摘　　要：根据测量原理,测井仪器可以划分为声波类、电法类与放射性类三种。由于测量原理的差异性,不同测井仪器的内部结构与总线架构具有较大差异性,测井仪器的测试设备通常需要专用的测试电路,给现场仪器诊断、测试、维修带来了不便。通过分析国内外多种测井仪器的总线技术,以及多种类型的总线接口,设计出一种能适用于多种测井仪器的总线测试接口,分析研究了国内多种测井仪器的总线技术特点,分析研究了多种类型的总线接口,使用数值仿真分析了接口电路的功能,通过仿真实现了总线的从节点功能,测试表明此通用总线接口适用于国内外大多数测井仪器。该总线接口电路使得测井仪器制造过程中的整机检测与分节调试变得便捷简单,为仪器的现场快速诊断奠定了基础。According to the principle of measurement,logging instruments can be divided into acoustic,electrical and radioactive types.Due to the difference of measurement principle,the internal structure and bus structure of different logging tools are quite different.The testing equipment of logging tools usually needs special testing circuit.This paper analyzes the characteristics of the bus technology of many kinds of logging instruments in China,analyzes and studies many kinds of bus interfaces,and designs a universal bus test interface which can be applied to many kinds of logging instruments.It can test the bus of most logging instruments at home and abroad.The function of interface circuit is analyzed by numerical simulation,and the slave node function of bus is realized by simulation.The designed bus interface circuit makes the whole machine detection and section debugging in the manufacturing process of logging instrument convenient and simple,which lays a foundation for the rapid diagnosis of the instrument on site.
