新一代遥测网络系统及其传输组网方式研究分析

Research on Telemetry Network System and Transmission Network

对新一代遥测网络系统(TmNS)进行了研究,对系统的组成框架结构进行了分析;新的遥测网络系统通过新增加远程、宽带数据链路部分,使得遥测网络系统具备了下行遥测传输能力,系统因此可以进行双向数据传输,而遥测网络数据的传输与控制需要在一定的约定规则下进行,对遥测网络系统的控制欲联网协议进行了分析研究,提出了关键的几项用于新一代遥测网络系统的控制与联网协议,为飞行试验遥测网络系统中试飞数据传输提供统一规则。

This paper discusses the new generation of telemetry network system, and analyses its physical structure. For the new apart ment of the remote and broadband data link, the system has downlink telemetry ability. The telemetry system therefore has the bidirectional data transmission ability. Transmission and control of network data needs to be under some certain rules. This article discusses the transmission and control rules, and presents several control and network protocol . And this article provides uniform rules for the flight test data transmission of telemetry network system.
