In this paper, the embedded Linux is used as the operating system, and the embedded S5PV210 processor is designed to design an embedded temperature acquisition system. Based on the analysis of the Linux device driver based on the basic working principle discussed development often encounter interruption congestion handling, processing, I / O ports, and on this basis, realized s5pv210 embedded processor open, read, write, outside the ram of the character set by driver and the network drive on. Combined with the high precision temperature sensor DS18B20, to achieve the correct temperature collection, and through the Ethernet network to upload data to the host server.At first, the paper introduces the communication network characteristics of various devices, bus structure and transmission technology, and then introduce according to the principle of serial communication between MCU and PC, ubantu completed software design and implementation of data acquisition system, to provide users with a friendly man-machine interface, to control the acquisition system and display after the collection of the data. The use of serial data transmission, for the data acquisition system and the communication between the co
