嵌入式系统在气浮转台无线测控实验中的应用

以卫星气浮转台实验为背景,介绍了基于实时嵌入式系统的气浮转台无线测控通信子系统的设计。利用VxWorks操作系统实时性强、多任务调度的特点,对转台上的串口数据采集、转台上下的无线网络通信进行了任务化编程。在线测试表明,嵌入式实时操作系统VxWorks可以合理而快速地对各任务进行实时而可靠的管理和调度,嵌入式系统可以出色地完成转台无线测控通信任务。

Application of embedded system in wireless TT&C experiment with air-bearing turntable

At the background of the experiment of satellite air-bearing turntable,the design of wireless TT&C sub-system based on realtime embedded system is introduced in this paper. Using the characters of real-time and multi-task of VxWorks OS, tasks of serial data collection and wireless LAN communication between turntable and main-control computer on the ground are modularized. The On-line test indicts that VxWorks OS can manage and control every realtime task quickly and credibly, and embedded system behaves well in wireless TT&C task.
