Theta Empowers the Development of Smart Power Plants

As raw material costs continue to rise, traditional thermal power plants are facing increasing financial pressure. Relying solely on production expansion to boost revenue is no longer sufficient to improve profitability. The industry urgently needs technological upgrades and management innovation to accelerate the transformation toward smart power plants. Leveraging emerging technologies such as advanced sensors, the Internet of Things (IoT), and artificial intelligence, smart power plants have become a key solution to improving quality and efficiency while reducing energy consumption and operational costs. As a pioneer in industrial digital transformation, Theta provides power plants with industrial-grade sensing systems specifically engineered for harsh industrial environments. Our solutions offer reliable, comprehensive data support for equipment condition monitoring and fault diagnostics. Key products include vibration-temperature sensors, pressure sensors, temperature sensors, and corrosion sensors — forming the core data acquisition foundation of smart power plants.

With Theta’s monitoring system, power plants gain real-time visibility into the condition of critical equipment, enabling early fault detection, optimized maintenance decision-making, and a data-driven approach to intelligent operations.

01 Sensor System Architecture

To achieve full-scale, high-efficiency equipment monitoring and data collection, Theta has developed a hybrid sensor architecture that integrates wireless and wired sensors:

• Wireless sensors are ideal for widely distributed or hard-to-wire locations
• Wired sensors meet the needs of latency-sensitive monitoring tasks

Both sensor types are connected through a unified gateway for centralized data collection. Wireless nodes use Theta’s proprietary low-power network to transmit data to the gateway, while wired nodes connect via RS485. The gateway supports Ethernet or 4G/5G connections to transmit data to local servers or cloud platforms.

02 Key Product Advantages

High-Performance Sensors

Theta’s sensors feature low noise, high precision, ultra-low power consumption, and explosion-proof ruggedization, making them ideal for high-temperature, high-pressure, and high-vibration environments.

For example, our wireless vibration-temperature sensors are equipped with triaxial accelerometers and edge computing capabilities. They extract 24-dimensional vibration features on-site, enabling real-time identification of mechanical faults such as imbalance, looseness, bearing wear, gear defects, and more.

All data is wirelessly transmitted to the monitoring platform, where users can remotely visualize waveforms, features, and trends — enabling early fault detection and reducing unplanned downtime.

Multi-Protocol Smart Gateway

The GU series gateway is the system’s central hub, supporting simultaneous access to both wireless and wired nodes. It handles protocol conversion and supports MQTT, Modbus, HTTP, and other protocols. The gateway includes Ethernet, 4G, RS485, and CAN interfaces, allowing seamless integration with SCADA systems or cloud platforms. With its open architecture, the gateway supports third-party system integration and secondary development, making it adaptable to a wide range of smart power plant scenarios.

04 Intelligent Diagnostics & Predictive Maintenance

Beyond real-time monitoring, Theta’s system enables advanced fault diagnostics and predictive analytics based on long-term operational data. This empowers power plants to implement condition-based maintenance strategies, proactively address potential failures, and improve equipment availability and operational efficiency.

Conclusion

Smart power plant construction is a crucial step toward high-quality development in the energy sector. With industry-leading sensing and data technologies, Theta supports power generation enterprises in building robust digital monitoring systems that enhance safety, reliability, and cost-effectiveness — injecting lasting intelligence into the evolution of the energy industry.
