Abstract

The invention provides a method for automatically coding a user number of a fingerprint lock, which comprises the following steps that: each user in a fingerprint lock is marked by a user number, each user number has two statuses, i.e. available and used, when a system utilizes the user number, the status is recorded, when the available user number is required to be used, the status of the user number is searched, the available user position which is discovered at first is found out and is coded into a corresponding user number, and the available user number is returned; and when the used user number is required, the status of the user number is searched, the position of the used user number which is discovered at first is found out and is automatically coded into a user number, and the used user number is returned. The method has the advantages that the user number is automatically managed, the user is free from remembering the user number when utilizing the user number, and the available user number is automatically found to be registered and deleted, so the user can conveniently and easily use the fingerprint lock.

Description

A kind of method of automatically coding user number of fingerprint lock

Technical field

The present invention relates to that the user accesses to your password and the system that logins of user name in field that user name is numbered, in particularly a kind of Fingerprint Lock, Customs Assigned Number is carried out the method for automatic coding.

Background technology

Fingerprint Lock is a kind of electronic intelligent lock that carries out switch lock by fingerprint.Everyone comprises that the skin lines of fingerprint has nothing in common with each other, and presents uniqueness and constant throughout one's life on pattern, breakpoint and point of crossing.In view of the above, we just can be mapped a people with his fingerprint, compare by the finger print data with his fingerprint and preservation in advance, just can verify its true identity.Figure 1 shows that a kind of system chart of Fingerprint Lock, Fingerprint Lock comprises the sensor and the circuit peripheral circuit 2 thereof of fingerprint image acquisition, the digital signal processor DSP 1 of fingerprint algorithm, also has power supply in the peripheral circuit of DSP1, the storer 7 of clock and DSP and controller and motor-drive circuit 6, controller mainly contains processor 3 and peripheral circuit, mainly contain power circuit in the peripheral circuit of processor, clock circuit and controller storage 8, keyboard 4, hummer 9 and the charactron 5 that is used for showing etc., during use, after receiving fingerprint signal, fingerprint sensor 2 is input in the DSP1, in DSP1, carry out the information of computing acquisition fingerprint, be input in the controller by the UART communication interface, in controller, 3 couples of users' of processor finger print information is compared with the biology record that is stored in wherein, if correctly indication motor driving circuit 6 unblank, otherwise do not open.The original management of Fingerprint Lock to user number, just labor management is at every turn the typing user, during the deletion user, all be manually to import user number, to the user number management, very weak like this, if, the user, during typing, typing No. 1 user, No. 4 users, if the user does not keep a record, these No. 2, No. 3 the user is difficult to be employed, and also has the certain user to walk, after the deletion,, after the deletion, as do not keep a record if be No. 54 users, to be difficult to by usefulness, when particularly number of users is very big, manage more difficult.If, during the deletion user, as fail user's typing situation is kept a record, will not know which user number has fingerprint, password need be deleted, for the user number management has brought problem.

Summary of the invention

Be to solve the problem of user number management in the Fingerprint Lock, the present invention has designed the user number automatic coding, automatically leading subscriber number.

The present invention in order to realize the technical scheme that its goal of the invention adopts is: a kind of method of automatically coding user number of fingerprint lock, each user is identified by user number in the Fingerprint Lock, each user number all has available, has been used two states, when system uses user number, note these states, when needs use available subscribers, search for these user number states, find out the available customer location of finding at first, and be encoded into corresponding user number, return available subscribers number; When user number that needs have used, search for these user number states, find out the user number position of having used of discovery at first, and automatic coding becomes user number, return and use user number.

Characteristics of the present invention are, user number is managed automatically, need not memory when the user uses the user, find automatically can with user number register deletion, be the convenient Fingerprint Lock of using easily of user.

Below in conjunction with specific embodiment the present invention is done comparatively detailed description.

Embodiment

Embodiment 1, for Fingerprint Lock user automatic coding: in this enforcements in the Fingerprint Lock each user all have and number, all numberings are weaved into a bitmap array, each represents a Customs Assigned Number, they are layout successively from small to large.Use certain user, position, position for correspondence, delete certain user's data,, empty all users for clear position, the position of correspondence, with the clear position of all data bit, when searching for operable user, need by the user, from front to back, or search for the bitmap array from back to front and find at first position for clear position, and change into user number, and user number is returned, what this returned is to use empty user number, during user number that search can be deleted, need by the user, from front to back, or from after the march forward line search bitmap array of advancing find at first position for set, and change into user number, and user number is returned.

Claims

1. the method for an automatically coding user number of fingerprint lock, each user is identified by user number in the Fingerprint Lock, each user number all has available, has been used two states, it is characterized in that: when system uses user number, note these states, when needs use available subscribers, search for these user number states, find out the available customer location of finding at first, and be encoded into corresponding user number, return available subscribers number; When user number that needs have used, search for these user number states, find out the user number position of finding at first of having used, and automatic coding becomes user number, return and use user number.
