Inkqubo yokufumana ubushushu be-BMS kunye nendlela yokulinganisa ngokusekelwe kwinzwa yobushushu be-NTC

Itekhnoloji yelungelo elilodwa lomenzi wechiza inxulumene nommandla wokufumana ubushushu bebhetri kwizithuthi zombane, ngakumbi kwinkqubo yokufumana ubushushu be-BMS esekwe kwinzwa yobushushu be-NTC kunye nendlela yokulinganisa.

Okwangoku, iisensi zeqondo lokushisa zisetyenziswa ngokubanzi kwintsimi yamandla amatsha, ngakumbi inkqubo yokulawula ibhetri yezithuthi zamandla amatsha, oko kukuthi, i-BMS. Okwangoku, i-detector yeqondo lokushisa elichasayo (RTD) kunye ne-thermocouple edibeneyo kunye neesekethe zokulinganisa ezihambelanayo zihlala zisetyenziselwa ukuqokelela ubushushu. Iisekethe zesampulu zobushushu zibandakanya indlela yokwahlula amandla ombane wokuxhathisa kunye nendlela yokuvuselela umthombo wangoku. Nangona kunjalo, ezi ndlela zingasentla zineziphene ezilandelayo: 1. I-RTD yokufumana umqondiso we-analog kunye nesekethe yokucubungula iyinkimbinkimbi kwaye ixabiso liphezulu. Amandla afunekayo ukuze inzwa inikwe amandla iya kuzisa ukunyuka kweqondo lokushisa kwangaphakathi kunye nokwandisa impazamo yokulinganisa ubushushu. Ngexesha elifanayo, iindleko zale skimu ziphezulu, kwaye umthamo wesiphaluka weyunithi yokufumana ukhulu, ongenakuncedo kwi-miniaturization. 2. Ngenxa yobuthathaka obuphantsi be-thermocouple, kuyimfuneko ukukhulisa isignali eqokelelweyo kunye ne-low offset amplifier. Ukongezelela, umgca weqondo lokushisa we-thermocouple uhluphekile, ngoko ke kuyimfuneko ukuhlawulela isiphaluka, okwandisa impazamo yesampuli kunye nokunciphisa ukuchaneka kwesampuli. 3. Okwangoku, indlela ye-thermistor edibeneyo kunye ne-resistance voltage division ixhaphake kakhulu. Esona sizathu siphambili sokwamkelwa kwesi sikimu kukuba izitayile ze-thermistor ziyahluka kwaye ixabiso liphantsi. Nangona kunjalo, ukuchaneka kokufunyanwa kwe-thermistor kuphantsi; Ukushwankathela, kunzima ukudinga iskimu sokufumana ubushushu obuchanekileyo kunye nexabiso eliphantsi. Ijolise kwiintsilelo zeskimu sokufumana ubushushu obukhoyo, eli phepha libeka phambili ukuchaneka okuphezulu kunye nexabiso eliphantsi kwendlela yokufumana ubushushu, efanelekileyo kwiinkqubo ezintsha zokulawula ibhetri yamandla kunye nezinye iinkalo.
