公路LED可变信息标志是现代交通管理的重要机电设备,是公路沿线单位能耗最大的用电设施之一,2014年8月交通运输部下达了《公路LED可变信息标志能效限定值及能效等级》(计划编号JT2014-25)行业标准制定计划。本文重点研究分析了公路LED可变信息标志的能耗主要影响因素,通过分析比较,提出了公路LED可变信息标志能效表征单位及其定义,为制定公路LED可变信息标志能效限定值、能效等级及其评定方法行业标准奠定基础。
Highway LED variable information sign is an important modern traffic management, mechanical and electrical equipment, is one of the most energy-consuming facilities along the highway unit, in August 2014 the Ministry of Transport issued a “road LED variable information signs energy efficiency limit value and energy efficiency Grade ”(plan number JT2014-25) industry standard setting plan. This paper focuses on the analysis of road LED variable information signs of energy consumption of the main impact factors, through analysis and comparison, proposed highway LED variable information sign energy efficiency performance unit and its definition, in order to develop highway LED variable information sign energy efficiency limit value, energy efficiency Grade and its evaluation method of laying the foundation for industry standards.
