Abstract
A closure system including a curtain configured to seal an opening, a wireless network having a plurality of channels, at least one transmitter coupled to the curtain and configured to communicate over the plurality of channels, and an operator operatively coupled to the curtain and configured to communicate over the plurality of channels, the operator and the at least one transmitter configured to communicate with each other over a selected one of the plurality of channels based upon communication interference detected on one or more channels.
Claims16
A closure system comprising:
- a curtain configured to seal an opening;
- a wireless network having a plurality of channels;
- at least one transmitter coupled to the curtain and configured to communicate over the plurality of channels;
- and
- an operator, the operator operatively coupled to the curtain and communicatively coupled to a receiver, and the receiver configured to communicate over the plurality of channels, the receiver and the at least one transmitter configured to communicate with each other over a selected channel of the plurality of channels based upon communication interference detected on one or more channels, wherein the receiver is configured to switch to the selected channel from a previously selected channel of the plurality of channels after a new channel detection phase detects the selected channel and the communication interference is detected on the previously selected channel.
A method of sealing an opening comprising a curtain configured to seal the opening, the curtain controlled by an operator coupled to a receiver, the receiver configured to communicate with at least one transmitter on a wireless network having at least a first channel and a second channel, the method comprising the steps of:
- receiving, via the receiver, a first signal from the at least one transmitter on the first channel;
- switching, via the receiver, from the first channel to the second channel when a wireless interference is detected by the operator on the first channel, wherein the switching from the first channel to the second channel comprises the steps of:
- determining a number of first communication retries associated with the first channel and a number of second communication retries associated with the second channel;
- comparing the number of first communication retries with the number of second communication retries;
- and
- communicating with the at least one transmitter on the second channel if the number of first communication retries is greater than the number of second communication retries by a predetermined amount of retries;
- receiving, via the receiver, a second signal from the at least one transmitter on the second channel;
- and
- moving, via the operator, the curtain based on the second signal.
