Introducing EDAS WorkFlow - Process Driven Vibration Data Analysis
Most data acquisition processes are traceable and highly controlled. But how much effort goes into managing the interpretation of the data?
Do you get the same result no matter who does the data analysis? Do you have a way to trace what was done to get from raw data to published results? If you answered 'no' to either of these questions, you need a way to manage your work flow. You need EDAS WorkFlow (EDAS-WF).
EDAS-WF is a task-driven analysis environment. Each task within the environment plays a specific role in the overall process. Work performed on any data is logged in a database to provide traceability and guarantee results follow established, company guidelines. Workflow operates on many data formats, freeing you from the hassle of translating data. Collaboration is a reality thanks to the database backbone.
Check out these benefits:
- Consistent test analysis results and reports from one project to another and one analyst to another
- Traceable analysis steps
- Relies on official data set only
- Numerous file types supported
- No need to spawn new data
- Better management of personnel
- Use of appropriate skills at each step in the process
- Better utilization of personnel among similar groups/divisions
- Higher efficiency through collaboration and parallelization
- User Friendly - each task is wrapped in a wizard guiding you through each step
- Easy to buy, maintain, use and train
- Can be adapted to your existing infrastructure or purchased with all required network components
The Base Software Package for EDAS-WF includes the following:
* Oracle is a product of the Oracle Corporation. Additional software licenses may be required.
- Support for Oracle* or SQLite databases
- Administrative tools for data, user and group management. Administrators can limit which tasks can be performed by users preventing untrained users from doing work they are unqualified to perform.
- Support for numerous, open format file types
- Activity tracking and reporting
- Task specific reporting
- One WorkFlow seat
- Three Process Tasks including
- File meta-data editing - allows meta data associated with files in the database to be edited and/or supplemented to include key words or descriptions. These meta data are used by the analyst to find data they need to work on within the database. Users can query within all fields to find key words or phrases including project number, test facility, operator, description, signal name, or any of literally hundreds of possible file identifiers.
- File Processing Options - establishes rules for how to process signals within files. Because instructions for processing signals are not always stored in all data sources, this task guides users to set FFT processing characteristics like ensemble size, resolution, bandwidth, and window function. You can even set multiple sets of rules for how to process any given file. Because File Processing Options are only called when files are processed, it eliminates the need to spawn new data.
- File Export - exports data in EDAS native formats (frequency domain and time domain) so that data can be viewed using our free, fully featured data viewer, EDAS-DV. This allows users to view data from any supported dynamic data format with our free viewer. EDAS-DV produces interactive engineering graphs like FFT magnitude and envelope plots, Campbell diagrams, strip charts, history plots, and more.
* Oracle is a product of the Oracle Corporation. Additional software licenses may be required.
EDAS WorkFlow can be easily upgraded to provide more functionality to further streamline your analysis process and standardize your output. The following upgrades are available:
- Additional WorkFlow Seats - each WorkFlow seat has access to all available tasks. Administrators can control user access to tasks.
- Noise Editing Task - this task contains tools for dealing with various kinds of signal noise which always makes data analysis more difficult. Noise editing can be performed using automatic tools, a signal health sheet or manually by simply drawing polygons around regions of noise as displayed on interactive engineering graphs. Spectral values in the frequency domain identified as noise are "flagged" so they are noted, or even ignored in subsequent process steps (exporting or reporting for example).
- Signal Reporting - this task produces standardized reports containing information about how the signal was processed and various engineering graphs. Some reports contain a tabular listing of maximum frequency domain responses with these noted on the engineering graphs. Reports can be produced in Adobe PDF format or as PNG images to facilitate reporting of results to others on the team. A record of all reports generated is maintained in the EDAS-WF database with a link to where the report was sent.
- Additional Tasks - many new tasks are currently be developed and will be available for upgrade as they are released. Check back often to see whatŐs new or sign up to be notified of new task releases.
WorkFlow controls the overall analysis and data management functions on the WorkFlow Network. Data produced by EDAS-DS network flows up to centralized long term storage with tape back-up capability. A database server and the WorkFlow Compute Server perform all analysis and data management tasks seamlessly. Popular database engines like Oracle are supported. EDAS provides every aspect of this solution, hardware and software, so you can focus on what you do best.
The main interface for WorkFlow shows data files selected by the user for analysis (top left), the available tasks (top right) and the history of work performed on the selected file (bottom). Files are easily added to the workspace by simple meta-data query. Tasks can be user specific. Work performed by any user is shown in the work history.
Doing work in WorkFlow is easy. Simply select the file or files you want to work on, then choose the task you want to run. Each task has an easy-to-navigate set of steps that turn green as you complete them. This approach minimizes the time required to become productive and focuses appropriately skilled personnel on specific tasks.
All work performed on any file by any user is completely tracked in the WorkFlow database providing an effective way to manage your analysis project. All work is time-stamped. Detailed reports of work performed are available with a mouse click.
The Processing Options task and the Export Data task serve as your interface between data from many open data formats and EDASŐ free form viewer, EDAS-DV. EDAS-DV is a free application that allows users to interact with their data. If you have dynamic data files from other data acquisition systems but have struggled to translate the data WorkFlow is your solution. WorkFlow allows you to work with data from many different sources as though it were all the same.
Create beautifully formatted reports with the optional report generation task. Here is a standard Campbell Diagram summary plot. One of these plots is created for each signal in each file selected. Here are samples of our Campbell diagram, envelope plot, overall, and order tracking all combined to make it as easy as possible on our users. A summary table gives tabular values of maximum responses.
