1. A system for diagnosing a state of mechanical equipment, the system comprising:
a detection part configured to sense parameter values of individual components;
a state value derivation part configured to calculate a state value of the mechanical equipment in a time series manner from the parameter values;
a database configured to store the state value; and
a controller,
wherein the state value derivation part comprises:
a health index derivation part configured to derive health indexes of individual parameter nodes in a parameter layer from the parameter values;
a weighting derivation part configured to provide weightings for the individual parameter nodes in the parameter layer; and
a health index calculation part configured to derive or calculate the state value of the mechanical equipment by multiplying the health indexes of the individual parameter nodes by the weightings.
