警報システム。[Claim for Utility Model Registration] In a system consisting of a fixed station and a mobile station consisting of a transmitter/receiver having an identification signal generator and a detector, the fixed station and the mobile station each have a code generator that emits the same identification signal. Either the fixed station or the mobile station has a waveform shaping circuit and a modulation circuit for constantly transmitting an identification signal, and the other one receives the identification signal,
The receiving station includes a demodulation circuit and a discrimination circuit that detect and discriminate the identification signal, and the receiving station includes a discrimination circuit that detects the same identification signal as the identification signal and determines whether or not the identification signal reaches a predetermined detection level. and has an alarm generator that issues an alarm when the predetermined level is not reached, or an alarm signal transmitter that transmits an alarm signal with a larger output than the identification signal, and if it has an alarm signal transmitter, the alarm The separated alarm system is characterized in that the other one is provided with a receiver for receiving the signal.
