Abstract
In consideration of high transmission rate and high reliability of the
coiled tubing drilling measuring instrument, through comparison with the MILSTD-1553B bus protocol, we proposed a modified CAN version to improve the
CAN bus as data transmission scheme for underground communication bus. Comparing the 1553 bus with CAN bus in terms of their basic principles, characteristics
and formats of data, the feasibility of CAN bus as underground transmission bus is
analyzed. In order to meet the demand of small size coiled tubing instrument, the
design of CAN bus controller based on FPGA technology and the improvement of
CAN bus protocol are put to enhance the stability and reliability of the CAN bus
protocol, meeting the requirements of the measurement while drilling. The modified CAN controller, which is the middle link of downhole instrumentation and
telemetry gauge, is equipped with high reliability and scalability.
