Abstract
The burglar alarm consists of theft-defence warning net and sensitive broken-circuit theft-defence alarm connected together. The sensitive broken-circuit theft-defence warning circuit is triggered by broken circuit or body's inductance to send out acoustic and optical alarm signals. The theft-defence warning net is set by using wire with or without shielding layer around the defence area. Compared with available technology, the burglar alarm has the features of reasonable design, high sensitivity, low false alarm rate and others.
Description
The present invention relates to the safety alarm device in a kind of house, courtyard or the security area, specifically a kind of network-type sensitive broken-circuit barglar alarm.
Burglar alarm is widely used in the fields such as warehouse, bank, office space, place of military importance and home dwelling.The kind of present known burglar alarm is mainly sound, light two big classes, for providing the sensing form of trigger pip, sound and light alarm is divided into contact, photo-electric and induction type again, photo-electric is mainly used the far infrared sensor, its advantage is highly sensitive, its deficiency be to use that cost height, rate of false alarm height, fence coverage are little, the far infrared sensor is difficult for hidden etc.The advantage of inductosyn is highly sensitive, but rate of false alarm is higher, and for example the induction type of installing on some motorcycle is put robber's alarm, reports to the police as long as there is the people to walk accessible triggering, has increased injurious noise to environment virtually.Contact is that deficiency that the closure by the contact provides alerting signal in use to exist for warning circuit provides alerting signal or circuit to be broken as warning circuit is that the thief can escape closing of contact sensor or will cut off with the lead that sensor joins and makes closing of contact faulty sensor, the deficiency that the line broken circuit sensor in use exists is that the thief can couple together with a section lead and makes its short circuit being located at alerting signal transducer wire in the security area, and then the warning transducer wire cut off, thereby make equally that alarm is malfunctioning to lose the warning effect of stealing of putting.
The purpose of this invention is to provide the compound network-type sensitive broken-circuit barglar alarm that alerting signal is provided for warning circuit of a kind of line broken circuit signal and induced signal.
The objective of the invention is to realize in the following manner, the two-wire cable that adopts band screen abutment line is as opening circuit, induction alarm sensing lead, this alerting signal transducer wire is woven into the burglar alarm net is arranged on door, window, the roof, in wall or the security area, or be made into the theftproof alarm glass of special-purpose anti-theft alarm lock of band alerting signal transducer wire or band alerting signal transducer wire, as long as the thief is when passing through the net formula security area that is provided with the alerting signal transducer wire, or destroy when being provided with alerting signal transducer wire anti-theft alarm lock, no matter which kind of mode of employing, as long as the alerting signal transducer wire is opened circuit, burglar alarm just can receive breaking alarming signal and induction alarm signal simultaneously, produce continual sound and light alarm, till the Security Services turns off power supply.
Accompanying drawing is the electrical block diagram of network-type sensitive broken-circuit barglar alarm.
Below with reference to Figure of description network-type sensitive broken-circuit barglar alarm of the present invention being done Explain.
Network-type sensitive broken-circuit barglar alarm of the present invention, its structure is by antitheft warning network And the high sensitivity burglar alarm that opens circuit consists of, antitheft warning network and the high sensitivity burglar alarm that opens circuit Device joins, by opening circuit or human body sensing is sent out the high sensitivity anti-theft warning circuit triggering and conducting that opens circuit The visual alarm of speaking, antitheft warning network are with grid with the lead of band screen abutment line or plain conductor Form is arranged on around the zone that needs burglar alarm.
The burglar alarm net is band to be shielded lead or the plain conductor horizontal stroke or the vertical setting of types row of abutment line or interweaves anyhow be arranged in door, window, roof, the body of wall, or with the compound composition fence of conventional entanglement, burglar alarm net and the high sensitivity burglar alarm that opens circuit is connected to form burglar alarm.
The burglar alarm net can conducting film form make lead attached to constituting the burglar alarm net on the door glass, this burglar alarm net and the high sensitivity antitheft newspaper that opens circuit is connected to form burglar alarm.
The high sensitivity burglar alarm that opens circuit is to be made of induced signal amplifying circuit A, chopping signal amplifying circuit B and sound light alarming circuit C, and induced signal amplifying circuit A is by triode T
