摘　　要：以单总线数字温度传感器DS18B20和16 bit超低功耗MSP430F149单片机为核心,以虚拟仪器软件LabVIEW 8.6为开发平台,设计了一个实时温度监测系统。将DS18B20采集的温度值经MSP430单片机通过USB接口传给LaVIEW进行分析和处理,实现温度的实时监测。实验表明,该系统具有体积小、精度高的特点。A temperature monitoring system was designed using digital temperature sensor DS18B20 and 16-bit ultralow power consumption MCU MSP430F149 as the hardware core,and virtual instrument software LabVIEW 8.6 as the designing platform.The digital temperature signals from DS18B20 was collected and sent by MSP430 to the LabVIEW which analyzes and processes the signals to achieve realtime temperature.The experiment proves that system has the characteristics of small size and higher precision.
