tunnel lighting environment monitoring and equipment operating status variables

This dataset comprehensively captures the operational dynamics of tunnel lighting systems through continuous monitoring of 12 key parameters—including equipment status (illuminance levels, contactor waterproof state), environmental conditions (temperature, humidity, voltage fluctuations), and operational profiles (daily runtime)—across a 15.2-km highway tunnel network over 46 months (2019–2022). Data was acquired at 5-second resolution for equipment and 1-minute resolution for environment via industrial-grade sensors (illuminance meters, T/H sensors, smart meters) deployed at 100-m intervals across 152 spatial units, with vertical stratification at ceiling (5.2m), mid-air (2.5m), and road-level (0m).

Raw measurements underwent edge preprocessing (3σ anomaly filtering, wavelet-based smoothing), spatiotemporal alignment, and feature engineering before storage in InfluxDB, yielding 130 million structured records optimized for analyzing thermal-electrical coupling, fault prediction, and energy efficiency under industry-compliant (JTJ 026.1-1999) conditions.
