Description

Networking IC-card door lock

The utility model relates to the door lock assembly in the building automatic control field, particularly relates to a kind of IC-card door lock.

One, background technology situation:

The IC-card door lock is the new door lock that a kind of and conventional door lock have fundamental difference, it adopts advanced IC-card as unblanking key, integrated use accurate manufacturing technology, computer technology, microelectric technique and modern information technologies, be high-tech product truly, its intelligent characteristics are that general mechanical lock, magnetic card lock is impayable.In developed countries such as America and Europes, the IC-card door lock is widely adopted, in China, progressively substituting traditional product, but IC-card door lock ubiquity there is not network savvy in the market, the reporting the loss and write down extraction and can only run back and forth of card number by waiter, it is low to exist efficient, the shortcoming of poor reliability.

Two, the utility model purpose:

The purpose of this utility model just provides with intelligentized high-tech product IC-card door lock and substitutes traditional mechanical lock, magnetic card lock, and give full play to the network savvy of IC-card door lock, make management science, the modernization more of hotel, hotel, high-grade office building, operating efficiency is higher, and benefit is better.

Three, technical solutions of the utility model:

The utility model external structure is made of preceding lock body (1), rear locking (2) and lock core (3) three parts, and the circuit board in the lock body constitutes wherein preceding lock body (1) by draw-in groove (4), indicator lamp (5), preceding shank of the key (22) with before being contained in; Rear locking (2) is by locking knob (6) and back shank of the key (21) formation; Lock core (3) is dialled dead bolt (8), dead bolt (9) and is locked tongue (10) formation by anti-, and three parts are connected with bolt by mechanical part.Be fixed on during use on the wooden door-plate (7).

The utility model internal circuit is made of single-chip microcomputer (11), data-storing module (12), card reading module (13), clock module (14), low voltage detecting module (15), drive circuit (16), motor (17), signaling module (18), power module (19), networking module ten parts such as (20), the electronic devices and components that constitute these modules or circuit are cured on the circuit board that is printed on printed circuit, and are contained in the preceding lock body.Single-chip microcomputer (11) links to each other with above-mentioned module or circuit by printed circuit, and by the above-mentioned module of program directs or the running of circuit and the running of motor.After IC-card inserted, IC4 the 9th pin (SW1) step-down on the circuit board uprised single-chip microcomputer IC1 (89C51) the 13rd pin (INT1) by 74HC02.After single-chip microcomputer ICI (89C51) detects the card insertion, power on to card by its 6 pin (P1.5), Card Reader then, company code, Card Type, effective time, room number and password are arranged on the card, judge behind the Card Reader, as correctly then carrying out action and giving a green light such as unblank,, then be failure to actuate and send out a warning as incorrect.

The realization of the utility model network savvy is that single-chip microcomputer IC1 (89C51) is connected with special chip IC 6 (MAX487) by its serial ports, and carries out 485 communications by chip IC 6 (MAX487) level conversion.The 10th pin (RXD) of single-chip microcomputer IC1 (89C51) links to each other with the 1st pin (RO) of IC6 (MAX487), be used for receiving data, the 11st pin (TXD) of single-chip microcomputer IC1 (89C51) links to each other with the 4th pin (DI) of IC6 (MAX487) and is used for sending data, and the 2nd, 3 pin (RE, DE) of the 8th pin (P1.7) of single-chip microcomputer IC1 (89C51) and IC6 (MAX487) link to each other to control and send and accept data.IC6 (MAX487) the 6th, 7 pin (A, B) are connected to whole network.So just realized the networking of IC-card door lock.

Four, effect.

The more traditional mechanical lock of IC-card door lock, magnetic card lock have intelligentized characteristics, are the high-tech product that electronics combines with machinery, and be more scientific and reasonable to the management of door lock, with the conventional door lock ratio, has following positive effect.

1, standardization, standardization production, superior performance, outward appearance are elegant and graceful: the IC-card door lock and the card key that uses meet the ISO-7816 of International Standards Organization standard, have good versatility.All members are all selected high-grade metal material for use, by pressing mold or mold casting forming, have special antitheft (anti-saw, pick-proof, anti-dialling) function, and its manufacture craft is meticulous, exotic shape, and typical American-European style is adopted in configuration design, and is graceful luxurious.

2, safe: the IC-card key adopts to encrypt and makes, and can not decipher and duplicate, and replaceable password, none screw of door lock exposes, and is safe and reliable.Improved the safety precaution performance of door lock greatly.

3, intelligent good: a microcomputer is housed in the door lock, but the level-right of the legitimacy of identification card, card and unblank to write down card number automatically at every turn, it is for future reference to store up-to-date more than 200 information of unblanking.

4, multiple functional: kind surplus the IC-card key can be divided into ten by its function, rank, satisfy the door lock managerial demand fully, can inquire about, report the loss arrangement to institute's hair fastener, scientific management door lock key.

5, long service life: IC-card can use more than 100,000 times, and information can be preserved more than 10 years.

6, owing to the utlity model has network savvy, not only can be by all IC-card door locks of total platform control hotel, but also can with the supporting use of Hospitality management system, realize hotel's " all-purpose card " consumption.
