Abstract
The invention discloses a high-accuracy infrared anti-theft warning system which comprises an infrared detector, a signal amplification circuit, a comparison circuit, a delay circuit and a warning circuit. The signal amplification circuit, the comparison circuit, the delay circuit and the warning circuit are sequentially connected to form a circular loop. The infrared detector is connected with a display circuit. The infrared detector, the signal amplification circuit, the comparison circuit, the delay circuit, the warning circuit and the display circuit are respectively connected with a voltage-stabilized power supply. The high-accuracy infrared anti-theft warning system can be arranged in a warehouse in effectively concealed mode by aid of invisibility of infrared light, is prevented from being damaged by lawbreakers, and is improved in safety. Simultaneously, due to the comparison circuit and the delay circuit which are additionally arranged, the high-accuracy infrared anti-theft warning system can effectively improve warning accuracy and avoids unnecessary loss caused by alarm false alarming.
Description
Technical field
The present invention relates to a kind of alarm device, the warning system of especially a kind of high precision infrared theftproof.
Background technology
Along with the development of society and improving constantly of living standards of the people, safety becomes the problem of a care in people's life just gradually, and in order to improve inhabitation, storage environment, burglar alarm is installed becomes a good selection.What present use was more is to utilize magnetic switch control junction closure, realizes the alarm of alarm function, and this alarm arrangement is simple, and the alarm precision is relatively high, but owing to himself characteristic, the installation site is easy to be found, and disguise is relatively poor.
Summary of the invention
Goal of the invention: the objective of the invention is in order to overcome the deficiencies in the prior art, provide good concealment and alarm precision high infrared theftproof warning system.
Technical scheme: in order to solve the problems of the technologies described above, a kind of high precision infrared theftproof of the present invention warning system, comprise infrared eye, signal amplification circuit, comparator circuit, delay circuit, circuit for alarming, foregoing circuit is in turn connected to form loop checking installation, described infrared eye is connected with display circuit, and described infrared eye, signal amplification circuit, comparator circuit, delay circuit, circuit for alarming, circuit are connected respectively at stabilized voltage supply.
Described infrared eye is pyroelectric infrared sensor.
Beneficial effect: compared with prior art, advantage of the present invention is: the present invention is by utilizing the invisibility of infrared light, effectively in hidden installation and the warehouse, avoid being destroyed by the lawless person, improve security, simultaneously the present invention is by increasing comparator circuit, delay circuit, and the accuracy of can Effective Raise reporting to the police is avoided causing unnecessary loss because of the warning horn wrong report.
Description of drawings
Fig. 1 is the schematic diagram of high precision infrared theftproof warning system.
Embodiment
The present invention is described in further detail below in conjunction with embodiment, should understand these embodiment and only be used for explanation the present invention and be not used in and limit the scope of the invention.
The warning system of a kind of high precision infrared theftproof, comprise infrared eye, signal amplification circuit, comparator circuit, delay circuit, circuit for alarming, foregoing circuit is in turn connected to form loop checking installation, described infrared eye is connected with display circuit, and described infrared eye, signal amplification circuit, comparator circuit, delay circuit, circuit for alarming, circuit are connected respectively at stabilized voltage supply.
Pyroelectric infrared sensor detects the variation of human body temperature in the time of in human body enters the security area, cause the variation of receiving trap output signal, relatively produce by analysis alarm signal, described amplifying circuit amplifies alarm signal, drive subsequent conditioning circuit, the reference voltage that comparator circuit provides by contrast rheochord R P, relatively whether this signal is useful signal, if useful signal, then comparator circuit inputs to warning circuit with this alarm signal and drives the warning device warning, described delay circuit can be when human infrared signal disappears the people can keep the alarm state of 1min, notify the Security Personnel in time to come to check, avoid the generation of stealing, further heighten security performance, described warning circuit drives the diode displaying alarm position of described display circuit, improves antitheft efficient.
