摘要
Abstract
In order to have neutron lifetime logging function in Ellog logging system, developed are control and data processing system of neutron lifetime, and the solutions scheme of hardware and software is introduced. Based on the analysis of neutron lifetime tool data structure, expatiated are principle and method of PCM (Pulse Code Modulation) transmission signal encode and decode in which kernel chip is MCU(Micro Control Unit) microprocessor. Different software platforms obtain layer data, and accessing the hardware is completed by bottom device drivers. Datum are acquired and processed by up control software. The system transmission error code is lower, data acquisition real-time is good, software is stable and reliable. The system trials test for the EILog neutron lifetime logging control and data processing system succeeded in neutron lifetime logging standard calibration facilities of Petroleum Industry Metrology Center.关键词
