Design And Implementation Of Indoor Positioning Service System Based On WiFi

With the Mature of internet technology and the popularity of mobile Internet equipment,people are spending more and more time on mobile phone terminal.It becomes the majority way to surf on the Internet gradually that to obtain information and to send information by the intelligent terminal.In other words,the spring of mobile Internet is coming.The arrival of the mobile Internet has brought many changes in our life,work and learning.We became accustomed to the network environment slowly which is mobile,efficient and operationally available.The popularity of mobile Internet also provided technical conditions and environment foundation for the achievement of indoor location services.Through system design and programming technology,this paper is intended to achieve an indoor location service for intelligent terminal system based on WIFI terminal which is the neuron of mobile internet.This article was arranged and expounded from two aspects-the participation and the study of the author.First of all,Paper elaborated the design and implementation of positioning system service.This part relates to architecture and configuration of the classic JAVA WEB server framework,treatment and configuration of connection pool,handling of detail in system section programming,the allocation of communication model and interactive processing between the system and positioning application server also sensor.The architecture design of server system followed the architecture of Spring MVC,took Hibernate as the object data mapping scheme and interactive message through BlazeDS proxy and Flex front-end.No too much exposition was done on the applying of mature technology,instead of the system innovation and technology adaptation method.Then,the paper described the key problems and corresponding solutions encountered in the system design and implementation.It included the calibration and decision of map,playing back of tracking,anchor point capture in the location display,and the analysis and appfying in the display program and security zone.Each key points was analyzed and the specific idea was elaborated.The view of simulation method realization and the applying of specific system were also given in this paper.Finally,paper elaborated the design and implementation of positioning system module.The key functions of the modules are realized gradually by analyzing the relationship between entities of the module and implementing the function point.In the final section,the test analysis and corresponding test examples of server were given.
