Brief description of the drawings

Fig. 1 is the structural representation of multi-functional rescue beacon.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model example is carried out clear Chu, it is fully described by.

Referring to Fig. 1, a kind of multi-functional rescue beacon, including switch S1, power supply DC, lamp H1, earphone XJ, loudspeaker BL, core Piece IC2, transformer T, controllable silicon VS, microphone BP, chip IC 1, resistance R1 and triode VT；The switch S1 connection power supplys DC, other end connecting valve S2, switch S2 connections lamp H1, lamp H1 connection earphone XJ；The earphone XJ connections loudspeaker BL, raises one's voice Device BL connection electric capacity C5, electric capacity C5 connecting valve S3-2, switch S3-2 connections chip IC 2 and electric capacity C6, electric capacity C6 connection transformation Device T；The transformer T is sequentially connected controllable silicon VS, lamp H2 and voltage input end；The connection electric capacity C2 of chip IC 2 and electric capacity C1, electric capacity C1 connection microphone BP and switch S3-1, switch S3-1 connection resistance R2 and triode VT；The triode VT connections 4th pin of chip IC 1, the 2nd pin connection resistance R1 of chip IC 1, the 3rd pin of resistance R1 connections chip IC 1；Chip IC1 model KD9561, the model LM386 of chip IC 2.

Operation principle of the present utility model is：Referring to Fig. 1, the multi-functional rescue beacon of the utility model, complete machine is reported by calling for help Alert signal generating circuit, audio power amplifier circuit, acoustic control color lamp metronome and several parts of change-over switch are constituted；When power turn-on switch S1, change-over switch S2 put 2, when S3 puts 1, and the machine, which is in, calls for help alarm condition, the calling for help being made up of IC1 music integrated circuits Alarm signal generator is triggered conducting, and the alarm signal of generation is through the preposition amplifications of triode VT, then through audio power amplifier circuit IC2 Amplification, rear class C5 promotes loudspeaker BL to send calling for help alarm signal；When S2 puts 3, small bulb H1 electrified light emittings are now illumination State, when S2 puts 2, and S3 puts 2, microphone BP amplifies microphony signal through electric capacity C1 coupled to IC, and is sent out by earphone Sound, plays hearing aid effect, when the sound is released by loudspeaker, so that it may play the effect of amplifying；When S2 put 2, S3 put 3 when, After voice signal exports microphony signal, amplified again through IC2 through microphone BP, by transformer T coupled to one-way SCR VS's Control pole G, VS is with the size of voice signal for triggering, when and turn on, when and end, color lamp H2 is glistened；When S2 puts 2, S1 Two ends simultaneously connect bell button line, and the machine can be used as doorbell；In circuit, R1 is that tone adjusts resistance, and C1, C5 are coupled capacitor Device, C2 is IC2 Gain tuning electric capacity.
