Report in Brief
Wide-band seismic is one of the main methods to detect and study the deep part of the Earth. A 32-bit wide-band seismic recorder with a 32-bit SAR-type ADC as the main component is designed. Compared with the popular 24-bit seismometers, the wide-band seismometer with 32-bit A/D has higher resolution and larger dynamic range, which can sense the tiny vibrations from seismic sensors and provide more detailed data for scientific research and deep detection. In addition to being able to store seismic data locally, the instrument can also be connected to a cloud server via various methods such as wired Ethernet, Bluetooth, WIFI wireless communication capabilities and 3G/4G mobile communication networks to access Ethernet for real-time monitoring of the instrument's operating status or remote recovery of data.
