ESS-300 Environmental Vibration, Acoustic & Structural Monitoring

The ESS-300 package includes all of the features of an ESS-200Environmental Vibration & Acoustic Monitoring package plus the VES-4000 Basic Modal Analysis and VES-4700 Operational Modal Analysisoptions.  Macro-programming is used in ME’scope to carry out continuous multi-channel data acquisition, post-processing of vibration and other engineering data, and storage into an archival Database from anywhere on a network

The Environmental Monitoring Console software in this package is used to graphically monitor the data from each monitored site using Trend plots, Gauges, and Warning Levels.  Warning Levels can be applied to each monitored parameter, and to frequency spans of spectrum data. ODS’s can be displayed in animation on a 3D site model from a cursor location in archived time waveforms or frequency spectra. Multiple copies of Console can be installed on any computer, tablet or hand-held device running Microsoft Windows.

Network Software. ME’scope can be connected to the archival Database either from the same computer or remotely using a wireless modem, cell phone modem, or an Ethernet network cable.  The Database can also beinstalled in the cloud, and assessed by Console and ME’scope over the Internet.

Hotkeys. Hotkeys are defined in ME’scope to initiate the execution of macro-programs. The same Hotkeys can be used in Console to remotely control the acquisition and post-processing being carried out by ME’scope.

Database Connection Files. All access to the Database is controlled by creating and distributing secure DCF files (Database Connection Files). DCF files are created with the DCF Manager software, which requires an administrator user name and password.

Operational Modal Parameters. This package also includes modal parameter estimation (curve fitting) algorithms for obtaining operating mode shapes from operating or output-only data acquired while a Machine is running. The modal frequency, damping, and mode shape components of each operational mode shape can be monitored in real time, and Warning Levels applied to those parameters to detect mechanical faults due to changing physical properties.

Archival Database

Each monitored site can have a variety of data stored for it in the archival Database;

  • Multi-channel vibration and other data is acquired, post-processed and stored by ME’scope into the Database for each monitored site.  All data is archived in the Database as a snapshot with a date & time attached to it.  A snapshot can contain any of the following types of data; Monitored Shape Table, Animation Shape Table, up to three Data Blocks containing multiple Time, Narrow-Band or Octave-Band Traces.
  • Monitored Shape Table. This table contains monitored parameter values that were obtained by post-processing data in ME’scope. This ME’scope Shape Table can contain multiple shapes and shape components. Each shape component contains a monitored parameter. Each shape component can be trended in a Trend plot, and have Gauges and Warning Levels assigned to it.
  • Warning Levels. Each monitored parameter can have up to six Warning Levels assigned to it.  Each Warning Level can have up to three positive values, (Alert, Alarm, & Abort), and three negative values.  Warning level values can be defined either as absolute values (in engineering units), or as relative values (relative to Baseline values).
  • Animation Shape Table. This table can contain ODS’s, mode shapes, or vibro-acoustic shapes. Shapes in this Table are displayed in animation on the 3D Site Model in Console.
  • Three Data Blocks. Up to three ME’scope Data Blocks can be archived for each monitored site in the Database. Each Data Block can contain multiple frequency domain, time domain, or Octave Traces. ODS’s, mode shapes, or vibro-acoustic shapes can be displayed on the 3D Site model from a cursor position in the Traces.
  • 3D Site model. Each test site model is displayed in Console with test point Icons which depict the sensor locations on the site. Hovering the mouse pointer of each Icon displays the gauge values and Warning Levels for the test point.
  • Archive FIFOs. Each site has four different First-In First-Out (FIFO) storage areas for storing snapshots of data; Short-Term, Long-Term, Warning Level Crossed Events, and User-Defined Events. The storage Rate & Length of the Short-Term & Long-Term FIFOs can be specified in minutes, hours, days, weeks, or the maximum rate possible. The Event Storage parameters include Number of Snapshots Before, Number of Snapshots After, and Total Number of Events to save in the FIFO.  All FIFO storage parameters can be changed “on the fly” during monitoring.

Console Features

  • Site Gallery. All sites being monitored are displayed in the Site Gallery. Each site has status indicators including, Monitoring On Line/Off Line, time elapsed since last archive, surveillance camera live stream.
  • Site Tree. All of the data for each monitored site is represented in a Site Tree Console. All data for a site is conveniently displayed in graphics panels either by clicking on the data in the Site Tree or by dragging & dropping it onto a panel.
  • Gauges. A Gauge can be assigned to each monitored parameter and displayed in Console. Each Gauge displays the current value, baseline value, and warning levels assigned to the Gauge.
  • Event Log. When new data is archived in the Database from ME’scope, it is checked for warning level crossings by the Database service. All warning level crossings are logged as events in the Database, and displayed in the Event Log in Console.
  • Email or Text Notification. Notifications of warning level crossings can be sent by email or cell phone text message by entering the appropriate email addresses and phone numbers into Console.
  • Trend Plots. Archived parameter values can be displayed in a Trend plot in Console. A Trend plot shows the archived values of each monitored parameter. The horizontal time axis displays the time at which each parameter was archived.  Warning levels assigned to each parameter can also be displayed together with the trended parameter values.
  • Trace Plots. Archived Data Blocks of spectra and time Traces can also be archived as part of a snapshot. The Traces associated with a particular snapshot are displayed by clicking on the monitored data in a Trend plot. Traces can also be displayed by clicking on them in the Site tree.
  • Trace Gauges. Multiple Gauges can be defined over frequency spans or time spans on each Trace. Each Gauge can have up to six Warning Levels assigned to it. This capability is particularly useful for detecting order-related vibration levels due to machine bearing faults, gear teeth faults, and other faults in rotating machines.
  • Interactive Shape Animation. If an Animation Shape Table is archived in the Database, ODS’s, mode shapes, or vibro-acoustic shapes can be displayed in animation on a 3D Site model.  Alternatively, shapes can be interactively animated from the cursor position in an archived Data Block of Traces.
  • Hotkeys. Hotkeys can be defined to execute different macro-programs in ME’scope for each monitored site. All Hotkeys can be executed from Console to remotely control the execution of macro-programs in ME’scope.
