Civil earthquake detecting and voice warning device

Abstract

The invention provides an earthquake detecting and voice warning device which mainly comprises an earthquake detecting module, a main control module, a voice prompting module and the like. When an earthquake occurs, the device can be used according to the following steps: using the earthquake detecting module to detect earthquake and obtain three-dimensional earthquake waves, using an analog signal input circuit of the main control module to process the three-dimensional earthquake waves in manner of shaping, magnification and A / D conversion, and analyzing the three-dimensional earthquake waves by a central processing unit (CPU) circuit; calculating the corresponding earthquake magnitude according to a Seaborg earthquake intensity scale, and then, supplying the corresponding earthquake magnitude to the voice prompting module through a voice output circuit; and broadcasting the current earthquake magnitude to prompt residents to quickly escape from danger areas. The earthquake detecting and voice warning device is mainly installed on the surface of a building to prompt the earthquake occurrence and the earthquake magnitude in the position of the building for residents, thereby achieving the purpose of enabling the residents to escape from the danger areas in time.

Description

Technical field [0001] The invention relates to a device for real-time detection of earthquake grades, in particular to an earthquake detection device capable of voice broadcasting of earthquake grades. Background technique [0002] At present, it is known that the first earthquake to reach the surface is the longitudinal wave, and the propagation speed of the longitudinal wave in the earth's crust is 5.5-7 km / s, which makes the ground vibrate up and down and has weak destructive power. Then it arrives at the shear wave, whose propagation speed in the earth's crust is 3.2-4.0 km / s, which makes the ground shake back and forth, left and right, people cannot stand and run, and have strong destructive power. The first few seconds of an earthquake is the best time for humans to escape before the shear wave arrives. However, because people seldom experience earthquakes, their minds are in a blank state when an earthquake occurs, and they cannot respond that an earthquake has occur...
