Description of drawings
Fig. 1 is the circuit diagram of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail:
With reference to Fig. 1, a kind of induction-type high-voltage safety alarm, it comprises induced electricity pole piece A, technotron VF, time-base integrated circuit IC1, speech IC IC2, audio-frequency amplifier tube V, loudspeaker BL, resistance R 1 and R2, potentiometer RP1 and RP2, capacitor C 1 and power supply GB, described resistance R 1, technotron VF and potentiometer RP1 form series circuit, induced electricity pole piece A is connected on the grid of technotron VF, the source electrode of technotron VF inserts 2 pin of time-base integrated circuit IC1,4 pin of time-base integrated circuit IC1 and 8 pin connect power supply GB positive pole, 1 pin connects power supply GB negative pole, 5 pin insert power supply GB negative pole by capacitor C 1,3 pin connect 2 pin of speech IC IC2 by potentiometer RP2, insert resistance R 2 between 3 pin of speech IC IC2 and the power supply GB positive pole, 1 pin is directly received power supply GB negative pole, the base stage of audio-frequency amplifier tube V connects output terminal 4 pin of speech IC IC2, is connected to loudspeaker BL between the positive pole of the collector of audio-frequency amplifier tube V and power supply GB.
Described induced electricity pole piece A adopts scale copper to make, resistance R 1 and R2 all adopt the 1/4W carbon film resistor, capacitor C 1 is selected dacron terylene condenser for use, technotron VF selects the 3DJ6 field effect transistor for use, audio-frequency amplifier tube V selects S9013 silicon NPN transistor for use, time-base integrated circuit IC1 selects the NE555 time-base integrated circuit for use, and speech IC IC2 selects the NFC5212 speech IC for use, and loudspeaker BL selects 0.5W, 8 Ω D.sp.s for use.
The course of work of the present utility model: at nobody during near induced electricity pole piece A, resistance value is less between the leakage of technotron VF, the source electrode, electric current is bigger, the 2 pin current potentials of time-base integrated circuit IC1 are higher than 1/3 of power supply GB total voltage, and time-base integrated circuit IC1 is failure to actuate.As the people during near induced electricity pole piece A, the induced signal of human body can make the leakage of technotron VF, the resistance value between the source electrode increase, the 2 pin current potentials of time-base integrated circuit IC1 are lower than 1/3 of power supply GB total voltage, 3 pin of time-base integrated circuit IC1 become high level by low level, speech IC IC2 is triggered and work, the voice signal of the 4 pin output of speech IC IC2 sends phonetic warning sound by loudspeaker BL after audio-frequency amplifier tube V amplifies.
At last, it is also to be noted that what more than enumerate only is specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
