Design and Implementation of a Remote Centralized Monitoring and Control System for Shipborne Satellite Communication
QIAN Xiaoyun,YE Yong,XU Jun (China Satellite Maritime Tracking and Control Department,Jiangyin 214400,China)Abstract :This paper analyzes the remote centralized monitoring and control requirements of shipborne satel﹣lite communication system,designs and implements a satellite communication remote centralized monitoring and control system.In order to solve the problems which come with the implementation of system such as many communication interface types,difference response time,model change and limited transmission band﹣width,some techniques are adopted,including serial switcher,double different thread queue,auto thread scheduling,model-view-presenter(MVP)design pattern,extensible markup language(XML),IP multicast and database increment synchronization.The application shows that the system operates steadily and reliably,and well implements remote centralized monitoring and control of satellite communication system.Key words :shipborne satellite communication;remote centralized monitoring and control;thread schedu﹣ling;MVP design pattern;IP multicast technology
