Abstract

The utility model relates to an intelligent anti-theft alarm, composed of a single-chip microcomputer (or a computer), a lock and switches. The lock is provided with two switches which are respectively arranged between a lock body and a lock bolt and a locking box and the lock bolt; the lock bolt serves as a common movable contact piece of the two switches; the logic input of the switches is identified by the single-chip microcomputer (or the computer). The utility model can monitor an entire residential district comprising banks, office buildings, etc. by being combined with programs in a wired intelligent mode; once the lock is prized by someone, the intelligent anti-theft alarm can alarm and display a stolen door number. The utility model has the advantages of low cost, big capacity, safety and strong ability of bringing onto load.

Description

Intelligent anti-theft alarm

The utility model belongs to warning device, relates in particular to a kind of intelligent burglar alarm.

Existing anti-theft product can be divided into several types such as switching mode, infrared type, wireless transmit type.What wherein have should not promote because complex structure, cost are high, and the technological means that can adopt that has makes it malfunctioning, thereby does not reach antitheft purpose.And existing anti-theft product is monomer-type as antitheft door, theftproof lock etc., can not carry out the anti-theft protection of colony.

The purpose of this utility model is to overcome the deficiency of prior art, and a kind of intelligent burglar alarm is provided, and is a kind of anti-theft device that can carry out colony's protection to objects such as residential area, bank, warehouses.

Technical solution of the present utility model is: existing lock is improved, two parallel connection type switches have been set up therein, be located at respectively between lock body and dead bolt, keeper and dead bolt, parallel branch one termination single-chip microcomputer (or computing machine) input interface of two switches, the other end connects single-chip microcomputer (or computing machine) output interface or ground wire.The input of the logic of two switches can monitor many locks in conjunction with designing program for single-chip microcomputer identification, with the family that shows stolen family number, and gives the alarm.

The utility model has adopted the scanning technique of micro computer, can monitor alert whole residential area in the wired intellective mode with a single-chip microcomputer or computing machine, comprise bank, office building etc., still can work as usual during power failure, and have that cost is low, capacity is big, safe and reliable, characteristics that carrying load ability is strong.

Accompanying drawing 1: be structural representation of the present utility model.

1 lock body, 2 dead bolts, 3 keepers, 4 oblique tongues

5 fixed touching plates, 6 springs, 7 frameworks

Below the contrast accompanying drawing is elaborated to the utility model in conjunction with the embodiments.

The utility model is respectively equipped with K switch 1, K2 at lock body 1 and 2 of dead bolts,

keeper

3 and 2 of the dead bolts of existing lock, the movable contact spring of K switch 1, K2 is dead bolt 2, two fixed touching plates 5 are located at the end of lock body 1, keeper 3 respectively by framework 7, and with dead bolt 2 at same horizontal line, 5 of framework 7 and fixed touching plates are provided with spring 6, when guaranteeing to lock a door or turn the key in the lock, there is one to contact with dead bolt 2 all the time in two fixed touching plates 5, promptly there is one among K switch 1, the K2 and locates closure state.5 of two fixed touching plates of K switch 1, K2 are communicated with a lead and are connected to single-chip microcomputer (or computing machine) input interface, movable contact spring is connected to single-chip microcomputer (or computing machine) output interface or ground wire by lead, utilizes single-chip microcomputer (or computing machine) to monitor some locks.

Single-chip microcomputer (or computing machine) scans every lock, and when scanning when its logic is input as " 0 ", alarm is not reported to the police, and when scanning " 1 ", by program, memory this room number is down also sent warning, and shows stolen family number.

When locking the door, dead bolt 2 enters in the keeper 3, and at this moment, K switch 1 disconnects, and K switch 2 closures are input as " 0 " to the logic of single-chip microcomputer (or computing machine), do not report to the police; When turning the key in the lock, dead bolt 2 is retracted into lock body 1, K switch 1 closure, and K switch 2 disconnects, and is " 0 " still to the logic input of single-chip microcomputer (or computing machine), does not also report to the police.When the people pried open door by force or rushes open, dead bolt 2 was deviate from from keeper 3, and K switch 2 disconnects, thereby makes K switch 1, K2 all locate off-state, and the logic input of single-chip microcomputer (or computing machine) is become " 1 ", and alarm equipment alarm also shows stolen family number.Even when someone cuts off line and forces open the door, still be " 1 " to the logic input of single-chip microcomputer, alarm still can report to the police and show by beneficial family number.

Claims

1, a kind of intelligent antitheft newspaper device, constitute by single-chip microcomputer (or computing machine), lock and switch, it is characterized in that: be provided with termination single-chip microcomputer (or computing machine) input interface of parallel connection type K switch 1, K2, K switch 1, K2 parallel branch, another termination output interface or ground wire at lock body 1 and dead bolt 2, keeper 3 and 2 of dead bolts.

2, alarm according to claim 1 is characterized in that: the movable contact spring of K switch 1, K2 is dead bolt 2, two fixed touching plates 5 and is located at the end of lock body 1, keeper 2 respectively by framework 7, and with dead bolt 2 on same horizontal line.

3, alarm according to claim 2 is characterized in that: 7 of fixed touching plate 5 and frameworks are provided with spring 6.
