The specific embodiment

Provide specific embodiment below in conjunction with accompanying drawing, how step explanation the utility model is realized.

As shown in Figure 1, memory burglar alarm lock control system, include key 1, the lock body of forming by lock core 2 and the lock beans group 3 more than three 4, in key 1 inserts lock body 4 that part of on not with lock the side that beans 3 contact and be embedded with

magnet

6,6 corresponding places are provided with magnetic memory switch 5 at the lock body 4 upper ends outsides and magnet, in lock body 4 upper ends and the corresponding section, top of inserting the key 1 in the lock body 4, be provided with the magnet 8 of lock beans effect, be provided with feeler lever 12 on the lock beans in lock beans group 3, be provided with reed switch 11 in lock body 4 outsides and feeler lever 12 corresponding positions, native system also is provided with the controlling alarm part that links to each other with magnetic memory switch 5 and reed switch 11.

Magnetic memory switch 5 includes the magnet 7 that is provided with, a side and the magnet 7 corresponding switch blocks 9 that partly link to each other with controlling alarm that are provided with in motion chamber 10 in motion chamber 10.Wherein, switch block 9 can be tongue tube or is photoelectrical coupler.

As shown in Figure 2, the controlling alarm control circuit A that partly includes the power supply E, the music circuit B that are connected in series successively, on-off circuit C, loudspeaker D and link to each other with music circuit B with power supply E respectively.

As shown in Figure 3, control circuit A includes K switch, controllable silicon G ₂, resistance R, the positive pole that an end of its K switch connects power supply E links to each other, the other end connects controllable silicon G by resistance R ₂Positive pole, also connect music circuit B, controllable silicon G ₂Negative pole also link to each other with music circuit B, music circuit B connects the negative pole of power supply E, controllable silicon G ₂An end of the reed switch 11 that is provided with of trigger end and lock body 4 places link to each other, the tongue tube 9 in the magnetic memory switch 5 of the other end of reed switch 11 and the setting of lock body 4 places links to each other the other end of tongue tube 9 and resistance R, controllable silicon G ₂Positive pole, music circuit B link to each other.

As shown in Figure 4, control circuit A also can be designed to: include K switch, controllable silicon G ₁And G ₂, resistance R, its K switch and controllable silicon G ₁Be connected in parallel, the positive pole that an end in parallel connects power supply E links to each other, and the other end connects controllable silicon G by resistance R ₂Positive pole, also connect music circuit B, controllable silicon G ₂Negative pole also link to each other with music circuit B, music circuit B connects the negative pole of power supply E, controllable silicon G ₁And G ₂An end of the reed switch 11 that all is provided with lock body 4 places of trigger end link to each other, the tongue tube 9 in the magnetic memory switch 5 of the other end of reed switch 11 and the setting of lock body 4 places links to each other the other end of tongue tube 9 and resistance R, controllable silicon G ₂Positive pole, music circuit B link to each other.

Operating principle of the present utility model is: wherein, magnetic memory switch 5 is under the situation of lock core 2 no keys 1, and magnet 7 is positioned at the below in motion chamber 10 under gravity and the graviational interaction to tongue tube 9, make reed switch conduction; Reed switch 10 does not have under the situation of key 1 at lock core, is in the disconnection shape, as long as have object to run in attitude lock core 2, reed switch 10 is with regard to conducting.Magnetic memory switch 5 and reed switch 10 are to be connected in series, only under the situation of their conductings simultaneously, control circuit A just can be activated, and music circuit B starts loudspeaker D by booster circuit C and reports to the police, other any state, control circuit A all do not start loudspeaker D and report to the police.

When lockset cut out, K switch was connected, in the time of need opening lockset, the principle of repelling each other according to the magnetic same sex, key 1 enters lock core 2, and at first the magnet 6 that carries by itself repels the magnet 7 in the magnetic memory switch 5 to motion 10 tops, chamber, away from tongue tube 9, make tongue tube 9 become disconnection by conducting, key 1 moves forward, the length of the magnet 6 of itself, all the time control away from tongue tube 9, make tongue tube 9 be in off-state always; Run into the lock beans that have feeler lever 12 in key 1 advances process, feeler lever 12 touches reed switch 11, causes reed switch 11 conductings; After key 1 put in place, magnet 6 that itself carries and the principle that the magnet 8 on the lock body 4 repels each other because of the same sex made magnet 8 move upward and break away from lock core 2 that key 1 rotatable lock core 2 is opened lockset.In this state, though along with the rotation of lock core 2, magnet 6 has lost the repulsion to magnet 7, make magnet 7 get back to the bottom in motion chamber 10, cause tongue tube 9 conductings, but because after key 1 arrives, reed switch 11 is in off-state, reports to the police so can not start loudspeaker.

When false key inserts, magnet 7 there is not repulsion, still conducting of tongue tube 9 along with entering of false key, because of having the lock beans of feeler lever 12, causes also conducting of reed switch 11, makes the control circuit conducting, reports to the police thereby start music circuit.Meanwhile, when false key enters terminal point, because of false key does not produce repulsion to magnet 8, magnet 8 can not break away from lock core 2, still pins lock core 2, the lockset of finally not opening.
