Abstract

The invention discloses a dam surface deformation monitoring system and method. The system comprises a plurality of monitoring and sensing units, each monitoring and sensing unit monitors a corresponding monitoring point on the surface of a dam and is used for obtaining first deformation data and obtaining second deformation data through multi-rate Kalman filtering calculation according to the first deformation data; the data processing unit is used for summarizing the second deformation data according to an edge calculation algorithm to obtain third deformation data; and the monitoring center is used for acquiring and displaying the third deformation data. The dam surface deformation data is monitored in real time through the multiple monitoring sensing units, the real-time deformation angle, deformation speed and deformation displacement of the dam surface are obtained based on the multi-rate Kalman filtering fusion edge calculation algorithm, and the dam surface deformation monitoring result is displayed in real time through the monitoring center. Automatic and real-time monitoring of dam surface deformation is realized, the investment of manpower and material resources is reduced, and the technical difficulty and cost of dam surface deformation monitoring are reduced.

Description

technical field [0001] The present application relates to the technical field of monitoring, in particular to a system and method for monitoring the deformation of a dam surface. Background technique [0002] Reservoir dams are an important social public product and a stable and reliable guarantee in economic and social development. They are an indispensable and important foundation for flood and drought disaster prevention, optimal allocation of water resources, energy supply and regulation, agricultural irrigation, and maintenance of water ecology and water environment. facility. Since the founding of the People's Republic of China, my country has built a total of 98,000 reservoir dams, most of which were built in the 1960s and 1970s. According to statistics, from 1954 to 2006, 3,496 reservoirs of various types in the country collapsed, including 3,370 small reservoirs, accounting for more than 96.4% of the total number of dam collapses. Every small reservoir needs to wi...
