八路温度采集显示系统设计

摘 要 在实际生产和生活等各个领域中，温度是环境因素不可或缺的一部分，对温度进行及

时精确的控制和检测显得尤为重要。 本次设计在控制成本的前提下，设计了一款高精度、可同时检测八路温度并液晶显示器对各路温度值进行显示的温度检测显示系统。该系统以AT89C51为控制核心，采用可编程单总线数字式温度传感器DS18B20进行温度采集，八路温度值LM041L液晶显示器显示。系统正常运行时，其测温范围为-55℃～+125℃，该系统在现代电子工业飞速发展的时期有良好的应用前景。 关键

and detect the temperature promptly and exactly. It has designed a high precision temperature testing system in the base of lost control, which can inspect eight route temperature at one time and show each route of temperature by LCD. AT89C51is adopted as control core in this system. Its sensors for temperature is single bus digital DS18B20, sending temperature to LM041L LCD to display. When it operates normally, it?s temperature ranges from -55℃ to +125℃, the system has a good application prospect in the morden period when electronics industry developing rapidly.
