PREDICTIVE MODULE
NEW WAVEFORM VISUALIZATION: ORBITAL PLOT
Searching for new tools that provide more assertiveness of the vibration spectra analysis, the Web Platform has received a new waveform visualization: the Orbital plot. This feature has presented itself as an essential option when a spatial representation of the movement is required, since it enables the visualization of the combined vibratory movement in two axes in a reference plane from the signals in the time domain. The feature is key analysis tool for vibrating screen motion analysis and for the identification of axis misalignment.
Due to the fact that the graph representation depends on the spatial position on a reference plane (chosen by the user), it’s possible to invert and select the pair of axes in an interactive way by using the options right below the graph plot, such as:
Obs: It is worth highlighting that the feature is available only for the triaxial Spectral Analysis that are simultaneously collected.
SPECTRAL ALERTS PER BAND
Aiming to customize the analysis of monitoring points, alarms per frequency band are now available, based on the metrics and resources of the Spectral Trend page. On the “Alerts” tab of the Spot Center, the user can set up many alert levels with different frequency bands, creating more effective and specific Spot monitoring. By selecting the option “+Alert”, a new drawer will be shown requesting the data from the user to create a new alarm.
In this feature, by selecting the “Spectral” option in the “monitoring” field, it’s necessary to insert: name for the alarm, type of metric (velocity, acceleration, displacement or envelope), monitored axes, metric (RMS, Haystack RMS, Peak-to-Peak, Crest Factor, etc), frequency band (specific or global), the levels (A2 and A1) and, finally, the trigger condition.
Obs: It is worth highlighting that the metrics depend on the associated DynaLogger model and on the parametrization defined for the Spot.
On the Spot Center, it’s also possible to view all added alarms in the form of tables and columns, bringing up information regarding each configured alert. On the DMA Dashboard, it’s possible to identify which alarms have been configured for the Spot when passing the mouse cursor over the icons of the “Status” column.
On the “Trend” column, also on the DMA, it’s possible to view which alarms were triggered in the last 7 days. When passing the mouse cursor over the icons, information regarding which alert was triggered each day will be shown. If an alarm was configured on a specific frequency band and metric, the information will also be shown with the event date.
The collection of triaxial spectra at 3200 Hz and 6400 Hz will, unlike the other options, not be simultaneous, as shown in the warning directly below the parameters. The spectra will be requested each axis at a time, in sequence, so the information will be plotted in just one graph.
SPECTRAL DATA FILTERING FOR MACHINES IN DOWNTIME ON THE SPECTRAL TREND PAGE
The Spectral Trend page has received a new feature: the machine downtime spectral data filter. With this, the spectral trend graphs supplied with various metrics can have their data easily filtered to consider only the spectra acquired when the asset was operating.
When selecting the button “Spectrals with operating asset”, the filter will be applied and the graphs will be updated to show the metrics considering only the periods that the asset was operating. This filter is based on a characteristic metric of the spectra. Right below the graphs, a list of all excluded spectra is shown, for example:
ADDITION OF SPECTRA ON PREDICTIVE ANALYSIS REPORTS
The Predictive Analysis can be done directly through the Web Platform in order to facilitate the flow of repairs within the company, generating reports that embrace the failures, the corrective actions and the deadlines to be executed. To get more assertiveness from this analysis, it’s now possible to include Spectral Analyses from the Spot using the “Spectral Analysis” tab when generating a technical report.
On the list of available Spectra, it’s possible to view a preview of a Spectrum by clicking on the eye (view) icon. It’s worth noting that, in all cases, it’s possible to select Spectra from different Spots and with various time periods for comparison purposes (for example).
Similar to the Spot Viewer graphs added to a Predictive Analysis, the Spectra also can be visualized in an interactive form on the generated report.
SPOT CENTER
Monitoring points (Spots) have had their user interaction pages redesigned. The main objective of the Spot Center is to centralize the monitoring point information and ease the configuration process, the visualization is now done in a “drawer” form, excluding the need to load a new page for such actions.
When selecting the create or edit button, the Platform will open a drawer which contains the information that the user needs to set-up.
The new concept of Spot interaction brings together the pre-existing configuration options (Alerts, Bearings, Frequencies) with the new functionality: viewing preferences.
SPOT VIEWING PREFERENCES
The Spot Center update as a new configuration mode of the monitoring points also introduces a functionality called viewing preferences.
With this new configuration option, visualization parameters can be defined when entering other Platform pages related to the Spot, such as:
- Spot Viewer: On this page, it’s possible to pre-define the default time period shown when accessing it. The feature impacts, in the same way as the period selection on the timeline, the way in which information from other fields is shown. e.g. timeline, graphs, events, predictive analysis, etc.
- Envelope Setup: In the Envelope Setup page, filters can be defined and customized so that when the user selects this option, it will already be pre-configured. In the same way, it’s also possible to define the maximum frequency, whose value can be customizable or even automatically defined by the Web Platform according to the main bearing registered, referencing the 4xBPFI (ball passing frequency inner) and the defined RPM.
- Spectral Trend: In the same way as the Spot Viewer viewing preferences, the Spectral Trend page can also be configured to show a pre-defined time period by the user. There’s also the possibility to pre-configure which graph types will be shown when accessing the page.
NEW ANALYSIS TOOLS ON THE WATERFALL OF SPECTRALS
The Spectral Waterfall is a three-dimensional (3D) visualization form of a group of spectra, aiming to highlight a possible failure evolution on the machinery. To increment the analysis potential of the tool, the waterfall now has frequency markers (automatic and customizable) along with the visualization of the Waterfall Spectral Envelope, also three-dimensional.
On the upper toolbar, the customizable (added by the user during Spot configuration) and automatic (RPM and bearings) frequency markers will be available to be added to the graph visualization.
On the upper menu, the option will allow the visualization of the Waterfall Envelope, that is, the demodulation of the spectra utilized in its construction. The tool is useful for identifying “hidden” failures, masked by frequencies outside of range of interest.
Obs: The same Spectral Envelope tools (for a single spectrum) are also available for the Waterfall Envelope.
INTEGRATED MODULE
GREATER FLEXIBILITY OF DELETIONS ON THE ASSET TREE
Aiming to facilitate the organization of the Asset Tree, users with an admin profile can now request the deletion of components and/or subsets which contain Spots and associated checklists.
When a user requests the deletion of items with lower nodes in the Asset tree hierarchy, an alert message will pop up showing that other items will also be affected, as below:
- Inspection routes: components and Spots will be deleted from the route, along with its associated checklists.
- Components and Spots: associated checklists and Spot data will be deleted.
Obs: In both cases, the checklist model will not be deleted.
ASSET PARAMETRIZATION EVENTS
When creating, deleting or editing subsets, components or Spots, an individual event is generated on the machine’s timeline, in order to enable a future audit regarding the affected items of each action.
The generated event brings information regarding the affected item (such as subsets, components and Spots), event data, responsible user and agent (mobile application, Web Platform or Gateway). In the “Settings” tab, it’s possible to identify the modified parameters on the event and, as with all timeline events, a comment tab is also available. In the bottom part of the window, a shortcut “Go to Spot (in this example)” allows the user to be redirected to the affected item page.
PLATFORM SHORTCUTS
The Web Platform shortcuts were already available on the data visualization tools, for example, zoom commands and frequency markers on graphs. Aiming to improve the user experience and turn the utilization of the solution easier, new shortcuts have been added to various Platform pages.
Obs: It is worth highlighting that the shortcuts shown per section work exclusively on that page, since there are other functionalities with the same keyboard commands although in different places of the Platform.
In order to hide the side help menu, the user should repeat the command (⇧ Shift + ?).
MACHINE, SUBSET AND COMPONENT CENTER
Machines, subsets and components have had their user interaction pages redesigned. The main objective of the machine, subset and component center is to centralize the asset information and ease the configuration processes, since its visualization is done in a “drawer” form, excluding the need to load a new page for such actions.
- Machine Center: can be accessed through the edit button in many Platform pages, such as: Asset tree, machine list, Machine Viewer, etc. It contains the existing settings as well as a shortcut to the Machine Viewer.
- Subset and Component Center: can be accessed through the edit button in the Asset Tree. These also contain a shortcut to the Machine Viewer.
DARK MODE VISUALIZATION
The DynaPredict Web Platform pages were reformulated to provide support in dark mode. The tool performs a contrast and replaces the color palette in order to have a black color as its base theme.
In order to activate this visualization mode, the user should select the profile icon on the top right side in any Platform page and select the option “Dark Mode”.
To return to the default visualization (light mode), the user should repeat the same process and select the option “Light Mode” in the same previously mentioned place.
SENSITIVE MODULE
NEW CHECKLIST TYPE: MANUAL MEASUREMENT*
*Feature will be made available on the release of v4.16.12 DynaPredict App
Sensitive inspection has now a new type of checklist, the Manual Measurement. Similar to the manual measurement question belonging to the “default” checklist type, the model can be used to configure questions where the inspector, on an inspection route, takes measurements with an auxiliary instrument and inserts the measured value on the checklist. There are several parameters and customizable units to be chosen from the “Metrics” field, such as: temperature, pressure, volume, mass, thickness, etc.
It’s also possible, for each checklist model, to associate A2/A1 alerts according to the pre-established rules from the Platform. In this way, if the inspector measures a value which exceeds one or more of the configured levels, an alarm will be triggered and will be shown on the main Platform pages: Asset Tree, Checklist Dashboard, Machine Viewer (Anomalies and timeline) and Checklist Report.
NEW CHECKLIST TYPE: BELT THICKNESS*
*Feature will be made available on the release of v4.16.12 DynaPredict App
Aiming for a more comprehensive sensitive inspection, another new checklist type made available is for Belt thickness. The checklist has been developed in order to provide historic measurements made with ultrasound of the belt’s thickness profile.
Concerning alerts, this model is different from the other ones on the Platform because of the nature of the measuring process. In this case, the value of A2 (min) must be smaller than the value defined for A1 (min), since the evaluation process considers the gradual thinning of the conveyor belt over time.
Obs: The measurement unit is fixed on millimeters (mm), due to the conventions of measurement processes.
When accessing the checklist report on the Web Platform, a graph will be shown representing the conveyor belt’s thickness profile using the points that were inspected. Similar to the other reports available on the Web Platform, it’s also possible to generate an automatic report and save it as a .pdf or print.
FILTERING FOR CHECKLIST MODEL TYPE ON THE CHECKLIST DASHBOARD
With the implementation of new checklist models, the Web Platform now has a filter which considers the type of checklist on the Checklist Dashboard. When selecting the “Advanced Filter” option on the top right side of the page, the field “Checklist Types” will be shown.
The filtering options are the same checklist types of the Web Platform: Default, Belt thickness, Manual measurement and Rolls.
LOCATING CHECKLIST MODELS ON THE ASSET TREE
Aiming to increase the user navigation experience on the Platform, the “Checklists” page of the sensitive module was modified to show the location of the respective checklist model on the Asset Tree.
The “Sub Workspace” column indicates the location where the checklist model was previously created, impacting directly on the user permissions for editing/creating according to the Asset Tree hierarchy.
