Abstract

A control system for aggregating metadata at hydrocarbon site is shown. The control system includes one or more edge devices. At least one of the one or more edge devices includes a processing circuit configured to receive sensor data from a plurality of sensors and integrate the received sensor data into a set of metadata, the set of metadata including stored operational data of the hydrocarbon site. The processing circuit is configured to aggregate the set of metadata according to one or more criteria, the one or more criteria configured to categorize the received sensor data. The processing circuit is configured to identify one or more connected devices based on the aggregated set of metadata and the one or more criteria and adjust operation of the one or more edge devices based on the aggregated set of metadata.

First claim

What is claimed is:

1 . A control system for aggregating metadata at hydrocarbon site, the control system comprising one or more edge devices, wherein at least one of the one or more edge devices comprises a processing circuit configured to:
receive sensor data from a plurality of sensors, each of the plurality of sensors having a first sensor type, wherein:
a first set of the sensor data from a first sensor of the plurality of sensors has a first format, the first set of the sensor data corresponding to a first measured parameter, and
a second set of the sensor data from a second sensor of the plurality of sensors has a second format, the second set of the sensor data corresponding to the first measured parameter;
integrate the received sensor data into a set of metadata, the set of metadata comprising stored operational data of the hydrocarbon site; aggregate the set of metadata according to one or more criteria, the one or more criteria configured to categorize the received sensor data, wherein aggregating the set of metadata is performed by the one or more edge devices and comprises:
converting the sensor data into a standardized format by converting at least the first set of sensor data and the second set of sensor data from the first format and the second format into the standardized format;
determining a type of data for the sensor data based on the standardized format, such that the metadata is categorized according to the standardized format;
creating at least one of a dictionary or lexicon configured to determine relationships within the set of metadata; and
mapping disparate representations using the at least one of the created dictionary or created lexicon such that a first portion of the metadata is mapped to the first sensor type, the first portion of the metadata corresponding to a first characteristic of the sensor data; and
adjust operation of the one or more edge devices based on the aggregated set of metadata, such that the one or more edge devices are configured to:
receive additional sensor data from an additional sensor, the additional sensor data associated with additional metadata;
automatically inferring a second characteristic of the additional sensor data based on retrieving, from a register of the at least one of the one or more edge devices, a contents of the register that correspond to the second characteristic; and
automatically determine that a sensor type of the additional sensor is the first sensor type based on comparing the additional metadata to the first portion of the metadata and comparing the first characteristic to the second characteristic.

2 . The control system of claim 1 , wherein the processing circuit is further configured to:
identify one or more connected devices based on the aggregated set of metadata and the one or more criteria; and adjust the operation of the one or more edge devices based on the aggregated set of metadata and a set of information received from at least one of the one or more connected devices.

3 . The control system of claim 1 , wherein:
integrated sensor data is a first subset of the metadata and operational data is a second subset of the metadata; and aggregating the set of metadata according to the one or more criteria comprises: determining relationships between the first subset of the metadata and the second subset of the metadata; and mapping at least part of the first subset of the metadata to at least part of the second subset of the metadata.

4 . The control system of claim 3 , wherein the at least one of the created dictionary or created lexicon comprises categories that combine the criteria into one or more of the categories.

5 . The control system of claim 1 , wherein receiving sensor data from the plurality of sensors comprises receiving data from at least one of a field controllers or a hydrocarbon site device.

6 . The control system of claim 1 , wherein aggregating the set of metadata according to the one or more criteria comprises using heuristics and a prior information of register contents to automatically infer one or more characteristics of the set of metadata.

7 . The control system of claim 1 , wherein the processing circuit is further configured to perform an automatic scan to detect one or more connected devices or one or more criteria or a combination of the one or more connected devices and the one or more criteria.

8 . The control system of claim 1 , wherein aggregating the set of metadata according to the one or more criteria comprises using heuristics and a prior information of register contents to automatically infer one or more characteristics of the set of metadata, and wherein the processing circuit is further configured to perform an automatic scan to detect one or more connected devices or one on or more criteria or a combination of the one or more connected devices and the one or more criteria.

9 . A computer readable media for aggregating metadata at hydrocarbon site comprising a processing circuit comprising one or more processors and memory storing instructions that, when executed by the one or more processors, causes the one or more processors to perform operations comprising:
receiving sensor data from a plurality of sensors, each of the plurality of sensors having a first sensor type, wherein: a first set of the sensor data from a first sensor of the plurality of sensors has a first format, the first set of the sensor data corresponding to a first measured parameter, and a second set of the sensor data from a second sensor of the plurality of sensors has a second format, the second set of the sensor data corresponding to the first measured parameter; integrating the received sensor data into a set of metadata, the set of metadata comprising stored operational data of the hydrocarbon site; aggregating the set of metadata according to one or more criteria, the one or more criteria configured to categorize the received sensor data, wherein aggregating the set of metadata is performed by one or more edge devices and comprises:
converting the sensor data into a standardized format by converting at least the first set of sensor data and the second set of sensor data from the first format and the second format into the standardized format;
determining a type of data for the sensor data based on the standardized format, such that the metadata is categorized according to the standardized format;
creating at least one of a dictionary or lexicon configured to determine relationships within the set of metadata;
mapping disparate representations using the at least one of the created dictionary or created lexicon such that a first portion of the metadata is mapped to the first sensor type, the first portion of the metadata corresponding to a first characteristic of the sensor data;
identifying one or more connected devices based on the aggregated set of metadata and the one or more criteria; and adjusting operation of one or more edge devices based on the aggregated set of metadata, such that the one or more edge devices are configured to:
receive additional data from one or more connected devices, the additional data associated with additional metadata;
automatically inferring a second characteristic of the additional data based on retrieving, from a register of the at least one of the one or more edge devices, a contents of the register that correspond to the second characteristic; and
automatically determining that a type of the one or more connected devices is the first sensor type based on comparing the additional metadata to the first portion of the metadata and comparing the first characteristic to the second characteristic.
