| 摘 要： | 观测控制系统是为LAMOST(大天区面积多目标光纤光谱天文望远镜)开发的基于网络的、自动运行观测流程的软件系统。在研究观测控制系统的实际网络拓扑结构和通信协议的基础上,利用网络模拟软件NS2对其进行模拟和分析,并对网络性能进行了实测。网络模拟和实测的结果证明,目前开发的观测控制系统在现有的网络结构和通信协议下能够稳定工作。同时,本研究也为观测控制系统的网络故障诊断提供了方法。

| Abstract: | The Observatory Control System(OCS)is a software system for the LAMOST(Large Sky Area Multi-Object Fiber Spectroscopic Survey Telescope).It is network-based and can carry out an operational procedure of observation automatically.The actual network topology and communication protocols of OCS are studied in this paper,and a simulation software NS2 is consequently used to simulate and analyze the network.Comparison of simulation results and actual measurements shows that the NS2 simulations are useful in analy... |
