Abstract: Data acquisition system is a comprehensive monitoring system based on computer,
communication , electronic technology , and industrial control.In this paper, based on embedded Linux data acquisition system hardware and software design. To improve system performance and respond to real-time multi-tasking capabilities, the hardware used on the ARM9 microprocessor technology, and transplant the Linux operating system, the system's reliability and scalability to improve. The characteristic of embedded Linux has been fully utilized in the design. There are five modules of the system: data acquisition module, data processing module, data communication module, and data diagnose module. Embedded Linux operating system will be the introduction of data acquisition system design and accelerate the development of the system to facilitate the future expansion of the functions and improve the observation data timeliness and accuracy, and the observation of automation.
