Lockset is a kind of product for protecting personal property, it is therefore intended that protection personal safety as well as the property safety and personal secrets. In increasingly complicated social security environment, the important screen of the security of the lives and property is ensured during functional, safe lockset Barrier.
Existing lockset generally comprises mechanical lock, Fingerprint Lock and coded lock, and mechanical lock utilizes the key and lock of dissimilar tooth form The cooperation of core is opened, but the tooth form of key can easily be duplicated, and the key of mechanical lock is easily lost, and no matter who is found Key can easily open lockset, cause the security of lockset to substantially reduce；Fingerprint Lock is led to using the uniqueness of mankind's fingerprint Optical fingerprint identification system is crossed to be identified fingerprint, but the False Rate of optical fingerprint identification system is higher, and make every time The fingerprint trace of user can be all left during with fingerprint on optical fingerprint identification system, and these fingerprint traces have what is be replicated Risk, additionally, the equipment that in the market occurs in that many manufacture fingerprint fingerprint, uses not safe enough for a user；And it is close The password of code lock is easy to be cracked or steals, and security is less high.
The content of the invention
It is an object of the invention to provide a kind of intelligent and safe lockset based on laser identification technology, it is possible to increase lockset Security, and strong security, not transreplication.
To achieve the above object, the present invention is adopted the following technical scheme that：
A kind of intelligent and safe lockset based on laser identification technology, including for launching the laser key and use of laser cryptogram signal In the lock core for opening lockset, the laser key is included for launching the laser emitting module of laser signal, for driving laser The drive module of transmitter module work, for the dynamic coding encrypting module that is encrypted to laser signal and for believing laser Number diversing lens for being collimated, the output end of the dynamic coding encrypting module is connected with the input of drive module, drives The output end of module is connected with the output end of laser emitting module, and the diversing lens are arranged at the front end of laser emitting module；
The lock core is including the receiving lens for receiving laser signal, for swashing that the laser signal to receiving is arranged Optical detection module, for the laser signal for receiving is identified signal identification module, for receive laser letter Number the dynamic coding deciphering module and mechanical lock that are decoded, receiving lens are arranged at the front end of laser acquisition module, laser The output end of detecting module is connected with the input of signal identification module, and output end and the dynamic coding of signal identification module are decrypted The input of module is connected, and the output end of dynamic coding deciphering module is connected with mechanical lock；
The drive module control laser emitting module transmitting laser signal, the emitted lens of laser signal are launched, are received After lens receive laser code signal, then arranged through laser acquisition module, then by signal identification module to arranging it Laser code afterwards is identified, and is finally authenticated by dynamic coding deciphering module, if laser key matches, is locked Core is opened.
The laser acquisition module include be sequentially connected photodiode, sample resistance, Dolby circuit, amplifying circuit and Shaping circuit, the output end of shaping circuit is connected with signal identification module.
The lock core also includes state recognition module and WIFI module, and state recognition module is connected with mechanical lock, state The output end of identification module connects remote equipment through WIFI module.
The diversing lens and receiving lens use convex lens.
The laser key also includes power module, and power module is connected with drive module.
The invention has the advantages that：
（1）Be introduced into laser identification technology in conventional lock by the present invention, and standard machinery key, profit are replaced using laser transmitting set Replace mechanical lock with laser receiving set, prevent lockset from being invaded using the confidentiality and non-reproduction of laser signal Or crack, improve safety and reliability of the invention；
（2）Equipped with diversing lens, diversing lens can reduce the dispersion angle of laser signal to laser key, improve laser signal Power density, be easy to laser acquisition module to receive enough laser energies, meanwhile, by the hair for reducing laser signal Dissipate angle, it is possible to increase the security and anti-copying of lockset；Equipped with receiving lens on lock core, receiving lens can increase sharp The optical gain of optical detection module, improves the receiving sensitivity of equipment, meanwhile, the reception that receiving lens can limit lock core is regarded , it is ensured that what lockset was received is the laser of laser key transmitting, prevents other laser signals from being interfered to lock core, improves this The security and reliability of invention；
（3）Dolby circuit is provided with laser acquisition module, noise signal is suppressed using Dolby circuit, improved laser and visit Survey module sensitivity, therefore laser key transmitting laser signal power it is very low when laser signal can also be known Not, so as to improve recognition capability of the laser acquisition module to weak laser signal, the sensitivity of laser acquisition is improved；Further, since The power of the laser of laser key transmitting is relatively low, general laser detector faint laser signal not easy to identify, therefore this Invention has certain anti-copying；
（4）The present invention is decrypted using dynamic encryption technology to the dynamic password that laser key sends, and is come according to this to laser Key is verified, because dynamic password has dynamic and randomness, can all produce a new dynamic close when unlocking every time Code, due to this dynamic password be it is random, it is irregular to follow, so it is difficult to the software that is cracked is cracked, dynamic password is using once Can not be continuing with afterwards, prevent dynamic password in transmitting procedure or leaked when password is input into, further, since dynamic is close Code is difficult to crack, and dynamic password is change at random, will be changed before password is decrypted, therefore, even if swashing Optical signal is replicated, and dynamic password can not be cracked, and further improves safety and reliability of the invention；
（5）Lock core also includes WIFI modules, and the state of lockset can be counted, recorded and be uploaded to network by WIFI module, on Level security data center can learn the state of lockset by network；Simultaneously when lockset is under attack or destroys, lockset can Security alarm is carried out with superior secure data center, security of the invention is improved；
（6）Additionally, WIFI module and the relatively independent work of dynamic decoder deciphering module, WIFI module is only capable of the shape to mechanical lock State is read out and mechanical lock can not be operated, and WIFI network can so be kept apart with laser identification, prevents from leading to Cross WIFI module and read laser code signal, it is ensured that the safety and reliability of laser code signal.
Simple structure of the present invention, can not only improve the security of lockset, and strong security, not transreplication.
