Method and device for identifying node affiliation transformer area

Abstract

The embodiment of the invention discloses a method and a device for identifying a node affiliation transformer area, the same transformer area comprises a concentrator and a plurality of electric meter nodes, the nodes are in direct or indirect communication with a power line carrier of the concentrator to form a topological network, a first domain address of the concentrator of each transformer area is unique, the method is applied to the concentrator. The method includes: receiving a node deletion request, wherein the node deletion request carries a fourth domain address and a node address of the node requested to be deleted; if the fourth domain address is consistent with the first domain address, deleting the node of which the node address recorded in a node database pre-stored in the concentrator is consistent with the node address of the node requested to be deleted; and receiving a node joining request, wherein the node joining request carries a fifth domain address and the node address of the node requested to join.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a method and a device for identifying a station to which a node belongs. Background technique [0002] The on-site network of the power carrier automatic meter reading system is a centralized network, and the physical topology of the on-site network is a tree structure. A concentrator is installed under the distribution transformer, and multiple nodes (nodes are electric meters, generally tens to hundreds) are discrete Every household distributed within 1 km from the concentrator, such as figure 1 As shown, it is a field network topology diagram of a power carrier meter reading system, where the graph M represents the electric meter. [0003] The power line carrier is used for communication between the concentrator and each meter. The concentrator needs to enter the meter file belonging to the distribution station area. The concentrator initiates a data collection command for each ...

Problems solved by technology

[0005] In view of the above-mentioned technical problems, the embodiment of the present invention provides a method and device for identifying the stations to which nodes belong, which can accurately determine the wrong nodes in the power carrier meter reading system, and automatically assign these stations to the wrong nodes Automatically belong to the correct station area, which solves the problem that some meters cannot be read or is not readable due to the wrong attribution of the node station area, and avoids the calculation of the line loss of the station area caused by the wrong attribution of the node station area Distortion problem
