Background technology
When in a single day earthquake occurred in the late into the night, people slept soundly in the room, made people hard to guard against, and this is to people's life extent of injury maximum.When 20 days 8 April in 2013: 02(weekend) 7.0 grades of earthquakes take place Yaan, China Sichuan, there are a lot of people also sleeping soundly.If can be in the moment of earthquake early period of origination, if can win tens second time, a lot of people just might brush past with permanent disability or Death.Earthquake be damage envelope wide, cause life with property is very harmful and be a kind of irresistible disaster, science cognition so far fails effectively to grasp the pests occurrence rule of earthquake, does not also reach far away to resemble the level of forecasting the weather.
Earthquake can be when taking place more than 4 grades in earthquake generation electronic early warning device of the present invention, this prior-warning device can be at extremely short time supervision to first seismic event, earthquake generation electronic early warning device can start audible alarm in moment, wakes in sleeping soundly you immediately.Before violent earthquake takes place, can be you and win tens second extremely valuable departure time, help you and household to evacuate to the safety area rapidly, even can only win several seconds escape time, also can reduce earthquake significantly to the harm of people's life.Earthquake generation electronic early warning device of the present invention is particularly suitable for using in the take place frequently places such as resident family, school, hospital in area of earthquake.
Earthquake generation electronic early warning device is formed the bridge balance circuit with two NPN transistor, this technical scheme has been simplified circuit structure, has reduced manufacture difficulty and the cost of prior-warning device, has realized the requirement of monitoring sensitivity height, reliable working performance.
In case when running into certain road monitoring probe and being touched, with high loudness hummer alarm, the alarm signal is once sounding immediately for this device, the bridge balance circuit will be kept locking automatically, can stop the phenomenon generation of reporting by mistake or failing to report fully.
Below describe earthquake generation electronic early warning device of the present invention related relevant technologies content in implementation process in detail.
Summary of the invention
Goal of the invention and beneficial effect: earthquake generation electronic early warning device of the present invention can monitor first seismic event rapidly when earthquake takes place more than 4 grades, it can start audible alarm in moment, wakes in sleeping soundly you immediately.Before violent earthquake takes place, can be you and win tens second extremely valuable departure time, help you and household to evacuate to the safety area rapidly, even can only win several seconds escape time, also can reduce earthquake significantly to the harm of people's life.Earthquake generation electronic early warning device of the present invention is particularly suitable for using in the take place frequently places such as resident family, school, hospital in area of earthquake.
Earthquake generation electronic early warning device is formed the bridge balance circuit with two NPN transistor, this technical scheme has been simplified circuit structure, has reduced manufacture difficulty and the cost of prior-warning device, has realized the requirement of monitoring sensitivity height, reliable working performance.In case when running into certain road monitoring probe and being touched, with high loudness hummer alarm, the alarm signal is once sounding immediately for this device, the bridge balance circuit will be kept locking automatically, can stop the phenomenon generation of reporting by mistake and failing to report fully.

Be example with the 2 road monitoring channel: when the moment that earthquake more than 4 grades takes place, monitoring probe SK2 will rock suddenly and is switched on that (actual monitoring probe SK2 does not need dead short along with the earth, as long as can have influence on the resistance of resistance R 6), the equilibrium state of bridge balance circuit will be broken, a in circuit point current potential is higher than b point current potential so, NPN transistor BG2 obtains normal bias voltage and conducting, PNP transistor BG3 passes through because electric current is arranged, then PNP transistor BG3 will become conducting by ending, germanium diode D1 makes the base stage of NPN transistor BG2 remain noble potential by by becoming conducting.At this moment, even if monitoring probe SK2 disconnects or conducting more again because of latter earthquake in the 2 road monitoring channel, PNP transistor BG3 also will continue to keep conducting state (keeping memory), hummer HA remained pipe.
In like manner, principle of work and the course of work of the monitoring probe SK1 in the 1st monitoring channel are the same.
The alarm signal is once sounding, and lock-in circuit will keep automatically, and alert news is removed must be by household's shearing device direct supply, the direct supply of engaging means again, and circuit just can return to initial equilibrium conditions (the circuit balancing state resets).
