Novel Design of Electric Locks Based on iButton

Lin Li-chun

Journal of Guangdong University of Technology. 2009, 26 (2): 1-.

Abstract

HTML ( )

PDF(146KB)

In traditional electric locks power is often supplied from the interior of the locks by battery or alternating currents.The traditional electric lock will just be a normal lock if the supply is powered off by battery or alternating current.It proposes the design of a novel electric lock in which iButton is employed and the power is supplied from the outside.The novel electric lock not only can be burglary-proof,but the power supply problem can be solved.
