Description

A power tunnel monitoring data acquisition device

technical field

The utility model relates to an electric tunnel monitoring related technology, in particular to an electric tunnel monitoring data acquisition device.

Background technique

Since the 1990s, with the implementation of large-scale engineering projects such as long-span railway and highway bridges, large hydropower stations, the International Space Station program, and the Mars unmanned exploration program, the health diagnosis of large-scale structural systems related to dynamic characteristics has rapidly become an international issue. It is a hot spot in the academic and engineering circles, and has many application examples in the fields of bridges and high-rise buildings: Robert et al. in the United States carried out monitoring of light rail overhead cement structures, and carried out online monitoring of 8 rail sections under different weather conditions and structural health diagnosis and analysis; Germany has installed a health monitoring system in the newly built Lehrter Bahnhof (Berlin) building in Berlin; however, in terms of large tunnels, there are few cases where the health monitoring system is used to monitor and manage structures.

Currently, domestic and foreign research on tunnel monitoring systems and successful cases of engineering information integration mainly include the subway information integrated management system in New York, the United States, and the urban subway management and operation system in Tokyo, Japan. However, these systems are mainly from the daily operation and management of the subway Maintenance starts, focusing on the management and maintenance of train groups and equipment, as well as emergency dispatch and crowd evacuation in emergency situations, and less involved in the diagnosis and treatment of structural diseases and the monitoring of engineering mechanics.
