LOCKING-UNLOCKING SENSOR AND LOCKING-UNLOCKING CHECK SYSTEM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a locking-unlocking sensor and a locking-unlocking check system using the same capable of reducing the installation time and work.SOLUTION: A determination section 12 is provided to a handle 31 of a lock device 3 which is arranged to rotate relative to a fitting between a position to lock and a position to unlock a fitting, and detects a direction of a magnetic field. The determination section 12 detects whether the lock device 3 is in a locked state or an unlocked state based on the direction of the magnetic field. A transmission section 13 transmits a detection result made by the determination section 12 to a master unit. The determination section 12 uses the direction of the magnetic field detected in the locked state or the unlocked state as a reference direction, and detects whether the locked state or unlocked state, based on a relative change angle with respect to the reference direction of the detected direction of the magnetic field.
