As a three-phase smart meter manufacturer, we leverage our years of technical expertise and industry standards to introduce a new-generation three-phase smart meter integrated with cutting-edge IoT capabilities.
1. Modular Hardware Architecture for Real-Time Data Acquisition
Measurement Module:
Equipped with high-precision metering chips and temperature-compensated real-time clocks to capture three-phase current/voltage, active/reactive power (including harmonics), and power factor.
Management Module:
Runs an embedded RTOS (Real-Time Operating System) for parallel processing of data validation, compression, and secure storage via ESAM encryption.
Expandable IoT Modules:
Supports NB-IoT, 4G, LoRa, and 6 communication protocols to adapt to diverse industrial environments.
2. Dual-Channel IoT Communication for Minute-Level Updates
Primary Channel (NB-IoT): Transmits data every 15 seconds with 5G-level network slicing for prioritized industrial traffic.
Backup Channel (470MHz LPWAN): Activates automatically during cellular outages, guaranteeing data delivery within 3 minutes.
Edge AI Processing: On-device anomaly detection (e.g., power surges, leakage) filters 30% of redundant data before transmission.
3. Cloud Platform for Energy Analytics
Real-Time Dashboard: Energy usage via dynamic load curves and heatmaps, drillable by device, production line, or workshop.
AI-Powered Diagnostics: Identifies energy-intensive equipment (e.g., compressors, cooling towers) and recommends optimizations like load balancing or time-of-use adjustments.
Carbon Tracking: Integrates regional grid carbon intensity data to generate ISO 14064-compliant carbon reports for the target date.
4. User Interaction & Proactive Alerts
Multi-Access Interfaces: Web/MES integration and WeChat Mini-Programs allow real-time monitoring , energy data and threshold alerts (e.g., daily budget overruns).
Automated Control: Triggers PLC-driven shutdowns for non-operational equipment wasting power, cutting energy loss by up to 18%.
5. Compliance & Security
Certifications: Complies with IEC 62052-11:2024 and IR46 legal metrology standards to ensure audit-ready data validity.
End-to-End Security: Implements SM4 encryption and anti-tamper mechanisms aligned with GB/T 22239-202X IoT security guidelines.
