Electronic lock

摘要

An electronic lockset controller (28) for a door-mounted lockset apparatus (10) comprising a core processor (340) controlling the operation of electronic devices within the lockset controller and including a wakeup signal input, a key card signal input, and a motor signal output, the processor being inactive when the lockset controller is in a sleep mode and active when it is in the active mode; a wakeup control module (312) for switching the lockset controller from the sleep mode to the active mode; a key card control module (314) capable of acting as an interface between a key card reader (26) and the lockset controller (28) such that electronic data may be transferred between the two devices; a motor driver module (326) capable of driving an electrical motor that moves a locking mechanism component of the lockset apparatus between locked and unlocked states; and a motor current sensing module (324) capable of determining the position of the locking mechanism component based on the amount of electrical current sent to the electrical motor.
