Description

technical field [0001] The invention belongs to the field of dam safety monitoring, in particular to an arch dam surface deformation monitoring system based on the fusion of GNSS and measuring robots. Background technique [0002] At present, the surface deformation monitoring technology of arch dams is mainly based on manual manipulation and observation instruments. This type of monitoring technology uses laser vertical method, front intersection method, line of sight method and other observation methods, and is measured in the form of manual measurement. Accuracy is high but the frequency is low, most of them can only reach about once a month, and are greatly affected by the technical level of personnel and the measurement environment. With the continuous development of various new monitoring methods, automatic monitoring equipment has been developed and applied in the field of arch dam surface deformation monitoring due to its complete automation of operation and observat...

Problems solved by technology

However, the measurement robot also has the problem of high visibility of the measurement environment, and requires all measurement points to be unobstructed

Combined with the operating characteristics of arch dams, real-time safety monitoring is particularly important to ensure the safe operation of dams under extreme weather conditions such as typhoons and heavy rains. However, it is precisely difficult for measuring robots to achieve accurate monitoring in such environments.
