<p><P>PROBLEM TO BE SOLVED: To transmit not only control signals but also monitoring data by one set of radio apparatus without accelerating a communication speed. <P>SOLUTION: A radio transmitter-receiver is provided with a radio master set for transmitting the control signals for controlling a control object and receiving the monitoring data and a radio slave set for receiving the control signals from the radio master set and transmitting the monitoring data relating to the control of the control object to the radio master set. The radio master set transmits and outputs the control signals for the control object, is turned to a reception mode after the lapse of the time required for transmitting the control signals until the next control signal is inputted, and receives the monitoring data from the radio slave set during the reception mode. In the meantime, the radio slave set switches to a transmission mode after receiving the control signals from the radio master set and transmits the monitoring data to the radio master set while the radio master set is in the reception mode. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
