System and method for diagnosing pneumatic control valve online

A method for diagnosing a pneumatic control valve online, comprising:

• measuring a state of the pneumatic control valve, by using a sensor set attached to the pneumatic control valve;
• generating, by a smart data analyzer, pneumatic control valve state information for online automatic diagnosis of the pneumatic control valve by processing a sensor signal acquired in real time from the sensor set;
• transmitting, by a data server, the pneumatic control valve state information received in real time from the smart data analyzer to an online analysis server, and storing the pneumatic control valve state information for a predetermined time period;
• generating diagnostic information, by the online diagnostic server, by determining whether the pneumatic control valve is in an abnormal state by comparing the pneumatic control valve state information with pre-stored normal state data of the pneumatic control valve;
• and
• displaying, by a client computer, the diagnostic information received from the online diagnostic server.

A storage medium readable by a computer for diagnosing a pneumatic control valve online, comprising a processor included in the computer to perform:
