SYSTEMS AND METHODS TO CONTROL LOCKING AND UNLOCKING OF DOORS USING POWERLINE AND RADIO FREQUENCY COMMUNICATIONS
First Claim
1. A battery-powered door lock control system operating remotely from a powerline and configured to interface with a mesh network, the system comprising:
- a door lock controller configured to receive a door lock command, the door lock controller in communication with a door lock associated with an entry to a building to automatically move the door lock between a first locked position and a second unlocked position based at least in part on the door lock command; and
a local receiver comprising a first antenna, a second antenna, and a radio frequency (RF) receiver, the local receiver configured to wirelessly detect with the first antenna a presence an electromagnetic field generated by a presence of a carrier signal that is added to a powerline waveform, the carrier signal comprising a first RF signal having a first frequency, the presence of the carrier signal indicating that a first message encoded with said door lock command using said first frequency is modulated onto the powerline;
the local receiver further configured to receive with the second antenna a second message encoded with said door lock command via a second RF signal when the electromagnetic field is detected, the second RF signal having a second RF frequency different from the first RF frequency, the local receiver further configured to determine whether a device address of the second message is an assigned address and to send the door lock command to the door lock controller when the device address is the assigned address.

Abstract
An electronic door lock system automatically controls locking and unlocking of a door. A door lock controller interfaces with an electronic door lock, sends messages including door lock data to a local receiver, and receives messages including door lock commands from the local receiver. In turn, the local receiver interfaces with a hub device through a mesh network. The hub receives the door lock data, applies a rule set to make lock operation decisions, and sends messages, which may comprise commands to operate the door lock, through the mesh network to the local receiver. The local receiver decodes the messages and passes the commands to the door lock controller to automatically control the electronic door lock.

11. A method to control a door lock, the method comprising:
-
detecting with a first antenna an electromagnetic field generated by a presence of a carrier signal that is added to a powerline waveform, the carrier signal comprising a first radio frequency (RF) signal having a first frequency, the presence of the carrier signal indicating that a first message encoded with a door lock command using the first frequency is modulated onto a powerline; receiving with a second antenna a second message encoded with the door lock command via a second RF signal when the electromagnetic field is detected, the second RF signal having a second RF frequency different from the first RF frequency; determining whether a device address of the second message is an assigned address; sending to a door lock controller the door lock command when the device address of the second message is the assigned address; and automatically moving a door lock associated with an entry to a building between a first locked position and a second unlocked position based at least in part on the door lock command sent to the door lock controller. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
