Abstract

PURPOSE:To enable transfer of needed information as well as an interruption of emergency communication from a subordinate station, by allowing the subordinate station to perform blocking release by itself automatically after a certain time in a selective signal system. CONSTITUTION:Between master station 1 and subordinate stations 2-N, mutual communication comes into effect at frequency f1. In this case, a selective signal sent out from master station 1 is input to deciding circuit 12 of each subordinate station and when the selective signal of the station is decided, latch circuit 14 is driven by output Y. Then, a ready-for-communication state is displayed 16 and radio transmitter controller 18 is driven by operating press button 17, so that transmission will be possible. On the other hand, when the selective signal is not addressed to the station, display unit 16 displays the ready-for-communication state by output N and gate 15 is turned OFF. Further, clock 22 is counted 20 by output N and circuit 14 is driven by an output of a fixed count value to turn gate 15 ON.
