Description

Theft-proof computer controlled alarm built-in lock

The utility model belongs to a kind of door lock alarm, can be used on the built-in lock of door.

The stolen problem of current resident family happens occasionally, and causes stolen reason, and majority is that the unreasonable structure or the mechanical strength of door and lock is not enough, stealer is forced open the door press lock to succeed, and forces open the door, and the stealer that also has has obtained key burglary easily in advance.Press lock in order to prevent to force open the door, the structure and the intensity of manufacturer's opposite house, lock are done significant improvement, find that through looking into patent gazette many patents that alarm is installed are also arranged on door or door lock, in case unconventional opening the door just reported to the police.But produce the patent of reporting to the police, preventing key loss in the key nest for being retained at the back key that opens the door, do not find as yet, and thisly forget that the thing of taking out key still is recurrent, long slightly key of time is just taken away by the people easily, under the table send back to after perhaps being copied by the people, this just stays stolen hidden danger, and is very dangerous.

The purpose of this utility model is a kind of electronic control circuit of design, in the time of in key is retained in the key nest, can send the computer prompting burglar alarm built-in lock of alarm signal continuously.

The utility model computer prompting burglar alarm built-in lock comprises radiating circuit, receiving circuit, amplifying circuit, loudspeaker, power supply and power switch, the first warning circuit that it is characterized in that adopting KD1 series language integrated package and continuous piezoelectric ceramics MS thereof to constitute; The delayed alarm circuit that amplifying circuit, KD2 series language integrated package, power amplifier and the loudspeaker that has adopted delay circuit and back thereof to link to each other successively constitutes; Adopted and comprised delayed alarm circuit, with the time base circuit IC(that links to each other successively in KD2 back time-delay 15 seconds), cryptochannel SAO and the coding circuit KD-12E that is subjected to SAO control, radiating circuit, receiving circuit, decoding circuit KD-12D also comprise the receiving signal amplifier that links to each other with decoding circuit KD-12D and are subjected to the received signal warning circuit of this amplifier control and the Display and Alarm Circuit that display alarm board constitutes;

Power switch is mounted on the built-in lock.

Delay circuit is connected to form by triode BG1, BG2, resistance R 1, capacitor C 1, diode D2; Amplifying circuit is connected to form by triode BG3, BG4, BG5.

Cryptochannel SAO is made up of BG8, the direct-coupled switching amplifier of BG9 two-stage and coupled relay J 1, the contact J1-1 control radiating circuit on/off of relay J 1.

Coding circuit KD-12E has five bit address sign indicating numbers (D9-D13), with wherein three compositions are subscriber-coded, but 10,000 Subscriber Numbers of five bit address sign indicating number permutation and combination.The KD-12D of decoding circuit also is five bit address sign indicating numbers (D19-D23), the address code of coding circuit address and decoding circuit in correspondence with each other, connected mode is too.

Receiving signal amplifier is made up of integrated package KD4 and relay J 2, and its input OVT1 links to each other with the output OVT of decoding circuit.Contact J2-1, the J2-2 of relay J 2 controls the light on and off of display lamp on the display alarm board and the work of received signal warning circuit respectively.

Display alarm board is made up of the contact of resident family's number, display lamp and relay J 2.The received signal warning circuit is made up of the contact of integrated package KD5, power amplification circuit, loudspeaker and J2.

Power switch is mounted on the fuse of a built-in lock, pellet shot from a slingshot in lock core has a long-neck, spring housing is on long-neck, long-neck stretches out lock core outside and links to each other with the spring contact of power switch XW, when key inserts in the key nest, the extruding pellet shot from a slingshot is moving to the guest performer, and power switch two contacts are linked to each other, and connects power supply.A, B are the prap of power switch.

The relative position of two contacts of spring sensors A BD is fixed, a bell-jar contact outside, another the band spring the contact contact place bell-jar contact inside, two contacts do not contact under the normal condition.This sensor is fixed on the inboard of door, when the people hits, because vibration makes the contact of sensor two contacts, connects power supply, and chimes of doom is sent in triode BG3, BG4, BG5, KD2 work.If when making the sensor vibration, can press the KS button immediately because of misoperation, can false alarm.

The electronic circuit of computer prompting burglar alarm built-in lock, comprise that coding circuit and radiating circuit are installed in the inboard of user's door, and receiving circuit, receiving signal amplifier, received signal warning circuit and decoding circuit are installed in the back of display alarm board, resident family's number and display lamp are housed on the display alarm board, and display alarm board is located at the central part of residential quarters.

The advantage of the utility model computer prompting anti-theft built-in lock is:

1, circuit design is more reasonable, can realize repeatedly reporting to the police, and after twice audible alarm, just reports to the police the theftproof performance height once more by display alarm board as taking key not yet away.

2, multiple functional, easy to use, surpassed for 30 seconds if there is the false key of human to open the door, promptly report to the police, force open the door, hit door as the people and also send chimes of doom, the button KN that calls at the door is being housed outdoors, illuminating lamp button KA above the key.
