Design And Implementation Of The 3D Drawing And Display Module Supporting Service Composition

For the past few years,more and more applications and services need to interact with information with real world.Therefore,more enterprises have adopted this new-generation information technique marked with the Internet of Things(IoT).With the increase of users of IoT,the existing system could not totally satisfy various requirements of users.For example,common supervisory and configuration systems just provide 2D view to users,but they would like to get 3D view which is more vivid.Then,the services of common supervisory and configuration systems are independent to each other.If we combine several services by standard operations,then it could generate a new service for a specific program.At the same time,users always need to get a client of this software and set corresponding configurations before acquiring the view from common systems.However,some users just need to supervise the view parts instead of all the functions of this software.Thus,common supervisory and configuration systems have some limitations.In response to the laboratory projects,we design a supervision and configuration system which supports service combination.The system provides the design and operation features of both 2D and 3D visualization and convenient network supervision and control features and diverse service for different requirements of display.Drawing module and display module are two main modules of this system.Drawing module makes some functional extensions on the basis of Jgraphx and SweetHome 3D that are open-source software.According to W3C Widgets standards,display module packages Widget to serve users.Our system satisfies various requirements of different industries and different users.The drawing module of our system provides the function of supervisory control and configuration based on service composition.In order to offer interface to the display module,staffs who design engineering equipments could draw 2D SVG model figures and 3D OBJ model figures in the drawing module.The display module is based on B/S framework and its service-composition platform provides staffs who test engineering equipments the monitoring function which not only displays real-time dynamic pictures but also real-time data gained from sensors.Moreover,authorized staffs could control components in some ways which contain the single remote control,the timer remote control and the remote control of a set.We carried out thorough tests to our system and verified the function of every module.In the end of this thesis,we conclucde our current work and point out the existing shortcomings.
