Research And Design Of Monitor And Control System Of The Satellite Earth Station Based On The Technology Of Component

With the speedy development on satellite communications technology, especially with establishing the project of Manned Space flight in China, the satellite communications network in General Equipments Department is extending continuously and complicating increasingly. Acting as the core of the satellite communications network, the importance of the Network Management System is very clearly. Hence how to build an efficient, reliability and unified network management system for satellite communications net is a focused difficult hotspot problem now.COM/DCOM technology as a new component technique has already been used in all kinds of distributed service. Currently, it only limits simple application in net service based B/S, but it is not enough for this technique to support complicated application in real-time characterized C/S system, which will lower the adaptation of COM/DCOM technology in some computer control systems application field.This article, which based on the application of COM/DCOM technology and control system of satellite communication earth stations, studies two kinds earth station control system model currently: data center system and performance center system; and point out the short of them, and put forward a new model of the MCS, which has clear level, standardized interface, and is easy to be related and expanded.The task of this article mainly included:1. Studying the basic concept of satellite communication system and communication net control system, analyzing some of widely applied net administration model, and discussing specifically a design of net control system of satellite communications network.2. Studying the some theoretic of computer control systems , introducing the item development environment using COM/DCOM technology based on ATL, analyzing the realizing the control progress nowadays, and proposing a structure design of station control system based on the COM/DCOM technology.3. Based on the multithreading character of COM, and time limit and design demand of station control system which we researched, realizing the component program design, and describing specifically design on component program; designingon interface of component, and designing on synchronization of component.Based on the exploring on designing and realizing structure of station control system, this article will rise up the software qualify of station control system, widenapplication field of COM/DCOM technology in control system.
