摘　　要：在车载式移动卫星天线座设计中,该文提出了在硬件上采用安全装置来取代传统的汇流环,保证了旋转设备与固定设备之间各种信号的顺利传递;利用计算机来处理限位中断,实现了天线座在方位面上连续旋转;并给出了硬件结构图及主要源程序。In the design of mobile-vehicular satellite antenna base,a kind of hardware safe device is used insead of the custom rotary joint ,so that the signals can be transmitted smoothly between fixture and rotary device.The limit interrupts are performed by the computer in order to keep the antenna turning continually in the azimuth plane.The hardware block diagram and a part of programs written in C are presented in the paper.

关 键 词：汇流环 中断编程 串行口编程
