Abstract
PURPOSE: To increase information reliability in a speed limit selector device that uses a parallel dual system receiver by suppressing, when two systems give signal detection outputs in any channel, the signal output of one system of other channel.
CONSTITUTION: When both of two detection circuits V1RA and V1RB of the first channel detect an ATC signal received through the antenna on a vehicle and give off signal detection outputs, the input voltage is applied to the base of transistor Tr1 of the first AND circuit, the transistor becomes ON, and receiving relay V1R is operated by the output from first detection circuit V1RA. At the time, the output of first AND circuit 1, i.e., the emitter voltage of Tr1, makes Tr2 of NOR circuit 5 ON and relay R is operated. By this, second AND circuit 2 is opened and the output of first OR circuit is not applied to receiver relay V1R. Thus, fail-safe reliability is increased.
