Electronic reset for solenoid activated control in an electronic lock |
摘要 |
The technique for electronically resetting a magnetically sealed solenoid to an unattracted, unactuated position is described for use with solenoids which have either a residual magnetic or a permanent magnet holding force necessary to retain the armature of the solenoid in its actuated position until such time as the armature is either physically displaced by a mechanical force or an electronic signal is applied to the solenoid. This displacement creates a reverse polarity magnetic field, effectively overcoming the magnetic field acting to hold the armature in its actuated position, permitting a small mechanical force to reset the armature. In order to prevent a lock or similar device from being conditioned for opening and possibly left in that condition for a significant period of time while unattended, jeopardizing the security of the container and its contents, the actuation of the armature in the reset or release phase may occur a relatively short time following its actuation.
