遥测网络系统发展与展望

遥测系统对于评定航空航天飞行器飞行试验结果、故障定位、健康监测和趋势预测等具有非常重要的意义。近二十年来，高码率遥测体制、双向通信及网络化遥测等需求不断增长，美国靶场司令委员会（RCC）下属机构靶场仪器组（IRIG）将遥测网络系统TmNS纳入到IRIG 106标准中，代表了下一代遥测系统的发展方向。在介绍TmNS发展历程的基础上，对TmNS的概念定义、典型架构、分层模型和网络数据消息、系统配置管理、时间同步、服务质量QoS、路由、源选择、安全等关键技术进行阐述和分析，结合我国遥测技术发展现状，总结其对我国遥测技术发展的启示，并对TmNS后续发展进行展望。

Development and prospect of the telemetry network system

The telemetry system is of great significance for evaluating the flight test results, fault positioning, health monitoring and trend prediction. In recent years, with the demand for high bit rate telemetry system, duplex communication and network telemetry constantly increasing, the TmNS was incorporated into the IRIG 106 standard by the Range Instrument Group IRIG, a subsidiary of the RCC, which represents the development direction of the next generation of telemetry systems. On the basis of introducing the development process of TmNS, the concept and definition of TmNS, typical architecture, hierarchical model and network-based data messages, system configuration management, time synchronization, Quality of Service(QoS), routing, source selection, security and other key technologies are elaborated and analyzed. Based on the development status of telemetry technology in China, the enlightenment of telemetry technology is summarized, and the development and prospect of TmNS is discussed.
