Universal Data Acquisition – Integrated System with Analytics on the Edge

UniDAQ is a universal data acquisition device that acquires sensor and field equipment data from a variety of data sources on any site. It simplifies data acquisition by providing one integrated system. Data is acquired using standard industrial methods and protocols, analogue, digital, Modbus and OPC among others. It translates and presents readings and selected metadata via an embedded OPC UA server. This provides easy access for 3rd party applications and devices with a standardized, secure, widely accepted OPC protocol.

Powerful Edge Analytics for more efficient decision-making

UniDAQ is capable of oil industry Edge Analytics, performing complex calculations and analytics at the data acquisition level in real-time. It presents calculated variables as additional data streams for immediate viewing and informed decision-making. This allows for fast predictive analysis, identification of potential problems before they occur, and optimization of the operational process directly on-site.

Scalability Designed to fit any Configuration

The system offers a scalable, modular solution that provides acquisition and analytics from small remote monitoring devices of a small subset of sensors, to full rig set-ups with 100+ data streams. This enables standardization across asset fleets for data analysis, remote configuration and predictive maintenance.

Features and Benefits

  • High speed data acquisition
  • Standard protocols – analogue, digital, Modbus, OPC and more
  • Easy access for 3rd party applications
  • Powerful Edge Analytics for more efficient decision-making
  • Fast, predictive analysis to identify problems as and even before they occur
  • Scalability designed to fit any configuration

As well as the advanced UniDAQ device level security features, the UniDAQ system can be extended to securely bridge a trusted corporate network and an untrusted data acquisition network by connecting a UniDAQ unit in each of the two networks using PetroDAQ’s proprietary UniDAQ DAQ-Guard Link. The DAQ-Guard Link facilitates the flow of ‘permitted’ data between the two networks but ensures they are completely isolated by a protocol “air gap”, eliminating the possibility of any transfer of malware between the network segments.

The UniDAQ DAQ-Guard Link consists of a single device containing two separate network link boards (one for each of the two networks to be linked) connected by an internal fibre-optic cable. Each link board within the DAQ-Guard Link is designed to only connect to a single UniDAQ unit using an authentication process based the UniDAQ unit’s Intel Platform Trusted Technology unique key.

When deployed, the rig side (untrusted) UniDAQ is connected to one side of the DAQ-Guard Link with the corporate network side (trusted) UniDAQ connected to the other. The rig side UniDAQ has full UniDAQ capabilities including the aggregation of data from multiple sources and service contractors, high speed calculations, analytics, archiving and visualization.

The rig side UniDAQ outputs aggregated and calculated data into a proprietary format which is streamed to the connected DAQ-Guard Link. Any data packets received by the Link not complying to the proprietary format are automatically rejected removing any potential embedded malware. TCP header and routing information is stripped out by the Link further eliminating any packet-based malware. Only the remaining data payload is serialized across the fibre-optic link using a non-TCP based protocol (‘air-gap’). On the opposite side of the link, the stream is de-serialized and routed to the connected UniDAQ for export on to the corporate network using any of the standard UniDAQ export modules including WITSML, ETP and OPC UA. The UniDAQ DAQ-Guard Link additionally offers bi-directional capabilities supporting the secure transfer of supporting data, calculations, configuration updates and instructions from a centralized control room to the rig side unit.
