Abstract

Along with development of economy and progress of scientific technology, the anti-theft technology changes quickly, and a stealing means becomes more and more brilliant. According to the anti-theft door design scheme, a lock cylinder is formed by combining an electronic type structure and a mechanical type structure and has the advantages of the two modes, the defect that a mechanical type structure can be easily opened by a key and imitated is overcome, the anti-theft door system also has the advantages of high reliability and high safety of an electronic type lock, meanwhile, the anti-theft door system has good anti-explosion alarming capacity, and we believe that the design scheme has a certain promoting effect on development of the anti-theft door technology.

Description

There is the anti-theft door system of triple safe structure

Technical field

The present invention relates to a kind of anti-theft door system with triple safe structure, transformed the structure of lock core, utilized strain meter to devise antibomb unit, prevent using violent means to open the door and belong to security fields.

Background technology

At present, the theft in society is more and more savage, to important confidential data down to gold and silver property in theft target.When thief breaks through security system, security door seems particularly important as last line of defense.No matter be family or enterprises and institutions, the security door having a high security is all very necessary also have now a lot of design to security door. the security door scheme verifying that note key mode controls such as is sent with credit mobile phone; Based on the high reliability encryption Ic card security door controller of SLE4428; DSPTM $ 320VC5416 is used to devise the security door identifying fingerprint.But the design of these security doors is all very single, robber's door of pure electronic type is easily cracked, when some critical component is lost, such as mobile phone, Ic card etc., security door will be caused to have stolen danger.

Based on above-mentioned situation, the security door design scheme with blue heavy safeguard construction is proposed.

Summary of the invention

Opposite house is locked into has gone transformation, and make lock core have two-section mechanism, there is baffle plate centre, just can open baffle plate enter second segment lock when key is eligible.Key and door lock match, and often key has unique distinguishing mark, only have the key matched with door lock just can open gate, at security door built with automatic alarm system, and just can automatic alarm when external force makes security door produce deformation to a certain degree.

This anti-theft door system is divided into three unit, is lock core unit respectively, and intelligent-induction unit and antibomb unit, have triple safe structure, and the design scheme of each unit is as follows:

1, lock core unit: two-section structure. baffle plate

Lock core has done transformation on original basis, is divided into two by original lock core, and centre baffle plate cuts off lockhole, and baffle plate has self-locking device.The movement of baffle plate is subject to the control of two aspects, and one is the Electronic Control based on intelligent-induction unit controls signal, and two is Mechanical course of baffle plate lock core the last period.Only after intelligent-induction unit transmits control signal to baffle plate, the self-locking device of baffle plate unlocks, and now rotates key and baffle plate just can be made to remove. thus key enters next section smoothly.Do not have any effect there is no to rotate key in intelligent cell control signal situation.When key is extracted out from lockhole, baffle plate restores to the original state automatically.

2, intelligent-induction unit: launch and signal supervisory instrument

Key is built-in with IC-card, and built-in lock pin has the interface circuit of IC-card and single-chip microcomputer.Data in often key IC-card and the data in single-chip microcomputer internal memory have one-to-one relationship.When key inserts lockhole, internal data is sent to single-chip microcomputer by Ic card, these data compare with the data in internal memory by single-chip microcomputer, if conform to internal storage data, then single-chip microcomputer sends unlock command to baffle plate, if without these data in internal memory, then single-chip microcomputer keeps baffle plate self-locking state. send alarm signal simultaneously.In order to lawless person after preventing key loss finds the theft of key people room, once key loss, then immediately data corresponding in single-chip microcomputer are deleted, the key lost so just no longer can open security door.

3, antibomb unit: stress/deformation induction

Antibomb unit is made up of some strain ga(u)ges and power supply circuits.Strain ga(u)ge is the sensing element based on resistance one strain effect.Resistance one strain effect refers to the physical phenomenon that the resistance that box belongs to conductor changes when stressed generation distortion (elongating or shortening) of conductor.When metallic resistance silk is subject to axle business pulling force, its length increases and cross section diminishes, and causes resistance to increase.Otherwise, then cause resistance to reduce when it is subject to axial compression.Strain ga(u)ge can form multi-purpose resistance strain type sensor together with elastic sensing element, compensating resistance.Strain ga(u)ge can be divided into adhesive type, non-adhesive type, welded type by technique, jet printing type etc.

This unit adopts bended strain ga(u)ge, is attached to inside security door epidermis, and when attempting when there being external force to destroy security door, the strain meter at destroyed place produces deformation, and output voltage changes, after microprocessor detect to these changes, and trigger alarm signals.The design of strain meter will consider two aspect factors: one is likely can be caused strenuous vibration when security door shuts energetically thus cause deformation to a certain degree, two may cause when being and knocking at the door the place of knocking to produce trickle deformation, due to the device that strain meter is very sensitive, so the deformation caused of both of these case all can make single-chip microcomputer send alarm signal.

Detailed description of the invention

Along with expanding economy, the progress of science and technology, anti-theft technique makes rapid progress, and theft means are also more and more brilliant.The security door design scheme that native system proposes, lock core is that electronic type and mechanical type two kinds of structures combine, possesses the advantage of two kinds of modes simultaneously, both the easy key of mechanical structure had been overcome easily by the weakness of copying, there is again the feature of electronic type lock high reliability and high security, there is good anti-explosion alarming ability simultaneously, believe that the technical development of this design scheme to security door has certain facilitation.
