Operating principle of the present utility model is as follows:

1, the state of deploying troops on garrison duty: referring to Fig. 1, this moment lock body 1 with the spacing of snap close 6 in designed distance (normalized distance from), thereby because dead bolt slide plate 4 moves right K2 trigger head 11 is in the strip hole 41, K2 trigger head 11 (the being perk) state that is not triggered, K2 is in conducting state.Strong magnet 7 on the snap close 6 near tongue tube K1 make the K1 conducting.Referring to Fig. 6, this moment is because the effect of balance resistance R8 can not be charged C4, so V4 base stage Triggerless, the 8 pin vdd terminals of rolling code coding circuit 52 ' and high-frequency inductor L2 one end of radiating circuit are in "on" position, and the inboard strong magnets that embed 7 of snap close 7 make K1 be in closure state owing to produce strong magnetic action among Fig. 1, thereby electronic lock being in deploy troops on garrison duty treats alert state.Deploy troops on garrison duty state as can be seen by above, thereby if do not turn the key in the lock this moment or be not to strengthen and surpass designed distance from the open the door spacing that causes lock body 1 and snap close 6 of indoor handle, at this moment the K1 magneticaction that left strong magnet 7 makes K1 produce one to break away from cold end moment and finish by R8 and charge rapidly to C4, isolate C4 charging voltage increase under the cold end effect at R6, make the conducting of V4 base stage, at this moment V4 plays an on-off action, the V4 colelctor electrode sends a pulse to the V3 base stage fast, because the capacity limit of C4 is so the V3 base stage can only obtain a positive pulse signal greater than 1S, the a certain end of the pin selecting side 1-4 pin of rolling code coding circuit 52 ' at this moment gets has one of 6 pin outputs output after electric greater than the 1S negative pulse, finishing a 1S high-frequency signal by radiating circuit 53 after the R2 current limliting triggers V2 NPN crystal switch pipe base stage transmits, trigger sound circuit by diode D1 simultaneously, finish forcible entry voice warning/warning purpose.

2, the state of withdrawing a garrison: referring to Fig. 2, this moment no matter the human key open the door or from indoor to outward opening door, the dead bolt slide plate is moved backward, again when L.H.flapped door moves, strip hole 41 is crossed and is depressed K2 trigger head 11 and cut off the complete machine power supply in designed distance, because at this moment circuit is in off-position, do not have the triggering signal generation so make snap close strong magnet 7 leave the lock body designed distance, so finish the purpose of withdrawing a garrison safely yet.

3, prevent the wrong report state: as can be seen from Figure 3,

(1) lock body 1 and snap close 6 are artificially to break away from designed distance in accordance with the proper operation method in advance, so at this moment dead bolt slide plate 4 moves right, and make K2 trigger head 11 perks energisings, and snap close strong magnet 7 is not effectively triggering in the distance when triggering K1, produces so still do not have triggering signal.

(2) if owing to when this electronic lock is installed, cause lock body 1 bigger than normal for a certain reason with snap close 6 distances, and at this moment since the people he replys from indoor dead bolt 3 not being turned round when going out, but still opened door and dead bolt 3 is ejected and do not report to the police, this is to feed back to R14 inhibition C5 because the positive pulse signal that the colelctor electrode of V3 sends among Fig. 6 is organized R7 by the drop-down electricity of LED1, release by R11 decay and to detect the storage gain pulse width and whether can provide the booster voltage trigger voltage to reach the colelctor electrode that the V5 colelctor electrode promotes interlock circuit V6 and V7, have correct corresponding pulses width to go to trigger the radiating circuit action at last to the V5 base stage.

4, low-voltage detected state: as can be seen from Figure 6, V8 and LED2 have constituted a low-voltage detection circuit, in case supply voltage is reduced to the design threshold, LED2 will glimmer automatically.
