摘　　要：调度总机主机与调度台之间传统的通信方式为RS-232接口,虽然是全双工模式,但存在着数据传输速率低、抗干扰性能差的问题。采用射频同轴电缆作为主机与调度台之间的联系线缆,不但使传输速率得以大—)大提高,抗干扰能力也大大增强,同时还可复用同轴电缆实现调度台的直流供电。Connecting master station and dispatching terminals by RF coaxial cable can not only improve transmission rate, but also enhance anti-jamming performance. In addition, the coaxial cable can also be used to provide DC power supply for dispatching terminal. This paper introduces the ways how to realize the communication between master station and dispatching terminals by using RF coaxial cable.
