Abstract

Abstract:

As the next generation of seismic prospecting instruments, the high precision telemetric digital seismic instrument plays an extremely important role in China's seismic prospecting and development of oil and gas resources. Embedded Linux technology is a high performance and low-power consumption embedded system solution based on embedded microprocessor, which provides a new way to develop novel telemetric digital seismic power supply. The paper presented the hardware system of a double layer stack based power supply constructed with PPC405 high performance embedded microprocessor and FPGA chips, transplanted U-Boot, embedded Linux kernel and JFFS2 file system core, and developed drivers and application programs related to power supply on the hardware framework, and achieved data transmission and network interactive function of telemetric digital seismic power supply.

Key words: embedded Linux technology, telemetric digital seismic instrument, power supply, data transmission
