Abstract

The invention discloses a method, a device and a system for power line carrier communication with dynamic adjustable rate. The method at a sending terminal comprises the following steps: acquiring a to-be-sent data packet and dynamically confirming a target information rate; confirming an information frame according to a preset frame structure, wherein the information frame includes an information frame header and information data, the information frame header comprises the target information rate and the information data contains a data packet; performing spread spectrum coding treatment on the information frame header according to a preset minimal information rate and performing spread spectrum coding treatment on the information data according to the target information rate; sending the information frame after the spread spectrum coding treatment to a receiving terminal. According to the method, the receiving terminal can extremely receive the information frame header; the target information rate can be dynamically adjusted according to the condition of a channel, so that the all-weather communication accessibility can be guaranteed; the transmission at different information rates can be dynamically realized under a same bandwidth condition; the bandwidth can be maximally utilized; the communication rate and the success rate can be guaranteed.

Description

Technical field [0001] The present invention relates to the technical field of power line communication, in particular to a power line carrier communication method, device and system with a dynamically adjustable rate. Background technique [0002] Power line carrier communication refers to a communication method that uses power lines to transmit data. Using the existing power line resources for communication can not only meet the communication needs, but also solve the wiring difficulties, and the infrastructure investment and daily maintenance costs are low, so the power line carrier communication technology has high economy, convenience and practicability. However, the original intention of power line design is to complete power distribution rather than data transmission, so for data communication, its channel characteristics are very unsatisfactory. [0003] In the process of implementing the present invention, the inventor found that at least the following problems exist in t...
