Ukuza kuthi ga kwi-2020.12.5, kukho abantu abayi-122 ababhubhileyo kwimigodi yamalahle kulo lonke ilizwe kulo nyaka, babulala okanye babambisa abantu abangama-224. Kulo nyaka, iingozi ezinkulu zokhuseleko emigodini yamalahle (xa kuthelekiswa nowama-2019) zonyuke ngesinye, kwaye inani labantu ababhubhileyo lonyuke ngabantu abayi-16, lonyuke nge-50% ne-44% ngokulandelelanayo.” Ingozi yomlilo kaChongqing Songzao “9.27” kunye nabantu abangama-38 bonzakele; emazantsi entliziyo yam.
Emva kohlalutyo olusisiseko, isizathu seChongqing Songzao "9.27" yengozi yomlilo yi-Downhole No. 2 idiphu enkulu, Ukugqoka okunzulu kunye nokukrazula kwebhanti yamalahle. Emva kokuba iqondo lokushisa ibhanti liyenyuka. Ngenxa yokungaphumeleli kwesixhobo sokukhusela ukushisa kunye nomtshini womsi ofakwe kwi-conveyor yebhanti, kwakungekho silumkiso okanye ukuyeka ukusebenza kwebhanti. Yabangela ukuba ibhanti livuthe umlilo kwaza kwavutha amalahle ebhanti. Iigesi ezinobuthi neziyingozi eziveliswa kukutsha ziya kuqukuqela zibuyele kwindawo yokusebenza, zibangele ukutyhefeka kwabasebenzi.
Imimiselo yokhuseleko kwimigodi yamalahle ichaza ukuba ukuxinana kwekhabhon monoksayidi emoyeni kwimigodi yamalahle akusayi kudlula i-0.0024%, kwaye i-carbon monoxide iya kuveliswa xa imithungo yamalahle itshiswa ngokuzenzekelayo okanye xa kuvela imililo engaphantsi komhlaba. Sonke siyazi ukuba i-carbon monoxide poisoning iyingozi kakhulu. Emva kokuba i-carbon monoxide ifakwe emzimbeni womntu, iya kudibaniswa ne-hemoglobin emzimbeni womntu, kwaye yenza i-carboxyhemoglobin. Inokwenza i-hemoglobin emzimbeni womntu ilahlekelwe ngumsebenzi kunye nomsebenzi wokuthwala ioksijini, ngoko ke inokubangela i-hypoxia kunye ne-asphyxia. Iingozi ezininzi zemigodi yamalahle zininzi kodwa ukuveliswa okanye ukuvuza kweegesi ezinetyhefu ezifana nekhabhon monoxide kubangele ityhefu yabasebenzi kunye neengozi ezibulalayo. Ngoko ke, ekuhloleni kwethu ukhuseleko lwemihla ngemihla, kufuneka sihlawule ngokukodwa ekusebenzeni okuqhelekileyo kunye nokusebenza kwee-alamu zomsi, i-carbon monoxide alarms kunye nezinye izixhobo zokubonelela ngesiqinisekiso sokhuseleko lokhuseleko lwethu.
I-HENGKO ehleliweyo ye-alamu isixhobo sokubona i-co, inenzuzo yokuphendula ngokukhawuleza, uvakalelo oluphezulu, ikhono elinamandla lokuchasana nokuphazamiseka kunye ne-IP65 yokukhusela ibakala. Xa i-concentration ye-carbon monoxide idlula ixabiso le-preset yesixhobo, i-detector iya kuthumela ngokukhawuleza isignali ye-alamu evakalayo kunye nebonakalayo.
Imodyuli ye-HENGKO CO sensor yimodyuli yegesi yendalo yonke eyenzelwe kwaye yenziwe ngokudibanisa iteknoloji yokufumanisa i-electrochemical kunye nesekethe enzima. Eli candelo lisebenza kunye nesekethe elula yokuqhuba, enemveliso yedijithali kunye ne-analog voltage output, ukuzinza okulungileyo kunye nobomi obude. Isiphumo sokulinganisa sinokufundwa kwi-microprocessor ngokusebenzisa i-interface ye-I2C yomsebenzisi.
Ukongeza kwi-alamu ye-carbon monoxide esisigxina, i-HENGKO nayo ine-aisixhobo esiphathwayo segesi esiphathwayoekwazi ukubona ngokuqhubekayo ukuxinana kwerhasi enye. I-detector ithatha isampuli yepompo ukuze ibone igesi, kwaye umsebenzisi unokukhetha intonga efanelekileyo ngokweemfuno ezahlukeneyo zokusingqongileyo, okwenza umlinganiselo ulungele ngakumbi. Umboniso wamkela isikrini esikhulu se-OLED dot matrix display, ebonisa ngokubonakalayo ukugxila, uluhlu kunye nexesha langoku legesi elinganiswayo. Imowudi elula yamaqhosha amathathu kunye nolwazi oluneenkcukacha olukhawulezayo lwenza umsebenzi ube mfutshane kwaye kulula ukuwuqonda.
