DREAM® For Windows



Other Information

Database Structure

In the database, DREAM® stores the pertinent information on all your equipment including technical specifications, drawings or pictures, machine condition including defects found, maintenance or corrective actions recommended, vibration measurement results, and so fourth. The contents of the database is displayed hierarchically as a Node Tree. The node tree contains three types of nodes - Machine Groups, Machines, and Diagnostic Units. Machine groups can contain machines and other machine groups. The number of groups, machines, and levels of the hierarchy is unlimited. Machines can only contain diagnostic units. The diagnostic unit is the part of the machine to be diagnosed by DREAM and can be a bearing, pump impeller, induction motor electromagnetic system, or other machine component.

Configuring Diagnostics

To enable DREAM to make condition diagnostics of the equipment, the operator configures diagnostic units in the DREAM database by entering the physical parameters of the equipment such as the type of bearing, the mains supply frequency for electric machines, the number of blades for a pump, or the number of teeth for a gear. Using this data, DREAM determines what measurements should be done to make diagnostics of the unit and automatically sets up the measurements in the database.

Conducting Measurements

Once the measurement units have been set up, you can create routes that can be loaded to a data collector for measurements, a very easy operation in DREAM. Just drag and drop the diagnostic unit to the route window. You can also drag an drop the whole machine or a group of machines. After the measurements are made, all the data are downloaded back to DREAM for diagnostics.

On-line Monitoring

DREAM most commonly acquires it's data for diagnostics and monitoring from a data collector such as the DC-12M but it can also be used in an optional on-line or stationary system monitoring mode using up to 16 DC-12Ms with each DC-12M having up to 16 input channels, or with PC based data single and multiple A/D card and multiplexer systems. The on-line monitoring mode allows a mix of frequent measurements for level based monitoring, condition by monitoring, and less frequent measurements for condition based monitoring, condition by diagnostics. See the monitor manuals for more information.

Automatic Diagnostics

DREAM provides automatic diagnostics of the units configured in the database and measured in the field. To make the diagnostics, select a diagnostic unit node in the node tree or in the image display, click the secondary mouse button, and choose the diagnostics command. DREAM will find all possible defects of the machine, display the symptoms that it used for diagnostics, tell you how long this unit can operate without maintenance needed, and either advise when it should be measured next or make recommendations on the maintenance or repair work to be done. Each of the recommendations will be substantiated with the corresponding defects found and each of the defects will be substantiated by marking or listing the corresponding lines in the spectra.

Information Display and Analysis

For a Group or a Machine, DREAM displays the condition summary or else the image on which you can mark the positions of all nodes of the next hierarchical level. For diagnostic units, DREAM displays the recommendations for maintenance, results of condition diagnostics, and symptoms for any defects found.

Extensive spectrum analysis functions are available in graphic display windows including waterfall plots, overlay, trend analysis, characteristic frequency cursors, harmonics, sidebands, and other functions. In this way, DREAM provides excellent tools for an expert to deal with those rare cases when the automatic diagnostics present uncertainties for the reasons for the changes in the vibration state of the machine.

A number of reports regarding measurement point configuration and conditions can be formed automatically by DREAM.

Planning Diagnostic Operations

Using its diagnostics, DREAM furnishes and estimate of the time period for non-failure operation of the machine, that is, condition prediction. After this periods expires, DREAM recommends making the next measurements and diagnostics. DREAM can automatically schedule these operations and create routes for the specific dates. For example, when the operator comes to the enterprise each day, he creates a route map for the days' measurements. DREAM enables one operator to control several thousand of machine components without missing any component failures.
