A network communication and recording system based on China-made ARCA SOC and embedded Linux operat-ing system is introduced in this paper. It supports TCP/IP network communication protocol and mass storage me-dium. It has strong points of self-monitor,low power consumption,high timing accuracy,high reliability of opera-tion,etc. It can serve up to 20 centers real-time waveform data at the same time. It meets not only the requirements of physical networking observation,but also virtual networking observation based on Internet in which real-time data transmission is required. Its ability of field recording also meets the requirements of portable seismic observa-tion,strong motion observation and seismic exploration observation,etc.
