Description

Controller for electronic code theft-proof door

The utility model relates to a kind of lockset, relates in particular to a kind of computer cipher security door controller.

At present, various coded locks are a lot, and what machinery was arranged also has an electronics.Mechanical coded lock exists the shortcoming that its password can't be revised after making.And most electronic password lock usually adopts common digital circuit to combine, so circuit complexity, cost height, and reliability is also poor, does not therefore popularize as yet.

The purpose of this utility model is to provide a kind of simple in structure, dependable performance, lower-cost computer cipher security door controller.

Computer cipher security door controller of the present utility model comprises the controller of keyboard, encoder, the tapered end of importing password and the control tapered end that links to each other with encoder, and described controller comprises a self-locking electrical equipment and four relays: first relay, second relay, the 3rd relay and the 4th relay; Described self-latching relay comprises two contacts; First contact and second contact, first relay links to each other with described encoder with base stage by the colelctor electrode of triode; Second relay, the 3rd relay and the 4th relay are parallel with one another, and second relay is connected with first contact of described self-latching relay; The 3rd relay is serially connected with the button of locking; The 4th relay is connected with second contact of described self-latching relay; The electromagnetic coil of described tapered end is connected with the contact, contact of the 3rd relay; Described self-latching relay links to each other with the contact of first relay and the contact of second relay.

The utility model adopts the integrated package of self-latching relay and Highgrade integration, so structure is simpler, has reduced cost.And control the work of tapered end by a group relay, improved reliability.

Fig. 1 is a computer cipher anti-theft controller structured flowchart of the present utility model;

Fig. 2 is the concrete circuit diagram of the block diagram of Fig. 1.

Describe an embodiment of the present utility model in detail below in conjunction with above-mentioned accompanying drawing.

Referring to Fig. 1, Fig. 1 is the block diagram of computer cipher security door controller of the present utility model.As shown in Figure 1, this computer cipher security door controller comprises keyboard 2, controller 3 and the tapered end 4 that encoder 1 links to each other with encoder 1; Keyboard 2 is used to input password, and encoder 1 is used for the password of stored user setting, and whether the password of differentiation user input is consistent with the password of preserving, and to controller 3 output signals, is controlled the action of the tapered end 4 that is connected with controller 3 by controller control 3.For prevent that other people from inputing password and opening door lock repeatedly exploratoryly, computer cipher door lock of the present utility model also includes the alarm 5 that links to each other with controller 3.When other people or three inputs of user password mistake, then alarm 5 is worked under controller 3 controls, sends alarm signal, as chimes of doom or light.

Referring to Fig. 2, Fig. 2 is the physical circuit figure of the block diagram of Fig. 1.As shown in Figure 2, it is the integrated circuit (IC2) of TWH9103 that encoder 1 adopts model, and its input is connected with keyboard JK, i.e. keyboard among Fig. 12.Keyboard JK comprises one a group of button (0-9 and *, #) and a coding button K1.Controller 3 comprises a group relay JO, JP, JQ, JR, JS and self-latching relay JZ4.Each relay is to connect like this: relay J O is serially connected with triode BG1, resistance R 4, resistance R 7 and light emitting diode LZD1; The colelctor electrode of relay J P and triode BG2 and base stage and light emitting diode LZD2 are connected in series; Relay J Q links on the encoder 1 by contact JZ4-1 and resistance R 6, the R5 of self-latching relay JZ4; Relay J R connects with locking press button KZ and also is connected on the encoder 1 by resistance R 6 and R5; Another contact JZ4-2 and resistance R 6 and the R5 of relay J S by self-latching relay JZ4 is connected on the encoder 1.As can be seen from Figure 2, the branch road at relay J Q, JR, JS place is parallel with one another.Self-latching relay JZ4 connects with contact JO-1, the JQ-1 of relay J O and JQ, links to each other with power supply then.The electromagnetic coil MFZ of tapered end connects with contact JR-1 and the JS-1 of relay J R and JS, receives on the power supply then.Above-mentioned each relay J O, JP, JQ, JR and JS all adopt the HG4123 relay.As shown in Figure 2, on the output of encoder ICZ, also be connected to a loudspeaker Y1.

As shown in Figure 2, comprise voice ic chip 3 and operational amplifier IC4 as the alarm 4 in 1.Voice ic chip 3 adopts LQ46 in the present embodiment, and operational amplifier IC4 adopts LM386.The operating principle of relevant alarm 4 is that those skilled in the art can understand and realize, has just no longer repeated at this.This alarm links to each other with encoder IC2 by relay J P.

Describe the operating principle of computer cipher security door controller of the present utility model below in detail.At first answer setting code, when the user answers encoding by bit button (K1), key in needed string number string by keyboard JK, the multiplexing number of numeral is not limit.Press the * key then, decontrol button K1, then cataloged procedure finishes.Just now Shu Ru string number promptly became password.The user revises password as planning, and then repeats above-mentioned steps and gets final product.

When locking, the user should click the button K2 that locks.At this moment relay J R gets electronic work, makes its contact JR-1 closure, by the constant close contact JS-1 of relay J S, and the electromagnetic coil MFZ of tapered end energising, dead bolt stretches out and pin (locking) under the effect of self-latching relay JZ4.Two contact JZ4-1, the JZ4-2 closure of while self-latching relay JZ4, after the JZ4-1 closure of contact, relay J Q gets electronic work, makes contact JQ-1 closure; After the JZ-2 closure of contact, relay J S gets electronic work, and constant close contact JS-1 is disconnected, and cuts off the power supply of the electromagnetic coil MFZ of tapered end, thereby finishes the process of locking.

When unblanking, the user clicks the # key at last by keyboard JK input password.If password is correct, triode BG obtain 2 second unlocking signal, make relay J O get electronic work, contact JO-1 closure, this moment, the contact JQ-1 of relay J Q was in closure state, so self-latching relay JZ4 and power connection, the dead bolt by the back locking has been decontroled in self-latching relay JZ4 adhesive.Simultaneously because of continue contact JZ4-1 and the JZ4-2 of device JZ4 of self-locking disconnects, therefore, relay J Q dead electricity disconnects its contact JQ-1; Relay J S dead electricity makes its constant close contact JS-1 be in normally off, has so just finished the process of unblanking.If password mistake then do not carry out said process, the people is exploratory to unblank if having, continuous three mistakes, and then encoder ICZ output makes triode BG2 conducting, relay J P get electric its contact JP-1 closure that makes, and makes alarm 5 work, sends alarm signal.

In sum, the utility model has adopted the encoder integrated package of Highgrade integration, has simplified circuit greatly, has reduced cost; Control with a group relay simultaneously, improved functional reliability.Password of the present utility model on the other hand is that the user can freely set, so confidentiality is higher.
