Automatic monitoring system for grouted rubble arch dam

Abstract

The invention provides an automatic monitoring system for a grouted rubble arch dam. The automatic monitoring system comprises a data acquisition module, a data center library module and an arch dam safety monitoring, analyzing and early warning module. The data acquisition module comprises a water level sensor, a temperature sensor and a dam body radial displacement monitoring module; the data center library module is used for storing historical data generated by the data acquisition module and the arch dam safety monitoring, analyzing and early warning module; and the arch dam safety monitoring, analyzing and early warning module performs threshold judgment on the monitoring data transmitted by the data acquisition module through a multiple linear regression method and/or an LSTM methodand/or a Gaussian process regression method and/or a convolutional neural network method so as to determine whether early warning information is sent or not. According to the method, a dam safety inversion model and a prediction and evaluation early warning system of the grouted rubble arch dam are provided, the structure checking time can be pushed to the second-level response through the application of an artificial intelligence method, and a new path is opened up for real-time safety evaluation and prediction early warning analysis of the dam.

Description

technical field [0001] The invention belongs to the field of reservoir dam safety monitoring, and in particular relates to an automatic monitoring system for masonry arch dams. Background technique [0002] With the rapid development of science and technology and the actual demand for the safe operation of reservoir dams, most reservoir dams have problems such as long operation time, serious aging and disrepair, and risks in dam structure and seismic safety. In order to ensure the safe operation of reservoir dams , Safety monitoring is an important part of reservoir management, an important means to grasp the safety behavior of reservoir dams, and a prerequisite for scientific scheduling and safe operation. [0003] For mountainous and hilly areas, where the terrain is relatively narrow, arch dams are preferred and widely selected as water-retaining structures because of their spatially shell-like high-order statically indeterminate structures; from a safety perspective, the...

AI Technical Summary

Problems solved by technology

[0003]For mountainous and hilly areas, the terrain is relatively narrow, and arch dams are preferred and widely selected as water-retaining structures because of their spatial shell-like high-order statically indeterminate structures; from the perspective of safety From a perspective, the construction of a dam safety monitoring system is a rigid need for dam operation. It is an inevitable trend for the water conservancy industry to grasp the safety level of the dam during the operation period and discover existing problems and potential safety hazards in a timely manner. It is an advantageous platform for effectively monitoring the working status of the dam ; From an economic point of view, the construction of a dam safety monitoring system can realize real-time monitoring and greatly reduce the possibility of a series of internal and external factors causing dam failures; in actual operation, because the existing monitoring system does not have a real-time safety early warning system, It can realize the automatic collection and real-time processing of all data, but cannot satisfy the automatic control of electrical equipment, resulting in poor integration between systems, resulting in the inability to realize data interconnection and sharing, and redundant and complicated data resources, so that the management cannot grasp the actual situation of the dam in time. Affect the specific scheduling of dam work under unfavorable conditions such as typhoons, heavy rains, floods, and high water levels. In severe cases, the dam will fail and endanger downstream safety

[0004]Because there are currently no dam safety evaluation standards, model algorithms and real-time safety evaluation and early warning systems for masonry arch dams, it is impossible for management to schedule dam work in a timely manner Make a timely response, and non-intelligent data collection more or less affects the process of data transmission, and cannot process data in real time. There is no doubt that this has caused a huge risk to ensure the safe operation of the reservoir dam
