The invention provides an expressway agglomerate fog early warning method and system based on an LED information screen, and the method comprises the steps: taking an LED information screen intelligent terminal distributed at the side of an expressway as an edge calculation node, and carrying out the interaction with a remote meteorological analysis system deployed at a cloud platform; acquiring meteorological data in a local area through an LED information screen intelligent terminal, performing preliminary analysis, and uploading a preliminary analysis result to a remote meteorological analysis system; and enabling the remote meteorological analysis system to further analyze the preliminary analysis result to obtain meteorological distribution characteristics of all parts of the expressway, generate corresponding published content, and issue the published content to the LED information screen intelligent terminal for publishing. According to the invention, rapid analysis and early warning of the highway agglomerate fog condition can be achieved.

    本发明提出一种基于LED信息屏的高速公路团雾预警方法及系统,以布设在高速公路路侧布设LED信息屏智能终端作为边缘计算节点,与部署在云平台的远程气象分析系统交互;通过LED信息屏智能终端采集所在局部区域内的气象数据并进行初步分析,然后将初步分析结果上传至远程气象分析系统;远程气象分析系统通过对初步分析结果进行进一步分析,得到高速公路各处的气象分布特征,进而生成对应的发布内容,并将发布内容下发至LED信息屏智能终端发布。本发明可实现高速公路团雾情况的快速分析和预警。
