Design Of Remote Service System For Portable Satellite Earth Station

This system studies the portable communication satellite earth station,and uses the remote service technology to assist it to complete the better application.In this paper,we study the portable communication satellite earth station,and use the remote service technology to help them achieve better application.This paper briefly introduces the development status and prospect of portable satellite communication earth station at home and abroad,analyzes the antenna control system of earth station,and studies the design and implementation of the remote service system of portable satellite communication earth station.The system is based on B/S architecture.It respectively introduces realization process of the user interface layer,logical processing layer and data layer,and determines the satellite communication protocol.It uses the RS-232 serial communication interface to communicate between wireless module and lower computer,and configure serial port parameters.The satellite modem communication protocol is based on frame transmission mode.Followed by the focus of the analysis of the key technologies in the system,such as CGI,Ajax technology,inter process communication technology,multi threading and JDBC connection database.It completes the software development of remote service system for portable satellite earth station.Finally,the results of the software interface are given,the interface function is analyzed,and good results are obtained.After logging into this overall system,the operator can view the operational status of the portable earth station by means of the interface and control the earth station by setting parameters.Remote service software,including earth station detection,database management,remote exchange of circulation,to help correct the error and other functions.When the earth station fails,and the operator cannot solve,you can click on the main menu of help,the system will enter the service module.
