Software them nyiaj algorithms feem ntau yog siv los siv txoj hauv kev xws li saib -cov ntxhuav, polynomial haum, interpolation, thiab adaptive algorithms (xws li neural networks, Kalman filters). Ntawm cov no, kev sib xyaw ua ke ntawm "saib-cov ntxhuav ntxiv rau kev sib cuam tshuam" sawv cev rau cov ntsiab lus tseem ceeb tshaj plaws hauv kev lag luam.
I. Kev piav qhia ntxaws txog cov txheej txheem kev nqis tes ua tseem ceeb
1. Saib-Table (LUT) Txoj Kev
Lub hauv paus ntsiab lus: Lub sensor qhov tso zis yuam kev yog ntsuas ua ntej ntawm ntau qhov kub thiab txias raws li cov txheej txheem, thiab cov nqi sib raug zoo raug muab khaws cia rau hauv ib qho array lossis rooj.
Cov Txheej Txheem Ua Haujlwm: Thaum lub sijhawm ua haujlwm, lub kaw lus khaws cov txiaj ntsig sib raug raws li qhov ntsuas qhov ntsuas kub thiab ncaj qha kho cov zis.
Qhov zoo: Yooj yim rau siv, lub sijhawm teb ceev, thiab tsim nyog rau cov peev txheej - txwv tsis pub siv xws li microcontrollers.
Disadvantages: siab nco hneev taw; qhov tseem ceeb rau cov ntsiab lus tsis tau sau meej meej yuav tsum tau kwv yees.
Kev Xyaum Ua Lag Luam: Thermocouple txias-cov kev them nyiaj sib txuas feem ntau ua haujlwm ua tiav-hauv Pt100 saib- cov ntaub ntawv rooj, tso cai rau lawv tuaj yeem ua raws li cov qauv siv cov lus teev tseg hauv IEC 60584.
2. Polynomial Fitting Method
Lub hauv paus ntsiab lus: txoj kev ua lej-xws li txoj kev squares tsawg tshaj plaws- yog siv los ua kom haum rau qhov kev sib raug zoo ntawm qhov tsis sib xws rau hauv ntau lub npe.
Qhov zoo: siab raug; muaj peev xwm piav qhia txog cov nonlinearities nyuaj; tsis nco qab hneev taw.
Disadvantages: Siab - txiav txim xam yuam kev tseem ceeb ntawm processor kev ua tau zoo.
Daim ntawv thov Case: Ntse siab sensors siv 5th - xaj polynomial rau tib lub sijhawm them nyiaj rau ob qho tib si nonlinearity thiab kub drift.
3. Txoj Kev Sib Tham Tawm Kab (feem ntau ua ke nrog saib-Tsev Tshab)
Lub hauv paus ntsiab lus: Kev tsim kho raws li qhov zoo li- cov txheej txheem txheej txheem, linear interpolation yog ua los ntawm ob lub ntsiab lus them nyiaj paub los txhim kho qhov tseeb rau cov ntsiab lus nruab nrab.
Cov kauj ruam ua haujlwm:
Qhia qhov ntsuas kub tam sim no ...
Qhov zoo: Txhim kho qhov tseeb ntawm qhov zoo -txoj kev ntawm lub rooj yam tsis muaj kev xav tau ntau ntxiv.
Disadvantages: Cov teeb meem seem tseem yuav tshwm sim rau cov lus teb uas tsis yog kab uas hloov pauv sai.
Qhov Zoo Tshaj Plaws: Qhov "Saib-Up Table + Linear Interpolation" kev sib xyaw ua ke yog qhov kev siv dav tshaj plaws hauv kev ntsuas kev lag luam thiab kev tswj hwm.
