Radio Telemetry, SCADA, and Wireless Telemetry Systems
Radio telemetry enables long-range data retrieval using compact RF devices. SCADA—short for Supervisory Control And Data Acquisition—is a type of industrial control system that uses computers to monitor and manage complex processes across public and private sectors, including manufacturing, utilities, oil and gas, and more.
A Brief History of SCADA
The evolution of SCADA systems reflects broader advances in computing, networking, and automation. Here’s a brief timeline:
- 1960s: SCADA emerged with early centralized systems using mainframe computers to monitor pipelines and electric grids.
- 1970s: Development of minicomputers made SCADA more accessible; proprietary systems dominated.
- 1980s: The rise of distributed systems introduced remote terminal units (RTUs) and programmable logic controllers (PLCs).
- 1990s: Open protocols like Modbus and DNP3 improved interoperability. Human-Machine Interfaces (HMIs) became standard.
- 2000s: SCADA systems began transitioning to IP-based networks. SCADA over cellular and broadband gained popularity.
- 2010s–Present: SCADA now integrates with cloud platforms, IoT devices, and AI-based analytics for predictive maintenance and cyber-secure operations.
SCADA and Telemetry Applications
These systems are crucial in sectors like water treatment, electrical grids, manufacturing automation, and environmental monitoring. PSI supports a variety of telemetry and SCADA hardware, including Motorola MOTOTRBO-based solutions and networked radio infrastructure tailored for rugged field use.
