Abstract

A door locking/opening system includes multiple doors, each configured with a door ID number, a handle, a lock and an I/O controller, the I/O controller controls the corresponding door; multiple door controllers, each door controller connects the I/O controller of the respective door and controls the corresponding door; multiple sensors, each sensor connects the respective door controller and communicates with the corresponding door; a door controller unit, connected with the respective door controller via a decentralized network and controlling the multiple door controllers; the multiple door controllers are digitally connected and communicating with each other via the decentralized network; each door controller contains its local logbook of own activities and a configuration file of the complete door locking and/or opening system, and each door controller configurated to update and synchronize the configuration file with each other in a rotating cycle based on the door ID numbers in an ascending order, beginning with the lowest door ID number.
