Problems solved by technology

At present, underground power line communication can only transmit working data with a small amount of data. How to ensure the transmission of data with a large amount of data such as music and video while the power line is transmitting work data with a small amount of data is a problem that needs to be solved.

Abstract

The invention provides a power line carrier communication method, comprising the following steps: encoding to-be-transmitted data by a sender, wherein the to-be-transmitted data comprise operational data and non-operational data; allocating communication bandwidth for the operational data and the non-operational data in the encoded to-be-transmitted data dynamically; coupling the encoded to-be-transmitted data to a power line and sending the encoded to-be-transmitted data in the allocated communication bandwidth to a receiver by the power line; and receiving the encoded to-be-transmitted data by the receiver and decoding and processing the encoded to-be-transmitted data. The invention also provides a sending device and a mine media player data used by the method. According to the invention, the utilization rate of the power line communication bandwidth is improved effectively, and high-capacity non-operational data are transmitted at the same time of ensuring the transmission stability of the operation data in a long-distance communication process.

Description

technical field [0001] The invention relates to the field of power line communication, in particular to a method of power line carrier communication, a sending device used in the method, and a playing device for playing media in underground mines by using the method. Background technique [0002] The power line is an extremely unstable data transmission channel with high noise and strong attenuation. Power line communication technology (PowerLine Communication, PLC) appeared in the 1920s and developed rapidly in recent years as a new communication technology using power line network as a carrier. The use of power lines for data transmission has the advantages of high channel reliability and reasonable routing. Due to the wide distribution and scale of power lines, it is the only wired communication method that does not require line investment. [0003] At present, before the high-voltage and medium-voltage power line technologies are mature, low-voltage PLC technology and o...
