The Working Principle Of Tachogenerator

The working principle of the tachogenerator is to convert the rotational speed into a voltage signal. It operates reliably, but it is bulky and has low precision. Since the measured value is analog, it must be read into the computer after A/D conversion. The working principle of the pulse generator is to output a corresponding number of pulse signals each time according to the generator speed. Select or design a pulse generator as required for high performance inspection. The speed measuring device occupies a very important position in the locomotive control system. The requirements for the side speed device are strong resolution, high precision and the shortest possible detection time. The application of Hall sensor is used to measure the magnetic field strength to obtain a stable pulse square wave signal to realize the measurement of locomotive speed.

Princippet for tachogeneratorens drift er at konvertere omdrejningshastigheden til et spændingssignal. Det fungerer pålideligt, men er voluminøst og har lav nøjagtighed. Da den målte værdi er analog, skal den læses ind i computeren efter analog-til-digital konvertering. Funktionsprincippet for pulsgeneratoren er at udsende det tilsvarende antal impulssignaler hver gang i overensstemmelse med generatorens hastighed. Vælg eller design en pulsgenerator for at imødekomme kravene til overvågning med høj ydeevne. En anordning til måling af hastighed indtager et meget vigtigt sted i lokomotivstyringssystemet. Krav til enhed til lateral hastighed: høj opløsning, høj nøjagtighed og minimal detektionstid. Brugen af ​​en Hall-sensor bruges til at måle magnetfeltstyrken for at opnå et stabilt pulseret rektangulært signal til realisering af en lokomotivhastighedsmåling.

Mabda’a hawlgalka tachogenerator waa in loo beddelo xawaaraha wareegga oo loo beddelaa aaladda korantada. Waxay u shaqeysaa si la isku halleyn karo, laakiin weyna weyn tahay isla markaana saxsanaan yar. Maaddaama qiimaha la cabiray ay tahay analog, waa in lagu akhristaa kombiyuutarka ka dib beddelka analog-dijitaalka ah. Mabda’a hawlgalka matoorrada garaaca wadnaha waa in la soo saaro tirada u dhiganta calaamadaha garaaca wadnaha waqti kasta iyadoo la raacayo xawaaraha koronto dhaliyaha. Xullo ama naqshadee dhaliyaha garaaca wadnaha si ay u buuxiso shuruudaha kormeerka waxqabadka sare. Qalabka lagu cabbiro xawaaraha wuxuu ku fadhiyaa meel aad u muhiim ah nidaamka xakamaynta isgaarsiinta. Shuruudaha aaladda xawaaraha dambe: xallinta sare, saxsanaanta sare iyo waqtiga ugu yar ee ogaanshaha. Adeegsiga aaladda Hoteelka waxaa loo isticmaalaa in lagu cabbiro xoogga meeraha magnetic si loo helo calaamad deggan oo kala jiidan oo isjiidjiidsan oo lagu garto cabbiraadda xawaaraha dhaqdhaqaaqa.
