Abstract

The invention discloses a method and a system for automatically searching a meter. The method comprises the following steps: sending a meter searching instruction and receiving meter state informationfed back by the meter according to the meter searching instruction; performing content verification on the meter state information according to a preset verification rule, and judging whether the meter state information conforms to a distribution line message specification or not; after the reporting time period is finished, sending a port configuration instruction to the meters which pass the meter state information verification and accord with the distribution line message specification to finish meter registration; and if the meter state information does not accord with the distribution line message specification and / or the content verification is not passed, setting a node communication mark, and resending the meter search instruction until meter registration of all meters is completed or the sending frequency of the meter search instruction reaches a preset search threshold. By implementing the method and the device, the problem that the master node cannot search the mounted meter to acquire the meter data when the unique identification information of the slave node cannot be indicated 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 for meters.Background technique[0002]In the process of data collection based on one-to-many, for example, when using an on-site handheld operator to check threads or using a concentrator in the data collection network to search for each meter, the master node needs to clearly 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 node.[0003]However, in actual scenarios, sometimes the unique identification information of the slave node cannot be specified in advance. At this time, the master node cannot search for the mounted meter 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 improve...
