Description
Technical field
The present invention relates to the technical field of earthquake alarm, more particularly to a kind of buried LASER Light Source earthquake alarm dress of optical fiber
Put.
Background technology
Earthquake is the destructive natural calamity that a kind of impersonal force can be resisted, and earthquake can cause huge in moment
Destructive power, earthquake happen occasionally from ancient times, and because manpower can not resist, what can be done is exactly to find in advance, gives warning in advance, removes in time
From, so earthquake prewarning device causes the great attention of the mankind, there are the generation that seismograph can predict earthquake in ancient times, earthquake it
It is preceding also have many peculiar geographical phenomenons can effective foreseeing earthquake, such as the exception table of the Novel presentation of animal and weather
It is existing, but because the development of industrialization and urbanization, this natural prediction method have not applied to, nowadays all set in many places
Earthquake prewarning device is equipped with, is the crystallization of modern science and technology, but effect is not fine, has not been well positioned to meet people's
Demand.In China, natural calamity is caused in personnel death's ratio, and earthquake disaster proportion is up to 54%, is that China causes personnel
Dead most natural calamity.Earthquake disaster not only damages national economy, and directly contributes people's life, the huge damage of property
Lose, before devastatingly seismic wave not yet reaches in several seconds or tens of seconds, earthquake information is announced extraneous, personnel can be substantially reduced
Injures and deaths.Theoretical research shows, if pre-warning time is 3 seconds, can make casualties than reducing 14%；If 10 seconds, people
Member's injures and deaths are than reducing 39%.Therefore, it is always the side that people work hard to establish timely, accurate and effective earthquake warning system
To.
At present, seismic survey and the more seismic survey centers professional in country of warning device or scientific research institution use, due to
These machines are accurate, huge, expensive, and the sensor of these seismic survey devices will be placed into specific region and specific
Depth, use can not be popularized in resident's daily life, when earthquake disaster occurs, resident can not receive alarm the very first time and carry
Show, and keep away calamity in time, people are often caught unprepared, it is difficult to casualties and property loss are reduced to minimum level, it is existing
Earthquake alarm system is big there is also floor space, and the forecast is inaccurate really, and cost is high, the shortcomings that being unfavorable for promoting the use of.
Earthquake intensity is divided into 12 degree by China, and the earthquake of different earthquake intensitys, it influences and destroyed substantially as follows：It is less than
Three degree of people's insentiences, only instrument can just recorded；Three degree are felt in the dead of night people；People's meeting of four~five degree of sleeps
Wake up with a start, pendent lamp rocks；Six degree of vessel are toppled over, house slight damage；Seven~octave house is destroyed, and crack occurs in ground；
Nine~ten degree of house collapses, ground failure are serious；11~12 degree of destructive destructions.
