Industrial Boundary Noise Monitoring System
System Overview
The Industrial Boundary Noise Online Monitoring System integrates IoT technology for real-time noise monitoring, compliance management, over-limit alerts, and source traceability. It is ideal for industrial plants, industrial parks, and noise-sensitive areas, supporting environmental acceptance, emission permits, and daily regulatory supervision.
Key Features
- Intelligent End-to-End Monitoring: Designed for industrial boundaries, the system enables 24/7 noise monitoring with compliance assessment, over-limit alerts, evidence recording, and closed-loop management from monitoring to verification.
- Remote Self-Diagnostics & Event Recording: Supports over-limit audio recording, remote playback, self-diagnostics, and automatic data recovery after communication interruption, ensuring reliable monitoring.
- Multi-Parameter Monitoring Expansion: Expandable with meteorological parameters, GPS, over-limit video capture, and noise source localization for comprehensive monitoring.
