SEISMIC NOISE ACQUISITION DEVICE, WIRELESS TELEMETRY SYSTEM, AND DATA QUALITY MONITORING METHOD

摘要

A seismic noise acquisition device (20), a system, and a data quality monitoring method, belonging to the technical field of electronic seismographs. The seismic noise acquisition device (20) is connected to an output end of a vibration sensor (10), and comprises a data acquisition module (1), a data processing module (2), a network port forwarding module (3), a GPS module (4), and a data storage module (5). The output end of the vibration sensor (10) is connected to the data acquisition module (1). The data acquisition module (1) and the GPS module (4) are both connected to the data processing module (2). The data processing module (2), the network port forwarding module (3), and the data storage module (5) are all connected to an embedded Linux system platform (6). GPS satellite standard time signals are used to correct internal clock signals automatically and in real time, thereby ensuring that respective seismic noise acquisition devices can acquire data in a synchronous manner during long-term data acquisition.
