Abstract
With the development of economy and progress of science and technology, the security technology changes with each passing day and the stealing means becomes more sophisticated. The invention provides a security door system. A lock cylinder is the combination of the electronic type structure and the mechanical type structure, so that the security door system integrates the advantages of the electronic type structure and the mechanical type structure, not only overcomes the shortcoming that a key is easily counterfeited in the mechanical structure, but also has the advantages of high reliability and high safety of an electronic type lock, has the good anti-explosion warning capacity, and plays a role in promoting the technological development of security doors.
Description
Technical field
The present invention relates to a kind of anti-theft door system with triple safe structure, transformed the structure of lock core, utilize strain meter to design antibomb unit, prevent from 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, steals in target to important confidential data down to gold and silver property.In the time that 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 that has high security is all very necessary a lot of designs to security door that now also have. such as send the security door scheme of checking note key mode control with credit mobile phone; High reliability based on SLE4428 is encrypted Ic card security door controller; Use DSP TM $ 320VC5416 to design the security door of identification fingerprint.But the design of these security doors is all very single, robber's door of pure electronic type is easily cracked, and in the time that some critical component is lost, such as mobile phone, Ic card etc. will cause security door to have stolen danger.
Based on above-mentioned situation, propose to have the security door design scheme of blue heavy safeguard construction.
Summary of the invention
Opposite house is locked into has gone transformation, makes lock core have two-section mechanism, and there is baffle plate centre, just can open baffle plate and enter second segment lock in the time that key is eligible.Key and door lock match, and every key has unique distinguishing mark, only have the key matching with door lock just can open gate, and automatic alarm system is housed in security door, just can automatic alarm in the time that external force makes security door produce deformation to a certain degree.
This anti-theft door system is divided into three unit, is respectively lock core unit, 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 been done transformation on original basis, and original lock core is divided into two, and centre cuts off lockhole with baffle plate, and baffle plate has self-locking device.The movement of baffle plate is subject to the control of two aspects, and the one, based on the Electronic Control of intelligent-induction unit controls signal, the 2nd, the machinery control of baffle plate lock core the last period.Only, after intelligent-induction unit transmits control signal to baffle plate, the self-locking device release of baffle plate, just can make baffle plate remove thereby now rotate key. and key enters next section smoothly.Do not have any effect there is no to rotate key in intelligent cell control signal situation.In the time that key is extracted out from lockhole, baffle plate restores to the original state automatically.
2, intelligent-induction unit: transmitting 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 data and single-chip microcomputer internal memory in every key IC-card have one-to-one relationship.In the time that key inserts lockhole, internal data is sent to single-chip microcomputer by Ic card, single-chip microcomputer is by the data comparison in these data and internal memory, if conform to internal storage data, single-chip microcomputer sends unlock command to baffle plate, if, without these data, single-chip microcomputer keeps baffle plate self-locking state in internal memory. send alarm signal simultaneously.For lawless person after preventing key loss finds the theft of key people chamber, once key loss is deleted data corresponding in single-chip microcomputer immediately, the key of losing so just no longer can have been opened 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 resistance that box belongs to conductor changes in the time of the stressed generation distortion of conductor (elongating or shortening).In the time that metallic resistance silk is subject to axle business pulling force, its length increases and cross section diminishes, and causes that resistance increases.Otherwise, in the time that it is subject to axial compression, cause resistance to reduce.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, jet printing type etc. by technique.
This unit adopts bended strain ga(u)ge, is attached to security door epidermis inner side, and in the time having external force to attempt to destroy security door, the strain meter at destroyed place produces deformation, and output voltage changes, and single-chip microcomputer detects after these variations, trigger alarm signal.The design of strain meter will be considered two aspect factors: the one, thus in the time that being shut energetically, security door likely can cause strenuous vibration to cause deformation to a certain degree, the 2nd, while knocking at the door, may cause the place of knocking to produce trickle deformation, because strain meter is very sensitive device, so the deformation causing of both of these case all can make single-chip microcomputer send alarm signal.
The specific embodiment
Opposite house is locked into has gone transformation, makes lock core have two-section mechanism, and there is baffle plate centre, just can open baffle plate and enter second segment lock in the time that key is eligible.Key and door lock match, and every key has unique distinguishing mark, only have the key matching with door lock just can open gate, and automatic alarm system is housed in security door, just can automatic alarm in the time that external force makes security door produce deformation to a certain degree.
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 two kinds of structures of mechanical type combine, possesses the advantage of two kinds of modes simultaneously, both overcome the weakness that the easy key of mechanical structure is easily copied, there is again the feature of electronic type lock high reliability and high security, there is good anti-explosion alarming ability simultaneously, believe that this design scheme has certain facilitation to the technical development of security door.
