DATA TRANSMISSION METHOD, DATA TRANSMISSION SYSTEM FOR REDUCING POWER CONSUMPTION OF CONNECTION APPARATUSES

摘要

PURPOSE: A data transmission method, a data transmission system, and a data transmission apparatus are provided to reduce overall power consumption when using some of connection apparatuses connected to the data transmission system. CONSTITUTION: A data transmission system includes a plurality of data transmission apparatuses interconnected in a ring configuration. Each of the data transmission apparatuses(1) includes a processor(3), for processing transmitted/received data based on a predetermined communication protocol, and a transceiver(2). A first data transmission apparatus generates received data according to a transmission signal outputted from an immediately upstream data transmission apparatus. A second data transmission apparatus generates received data according to a transmission signal outputted from an immediately upstream data transmission apparatus, processes the received data, and outputs the transmission signal to an immediately downstream data transmission apparatus.
