WIRELESS LOCAL TRANSMISSION SYSTEM

摘要

PURPOSE:To prevent an erroneous operation due to plural transmission signals produced at the time of operating an optical wireless operating device once by receiving an optical wireless signal, performing the time delay operation for a prescribed time in case of storing the address data of terminal equipment and making the operation data of the same address received within the time invalid. CONSTITUTION:The optical wireless signal is received by the receiving part 7 of an optical wireless repeater 5 and the address data and the operating data are detected. A master machine 1 recognizes that an illumination load 3 operates and returns a processing completion signal including the address data of the terminal equipment 2 to the optical wireless repeater 5. When the address data of this processing completion signal is stored in an address data memory part 9, a timer 11 is set to start the limiting time operation. When the optical wireless signal transmitted from the optical wireless operating device 6 is received by the receiving part 7, it is compared with the address data stored in the address data memory part 9 in a comparison part 10. Since the both address data naturally coincide, the comparison part 10 makes the operating data of the receiving part 7 invalid.
