摘　　要：滑车运动信息采集系统使用有效的信息检测方法,精确地取得滑车在运动过程中的实时信息,为空间运动模拟平台提供了反馈数据。该系统以高性能的微控制器为核心,以CPLD相辅助,使用高精度光电编码器来协助微控制器精确采集滑车的速度信息;使用红外光电传感器对滑车的位置进行粗测,使用光电编码器对滑车的位置进行精测,将二者相结合取得了精确的位置信息;使用单片机内部的高精度定时器取得了当前的时间信息;使用ZigBee无线通信模块向微控制器发送来自滑车本身的触发信号。微控制器将上述数据整理后以特定的通信协议上传到主控计算机和控制单元,实现对滑车的状态分析和运动控制。空间运动模拟平台在教学和科研方面都具有很好的使用价值和实际意义。The pulley movement information collection system used effective detection method to collect real-time and precise information of pulley movement, providing feedback data for the space motion simulation platform. The system was based on high-performance microcontroller, and took CPLD as an auxiliary, used high-precision optical encoder to assist microcontroller in acquiring accurate speed of the pulley. Using infrared photoelectric sensor to roughly measure the location of the pulley and optical encoder to precisely measure the location of the pulley, precise location information was obtained with combination of both. This system used precision timer in the microcontroller to obtain the current time information and ZigBee wireless communication module to send the trigger signal from the pulley to microcontroller. Microcontroller sent the data to computer and control unit with the specific communication protocols. The computer and control unit analysed state of the pulley through the data to achieve control of the pulley. The space motion simulation platform has use value and practical significance in teaching and research.
