Design of Expressway Safety Early Warning System Based on Internet of Things

摘要

Aiming at the current situation of frequent accidents and slow rescue in the safety management of expressways in China,this paper integrates electronic,computer and Internet of Things technologies to form a self-organizing network through the routing nodes laid on the expressways,and constitutes a expressway safety warning system.At the same time,the mobile App,Web and PC monitoring platforms were developed and aggregated into the expressway traffic management center to realize real-time transmission and release of cross-platform alarm information.The test results show that the system can effectively reduce the incidence of accidents,especially secondary accidents,shorten the rescue time and improve the smooth flow rate of roads.
