Abstract

The invention discloses a dual-mode communication network system and a communication mode selection method thereof. The communication mode selection method comprises the following steps: enabling a PCO to receive an SOF data frame sent by STA equipment; judging whether the length of the SOF data frame is smaller than 16 bytes or not; if so, adopting a second communication mode determination mode to determine a communication mode for replying the ACK frame; and if the length of the SOF data frame is not smaller than 16 bytes and the receiving buffer area is full of the received data, determining a communication mode of replying the ACK frame by adopting a first communication mode determination mode. The embodiment of the invention has the advantages that the STA station reduces the time forwaiting for the ACK frame, and improves the retransmission efficiency and transmission timeliness of the data frame.

Description

technical field [0001] The invention belongs to the technical field of broadband power line carrier communication, and in particular relates to a dual-mode communication network system and a communication mode selection method thereof. Background technique [0002] In recent years, with the nationwide transformation of the power grid, how to solve the problem of automatic management of the increasingly large power supply network is imminent. There have been a large number of automated centralized meter reading technologies, among which power line carrier is one of the mainstream technologies. [0003] Because the low-voltage power network has the characteristics of complex structure and random interference, the traditional PLC (Power Line Carrier) meter reading technology has problems such as low reliability and untimely meter reading. With the evolution of various communication technologies, centralized meter reading using dual-mode communication has become a trend, and th...
