RADIO DATA TRANSMISSION SYSTEM

摘要

PURPOSE:To enhance the reliability of data transmission without making circuit configuration complicated. CONSTITUTION:Operating data representing the operating state of a lighting fixture A are sent from a controller B to an operation equipment C and a display section 24 of the operation equipment C displays the operating state of the lighting fixture A. The controller B sends the operating data intermittently for a prescribed period in a radio system. A timer 23 counting the period of the intermittent transmission is operated synchronously with a reception point of time of the operating data from the controller B. A reception processing section 21 sets a radio section 20 into the intermittent reception enable state of the operating data based on the intermittent transmission period counted by the timer 23. A transmission processing section 22 allows the radio section 20 to send a control command to the controller B for a period when the controller B is not in the transmission state based on the intermittent transmission period counted by the timer 23.
