How to relax on the beach!

Full-scale vibration condition monitoring on a smartphone

Have you ever been lying on the beach and begun to wonder about the state of your LP turbines? Or maybe you’ve been out on business and anxious to know if that troublesome exciter bearing has settled down? Many people will be familiar with using their phone as a camera, music player, web browser, email client, calculator or even a navigation device, but not many will have anticipated using it for full scale vibration condition monitoring.

One of the many advantages of Prosig’s PROTOR Vibration Condition Monitoring System is it’s adherence to open standards and protocols. This means that it can easily take advantage of new technologies as they appear. Recently, Prosig undertook a study to examine the feasibility of using an Android based smartphone to remotely access one of its PROTOR systems monitoring a power station.

All PROTOR servers are configured to support VNC (Virtual Network Computing) access so connections can be made via any VNC client. By installing one of the free client apps available for Android it was a simple task to connect to the PROTOR server. This allows an engineer to access the full range of PROTOR diagnostic screens and access runup & rundown plots, mimic diagrams, trend plots, waterfall plots and all the other realtime and historic information available from the PROTOR system. Although an Android-based phone was used for this evaluation, similar VNC apps exist for the iPhone and other smartphones.

The monitoring and diagnosis of rotating equipment based on vibration analysis measurement is at the core of predictive maintenance systems. This type of system allows the condition and health of machines to be assessed. The PROTOR Vibration Monitoring System, designed and manufactured by PROSIG, provides reliable on-line monitoring of turbine generators, main boiler feed pumps and other auxiliary plant equipment. It provides both real-time and long-term historical access to the important vibration factors together with various plant process parameters which indicate the machine state.

Data acquisition with GPS tracking

The latest version of the Prosig’s CAN-bus/GPS measurement module is now available for the P8012, P8020 and P8048 data acquisition systems.

The CAN-bus module has been in use in the field for some time now, recording CAN-bus information for display and analysis alongside noise, vibration, temperature and other signals captured by Prosig’s P8000 systems. The module now has an option to capture GPS parameters in addition to CAN-bus data. The integrated software treats all analog, CAN-bus and GPS parameters in the same way so any mixture of parameters can be selected for display in real-time and subsequent processing. CAN-bus parameters can also be used start and to stop captures.

The data capture software now supports a realtime GPS track overlayed on a map. Velocity and altitude data measured by the GPS system can also be displayed alongside any other measurement channels in realtime displays. The latitude, longitude, altitude and velocity data is stored with with all the other sensor data captured by the P8000 system and is available to view and process in the resulting datasets. These signals can then be used to classify or select data for further analysis. For example you could choose to process data when the vehicle is on a particular road or a particular section of the track, or if you find an unusual event use the GPS data to give a position and time or the event.
