Design of Icy Dectection System for Highway Pavement Based on ZigBee

摘要:

针对高速公路上结冰状况仅靠驾驶员观察易导致事故的现状,根据结冰温度和冰的导电性,并结合光在冰层中的传播特性,提出一种利用ZigBee技术的新型的高速公路路面结冰信息检测系统;该系统以楔形光纤作为光的传播媒介,通过采集光纤内光强的变化,结合温度和阻值的大小来融合出高速公路上冰的冰厚和冰型;介绍温度、阻值和光强等采集模块的设计原理,及实验测试环境的实现;经过验证,该系统可有效检测出路面的冰厚和冰型。

Abstract:

Aimed at relying on the observation of drivers easily lead to accidents on the highway, according to the freezing temperature and conductivity of ice, combined with the optical transmission characteristics in the ice, this paper presented a new innovative system which is icy dectection system for highway pavement based on ZigBee. This system can get the ice thickness and ice type by changing the collection fiber intensity, with temperature and resistance. The design principle of the resistance temperature and light intensity acquisition module is introduced in detail, the experimental test environment is introduced. After verification, the system can effectively detect the ice thickness and ice type. 
