基于multisim的便携式冷藏箱系统设计与仿真。 软件使用multisim11.0 ，里面有51单片机（mcu）模块 。在multisim软件中连电路，单片机要编程序，STT-T型铂电阻温度传感器实现温度数据的采集，然后软件仿真、单片机运行。冷藏箱需要显示温度，LED显示终端。保持冷藏温度，温控范围在-10~+10度之间。

-Reefer based portable system design and simulation of multisim. Software multisim11.0, there are 51 microcontroller (mcu) module. In the multisim software connected circuit, microcontroller to be programmed, STT-T-type platinum resistance temperature sensor to achieve temperature data acquisition, and software simulation, the microcontroller operation. Freezer temperature needs to display, LED display terminal. Kept cold temperature, temperature range between-10 to+ 10 degrees.
