Problems solved by technology

[0004] Through the analysis, it can be seen that the shaking of the ground is not obvious in the first few seconds to tens of seconds of the earthquake. If people learn about the earthquake information and evacuate quickly, there is a great hope of survival, but in many cases people often do not respond in time until the ground shakes. When the shaking is severe, it is felt as an earthquake, but the hope of escape is often very small at this time, especially when people are sl

Abstract

The invention discloses a self-made household earthquake alarming device. The device is composed of a longitudinal wave detecting circuit, a transverse wave detecting circuit, an illumination circuitand a sound alarming circuit, the judgement of early earthquakes is conducted through the detection on a horizontal plane, when an earthquake takes place, longitudinal waves firstly arrive on the ground to allow the ground to generate corrugated lifting and lowering, a ground lifting and lowering signal is detected by the longitudinal wave detecting circuit, kermesinus light is sent by a light bulb LD, a siren sound is sent by an integration circuit IC4 to remind people to rapidly evacuate, when transverse waves arrive on the ground, the ground is shaken left and right, a left and right swinging signal is detected by the transverse detecting circuit, the light bulb LD is changed into normal light color from kermesinus to provide convenience for people to evacuate, and the siren sound sentby a loud speaker SW is louder to remind more people to rapidly evacuate. The alarming device has the advantages that the structure is simple, the alarming effect is significant, and the alarming device is particularly suitable for the use at night.

Description

Technical field [0001] The invention relates to an alarm device, in particular to a self-made household earthquake alarm device, belonging to the technical field of earthquake prediction. Background technique [0002] Earthquakes can be divided into longitudinal waves and transverse waves according to their propagation modes. Longitudinal waves are propulsion waves. The propagation speed in the crust is 5.5-7 km / s. It first reaches the epicenter. It causes the ground to vibrate up and down, which is less destructive; transverse waves are shear waves. The propagation speed of the wave in the crust is 3.4 km / s. The second one arrives at the epicenter. It makes the ground shake back and forth, left and right, which is more destructive, so it can be sensed when the longitudinal wave arrives, which is useful for reducing earthquake death. Rate helps a lot. [0003] my country is a country prone to earthquakes, and earthquakes will bring us huge casualties and material losses, especiall...
