Working principle:
1. under normal circumstances, the infrared ray that infrared transmitting tube D1 is issued, is received, infrared receiver by infrared receiver tube D2
Pipe D2 resistance becomes smaller, and a point (other end of resistance R2) voltage reduces, and field-effect tube Q1 is not turned on, and the grid of field-effect tube Q2 obtains
Less than voltage, it is not turned on.Buzzer HA does not alarm, and light emitting diode D4 is not glittering.
2. when an earthquake occurs, the plastic light guide among infrared transmitting tube D1 and infrared receiver tube D2 is because of vibration generation
Displacement, the infrared ray of sending are blocked, and infrared receiver tube D2 can not receive infrared ray, and infrared receiver tube D2 resistance becomes larger, a point
Voltage rises, and field-effect tube Q1 conducting, voltage diode is transmitted to capacitor C1 through D3 and charges.Switching circuit triggering (is opened when being when being
Powered-down routing diode D3, capacitor C1, triode Q2 composition), buzzer HA alarm, while light emitting diode D4 is glittering.
Voltage detecting: the voltage detecting circuit being made of operational amplifier LM358 U1, triode Q3, voltage-stabiliser tube D6 etc.,
When battery expires electricity 3.7V, the 3 foot voltages of operational amplifier U1 are higher than the 2 foot voltages of operational amplifier U1, operational amplifier U1
1 foot export high potential, Q3 conducting, light emitting diode D5 is bright.When cell voltage is lower than 2.8V, 3 feet of operational amplifier U1
Voltage is lower than the 2 foot voltages of operational amplifier U1, and operational amplifier exports low potential, and triode Q3 is not turned on, light emitting diode
D5 does not work, it was demonstrated that undertension reminds charging in time.
Application method:
1. the present apparatus is placed on smooth desktop, it is first turned on power switch.
2. adjusting four balance screws, the light for issuing infrared transmitting tube D1 is radiated at by the intermediate void of plastic tube
Infrared receiver tube D2.At this moment it because infrared receiver tube D2 resistance becomes smaller, does not alarm.
3. using cloche, probe is covered, can be kept out the wind, prevents to report by mistake.
4. when an earthquake occurs, whether shear wave or longitudinal wave, plastic tube can all vibrate deviation original position.Infrared ray is obstructed
And it alarms.
5. can all be moved so having and slightly vibrating, because plastic tube is sling with soft cotton thread so having very high
Sensitivity.
6. device uses electronic circuit, there is timing circuit, and have voltage detecting circuit, there is very high reliability.
