    Key Words：Bus technology; Fault diagnosis; Long-distance gas pipeline
    Abstract：With the development of pipeline, large number of electric valves have been applied to large compressor station and hub station, etc to resolve the digital communication of the intelligent instrument, controller and the actuator, and information transferring from filed operating device to advanced control system. The electric valve group is not controlled by traditional cable but bus technology, which enhances valve fault diagnosis and reduces investment. Therefore, the application of bus technology to long-distance gas pipeline station with great many of electric valves and complicated process is necessary.
