Dynamic networking method and communication component

Abstract

The invention relates to a dynamic networking method and a communication component. The communication component comprises an intelligent transceiver and a control module. The control module comprises a network contention avoidance unit and a repetitive data packet detecting and discarding unit, wherein the network contention avoidance unit is used for setting a random transmission time to a data packet to be transmitted according to a channel idle state information on a power line intercepted by the smart transceiver; and the repetitive data packet detecting and discarding unit is used for analyzing the data packet on the power line received from the intelligent transceiver and discarding the newly-received data packet when the received data packet is processed in advance. In the invention, when a plurality of terminals communicate with each other on the power line, intelligent transfer on the communication component is controlled by the dynamic networking technology, thereby greatly improving the capability of the whole system to resist attenuation of the power line and resist complex noise of the power line, obviously shortening the communication time among the communication terminals, and improving the real-time of communication and the stability of the system.

Description

technical field [0001] The invention relates to a dynamic networking technology of power line carrier communication, which is suitable for reliable communication of intelligent terminals on power lines, and in particular relates to a dynamic networking method and communication components realized in a power line network with less data transmission. Background technique [0002] The power line carrier communication uses the existing AC power line as the communication line, and uses the power line carrier technology to realize the transmission of data signals, which saves the wiring project and can significantly reduce the networking cost of the intelligent network. Therefore, the power line communication has become an automatic meter reading technology. The development direction of the downlink communication channel. Compared with the traditional manual meter reading technology, the automatic meter reading technology (Automatic Meter Reading, AMR) that uses the power line car...

AI Technical Summary

Problems solved by technology

Due to the strong randomness of the severe dynamic changes of the load, interference, and attenuation of the low-voltage power grid, it is difficult to adapt to this change even if the optimized historical relay path or the division and optimization of the station area

For example, in the process of automatic meter reading using the "learning" mode of the concentrator, the downstream path of the meter reading command is the same as the upstream path of the corresponding metering data of the meter reading command. When a node in the meter reading path fails , will cause the failure of the meter reading process

Although the automatic meter reading system using the "networking" mode has introduced CSMA technology, the actual network conflict handling is not ideal, and there are still defects such as network congestion.

[0007] (2) The meter reading time is long, which cannot meet the real-time requirements of meter reading

The long meter reading time cannot meet the real-time requirements of meter reading, and cannot realize the real-time control function of users who owe electricity bills, and cannot monitor users who steal electricity

In the "networking" mode, every time a fault table appears or a new table is added, the system needs to re-network, which takes a long time

[0008] (3) Inconvenient maintenance and high cost

In the "networking" mode, every time a fault table appears or a new table is added, the system needs to be re-networked, which increases the difficulty of system maintenance and increases the cost of system maintenance
