I. Requirements Analysis

In seismic monitoring and research, high-precision, wide-band seismic data acquisition is crucial for understanding seismic activity patterns, assessing earthquake risks, and developing early warning systems. Traditional seismometers often suffer from issues such as bulky size, complex installation, and poor portability, making them ill-suited for rapid field deployment and flexible monitoring. Therefore, we have developed this portable, integrated wideband seismometer to address these challenges, providing seismologists, research institutions, and emergency management agencies with an efficient, portable, and reliable monitoring tool.

II. Product Features

1. Integrated design featuring a combined orthogonal triaxial broadband seismometer and seismic data acquisition recorder.

2. Built-in automatic zero-position monitoring, electromechanical unlocking swing, and electromechanical zero adjustment, enabling remote programmable unlocking, locking swing, and zero-position adjustment.

3. The dynamic range of the entire unit exceeds 142 dB; it maintains low self-noise within the frequency band.

4. Cross-axis suppression greater than 62 dB; sensor three-axis orthogonal error less than ±1°.

5. Data acquisition with over 27 effective bits, with zero input noise ≤2μV on the main acquisition channel (+20V range).

6. Supports fast, low-latency data streams with 0.2-second packing intervals, supports multiple connections, and supports FTP data downloads.

III. Application Scenarios

1. Earthquake Monitoring Network Deployment: As a vital component of the earthquake monitoring network, it is rapidly deployed in critical regions to enhance monitoring density and timeliness.

2. Earthquake Early Warning System: Real-time collection of seismic data provides critical inputs for the earthquake early warning system, reducing warning time.

3. Research and Education: Used for seismological research and teaching experiments, providing high-quality seismic waveform data.

4. Emergency Response: Rapidly deploy to disaster areas following an earthquake to provide data support for damage assessment and rescue decision-making.
