Problems solved by technology

[0004] The present invention provides an intelligent early warning method for dam safety monitoring data, which can effectively solve the current problem proposed in the above background technology. For these abnormal data, manual identification is mainly adopted, or threshold control or statistical model early warning is performed, and then manual processing is performed. , both require a lot of manpower, and experts with professional knowledge and rich experience can identify the cause of abnormal data from it

Embodiment

[0044] Example: such as figure 1 As shown in , an intelligent early warning method for dam safety monitoring data, including early warning model establishment, threshold formulation and interactive early warning;

[0045] Early warning models include:

[0046] a. Build models based on historical monitoring data;

[0047] b. Gross error identification: use logical discrimination, physical discrimination and statistical discrimination to analyze and process the data that shows a large abnormality in value and is obviously contrary to the reasonable value;

[0048] c. Gross error processing: Abnormal data obtained through gross error identification are replaced and supplemented by measurement value reference method, model generation method and algebraic interpolation method, and then these data are used to establish a model;

[0049] d. Preliminary selection of independent variable factor sets: preliminary screening of independent variable factors according to dam structural pa...

Abstract

The invention discloses an intelligent early warning method for dam safety monitoring data. Different early warning models and indicators are established: stepwise regression model, correlation vector machine model, gray system model, the built model can more truly reflect the relationship between independent variables and dependent variables, It has a wide range of applications. According to measuring instruments, measuring point attributes, thresholds, early warning models and indicators, real-time early warning of monitoring data, sending monitoring equipment abnormal warnings to monitoring personnel, or dam safety warnings to dam safety management personnel, and no Experts with professional knowledge and rich experience are needed, the workload is less, the early warning speed is fast, and the early warning results are more accurate and reliable.

Description

technical field [0001] The invention relates to the technical field of dam safety monitoring, in particular to an intelligent early warning method for dam safety monitoring data. Background technique [0002] Reservoir dams are an important infrastructure of the national economy, an important engineering measure to regulate the temporal and spatial distribution of water resources and optimize the allocation of water resources, and an important part of the national flood control and drought relief system and the river flood control engineering system. Reservoir dam safety is not only related to Flood control safety, water supply safety, and food safety are also related to economic, ecological, and national security. In the process of dam safety monitoring, some abnormal data will be generated. These abnormal data may be erroneous data caused by instrument failure, environmental impact or human error, or may indeed be a true reflection of the dangerous situation of the dam. ...
