INTERMITTENT RECEPTION TYPE COMMUNICATION EQUIPMENT

摘要

PURPOSE:To receive sent message without any omission while reducing the power consumption. CONSTITUTION:This equipment is equipped with a transmitter 1 which performs transmission at specific-period transmission timing and a receiver 2 which performs wait reception at the transmission timing. The transmitter 1 is equipped with a transmission timing generation part 13 which obtains the transmission timing and a transmission control part 12 which performs transmission at transmission timing just after the generation of a request-to-send trigger when the request-to-send trigger is generated. The receiver 2 is equipped with a reception timing generation part 24 which obtains reception timing according to the transmission timing and a wait control part 25 which performs wait reception only in a specific period that is shorter than a specific period and includes the transmission timing at each specific period on the basis of the reception timing generation part 24. Further, the transmitter 1 is equipped with a maintenance signal sending-out part 15 which sends a maintenance signal at timing of a period that is specific integral multiple of the specific period, and the receiver 2 is equipped with a start-stop control part 23 which synchronizes the reception timing generation part 24 with the transmission timing generation part 13 on the basis of the maintenance signal.
