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 divisionally, by a data server, the pneumatic control valve state information received in real time from the smart data analyzer to an online analysis server considering network bandwidth use amount, 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 performing data time synchronization that groups data included in the pneumatic control valve state information based on data collection times;
• and
• displaying, by a client computer, the diagnostic information received from the online diagnostic server, wherein:
• the smart data analyzer further generates detail analysis data for user detailed analysis for the pneumatic control valve by processing the sensor signal acquired from the sensor set in real time,
• the client computer receives the detail analysis data via the data server and the online diagnostic server, and includes an analysis tool such that a client is able to analyze a state of the pneumatic control valve based on the detail analysis data, and
• the data server transmits the pneumatic control valve state information to the online diagnostic server with a first time interval, and transmits the detail analysis data to the online diagnostic server with a second time interval which is longer than the first time interval.
