Application of Network Communication Technology in Measurement and Control System of Supersonic Combustion Tunnel

摘要:

燃气流超声速风洞测控系统主要由总控指挥调度系统、各测控分系统、数据库系统等组成,为了实现试验过程中各系统之间的大量数据交互,本文运用了端到端网络流数据传输技术、网络共享变量技术、OPC技术、NTP网络授时技术等一系列网络通信技术,实现了风洞系统的分布式运行控制及数据实时存储、数据集中显示、数据集中管理、多系统数据对时同步等功能,提高了数据传输的效率与可靠性,并且已经应用到风洞试验中,达到了预期效果。

Abstract:

The measurement and control system of supersonic combustion tunnel is composed of master control system, measurement and control subsystems and database system. NI-P2P、Shared Variable、OPC and NTP network communication technique is used in this paper, to achieve a large amount of data interaction between different systems in the experiment. This paper realizes the distributed control、data real-time storage and centralized display and multi system data synchronization and other functions, improves the efficiency and reliability of data transmission. These techniques have been successfully applied to wind tunnel experiments, and achieved the desired results.
