Lufft NIRS21 遙感式路面狀況傳感器 產品介紹
德國Lufft公司推出的NIRS21是一款基于近紅外光譜分析技術的非接觸式路面狀態監測設備。該傳感器通過遙感探測方式，可在5米范圍內實時采集道路表面狀態數據，為交通管理、道路維護提供關鍵決策支持。
技術原理與功能特點
設備采用多光譜傳感技術，通過分析不同波長近紅外光的反射特性，精確識別路面干爽、潮濕、積雪、結冰等多種狀態。內置算法可同步計算水膜厚度（0-4mm）、冰層厚度（0-2mm）及積雪深度（0-10cm）等參數，測量精度達到毫米級。獨特的抗振動設計使其適用于移動測量場景，支持車載安裝進行道路巡檢作業。
全天候監測能力
NIRS21搭載環境光補償系統，在強日光、夜間等復雜光照條件下仍能保持穩定性能。工作溫度覆蓋-40℃至+60℃范圍，防護等級達到IP68，可適應雨雪、沙塵等惡劣天氣環境。設備內置自清潔結構，有效避免飛濺污染物對測量結果的影響。
智能化數據應用
傳感器支持RS485、CAN總線等多種工業通信協議，輸出頻率最高可達10Hz。配套軟件平臺提供數據可視化界面，支持歷史趨勢分析、異常狀態預警等功能。通過對接交通管理系統，可動態調整限速提示、融雪劑噴灑等道路養護策略。
安裝與維護優勢
模塊化設計使設備支持立柱側裝、龍門架懸吊等多種安裝方式，15分鐘即可完成部署。采用低功耗設計（典型功耗<3W），支持太陽能供電系統，適用于無市電供應的偏遠路段。Lufft提供兩年質保服務，設備平均無故障工作時間超過50,000小時。
該產品已成功應用于全球30多個國家和地區的智能公路、機場跑道等場景，其可靠性和環境適應性得到廣泛驗證。通過持續的技術迭代，NIRS21正為道路安全監測領域提供創新的解決方案。
Lufft NIRS21 Road Surface Sensor Product Introduction
The NIRS21 from German manufacturer Lufft is a non-contact road condition monitoring device utilizing near-infrared spectroscopy. This remote sensing instrument captures real-time surface status data within a 5-meter range, delivering essential information for traffic management and infrastructure maintenance.
Technical Features
Equipped with multispectral sensing technology, the device analyzes reflected NIR wavelengths to accurately identify dry, wet, icy, or snowy road conditions. Its advanced algorithms calculate water film (0-4mm), ice thickness (0-2mm), and snow depth (0-10cm) with millimeter-level precision. The vibration-resistant design enables reliable operation in mobile measurement applications.
All-Weather Performance
Featuring ambient light compensation, the sensor maintains stable operation under intense sunlight or nighttime conditions. With an operational range of -40℃ to +60℃ and IP68 protection rating, it withstands heavy rain, snowstorms, and dust exposure. The self-cleaning mechanism effectively prevents measurement interference from road contaminants.
Smart Data Integration
Supporting RS485 and CAN bus protocols, the device offers data transmission up to 10Hz. The companion software provides visualization tools for trend analysis and condition alerts. Integration with traffic management systems enables dynamic control of speed limits and de-icing operations.
Deployment Advantages
Modular design allows flexible installation on poles or gantries, with deployment completed within 15 minutes. Low power consumption (<3W) enables solar-powered operation in remote areas. Backed by a two-year warranty, the device demonstrates over 50,000 hours MTBF in field applications.
This solution has been implemented in smart highways and airport runways across 30+ countries, proving its reliability in diverse environments. Through continuous innovation, NIRS21 sets new benchmarks for road safety monitoring technology.
