Efficient and safe door locking control in power-off and power-on conditions

Abstract

Systems, methods, and apparatus are presented for efficiently controlling the operational state of an electromagnetic lock under energized and de-energized conditions. The lock components include electromagnet components (e.g., bi-stable latching solenoids) that hold the deadbolt in the locked or unlocked position without using power to hold the deadbolt in the desired position, and use power from a The location changes to another location. The sensor component senses when power to the lock component is about to be lost, and if the deadbolt is not in the desired position with respect to the power outage condition, can shift the deadbolt to the desired position, and if the deadbolt is in the desired position with respect to the power outage condition , the lock component can then maintain the lock pin in the desired position despite the lock component being in a de-energized condition.

Description

technical field [0001] The present invention relates generally to the operation of electromagnetic door locks and, in particular, to efficient and safe operational control of electromagnetic door locks under de-energized and energized conditions. Background technique [0002] Certain areas (e.g., rooms, safe production areas, etc.) can be accessed via doors (e.g., sliding doors, sliding doors, etc.), where certain restricted areas can be closed by installing locks on the doors leading to the restricted areas, as desired. area. Typically, electromagnetic locks may be used to lock doors leading to defined areas that may be used, for example, for storage of products, for production line operations, and the like. Some electromagnetic locks use magnetic locks or linear electromagnets that require electrical power in order to maintain the lock in the locked position with respect to the door associated with the lock. Conventional electromagnetic locks typically lose their adhesiv...

AI Technical Summary

Problems solved by technology

That is, when power to the electromagnet is lost, the electromagnet in a conventional electromagnetic lock typically loses its retaining force holding the lock in the locked position

Additionally, under energized conditions, traditional electromagnet and electromagnet based locks can consume considerable power and generate heat
