Title:
NOISE DETECTION ANALYZER FOR ELECTROMAGNETIC WAVE
Document Type and Number:
Japanese Patent JP3188609
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To perform a prediction analysis of earthquake generation by using analytical data of noise detected from high frequency electromagnetic wave.
SOLUTION: Each detection device 1a to 1c is arranged in different area so as to receive AM radio wave, for example, so that vocal information carried by the high frequency is canceled and the output levels become constant regardless of the inclusion of vocal information. When noise at a high frequency is received in this state, the received information of the noise is sent to an analyzer 2 together with the received time. The analyzer 2 compares and judges the noise signal and the time signal from each analyzer 1a to 1c as a sign and the like of earthquake occurrence, for example, with a logic specified in advance, and then informs each member A to X of the evaluated result by way of a communication means 5 when the judged result corresponds to a reference determined in advance.
