Research And Design Of Vehicle Monitoring System Based On Android Platform

In recent years,with the rapid development of the national economy,people’s living standards are constantly moving towards a better off level.The number of car grows explosively.Some enterprises and individuals need to know more about the vehicle’s real-time situation and location information.Therefore,the vehicle monitoring system is particularly important.At present,most of the traditional monitoring systems adopt B/S(Browser/Server)mode.This requires the vehicle management personnel and users to monitor and manage vehicle in front of the monitoring terminal,and people can not be timely view the vehicle information and understand the operation of the vehicle in a dynamic environment.Thus,it can not provide a powerful information support for the real-time management and monitoring of vehicles.In addition.The system also has a high cost of development and a very low convenience.The use of small and medium enterprises and individuals are not cost-effective.In order to solve the above problems,this article has studied deeply and widely from the development status,application prospect and technical feasibility of vehicle monitoring system at home and abroad.A new intelligent mobile phone used in vehicle monitoring system is proposed.The system is based on C/S(Client/Server)architecture,combined with Android,GPS,wireless communication,data storage and processing,multi thread,Baidu Map and other technologies.Hardware parts adopt GPS module and SIM5320 E module and software components use the Java programming language,My SQL database technology and Apache’s Tomcat light weight servers as a Web server.Through the study of the secondary development of Baidu Map in the Eclipse development tool,this paper implements the function of real time management and monitoring for the vehicle in dynamic environment.The whole system is divided into three parts: vehicle terminal,monitoring terminal and network service part.Among them,using a variety of technology integration method and based on the Java language and My SQL database development,the vehicle terminal implements GPS serial communication,data analysis,storage,multi-level processing,wireless transmission and otherfunctions.In addition,in order to improve the positioning accuracy of GPS,this paper proposes an integrated map matching algorithm based on dead reckoning,projection and fuzzy logic evaluation.Some simulation results and examples are given to prove the validity and feasibility of the algorithm.Based on the design pattern of MVC+DAO,the network service part uses some technologies,such as JDBC,Servlet,HTTP,JSP and so on.It implements the data real-time interactive function,which provides the interface function for the Android client.Based on the Android’s design basic and Baidu Map’s secondary development technology,the monitoring terminal has completed two parts,namely,the layout and function design of the Android client interface.It can well satisfy the function of human-computer interaction.The vehicle monitoring system will not only be able to visually and real-time dynamic display on the high precision map for the location and trajectory of the vehicle,but also to achieve a query,manage,and update important information on the notification bar modules.This system makes vehicle’s managers and users can understand the vehicle’s running status anytime and anywhere.It provides the decision-making and support for the management and scheduling of vehicles.At the same time,it also improves the convenience and real-time of the system,which has a wide range of application prospects.
