Abstract
The anti-theft alarm for lock includes key with ROM for storing user's cipher, contact disc, control assembly, alarm assembly and door magnet. In fortifying state, the door may be opened only when the control assembly detects the output signal of the door magnet, the control assembly powers, the ROM in the key via conductor and ball assembly and the user's cipher is read out. In case that the control assembly detects the door magnet signal and no user's cipher, the door is judged to be illegally opened and the alarm assembly sends out alarm.
Description
1, technical field
The present invention relates to a kind of burglar alarm, particularly anti-theft alarm for lock.
2, background technology
Lockset in the known technology generally includes lock body, tapered end and key, the safety of lockset all is vital to the life and the property of resident family, and at present commercially available most of locksets do not have the reliable precautionary measures the lawbreaker during to its illegal technical opening, just reach the strick precaution purpose by the difficulty that increases illegal technical opening.Now commercially available burglar alarm normally at the gate, infrared induction or the magnetic induction locating to be provided with such as window or room triggers warning device, but this type of warning device does not have and takes precautions against lockset by the anti-theft alarm function of illegal technical opening.
3, summary of the invention
The objective of the invention is at deficiency of the prior art, provide a kind of and illegally opened, can in time be sent after particularly lockset is caused door to be opened by illegal technical opening the anti-theft alarm for lock of alarm signal at door.
In order to achieve the above object, the present invention is achieved in that and comprises key 2, contact disc 3, Control Component 7, alarm assemblies 8 and door magnetic 12, its special character is to have buried the readable memory 1 that stores user cipher in key 2 underground, the power supply positive and negative electrode of readable memory 1 all is electrically connected a pellet shot from a slingshot assembly 9 separately with the interface that need be connected with Control Component 7, pellet shot from a slingshot assembly 9 is made up of pellet shot from a slingshot 10 and spring 11, and pellet shot from a slingshot 10 and spring 11 are made by the conductive material with certain structural strength.Be fixed on that contact disc 3 on the general lockset tapered end end face is made by insulation materials and offer keyhole 4 at the center, the camber line position that each pellet shot from a slingshot 10 streaked on contact disc 3 simultaneously when contrast was unblanked is laid the arc strip electric conductor 6 with certain structural strength separately, each electric conductor 6 and door magnetic 12 are electrically connected to Control Component 7 respectively, and Control Component 7 is electrically connected alarm assemblies 8.
The present invention compared with prior art has following good effect:
All buried the readable memory 1 that stores user cipher in the key 2 of each mandate underground, have only Control Component 7 just to judge after reading user cipher when opening the door opens the door to legal at every turn, because of the lawbreaker can't find out user cipher, so go into no matter force open the door or illegal technical opening lockset and go into all controlled assembly 7 and be judged to be forcible entry, thereby control alarm assemblies 8 is reported to the police.Therefore, the present invention has fundamentally solved the defective that prior art can not be guarded against fully to illegal technical opening, has improved the safety and the reliability of lockset.
4, description of drawings
Fig. 1 is the composition schematic diagram of structure of the present invention and circuit.
5, embodiment
Fig. 1 shows one embodiment of the present of invention.Wherein readable memory 1 can be the EEPROM of serial line interface, the EEPROM of 24CXX series for example, also can be other readable memory, just require the interface of it and Control Component 7 can not be too many, because can not lay too much arc strip electric conductor 6 on the corresponding contact disc 3.Control Component 7 can be common single-chip microcomputer, also can be other control circuit.Alarm assemblies 8 can be directly or by the sound or audio alert assembly that telephone wire is reported to the police, also can be the tele-alarm assembly of another warning device of remote control.Door magnetic 12 is the tongue tube or the Hall element of a magnetic induction, when the transformation of opening the door or high electronegative potential all should appear in door magnetic 12 output signals at closing time.Because of readable memory 1, Control Component 7, alarm assemblies 8 and door magnetic 12 are prior art, no longer describe in detail here.In key 2, buried the serial line interface eeprom memory 1 that stores user cipher underground, the power supply positive and negative electrode of serial line interface eeprom memory 1 and the interface that need be connected with Control Component 7: data wire SDA interface, clock line SCL interface all are electrically connected a pellet shot from a slingshot assembly 9 separately, pellet shot from a slingshot assembly 9 is made up of pellet shot from a slingshot 10 and spring 11, and pellet shot from a slingshot 10 and spring 11 are made by the conductive material with certain structural strength.Contact disc 3 centers are offered keyhole 4 and are fixed on the tapered end end face of general lockset with screw 5, contact disc 3 is made by having certain thickness insulation materials, pellet shot from a slingshot 10 is pressed because of the tension force of spring 11 and is touched on contact disc 3 when unblanking with key 2, rotate with key 2 and one deck is laid separately less than contact disc 3 thickness and the arc strip electric conductor 6 of certain structural strength is arranged in the camber line position of streaking simultaneously on contact disc 3 at each pellet shot from a slingshot 10, with guarantee each pellet shot from a slingshot 10 on the key 2 unblank sometime in can both touch each self-corresponding electric conductor 6 simultaneously, each arc strip electric conductor 6 and door magnetic 12 are electrically connected to Control Component 7 respectively on the contact disc 3, and Control Component 7 is electrically connected alarm assemblies 8.
When the needs warning is set up defences, can make Control Component 7 work by switch activated power supply, the interface data that is connected to a magnetic 12 and is connected to each electric conductor 6 on the contact disc 3 is ceaselessly read in Control Component 7 beginnings, open the door each time and Control Component 7 is detected be connected to the high electronegative potential of a magnetic 12 interface data to change, if open the door with legal key 2, Control Component 7 can be given 1 power supply of serial line interface eeprom memory and read the user cipher of storing in the serial line interface eeprom memory 1 by the pellet shot from a slingshot assembly on electric conductor on the contact disc 36 and the key 29, high electronegative potential appears in the interface data that is connected to a magnetic 12 if Control Component 7 does not read user cipher to be changed, just the expression door is illegally opened, and Control Component 7 will be controlled alarm assemblies 8 and implement to report to the police.
