This paper presents a temperature collection system which is based on embedded system, using the embedded terminal to do data collection will have a better man-machine interface and high stability. This article describes the environment of hardware development, bootloader boot process, Linux system architecture ,Linux kernel-related architecture, root file system architecture and other related knowledge. At the same time, this design mainly completed the programming of DS18B20s bottom-level driver , the configuration and compilation of the Linux kernel and the design of QT top-level application program in software; in hardware mainly implemented design of the DS18B20s circuit and build the cross-tool development environment. Through synthesized debugging this project finally realized the design of the temperature collection system which was based on ARM9 embedded system. The data collection terminal based on embedded system generally has the features of better human-machine interface and hardware and software can be cut, while using the mini2440 development board to do a embedded development platform will have the properties of low cost, low power consumption, small size, high development potential. Good performance of the embedded systems makes t
