Abstract
The present invention provides a radio controlling apparatus that performs a change to a vacant channel rapidly to allow smooth control even if an uncontrollable state due to radio interference suddenly occurs. In a radio controlling transmission apparatus of the radio controlling apparatus, a reception section for searching a vacant channel is provided. When a vacant channel is detected, it is stored in memory of the radio controlling transmission apparatus. A transmission section transmits control signals, a selection code, and vacant channel data, the control signals being output by an operation section using a control signal transmission timer and a selection code transmission timer. Using a reception section, a controlled apparatus of the radio controlling apparatus receives signals. If the vacant channel data and the selection code are received, the controlled apparatus stores them in memory of the controlled apparatus. If control signals are also received, the control signals are sent to a controlled section via a decoder. However, if the selection code is not received by the controlled apparatus for the duration of a selection code holding timer, control abnormality is determined to have occurred. A visible abnormal operation is performed and a reception channel of the controlled apparatus is changed to the vacant channel stored in the memory of the controlled apparatus. In the radio controlling transmission apparatus, a change to the vacant channel is performed and the selection code is transmitted. When the selection code is detected by the controlled apparatus, control of the controlled apparatus is performed using the vacant channel thereafter.
