Network communication node for power line communication network and data transmission method for same

Abstract

The invention provides a network communication node for a power line communication network and a data transmission method for the same. The network communication node can be used for receiving broadcast messages from a gateway, judging whether the overall load of the power line communication network is changed or not according to the broadcast messages, and dynamically changing routing paths of data transmission according to the content of the load change if the overall load of the power line communication network is changed.

Description

technical field [0001] The invention relates to a network communication node for a power line communication network and a data transmission method thereof. More specifically, the network communication node and data transmission method of the present invention can dynamically change the routing path of data transmission according to the load of the power line communication network. Background technique [0002] In response to various information transmission requirements, many heterogeneous networks have been developed, among which the most important one is the power line communication network (PLC). In detail, the power line communication network mainly digitizes the information to be transmitted and then transmits it through the existing power line. The advantage of transmitting signals in this way is that it does not require additional network wiring, and the area covered by the power line The wide range is an advantage that other networks cannot achieve.

Problems solved by technology

[0003] Although the power line communication network has the aforementioned advantages, it still encounters the influence and limitation of other factors on the transmission of data.

Specifically, the impact on the power line communication network is mainly due to: 1. The electrical equipment on the power line communication network generates a high degree of noise when using the power line; Third, because the use status of the power line communication network is highly time-varying, it is easy to cause the instability of the carrier signal during transmission

Accordingly, if the route determination method of the traditional network, such as route discovery or device discovery, is used to determine the route of data transmission in the power line communication network, too much time will be wasted. Time and network resources make the routing path determination of the power line communication network inefficient at all
