IIoT 


INDUSTRIAL INTERNET OF THINGS

Sica has the option of configuring and reading electrical and energy data through the software Edge Computing, Industrial Internet of Things (IIoT) which acquires data from a network of analysers to which it is connected, processing the average, maximum and minimum values and sending this information to the EMS.

Unlike the old URC, which made the configuration from the Software, having to make a new version and compilation for each model of analyzer, the IIoT allows any model of analyzer of any manufacturer with Modbus protocol can be configured from the interface. This allows real time readings of both Modbus TCP/IP and RTU analyzers.

In addition, the data units of the variables of each analyser are also configured from the interface, as well as the variables of the frames, the frames, the Modbus functions, Endianess, the reading protocols, ... avoiding scaling problems displayed in the old URC.

This new Software IIoT performs a homogeneous treatment and storage of variables and values in such a way that they are stored in databases in a logical and structured way and not in mapped files, for better comparisons and groupings of data from different analysers.

In the event that an analyzer model is obtained that stores data differently for a given type of data, a new conversion function can be created from the interface, thus residing in the software the basic functions for converting frame data types.

The Software has a Web App through which the different electrical variables can be visualized in real time, together with their corresponding curves. Among the 26 electrical variables are:

  • Voltage phase - neutral of the 3 electrical phases
  • Voltage phase - phase of the 3 electrical phases
  • Current phase-neutral of the 3 electrical phases
  • Current per neutral
  • Cosine of Phi in the 3 electrical phases
  • Current unbalance
  • Frequency
  • THD voltage phase - neutral of the 3 electrical phases
  • THD voltage phase - phase of the 3 electrical phases
  • THD current phase - neutral of the 3 electrical phases
  • Total Active Power
  • Total Power Factor

 

IIoT READING AND ARCHITECTURE PROCESS

The design of the upgrade of the old URC, is based on the basic hardware where it has been implemented is in the IIoT 2040 Siemens, very economical industrial integration board, with which you can read perfectly by TCP / IP. However, it can be scaled depending on the Hardware where it is installed in the client, Nanobox, Microbox...

The IIoT has a loop reading process of analyzers (multi-model and multi-manufacturer) that have been configured and discharged using BBDD Redis.

This database is executed and resides in the RAM memory, giving the possibility of reading up to 15 - 20 analysers and reading up to 26 electrical variables in real time, with a second reading time.

The electrical variables that we currently read with average values of 30 seconds, are stored in the database and can be represented in real time, in such a way that the processes are shown and the average values are calculated either of the maximum values, minimum values or of the calculated averages.

In this way the information will be executed more quickly, together with a quality control aimed at recording any communication error, frame reading and incorrect values of variables or electrical data.

Our software, in addition, also has integrated the Medcom, giving the possibility of attacking directly to the serial port of the counter/s through the IIoT sending us the reading, avoiding the problem of communications that can be produced.

 

Arquitectura IIoT

 

For those scenarios that allow it this can be connected in place of Modem. The advantage is that it can be managed remotely, and not in physical form as has been done until now, in addition to controlling the conditions of the processor among other advantages.

To this we add the disposition of a GSM/GPRS card, so that the IIoT serves as backup of the LAN or replacement of it.

Starting from the electrical measurement, it integrates Power Quality or Power Quality analyzers, classification according to EN50160, which integrates variables such as flickers or flickers of short or long duration voltage, harmonics of voltage and current among others, as well as the generation of events that show voltage drops, overvoltages or interruptions of voltage (VSSI events), and so on.
