The MYeBOX project is a shift in concept compared to previous instruments.
CIRCUTOR has numerous measuring instruments with different features depending on their area of application.
They can have higher or lower resolution or accuracy, measure different parameters, feature numerical or graphical displays, and more, but they are all basically structured like the block diagram shown below:
They always include a sensor system, a data collection and processing element, a graphic user interface and optional communications ports and/or alarms. The units are designed and configured for specific functions, providing the user with information in a predefined way.
The MYeBOX project is a shift in concept compared to previous instruments. Not only is the screen separate from the unit but the architecture has a completely new design in which the hardware (instrument) is completely independent from the application.
The unit is configured and regulated remotely to deliver the information needed by the user at any time and place.
It was designed to be a versatile unit utilised by a very high number of users, allowing them to record electrical variables and send them to external software for interpretation.
This new architecture will provide different kinds of information and conclusions in many areas of application. Therefore, the unit will be easily customisable to be able to adapt to all the client's needs and technical skills in real time, using a very user-friendly language.
One of the main advantages of this unit is that it enables increased energy efficiency and proper use of renewable energies.
For example, MYeBOX can be connected to the network and communicate with the inverter of a renewable energy system via Wi-Fi to analyse disturbances, network flows, etc., so that the system can improve its own performance. A unit like MYeBOX would make it possible, for example, to monitor and predict faults remotely through applications that recognise seasonal and/or frequency patterns.
So, in some cases they measure multiple variables with minimum sampling and in other cases a single value will be sufficient though it will have to be measured very accurately with maximum sampling.
There are certain aspects, such as security and alarms, that are physically included in the hardware unit (for ex., emergency relays), though they can be controlled through the application.
The architecture defined for this project will be realised in a unit that is the only tool of its kind on the market: applications can be used to generate “à la carte” instruments to interpret real-time data and observe phenomena particular to very diverse fields of engineering.
The result of this project is therefore a measurement system with the following benefits:
Flexibility: as the data collected is processed by the programme rather than by the hardware. This enables it to provide users with information on a wide range of values or combinations/relationships of values for a single set of physical components. The type of architecture defined for this project can process current and stored data in any manner deemed suitable by the user. For example, a power analyzer located in a transformer substation that is linked to various applications can provide the work cycle of the transformer's magnetic circuit for maintenance, or a log of powers, currents and voltages, or can even compare these with reference values to facilitate the detection of overloads, unwanted consumptions, etc. If the same unit is connected to an induction motor, it can provide logs of estimated torque, speed, power and power factor as well as warn of possible defects in the motor or the coupled load.
Low cost: compared to dedicated instruments, due to fierce market competition for computers and mobile devices like smartphones or tablets. Furthermore, these devices can be used for additional tasks associated with the virtual instrument, and can communicate with as many data acquisition units as necessary, though not simultaneously. In comparison, a conventional oscilloscope with storage systems costs around the same as a PC, requires transducers and has very limited functionality.
Portability: the solution runs on tablets or smartphones, units with major processing capacity and a size and weight that make them much more easy to handle than a multimeter.
Safety: once the unit is installed it is not necessary to have it on hand to see the values and the tablet-based user interface is disconnected from the electrical measurements; it is comfortable, lightweight and highly functional.
Wireless communication: using Wi-Fi or wireless communication technology, greatly facilitating access to current data or data stored by the data acquisition unit.
