Problems solved by technology

However, because the power line is not fixed, there are many nodes and branches, the types of equipment are complex, and there are various interference signals, the carrier communication is often affected and cannot communicate reliably.
Although short-distance wireless communication will not affect communication due to the layout

Abstract

The invention discloses a multi-mode communication device and a multi-mode communication method. The multi-mode communication device comprises a processor, a first communication unit used for short-distance wireless communication, a second communication unit used for transmitting a narrow-band carrier signal and a broadband carrier signal and a power line isolation coupling unit, wherein the processor is used for sending first data to the first communication unit and the second communication unit; the first communication unit is used for modulating received first data sent by the processor to second data and sending the second data; and the second communication unit is used for respectively modulating the received first data sent by the processor to third data and fourth data and sending the third data and the fourth data to a power line through the power line isolation coupling unit, and a power line narrow-band carrier communication mode, a power line broadband carrier communication mode and a short-distance wireless communication mode are combined together.

Description

technical field [0001] The invention relates to a device for digital communication using wireless and power lines, in particular to a multi-mode communication device and a multi-mode communication method. Background technique [0002] In the fields of power meter reading, industrial communication and smart home, power line carrier and short-distance wireless communication are widely used. [0003] Carrier communication can be realized by using power lines, in which narrowband carrier communication has a single frequency point, narrow signal spectrum, and low transmission rate, but using a lower carrier frequency can transmit a longer distance on the power line. Broadband carrier uses digital multi-carrier frequency division multiplexing technology to realize multi-carrier parallel communication, with high transmission rate, but short power line transmission distance. Power line narrowband and broadband carrier communication technologies have been widely used in fields such ...
