step one: the external signal is transmitted to the radio frequency signal identifier through the signal receiving line, and the radio frequency signal identifier acquires wireless signal data in the target area and transmits the wireless signal data to the wireless signal processing host;

step two: extracting signal characteristics related to target equipment from the acquired wireless signal data, wherein the signal characteristics comprise signal frequency, amplitude, phase, modulation mode, signal-to-noise ratio and the like;

step three: the wireless signal processing host classifies the extracted signal characteristics, classifies the signals of the same equipment into one type, establishes a corresponding signal library according to classification results, stores signal characteristic information of various equipment, and can be stored in a corresponding distinguishing disc;

step four: the wireless signal in the target area is monitored in real time, the acquired signal is matched with the information in the signal library, when the acquired signal is matched with the information in the signal library and the matching degree exceeds a certain threshold, the signal is judged to be the target equipment signal, the early warning is triggered, the early warning processor controls the buzzer alarm to send out an alarm through the early warning processor on one hand, and on the other hand, the wireless signal processing host controls the spring coil to be electrified, so that the connecting sheet moves upwards together with the signal receiving wire and is disconnected with the radio frequency signal identifier, the early warning device does not receive external signals at the moment, and further, the subsequent attack of the abnormal signal to the early warning device is prevented.
