Intelligent wireless alarm device for vehicle wading
In order to resolve the problem that vehicles wading in deep water and parking immersion are vulnerable to damage in rainstorm,intelligent vehicle anti-flooding alarm device based on NB-IoT communication technology is designed.The device uses ultrasonic sensors to measure the depth of the vehicle's wading,predicts the rising speed of the water level,and dynamically adjusts the measurement interval to reduce power consumption.At the same time,the vehicle switch detection circuit is designed to judge the driving and parking state of the vehicle.When the water level exceeds the threshold,it can alarm locally or alarm remotely with the NB-IoT communication module.Experimental results show that the device can monitor the water level around the vehicle in real time,remind the driver to wading slowly,and promptly remind the owner to transfer the vehicle in the event of heavy rain to avoid economic losses caused by flooding.
