摘　　要：以嵌入式微处理器S3C2440为主控制器,数字式温度传感器DS18B20为测温元件设计了嵌入式温度检测系统。阐述了系统的软硬件设计与实现流程,重点介绍了DS18B20在嵌入式Linux操作系统下驱动程序的实现方法。该系统电路简单、运行稳定,操作简便,可扩展性好。The embedded temperature detection system was designed,which takes the embedded microprocessor S3C2440 as main controller and the digital temperature sensor DS18B20 as temperature measurer. The design and implementation process of system′s hardware and software are described. The implementation method of DS18B20 driver program in embedded Linux operating system is discussed emphatically. Operation results show that the system has simple circuit,stable operation,easy handling and good expansibility.
