介绍了阵列感应成像测井仪调试台架的设计。根据阵列感应测井仪的结构特点,将仪器调试分为线圈、线圈系和整机三个层级,并从元件级设计了各调试子系统。该调试系统采用主从式结构,主机和前端机通过以太网互联。基于嵌入式技术的前端机通过扩展总线控制线圈、线圈系和整机调试子系统。扩展总线在硬件实现上借鉴了PC104的自堆叠结构,使前端机和各调试功能板形成积木式组合,也使系统具有良好的可靠性和可扩展性。该系统已成功应用于阵列感应成像测井仪的产业化过程,并为新型线圈及线圈系设计提供了良好的测试平台。
The design of the debugging bench of array induction imaging tool is introduced. According to the structure characteristics of the array induction logging instrument, the instrument debugging is divided into three levels: coil, coil system and machine, and the debugging subsystems are designed from the component level. The debugging system uses the master-slave structure, the host and front-end machine via Ethernet interconnection. Based on embedded technology front-end bus through the expansion of the control coil, coil system and machine debugging subsystem. The expansion bus draws on the self-stacking structure of the PC104 on the hardware implementation, which makes the front-end machine and each debugging function board form a building block combination, and also makes the system have good reliability and scalability. The system has been successfully applied to the industrialization of array-sensing imaging tools and has provided a good test platform for the design of new coils and coil systems.
