Abstract

The utility model relates to an antitheft product, and more specially is an intelligent antitheft door. The utility model comprises a mechanical antitheft door and various sensors which are arranged in a door plate. The utility model can check various signals that illegal intruders break the intelligent antitheft door, the various signals are processed by a microprocessor, the one-site whistle is sent out, the remote alarm function is started, the illegal intruders are deterred, and thus the loss is avoided. As the installation and the use are same with the mechanical antitheft door, the utility model is widely used for places of residential districts, offices, etc.

Description

Intelligent anti-theft door

Technical theme

The utility model relates to a kind of anti-theft product, a kind of specifically intelligent anti-theft door, and it can be widely used in family, office and office premises.

Technical background

Existing security door, the overwhelming majority is engineering goods, is a frame all around, interior welding steel plate or round steel are loaded onto mechanical lock.Its advantage is that technology is simple, and is easy to make, therefore uses extensively; Its defective is to lack on-the-spot and the remote alarms function, so can not in time stop and arrest criminal, causes damage to enterprise.

Goal of the invention

The utility model purpose provides a kind of intelligent anti-theft door, it can guarantee that legal user normally uses, and when by illegal the unlatching (as: flame cuts, hits sled etc.), police whistle sound can be sent in the scene, deterrence illegal invasion person can be sent to warning message on the police and owner's the communication tool simultaneously.Technical scheme

Concrete structure of the present utility model is: adopt qualified steel processing doorframe, the outside is welded on the doorframe with door-plate, and load onto automatically controlled parts such as travel switch, temperature detect switch (TDS), piezoelectric ceramic piece, printed circuit board, the door-plate of the inside is screwed on doorframe again, forms the intelligent anti-theft door of electromechanical integrated structure.The utility model operating principle:

1, put the police: owner leaves home to lock a door, circle control shape dead bolt puts in the doorframe, and this moment, the block of dead bolt bottom unclamped travel switch, and the signal of telecommunication of travel switch then passes on the microprocessor on the printed circuit board, send a group coding signal by microprocessor control, warning system is placed the state of alert.

2, remove the police: when normally opening in the dead bolt indentation door, baffle plate clamping stroke switch, the travel switch state variation, the output signal of telecommunication is launched a group coding signal at stop warning system to microprocessor by microprocessor control radiating circuit.

3, crashproof sled: putting under the alert situation, when intelligent anti-theft door is subjected to clashing into, piezoelectric ceramics just sends the corresponding signal of telecommunication, microprocessor receives that controlling the onsite alarming circuit sends police whistle sound on the one hand behind this signal, controls radiating circuit on the other hand and launches group coding alarm signal startup remote alarms.

4, flame cutting: temperature sensor adopts some normally closed type temperature detect switch (TDS)s to be connected in series.Putting under the alert situation, criminal is if cut intelligent anti-theft door with flame, when temperature reaches one regularly, the temperature detect switch (TDS) automatic disconnection, temperature detect switch (TDS) disconnects current potential is changed, and microprocessor detects potential change, just controls the reaction that onsite alarming circuit and radiating circuit are made warning respectively.

When criminal sawed intelligent anti-theft door with a chainsaw, the electric wire in always breaking because electric wire is broken, was equivalent to temperature detect switch (TDS) and disconnects, and also can report to the police.

Figure of description

Accompanying drawing 1 is the utility model structural representation, and accompanying drawing 2 is an electric control schematic diagram, and accompanying drawing 3 is the mounting structure schematic diagram.

Number in the figure 1 is a block, and 2 is travel switch, and 3 is transmitting antenna, and 4 is temperature detect switch (TDS), and 5 is automatically controlled printed substrate, and 6 is battery, and 7 is piezoelectric ceramics, and 8 is lead, and 9 is dead bolt, and 10 is music door-bell, and 11 is doorframe, and 12 is door-plate.

Specific embodiments

With reference to Figure of description 1, make doorframe 11 and door-plate 12, door-plate is welded on the doorframe, door-plate top is by putting dead bolt and music door-bell outside;

With reference to Figure of description 2, make automatically controlled printed substrate, choose microprocessor 87LPC762, crystal oscillator OSC1 and OSC2, integrated package of pressure-stabilizing U1, be HT7150, power switch pipe U2 is that D123 and suitable specification triode, resistance, capacitor and inductor and miniature transmitting antenna connect and debug, and every limit is 3 about choosing 6 temperature detect switch (TDS)s and being, and staggers up and down, be screwed on riveting nut, make its metal shell be close to door-plate.Piezoelectric ceramics is adhesive on the door-plate with pulling force.

Claims

1, a kind of intelligent anti-theft door, it comprises doorframe and door-plate, its feature just is that the door-plate inboard is provided with temperature detect switch (TDS), piezoelectric ceramics and automatically controlled circuit board.

2, a kind of intelligent anti-theft door according to claim 1 is characterized in automatically controlled circuit board when being subjected to sensor signal, and can send on-the-spot police whistle sound and while can the wireless remote-controlled alarm system works.
