PURPOSE: An emergency signal transceiving apparatus of an anti-crime/disaster-prevention system is provided to grasp an emergency quickly. CONSTITUTION: A cable sensor(10) senses an emergency due to anti-crime/disaster-prevention. An emergency signal processing unit(20) transmits the emergency signal to a remote site by comprising an emergency signal input stage(21), an emergency signal processing stage(22), a DB(23) and a communication unit(24). The emergency signal input stage receives an emergency signal transmitted from the cable sensor. The emergency signal processing stage processes the emergency signal by using the FFT(Fast Fourier Transform) and DSP(Digital Signal Processor) analysis method. |
