Binciken Dalilai guda uku na rashin aikin firikwensin zafin jiki

Abubuwan da ke haifar da gazawar firikwensin zafin jiki duka biyu ne masu sauƙi kuma masu rikitarwa, kuma dole ne a bincika takamaiman matsaloli. Dangane da fiye da shekaru goma na samarwa da ƙwarewar aiki, cibiyar sadarwar ƙwararrun firikwensin yana ba da bincike mai sauƙi kamar haka.

1. Tabbatar tabbatar da cewa firikwensin zafin jiki ba daidai ba ne. Ga alama shirme ne, a zahiri yana da mahimmanci. Lokacin da masu fasaha da yawa suka fuskanci matsaloli a wurin, koyaushe suna tunanin cewa firikwensin zafin jiki ya karye a farkon lokaci, kuma suna ɗauka cewa firikwensin zafin jiki ne ya karye. Lokacin da aka sami matsala a wurin, abu na farko da ya zo a zuciya shi ne na'urar firikwensin zafin jiki, wanda ke nuna cewa alkibla da kusanci daidai ne. Ma'amala da kowace matsala dole ne ta tafi daga sauƙi zuwa sarƙaƙƙiya, amma a ɗauka cewa ta kasance mai ƙima da son zuciya, wanda bai dace ba don gano matsalar cikin sauri. Yadda za a ƙayyade idan firikwensin zafin jiki ya karye? Abu ne mai sauƙi - bincika abin da kuke tsammani ba shi da kyau, ko kawai maye gurbin shi da sabo.

2. Duba wayoyi. Laifin tsarin ban da na'urori masu auna firikwensin ba su cikin iyakar binciken wannan labarin (ana iya samun su akan Cibiyar Sadarwar Ƙwararrun Sensor). Don haka, don fayyace cewa firikwensin ya yi kuskure, mataki na gaba shine bincika hanyoyin haɗin kai, gami da haɗin haɗin tsakanin firikwensin da kayan aiki, tsarin tarin tarin, firikwensin da firikwensin, da kuma wayoyi na firikwensin kanta. A taƙaice, ya zama dole don ƙayyade da kuma kawar da kurakuran wayoyi da ke haifar da rashin daidaituwa, haɗin kai, gajerun hanyoyi, da wasu dalilai, don rage farashin gyarawa da gyarawa.

3. Ƙayyade nau'in firikwensin zafin jiki. Wannan kuskure ne na gama-gari. Akwai nau'ikan na'urori masu auna zafin jiki da yawa, gami da nau'in juriya, nau'in analog, nau'in dijital, da sauransu. A matsayin mai fasaha, kuna buƙatar sanin yadda ake yanke hukunci da farko. Yin amfani da multimeter don auna juriya na nau'in tsayayya zai iya ƙayyade ingancinsa nan da nan, yanayin zafi mai kyau, mummunan zafin jiki, ƙimar juriya, da dai sauransu; Don nau'ikan analog, zaku iya amfani da oscilloscope don lura da girman girma da yanayin ƙarfin lantarki ko fitarwa na yanzu, sannan ku yanke hukunci; Na'urori masu auna zafin jiki na dijital suna da ɗan wahala saboda yawanci suna da ƙaramin haɗaɗɗiyar da'ira a ciki kuma suna buƙatar sadarwa tare da microcontroller don tantancewa. Kuna iya amfani da microcontroller naku don gwajin mutum ɗaya, ko amfani da na'urar masana'anta ko kayan aikin da aka saba amfani da su don gwaji. Gabaɗaya ba a yarda a auna firikwensin zafin jiki na dijital kai tsaye da na'ura mai ba da hanya tsakanin hanyoyin sadarwa, saboda yawan ƙarfin lantarki ko ƙone "chip" kai tsaye na iya haifar da sabbin kurakuran da'ira, wanda ke sa ba za a iya tantance ainihin musabbabin laifin ba.

Domin tabbatar da aiki na yau da kullun na waɗannan sassa da kayan aiki tare da na'urori masu auna zafin jiki, dole ne mu koyi abubuwan da ke haifar da gazawar firikwensin zafin jiki yayin riƙe waɗannan na'urori.
