Description
Technical field
The present invention relates to a kind of electronic safety lock, particularly a kind of wireless anti-theft alarming world lock.
Background technology
Existing electronic lock is many works hard at aspects such as password setting or opening ways.Its type of alarm generally is an onsite alarming.The fence coverage of onsite alarming is very limited, and the thief that is stolen easily is vindictive damages and lost efficacy.World lock is present security door a kind of mechanical lock commonly used, though it has good pick-proof performance, can not stop the burglar to sabotage.
Summary of the invention
The objective of the invention is in order to solve the deficiency that the above-mentioned background technology exists, provide a kind of and can come the wireless anti-theft alarming world lock of alarm host machine duty in the control room according to the action that world lock opens the door, closes the door, locks a door.
The present invention adopts following technical scheme for achieving the above object: a kind of wireless anti-theft alarming world lock comprises the lock body, locking bar, connecting rod, position sensing switch and the flexible uvula that are loaded on the security door; The receiver each several part of alarm signal emitter and this signal, it is characterized in that: on security door, position sensing switch S2 is housed with lock interlinking lever end corresponding position, the world, flexible uvula is positioned at the side of security door, at flexible uvula place one position sensing switch S1 is housed; The alarm signal radiating circuit is made up of trigger module MK, coding unit IC and high frequency transmission circuit 3; The end of the input of trigger module MK and position sensing switch S1, S2 links, and the input of its output and coding unit IC links, and the output of IC unit links through the base stage of resistance R 5 with the input triode N2 of high frequency transmission circuit 3; Be connected to capacitor C3, C4 on the base stage of N2 simultaneously, resistance R 5, capacitor C 4, C3, triode N2 are formed the high frequency modulated circuit, and the output of this high frequency modulated circuit is to be connected to the high frequency transmission circuit of being made up of capacitor C 5, CW, antenna 4 and inductance L 1 on the colelctor electrode of triode N2.
Capacitor C 5 in the described high frequency transmission circuit 3 links with the colelctor electrode of capacitor C W and antenna 4 backs in parallel and triode N2, is connected to an inductance L 1 on another node of this parallel circuit.
Described position sensing switch S1 is through one by resistance R 1, R2, the pulsed triggering circuit that capacitor C 2 and triode N1 form and linking with the input of trigger module MK.
Described position sensing switch S1 and S2 are respectively equipped with P separately and Q two gears are put the sensing contact, contact P ground connection, and contact Q links through resistance R 3 and power supply.When flexible uvula A indentation, S1 links to each other with contact P point, and when stretching out, S1 links to each other with the Q point; When world lock pinned, S2 linked to each other with contact Q, and when opening, S2 links to each other with contact P.
Position sensing switch S1 of the present invention, S2 also are placed in simultaneously on the security door position that can sensed position changes respectively, and trigger module can change according to the Different Logic of its signal input part level be discerned normal switch or force open the door action.When its input signal end S1, S2 link with the Q end simultaneously, the trigger module action, the output high level pulse is given coding unit, starts high frequency transmission circuit, sends alarm signal, and receiver is promptly finished alert program after receiving alarm signal.
Concrete operating principle of the present invention is: when the user at closing time, in the flexible uvula indentation door, the position sensing switch S1 that meanwhile is positioned at flexible uvula place disconnects, when the user locks a door with key, along with the action of world lock, world lock interlinking lever end can be pushed down position sensing switch S2, and S2 is closed, circuit part is along with sending high-frequency carrier signal, comes that alarm host machine is on the alert in the control room.After this, if there is the people illegally to enter the room from balcony or window, indoor infrared probe sends the signal enabling alarm host machine at once, notifies the user with liaison mode, and the scene does not have sound, also can install the onsite alarming device as required additional; When the user used the key normal door, lock interlinking lever end meeting released position sensitive switch S2 in the world opened S2, removes the state of alert of indoor alarm host machine; If the thief forces open the door and goes into, flexible uvula can eject automatically, and the position sensing switch S1 of its connection and then closes, and reports to the police thereby send the signal enabling alarm host machine.
The present invention has the remote alarms function, fence coverage is big, disguised strong, the alarm signal of emission can penetrate the lock body metal screen layer, compare with the anti-theft product of other type, remote controller of no use, avoided to greatest extent because the wrong report that improper use causes: its external power supply of no use, avoided because failing to report of causing of power failure or artificial destruction electricity consumption facility.The present invention is applicable to door, and multiple occasion such as car door, file cabinet, safety cabinet is used.
