Application of Embedded Linux Interprocess Communication Technology in the Seismic Exploration

Abstract

Oil and gas resource as the most important part of energysource compositionits in China, its seismic exploration and development has great significance. And this requires development of new generation of high-precision digital telemetry seismograph. Shared memory, the common telecommunication mode between Linux processes becomes the preferred interaction means between applications of seismic exploration for its controlled capacity and speedy interaction rate. This article describes the stacked power station being constructed by the embedded microprocessor PPC405 and FPGA chip, as well as the transplantation of U-boot, Kernel and file system, the development of inter-process communication application on basis of shared memory, and finally the network interaction of telemetering digital seismic power station.
