Seismic Instrumentaions of Building Sensor for Seismic Monitoring
of Building High-rise Building Earthquake Sensor for Structural
Health Monitoring
The robust structural health monitoring system is a sophisticated
solution designed for comprehensive data collection, continuous
monitoring, in-depth data analysis, and real-time intelligent early
warning. This cutting-edge system ensures uninterrupted 24/7
automated intelligent monitoring and offers a diverse range of
advanced data analysis functionalities, including specialized
seismic data analysis and precise structural vibration analysis.
Main Components
- GD-2000A accelerograph: Another essential component that
contributes to the system's functionality.
- Online monitoring software or remote cloud platform monitoring
software: This software is used for monitoring and analysis. The
specific software depends on the on-site network transmission
method.
- Optional accessories: These include SMS alarm modules, data remote
transmission modules, switches, and other supporting accessories,
forming a local or remote data transmission network.
- Power supply options: In case of unstable on-site power supply
conditions, there are alternatives such as a solar power supply
system or an independent UPS power supply system.

Feature
- Multi -strong seizure, multi -channel -level, innovative
synchronization mechanism;
- Multi -testing point synchronous sampling, synchronous accuracy
<2us;
- Monitoring software waveform data is simple and easy to use;
- Software has data analysis function, which can realize data
monitoring, analysis, transmission, and early warning functions;
- Remote real -time reception, analysis, display and storage of
multiple album data;
- With the trigger function of the earthquake incident, the system
trigger the algorithm based on the unique earthquake incident, and
the trigger of the judgment as an earthquake event will be recorded
and saved by the original data of the incident.
- With earthquake incident record query and historical data query
function
