IoT-Enabled Current Monitoring: Key Technologies & Architecture
The integration of OFLS Rogowski Coils with IoT involves a three-layer architecture:
Perception Layer (Data Acquisition)
The OFLS Rogowski Coil measures dynamic AC currents (especially in high-frequency and fast-changing environments, such as EV charging stations, renewable energy inverters, and industrial machinery).
Signal conditioning (integrator circuits & ADCs) converts the coil’s output into a digital signal for transmission.
Network Layer (Data Transmission)
Wireless protocols (Wi-Fi, LoRa, NB-IoT, 4G/5G) enable real-time data transfer to cloud platforms or edge devices.
Industrial IoT (IIoT) networks ensure low-latency, high-reliability communication for critical applications like power grid monitoring.
Application Layer (Data Analysis & Control)
Cloud-based platforms (AWS IoT, Azure IoT, Tencent Cloud IoT Explorer) store and analyze current data, applying AI/ML algorithms for anomaly detection, load forecasting, and fault prediction.
Remote dashboards allow operators to monitor current trends, receive alerts, and automate responses (e.g., load shedding, circuit breaker control).
