Real-Time Ana­lys­is Soft­ware

Data gen­er­a­tion via IfTA Sig­nalMin­er

The DSP (Di­git­al Sig­nal Pro­cessor) forms the core of every IfTA sys­tem - this is where the real-time ana­lys­is soft­ware IfTA Sig­nalMin­er runs - it is the firm­ware of the DSP (Di­gitale Sig­nal Prozessor)  Here, dy­nam­ic raw data are seam­lessly provided with pre­cise time stamps, pro­cessed, ana­lyzed, new char­ac­ter­ist­ic val­ues formed and mon­itored.This en­sures the real-time ana­lys­is of the data as well as a guar­an­teed re­sponse time and sta­bil­ity as re­quired in pro­tec­tion sys­tems. In con­trast to a PC, there is no op­er­at­ing sys­tem that could in­ter­fere when the user starts pro­grams, other pro­cesses or up­dates.

The com­mu­nic­a­tion with the data cen­ter, the so-called IfTA DataHub  takes place via Eth­er­net. This is where the IfTA Sig­nalMin­er re­ceives its con­fig­ur­a­tion, syn­chron­izes its time and sends the raw data, ana­lys­is res­ults and status in­form­a­tion back to the IfTA DataHub for stor­age and on­line visu­al­iz­a­tion with  IfTA TrendView­er. After a power fail­ure, the DSP starts autonom­ously with the firm­ware and con­fig­ur­a­tion last stored in its flash memory and re­sumes its work after a few seconds.

What Does Real-Time Ana­lys­is Ac­tu­ally Mean?

Real-time ana­lys­is means that between a sig­nal at the sensor and the trig­ger­ing of an ac­tion there is a re­li­able and spe­cif­ic time span - usu­ally in mil­li­second range. Ideally, this time span should be as short as pos­sible in order to have the longest pos­sible re­ac­tion time. Data is pro­cessed im­me­di­ately after gen­er­a­tion. In­stead of the term real-time ana­lys­is, terms such as real-time data ana­lys­is, real-time data in­teg­ra­tion or real-time in­tel­li­gence are often used as syn­onyms. Real-time ana­lys­is is es­sen­tial for a pro­tec­tion sys­tem that re­quires fast re­sponse times.

Char­ac­ter­ist­ic Val­ues Cal­cu­lated in Real-Time

The IfTA Sig­nalMin­er is able to cal­cu­late and mon­it­or the fol­low­ing char­ac­ter­ist­ic val­ues per chan­nel and for groups of chan­nels in real-time:

These ana­lyses are car­ried out con­tinu­ously and syn­chron­ously on all time val­ues. The user can freely para­met­er­ize on which chan­nel of an out­put mod­ule a cal­cu­lated char­ac­ter­ist­ic value is is­sued.  Lim­its and other para­met­ers (fre­quency band lim­its, av­er­aging factors, dis­turbed chan­nels, etc.) can be defined dur­ing runtime via input mod­ules without re­con­fig­ur­a­tion.

Data Ac­quis­i­tion and Ana­lys­is: The Basis for In­dustry 4.0

The ac­quis­i­tion of data and the cor­res­pond­ing ana­lys­is form the basis for In­dustry 4.0. The data that is re­quired de­pends on the spe­cif­ic ap­plic­a­tion, but the ob­ject­ive re­mains the same: to col­lect as much valu­able in­form­a­tion as pos­sible and eval­u­ate it mean­ing­fully in order to im­ple­ment im­prove­ments in the pro­cess.
