摘　　要：路面凝冰严重影响道路的交通运输安全,建立高速公路路面凝冰监测和预警系统,提高道路交通系统应对冰雪天气的反应时效,最大限度地减少由积雪凝冰带来的不利影响,是当前技术条件下的最优策略。文章基于路面凝冰形成环境条件和判别标准研究,选用半导体制冷器设计一种性价比高、可长期服役且精确度较高的道路冰雪智能监测埋入式传感器,提出智能路面凝冰状况传感器的基本设计原则和工作原理,并与路域自动微气象站和预警管理平台组成路面凝冰监测预警管理系统,具备路面状况实时监测、早期预警、实时预报等多项功能,保障冰雪条件下高速公路畅通和行车安全。Road ice has a serious impact on highway traffic and transportation safety.The optimal strategy under current technical conditions is to establish a monitoring and early warning system for road ice,improve the response time of road traffic system to ice and snow weather,and minimize the adverse effects brought by snow ice.Based on the research on the environmental conditions and criteria for the formation of road ice,this paper designs a cost-effective,long-term service,and high precision contact sensor for intelligent monitoring of road ice and snow by using a semiconductor refrigerator.The basic design principles and working principles of the intelligent road ice condition sensor are proposed,and a road ice early warning system with automatic micro-weather station and early warning management platform is formed.It has multiple functions such as real-time monitoring of road conditions,early warning,and real-time forecasting,etc.,to ensure the smooth flow of expressway and driving safety under snow and ice conditions.
