METHOD AND APPARATUS FOR A MERGED POWER-COMMUNICATION CABLE IN DOOR SECURITY ENVIRONMENT

摘要

A method controlling access to a door using a merged power-communication cable. An access controlled door lock in door is operated using merged power-communication cable. Access control identification mechanism in door may operate using merged power-communication cable. The access controlled door lock may include a piezoelectric controlled door lock or a standalone door lock or a solenoid controlled door lock. A processing module may operate in door to control access with power interface receiving at least part of the electrical power from the merged power-communication cable. The invention includes a strike plate containing a magnetic sensor aligns by a latch hole to a latch included an access control door lock. The invention also includes using a door conduit to provide the merged power-communication cable to at least the processing module in the door.

主权项

1. An access control module for controlling access through a door, comprising: a power interface coupled to a merged power-communication cable, and controllably coupled to a processing computer in a processing module; said power interface providing a first electrical power to an access controlled door lock; said power interface providing a second electrical power to a communication interface; wherein said processing module, further comprises: said processing computer accessibly coupled with a processing memory containing at least one program step of a processing program system directing said processing computer; said processing computer first communicatively coupling with said communications interface coupled with a merged power-communication cable; said processing computer coupling with a peripheral interface coupled with said merged power-communication cable, with a door position sensor, with a request-to-exit switch, and with said access controlled door lock; wherein all communications between said access control module and a security network pass through said merged power-communication cable, all electrical power to said access control module passes through said merged power-communications cable, and said processing program system comprises the program step of: managing said power interface to distribute said electrical power; and controlling said access controlled door lock based upon interactions with said door position sensor, with said request-to-exit switch, and with said merged power-communication cable.
