Data Acquisition And Transfer System Based On ARM-Linux

Along with the development of communication technology, the application of wireless communication technology in industry field increases. Currently, the industry mostly adopt the wire or artificial way to acquire and transfer data, although it is simple and practical, but costs too many human resources and material resources, also restricts the extension of production adoption largely. So, it is urgent and necessary to select a relative economic, stable and efficient wireless transfer method.GPRS wireless network shows its advantages in telecommunication with the maturation of GPRS network technology. At the same time, the fast development of embedded hardware and software technology also helps introduce embedded production to every family. As a result, the wireless communication based on embedded system and GPRS network becomes one of the hot topics in application today.This system finishes the design of embedded data acquisition and transfer system based on ARM-Linux by using high-performance embedded microprocessor S3C2410 and GPRS wireless comunication module MC39i to construct a hardware platform, and using the embedded Linux operating system and TCP/IP protocol to build software platform.This paper summarizes the overview of embedded system first, then introduces embedded processor, embedded operating system and GPRS wireless communication technology briefly, offers the design scheme of embedded data acquisition and transfer system, also describes the development process of the system from the aspects of hardware design and software implementation, including building a hardware platform which centralizes on S3C2410 and MC39i, building a software platform based on embedded Linux operating system on this hardware platform, and realizes the data acquisition and transfer function finally.This system has certain advantages on multitask parallel disposal and procedure real time disposal, because it adopts high-performance ARM processor and embedded Linux system. This system suits for gas, oil field and electrics field, also has an encouraging prospect for development.
