The Research And Implementation Of Smart Campus Client Based On Android

With the rapid development of the technology, the intelligent mobile phones are related to almost every corner of our life. They have been one kind of the widely used tools for us to learn, to make friends or entertainment. The number of the intelligent mobile phones has overpass that of the personal computers. Because of the operation system(OS) Android can be freely accessed and it’s an open source OS, it has been the most popular OS for the intelligent mobile phones currently. As to the scale of the marketing and the large size of the users, developing the software based on the Android OS has a better future.The WI-FI, a kind of the accessing interface for the internet, has been involved in many places in our life. You can connect to the WI-FI nearly everywhere such as the supermarkets,the coffee bars, the schools, the libraries and so on. The wide-spread distribution of the WI-FI devices makes the location technology extended to a lot of service scenes. Then, the requirement of the WI-FI location technology improves at the same time. Thus, studying the WI-FI location technology is of significant.In this article, we introduced the current popular indoor location technologies including the direction based and the RSSI based. The detail of the loss model of the signal transporting and the related algorithms were illustrated. An algorithm based on the multi-location which can improve the accuracy of the location was introduced. Simultaneously, those popular intelligent OS were presented and analyzed. This article also analyzed the exploring technologies that related to android such as the data storing, the annotation of the net-programming including the xml annotation and json annotation, the mechanism of the information processing, the self-defined widget and so on. After finishing the accumulation of the technology and the environment construction, the situation of the informatization of the schools and the real requirements of the home-school associations were studied. The intelligent platform for the schools was constructed finally after the model construction and the detailed analysis of the intelligent school with the UML use case and use case description.This platform is oriented to those primary schools and middle schools which is a communication platform of the teachers, students and their parents. The users were classified into student points and teacher points. Different users can obtain the different services. The functional modules include the teaching, studying and servicing and so on. At the same time,the integration of the WI-FI location technology and the information pushing can adopt WI-FI location technology to the intelligent school platform in fact. Some requirements werementioned during the UI designing process which can avoid the leakage of the RAM, which can make the running of the phone more fluent. During the testing section, complete testing with different version of the virtual machine and a series of real Android mobile phones for the logical function and UI interface were conducted. The results were satisfactory, the information pushing based on accurate location with WI-FI can work well.
