Abstract
PURPOSE: To make it possible to exercise a supervision over rainfall all the time by generating a signal when the rainfall exceeds a certain value and by transmitting the information while performing transmission in response to the inquiries from telephone subscribers.
CONSTITUTION: Signals from rain gauges 1, 1... provided along a road, track, etc., are led to signal transmitter 5 via cable 3 and then received as input signals. By those signals, signal transmitter 5 sends dial pulses for calling specific subscribers to subscriber's circuit 7 to call sequentially specific receiving telephone sets 11, 11... via originating telephone set 9 and when there is an answer, received information is sent out being converted into its corresponding voice. To signal transmitter 5, independent subscriber telephone set 13 is connected and general subscriber's telephone set 15 is separately provided.
