Abstract

The present invention relates to digital electronic technology. The cipher writing device includes one flat box with a 16-key keyboard in the panel, a circuit chip inside it and signal I/O feeding belt with 12-pin socket in the end. The inductive card cipher writing process in the keyboard includes three steps of: changing original cipher into user-set cipher; writing the inductive card in the cipher keyboard writing device to form door opening card to electronic lock; and clearing the inductive card to ensure safety in case of losing inductive card. The cipher writing mode is intuitive and simple.

Description

Contactless card code keypad write device and wiring method thereof

(1) technical field

The invention belongs to the Digital Electronic Technique field, specially refer to a kind of contactless card code keypad write device and wiring method thereof.

(2) background technology

Contactless card is a kind of non-contact IC card, involved in the present invention to be a kind of radio-frequency card, it is to utilize radio-frequency technique, by carrying out data transmission mutually between wireless signal and the automatic identification controller (receiving circuit), realize the application of high safety reliable technique with a kind of specific coding, decoding process, such as the application on electronic lock and corresponding auxiliary facility thereof.Wherein, how crucial technology is the password on the contactless card is written in the storer in the automatic identification circuit easily by a code keypad write device, and disposes from storer.Writing and clearance technique of at present domestic and international similar products, all be to rely on original master card or card is set and removes the general wiring method that blocks to write and remove, its safe reliability is not high, the initialization operation that has is fairly simple, the situation that former card is lost especially takes place, its clear operation extremely bothers, must all collect all cards that open the door of this electronic lock, full scale clearance in advance, and then again every card of remainder is write one time again, do like this user is brought very burden, subscriber household or unit that the card of having a large population is promptly many, that more feels to use is loaded down with trivial details.Thereby just caused and studied a kind of not only safe and reliable but also reduce the code keypad write device of clear card troublesome poeration and its wiring method, allow the user can administer safe whole links and convenient operation of removing card in time voluntarily.

(3) summary of the invention

The technical issues that need to address, be overcome wiring method that original contactless card password relies on master card to security, reliability is not high enough and block many defectives such as troublesome poeration clearly, and redesign a kind of contactless card code keypad write device and work out a kind of wiring method, realize safer, the effective efficiency that writes, removes of code keypad easily, make the user can be with the whole links of grasping electronic lock safety voluntarily and the operation of removing former card.For reaching this purpose, be to adopt following technical scheme to realize, a kind of contactless card code keypad write device, comprise a flat box body, box surface is the panel that a piece of cloth has keyboard, a circuit chip is equipped with in box body inside, it is characterized in that, be provided with 16 keys on the key panel altogether, numerical key 0-9 totally ten arabic numeral wherein, the following row left and right sides is two operating key positions, the right side vertical setting of types is 4 function keys, the box body bottom side is the feeder line braid over braid of signal input and output, and its end is 12 pin gang sockets.

The described operating key position of row's and arranged on left and right sides down that is positioned at, the one, home key *, another is reset key #;

4 function keys of described right side vertical setting of types, they are the F1 write key successively, and F2 blocks key clearly, and F3 is from establishing cryptographic key, F4 spare key;

A kind of contactless card code keypad wiring method comprises that three write content, and they are original password changes, contactless card writes and block removing, it is characterized in that, are undertaken by following program step:

1) user changes to original password from establishing password earlier before use

A) energized, blinking red lamp;

B) put the antenna induction district that induction is stuck in write device, it is normal that red light continues bright;

C) on keyboard, press the * key, continue brightly until amber light, and can hear for normally " toots " one;

D) key in the F3 function key, amber light goes out;

E) key in the original password that writes, green light is once glittering, enters next program; Do not work as green light, illustrate that original to write password wrong, must change again, then should be from the operation again again of C step;

F) key in from the password of setting that writes, the glittering secondary of green light enters next program; Not glittering as green light, illustrate that key entry is wrong from setting code, need from the operation again again of C step;

G) repeat to key in one time again from the password of setting, glittering three times of green light, then to write password correct in explanation, finishes change of secret code, not glittering as green light, illustrate to change wrongly, should operate again from the C step;

2) the keyboard write device that accesses to your password writes contactless card, makes it become the card that opens the door of electronic lock;

A) put the antenna induction district that induction is stuck in write device, it is normal that red light continues bright;

B) on write device box body keyboard the * key being pressed to amber light continues bright;

C) press the F1 function key on keyboard, amber light goes out;

D) key in from the password of setting that writes, bright as green light, enter next step operation;

E) key in the contactless card sequence number, bright as green light, then write and finish, card promptly can be used for opening the door; Otherwise repetitive operation is a) to e) step;

F) repeat e) key in the contactless card of other sequence number, this design of control program regulation can write 4 at most and open badge;

3) lose when the card that opens the door, must remove immediately, so that guarantee safe and reliablely, the contactless card sweep-out method is:

A) with arbitrary existing contactless card among family or the member of unit, can be neocaine also, place the antenna induction district, it is normal that red light continues bright;

B) on keyboard, press the * key, continue bright until amber light;

C) press the F2 key, amber light goes out;

D) key in from the password of setting that writes, green light is glittering;

E) key in the contactless card sequence number lost, green light is glittering, finishes removing, then the contactless card of sequence number with unrenewable in opening the door.

The realization of above-mentioned technical method must have code keypad, can enough guarantee to finish the input of password, this keyboard can integrally be done together with automatic identification controller, also can use as a code keypad write device of specially joining separately, in the time of need writing card, as long as write card, card and password modification clearly with finishing in the connection of 12 needle sockets, its software must have the password identification comparison program to realize.

Good effect of the present invention is, the present invention solved the writing of contactless card well, remove and have security and convenience, password writing mode easy operating directly perceived, simple.And the password write device can buy for each user, also can hire at low rentals, and element manufacturing is with low cost.
