本实验以LabVIEW可视化图形编程开发环境为平台，使用声卡和温度传感器加外围电路，测量和显示外部温度变化，并控制风扇和加热丝进行相关操作，使一定空间范围内的温度保持基本恒定。通过实际应用，加深对LaVIEW开发环境和实时控制的理解-this experiment visualization LabVIEW graphical programming environment for the platform, and the use of sound card plus the external temperature sensor circuit for measuring and displaying the external temperature changes, and controlling the fans and heating wires related operation, so that a certain space within the scope of maintaining constant temperature. Through the practical application LaVIEW better development environment for real-time control and the understanding
