摘　　要：本文针对低纬子午环原方位传动系统中存在的振动问题 ,提出了新的解决方案 ,即采用振动较小的电机替代原电机。为此 ,我们对原单片机控制系统的硬件进行了扩展与修改 ,重新设计了单片机内的ASM控制程序。文中介绍了修改后的系统硬件结构与ASM控制程序。The original azimuth transmission mechanism in the LLMC causes too much vibration during the transpotation of the horizontal axis of the instrument.In order to solve the problem,a new plan is presented in this paper,which is to replace the original stepper motors with a new type of stepper motor.Therefore the hardware structure of the original control system must be modified.The hardware architecture of the new system is described.The ASM control program in the single chip microcontroller is rewritten,which is composed of 10 subroutines.The methods used in controlling motors and skills in designing the program are presented in the paper.

关 键 词：LLMC 方位控制 单片机 控制程序
