The IRIS-Bus Concept for Seismic Instrumentation

This document outlines the need for standardized interconnection and form factors for seismic instrumentation to facilitate efficient configuration, deployment, and servicing of large arrays of seismic stations. It emphasizes collaboration between IRIS and instrumentation vendors to establish joint standards related to connectors, modules, and enclosures. The paper highlights key components, such as cables, sensors, data loggers, GPS antennas, power controllers, and batteries, with a focus on ensuring compatibility, reliability, and ease of use in the field, as demonstrated in the High Lava Plains Experiment.

  6. How do we get from here to there?

  7. Community/Vendor Joint Standards • Connectors: type, pin-outs, signal levels and protocols • Modules: size, shape, connector locations, locking mechanisms • Enclosures: size, shape, material, connectors, accessories commons.wikimedia.org

  8. Conclusion To get to the point where we can efficiently configure, deploy, and service large arrays of seismic stations, we need to develop standards for interconnection and form factor of seismic instrumentation. Those standards should be jointly developed between IRIS and the instrumentation vendors.
