摘　　要：为了避免大天区多目标光纤光谱天文望远镜LAMOST光纤定位系统的定位单元在定位过程中发生碰撞,构造了一套基于AT89S51单片机的防碰撞系统。该系统实现了对光纤定位单元在寻星定位的过程中的运行状态进行实时检测,并将检测的结果反馈至控制主机,控制主机根据反馈的结果做出相应的决策。To avoid every fiber positioning unit of LAMOST fiber positioning system collision, a collision avoidance device based on AT89S51 single -chip was built, which can realize real - time inspection and control on the operation state of the fiber units when seeking for stars, and feed back the information of fiber units to the main control computer. The main control computer can make corresponding decision according to the state recognized results.
