Display Induction Logging Tool Is Real-time Monitoring And Control Unit

In order to track the international petroleum well logging advanced technology, using the modern integrated electronic technology, the computer technology and the signal processing technology, a digitized array induction-logging scheme based on the distributed acquisition and control structure is presented in this thesis. This scheme includes three major parts: the logging information relay unit, the real-time measurement and control unit, and the acquisition processing unit, among which the real-time measurement and control unit is my own topic research subject. Take the characteristics of hard conditions and the real-time multi-functions of the measurement and control unit, the detailed scheme is designed, and its concrete function targets are given. It is used high performance TMS320LF2407A DSP controller and thermostable, low power electric circuit components to design the system electric circuits including digital control core electric circuits, transmitter drive circuit, control drive circuit, and then to construct the real-time measurement and control unit hardware platform .The application software of measurement, control, communication is developed. By means of the hardware and software debugging, the systematic association and the performance index test, the functions, such as, the real-time monitor including system voltage and temperature variable, the working mode switch, transmission and acquisition sync hronization control, communications, are realized. And thus the topic original goal is achieved.The success of the digitized array induction log development satisfys the urgent demand to advanced logging tool in well logging field, and enhances the domestic logging technique level. The measurement, the control, the communication technique, and low-power design, reduced EMI design, which are studied in the subject, have very strong usability. The high performance components, the electric circuits, and the devices in the subject have the military performance, and can he reference to the military equipments development.
