Refineries operate as complex industrial ecosystems, demanding continuous, precise, and reliable monitoring to ensure safety and efficiency. The Distributed Control System (DCS) acts as the central hub, orchestrating thousands of signals from sensors, controllers, and actuators. ARM-based Single Board Computers (SBCs) offer a cost-effective, energy-efficient, and scalable solution for enhancing real-time monitoring and control within refinery DCS architectures.
ARM SBCs interface with sensors to monitor critical parameters such as temperature, pressure, flow, vibration, and gas concentration.
Support for analog/digital I/O, Modbus, CAN, and OPC-UA ensures seamless integration with both legacy and modern field devices.
Perform local data filtering, signal conditioning, and threshold-based alarms to reduce data load on the central DCS.
Enable real-time edge analytics to detect anomalies, such as temperature spikes or pressure drops, for rapid response.
Transmit data securely via Ethernet, Wi-Fi, or 4G/LTE using built-in encryption protocols (TLS/SSL).
Ensure reliable integration with refinery DCS servers and cloud-based monitoring platforms.
Operate on low power with support for UPS or solar backup, ensuring continuous operation during power disruptions.
Deploy multiple SBCs in parallel to provide redundancy, enhancing overall refinery safety.
Host predictive maintenance algorithms for critical equipment like pumps, compressors, and heat exchangers.
Support AI-based anomaly detection to prevent unplanned shutdowns.
Enable real-time dashboard visualization for operators through embedded HMI software.
