The Research And Design Of Portable Satellite Communication Earth Station Multi-terminal Monitoring System

A multi-terminal monitoring system of portable satelite communication earth station based on embedded web server and B/S architecture is studied in the thesis.And the multi-terminal monitoring system can monitor the working status of the equipment conveniently and intuitively.Furthermore,it can apply to PC,iPad,or mobile phone,and they can match very well correspondingly.This thesis introduces system framework and hardware modules of the portable earth station,and achieves the transplantation of the embedded Linux operating system,web server and SQLite3 database into ARM9 series microprocessor in order to build the network development environment of a multi-terminal monitoring system.Meanwhile,the system adds a wireless network module in ARM board that can transplant wireless network card driver.Therefore,the terminal devices such as mobile phone or iPad can access to the system by using wireless WiFi technology.The MVC design pattern is used in system development,and the code of browser-side and server-side is implemented by using HTML+CSS,JavaScript,Ajax,CGI,message queue,SQLite and other technologies.In the browser side,the responsive layout of multi-terminal which can be realized by percentage,media query and Bootstrap is used in web designThe experiment results show that the monitoring system has reached the expected design requirements in terms of website stability,security and compatibility.Besides the system successfully realized the data interaction between the user and the portable satel ite antenna,so the user can monitor the real-time status of the satellite,which brought great convenience to users.
