Title:
LINE TOPOLOGY IDENTIFICATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/127893
Kind Code:
A1
Abstract:
Disclosed by embodiments of the present application are a line topology identification method and apparatus; specifically: each node connected to a line may comprise a communication module and an impedance regulation module; when an impedance regulation module of a target node is not acting, a processing apparatus obtains a first signal attenuation value corresponding to the communication of any other two nodes. When the impedance regulation module of the target node is acting, the processing apparatus obtains a second signal attenuation value corresponding to the communication of any other two nodes, and according to the first signal attenuation value, the second signal attenuation value, and a preset attenuation threshold value, determines the respective box bodies to which the nodes belong. That is, by means of adjusting the impedance regulation module in a node to determine the box body to which each node belongs, it is unnecessary to inject additional current, not only improving the power quality but also reducing the cost of identification.
