基于TDMA多目标遥测数据传输系统设计与实现

Design and Implementation of Multi Target Telemetry Data Transmission System Based on TDMA

摘要:

遥测监控是新机试飞提高试飞效率、保障试飞安全的重要手段,遥测数据的传输能力和传输质量决定了遥测实时监控性能的优劣；随着大量飞机同场次试飞任务的广泛开展,现有飞行试验单站点对应单目标的遥测体制存在一定的局限性,为了解决多个目标同时遥测数据传输的难题,文章在对常用的几种多目标体制进行了比较的基础上,设计了一套基于TDMA体制的多目标遥测数据传输系统,对该系统数据的传输速率、距离进行了理论计算,并进行了飞行试验验证,能够满足任务需求,有着很好的应用前景。

Abstract:

Telemetry monitoring is an important method to improve the efficiency of the new aircraft flight test, and to ensure the safety of flight test. The transmission capability and quality of the telemetry data determines the performance of the remote sensing monitoring. With a large number of aircraft in a flight test mission to carry out a wide range of performances, there are some limitations in the existing flight test single target telemetry system. In order to solve the problem of simultaneous telemetry data transmission, comparing of several common target system, this paper designs a system of multi - target telemetry data transmission system based on TDMA system. The data transmission rate and distance of the system are calculated.
