Research And Implementation Of Location Monitoring Management System Based On Django

As we all know,with the continuous innovation of science and technology,the continuous development of mobile Internet and the rapid spread of mobile devices,geographic location services have become more and more diversified and intelligent.Through the location service,people can pass a variety of information.Now,geo-location services have a strong interactivity,geography services are also used in many special areas or special groups,according to the special needs can achieve special features.For primary and secondary students wearing a GPS positioning function of the bracelet,through the system to monitor the location,so as to protect the safety of students play a role.The system includes mobile APP,server and hand ring hardware.This article mainly studies and implements the server side,in the server side using Django technology for system development.My Cat is a database middleware,which can be used to support the My SQL database used by the system,it can be more convenient to build a database cluster.To ensure a stable connection between the bracelet and the server,use Netty technology to quickly develop high-performance,high-reliability web servers.The system of research and implementation process is as follows:(1)Requirements analysis stage: the use of UML technology on the functional requirements and non-functional requirements for a detailed analysis.(2)Design stage: The function modules of the system are designed in detail,including real-time positioning,path monitoring,electronic fence,historical trajectory,graphic management,batch real-time positioning,batch sending messages and other functions.Due to weather factors,the location of the city's tall buildings,the geometric distribution of the satellite and so on,GPS positioning function in the city there is a big error,so in the historical trajectory function module using Kalman filter algorithm.And through the algorithm to improve,thereby reducing the positioning of the error generated in order to obtain a better user experience.(3)Implementation stage: the use of Python,HTML5,Java Script language coding of the system work.(4)Test stage: the use of black box testing and white-box testing combined with the way the system tested,the use of a large number of test cases to ensure that the system can be safe and reliable operation.
