通信卫星监控和数据采集系统初步研究

The Communication Satellite Supervisory Control and Data Acquisition Preliminary Research

通信卫星监控和数据采集系统（ＳＳＣＡＤＡ）专用于低数据速率卫星通信，可构成高性能价格比的大区域应用的专用卫星通信网。网络结构为星状网，远端数据采集与监控平台（ＤＣＳＰ）（即远端站）由一个全双工的星状网中的普通中心站控制。适于低成本解决传统的低数据速率卫星通信领域的难题，例如频率稳定性、相位噪声、抗干扰等。灵活的接口和协议选择为数据采集、远端监测、控制和交互应用等提供了高性能价格比的解决方案。通过模块设计可以进一部扩展网络功能。这就确保在适应网络功能需求和可用性的前提下最大限度的降低系统成本。它可应用于ＳＣＡＤＡ远端监控和数据采集、交互式数据通信、点到点及点到多点的数据通信等。

The communication Satellite Supervisory Control And Data Acquisition (SSCADA)network is dedicated to low data rate communication via satellite,and introduces private satellite communication networks as a cost effective solution for a wide area of applications.The Remote Terminals are controlled by one common Hub Station in a full duplex closed star network configuration.The unique design of the network introduces low cost solutions to traditional problem areas in low data rate satellite communication,such as frequency stability,phase noise,and interference requirements.Flexible interface and protocol options offer cost effective communication solutions for data collection,remote monitoring as well as control and transaction applications.The SSCADA network capacity may be extended in steps due to the modular design.This ensures availability of the required network capacity at minimum operational costs.The main market segments is SCADA(Supervisory Control And Data Acquisition),Transactional(Point of Sale and credit card authorization), General purpose Data Communication, Point to Point and Point to multiple point Data Communication.
