The Design And Implementation Of Service And Management System Of Smart Science And Technology Museum

With the rapid development and application of mobile Internet technology,the application of mobile terminals is various,and the service and management system of Science and Technology Museum is also used in many mobile terminals systems.However,the existing mobile client function is relatively simple,and the service object is limited to Science and Technology Museum visitors.Therefore,we need to design a set of service and management for Science and Technology Museum,and realizes portable Science and Technology Museum mobile client for different users.In view of the deficiency of the existing mobile client technology,this thesis combines the current mobile terminal technology,and designs the service and management system of the smart science and technology museum.In this thesis,the following aspects of research work:Firstly,this thesis analyzes and summarizes the user needs of visitors and Science and Technology Museum managers for different users.On this basis,the thesis designs the application system model of the Science and Technology Museum Based on the C/S architecture,and designs the workflow sequence diagram according to the workflow of the system.The mobile client subsystem and terminal subsystem of the Science and Technology Museum are designed,and the functions of each subsystem are coded and tested.At the same time,it built the MySQL database which is associated with the server,and uses the SQL language to write the user information,exhibits information and other data tables.Secondly,through in-depth analysis of the Science and Technology Museum server system,and according to differences of the server processing service module,the server system is divided into Web server based on HTTP requests and instant communication server based on XMPP protocol requests.In the preparation stage of the server,this thesis studies the characteristics of the HTTP,XMPP network communication protocol,the working principle and the principle of the communication between the client and the server.On the basis of full preparation,designed the Web server model and business processing module of Web server in this thesis.At the same,LRU algorithm is improved to realize the caching policy at the server side and optimze the response performance of the server.And designed recommendation business module of exhibits in view of LRU in this thesis,and Java language programming and business.functions of it.Application program uses the Servlet technology,Java programming language to program the Web server's business function module,test and design the Web server interface document.At the same time,the OpenFire server based on XMPP request is built to deal with the request of instant communication function module.Thirdly,in view of the lack of mobile client function and the question of single user of existing Science and Technology Museum,this thesis designed a set of the user guide,exhibits display and voice navigation,instant communication,remote control and management of the administrator,weather and travel route query in one of the mobile client.In the design of instant communication function module,it is individually packaged,designed into SDK in view of the encapsulation idea of java,using the MVC architecture to build the SDK structure,and the SDK operation model of the timing diagram design and rendering.Finally,Java code is designed and implemented for code division design,related classes,interfaces and methods for instant message SDK.In the details of the display module,through the use of ShareSDK,the thesis design the function of the social sharing.In the exhibit voice navigation functions,this thesis quotes the open TTS source speech.playing system.The thesis programs the tool of speech initialization and playback.At the same time,in order to ensure the security of user login information,the user's personal data information to do MD5 irreversible encryption.In this thesis,the service and manager sysytem of the Science and Technology Museum has been coded,tested,and realized the various functional modules of server and client.With the increasing number of Science and Technology Museum,mobile client will have a broader application market and prospects.
