High-speed power line carrier device used for transmitting digital signals

Abstract

The invention discloses a high-speed power line carrier device used for transmitting digital signals. The high-speed power line carrier device used for transmitting the digital signals comprises an analog front end modulation-demodulation chip, a digit rear end processing chip and a power line carrier transformer. The analog front end modulation-demodulation chip demodulates data signals from a power line, then transmits the data signals to the digit rear end processing chip for processing, and finally sends the data signals to a central processing module through an MII interface for analysis. The central processing module sends the data signals to the digit rear end processing chip through the MII interface for processing, then the data signals are transmitted to the analog front end chip, and the data signals are modulated on the power line. Modulation and demodulation of the data signals are achieved through the fact that the power line carrier transformer couples the data signals on the power line. According to the high-speed power line carrier device used for transmitting the digital signals, a system can be installed through existing power lines of a field, rewiring is not required, installation efficiency is improved, and user cost is saved.

Description

technical field [0001] The invention relates to a system for transmitting audio signals through power lines and controlling the access and play of the audio signals, and in particular to a high-speed power carrier device for transmitting digital signals. Background technique [0002] With the improvement of life, people's love for music has gradually become an indispensable part of life. At home, in hotels, and in other public places, people not only hope to hear music anytime and anywhere, but also hope to enjoy their favorite music conveniently. . [0003] At present, the building audio system adopts the audio line connection scheme, and some adopts the wireless radio frequency scheme. They all have their own defects: using the audio cable connection scheme, it is necessary to re-stretch a very long connection in the actual arrangement, and the attached power adapter must be connected externally. Once the position is changed, it is very inconvenient to re-arrange. On the...

Problems solved by technology

They all have their own defects: using the audio cable connection scheme, it is necessary to re-stretch a very long connection in the actual arrangement, and an external power adapter must be connected. Once the position is changed, it is very inconvenient to arrange again.

However, this technology has not been used in building audio transmission systems at present, so it cannot solve the problem of rewiring in audio systems
