摘　　要：介绍了基于国产方舟SOC及嵌入式Linux操作系统的数字地震观测网络通讯与记录系统.它支持TCP/IP计算机网络通讯协议,具有自监控、自复位功能,支持大容量固态存储器,功耗小,授时精度高,运行连续可靠,可以通过网络同时向20个客户端提供实时波形数据服务,满足固定台网观测、虚拟地震台网观测的实时波形数据传输的需要,也适用于流动观测、强震观测及地震勘探观测等.A network communication and recording system based on homemade ARCASOC 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 selfmonitor, 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.
