针对当前储液罐液位控制中液位控制精密度不高、控制过程中可能存在过冲以及水位控制中电机不能同时进行抽水和注水等问题,系统采用单片机作为控制核心,根据PWM控制方式,设计了按键电路模块、数字显示模块、超声波传感器模块、集成H桥模块以及整个软件系统,完成了一套智能液位控制系统.经过软硬件的设计后,调试达成水位低限3 cm高限5 cm的水位智能控制功能,并带有警报功能和水位显示功能,测试简便,人机交互好,在同类项目中达到了较高的水平.%In view of the liquid storage tank level control level control precision,control process may simultaneously pump and injection problems such as overshoot and motor water level control cannot system adopts MCU as the control core,according to the PWM control mode,designed by key circuit module,digital display module,sensor module,ultrasonic integrated H bridge module and the software system,to complete a set of intelligent liquid level control system. After the design of hardware and software,debugging intelligent control function level reached the low water level limit high limit 3cm 5cm,and with the alarm function and level display function,the test is simple,good human-computer interaction,reached a higher level in the same project.
