摘　　要：介绍一种基于USB技术的单片机温度采集系统,该系统是为了实现多点温度采集、并通过PC机实时监控温度变化而设计。在设计上采用AT89S51单片机作控制器,温度传感器选用了“单总线”数字温度传感器DS18B20,单片机与PC机之间的通信采用USB通信技术,从而使整个系统具有体积小,硬件电路简单,性价比高,用户操作界面简单、直观、实时性好等特点。文中从硬件电路和软件两个方面阐述了系统的组成与功能,介绍硬件电路设计和软件设计思想。The temperature acquisition system of microprocessor based on USB technology is introduced, which is designed for multipoint temperature acquisition. The real time temperature change is monitored by PC. AT89S51 microprocessor is adopted as CPU and single bus digital temperature sensor DS 18B20 is adopted. USB communication technology is applied between microprocessor and PC. So the system has outstanding advantages of small volume, simple hardware circuit, high percentage between performance and cost, simple and vivid user＇s operation interface, and effective real time. The composition and function of the system are introduced from the aspects of hardware circuit and software, and the design concepts of hardware circuit and software are also introduced.
