Abstract
The invention discloses an Internet dynamic password unlocking management system, which mainly comprises a dynamic password electronic lock management system, a PDA identification recognition system and a dynamic password lock hardware system. The PDA identification recognition system is in wired/wireless connection with the dynamic password electronic lock management system. The dynamic password lock hardware system is in wired/wireless connection with the PDA identification recognition system. According to the technical scheme of the invention, people and locks are managed by the dynamic password electronic lock management system. When a person is assigned to unlock a lock, the identity of the person is authenticated firstly. Only people that have been recorded can pass the identity authentication. After that, the person is in connection and communication with the dynamic password electronic lock management system, and then the system receives a password to unlock the lock. Since the password is in the form of a one-off unlocking password, the safety of the lock is improved. Meanwhile, the unnecessary cost waste due to the password forgotten condition and the consequent forced unlocking operation can be eliminated.
Description
Technical field
The present invention relates to electric lockset field, specifically a kind of internet dynamic password is unblanked management system.
Background technology
Traditional mechanical latching is in following problem: lack switch record, can not pilot switch situation in real time, the licensing scheme of more not unblanking; Lack abnormal conditions warning system, do not have safety audit function, it has larger security risk at management aspect; Traditional password is easily lost or is forgotten, and when password cannot be changed in time, the long period uses fixing password, there is password leakage risk.
Because password is forgotten or mechanical code lock hardware fault, need the event opening safety cabinet by force of common occurrence.The operating process of change of secret code is comparatively loaded down with trivial details, and easy misoperation causes lock to use, and safety cabinet is closed the door and do not rotated lock collar and cause mechanical code lock not shut, and administrative center cannot from remote monitoring to the switch conditions of lock.
Summary of the invention
A kind of internet dynamic password is the object of the present invention is to provide to unblank management system, solve existing real-time pilot switch, the licensing scheme of unblanking is provided, safety audit function, solve the password that the determinacy due to password causes and reveal the potential safety hazard brought, solve effective problem of management that many locksets use simultaneously.
For achieving the above object, the invention provides following technical scheme:
A kind of internet dynamic password is unblanked management system, forms primarily of dynamic code electronic lock management system, PDA identification system and dynamic puzzle-lock hardware system; Described PDA identification system and dynamic code electronic lock management system are by wired connection or wireless connections, and described dynamic puzzle-lock hardware system is connected by wired or wireless with PDA identification system.
As the further scheme of the present invention: described dynamic code electronic lock management system is mounted in the management center server on computer, described PDA identification system is hand-held set or the mobile phone being provided with mobile phone A PP, and described dynamic puzzle-lock hardware system is dynamic password lock body hardware.
As the further scheme of the present invention: the number of described dynamic code electronic lock management system is one, and the number of described PDA identification system and described dynamic puzzle-lock hardware system is at least one.
As the further scheme of the present invention: its workflow is: management center server manages personnel and lockset; When management center server assigns a task, personnel assigned and unblank task time: the hand-held set first carried by personnel assigned or the mobile phone being provided with mobile phone A PP carry out authentication to personnel assigned; After authentication success, management center server by the hand-held set of dynamic password lock body hardware information, operating personnel or the mobile phone generating cipher being provided with mobile phone A PP, and sends it to the hand-held set of these operating personnel or is provided with on the mobile phone of mobile phone A PP; Password described in personnel assigned utilizes performs task of unblanking, and meanwhile, daily record of unblanking recorded by dynamic password lock body hardware; Personnel to be designated complete the task of unblanking, and the real needs according to management center server complete uploading of daily record of unblanking automatically, are and finish the work; That after finishing the work, detects daily record of unblanking uploads result, lockset state, and generates interlock code, and after everything is ready, management center server is waited for and assigned new task.
As the further scheme of the present invention: described password is disposable unlocking cipher, must be used by the people holding the hand-held set of specifying or the mobile phone being provided with mobile phone A PP; After terminating when time task of unblanking, namely described password cancels.
As the further scheme of the present invention: described in log recording of unblanking have the daily record of all tasks of unblanking, be convenient to check.
Compared with prior art, the invention has the beneficial effects as follows: the present invention manages the information of all dynamic password lock body hardware, hand-held set by dynamic code electronic lock management system or is provided with the information of mobile phone and operating personnel's information of mobile phone A PP; By personnel assigned and task of unblanking, the dynamic password lock body hardware specifically will opened can be assigned to concrete operating personnel, first to hand-held set or be provided with the cellphone information of mobile phone A PP and operating personnel's information manages, the hand-held set being only recorded in dynamic code electronic lock management system or the mobile phone being provided with mobile phone A PP and operating personnel just can be verified, and with dynamic code electronic lock management system connecting communication; Because password is disposable unlocking cipher, can not reuse, improve the security of lockset, and owing to being dynamic password, deposit and prevent password from revealing and the change of secret code frequently carried out without the need to carrying out recording, improve Password Management efficiency, reduce Password Management cost, can also eliminate because the unnecessary cost waste unblanking to cause by force brought forgotten by password.The invention solves existing real-time pilot switch, the licensing scheme of unblanking is provided, safety audit function, solve the password that the determinacy due to password causes and reveal the potential safety hazard brought, solve effective problem of management that many locksets use simultaneously.
