Abstract

The invention discloses a method and system for automatically searching meters. The method sends a meter search command and receives meter state information fed back by the meter according to the meter search command; Verify and judge whether the meter status information conforms to the distribution line message specification; after the reporting time period ends, send configuration port commands to the meters whose meter status information has passed the verification and conform to the distribution line message specification, and complete Meter registration; if the meter status information does not conform to the distribution line message specification and / or the content verification fails, set the node communication flag and resend the meter search command until all meters have completed meter registration, or The number of times the table search command is sent reaches a preset search threshold. By implementing the invention, the problem that the master node cannot search for the mounted meter to collect meter data when the unique identification information of the slave node cannot be specified in advance is solved.

Description

technical field [0001] The invention relates to the field of power distribution, in particular to a method and system for automatically searching meters. Background technique [0002] In the process of data collection based on one-to-many, for example, when using a field operator to check threads or using a concentrator in the data collection network to search for each meter, the master node needs to specify the unique identification information of the slave node in advance, In order to achieve one-to-one communication, and then collect data information from the nodes. [0003] However, in actual scenarios, it is sometimes impossible to specify the unique identification information of the slave node in advance. At this time, the master node cannot search for the mounted meters to collect meter data. Therefore, in the data collection network, how to automatically establish the communication relationship between the master node and the slave node is of great significance to i...
