基于惯性测量的天线副面位姿测量系统的设计
|
摘要
以新疆天文台奇台110 m大型射电望远镜建设项目为背景,研发了一套基于惯性测量原理应用于大型射电望远镜的副面位姿精确测量系统。系统基于惯性测量和嵌入式技术,分别设计了信号采集终端和上位机处理软件,解决了超大型射电天线工作中副面位置摆动较大而无法确定精确位置,进而无法基于副面上六杆并联机器人对副面进行精确调节以提高观测效率的问题。该测量系统是射电望远镜副反射面控制系统构建成为闭环控制系统的关键模块。副反射面控制系统构建成为闭环控制链路以后,可以极大地提高射电望远镜的整体观测效率。
The research has developed a measuring instrument system applied to the measurement of deputy reflection surface position and posture of the large radio telescope based on the QTT( Qatari Telescope).The system is based on the inertial measurement unit and embedded technology,the signal acquisition terminal and PC processing software are designed,the observation accuracy in large radio telescope is improved.The system is the core module in closed-loop control system of deputy reflection.The system can meet the requirements of the astronomical observation and deep space net.It is a pioneering work.
