摘　　要：针对暴雨天汽车涉深水行驶和停驻浸水易损坏问题,设计了基于NB-IoT通信技术的智能车辆防浸报警装置.装置利用超声波传感器测量车辆涉水深度,可预判水位上升速度,并动态调整测量时间间隔以降低功耗.同时设计了汽车开关检测电路判断车辆驶停状态,当水位深度越限时可本地告警,或通过NB-IoT通信模块远程告警.实验结果表明:该装置可实时准确监测车辆周边水位,提醒司机涉水缓速行驶,并在发生暴雨险情时通知车主及时转移车辆,避免浸水造成经济损失.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.
