6. The peculiarities of the software "DREAM for Windows".
Question 6.1.
The software "DREAM for Windows" in intended to be used, as
you write in the documentation, to solve the problems of monitoring and
diagnostics that are connected with each others only partly. Would you be so
kind to describe the "D REAM for Windows" software in more detail and to clarify
how you separate the problems of monitoring and proactive diagnostics?
(The question was asked by the specialists of "Remont" enterprise from Moscow)
The question is answered by
Iosif A. Yudin. 17 March 1999:
The following diagram briefly presents the elements of the
"DREAM for Windows" application software:
In this diagram you can see the following functions:
Configuration of Machines and Units - means the
entrance of the diagnosed units' constructive parameters.
Vibration Measurements with external instruments,
for example the Data Collector DC-11, or via the measurement channels of the
on-line system with the following entrance of the results into the program
database.
Measurement Data Processing including the
monitoring and automatic diagnostics.
Current Information Display about the condition of
the units (in the form of a tree of conditions).
The Intermediate and Final Results Analysis
includes the reports.
The functions that are designated by the dash lines are executed only by the
on-line monitoring and diagnostics systems, so they are designed as separate
programs that are an addition to the "DREAM for Windows" software.
The problems of monitoring and diagnostics are solved in parallel and
independently of each other. To make a detailed diagnostics it is important to
select the measurement frequency bands, that include the main diagnostic
symptoms, in optimal way. So t he program itself implies strict requirements on
the diagnostic measurements. The monitoring algorithms give the user more
freedom enabling him to select by himself the type of measurements, measurement
points, the method of analysis and many other thin gs. To unite the strict
requirements applied to the diagnostic measurements and give the operator the
freedom to make the monitoring measurements both these measurements are
considered to be independent from each others even when they use the same measu
rement results. The monitoring and diagnostics expertise have also two
independent parts. The final decision is chosen by the program by the results of
the diagnostics, if only the operator does not select another decision.
