| Abstract: | In the Development of SPOTE MWD/LWD system,implementidng a special research project on tools bus reliability achieved a MWD/LWD tools bus test system.The system is capable of automatic error-bits surveillance and statistics,provides a objective justice method based on Bayesian rule to evaluate the bus performance in physical layer and protocol layer.With the system,a series of experiments focused on the effects of interface circuit,transmitting distance and load support results in a connect-in criterion and... |
