The invention is further described below with reference to the drawings and examples.
Examples:
a method for finely managing and controlling a distribution network maintenance plan based on work order data is shown in fig. 1, and comprises the following steps:
receiving an overhaul application form, extracting the content of the overhaul application form, acquiring corresponding work order data, demarcating a network distribution area for maintenance based on the work order data, and calling topology data of the network distribution area for maintenance;

and obtaining maintenance constraint conditions, and carrying out maintenance planning according to the maintenance constraint conditions, the maintenance flow and equipment to be maintained in each maintenance link in the maintenance flow.
The maintenance application form comprises a distribution network area, maintenance requirements and maintenance purposes, when maintenance planning is carried out, a specific maintenance flow can be determined based on the maintenance requirements and the maintenance purposes, and then the maintenance links of the maintenance flow are divided according to time sections.
The content extraction can be achieved by means of text recognition or the like.
When the maintenance constraint conditions are obtained and maintenance planning is carried out according to the maintenance constraint conditions, the maintenance flow and equipment to be maintained in each maintenance link in the maintenance flow, the maintenance planning is carried out for the first time on the basis of the maintenance scheduling regulation and the power grid safe operation requirement, the maintenance planning is carried out for the first time on the basis of the maintenance constraint conditions, and the maintenance constraint conditions which are carried out for the second time are obtained according to the specific operation condition of the power grid, such as equipment constraint, construction period constraint and the like, so that the planning efficiency of the maintenance planning is further optimized.
After the basic data corresponding to the distribution network area for maintenance is obtained, the basic data are classified according to the external interface types, the corresponding basic data are respectively subjected to data verification according to the classification result, the basic data passing the data verification are subjected to format conversion, and various basic data are integrated into a unified data format.
The external interface comprises a power generation plan supporting system, a dispatching automation system, an overhaul ticket management system, a dispatching information management system and the like.
In the process of converting the format of the basic data passing through the data verification, various basic data of the same equipment are subjected to matching mapping based on the equipment name, and various basic data belonging to the same equipment are integrated according to the matching mapping result.
Because the data of different types generated by the same equipment can be acquired through different information acquisition systems, the data types acquired by the different information acquisition systems are inconsistent, and the efficiency of subsequent overhauling analysis on the equipment can be improved after the different data of the same equipment are integrated.
The basic data comprise equipment account data, power grid equipment fixed inspection information, an annual calendar history inspection plan, a monthly calendar history inspection plan, equipment information to be eliminated and familial defect equipment information.
