Problems solved by technology
However, with the continuous addition of metering devices, the information collected by the metering devices needs to be stored in the PI database, and PI points are used to store the collected information in the PI database, so it is necessary to continuously add PI point information. Currently, there are More than 2 million, which undoubtedly increases the workload of PI point maintenance based on the PI database. Moreover, manual maintenance of PI point information has certain errors in accuracy and completeness, which cannot meet business needs
On the one hand, the maintenance workload of PI points is unsustainable; on the other hand, the information in the database is missing, resulting in a continuous decline in data quality

The invention discloses a PI point automatic maintenance method and device based on a business system. The method includes: collecting measurement point information of the business system, establishing a measurement model according to preset measurement point range rules, the measurement model including at least one measurement point, and a preset number of measurement points contained in each measurement point Information; set the PI point object corresponding to the measurement point information in the PI database, when the measurement point or measurement point information of the measurement model is updated, create and update the measurement point in the PI database The PI point object corresponding to the information; detect the real-time data of the metering point according to the preset time period, and write the real-time data of each metering point into the PI database. By adopting the invention, the data of the database can be provided with real-time performance, thereby ensuring the accuracy of the information of the database, making the data of the database complete, and greatly enhancing the quality of the database.
Description
technical field [0001] The invention relates to data information maintenance technology, in particular to a method and device for automatic maintenance of PI points based on a business system. Background technique [0002] PI (Plant Information System) system is a plant data integration and application platform. As the bridge connecting the bottom control network of the power plant and the upper management information system network, PI plays a special and important role in the information integration (integration of management and control) of the power plant. On the one hand, PI is used for automatic collection, storage and monitoring of power plant data. As a large integrated database and historical database, PI can store years of data for each process point online. It provides a clear and precise picture of the operation situation, and the user can browse the current production situation of the power plant and review the past production situation. It can be said that P...
