Intelligent earthquake safety machine for household purpose

Abstract

This invention relates to an intelligent seismic safety machine for household use, which comprises a sensor circuit powered by switching mode stable voltage source including jar testing probe, voice testing probe; a data processing circuit including a jar signal comparing amplifier, a voice signal comparing amplifier; and an alarming circuit linked to output port of microprocessor composed by electric linking combinational logic state processor, jar signal comparing amplifier, a voice signal comparing amplifier. Using this safety machine can avoid danger earlier by alarming signal.

Description

technical field [0001] The invention relates to an earthquake alarm, more specifically a household intelligent earthquake safety machine. Background technique [0002] Earthquakes are natural disasters that are difficult for human beings to resist. They seriously threaten the safety of human life and property. There are about 1,000 destructive earthquakes with a magnitude of 5 or above, and more than a dozen strong earthquakes with a magnitude of 7 or above. At present, the prediction and prediction of earthquakes in the world is still in the exploratory stage, and the natural laws of earthquake breeding and occurrence have not yet been fully grasped. Therefore, the current method of earthquake prediction and release in my country is: set Seismic detection stations, each seismic detection station is surrounded by multiple observation points, using special instruments and equipment to collect on-site data such as geomagnetism, geomagnetic field, geostress, ground water level, ...
