The Pro­ces­sor for Real-Time Anal­y­sis

Stable and re­li­able data pro­cess­ing is the basis/foun­da­tion of the IFTA plat­form's suc­cess. A dig­i­tal sig­nal pro­ces­sor (DSP) pro­cess­es high-res­o­lu­tion vi­bra­tion data in real-time with the IFTA Sig­nalMin­er firmware using the so-called Fast Fouri­er Trans­for­ma­tion (FFT). This level in the IFTA sys­tem does not re­quire an op­er­at­ing sys­tem and there­fore guar­an­tees 24/7 pro­tec­tion and op­er­a­tion. After a power fail­ure, the DSP starts au­tonomous­ly using the firmware and con­fig­u­ra­tion last stored in its flash mem­o­ry and re­sumes its work after a few sec­onds.

Real-Time Ca­pa­bil­i­ty for High Plant Avail­abil­i­ty

The IFTA sys­tems are based on a dig­i­tal sig­nal pro­ces­sor for sig­nal anal­y­sis. This al­lows the de­ter­min­is­tic run­time of com­mands nec­es­sary for pro­tec­tion sys­tems with real-time ca­pa­bil­i­ty in in­dus­tri­al en­vi­ron­ments. The ca­pa­bil­i­ty for real-time pro­cess­ing is es­pe­cial­ly im­por­tant in pro­tec­tion as it pro­vides high avail­abil­i­ty of ma­chines or plants. Op­ti­mized al­go­rithms en­sure short anal­y­sis times. Spec­tra with up to 6400 lines cal­cu­lat­ed live per chan­nel are the most im­por­tant ex­am­ple for this. The eval­u­a­tion soft­ware IFTA TrendView­er can di­rect­ly vi­su­al­ize data pre-cal­cu­lat­ed by the DSP.

The IFTA sys­tems base on a sig­nal pro­ces­sor for sig­nal anal­y­sis - the IFTA DSP. By means of the firmware IFTA Sig­nalMin­er it pro­vides real-time pro­cess­ing of input sig­nals and out­put of anal­y­sis re­sults. The ca­pa­bil­i­ty for real-time is in par­tic­u­lar re­quired when pro­tect­ing in­dus­tri­al plants, as it en­sures fast pro­cess­ing of sig­nals and high avail­abil­i­ty. For data stor­age and changes in con­fig­u­ra­tion the DSP com­mu­ni­cates via net­work with the IFTA DataHub on an IFTA pan­elPC, IFTA SlotPC or a work­sta­tion.

High­lights

  • Real-time data anal­y­sis and pro­tec­tion
  • Stand-alone op­er­a­tion - pro­tec­tion func­tions are fully func­tion­al even with­out PC since con­fig­u­ra­tion and firmware are lo­cat­ed on a flash stor­age and con­se­quent­ly the mod­ule starts with­out a PC
  • PC in­de­pen­dent time stamp­ing of data - by means of its own clock all ac­quired sig­nals are signed with a pre­cise time stamp. For track­ing the DSP syn­chro­nizes its clock with the PC
  • 6 Sta­tus LEDs to dis­play mes­sages
  • The op­er­at­ing tem­per­a­ture of all mod­ules is record­ed in a SPU
  • Micro USB port for main­te­nance rea­sons (firmware up­grades und log­ging)

Ap­pli­ca­tion ex­am­ples

  • Mea­sure­ment of tor­sion­al vi­bra­tions in drive trains, gas tur­bines, steam tur­bines, power gen­er­a­tors
  • A ro­tat­ing shaft is equipped with 100 stripes around the cir­cum­fer­ence by means of ze­brat­ape. The LMM2 de­ter­mines in a flash which stripe is in front of the sen­sor head. The ana­log out­put sig­nal is fur­ther pro­cessed by the IFTA AT2 High Speed Timers and the IFTA DSP. In this way, not only the ro­ta­tion­al speed and ro­ta­tion­al ve­loc­i­ty are de­ter­mined, but also the tor­sion­al vi­bra­tions up to the 50th order. In that way, for ex­am­ple, a tor­sion­al vi­bra­tion can be de­ter­mined with­out hav­ing to equip the rotor with a ro­tary en­coder.
