Abstract
The utility model provides an earthquake detection sound alarm device, which mainly comprises an earthquake detection module, a master control module, a sound prompt module and the like. When an earthquake occurs, the obtained three-dimensional earthquake wave through the detection of the earthquake detection module is shaped, amplified and A / D-converted by the analog signal input circuit of the master control module, and is analyzed by a CPU circuit, and the corresponding earthquake magnitude is converted according to the Seeburg earthquake intensity scale, and is supplied to the sound prompt module by a sound output circuit to broadcast the current earthquake magnitude so as to prompt residents to quickly flee the danger zone. The earthquake detection sound alarm device is mainly installed on the surface of a building, and has the function of prompting the building position at which the earthquake occurs and the earthquake magnitude to the residents, so that the residents can timely flee from the danger zone.
Description
Affiliated technical field
The utility model relates to a kind of device of real-time detection earthquake magnitude, earthquake detection device that especially can the voice broadcast earthquake magnitude.
Background technology
At present, what known earthquake took place at first to arrive the face of land is compressional wave, and the velocity of propagation of compressional wave in the earth's crust is 5.5-7 thousand meter per seconds, and it makes the ground vertical tremor, destructive power a little less than.What arrive then is shear wave, and the velocity of propagation in the earth's crust is 3.2-4.0 thousand meter per seconds, and it makes ground that all around shake take place, and people can't stand and run, and destructive power is stronger.The several seconds that earthquake begins is before shear wave arrives, be the best opportunity of human escape, but because people seldom experience earthquake, brains is in space state when earthquake takes place, can't react is that earthquake has taken place, even if know earthquake has taken place, but do not know the size of earthquake magnitude, and be in nervous and panic state, can not the house that whether should leave the place be judged, wait to make a response, missed best escape opportunity, cause the mass casualties.If particularly earthquake occurs in night, people are waken up with a start from sleep soundly because of earthquake, but can't understand at once and what has taken place thereby when can not take effective actions, the consequence that is produced is just even more serious.And the seismic monitoring device that relevant department is provided with, though can make timely monitor and record to seismism, monitoring and record that relevant department just just makes according to the seismic monitoring device after earthquake are reported the earthquake that is taken place, and can not help the timely flee danger of people area.
Summary of the invention
The purpose of this utility model, be whether in order to overcome that people can not correctly make when earthquake takes place be the judgement of earthquake, and then the problem in flee danger area, provide a kind of and whether can detect earthquake, earthquake magnitude size and carry out voice prompt alarm and simple in structure, detect earthquake detection device with low cost.
The technical scheme that its technical matters that solves the utility model adopts is: this device comprises:
-earthquake detection module is made of acceleration transducer, is used to detect earthquake magnitude, i.e. the accekeration that earthquake was produced when taking place, and this accekeration is transformed into voltage signal;
-main control module, comprising:
-analog signal input circuit, its input end is connected with the output terminal of earthquake detection module, is used to receive the voltage signal of earthquake detection module output, and signal is carried out shaping, amplification and A/D conversion:
-central processing unit circuit adopts single-chip microcomputer, and its input end is connected with the output terminal of analog signal input circuit, is used for the signal of changing through A/D is analyzed, and converts according to western Burger scale of earthquake intensities, converses the sympathetic earthquakes grade;
-voice output circuit; Its input end is connected with the output terminal of central processing unit circuit, is used for giving voice cue module with the data transmission after the central processing unit processing of circuit;
-voice cue module, its input end is connected with the output terminal of voice output circuit, is used for reporting to the user grade of the earthquake of current generation, and the rapid flee danger of voice suggestion area.
The principle of this device is: when earthquake takes place, the seismic event that produces from focus is that outwards propagate at the center with the focus, the acceleration transducer that its acceleration is fixed on building surface receives with three dimensional form, and be transformed into voltage signal, this voltage signal carries out shaping through the analog signal input circuit of main control module, the A/D switched pins that sends central processing unit after the conditionings such as amplification again to is carried out the A/D conversion, the magnitude of voltage that obtains is an acceleration information, these data are converted according to western Burger scale of earthquake intensities in central processing unit, after conversing the sympathetic earthquakes grade, central processing unit is again by the voice output circuit, carry the earthquake magnitude voice signal to voice cue module, report earthquake magnitude by voice cue module then.
The beneficial effects of the utility model are: this device can carry out the voice broadcast earthquake magnitude and and guide the rapid flee danger of people area in the grade that detects occurent earthquake fast, has accelerated people's reaction velocity.In addition, simple in structure owing to this device only is made up of acceleration transducer and several module, detect with low cost.
