The present invention relates to a communications channel automatic setting method for preventing communications interference in a wireless individual room control system. Especially, the method comprises the following steps: sequentially storing a plurality of usable communications channel frequencies at each preset time period in a central room controller; determining whether the radio signal intensity on the usable communications channel frequencies is stored by being read to the determined number; calculating an average value of the read and stored radio signal intensity on the usable communications channel frequencies after sequentially reading and storing the radio signal intensity on the usable communications channel frequencies to the determined number; finding a channel having the lowest average value of the radio signal intensity due to having the best receiving sensitivity among the calculated average value of the radio signal intensity on the usable communications channel frequencies; deciding the channel having the lowest average value of the radio signal intensity as an optimized communications channel frequency; and automatically changing the decided relevant communications channel frequency to the wireless communications channel frequency between the central room controller and individual room controllers, and between the central room controller and a controller. |
