Simple Space Electric Field and Earth Magnetic Anomaly Remote Alarm System

Before the earthquake, the earth abnormal phenomenon electromagnetic field already by many domestic and foreign examples confirm the observation, placing multiple groups of magnetic anomaly and special wireless transmission module in the earthquake prone area (frequency by 30Mhz (distance) 30 meters), and the lengthening device (frequency by 315Mhz) (about distance 1000 meters), can be in a fairly wide range induction to the earth the abnormal variation of the electromagnetic field, use off the shelf GSM switchgear can respectively signal received at the receiving host, long distance transnational forecasting electromagnetic anomaly, we design the electromagnetic spider web a charge in electromagnetic anomaly alarm 200 times above, the field placement device normally used for more than one year, not only convenient to judge the earth abnormal electromagnetic field, but also to the remote alarm, intelligent synchronous, usually in a few days before the earthquake the seismic electromagnetic anomaly observed alarm in time, is the more advanced a plurality of electric magnetic spider network can also be analyzed the quake epicenter. And the device has the advantages of low cost, low power consumption placed outdoor equipment, is a promising method for popularization of short impending earthquake prediction.
