【摘要】：利用磁悬浮技术和单片机技术相结合设计了模拟微重力环境的简易装置系统,该系统可实现对液体中"气包"位置的调控、显示跟踪其运动轨迹以及测量其大小等功能,主要包括运动控制、轨迹追踪以及测量分析三大模块。运动控制模块通过单片机控制机械滑台运动,调节电源电流、改变电磁力大小实现对"气包"运动悬浮控制;轨迹追踪模块和测量模块是由容器四壁各放置多个激光接收对管和收发模块构成,通过"气包"在运动过程中遮挡激光,引起配套的激光接收管电平变化,利用光电转换技术转化为"气包"运动的坐标值,从而实现"气包"位置的跟踪和直径的测量。本设计思路新颖,成本低廉,操作简单,为模拟微重力环境简易装置提供了一定实验设计思路。
[Abstract]:A simple device system for simulating microgravity environment is designed by combining magnetic levitation technology with single-chip microcomputer technology. The system can realize the functions of adjusting the position of "gas tank" in liquid, displaying and tracking its motion track and measuring its size, etc. It mainly includes three modules: motion control, track tracking and measurement and analysis. The motion control module controls the movement of the mechanical slider through the single chip microcomputer, adjusts the power current, and changes the electromagnetic force to realize the suspension control of the "air tank" motion. The track tracing module and the measuring module are composed of several laser receiver pairs and transceiver modules placed on each side of the container wall. The laser is shielded from the laser during the moving process by the "gas packet", which causes the level change of the matching laser receiver tube. The photoelectric conversion technique is used to convert the coordinate value of the "gas tank" motion, thus realizing the tracking of the "gas tank" position and the measurement of the diameter. The design idea is novel, the cost is low, and the operation is simple, which provides a certain experimental design idea for the simple device of simulating microgravity environment.
