Description

Hydrologic situation analysis and early warning method and system based on low-code configuration Technical Field The invention relates to the technical field of hydrologic information processing and early warning decision making, in particular to a hydrologic situation analysis and early warning method and system based on low-code configuration. Background The traditional hydrologic forecasting system generally relies on professional hydrologic models (such as SCS-CN models and HEC-HMS models) for modeling and calculation, and has higher precision and scientificity, but the configuration process is complex, the professional literacy requirement for users is high, and the requirements of quick deployment and high-efficiency response in basic water service units and sudden emergency scenes are difficult to meet. In recent years, with the rise of technologies such as visual modeling, low-code development, automatic model matching and the like, a hydrological forecasting and early warning system based on a simplified configuration flow gradually becomes a research hotspot. The low-code platform provides a high-efficiency and flexible solution for hydrologic model construction by virtue of the development concept of visual configuration and automatic generation, but most of the existing systems still stay on a general platform level, lack dynamic adaptation capability for the characteristic parameters of the watershed, and the model calling process does not have an intelligent selection mechanism, so that accuracy and adaptability are difficult to maintain under complex and changeable watershed conditions. At present, some researches try to combine a data-driven machine learning method with a traditional hydrologic model to improve the intelligentization degree of model prediction, however, the method often depends on large-scale sample training and long-term data accumulation, and the effect is obviously reduced under the condition of insufficient data or obvious regional characteristic difference. Meanwhile, most of the existing hydrologic early warning systems lack uniform configuration standards and modularized interfaces, so that the systems are difficult to migrate and high in maintenance cost. In the aspect of model adaptation, the traditional method is generally manually selected by an expert, is time-consuming and is easily influenced by subjective judgment, and lacks objectivity and generality. In addition, in the aspect of hydrologic situation index construction and early warning trigger mechanism, the existing method mostly adopts single parameters or static rules, is difficult to comprehensively reflect the overall risk situation of the river basin, and does not have flexible early warning strategy adjustment capability. Therefore, a low-code hydrologic situation analysis system capable of realizing automatic model matching, parameter standardization processing and flexibly configuring early warning rules is urgently needed to realize more efficient and universal hydrologic forecasting and early warning capability. In summary, the existing hydrologic situation analysis and early warning technology has the problems of complex model configuration, poor suitability, low deployment efficiency, rigid early warning mechanism and the like. The invention provides a hydrologic situation analysis and early warning method and system based on low-code configuration, which adopts a standardized drainage basin feature vector construction method and a model automatic matching mechanism, effectively improves the universality and deployment efficiency of the system, and solves the problems of high professional threshold and response lag in the hydrologic model configuration and situation judgment process. Disclosure of Invention The invention is provided in view of the problems of complex configuration, weak model adaptation capability and poor flexibility of an early warning mechanism of the existing hydrological model. Therefore, the problem to be solved by the invention is how to realize the intelligent adaptation of the hydrological model facing different flow domain characteristics by a low-code visual configuration mode, and to perform situation index calculation and hierarchical early warning by combining real-time monitoring data, so as to construct a hydrological situation analysis and early warning system which is flexible in configuration, efficient in deployment and timely in response.
