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.
