Open when electronic lock, be located at the electronic lock battery main switch K on the mechanical lock 4, open, connect the electronic lock power supply, the illuminating lamp 16 on the keyboard is bright, as the first number Q that presses password ₁The time, C ₁Through R ₄To SCR ₂G utmost point discharge, make SCR ₂The AK conducting, the conducting electric current is through J _1-1Over the ground; As the second order digit Q that presses password ₂The time, C ₁Through R ₆, D ₁To SCR ₃G utmost point discharge make SCR ₃The AK conducting, the conducting electric current is through SCR ₂, J _1-1Over the ground; As the 3rd figure place Q that presses password ₃The time, C ₁Through R ₉, D ₂To SCR ₄G utmost point discharge, make SCR ₄The AK conducting, the conducting electric current is through SCR ₃, SCR ₂, J _1-1Over the ground, SCR at this moment ₄, SCR ₃, SCR ₂A suitable resistance makes J ₂The coil two ends add a component voltage, J ₂Work, the J of often making war _2-2The negative supply of lower circuit is promptly connected in adhesive.As the 4th Q that presses password ₄The time, C ₁Through R ₁₁, D ₃To SCR ₅G utmost point discharge, make SCR ₅The AK conducting, the conducting electric current is through J _2-2Over the ground; As the 5th Q that presses password ₅The time, C ₁Through R ₁₄, D ₄To SCR ₆G utmost point discharge make SCR ₆The AK conducting, the conducting electric current is through SCR ₅, J _2-2Over the ground; As the 6th Q that presses password ₆The time, C ₁Through R ₁₇, D ₅To SCR ₇Utmost point discharge makes SCR ₇The AK conducting, the conducting electric current is through SCR ₆, SCR ₅, J _2-2Over the ground, SCR at this moment ₇, SCR ₆, SCR ₅A suitable resistance makes J ₃The coil two ends add a component voltage, J ₃Work, the J of often making war _3-2The negative supply of electromagnet 6 is promptly connected in adhesive, makes electromagnet 6 work, adhesive block 5, and door promptly may be opened.As the 7th Q that presses password ₇The time, C ₁Through R ₁₉, D ₇To SCR ₈G utmost point discharge, make SCR ₈The AK conducting, the conducting electric current is through D ₆, J _3-2Over the ground, J ₄Work, normally closed some J _4-1Disconnect, promptly disconnect SCR ₁Negative supply, make electronic lock circuit be in complete unlocking condition.When bolt 1 is pushed open, be located at the two-way switch K behind the bolt _1-1Disconnect, promptly disconnect the power supply of electronic lock, K _1-2Connect, promptly connect in the safety cabinet or the illuminating lamp 9 in the room.

From circuit as can be seen, when pressing Q ₈-Q ₁₂Any one button, or do not press Q ₁To Q ₇Order press, all can make SCR ₁Conducting.As: when the first number of password is not pressed and during earlier by the second order digit of password, SCR at this moment ₂Not conducting, i.e. SCR ₃The negative supply access failure, SCR ₃There is not turn-on condition, at this moment C ₁Discharge current must pass through R ₇To SCR ₁G utmost point discharge, make SCR ₁Conducting.J ₁Work, J ₁Close point J often works _1-1Disconnect the negative supply that promptly disconnects electronic lock, circuit can not be worked, thereby play the effect of locking.Normal battle J _1-2The negative supply of alarm 8 is promptly connected in adhesive, make alarm 8 send chimes of doom, also connect simultaneously the negative supply of telecontrol transmitter 12, make emitter 12 work send the signal of telecommunication, remote-control receiver 13 and phone from circuit are contained in the telephone the inside, when receiver is received remote signal, promptly connect phone circuit from, make this circuit working, get through the number of previously selected phone, mobile phone or beeper, if cooperate the recording that records in advance, can make a phone call automatically to report to the police.But phone is also wired connection of circuit and electronic lock password switching circuit from, removes the remote control transceiver from.

From circuit, as can be seen, work as Q ₁-Q ₇Program not by intact or hear the adhesive sound of electromagnet 6 and when being eager to shake door open knob, must decontroling and close K ₂(can be located at bolt after any one position) causes SCR ₁Conducting J ₁Work.Work as K ₀During connection, electric current passes through R ₂To C ₂C is worked as in charging ₂Must pass through R when being charged to certain voltage ₃To SCR ₁G utmost point discharge, SCR ₁Conducting J ₁Work, thus play the effect unblanked in limited time, and the time is by R in limited time ₂, C ₂, R ₃Decision.

Adorning 12 sockets of a row, the Q from circuit behind the door ₁-Q ₇Lead-in wire from left to right be connected on respectively in the socket, these seven promptly is the password position so, Q ₈-Q ₁₂Be connected on Q ₇After the position on, Q so ₇Later position all is the error code position.12 buttons are arranged on the keyboard, 12 corresponding lead-in wires, line end is connected to Miniature plug and dashes to be had and the corresponding number of keyboard, during coding, the password that compile is inserted Q _1-7Socket in, remainder code is an error code.

Phone is circuit from

When pushing the wrong password or in limited time time is up or improperly unblank to cause J ₁Work, the J of often making war _1-2Connect, promptly connect the negative supply of telecontrol transmitter, start receiver gauge tap K ₃Adhesive, circuit is started working, J ₅The switch under the telephone handle is connected in adhesive, simultaneously J ₆Also adhesive, electric current passes through R ₂₁R ₂₂Respectively to C ₅, C ₄C is treated in charging ₄Charge saturated after, C ₅Also saturated, C ₄Promptly pass through R ₂₃To SCR ₉G utmost point discharge, SCR ₉Conducting, C ₅Pass through J ₇Coil, SCR ₉Discharge, J ₇Adhesive, the J of often making war _7-2Connect C ₅After having discharged, J ₇Because through R ₂₂Current limliting make J ₇Not enough current work, J ₇Discharge at once, realized the effect that on the phone storage key, clicks, whole process realized picking up the telephone earlier handle or by behind the hands-free switch by the overall process of making a phone call of phone storage key.

The utility model adopts mechanical lock to combine with electronic lock, makes it have automatic blocking, lock automatically, throw light on automatically, report to the police automatically, get through functions such as call or telephone call automatically, can play antitheft effect effectively.
