Description
Technical field
This utility model relates to gate inhibition's technical field of burglary prevention, particularly a kind of antitheft gate inhibition for market, the non-stealer of the noiseless prompting of library。
Background technology
In order to prevent stolen articles, in market, the exit of library be generally fitted with antitheft gate inhibition。The circuit part major part of existing antitheft gate inhibition is all that magnetic conduction circuitry directly connects buzzer and constitutes, if such antitheft gate inhibition have the special article of non-demagnetization near time will report to the police。But in most cases, the carrier of non-demagnetization article is not intended that pilferage article, and it is unsuccessful or misplaced by article in oneself bag to be because mechanical disorder demagnetization。Such false alarm can be greatly increased the working strength of guard, even the fame of carrier by mistake can be caused damage, and ear-piercing chimes of doom also can bother other people of study or work。
Summary of the invention
The purpose of this utility model is to provide a kind of antitheft gate inhibition with prompting function。
Problem to be solved in the utility model is the defect that existing antitheft gate inhibition's false alarm rate is high。
For realizing the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of antitheft gate inhibition with prompting function of this utility model, including doorframe, buzzer, LED notice board, Infrared laser emission device, power supply, photoconductive resistance, magnetic induction switch a, magnetic induction switch b, resistance a, resistance b and audion, described buzzer is arranged on doorframe top, LED notice board has two pieces, above LED notice board is embedded in doorframe side, left and right；Infrared laser emission device is arranged on the doorframe of left side, and photoconductive resistance is arranged on the doorframe of right side, and position is just installed by Infrared laser emission device and photoconductive resistance；Power supply accesses on the left of doorframe, and door money is internally installed magnetic induction switch a, magnetic induction switch b, resistance a, resistance b and audion；Infrared laser emission device is series on magnetic induction switch a and power supply, and magnetic induction switch b mono-end is connected to magnetic induction switch a, and the other end is connected to resistance a, resistance a and photoconductive resistance series connection is followed by power cathode；Resistance b mono-end is connected to magnetic induction switch b and resistance a joint, and the other end is connected to the C level of audion, and the B level of audion is connected to photoconductive resistance and resistance a junction, and audion E level connects one end of buzzer, and the buzzer other end is connected to power cathode；LED notice board is in parallel with Infrared laser emission device；Magnetic induction switch a distance of reaction is 3 meters, and magnetic induction switch b distance of reaction is 0.5 meter, and audion is NPN type。
The utility model has the advantages that: when there being people to carry unintentionally the article of non-demagnetization near outlet 3 meters of scopes of gate inhibition, magnetic induction switch a can connect LED notice board and people is pointed out, Infrared laser emission device is in an ON state simultaneously, if people receives prompting and is given back by the article of non-demagnetization or carry out degaussing operation, magnetic induction switch a can disconnect, and whole circuit is in off state；If people insists on taking article out of, when 0.5 meter of scope of gate inhibition, connecting magnetic induction switch b, when people is by gate inhibition, red laser is occluded, and now buzzer will produce alarm；This utility model can reduce false alarm rate to the full extent, to staff and other people bring great convenience, suitable for large-scale promotion。

Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further described。
As shown in the figure, a kind of antitheft gate inhibition with prompting function of this utility model, including doorframe 1, buzzer 2, LED notice board 3, Infrared laser emission device 4, power supply 5, photoconductive resistance 6, magnetic induction switch a7, magnetic induction switch b8, resistance a9, resistance b10 and audion 11, described buzzer 2 is arranged on doorframe 1 top, LED notice board 3 has two pieces, above LED notice board 3 is embedded in left and right doorframe 1 side, buzzer 2 and LED notice board 3 play the effect of sound and light alarm；Infrared laser emission device 4 is arranged on the doorframe 1 of left side, and photoconductive resistance 6 is arranged on the doorframe 1 of right side, and position is just installed by Infrared laser emission device 4 and photoconductive resistance 6；Power supply 5 accesses on the left of doorframe 1, and door money is internally installed magnetic induction switch a7, magnetic induction switch b8, resistance a9, resistance b10 and audion 11；Infrared laser emission device 4 is series on magnetic induction switch a7 and power supply 5, and magnetic induction switch b8 mono-end is connected to magnetic induction switch a7, and the other end is connected to resistance a9, resistance a9 and photoconductive resistance 6 series connection is followed by power supply 5 negative pole；Resistance b10 mono-end is connected to magnetic induction switch b8 and resistance a9 joint, the other end is connected to the C level of audion 11, the B level of audion 11 is connected to photoconductive resistance 6 and resistance a9 junction, and audion 11E level connects one end of buzzer 2, and buzzer 2 other end is connected to power supply 5 negative pole；LED notice board 3 is in parallel with Infrared laser emission device 4；Magnetic induction switch a7 distance of reaction is 3 meters, and magnetic induction switch b8 distance of reaction is 0.5 meter, and audion 11 is NPN type。
This utility model using method: when there being people to carry unintentionally the article of non-demagnetization near 3 meters of scopes of gate inhibition, magnetic induction switch a7 closes, people is pointed out by circuit ON LED notice board 3, is also turned on Infrared laser emission device 4, and the light direct beam that Infrared laser emission device 4 sends is to photoconductive resistance 6；If people sees prompting and the article of non-demagnetization given back or carried out degaussing operation, magnetic induction switch a7 will not receive magnetic signal, and switch can disconnect, and whole circuit is in off state；If people insists on taking article out of, when 0.5 meter of scope of gate inhibition, magnetic induction switch S2 closes, photosensitive circuit and buzzer 2 circuit can be connected, now owing to the direct projection of Infrared laser emission device 4 makes photoconductive resistance 6 resistance only small, electric current does not flow through buzzer 2 circuit, alarm will not be produced, when light is covered by the people of gate inhibition, photoconductive resistance 6 resistance becomes very large, weak current is made to flow into the B level of audion 11, a big electric current has been made to flow through C level and E level, audion 11 is turned on, now, buzzer 2 circuit ON, buzzer 2 will produce alarm, then processed by Security Personnel；The people by mistake carrying non-demagnetization article can be reminded by this utility model, also can stealing be reported to the police, it is possible to reduce false alarm rate to the full extent simultaneously, to staff and other people bring great convenience, suitable for large-scale promotion。
