This alarming lock is installed on bicycle, and when the external world had the people to touch bicycle, mercoid switch K will connect, and but can produce high level input signal V, and this signal is through NAND gate A
1Output low level V.Because monostable circuit S
130 seconds high level of output time-delay, monostable circuit S
219 seconds low level of output time-delay and 19 seconds high level of time-delay, in 20 seconds, control circuit
Be high level, triode T
3Saturation conduction, NAND gate A
4Input is equivalent to ground connection, is low level, through NAND gate A
4Back output then is high level, can not trigger monostable S
4So, in 20 seconds, touch car arbitrarily and do not report to the police, prevented the false alarm that various factors causes.
The 20th second to 30 seconds between because control circuit
Be low level, triode T
3End, the output signal of XOR gate comparator B can be passed to the back level, and after 30 seconds, QQ
2Be high level, T
3Saturation conduction can not trigger monostable S
4So, the 20th second to 30 seconds between, touch car when there is the people in the external world, two inputs, 5,6 signal levels of XOR gate comparator B height is inconsistent, output high level, NAND gate A
4Output low level triggers monostable S
4, monostable S
4Export 20 seconds high level of time-delay, make the T of electronic switch
1Saturation conduction 20 seconds, thus report to the police 20 seconds.
When the car owner opens lock with key, piston 9 resets, and driving lever 16 pressured switches 4 disconnect switch 4 and promptly cut off the electricity supply, and warning circuit is not worked.
