Rectifying and voltage-stabilizing: alternating current 220V for after exchanging 10V, is delivered to 1,3 pin of bridge heap QD by outer contact a1, b1 through transformer 28 step-downs, after bridge heap QD rectification, exports a pulsating dc voltage by 4 pin 2.After C5 filtering, deliver to 1,2 pin of three terminal regulator U7 again, 3 pin output direct current 8V burning voltage.

Automatically the DC voltage one tunnel of 3 pin of charging: U7 output is through the R12 current limliting, D4 is higher than the anode voltage of D2 by outer contact c2 to voltage, and this voltage also is the voltage of standby storage battery 29, so when alternating current, system starts power vd D and has only U7 to provide, and standby storage battery 29 is not powered.When no alternating current, the anode no-voltage of D5, at this moment, standby storage battery 29 starts power vd D power supply through D2 to system.Since D5, the anti-phase buffer action of D4, and standby storage battery 29 voltages can not sent into 3 pin of U7.

Power supply switches: system is started between power vd D and the total system power supply VCC switch reliably.Because no matter the general user has people or unmanned in the family, its security door generally is a locking states, the time of locking states is much larger than the door opening state time, and the quiescent dissipation of this Circuits System startup power vd D is the circuit power consumption of locking states, only be equivalent to total system power supply VCC quiescent dissipation and be unlocking condition circuit power consumption 10%, so can solve the long-time powerup issue of system after selecting for use the standby storage battery 29 of small size low capacity to adopt to prevent to have a power failure in the family.Its principle is: when unblanking with remote controller, press remote controller buttons S2 after, after the master chip U1 received signal, 6 pin are exported a high level, lead up to outer contact c4, b8 to give and open and close lock logic control circuit (8), lead up to outer contact c4, b5 through D1, by R11 current limliting conducting Q2 immediately K13 pin be L immediately, 2, the K1 adhesive makes 6 pin connect, the VDD power supply of e5 is supplied with VCC immediately, total system gets electric in the moment of unblanking, simultaneously, VCC keeps the Q2 conducting by D1, R11, makes K1 self-locking adhesive.When door close put in place after, optoelectronic switch GK2 exports a high level, the one tunnel sends into 5 pin of U5, one tunnel base stage of sending into Q2 by outer contact c8, d5 through 1 pin and 2 pin, the R10 of C10, U6.Because the characteristic of electric capacity response sudden change level, when the output of optoelectronic switch GK2 jumps to high level in a flash by low, it is H that its peak levels makes 1 pin of U6 by C10, and 2 pin are L simultaneously, and the base stage of Q2 be L also, and Q2 ends, K1 disconnection, VCC dead electricity.System transfers the VDD power supply state automatically to.

Detailed description about bi-directional logic driving in the electric control system:

Bi-directional drive: when 2 pin of U4 are L, 6 pin are also exported L, after 11 pin, 10 pin of U6 were anti-phase, by outer contact f8, a3, R19 made the Q3 conducting, K2 adhesive simultaneously, VCC powers to a utmost point of micromachine 16 by 6,2 pin of K2, outer contact e3, and simultaneously, another utmost point is by outer contact d3,2,5 pin through K3 form the loop to negative pole, and this moment, micromachine 16 turned clockwise.When 12 pin of U5 are L, its 8 pin is also exported L, after 5 pin, 6 pin of U6 are anti-phase, by outer contact e8, b3, R20 makes the Q4 conducting, simultaneously the K3 adhesive, VCC powers to another utmost point of micromachine 16 by 6,2 pin of K3, outer contact d3, and by a utmost point by outer contact e3, form the loop through 2,5 pin of K2 to negative pole, micromachine 16 is rotated counterclockwise at this moment.

About opening and closing the detailed description of lock logic control in the electric control system:

The logic control of unblanking: after U1 receives remote signal, 6 pin are exported a high level is delivered to U6 after the R8 current limliting by outer contact c4, b8 13 pin, through anti-phase 2 pin of sending into U4 of U6, after the buffering of the two poles of the earth, 6 pin of U4 are also exported L, be H again after U6 is anti-phase, conducting Q3 after the R19 current limliting, K2 adhesive, micromachine 16 positive turn-off locks, after the dead bolt retraction puts in place, mechanical mechanism cuts off GK1, makes it be output as H, and this H level is delivered to 9 pin of U6, send a L level it to be resetted through anti-phase its 8 pin, make micromachine 16 stalls by 4 pin of R16, D7, outer contact a8, d4 to U1.

Latching logic control: when the door turn-off transient, magnetosensitive switch 22 receives the magnetic signal of permanent magnet 27 of outer lock box 23 and closure, by outer contact c7, d7 makes 2 of U3,6 pin and C6, the non-earth terminal of R13 is communicated with, because of it is L, so 3 pin of U3 output H, its peak levels is passed through C8, not only to the C7 charging, simultaneously by outer contact b7, d8 delivers to 3 pin of U6 after U6 is anti-phase, and 12 pin that make U5 are L, after the buffering of the two poles of the earth, 8 pin of U5 also are L, again through 5 pin of U6, the anti-phase back output of 6 pin one high level is by outer contact e8, b3 and R20 conducting Q4 make the K3 adhesive, make micromachine 16 counter-rotatings, after main dead bolt 2 goes out to be locked into the position, mechanical mechanism cuts off optoelectronic switch GK2, makes it be output as height, and its peak levels is delivered to 1 pin of U6 through C10, after its 2 pin is anti-phase, low level is passed through R10 again, outer contact c8, d5 delivers to the base stage of Q2, and Q2 is ended, and K1 resets, total system power supply VCC dead electricity makes micromachine 16 stalls.

In addition, after pressing remote controller buttons S2, though main dead bolt 2 retraction puts in place, when the user did not open the door, circuit can be delayed time and be stretched out locking again from command of execution master dead bolt 2 in 6 seconds.Principle is as follows: unblank moment, whole circuit VCC immediately electric, a peak levels is charged to C6 by C9 rapidly, be H, but because does not open at the back door of unblanking, magnetosensitive switch 22 still is a closure state, electric charge on C6 is through R13, because R13 equals RC discharge time, so after R13 released gradually, 2, the 6 pin level of U3 were L, its 3 pin output high level, thereafter process is the same, can drive micromachine 16 counter-rotatings, thereby reach automatic delayed locking function.

The control of open and close lock sound: when unblanking, the H level of 10 pin of U6 output is conducting Q3 not only, and makes HXD type buzzer LS sounding by D10.After unblanking to put in place, 10 pin of U6 are L, and sound stops; During locking, the H level of 6 pin of U6 output is conducting Q4 not only, and makes buzzer LS sounding by D11, and after unblanking to put in place, 6 pin of U6 are L, and sound stops.

Detailed description about coding and decoding numerical control processing in the electric control system:

Code verification: after clicking button S1, press remote controller key S2 this moment again, then remote signal receiving circuit (6) passes through outer contact h6, a4, R6 with the signal that receives, through anti-phase 18 pin of sending into U1 of Q1, then the two LEDs of its 2 pin output H order extinguish after glittering 0.5 second.After the coding of the button S2 of remote controller output was successfully confirmed, two LEDs extinguished after bright 3 seconds, and whole affirmation process finishes.If two LEDs are glittering greater than 5 times/second fast, then failure is confirmed in expression, must carry out code verification once more.By next time, U1 does not receive signal in 30 seconds, will abandon this code verification automatically as the S1 key.Surpass 8 seconds if press the S1 key for a long time, U1 will remove automatically and deposit content in the memory chip U2, and the coding of all remote controllers that the user set was lost efficacy, and at this moment, should carry out new code verification.

Remote controller quantity and overflowing: U1 and U2 coding and decoding system can support 15 remote controllers to carry out code verification at most.When surpassing, U1 will remove the coding of the remote controller of confirming the earliest automatically.
