Patent ZL00247793.9 discloses a kind of laser burglar alarm, this device utilizes laser generator to make laser beam irradiation to the photodiode D1 of optical signal receiver as shown in Figure 1, and this moment, D1 was low-resistance, the BG1 base stage is in electronegative potential, and all devices are on the alert.Get over when setting up defences the zone as the people, because of lasing light emitter is blocked by human body, D1 loss of gloss and be high resistant, make the BG1 base stage be noble potential and conducting, BG2 and J1 also must conduct simultaneously, at this moment the normally opened contact adhesive of J1, make the energising of 555 o'clock base integrated package the 2nd pin and trigger, enter timed sequence, simultaneously J2 gets electric adhesive and connects warning lamp 1 and alarm bell 2, and makes the adhesive of J3 normally opened contact and connect phone 3 and report to the police.It is simple that this device is used for antitheft monitoring of structures, but can not be used for the identification and the warning of electric power safety monitoring.
Summary of the invention
The purpose of this utility model provides a kind of staff when crossing over fence and entering charged position, and can effectively discern and can accurately survey, and the low electronic laser safe fence alarm device of rate of false alarm.
Electronic laser safe fence alarm device of the present utility model includes laser generator and light signal receiving alarm device, light signal receiving alarm device receives the laser that is sent by laser generator, electronic laser safe fence alarm device of the present utility model also includes at least 1 laser reflective mirror, the laser refraction that is used for laser generator is sent becomes a safe fence to light signal receiving alarm device by laser generator, laser reflective mirror and light signal receiving alarm device common coil.
Usually, described electronic laser safe fence alarm device is the safe fence that is become a rectangle by 1 laser generator, 3 laser reflective mirrors with 1 light signal receiving alarm device common coil, laser generator and light signal receiving alarm device are in the place, a summit of a rectangle together, and 3 laser reflective mirrors lay respectively at the place, 3 summits in addition of rectangle.
Described laser generator is made of laser diode and dry cell.
Described light signal receiving alarm device is connected in series successively by light signal reception passivation time delay unit, signal amplification unit, self-locking timing unit and execution alarm unit and constitutes.
Described light signal receives passivation time delay unit and is made of capacitor C 1, the adjustable resistance R5 of series connection and the photodiode D1～D48 parallel connection of connecting, and is parallel with K switch 1～K48 respectively on described photodiode D1～D48.
Described execution alarm unit is made up of MP3m2 and loudspeaker m3 series connection back warning light m1 in parallel.
The principle that the utility model can not suddenly change according to capacitor voltage at both ends, the two ends of photodiode D1～D48 and connect capacitor C 1 in light signal receive time delay element circuit, to not bringing the disturbing factors such as object of harm can not produce the mistake alarm, improved the accuracy of this device greatly to safety.Simultaneously, adopt laser, make this device have the distance of setting up defences, advantage that scope is big as optical signal source.

Embodiment
Electronic laser safe fence alarm device of the present utility model is made up of laser generator 1, laser reflective mirror 2 and light signal receiving alarm device 3 three parts.Wherein, laser generator 1 is made of laser diode and dry cell.The laser that laser generator 1 sends is received by light signal receiving alarm device 3 after 2 reflections of laser reflective mirror.
As shown in Figure 2,1 laser generator 1 and 1 light signal receiving alarm device 3 are in together a bit, 3 laser reflective mirrors 2 lay respectively at other 3 points, common coil becomes the virtual secure fence of a rectangle, the laser that laser generator 1 sends is received by light signal receiving alarm device 3 after 3 laser reflective mirror 2 right angles reflections.
Light signal receiving alarm device 3 is connected in series successively and is constituted by light signal reception passivation time delay unit, signal amplification unit, self-locking timing unit, execution alarm unit.Its circuit as shown in Figure 3, capacitor C1 is with after adjustable resistance R5 connects, be attempted by the two ends of photodiode D1～D48, constitute light signal and receive passivation time delay unit, its passivation time delay is regulated by adjustable resistance R5, can not give the alarm to not bringing the object of harm such as flying bird to pass through to wait disturbing factor to influence to safety.Photodiode D1～D48 respectively and meet normal open switch K1～K48, for obsolete photodiode, the switch of can closed pair answering is to excise from circuit.Signal amplification unit comprises triode BG1, BG2 and relay J 1, be serially connected with resistance R 3 and adjustable resistance R1 between the base stage of triode BG1 and the positive supply successively, be serially connected with resistance R 4 and adjustable resistance R2 between its collector and the positive supply successively, its emitter connects the base stage of triode BG2, the grounded emitter of triode BG2, collector is connected with the coil of relay J 1.The normally opened contact of relay J 1 inserts 2 pin of 555 o'clock base integrated package IC1 in the self-locking timing unit, connect successively with adjustable resistance R8, resistance R 7 behind 6, the 7 pin short circuits of ic chip 1, insert 4,8 pin of integrated package IC1, by regulating the timing that adjustable resistance R8 regulates ic chip 1.3 pin of ic chip 1 are connected with the coil of relay J 2 by diode D3, and the normally opened contact of relay J 2 is connected and carried out alarm unit.Carry out alarm unit and be made up of MP3m2 and loudspeaker m3 series connection back warning light m1 in parallel, its voice warning is connected by the normally opened contact of relay J 2 and is realized.
