Kinematik marker

kinematik marker follow FFT Tachometer

The Kinematik marker can now be associated to the speed of the tachometer. So during a Run up the kinematik marker will automatically move inside FFT spectrum in funtion of the speed.

How to used : Select a Tachomter on FFT tab from GoToResult page.

Then Display an FFT spectrum. Select a kinematik marker ans put it on the windows.

Now this marker will be link to the FFT speed.

Then on properties, you can link (or not) this marker to the speed.

Database include on install

Now the excel kinematik database is installed automatically. You will now have database including bearing from NSK , SKF, FAG, SNRn, GMN, INA, RHP.

On the install folder the excel database is here : "Data\Markers\Markers\Kinematic\"

Direct access to database

The open folder, will directly open the folder where excel kinematik database is stored. So you can now edit it easily if you need to add conematic configuration of a rotating machine.

Video

Oros have launch a youtube channels here :

OROS Youtube channels page

We have include tutorial vidéo on this wiki, to help you to use the OROS software

DC simulated

The DC simulated allow you to inject up to 32 external DC channels in NVGate from external source (exemple : GPS, weather station, external can bus...). The frequency sampling is up to 15 sample / seconds. Thanks to the python developer toolkit, a developer can easily develop an interface to inject the value inside NVGate. The GPS and weather station below have been develop using the DC simulated.

This option is include with the reference ORNV-VI-DC (wich also include the Virtual input).

How to use:

on acquisiton Tab, select connect input, select the DC inputs and select the DC simulated channels.

This channels can be activate and be put inside recorder and/or waterfall like any other DC channels.

The settings Value (wich can be controlled by an external software) will change the value of the inputs.

The others DC simulated settings details are explain on the front end settings page.

GPS

Thnaks to the "DC simulated channels" we have create an Add-on for record a GPS.

The gps have the following features

• Record the X-Y GPS coordinates.
• Record and display the speed profile.
• Use the speed profile as a waterfall reference .
• Creat a .gpx and Display it on an internet website if you have Internet connection).

You can visit the dedicated page to download it and advanced configuration. : https://wiki.oros.com/wiki/index.php/NVGate_DC_Simulated_Manager

We have 2 ways to acquire the GPS position, android phone or GPS Compliant with NMEA 0183 standard.

Serial GPGGA GPS

We are compatible with GPS USB Serial Interface Compliant with NMEA 0183 standard GPGGA

We can advice the GPS USB Navilock NL-602U but other GPS will work.

Android GPS

GPS data can also be retrieved using Android ADB (Android Debug Bridge). If you plug your android phone, we can inject the GPS position inside NVGate.

How to used

Once the gps is plugged and configured, click on inject data, this will put the value on the DC simulated inputs.

Then you can use these channels on NVGate.

If you need to record the data. click on connect input, go on DC input tab, then drag and drop the DC simulated channels on recorder.

If you have record the data you will be able to create a .gpx file

Creating and visualize .gpx file

We can create a .gpx from an .oxf (OROS) signal file. a .gpx is gps file to follow the

You need to click on Convertsignaltogpx.

This will open the windows below.

Select the signal file than you need to convert and click on load data. You can modify the channels if needed. Click on create .gpx. The .gpx will be put on the folder "attachement" of the NVGate project.

If you want to visualize the .gpx we advice to use the website : https://www.gpsvisualizer.com/ Clicking on "Click here to visualize the .gpx on a website" opens an website allowing you to plot the gpx on a map.

Weather station

Precipitation, wind speed/direction, pressure, temperature, pressure can prejudice sound pressure levels or need to be record when you are doing sound measurement.

Thnaks to the DC simulated channels, we can now enter manually the value or we can connect a weather station to NVGate.

Manual

The user can enter manually the weather value.

Davis instruments weather station

You need the 3 elements to make it work

- 6322OV Wireless Vantage Pro2 Integrated Sensor Suite

- 6316 Wireless Envoy

- 6510USB WeatherLink Data Logger.

This weather station provide Accurate, reliable weather monitoring with real-time data updates every 2.5 seconds. Sensor suite includes outside temperature and humidity sensors in a passive radiation shield; wind speed and direction; and rainfall.

Note : The weather Station need to pass by OROS SA for configuration.

Other weather statio

Please contact OROS to check the posibility to import the data. (paid service)

DC Dynamical sensor y = ax+b calibration

It is now possible to calibrate a dynamical sensor in "DC" or "DC floating" coupling using 2 values, then the software will automatically compute sensitivity and offset to obtaine the "y = ax + b" formula.

For using it, first create a DC sensor on the sensor database. Then apply this sensor to a channels.

Now on the calibration part, you can calibrate it using 2 values. Then the software will automatically and apply the sensitivity and offset.

Remove a sensor from history

If you have done a mistake during a sensor calibration, you can now delete a value from calbration sensor historic.

You need to ho on historic , select the sensor, select the value that you need to delete , then click on remove.

Add on : Human body vibration

The OROS Body Vibration tool allow you to evaluate the affect of vibration on the human body according to standards ISO 2651 and ISO 5349. These standard define measurement practice and vibration signal analysis to evaluate the affect on health and and comfort of environmental and equipment vibrations on the Human body.

The ISO 2651 describe the affect on health and comfort of vibration on the whole-body in transportation system, and the ISO 5349 the affect on health of vibration on hands and arms when manipulating machine-tools or vibrating objects.

This is a post analysis toolkit, operating after the recording of the signal. it will calculate time-weighted signal of acceleration and specific indicators both defined in the standards.

Standards compatible: international standards about whole/body vibration including: ISO 5349, ISO 8041, ISO 2631-1 and ISO 2631-5.

Whle/body Vibration Indicatiors include : VDV, MSDV, MTVV, Weighted raw, al(ISO 2631-5), D(ISO 2631-5) are available. RMS, Peak, Crest, peak-Peak, are also available in NVGate plug in.
