摘要:Here design of electromagnetic spider webs imitating the actual spider web and trigram cropland structure, using the principle of bionics will combine Telluric Current, electricity, Atmospheric electronic, E-compass, 4G-GSM wave Switch, low and high frequency wireless transmitting and receiving devices. WIFI devices Switch. In theory, the electromagnetic spider webs induction method in Maxwell equation is adopted, and simple instruments and equipment are made by combining some software, such as wavelet transform, Mat-Lab simulation and configuration software. At ordinary times, all kinds of abnormal electromagnetic signals are detected at any time before the earthquake. In war, device can be used to detect all kinds of flying objects, such as stealth aircraft and cruise missiles, through the spider webs. Low equipment costs, reliable operation, we have forty years of wisdom crystallization [1].
