摘　　要：针对传统培养箱加热制冷器件能耗高、体积大且温控精度不高的特点,应用热电半导体对培养箱的温度进行调节。采用ARM920T架构的S3C2440AL处理器并配合外围设备,在Linux嵌入式操作系统上进行核心程序研发,并加入模糊自适应PID算法,以实现对培养箱温度的精确控制。试验结果表明,该培养箱的控温相对误差达到±1.1%。Aiming at the disadvantages of traditional incubator such as high energy consumption, big bulky and low precision, the thermoelectric semiconductor based on its Pehier effect is used to control incubator＇s temperature. This system is designed by using ARM920T processor S3C2440AL and the hardware driver programs developed on Linux embedded operating system, with aim of controlling temperature accurately. The experiment results show that the system can achieve the temperature relative error within ±1.1%.
