Abstract

The invention provides an indoor audio calling system using a power line, comprising a PLC (Programmable Logic Controller) gateway and at least one audio calling terminal, wherein the audio calling terminal is connected with the PLC gateway by the power line, and the audio calling terminals are connected with one another by the power lines. By using the power lines as signal transmission medium and adopting HomePlug-AV technology, the indoor audio calling system realizes indoor wiring-free bi-directional point-to-point and point-to-multipoint audio calling based on IP framework, and can realize calling control and management through the network.

Description

Technical field [0001] The invention relates to the technical field of intelligent control, and particularly relates to a power line indoor audio call system for audio calls in residences, offices, hotels, hospitals and other occasions. Background technique [0002] At present, the conventional indoor call system has two types: audio and non-audio, but they generally require wiring installation. There are also similar powerline call systems, but not audio calls (such as application number: 201110413667.0). Therefore, it is difficult for the above call system to meet the requirements for occasions that require audio calls and do not have wiring conditions. Summary of the invention [0003] The present invention provides a powerline indoor audio call system, which uses powerline as a signal transmission medium, and adopts HomePlug-AV (a standard developed by the Home Powerline Network Alliance to meet the needs of home digital multimedia transmission) technology to implement an IP ...
