Abstract: This paper presents a realization of real-time dynamic data collection and signal analysis system based on Internet/Intranet both in software and hardware. By using ARM+DSP master slave system, embedded Linux and reasonable task-assigned strategy, the system demand for real-time and data transmission speed of network are guaranteed. Several key technical problems including Internet/Intranet used in industrial tests and diagnosis are discussed. And also, the main design and the workflow of the system are presented
