摘要
为实时监控某温室的温度,设计了测量温室小气候的温度记录仪。测温元件采用高精度数字传感器DS18B20,温度数据记录元件采用非易失性I2C接口器件AT24C04,显示元件采用微型AMPIRE128×64液晶显示器,信号处理器件采用AT89C51单片机。系统软件设计主要包括温度采集、I2C通信和液晶显示三个模块;对设计的硬件电路和软件进行了Proteus仿真,结果表明,该记录仪设计正确、运行可靠。
In order to watch and control the greenhouse temperature, the temperature automation preserving meter was designed, which was used to measuring the climate in greenhouse. The component measuring temperature is high-precision digital temperature transducer. The component preserving data is uneasily-missing I2C device AT24C04. The displaying component is mini AMPIRE 128×64 liquid crystal dis- play. The component processing signal is single chip AT89C51. The design of soft included three module that were respectively temperature gathering, I2C communication and liquid crystal displayt. The Proteus simulation results of the system＇s hardware and software show that the design is right and the system works reliably.
