Abstract

PURPOSE: To accomplish automatic detection of set points by means of an emergency receiver jointly used as a ground detection receiver eliminating elements on the ground and cars.
CONSTITUTION: An input signal is transmitted to a base station on the ground through a transmitting antenna 21 from a mobile station on a car in detection of the zone (receiving zone) of the base station set along the rail tracks. Here, an automatic channel scanning circuit 23 is provided to serve as an emergency receiver. Channels f1 - fe are scanned with an automatic channel scanning switch 22 and the electric field of the channels is discriminated with a field detector 24. Thus, the best channel is outputted to control circuits 15, 16 and 17.
