Problems solved by technology
[0002] Usually, electronic locks use air tongues for positioning, and the linkage switch confirms that the door is closed and automatically locked. Because the air tongues need to be hit, the locks generate noise
[0003] There are also electronic locks that use magnetic positioning to lock automatically. Due to insufficient magnetic precision, the lock tongue may hit the lock plate before it reaches the lock, which will cause noise. It needs to be repeated several times before locking; Lock
[0004] Use infrared positioning, with precise positioning, precise control of the lock tongue inserted into the lock hole, so as to achieve silence, but infrared is easily affected by the human body, objects, and the environment, which may generate false door closing information

Embodiment Construction
[0015] The present invention will be further described below in conjunction with accompanying drawing:
[0016] See figure 1 , Piece 3 has two sets of infrared emitting and receiving components, emitting infrared waves, and Piece 2 is a locking piece with bright and black stripes on the door frame, the shape is shown in figure 2 , can detect the reflected infrared light, and as it moves towards the door closing direction, it will show a waveform whose width ratio is roughly consistent with the stripes on the lock (because the door has inertia, the speed cannot be changed suddenly).
[0017] See image 3 , when the door is closed, the level changes of the two infrared transmitting and receiving components are as follows:
[0018] 1 if there is a reflected signal, and 0 if there is no transmitted signal
[0019] position number
[0020] Position 1 is to start closing the door, and position 6 is the locking position. According to the sequence, it can be judged wheth...

The invention belongs to the field of electronic locks and specifically relates to an infrared door position detecting intelligent lock. Aiming at solving the technical problem, the invention providesan electronic lock to prevent error locking caused by error judgment of an infrared door position detecting device. The infrared door position detecting intelligent lock comprises a motor, a spring bolt, a lock plate, a lock cylinder, a door position detecting device, a lock position sensor and a control unit, wherein the door position detecting device is characterized in that an infrared reflection plate is arranged on a door frame, a plurality of brilliant-black alternate stripes are arranged on the infrared reflection plate, and an infrared emitting device and an infrared receiving deviceare correspondingly arranged on a lock body. When infrared ray is applied to location, a latch bolt is avoided; when a door is closed, no impact is generated, and silence is achieved; meanwhile, errorlocking caused by fault door closing information possibly generated by interference is avoided.
Description
technical field [0001] The invention belongs to the field of electronic locks, in particular to an intelligent lock with an infrared door position detection device. Background technique [0002] Usually, electronic locks use air tongues for positioning, and the linkage switch confirms that the door is closed and automatically locked. Because the air tongues need to be hit, the locks generate noise. [0003] There are also electronic locks that use magnetic positioning to lock automatically. Due to insufficient magnetic precision, the lock tongue may hit the lock plate before it reaches the lock, which will cause noise. It needs to be repeated several times before locking; Lock. [0004] Using infrared positioning, it has the advantages of accurate positioning, precise control of the lock tongue inserted into the lock hole, so as to achieve silence, but the infrared is easily affected by the human body, objects, and the environment, which may generate false door closing info...
