When the earthquake that takes place more than 4 grades, search switch SQ will be switched on along with rocking of the earth, and this moment, direct supply DC triggered unidirectional thyristor VS conducting through resistance R 1 and search switch SQ.The unidirectional thyristor VS conducting that in a single day is triggered, just can keep conducting state always, make bulb HL get electroluminescence, simultaneously integrated circuit (IC) 1 also electric work, the output terminal output internal memory analog alarm signal of integrated circuit (IC) 1, alarm signal promotes loudspeaker BL and sends loud alarm song after the direct couoling power amplifying circuit that NPN triode VT1, PNP triode VT2 constitute amplifies.

In the circuit of alarm set, resistance R 2 is external oscillation resistances of integrated circuit (IC) 1, changes the tone that its resistance can be regulated alarm song, and pushbutton switch SW is the cancel switch of alarm signal.

Description of drawings

Accompanying drawing is the embodiment circuit working schematic diagram that the invention provides an earthquake arriving acousto-optic alarm set.

Embodiment

Implement according to the circuit working schematic diagram of the arriving of earthquake shown in accompanying drawing acousto-optic alarm set and the components and parts technical requirement of description of drawings and the following stated, can realize the present invention.

The selection of components and parts and technical parameter thereof

VS selects common MCR100-6 or small-sized plastic packaging unidirectional thyristor such as BT169,2N6565 for use.

IC1 selects KD-9561 type four tones of standard Chinese pronunciation simulated sound integrated circuit for use.This integrated circuit adopts Soft Roll envelope form, and chip size is 32.5mm * 10mm.SE1 in the four tones of standard Chinese pronunciation simulated sound integrated circuit (IC) 1 end and SE2 end are two selected songs ends, and when the positive pole of the SE1 connection circuit among the IC1 VCC, SE2 hold when unsettled, IC1 exports police whistle sound; When the end of the SE1 among the IC1, when the SE2 end all meets VSS, be alarm song; SE1 end in IC1 is unsettled, and the SE2 among the IC1 holds when meeting VCC or VSS respectively, will send machine gun sound or fire engine sound.In the circuit of embodiment, what select for use is alarm song.Also can select any head in all the other 3 first songs, the connection that SE1 holds and SE2 holds that only needs to change among the IC1 gets final product.

Triode VT1 selects the NPN low-power transistor of 2SC9014 or 3DG6 class for use, requires magnificationfactor＞50; Triode VT2 selects pliotron among the C8550 type PNP, magnificationfactor＞80 for use.

Resistance R 1, R2 all use the small-sized carbon resister of RTX-1/8W type, the resistance 1.2K Ω of resistance R 1, the resistance 240K Ω of resistance R 1.

HL selects 3.8V, the 0.3A bulb of electric torch special use for use for the illumination bulb.

BL is a loudspeaker, selects the small-bore coil-moving speaker of impedance 8 Ω, 0.25W for use.

From resetting the normally closed type pushbutton switch, also available general single-pole single-throw switch (SPST) replaces SW with small-sized.

DC is a direct supply, and voltage is 4.5V, and No. 5 alkaline battery tandem compounds of available 3 joints become.

Circuit production and debugging

The time should be specifically noted that in welding: the shell of electric soldering iron is must ground connection good, punctures the cmos circuit of integrated circuit (IC) 1 inside to avoid ac induction voltage! 6 pads on the integrated circuit (IC) 1 can weld by lead and printed circuit board.

The sash weight that the optional building of tup among search switch SQ craftsman uses, plumb line is used the multiply metal wire instead and is come ceiling hammer, and metal ring selects for use the copper wire of ￠ 2mm to be bent into.

Gap between tup and the metal ring can be regulated by the method for lifting tup, and general gap is adjusted at 1.5～2.5mm and is advisable.Gap between tup and the metal ring is more little, and the sensitivity of warning is high more.In order to guarantee that alarm set has enough warning sensitivities, the support height that is used for fixing the hanging tup should be greater than 1.6m.

During use, this alarm set is placed in is not subject to extraneous vibration in the bedroom or blows wait the corner of disturbing, connect that the circuit of alarm set promptly enters the earthquake state that monitors behind the power supply, circuit consumes electric power hardly at this moment.Just in case run into the people for causing the alarm set false triggering, as long as press pushbutton switch SW, can releasing sound, light reports to the police.In addition, pay special attention to make regular check on the electric weight of alarm set battery and the validity of alarm set work.
