2The password of depositing among the PROM (electricity is rewritten memory) compares, if two yards unanimities, the micromotor that then drives in the circuit that opens the door rotates, drive a worm screw, Worm gear mechanism, discharge the clamp that blocks handle, move handle this moment, can drive the dead bolt in the lock core, withdraw from lock storehouse and opening the door.
Keyboard on the interior lock body and LCDs are used for fabrication and rewrite password and be provided with, and fabrication or revise before the password at first by keyboard input fabrication order, is sent password and left E in by host CPU
2Code word among the PROM is compared, if both unanimities then shield demonstration and can revise password, radio frequency induction card (key card) should be put into this moment on the emitting head of RF oscillator of outer lock body and prepare to write new sign indicating number, and the new password that after this while also will be imported is rewritten to E
2Among the PROM, if inconsistent then refusal is reacted.
In order to overcome power supply or the mainboard chip breaks down and the door of not opening, also be provided with a cover fallback circuit on the interior lock body and link to each other with outer lock body below emergency opening plug receptacle, contain spare CPU and standby E on the fallback circuit
2PROM makes standby E by one group of electronic relay
2PROM switches between host CPU and spare CPU, finishes the transmission of password between main circuit and stand-by circuit.
Owing on lock body, possessed fabrication and changed code function, bring very big facility to the domestic consumer, increased safety and confidentiality, can give full play to the superior quality of electronic lock.
Further set forth detailed structure of the present invention below in conjunction with the example described in the accompanying drawing.
Accompanying drawing 1 is an example of electronic lock
Accompanying drawing 3 is to pull out keyboard and the display screen that is parked in interior lock body top
Can be divided into five functional blocks on this electronic lock circuit: by accompanying drawing 2 explanations
1.RF the radio frequency induction circuit constitutes the RF oscillator by RF radio frequency induction chip U2270B and peripheral resistance-capacitance circuit thereof, by the radio frequency induction circuit, under host CPU control, data signal is modulated into radiofrequency signal and is transmitted to radiofrequency signal that the same key card antenna of radio frequency induction card (key card) sends through antenna and is demodulated to data signal through the radio frequency induction circuit and gives master cpu.
2. governor circuit is mainly by host CPU, keyboard, demonstration and main E
2Prom memory is formed, its effect be finish to backup battery low pressure detect, outage detection when adopting city's power supply, lock and dead bolt go out the implantation site detection, report to the police drive, the light emitting diode indication drives outdoors, motor-driven is opened the door in control, carry out exchanges data, and the communication of peripheral equipment by RF radio frequency induction circuit and radio frequency induction card.
3. stand-by circuit is when motherboard circuit or power supply break down, a kind of emergent means of opening the door that provide, and it is by spare CPU, standby E
2Prom memory, standby motor-driven commutation circuit and form with the electronic relay group that main circuit interrelates, stand-by circuit links to each other with emergency opening plug receptacle J on the outer lock body, when needing emergent unlocking, use a special tool that contains the hand-held emergency opening device of compromise joint to be plugged among the emergency opening plug receptacle J on the outer lock body, have power supply on this instrument, can power to stand-by circuit, also have keyboard, display screen, CPU, E on the emergency opening device
