DATA LOGGING

With the increase in the need for more Data and that would also include Meter Data e.g voltage data, power consumption data, temperature data, and humidity as examples there are growing numbers of engineers, scientists and technicians who need devices to record data for monitoring and troubleshooting purposes. Since more data could means more representative samples there are moves to produce advanced data loggers with multiple inputs and outputs, more storage capacity and faster processing so that any important event will not go unnoticed. To make life easier, these data aquisition systems can be designed for easy transport. Increased functionality also makes it convenient for technical personnel to view a trend in a smarter way. The applications are wide and are not only for the Smart Grid but also for machinery monitoring, network analysis, human related objectives and environmental concerns where sensors and meters of all types can be interfaced with the data logging computer and intelligently designed interfaces allow the flexibility for users to create organized tabular and graphical representations of the data streams they are monitoring or managing. Some refer to the GUI (graphical user interface) as more intuitive but we can also use the word "Smart."

Some of the more advanced systems even allow data points to be associated with relevant site videos so that events can be seen both graphically and visually from the site (time synchronized data) Data loggers have evolved with more options for smarter ways to retrieve, collate and transmit data in forms that are understood by those who need the important data to keep things running at an optimal level and well as encouraging diligent preventative maintenance objectives. They also have smarter redundancy designed into the products and abilities to employ polynomial algorithms to work together with realtime streaming data. More advanced test and measurement is most definitely a Smart activity.



     

Since a data logger or aquisition system now can be purchased with large amounts of data storage capacity and the ability to interface with multiple points it becomes more important to have a conveniently designed human interface that will save time since data loggers could be performing multiple tasks. Some of the more modern loggers now have touch screen capability as well as smartly designed menu systems that should be able to help increase a project's efficiency level.
 



     

There seems to be a million and one things an enthusiast could do with an analogue oscilloscope. This might be considered to be a Smart recreational application to those who have spent several thousands of man hours studying waveforms. Smart people know how to speak digital, but those even smarter speak both analogue and digital and are far more advanced since they can act as an A/D converter to people in the digital age who somehow lost their way. Obviously these technical groups are finding more innovative ways to encourage others to understand the complexities of wave forms but at the same time showing others that technical subjects can be fun and of course we know that some of the greatest discoveries ever made were because of someone enthusiastically trying something out. We have to believe that these are also Smart activities.


     




Analogue waves still need to be recorded, monitored and analyzed by scientists, technicians and engineers. The presentation above gives an interesting look into analogue vs digital but also educates us about the difference and might possibly encourage smart people to be interested in evolving technology which also includes the world of analogue to digital converters or to underestimate what an analogue specialist knows.
