Data acquisition
wherever they are in the world. RTUs facilitate communication to local sensors and/or to an interface at a central monitoring location. At the same time, they provide remote access to control and monitor through standard HTML pages.
Benefits of RtUs Where maintenance of assets is factored out, knowing the status of the device before the end customer ensures better outcomes for all project partners. Where the asset could potentially develop a fault that prevents it from operating, the RTU allows maintenance teams to take preventative action. Another useful feature is being able to control the asset from a
smart device to ensure that it is fully functional. Again, without an RTU, it would require a visit to the site by an engineer. It is already possible to fit GPS modules to the RTU to provide a positioning of the system, which can be useful in terms of movement of smaller assets. RTUs can also help companies meet their environmental
commitments. With a growing focus on sustainability, ‘big data’ captured using RTUs allow accurate monitoring of emissions. In Asia, Ovarro’s TBox RTU technology monitors diesel generator systems 24/7, providing emissions data to a central reporting location. The centralised data can be accessed by the wider community through an Air Quality Index app on smart devices as a means of keeping their energy providers in check. In addition, for the benefit of the owner, the RTUs monitor the generator health, by tracking exhaust temperatures, heater exchange throughput and oil quality as part of proactive maintenance measures. Monitoring fuel use also benefits efficiency management and deters fuel theft. We can see that deploying RTUs on industrial assets is an
important element of capturing, interpreting and using big data from an industrial process. They give you full control of the asset, wherever it is located geographically, including remote, harsh environments. Once in place, the RTU gathers operational data and transmits it to a dashboard on a smart device or stores it in the cloud for trending and future analysis.
