摘要
水位测量及控制电路主要由A/D转换、单片机控制、LCD显示、蜂鸣器报警和模拟排注水控制等模块构成,它能够实现水位的自动检测、水位自动控制和蜂鸣报警等功能。容器中水位高于设定值报警且模拟排水,水位低于另一设定值会报警且模拟注水,水位在两设定值之间则处于安全液位。
The level measurement and control circuit is mainly composed of A/D conversion, microcontroUer, LCD dis- play, buzzer alarm and simulation of filling and draining control circuit. The function of level detection, level control and buzzer alarm can be achieved automatically. When the level of the container is higher than the set value, it can alarm and simulation of drainage, it can also alarm and simulation of filling by the level below a set value, and the level in between the two settings is in a safe level.
