基于单片机的水温控制系统设计摘要温度控制系统能够说是无所不在, 热水器系统、 空调系统、 冰箱、 电饭煲、 电风扇等家电产品以至手持式高速高效的计算机和电子设备, 均需要提供温度控制功能。本系统的设计能够用于热水器温度控制系统和饮水机等各种电器电路中。它以单片机 AT80C51 为核心, 经过 3 个数码管显示温度和 4 个按键实现人机对话, 使用单总线温度转换芯片DS18B20 实时采集温度并经过数码管显示, 并提供各种运行指示灯用来指示系统现在所处状态, 如: 温度设置、 加热、 停止加热等, 整个系统经过四个按键来设置加热温度和控制运行模式。关键词: 单片机、 数码管显示、 单总线、 DS18B20.Based Temperature Control SystemAbstract Temperature control system can be said to be ubiquitous, water heaters, air conditioning systems, refrigerators, rice cookers, electric fans and other home appliances as well as high-speed and efficient hand-held computers and electronic equipment are required to provide temperature control. The system design can be used for drinking water heater temperature control systems and other electrical circuits. AT80C51 microcontroller as the core of it, through the three temperature digital display and 4 keys to achieve man-machine dialogue, the use of single-chip bus temperature conversion temperature DS18B20 real-time acquisition and through the digital display and offers a variety of operating light to indicate system now live in the state, such as: temperature setting, heating, and stop heating, the entire system through the four buttons to set the heating temperature and control the operating mode.KEY WORDS: Microcontroller, digital display, single bus, DS18B20绪 论及时准确地得到温度信息并对其进行适时的控制,在许多工业场合中都是重要的环节.水温的变化影响各种系统的自动运作, 例如冶金、 机械、 食品、 化工各类工业中, 广泛使用的各种加热炉、 热处理炉、 反应炉等, 对工件的水处理温度要求严格控制。对于不同控制系统, ...
