站场无线通信在国外已有几十年的历史了,但它的发展比较缓慢。五十年代前,电子管设备体积大、笨重、耗电量大而限制了它在站场中的推广。六十年代初,半导体设备大量问世,站场作业人员(如车号员、调车员、铁鞋制动员、扳道员、列检员)广泛应用无线通信,使它获得很大发展。特别是近年来由于集成电路和大规模集成电路出现, Station wireless communications in foreign countries for decades of history, but its development is relatively slow. Before the fifties, tube equipment bulky, bulky, power consumption and limited its promotion in the station. In the early 1960s, a large number of semiconductor devices came into being. Widespread use of wireless communications by yard operators (such as vehicle drivers, shufflers, iron shoes, shift handlers, and inspector) made great progress. Especially in recent years due to the emergence of integrated circuits and large scale integrated circuits,
