摘要
给出一种使用公用电话网进行远程控制雷达机房附属设施的系统。该系统采用普通双音多频电话机上的按键,作为控制命令按键,通过MT8870双音调多频接收机作电话双音多频解码核心,实现对雷达机房附属设施远程控制功能。
A sort of long-range-controlled system used in Doppler radar machine room on the communal telephone network is specially presented and further discussed in the paper,which adopts commonly-used keys on the two-sound-and-several-frequency telephone sets as key presses for inputting controlling orders and finally makes come true the long-range-controlled functions of the affiliated facilities in the radar machine room by taking the MT8870 two-sound-and-several-frequency receiver on telephone as the decoded core.
