摘    要:设计了一种基于HC单片机的井下仪器发射信号源,单片机利用内部功能模块产生PWM脉冲序列,经过D类功放放大,然后将滤波解调出的标准正弦波作为微电阻率扫描成像(简称FMI)测井系统极板的激励信号源。该基于PIC单片机的集成化模块为测井仪器中信号源的研制提供了新的方法。

关 键 词:单片机  信号源  PWM  微电阻率扫描成像测井

Abstract:A kind of logging tool signal source based on PIC single chip is designed.The single chip uses its interior function module to generate PWM pulsed sequence,after being amplified by passing the D class power amplifier,the filter signal is changed into standard sine signal,which is applied to Formation Micro-resistivity Image (FMI) well logging system of driving signal source.The integration module based on PIC single chip provides a new method for the developing of the logging tool signal source.
Keywords:PWM
