| Abstract: | A network communication and recording system based on homemade ARCA-SOC and embedded Linux operating system is introduced in this paper. It supports TCP/IP network communication protocol and mass storage medium. It has strong points of self-monitor, low power consumption, high timing accuracy, high reliability of operation, 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 observation, strong motion observation and seismic exploration observation, etc. |
