem of high concurrency of data,reducing memory overhead and improving response efficiency in communication.In addition,it also needs to support visualization display,and optimize dispatching route design.This paper is a model of three-tier structure,including on-board equipment,server,and browser.Netty framework is adopted in the communication part between server and vehicle equipment to deal with the problem of blocking communication,which solves the problem of low efficiency that a request occupies a thread.The design pattern in this paper is the responsibility chain design pattern,which is the pipeline pattern in Netty framework.Make it easy for the system to handle subtasks in single thread mode.This paper explores the disconnection and reconnection function of the heartbeat mechanism of the framework and apply it to the design of transaction judgment processing.Real-time video surveillance module uses RTMP-based streaming server to encapsulate and decode YUV format video captured by vehicle equipment camera into H.264 format,and push it to front-end flow player to realize live broadcast.This paper designs the level of database tables in detail.What's more,it realizes the close connection from concept to logic,and ensures the efficiency of the system.The overall structure design of the system mainly includes five functional modules:daily monitoring module,vehicle scheduling module,information maintenance module,fault maintenance module and attendance information module.After that,the functional testing and pressure testing are carried out on all modules of the system,and the performance and accuracy of the system are analyzed.The stability of data communication is guaranteed by the TCP underlying communication model based on Netty framework.Finally,the system has better reliability and smooth operation under frequently data communication.
