Configuring communications for a load control system

摘要

A load control system may include multiple control devices that may send load control messages to load control devices for controlling an amount of power provided electrical loads. To prevent collision of the load control messages, the load control messages may be transmitted using different wireless communication channels. Each wireless communication channel may be assigned to a load control group that may include control devices and load control devices capable of communicating with one another on the assigned channel. A control device may send load control messages to a load control device within a transmission frame allocated for transmitting load control messages. The transmission frame may include equal sub-frames and load control messages may be sent at a random time within each sub-frame. Control devices may detect a status event within a sampling interval to offset transmissions from multiple control devices based on detection of the same event.

1. A load control system configured to send load control messages from a plurality of control devices, and wherein each load control message is transmitted for controlling an amount of power provided to an electrical load, the load control system comprising:
a first load control group that includes at least one control device configured to send load control messages on a first wireless communication channel for controlling an electrical load; a second load control group that includes at least one control device that is a same type of control device as the at least one control device of the first load control group, and wherein the at least one control device of the second load control group is capable of causing interference with the load control message transmitted by the at least one control device of the first load control group by sending a respective load control message on the first wireless communication channel, wherein the second load control group is configured to transmit on a second wireless communication channel to avoid the interference with the load control messages from the at least one control device in the first load control group; and a third load control group configured to transmit load control messages on the first wireless communication channel, and wherein the first load control group and the third load control group are separated by a plurality of other load control groups that are configured to communicate load control messages on a plurality of other wireless communication channels to avoid interference between the load control messages of the first load control group and the load control messages of the third load control group.
