Iindlela zoMlinganiso weZidibaniso zeCable ezahlukeneyo

Iindlela zokulinganisa ezahlukeneyoiintambo zentambo
1. Uhlobo lwekhebula lokubona iqondo lobushushu Umlinganiselo wobushushu: Intambo yokuva iqondo lobushushu ibekwe ngokuhambelana nentambo. Xa ubushushu bekhebula budlula ixabiso leqondo lokushisa elimiselweyo, ikhebula lokuva lifutshane-lijikeleza kwaye i-alarm signal ithunyelwa kwinkqubo yokulawula. Izinto ezingeloncedo kwiintambo zokuvavanya ubushushu eziqhelekileyo zezi: i-alam eyonakalisayo, ubushushu be-alam obusisigxina, umqondiso wempazamo ongaphelelanga, ukufakwa kwenkqubo engafanelekanga kunye nokugcinwa, kunye nezixhobo zonakaliswe ngokulula.
2. Ukulinganisa ubushushu bohlobo lwe-Thermistor: I-Thermistor ingasetyenziselwa ukulinganisa iqondo lokushisa kwentambo, kodwa yimveliso ye-analog. Kufuneka ikhuliswe ngumqondiso, kwaye i-A/D iguqulwe ukuze ifumane. I-thermistor nganye idinga ukuba ifakwe ngabanye, i-wiring inzima, kwaye i-thermistor ilula. Ubungakanani bomonakalo kunye nokugcinwa kukhulu, kwaye inzwa ayinayo umsebenzi wokuzihlola kwaye kufuneka ihlolwe rhoqo.
3. Umlinganiselo weqondo lobushushu boluvo lwe-infrared: isivamvo se-infrared sisebenzisa zonke izinto ezinobushushu obuphezulu kuno-zero ngokupheleleyo ukukhupha amandla emitha ye-infrared kwindawo engqongileyo. Amandla emitha ye-infrared yento kunye nokuhanjiswa kwayo ngokobude be-waveleng kuhambelana ngokusondeleyo nobushushu bomphezulu wayo. Ngoko ke, ngokulinganisa amandla e-infrared aphuma kwinto ngokwayo, ubushushu bomhlaba bunokulinganiswa ngokuchanekileyo.
4. Umlinganiselo wokushisa wohlobo lwe-thermocouple: Isignali yokudlulisa i-thermocouple idinga umgca wembuyekezo okhethekileyo, kwaye umgama wokuhambisa akufanele ube mde kakhulu. Ayifanelekanga imeko yangempela apho intloko yekhebula inomhlaba obanzi wokusabalalisa; i-thermistor idla ngokuxhathisa iplatinam, efuna ngokubanzi ukuhanjiswa kweentambo ezintathu kunye nokuphuma kwebhulorho elinganayo. Umgama wothumelo akufanele ube mde kakhulu, kwaye amandla okuchasana nokuphazamiseka akubi.
5. Umlinganiselo wobushushu bohlobo lwesekethe edibeneyo: Kukho iintlobo ezininzi zezinto zokulinganisa ubushushu bohlobo lwesekethe edibeneyo, phakathi kwayo into ekhoyo yohlobo lwemveliso inokumelana okukhulu kwangaphakathi kwaye ilungele ukuhanjiswa komgama omde. Ngokuqhelekileyo, zincinci ngobukhulu kwaye zinokutywinwa kwindawo yokulinganisa nge-resin ye-silicone ye-thermal conductive, ekwazi ukumelana ne-corrosion, umswakama kunye nokushisa okuphezulu. Iingcingo zangaphandle zikhokelwa ziingcingo ezimbini zokuhambisa idatha, kodwa zichaphazeleka kakhulu ngamandla ombane kwindawo yokulinganisa.
6. Ifayibha ye-Optical isasazwe ukujonga ubushushu: I-fiber optical isasazwe inkqubo yokulinganisa ubushushu yinkqubo ephezulu kakhulu. Umlinganiselo weqondo lobushushu ugqitywe ngokuvelisa i-reverse Raman yokuchithachitha iqondo lobushushu be-laser pulse esasazwe kwifiber optical. Inkqubo yamva nje yokujongwa kwefiber optical fiber ivumela ubude befiber loop ukuya kuthi ga kwi-12 km kunye nokuchaneka komlinganiselo we-±1°C.
