DAS技术在公路智能监测领域的应用
Application of DAS technology in intelligent highway monitoring
摘要
Abstract
To address the limitations of traditional point sensors in long-distance continuous monitoring and internal hidden de-fect identification on highways,this paper elaborates on the sensing principles,system architecture,optical fiber deployment schemes,as well as signal processing and parameter inversion techniques of distributed acoustic sensing(DAS).The applica-tions of DAS in pavement defect detection,slope warning,and perimeter security are summarized.Furthermore,a non-excavation full-link pavement monitoring system was implemented to verify vehicle type identification and all-day quantitative traffic flow monitoring.The results demonstrate that the system can effectively achieve integrated monitoring of traffic opera-tional status and structural health,providing all-weather data on vehicle types and quantified traffic flow,thereby validating the feasibility and application value of DAS technology in deep perception of the entire structure of smart highways.关键词
