摘　　要：基于单片机控制的水位报警装置,安装于路桥涵洞、城市地下道等合适位置,在道路积水严重的情况下,可实现声光报警,提示行人或各类型车辆谨慎通行。基本设计思路是:首先通过水位传感器采集模拟信号经模数转换器转换后形成数字信号,输入到单片机中进行分析判断,然后根据水位高度的不同输出不同的控制信号,控制信号经过光电耦合器后,驱动对应的报警模块进行声光报警。A water level alarm device controlled by a single chip microcomputer is installed at suitable locations such as roads,bridges,culverts,and urban underpasses.In the event of serious water accumulation on the road,it can achieve audible and visual alarm to remind pedestrians or various types of vehicles to pass cautiously.The basic design idea is as follows:firstly,the analog signal collected by the water level sensor is converted by an analog-to-digital converter to form a digital signal,which is input to the microcontroller for analysis and judgment;and then,different control signals are output according to the different water level heights.After the control signal passes through the photoelectric coupler,the corresponding alarm module is driven to give an audible and visual alarm.
