A plant diagnosis system friendly to a user (a plant-operating organization)
for
identifying an abnormality of an objective plant or machinery thereof, is provided.
The plant diagnosis system includes a diagnoser's sub-system including a diagnosis
computer and a terminal for a diagnosis expert and is connected via a network to
a user's sub-system including a terminal for communicating with the diagnoser's
sub-system. The plant diagnosis system provides a simple but repetitively available
primary diagnosis and a detailed secondary diagnosis including the expert's judgement,
which are selectively available on the user's initiative. The diagnosis computer
receives a diagnosis request and plant state variables of the plant or machinery
and executes the primary diagnosis and a part of the secondary diagnosis based
on the plant state valuables.
