Abstract

An embedded file network server based on a seismic data stream includes a broadband power management module, a main control unit, a serial-port-to-RS232 module, a PHY bridge layer, an SD card, and a network interface. The main control unit includes serial port, an SDIO interface, an internal RAM, DMA units, and a MAC drive layer. The main control unit performs seismic data interaction with an external device through the serial port, and receives seismic data through an internal interruption, and the received seismic data stream is stored in the internal RAM. The internal RAM transfers the received seismic data stream to the SDIO interface and MAC driver layer through the DMA units. The SDIO interface stores the seismic data stream in the SD card for data backup. The MAC driver layer is coupled to the PHY bridge layer for inputting and outputting the seismic data stream.
