Abstract
The utility model relates to a remote sensing theft-proof and alarming lock, comprising a remote sensing signal transmitter and a remote sensing signal receiver. The remote sensing signal transmitter is arranged in a mechanical lock and is connected with the mechanical lock into a whole. The remote sensing signal receiver is arranged on the user part. The utility model adopts a vibrating switch as the alarm signal source. The signal becomes a high-frequency signal after oscillated and amplified. The utility model is transmitted by a printed circuit antenna and is received by a microstrip antenna, through the digital coding. The utility model has the advantages that the volume of the remote sensing signal transmitter is small; the remote sensing signal transmitter is stealthily arranged in the mechanical lock body, and is not easily detected and damaged; the alarm method selects the transmission method with no sounding signal and the sounding direct alarming method; the alarm signal passes through the digital coding; the alarm signal is clearly recognized and is not confused.
Description
The utility model relates to a kind of theftproof lock, particularly the remote sensing anti-theft alarm lock.
Existing theftproof lock does not have warning function more, even have the lock of warning function, do not have the characteristic that the remote sensing transmission control is reported to the police, thereby anti-theft feature is not strong yet.
The purpose of this utility model is to design a kind of lock with the extremely alert function of remote sensing transmission control, destroys lock as the people, and attempt can be reported to the police in effective range when stealing thing automatically in the remote sensing transmission control, thereby has strengthened the anti-theft protection function of lock greatly.
Technical solution of the present utility model is a kind of remote sensing anti-theft alarm lock, is made of with the remote sensing signal transmitter and the remote sensing signal receiver that split two places button bolt formula mechanical lock, and the remote sensing signal transmitter places in the mechanical lock.
Description of drawings is as follows:
The remote sensing anti-theft alarm lock structural representation that accompanying drawing 1 radiating circuit connects with locking bolt
Accompanying drawing 2 remote sensing signal receiver schematic diagrames
Accompanying drawing 3 remote sensing signal transmitter circuits connect figure
Accompanying drawing 4 remote sensing signal acceptor circuits connect figure
The utility model further specifies as follows in conjunction with specific embodiments, and the remote sensing anti-theft alarm lock is made of button bolt formula mechanical lock [1] and remote sensing signal transmitter [2] that splits two places and remote sensing signal receiver [3].Remote sensing signal transmitter [2] places in mechanism's lock [1], and locking bolt [4] can connect or not connect with the switch actuating of remote sensing signal transmitter [2].
The locking bolt [4] of the button bolt formula mechanical lock [1] of embodiment 1 remote sensing anti-theft alarm lock connects with the switch actuating of remote sensing signal transmitter [2].
Remote sensing signal transmitter [2] circuit is referring to accompanying drawing 3, by miniature slide switch K1, miniature key switch K2, electronics E and vibroswitch K3 are concatenated into on-off circuit [5], K1, K2, K3 all places in the lock body, K1 and K2 place in the locking bolt hole of mechanical lock, K2 switch key button touches with locking bolt [4] and connects, K1 does not connect, and one of K1 is connected to by ic chip 2, the warning circuit that loudspeaker H is connected into [6], K1 is connected to the input of IC2, the other end of K1 is connected to by ic chip 1, diode D1, the digital coding circuit [7] that resistance R 2 is connected into, K1 connects 10 pin of IC1, digital coding circuit [7] is connected to by printed circuit antenna Y1 and Y2 tunable capacitor C2, inductance L 1, triode T1 and capacitor C 1, C3, C4, the signal transmission circuit that resistance R 1 is connected into [8], 17 pin of IC1 are connected to R1.Y1 is a stripline antenna, and Y2 is a loop aerial.Electric routing battery E power supply is connected between K switch 2, the K3.
Remote sensing signal receiver [3] circuit referring to accompanying drawing 4, adopts prior art, referring to the present patent application people's patented technology (ZL94237341.3).Remote sensing signal acceptor circuit 3 is by microstrip antenna Y2, capacitor C 5～C11, inductance L 2, resistance R 4～R7, with triode T2, diode D3 is connected into signal receiving circuit [8], by triode T3, capacitor C 12～C14, resistance R 8～R11 and ic chip 3 are connected into amplification and rectification circuit [9], by coding integrated package IC4, resistance R 13 is connected into digital coding circuit [10], by triode T4, resistance R 12 is connected into on-off circuit [11], by LED, music integrated block IC 5, news Chinese percussion instrument SP is connected into sound and light signal generator [12], it is by the R4 of signal receiving circuit [6] and the R8 that is connected to amplification and rectification circuit [9] altogether of C6 that its circuit connects, the R4 of signal receiving circuit [6], R5 is total to the R10 that contact is connected to amplification and rectification circuit [9] respectively, 4 pin of IC2,18 pin of digital coding circuit [8] IC4, hand over 1 pin of generator [12] IC5 to meet power supply E2 through K switch 2 jointly with sound again, 14 pin of amplification and rectification circuit [7] IC3 are connected to 14 pin of digital coding circuit [10] IC4, the output of 9 pin of digital coding circuit [10] IC4 is connected to the R12 of on-off circuit [11], and on-off circuit [11] T4 colelctor electrode is connected to that sound and light signal is sent out and the LED of device [10] pipe.
Remote sensing signal transmitter [2] places in the mechanical lock [1], connects to make an integral body, and remote sensing signal transmitter [3] places the owner to locate.K2 is the status switch of lock, is touched by locking bolt and presses K2, connects the remote sensing signal transmitter circuit, makes it in running order, can carry out remote sensing signal and report to the police or audible alarm, disconnects then remote sensing warning system of K2 and sound warning system and does not all work.K1 also is a status switch, and K1 has two gears of A, B, connects the A position, and lock is in the remote sensing signal alarm condition, and the receiver at owner place just can receive alarm signal, connects the B position, and then the chimes of doom Chinese percussion instrument SP in the lock just can directly send alarm sound.A, B gear can be adjusted by the user in use and select for use, and vibroswitch K3 places in the lock body, as long as lock once vibration, K switch 3 is promptly connected, just the remote sensing signal warning system is worked.It is 200 meters that sensor alarming signal of the present utility model transmits coverage.
The utility model has the advantage of that alarm signal is high-frequency signal. With printed circuit Antenna transmission and microstrip antenna receive, and therefore, alarm signal transmitter and receiver are all very Little, transmitter places interior the connection with lock of mechanical lock to make one, is easy to stealth and is difficult for examining Feel to cause destruction, type of alarm can select signal transfer mode and the sound of silent direct Type of alarm, signal can clear identifications through digital coding and unlikelyly obscure error.
