The Design of Intelligent Water Level Alarm Device Based on Single Chip Microcomputer Control
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 ana-log-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.
