COMMUNICATION PROTOCOL FOR A RADIO-FREQUENCY LOAD CONTROL SYSTEM

摘要

A radio-frequency (RF) load control system (100) allows for the expedient transmission of subsequent digital messages to one or more recipients via an RF communication link. The control system (100) comprises at least one load control device for controlling the amount of power delivered to an electrical load (104, 106) in response to a received digital message. Each control device of the load control system (100) is operable to interrupt the propagation of a first digital message to transmit a second digital message in response to determining that the second digital message has a high priority than the first digital message. For example, an originating control device (130) may transmit first and second digital messages in response to a press and a release of an actuator (114, 116), respectively, and may interrupt the propagation of the first digital message to transmit the second digital message if the first digital message is irrelevant in view of the second digital message.
