Abstract

This invention discloses a rain sensing device and its sensing system for autonomous vehicles based on the Internet of Things (IoT), relating to the field of autonomous vehicle technology. The invention includes a vehicle body and a mounting base. The mounting base is fixed to the upper side of the vehicle body, and a mounting column is installed on the upper side of the mounting base. Both the mounting column and the mounting base have circular grooves inside, which communicate with the interior of the vehicle body. This invention uses an electric heating network to melt snow and ice falling on it, allowing the rain and snow sensor to quickly detect snowfall and rapidly transmit the information to the onboard computer unit. This improves the autonomous vehicle's snow perception capability and reaction speed. Furthermore, a pressurization mechanism utilizes the vehicle's heating system to melt the frozen ice on the rain and snow sensor, resulting in energy conservation and environmental protection. A fan can provide an air source when the vehicle's heating is off.
