Embodiment Construction

[0064] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0065] The innovative idea of ​​the present invention is: firstly establish a hydropower plant equipment object knowledge base, collect multi-level feature dictionaries of equipment object attributes, and then carry out word segmentation for the monitoring system measurement point description, and use the multi-level forward maximum matching algorithm to describe Extract the feature information from, and finally identify the device object to which the measuring point belongs through keyword matching, and establish a device object tree. The method for automatically establishing an object tree of the present invention further improves the digital level and operation management level of the hydropo...

Abstract

The invention discloses a method and device for automatically establishing an equipment object tree for a hydraulic power plant monitoring system. The method comprises the steps of firstly collectinga multi-level feature dictionary of equipment object attributes, then performing word segmentation on monitoring system measurement point description to extract feature information from the measurement point description, and finally identifying equipment objects to which measurement points belong through keyword matching, and performing organizing to form an equipment object tree. According to themethod and device, the maintenance work efficiency is improved, the practicability is high, the digitization level and the operation management level of the hydropower station are further improved, popularization and development of professional advanced application are promoted, and the method and device play a positive role in promoting development of intelligent hydraulic power plant construction.

Description

technical field [0001] The invention belongs to the technical field of hydropower plant monitoring, and in particular relates to a method and device for automatically establishing an equipment object tree for a hydropower plant monitoring system. Background technique [0002] The monitoring system of hydropower plants has long used the method of monitoring the changes of basic IO measuring points to reflect the operation of on-site equipment. With the continuous expansion of data scale, more and more equipment action information, it is more difficult for operators to find important events from relevant information. Large, increasing the screen monitoring burden of operating personnel. By establishing equipment objects and filtering unnecessary event information according to the object mechanism, it has become the development direction of the monitoring system of hydropower plants. However, the device object model of most monitoring systems is established manually, that is, ...
