Abstract

The invention belongs to the technical field of power line carrier communication, and discloses a self-adaptive power line carrier communication device and a control method thereof. The control methodof the self-adaptive power line carrier communication device comprises the steps that carrier signals are generated and collected; respectively carrying out enhancement and amplification processing,aggregation processing and correction processing on the acquired carrier signals; and transmitting, storing and displaying the carrier signal, and remotely controlling the processing of the carrier signal through the mobile terminal. The phase of the target bit width is decomposed through the carrier signal generation module to obtain the phase of the first bit width and the phase of the second bit width, and the function values corresponding to the phase of the first bit width and the phase of the second bit width are acquired and stored according to the preset function, so that the calculation complexity is reduced; simultaneously opening a port of the low-intermediate frequency carrier and a port of the high-frequency carrier by using a switch through a carrier aggregation module so asto control the low-intermediate frequency carrier and the high-frequency carrier to work simultaneously; and the carrier signal aggregation effect is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of power carrier communication, and in particular relates to an adaptive power carrier communication device and a control method thereof. Background technique [0002] A carrier wave (carrier wave, carrier signal or carrier) is an electric wave generated by an oscillator and transmitted on a communication channel, and is modulated to transmit voice or other information. The carrier frequency is usually higher than the frequency of the input signal, which is a high-frequency signal. The input signal is modulated onto a high-frequency carrier, just like taking a high-speed rail or an airplane, and then it is transmitted and received. The carrier communication device is the physical basis and carrying tool for transmitting information (voice and data). However, the calculation of the carrier signal generated by the existing power carrier communication device is complicated, and the adaptability is poor; at the...
