The Research And Implementation Of Well Logging Signal Process System Based On EOS

Multiplexed Production Logging Stack System can get all this parameters in only one times when we measure the well. It's can save much time and reduce the cost. Nowadays, we need various special IC to finish the task of code and decode. Every kind of coded signal need a special interface board to process it. This will make well logging more difficult. The more different signals, the bigger and more complex the instrument is. In addition, all these can reduce the reliability of the instrument. This dissertation mainly introduces the design and realization of the well logging instrument based on the embedded processor ARM EP9312. According to the theory of time-division multiplexing, I studied the method that sample different signals in one channel and designed the hardware of the well-logging instrument. All the work makes the instrument smaller and processes the signal in a digital way. In addition to all this mentioned before, it also discuss the design of software the system needed.
