Infrared door position detecting intelligent lock

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 do
