IIoT (Industrial Internet of Things)

Sica has the option of configuring and performing electrical and energy data readings through the Software Each Computing, Industrial Internet of Things (IIoT) that 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 carried out the configuration from the Software, having to make a new version and compilation for each model of analyser, the IIoT allows any model of analyser from any manufacturer with Modbus protocol to be configured from the interface. This allows real-time readings of both Modbus TCP/IP and RTU analysers.

In addition, the units of the data 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 URCs.

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

In the case that an analyser model is obtained that stores data of a certain type in a different way, a new conversion function can be created from the interface, thus residing in the software the basic functions for the conversion of data types of the frames.

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

  • Phase - neutral voltage of the 3 electrical phases
  • Phase-to-phase voltage of the 3 electrical phases
  • Phase - neutral current of the 3 electrical phases
  • Current per neutral
  • Cosine of Phi in the 3 electrical phases
  • Current unbalance
  • Frequency
  • THD phase - neutral voltage of the 3 electrical phases
  • THD voltage phase - phase of the 3 electrical phases
  • THD phase - neutral current of the 3 electrical phases
  • Total active power
  • Total Power Factor

IIoT READING AND ARCHITECTURAL 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 of Siemens, very economic industrial integration board, with which it can be read with perfection by TCP/IP. However, it can be scaled depending on the hardware where it is installed on the client, Nanobox, Microbox...

The IIoT has a loop reading process of analyzers (multimodel and multimanufacturer) 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 reading time of one second.

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 from the maximum, minimum or calculated averages.

In this way the information will be executed more quickly, together with a quality control oriented to the recording of any communication errors, frame reading and incorrect values of the 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 meter/s through the IIoT sending us the reading, avoiding the problem of communications that can be produced.

 

Arquitectura IIoT

 

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

In addition, a GSM/GPRS card is available so that the IIoT can be used as a backup or replacement for the LAN network.

Based on the electrical measurement, Power Quality or Energy Quality analyzers are integrated, classified according to the EN50160 standard, in which variables such as flickers or short or long duration voltage flashes, voltage and current harmonics among others, as well as the generation of events that show voltage drops, overvoltages or voltage interruptions (VSSI events), etc. are integrated.
