Abstract

PURPOSE:To detect the abnormality of a radio transmitter on the receiver side by adding a periodical reporting function which automatically radiates a radio wave to the radio transmitter at every interval of a fixed time. CONSTITUTION:When a push button A of a radio transmitter 101a id depressed, this information is modulated by a modulating part D and a radio wave is radiated from an antenna E. Unless the button A is depressed, pulses from a timer B are counted by a control part C, and information of no depression is modulated by the modulating part D and the radio wave is radiated from the antenna E when the counted value reaches a certain value. Meanwhile, the radio wave radiated from the antenna E is received by an antenna F of a radio receiver 102a and is demodulated by a demodulating part G, and its contents are displayed on a display part I. Since the radio wave is not transmitted from the transmitter 101a every interval of the fixed time if abnormality occurs in the transmitter 101a, the display part I is monitored to detect the abnormality of the transmitter 101a.
