Design of Test-bench System for Logging Tools Based on Embedded Structures
WU Wenhe · Well Logging Technology · 2009
A design conception of test-bench system composition for logging tools is introduced.Principal and subordinate structure is used,the host and front-computer are interconnected via Ethernet.The front-computer is based on ARM7 technique,and expanded I/O bus is defined,the core board and all kinds of specialized function boards are formed as the blocks combination.The design conceptions of core board and typical function board,and the design thoughts of embedded end software and main control software are discussed.Based on this conception,the test-benchs of serialization imaging logging instruments have been developed and designed for micro-resistivity image tool,array induction tool,multipole array acoustic tool and so on.
