The paper designs a water fuzzy control system. STC89C52RC single chip is designed as the water fuzzy controlling core of the system. The system has several main achievements such as we can set the water height artificially. Using a LCD1602 can display real-time height and setting height and achieve water height control and height alarming beyond the limited height. The system achieves automatic closed-loop control to make the water height reach the setting value through software programs.%本设计以STC89C52RC单片机作为单片机给水模糊控制系统设计的控制核心,主要实现:人工设定液位,利用LCD1602显示实时液位和设定液位,恒液位控制,液位越限报警等功能,通过软件程序实现系统的自动闭环控制,使容器内液位达到设定值.
