Multi-channel real-time full-duplex carrier communication machine

Abstract

The invention discloses multi-channel real-time full duplex carrier communication equipment with a self-organizing network transmission function. The multi-channel real-time full duplex carrier communication equipment comprises a network access management device for supplying data support to automatic network access and controlling the multi-channel real-time full duplex carrier communication equipment to be switched from an idle state to a network access state, a network quitting management device for managing a network abnormity and controlling the multi-channel real-time full duplex carrier communication equipment to be switched from an on-line state to the idle state, a frequency point management device which is connected with the network access management device and the network quitting management device and is used for distributing and recycling frequency points, a network management device for performing management and control as well as processing on the network abnormity according to a running state of an internal network, a state machine management device which is connected with a network access flow management device, a network quitting flow management device and the network management device and is pre-set with a state switching mechanism, and a human-machine interaction interface device which is connected with all the devices and can dynamically display parameters, states, a topological structure and an equipment state through a carrier maintenance software tool terminal.

Description

technical field [0001] The invention relates to the field of medium-voltage power distribution, in particular to a multi-channel real-time full-duplex carrier communication machine for power communication. Background technique [0002] Power line carrier communication refers to a special communication method that uses the existing power transmission medium (cable, overhead line) as an information transmission medium to transmit analog or digital signals through a carrier wave. The biggest advantage of the power line carrier is that it can use the power line network as a communication medium, which is the most widely distributed and most economical wired communication resource in the world. [0003] There has been research on power line carrier communication technology abroad for a long time, but due to the different frequency ranges used in various countries, foreign power line carrier products are designed according to the characteristics and structure of the power grid in ...

AI Technical Summary

Problems solved by technology

[0009] At present, the existing distribution automation communication products, including the existing distribution carrier machine products, have greater advantages in networking capabilities, reliability, long-distance non-relay communication, and real-time performance than similar products, but in Channel establishment time, quickly detect channel quality and switch communication frequency, quickly and flexibly establish routing, flexibly select modulation mode according to channel signal-to-noise ratio, low power consumption, smaller size and lower cost, installation and maintenance and network management There are many deficiencies and there is a lot of room for improvement. Therefore, it is necessary to carry out research and development of a newer generation of new carrier machines and quickly industrialize them
