Abstract
The invention discloses a household earthquake alarm. The household earthquake alarm comprises a machine shell, wherein a magnetic monitoring module, a P-wave monitoring module, a control circuit, an alarm body and a storage battery device are arranged in the machine shell. The magnetic monitoring module comprises a compass monitoring module and a magnetic-field-free monitoring module, wherein the compass monitoring module, a magnetic field monitoring module and the P-wave monitoring module respectively comprise a signal acquisition module, a signal amplification module and a signal transmission module. According to the technical scheme, the household earthquake alarm mainly uses the difference between the speed of an electromagnetic wave and the speed of an earthquake wave and the difference between the speed of a primary wave and the speed of a secondary wave to achieve timely early warning after an earthquake happens. The household earthquake alarm has the advantages that the household earthquake alarm is small, exquisite, convenient, and easy to carry and operate; due to the compass monitoring alarm, the magnetic-field-free monitoring alarm and the P-wave monitoring alarm, accuracy is high, and the precious escape time is provided for people.
Description
Technical field
The present invention relates to a kind of alarm, be specially a kind of earthquake siren for household, belong to earthquake pre-warning technical field.
Background technology
Earthquake, is the seismic wave that sharply breaks and produce that earth interior occurs, and causes within the specific limits the phenomenon of ground vibration.Earthquake (earthquake) is exactly epidermic fast vibration, is called again in ancient times earthquake.It is recurrent a kind of disaster on the earth just as tsunami, wind spout, freezing disaster.The earth vibration be earthquake the most intuitively, the most general performance.In seabed or the violent earthquake that occurs of coastal region, can cause huge wave, be called tsunami.Earthquake is extremely frequently, the whole world annual generation earthquake approximately 5,500,000 times.Global plate motion earthquake usually causes serious casualties, and fire hazard, floods, toxic gas leakage, bacterium and radiomaterial diffusion, also may cause the secondary disasters such as tsunami, landslide, avalanche, ground fissure.
In recent years, the frequent generation of various earthquake disasters, brings havoc not only to the mankind's living environment, and has seized the life of countless people's preciousnesses.Although current science and technology there is no the generation of method prediction earthquake, if can be before seismic event arriving time seconds or tens of seconds accurately earthquake is carried out to early warning, just can strive for valuable escape time for people.
Summary of the invention
The object of the invention is for a kind of earthquake siren for household is provided, to solve the problems referred to above of prior art.
The object of the invention is to be achieved through the following technical solutions:
, comprise casing, in casing, contain magnetic monitoring modular, P ripple monitoring modular, control circuit, alarm and accumulator plant; Described magnetic detection module is comprised of two parts: compass monitoring modular and without magnetic field monitoring modular; Described compass monitoring modular, magnetic field monitoring modular and P ripple detection module comprise signal acquisition module, signal amplification module and signal transmission module.
Described compass monitoring modular is comprised of a spherical compass and displacement transducer, displacement transducer is positioned at a side of spherical compass, detect in real time the change in location of pointer on spherical compass, when random rotary displacement transducer can occur spherical compass before earthquake, the signal collecting is sent in control circuit and is processed, control circuit is controlled alarm equipment alarm.
Described P ripple detection module is comprised of the horizontal P wave sensor of some groups of different directions, and P wave sensor is hollow columnar, and one end is mercury slug, and the other end is the positive and negative electrode being electrically connected to control circuit.When P wave sensor receives the pitching of P ripple of earthquake, mercury slug deforms or is mobile, thereby connects positive and negative electrode, and control circuit is controlled alarm equipment alarm.
Described is electrically connected to by magnetic switch and control circuit without magnetic field monitoring modular; In coming earthquake, as disorderly in there is magnetic field, can there is magnet demagnetization phenomenon in moment, magnetic switch is opened, and control circuit is controlled alarm equipment alarm.
Further, in order to prevent that the bad people of ear from can obtain early warning, is provided with alarm lamp on casing.
In order to prevent that child from closing alarm switch, alarm switch is arranged at bottom of shell; In order to prevent child's warner for moving, at bottom of shell, be provided with sticker.
To be horizontal in order installing, a level meter to be set on casing.
Further, in order to obtain reporting to the police comparatively accurately, prevent other vibrations wrong reports, comparison of wave shape module can be set in control circuit, by the comparison of wave shape of the shocking waveshape receiving and storage, and then determine whether seismic event.
The household alarm forming by technical solution of the present invention setting mainly utilize electromagnetic wave and seismic event, primary seismic wave and secondary wave velocity contrast realize timely early warning after the earthquake.The present invention has following beneficial effect: 1, compact volume and convenience, and portable; Simple to operate; 2, by compass monitoring, alarming, without magnetic field monitoring, alarming and the triple early warning of P ripple monitoring, alarming, accuracy is high, can strive for valuable escape time for people.
