基于单片机的饮水机缺水自动保护控制系统设计

Design of automatic protection control system for water dispenser based on single-chip microcomputer

文章以STC89C52为主控器件,设计了一套饮水机缺水自动保护控制系统,并详细介绍了防干烧的可靠性设计以及硬件电路各模块的电路设计。系统以非接触式液位传感器和数值温度传感器为检测手段,结合继电器“串联”控制的设计方案,实现饮水机缺水时可靠防干烧的目的。

The article uses STC89C52 as the main control device to design an automatic water shortage protection control system for a water dispenser,and details the reliability design of anti dry burning and the circuit design of each module of the hardware circuit.The system uses non-contact liquid level sensors and numerical temperature sensors as detection methods,combined with a design scheme of relay“series”control,to achieve the reliable prevention of dry burning when the water dispenser is short of water.
