AI Technical Summary

Technical Problem

Flow-based metering systems in seismic areas face challenges in detecting seismic activity and promptly reporting resource flow rate changes, which can lead to damage in distribution lines, such as gas lines, resulting in potential fires or explosions, and existing systems do not efficiently adjust their reporting rates to respond to such events.

Method used

The metering device measures seismic activity and flow rates, adjusting its reporting rate from a default to an event or exception rate when seismic activity exceeds a threshold, allowing for more frequent communication with external devices during seismic events, enabling quicker response to potential line damage.

Benefits of technology

This solution enables utilities to rapidly detect seismic events and potential damage to distribution networks, facilitating timely actions like disconnecting users or sending engineers, while maintaining low power consumption and reducing the risk of accidents.

Abstract

Certain aspects and features include techniques for reporting resource flow at a metering device. In an example, a metering device measures resource flow by measuring a pressure or a flow rate. The metering device sets a reporting rate to a default reporting rate. The metering device transmits communications indicating the measured resource flow to an external device at the reporting rate. The metering device detects seismic activity at the metering device. The metering device determines that the seismic activity exceeds a seismic threshold. The metering device, in response to determining that the seismic activity exceeds the seismic threshold, adjusts the reporting rate to an event reporting rate, and starts an event time period. The metering device, transmits communications indicating the measured resource flow to the external device at the event reporting rate during the event time period.
