Button AN1～10 are contained on the iron gate panel, as the enter key of 10 numerals.A, b, c, d, e, f can arbitrarily receive " 1～0 " end among the figure, both can a termination one, again can several ends and connect after connect one.Now lift the example of a coded number 330506, answer a → " 3 ", b → " 3 ", c → " 0 ", d → " 5 ", e → " 0 ", f → " 6 ".

Diode D1～D10 isolates two groups of different signals so that control two groups of signals with one group of switch with D11～D16, and promptly unblank control and error code detect.Introduce respectively below:

The Q0 of circuit original state IC1 is a high potential, after the button that a end is connect is pressed, current potential will be sent into the CP end of IC1, at this moment Q0 becomes electronegative potential, Q1 becomes high potential, as mentioned above, order is pressed Q1, Q2, Q3, Q4, behind the button that Q5 connect, be exactly 330506 in this example, Q6 will obtain high potential, and this high potential is exactly the instruction that triggers 12 actions of controllable silicon silicon SCR2 control electromagnet, so controllable silicon SCR 2 triggers, be stored in electric energy on the C9 and send into the coil of electromagnet 12, lock is unlocked, subsequently T5 provide immediately one accurately reset pulse reset to IC1 and IC2.T7 is upgraded to high pressure by self-oscillation by TR1 with 6 volts of low pressure of battery, charges about 3 seconds of charging interval to C9 through D24.T6 is failure of oscillation voltage stabilizing control.

Another road push button signalling is sent into T1 and is carried out error code and detect, as long as press wrong key, CP can not trigger because of no high level, and T1 conducting simultaneously (the pseudo-key that this machine is unfixing) is exported a pulse and resetted through IC1 through D18, and delivers to the error code counting circuit.And after pressing correct key, a positive pulse at first can appear in circuit, this positive pulse can not make the T1 conducting, but C3 is charged, when positive pulse is gone over, and the hand of button can't unclamp immediately, and at this moment T1 will conducting, thus output error code signal, at this moment unallowed, designed controllable silicon SCR 1 for this reason, when this happens, SCR1 conducting immediately (electricity that fills on the C3 is as triggering signal), with the voltage of the T1 conducting ground of releasing, unclamp button T1 and end, SCR1 also recovers to turn-off, and this has just guaranteed the correctness of error code signal; When IC2 connect send into 3 pulses after, Q3 becomes high level, reports to the police through warning IC4 power supply, charge to C4 through R5 in another road, C4 goes up voltage and reaches reset level after half a minute approximately, IC2 resets, the last nothing of Q3 is electric, warning stops.During reporting to the police, high level arrives the IC1 reset terminal through D19, so at this moment the electronic password lock refusal is accepted any input code.Above-mentioned time-delay reset is actually insecure, and the result who resets often makes IC2 can not get back to the original state that Q0 is a high potential, for this reason, the reset circuit that design T2 forms, when reporting to the police beginning, high level charges to C5 through R8 and was full of in about 1 second, because of T2 base emitter-base bandgap grading all connects same current potential, thus not conducting of pipe, when time-delay finishes, Q3 becomes low level, T2 base potential step-down, emitter-base bandgap grading is because of there being C5 voltage higher, so pipe conducting immediately, C5 is gone up high potential deliver on the reset terminal, finished reliable reset.

IC3 forms the ding-dong doorbell circuit.

IC5 is a liquid crystal display electron clock, by R19, the power supply of D29 lowering and stabilizing blood pressure, when AN13～17 are the accent standard, reach the control button that whether makes a noise when making a noise, when the user mix up in advance noisy the time one hour the electric current of back " a 14 " end faint time-delay of output that arrives, after amplifying, amplification driving circuit T10, T9 conversion supplies with controllable silicon SCR 3 trigger currents, if at this moment on emergency sooket 17, plug charged emergency power supply,, SCR3 unblanks thereby will giving electromagnet 12 with the electric energy that C17 upward stores by plug 17.Also can meet an urgent need when the contingency circuit is malfunctioning like this and open the door.

The TR2 transformer is contained in the plug special, and rectifying and voltage-stabilizing is located in the machine, so not only can save the space but also prevent power transformer heating, the more important thing is that having prevented that the user from connecing supply voltage polarity burns circuit on the contrary.

The utility model has following advantage compared to existing technology:

1. power consumption is extremely low, if calculate for 12 times by unblanking every day, average power consumption is surveyed only 20 microamperes of static power consumptions less than 0.15 milliampere, uses separately four joint 5# common batteries, available 3～5 Month, adopt the DC-AC two-use scheme, not to be afraid of long-term continuing and to have a power failure, four joint 5# common batteries can be with 1～2 year.

2. adopt the lock body structure of particular design, complete function is complete, and the driving power of electromagnet reaches 400 watts, and only 3～5 milliseconds of power-on times, so reliable in action and extremely power saving.

3. circuit is provided with unique error code and detects and counting circuit, there is not fixedly pseudo-code, making it the preventing decryption function improves greatly, when accumulating error code three times, circuit is reported to the police immediately, has improved antitheft effect, in have and report to the police and doorbell switch, can turn off when not reporting to the police, make things convenient for the unlikely frequent warning of user like this, can't unblank by exploration again.

4. be provided with the emergent unlocking function, can exempt user's trouble and worry.When circuit just in case break down, the time that can set in advance according to the user used emergency set that lock is opened in one hour.

5. all adopt new electronic component, volume is little, low in energy consumption, performance is good, and fault rate is extremely low, the firm especially pick-proof of lock construction, install simple, easy to use, practicality can reach commercialized degree, is fit to antitheft uses such as information section, archive, reference room, research office, office, hotel, bank, warehouse, family.
