| In recent years, network projector is more and more adored by the masses with itsunique advantages, while a remote controlling of device is also a trend. To achieve theremote control of a network projector, a management terminal, which is easy to use, fullyfunctional and with good performance would be very much in line with the requirementsof users. Therefore, a management terminal supporting the equipment has a good practicalsense.In this paper, the network projector is the background, Flex, which is very popularnowadays, is the primary development environment, and our purpose is to achieve alightweight management terminal based on C/S structure, which can be used to managethe device and users very easily.This paper describes some technologies associated with the network projectormanagement terminal at the very beginning, including network client, Flex and thedesktop projection mechanism based on VNC. Then it introduces some devices andsoftware that will be involved in the course of interaction, after being familiar with thesystem platforms and analyzing the terminal demands, we design the overall framework ofthe management terminal. The whole system is based on C/S architecture, which enablesthe management of devices, users and the desktop projection, and its interfaces is designedby using Flex, the data communication is finished by XML and immediatelycommunication is accomplished with JAVA, and the VNC based on Flex is used tocomplete the desktop preview, this terminal can be loaded and run by web browsers afterits completion. After detailed descriptions of key modules and implementation of them,we test and analyze the whole system completely. Test results show that the managementterminal achieves the pre-made features and has good performances, which is in line withour targets. Finally, it summarizes the entire text and has an outlook, also gives someimprovement measures to the problems, while pointing the future direction ofdevelopment. |
