中文摘要:
      利用LabVIEW软件及采集设备研制了一套基于虚拟仪器技术的大望远镜中直线位移传感器测量系统。对大望远镜主镜位置测量中的直线位移传感器(LVDT)特性进行测量标定,获得直线位移传感器灵敏度、基本误差、线性度、重复性、往返回程误差,以便为下一步大望远镜主镜位置解算提供依据。测试结果表明,搭建的测试系统满足直线位移传感器测试需求,界面操作简单友好,直线位移传感器的精度指标达到位置解算要求,该测试系统具有一定通用性,也可用于测试其他直线位移传感器。
英文摘要:
      Using LabVIEW software and acquisition equipment, the position transducer (LVDT) measuring system on large telescope based on virtual instrument technique was developed. The position transducer on the large telescope was measured, the sensitivity, fundamental error, linearity, repeatability, reverse running error was obtained, in order to provide foundation for primary mirror position resolving of large telescope next. The result of test indicated that the measurement system satisfied the requirement of position transducer measurement, the interface is friendly, the accuracy of position transducer reached the requirement of position resolving, this measurement system had certain common ability, this system can be used in other position transducer.
