Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is wiring diagrams of control circuit of the present utility model;
Among the last figure: contact A, casing 1, plug 2, switch 3, LED, loudspeaker SP, fuse RD, alarm lamp L; Time base circuit NE555, relay K M, regulator block 7812, speech chip IC2, power amplifier IC3, transformer T, bridge heap QL, loudspeaker SP; Resistance R 1-R6, capacitor C 1-C9, diode V1.
Embodiment
1-2 in conjunction with the accompanying drawings, the utility model will be further described:
The utility model comprises contact A, casing 1, plug 2, switch 3, LED, loudspeaker SP, alarm lamp L and control circuit, be provided with control circuit in casing 1 inside, the front end of casing 1 is provided with contact A, one side is provided with the plug 2 of energized, the top is provided with switch 3, LED, alarm lamp L and loudspeaker SP, and described contact A is installed on door handle or the window.
Wherein, control circuit comprises time base circuit NE555, relay K M, regulator block 7812, speech chip IC2, power amplifier IC3, transformer T, bridge heap QL, loudspeaker SP, resistance R 1-R6, capacitor C 1-C9, diode V1, power supply is through bridge heap QL rectification, capacitor C 9 filtering by transformer T, after passing through regulator block 7812 voltage stabilizings again, provide 12 volts of stable DC voltage, supply with late-class circuit and use; Time base circuit NE555 is connected into monostable circuit, and output terminal connects LED and speech chip IC2 and alarm lamp L by relay K M, and the output terminal of speech chip IC2 connects loudspeaker SP by power amplifier IC3; The input end connecting terminal A of time base circuit NE555.Above-mentioned speech chip IC2 adopts 9561 serial speech chips; Above-mentioned power amplifier IC3 adopts the TDA2008 power amplifier.
Its principle of work is: time base circuit NE555 is connected into monostable circuit, and 2 pin are trigger end; After the energized, time base circuit NE555 is in reset mode, 3 pin output low levels, and 12 volts of relay K M that 3 pin connect do not have electricity and are failure to actuate, and the indication LED of reporting to the police does not work.When the burglar forces open the door, touch sense contact A, the noise signal of human body sensing pulls down to earth potential to 2 pin level, the monostable circuit upset, 3 pin output high level, the indication LED of reporting to the police is bright, and relay K M gets the electronic adhesive of doing, its normal opened contact KM1 closure, connect the IC2 voice sheet circuit that " catches a thief ", voice signal is added to 1 pin of power amplification circuit IC3 TDA2008 through capacitor C 5, through power amplification, loudspeaker just produces the chimes of doom of loud " catching a thief ", this sound can be to frighten the robber away, and the people around also giving simultaneously reminds this Lou Zhongyou robber, play the caution preventive effect, resident or operator on duty can take the precautionary measures.Another connects lighting scene to normal opened contact KM2 closure when audible alarm is arranged, realizes sound and light alarm, particularly can give the more intense deterrent force of robber at night.
