Abstract: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.
Keywords:rotary joint  interrupt programming  Serial interface programming
