以我国自行研制的磁悬挂天平系统为背景,主要研究了利用线阵CCD传感器构建MSBS的模型位置与姿态测量系统以及相应的传感器配置方案、信号转换、测量原理和测量流程等问题。该系统的位置与姿态测量系统以两组共5片线阵CCD作为MSBS中悬浮模型的5自由度位置与姿态传感器,以串联的多级惯性环节电路为脉宽-电压转换电路,将测量信号分别输入控制回路和校准测量回路。文中详细介绍了5片CCD传感器的配置方案及其测量原理,然后研究了使用多级惯性环节实现脉宽-电压信号的转换问题,并对该方案进行了理论分析和仿真,最后研究了利用CCD的测量信号反演悬浮模型位置与姿态的数学原理及其自动测量流程。

Based on the magnetic suspension and balance system (MSBS), this paper mainly studies the problem of designing the position and attitude measurement subsystem of MSBS by CCD array sensors, and other relevant problems including sensors configuration, signal transformation, auto-measurement principle and flow. 5 CCD array sensors divided into two groups are used to measure the 5-degree freedom position and attitude of the model suspending in MSBS, and the multilevel inertial element circuits connected in series are used to transform the pulse width signal into voltage level signal. The position and attitude measurement subsystem of MSBS inputs its measurement signal to control loop and calibration & measurement loop of MSBS respectively. This paper introduces the configuration of 5 CCD array sensors and its measurement principle in detail. Then, the problem of the signal transformation using the multilevel inertial element circuits is discussed, and the theoretical analysis and simulation are presented. Finally, the mathematic principle and auto-measuring flow of achieving the position and attitude of the model suspending in MSBS by CCD array output signal are discussed.
