Abstract

The invention relates to a novel combined monitoring intelligent alarm system for a burglar-proof door, which mainly comprises a vibrating sensor 1, human body approaching sensors 5 and 7, a photoelectric sensor 4, a key with an RF card 9, a card reader 6, an information processing module 2, an alarm output module 8 and the like. When the system is in the monitoring state, the vibrating sensor, the human body approaching sensors, the photoelectric sensor and the like and the RF card reader perform combined type monitoring on disturbance information received by the burglar-proof door; when someone unlock and destroy the burglar-proof door or a lockset by using an unauthorized key or an unauthorized tool, the alarm output module 8 sends an alarm signal; and when someone open the door outdoors or indoors by using the authorized key with the RF card 9, the alarm output module 8 shuts off automatically. An anti-theft alarm system which has the advantages of sensitive monitoring, accurate and timely alarming, low false-alarm rate and simple and convenient operation and installation is provided by adopting the modern information processing technology, so that the anti-theft capability of the burglar-proof door can be improved obviously.

Description

A kind of novel combined monitoring intelligent alarm system for burglar-proof door

Technical field: the present invention relates to a kind of novel combined monitoring intelligent alarm system for burglar-proof door.

Background technology: the measures such as theftproof performance of present antitheft door by increasing steel plate thickness and bolt number, improving lock core is difficult to the theft means that effectively antagonism is forced open the door and entered the room; The monitoring mode of existing burglar alarm is in modes such as infrared, door status switchs, exist to report to the police unreliable (the easy crested of Passive Infrared Sensor), alert false alarm rate height, warning lag behind (force open the door enter the room then could report to the police), use deficiencies such as inconvenience (switch is all by artificial setting at every turn), installation inconvenience opportunity, influences anti-theft effect.

Summary of the invention: this system is intended to use the present information treatment technology, a kind of sensitive monitoring is provided, reports to the police accurately and timely, false alarm rate is low, operation easy-to-install intelligent alarm system, to significantly improve the anti-theft capability of antitheft door.

Technical solution of the present invention is: native system partly is made up of the key of vibration transducer, human body proximity sensor, photoelectric sensor, band RF card, RF card reader, message processing module, alarm output module etc.It is characterized in that: on door lock, increase an oblique dead bolt, with the open/close state of its special detection door.This system is in the start monitoring state all the time under the antitheft door closed condition.When (prizing) antitheft door or lockset are unblanked, destroyed to the undelegated key of human or other instruments, alarm output module was sent alerting signal.When the key with the band RF card of having authorized opened the door, alarm output module was closed automatically; When opening the door within doors, alarm output module is closed automatically.

The invention will be further described below in conjunction with the drawings and specific embodiments.

Fig. 1 is the scheme of installation of native system on antitheft door.

Fig. 2 is the Key structure synoptic diagram of band RF card.

Fig. 3 is the scheme of installation of photoelectric sensor on lock core.

As shown in Figure 1, when door was in closed condition, 3. system was compressed by the oblique dead bolt that 4. photoelectric sensor detects on the lockset, and system enters monitoring state automatically.

As shown in Figure 1,7. 1. vibration transducer form a compound sensor array with the human body proximity sensor that is installed in outer side of door, when the antitheft door outside has that the people forces open the door, during picking lock, 7. 1. shock sensor will receive signal simultaneously with human body proximity sensor, when composite signal surpassed the thresholding of procedure stipulation and time, 2. message processing module drove alarm output module and 8. sends alerting signal.For simple vibrations signals such as (as fitting up vibrations etc.), system does not report to the police, and therefore, can effectively eliminate false-alarm.

As shown in Figure 2,10. the RF card is connected as a single entity with the afterbody of key, the key that forms band RF card 9..6. this key is authorized by the card reader of the antitheft door of correspondence.As shown in Figure 1, when 9. opening the door with this key, 6. the RF card reader that is installed in the antitheft door outside detects the RF card information in the key when key inserts keyhole, and 2. processing module closes alarm output module, but with this key normal door.

As shown in Figure 3, at this lock pin

Go up and make a call to a hole

Photoelectric sensor is installed at the two ends in hole

Insert keyhole as key or unlocking tool The time photosignal be blocked, 2. message processing module passes through photoelectric sensor

Detect this signal.For undelegated key or other instruments, 2. message processing module drives alarm output module and 8. sends alerting signal.

As shown in Figure 1, at antitheft door installed inside human body proximity sensor 5., when owner when opening the door within doors, this sensor detects human body signal, 2. message processing module closes alarm output module, but normal door.

Claims

1. novel combined monitoring intelligent alarm system for burglar-proof door.Partly form by the key of vibration transducer, human body proximity sensor, photoelectric sensor, band RF card, RF card reader, alarm output module etc.It is characterized in that: on door lock, increase an oblique dead bolt, with the open/close state of its special detection door.This warning system is at antitheft door and enters monitoring state when closing, and when antitheft door or lockset are unblanked, destroyed to the undelegated key of human or other instruments, alarm output module was sent alerting signal.When the key with the band RF card of having authorized opens the door, system's automatic closing and alarm output module; When opening the door within doors, system is with the automatic closing and alarm output module.

2. as claims 1 described combined monitoring intelligent alarm system for burglar-proof door, it is characterized in that: on door lock, increase an oblique dead bolt, with the open/close state of its special detection door.

3. as claims 1 described combined monitoring intelligent alarm system for burglar-proof door, it is characterized in that: form the compound sensor array by vibration transducer and human body proximity sensor, various disturbances such as forcing open the door of being subjected to of antitheft door, picking lock are monitored; Message processing module is to carrying out overall treatment, analyze and judge from key elements such as the kind of compound sensor array signal, size, time relationships, have the people illegally unblanking outdoors, picking lock, sending alerting signal when situation such as forcing open the door when its signal of judgement belongs to.

4. as claims 1 described combined monitoring intelligent alarm system for burglar-proof door, it is characterized in that: the afterbody of RF card and key is connected as a single entity, forms the key of band RF card, this RF card is by the card reader mandate of the antitheft door of correspondence.When opening the door with this key, the RF card reader that is installed in the safe-guard door lock outside detects the RF card of mandate, the automatic closing and alarm output module, but with this key normal door.
