Embodiment 1
[0123] Embodiment 1 Association analysis of safety monitoring data
[0124] (1) Combing and analysis of safety monitoring data
[0125] For dam safety monitoring data (such as dam deformation, seepage pressure, seepage volume, earth pressure, etc.), carry out preprocessing work before analysis, mainly to clean and verify the data, delete duplicate information in the data, and correct Existing errors ensure data consistency and remove white noise in blank data domains and knowledge backgrounds.
[0126] According to the project requirements, divide the preprocessed safety monitoring data into different data sub-items, and divide the monitoring data into sub-items according to the type of monitoring data for each category of data, and divide the data in each sub-item Preliminary sorting is carried out in the form of time series from far to near.
[0127] After the preliminary sorting, the data were subjected to exploratory data analysis (EDA), and the basic attributes and dist...
Embodiment 2
[0148] Embodiment 2 The dam safety performance intelligent prediction model based on SVR is constructed, such as figure 2 shown
[0149] (1) Selection of predictors
[0150] Based on the optimal forecast period determined in embodiment 1, according to the correlation coefficients of each monitoring data item and the safety performance index on this forecast period, the correlation coefficients are arranged in order from large to small, and analyzed in pairs Monitor the correlation between data items, remove one of the two with a cross-correlation coefficient greater than 0.4, and use the selected monitoring data item as the final selection predictor.
[0151] (2) Construction of PSO-SVR model
[0152] The particle swarm optimization algorithm is used to search for the optimal solution of the parameters C, σ and ε of the SVR, and the construction steps of the model are shown in the figure. The specific steps are:
[0153] Step1-determine the predictor;
[0154] Step2- Org...

Abstract
The invention discloses a hydraulic engineering monitoring system based on three-dimensional display. The system comprises a power station control system, an upper computer, a cloud server and a terminal device. The power station control system comprises a power station data receiving management module, and a data acquisition device, a water regime monitoring module, an information query module, an alarm module and a display respectively communicated with the power station data receiving management module. A BIM model construction module is arranged in the power station data receiving management module and used for loading a BIM model of the hydraulic structure and BIM models of all monitoring instruments and reconstructing a three-dimensional BIM model of the hydraulic structure. A powerstation cluster control system and a platform management system are operated on the terminal device. The power station data receiving management module communicates with an upper computer. The upper computer is in communication with the cloud server, and the cloud server is in communication with the terminal device. By the adoption of the hydraulic monitoring system, the safety state of hydraulicstructures such as dams and workshops can be visually displayed.
Description
technical field [0001] The invention belongs to the technical field of hydraulic monitoring systems, and relates to a hydraulic monitoring system based on three-dimensional display. Background technique [0002] Three-dimensional data measurement technology is an important topic in the field of computer vision, and has a wide range of applications in virtual reality, cultural relic protection, machining, film and television special effects production, computer simulation, clothing design and other fields. At present, it is rarely used in the field of hydraulic monitoring. The existing hydraulic monitoring system cannot visualize the safety status of hydraulic structures such as dams and workshops. Compared with non-professionals, it is difficult to quickly obtain intuitive visual simulation diagrams, and it is difficult to accurately judge the monitoring results of hydraulic structures. Therefore, it is necessary to develop a hydraulic monitoring system based on three-dime...
