Abstract

An industrial sensing network includes a plurality of sensors, each sensor being configured to monitor at least one condition associated with equipment deployed in an industrial complex. The sensing network also includes at least one fixed aggregator configured to gather data collected by one or more of the plurality of sensors and relay the data to a user. The aggregator includes a local communication arrangement configured for communication with other devices deployed within the complex, an external communication arrangement configured for communication with devices external to the complex, a self-contained power source configured to power the aggregator, a processor programmed to at least partially process data, and a storage arrangement configured to at least temporarily store data. At least one sensor is configured to at least partially process sensor measurements into data prior to transmission to the aggregator.

Claims

1. An industrial sensing network, comprising:

a plurality of sensors, each sensor being configured to monitor at least one condition associated with equipment deployed in an industrial complex; and

at least one fixed aggregator configured to gather data collected by one or more of the plurality of sensors and relay the data to a user, the aggregator including;

a local communication arrangement configured for communication with other devices deployed within the complex;

an external communication arrangement configured for communication with devices external to the complex;

a self-contained power source configured to power the aggregator;

a processor programmed to at least partially process data; and

a storage arrangement configured to at least temporarily store data;

wherein at least one sensor is configured to at least partially process sensor measurements into data prior to transmission to the aggregator.

2. The industrial sensing network of claim 1, wherein the fixed aggregator is configured to poll the one or more sensors to cause the sensors to transmit data.
