|
Abstract:
高速公路下穿涵洞积水经常带来交通堵塞，人员伤亡和财产损失等问题，为了解决此类问题，设计出一款基于双波长数据融合的高速公路涵洞积水便携式无线传感器。该传感器由锂电池、毫米波雷达、激光雷达、4G通讯模块和控制电路等部分组成，通过算法设计实现毫米波雷达数据和激光雷达数据的双波长融合。该传感器在杭州绕城西复线S43湖州段内5处下穿涵洞及杭宁高速2处涵洞完成了安装布设，实测传感精度优于± 3 mm。本文设计实现的基于双波长数据融合的便携式无线传感器，可应用于高速公路涵洞积水监测，具有推广应用价值。
Accumulation of water in highway culverts often leads to traffic congestion, casualties, and property damage. To address these issues, a portable wireless sensor for highway culvert water accumulation based on dual-wavelength data fusion has been designed. The sensor mainly consists of a lithium battery, millimeter-wave radar, lidar, 4G communication module, and control circuit. It achieves dual-wavelength fusion of millimeter-wave radar data and lidar data through algorithm design. The sensor has been installed in five underpasses along the Hangzhou Western Expressway S43 Huzhou section, with a measured sensing distance of up to 10 meters and a sensing accuracy better than 3mm. The portable wireless sensor designed and implemented in this paper, based on dual-wavelength data fusion, can be applied to the monitoring of water accumulation in highway culverts and has the value of promotion and application.
