Research And Design Of Mobile Target Positioning Service System Based On Android

The rise of mobile Internet has driven the rapid development of mobile terminals.Using mobile terminal services to plan daily life has become a trend.People can quickly achieve travel path planning through mobile terminals,However,in the existing electronic map,the path planning results of multi-target points are often affected by the order of nodes,and at the same time,it is unable to meet the user's multiple considerations of travel planning in the case of multi target points.The thesis topic is based on the LBS,using the Android system as a development platform and carrying Baidu map API design,and implements a location service system for a mobile target.The main research contents and achievements of this thesis are as follows:1.Operating system framework and key technologies research.This thesis analyzes the framework of the Android system and the basic application components of the system,and it deeply studies the positioning model of the system and data storage technology of Android system and other technology.2.Study on multi-target points path planning.For the multi-objective path planning problem,first,the points are stored in the set,and the cost matrix is preprocessed by using the function model,and then add the necessary pruning conditions.On this basis,the result of path planning can be obtained quickly by using enumeration strategy.At the same time,the idea of linear weighting is adopted for multiple expect of users,and it is converted to a single path planning problem,which is more convenient for user travel planning.3.Research on system function design.The system consists of a mobile and a server.The design of the mobile terminal is realized.The mobile mainly has basic map functions,geofence warning,multiple target points path planning,data storage and other functions.On the server,Apache Tomcat 7.0 is used as the server.In this thesis,the MySql database is used to store data in real time,and real-time monitoring of user trajectory data is realized on the Web side.4.Realizing the system on the basis of design,and completing the test,which verifies the feasibility of algorithm optimization and the practicality of linear weighted thinking in practical path planning.At the same time,the track storage module extracts data and uses DBSCAN clustering analysis to yields a set of interest points of sample data.And It has a great help for data mining.The thesis based on the realization of the basic map service function,the solution to the existing problems in the existing electronic map path planning is given.Meanwhile,the system has designed a user data storage module and a user area early warning module,which have played an important role in the mining and monitoring of user trajectory data.
