Abstract

The invention provides an intelligent substation secondary equipment information collection method. The method comprises: naming substation secondary equipment and parts in the secondary equipment according to preset naming principles and identifier specifications, and storing identifier information of the named secondary equipment and the named parts of the equipment in a database; setting two-dimensional code tags for the secondary equipment, wherein the identifier information of the secondary equipment and the parts of the equipment is coded by adopting two-dimensional codes; scanning the two-dimensional code tags on the secondary equipment by a mobile terminal to obtain the identifier information of the secondary equipment; comparing the obtained identifier information with identifier information in the database, and if the identifier information is the same, continuing to collect a two-dimensional code tag of next secondary equipment; and if the identifier information is not the same, modifying the identifier information in the database. The method is used for analyzing and managing intelligent substation secondary equipment information, so that the problem of high workload of operation and maintenance personnel caused by an increase in equipment quantity is effectively solved.

Description
