Problems solved by technology

[0006] Most of the strong motion monitoring of existing dams uses general-purpose strong motion instruments. These strong motion instruments can realize the collection of strong motion responses of dams, but there is no system software and method for rapid analysis and judgment on the safety of strong motion of dams , unable to quickly provide technical support for disaster reduction after the dam earthquake

Embodiment Construction

[0027] The present invention-a strong vibration safety monitoring and early warning system for dams based on Internet remote management is mainly applicable to hydraulic structures such as dams, and monitors and analyzes the strong vibration responses of hydraulic structures such as dams, and its Post-earthquake safety assessment and early warning. According to the requirements of the code, the measuring points are arranged at the critical and sensitive parts of the hydraulic building structure, and the one-way or three-way acceleration vibration pickups are arranged on these measuring points. The vibration pickup signal is transmitted through the shielded cable to the multi-channel dynamic data acquisition instrument after being marked according to the channel allocation. The acquisition instrument is connected to the acquisition server to be powered on and started.

Abstract

The invention discloses a dam strong vibration safety monitoring and pre-warning system based on Internet remote management. The system comprises dam strong vibration monitoring equipment, an acquisition server for receiving dam strong vibration monitoring data and a remote management server. The dam strong vibration monitoring equipment comprises a plurality of vibration pickups and a multichannel dynamic data acquisition instrument. Dam strong vibration monitoring system software (including dam strong vibration acquisition software, dam strong vibration analysis software and dam strong vibration safety evaluation software), equipment end management system software and a software interface of a dam safety monitoring system are run on the acquisition server. Remote management system software is run on the remote management server. According to the dam strong vibration safety monitoring and the pre-warning system based on the Internet remote management, fast analysis, evaluation and alarm are conducted on dam post-seismic safety through a dam strong vibration response, support for dam earthquake resistance and disaster reduction is provided, and remote management, and unattended operation and database management are achieved.

Description

technical field [0001] The invention relates to a strong vibration monitoring technology of a dam. In particular, it relates to a dam strong vibration system capable of remote management, rapid analysis of the strong vibration response of the dam, evaluation and early warning of the safety of the dam after a strong earthquake, and the ability to quickly provide technical support for disaster reduction after the dam earthquake Safety monitoring system. Background technique [0002] The dam strong vibration monitoring system is a dynamic monitoring system that monitors the seismic / vibration response of each position of the dam in real time through the shock pickups (acceleration sensors) arranged at key parts of the dam. When vibrating, the strong vibration response of the dam can be recorded. [0003] The seismic acceleration response of the dam can be used to verify and review the seismic design of the dam structure, improve people's understanding of the nonlinear response...
