1. Isetyenziselwa ukujonga igesi evuthayo kunye ne-alamu
Okwangoku, ukuphuhliswa kwezinto ezithintekayo zegesi zenze i-gas sensors kunye novelwano oluphezulu, ukusebenza okuzinzile, isakhiwo esilula, ubungakanani obuncinci, kunye nexabiso eliphantsi, kwaye kuphuculwe ukhetho kunye novelwano lwenzwa.Iialamu zerhasi ezikhoyo ikakhulu zisebenzisa i-tin oxide kunye nezinzwa zegesi ezixabisekileyo zentsimbi, kodwa ukukhetha kubi, kwaye ukuchaneka kwe-alamu kuchaphazeleka ngenxa yetyhefu ye-catalyst.Uvakalelo lwezixhobo ze-semiconductor ze-gas-sensitive kwi-gas zihambelana nobushushu.Uvakalelo lusezantsi kwiqondo lobushushu begumbi.Njengoko iqondo lokushisa likhuphuka, uvakalelo luyanda, lufikelela phezulu kwiqondo lokushisa elithile.Ekubeni ezi zixhobo ze-gas-sensitive zifuna ukufezekisa uvakalelo olungcono kumaqondo aphezulu (ngokubanzi ngaphezu kwe-100 ° C), oku akudli nje amandla okufudumala okongeziweyo, kodwa kunokubangela nomlilo.
Ukuphuhliswa kwezinzwa zegesi kuye kwasombulula le ngxaki.Ngokomzekelo, inzwa yegesi eyenziwe nge-iron oxide-based gas-sensitive ceramics inokudala inzwa yegesi enovakalelo oluphezulu, ukuzinza okulungileyo, kunye nokukhetha okuthile ngaphandle kokongeza i-catalyst yensimbi ehloniphekileyo.Ukunciphisa ukushisa okusebenzayo kwezixhobo ze-semiconductor ze-gas-sensitive, ziphucule kakhulu uvakalelo lwabo kwiqondo lokushisa, ukwenzela ukuba basebenze kwiqondo lokushisa.Okwangoku, ukongeza kwiisamics zeoksidi zesinyithi ezisetyenziswa ngokuqhelekileyo, ezinye iikeramics zegesi edibeneyo ye-oxide semiconductor yegesi exubeneyo kunye neeseramics zegesi ye-oxide exutyiweyo ziye zaphuhliswa.
Faka i-sensor yegesi kwiindawo apho iigesi ezinokutsha, eziqhumayo, ezinetyhefu kunye neziyingozi ziveliswa, zigcinwe, zithuthwe, kwaye zisetyenziselwa ukufumanisa umxholo wegesi ngexesha kwaye ufumane iingozi zokuvuza kwangoko.I-sensor yegesi idibaniswe nenkqubo yokukhusela, ukwenzela ukuba inkqubo yokukhusela isebenze ngaphambi kokuba igesi ifike kumda wokuqhuma, kwaye ukulahleka kwengozi kuya kugcinwa kuncinci.Ngelo xesha, i-miniaturization kunye nokunciphisa ixabiso leenzwa zegesi kwenza kube lula ukungena ekhaya.
2. Ukusetyenziswa ekubhaqweni kwegesi kunye nokuphathwa kwengozi
2.1 Ukufunyanwa kweentlobo zegesi kunye neempawu
Emva kokuba kwenzeke ingozi yokuvuza kwegesi, ukuphathwa kwengozi kuya kugxininisa kwisampuli kunye nokuvavanya, ukuchonga iindawo ezilumkisayo, ukulungelelanisa ukufuduswa kwabantu kwiindawo ezinobungozi, ukuhlangula abantu abanetyhefu, ukuplagi kunye nokucoca, njl njl. ukunciphisa umonakalo kubasebenzi obangelwa ukuvuza, okufuna ukuqonda ubutyhefu begesi evuzayo.Ubuthi begesi bubhekisa ekuvuzeni kwezinto ezinokuphazamisa ukusabela okuqhelekileyo kwemizimba yabantu, ngaloo ndlela kuncitshiswe ukukwazi kwabantu ukwenza iindlela zokuchasa kunye nokunciphisa ukulimala kwiingozi.Umbutho woKhuseleko loMlilo weSizwe wahlula ubutyhefu bezinto kwezi ndidi zilandelayo:
N\H=0 Kwimeko yomlilo, ngaphandle kwezinto ezinokutsha ngokubanzi, azikho ezinye izinto eziyingozi ekutyhilekeni kwexesha elifutshane;
N\H=1 Izinto ezinokubangela ukucaphuka kwaye zibangele umonzakalo omncinci ekutyhilekeni kwexesha elifutshane;
N\H=2 Uxinzelelo oluphezulu okanye ukuba sesichengeni sexeshana elifutshane kunokubangela ukukhubazeka okwexeshana okanye ukwenzakala okushiyekileyo;
N\H=3 Ukutyhileka okwethutyana kunokubangela ukwenzakala okwethutyana okanye okushiyekileyo;
N\H=4 Uvelwano lwexeshana elifutshane lunokubangela ukufa okanye ukwenzakala okumandundu.
Qaphela: Ixabiso le-toxicity coefficient ye-N\H engentla isetyenziselwa ukubonisa iqondo lomonakalo womntu, kwaye ayinakusetyenziselwa ucoceko lwemizi-mveliso kunye novavanyo lokusingqongileyo.
Ekubeni igesi enetyhefu ingangena emzimbeni womntu ngokusebenzisa inkqubo yokuphefumula komntu kwaye ibangele ukulimala, ukukhuselwa kokhuseleko kufuneka kugqitywe ngokukhawuleza xa ujongene neengozi zegesi ezinobungozi.Oku kufuna ukuba abasebenzi bokuphatha ingozi baqonde uhlobo, ubuthi kunye nezinye iimpawu zerhasi ngexesha elifutshane emva kokufika kwindawo yengozi.
Hlanganisa i-gas sensor array kunye neteknoloji yekhompyutheni ukwenza inkqubo yokukhangela igesi ehlakaniphile, enokuchonga ngokukhawuleza nangokuchanekileyo uhlobo lwegesi, ngaloo ndlela ibona ubuthi begesi.Inkqubo yokuqonda igesi ehlakaniphile iqulunqwe yi-gas sensor array, i-signal processing system kunye nenkqubo yokuphuma.Ubuninzi bezinzwa zerhasi ezineempawu zovakalelo ezahlukeneyo zisetyenziselwa ukwenza uluhlu, kwaye iteknoloji yokuqaphela ipateni ye-neural network isetyenziselwa ukuqatshelwa kwegesi kunye nokujongwa koxinzelelo lwerhasi exutyiweyo.Kwangaxeshanye, uhlobo, ubume, kunye netyhefu eqhelekileyo eyityhefu, eyingozi, kunye neegesi ezivuthayo zifakwa kwikhompyuter, kunye nezicwangciso zokuphatha ingozi ziqulunqwe ngokwesimo segesi kunye negalelo kwikhompyuter.Xa kusenzeka ingozi yokuvuza, inkqubo yokukhangela igesi ekrelekrele iya kusebenza ngokwezi nkqubo zilandelayo:
Ngenisa indawo→isampulu yerhasi yeadsorb→isivamvo serhasi yokuvelisa umqondiso→uphawu lwekhompyutha →udidi lwegesi oluphuma kwikhompyutha, indalo, ubutyhefu kunye nesicwangciso sokulahlwa.
Ngenxa yovakalelo oluphezulu lwenzwa yegesi, inokubonwa xa i-gas concentration iphantsi kakhulu, ngaphandle kokungena nzulu kwindawo yengozi, ukwenzela ukuba ugweme umonakalo ongeyomfuneko obangelwa ukungazi kakuhle imeko.Ukusebenzisa inkqubo yekhompyutha, le nkqubo ingentla ingagqitywa ngokukhawuleza.Ngale ndlela, amanyathelo okukhusela asebenzayo anokuthathwa ngokukhawuleza nangokuchanekileyo, isicwangciso esichanekileyo sokulahla sinokuphunyezwa, kwaye ilahleko yengozi ingancitshiswa ibe yincinci.Ukongezelela, ngenxa yokuba inkqubo igcina ulwazi malunga nohlobo lweegesi eziqhelekileyo kunye nezicwangciso zokulahla, ukuba uyayazi uhlobo lwegesi ekuvuzeni, unokubuza ngokuthe ngqo uhlobo lwegesi kunye nesicwangciso sokulahla kule nkqubo.
2.2 Fumana iindawo ezivuzayo
Xa kwenzeka ingozi yokuvuza, kuyimfuneko ukufumana ngokukhawuleza indawo yokuvuza kwaye uthathe amanyathelo afanelekileyo okuplaga ukukhusela ingozi ekuqhubeni ukwandisa.Kwezinye iimeko, kunzima kakhulu ukufumana iindawo ezivuzayo ngenxa yemibhobho emide, izikhongozeli ezininzi, kunye nokuvuza okufihlakeleyo, ngakumbi xa ukuvuza kukhanya.Ngenxa yokuphazamiseka kwegesi, emva kokuvuza kwerhasi kwisikhongozeli okanye umbhobho, phantsi kwentshukumo yomoya wangaphandle kunye nethambeka langaphakathi loxinaniso, iqala ukusasazeka, oko kukuthi, ngokusondeleyo kwindawo yokuvuza, kokukhona iqondo legesi liphezulu.Ngokwale nqaku, ukusetyenziswa kwe-smart gas sensors kunokusombulula le ngxaki.Ngokwahlukileyo kwinkqubo yoluvo olukrelekrele olubona uhlobo lwerhasi, uluhlu lwesivamvo segesi lwale nkqubo luqulunqwe liqela labenzi boluvo begesi abanovakalelo oludlulanayo, ukuze ubuntununtunu benkqubo yoluvo kwirhasi ethile buphuculwe, kwaye ikhompyuter isetyenziselwa lungisa irhasi.Utshintsho lwesignali yento ebuthathaka inokubona ngokukhawuleza utshintsho lwegesi, kwaye emva koko ufumane indawo yokuvuza ngokwenguqu yoxinzelelo lwegesi.
Okwangoku, ukudityaniswa kweenzwa zegesi kwenza ukuba i-miniaturization ye-sensor systems inokwenzeka.Umzekelo, i-sensor ye-ultrafine particle edibeneyo ephuhliswe yinkampani yaseJapan ** inokubona i-hydrogen, i-methane kunye nezinye iigesi, ezigxininiswe kwi-2 mm yesikwere se-silicon.Kwangaxeshanye, uphuhliso lobuchwepheshe bekhompyuter lunokwenza isantya sokubona le nkqubo ngokukhawuleza.Ke ngoko, inkqubo yenzwa ehlakaniphile encinci kwaye kulula ukuyiphatha inokuphuhliswa.Ukudibanisa le nkqubo kunye neteknoloji yokuqaphela umfanekiso ofanelekileyo, usebenzisa iteknoloji yokulawula kude ingenza ukuba ingene ngokuzenzekelayo kwiindawo ezifihliweyo, iindawo ezinetyhefu neziyingozi ezingafanelekanga ukuba abantu basebenze, kwaye bafumane indawo yokuvuza.
3. Amagqabantshintshi okuqukumbela
Phuhlisa izinzwa ezintsha zegesi, ngakumbi uphuhliso kunye nophuculo lweenkqubo ezikrelekrele zokuva igesi, ukuze bakwazi ukudlala indima ye-alam, ukufumanisa, ukuchongwa, kunye nokwenza izigqibo ezikrelekrele kwiingozi zokuvuza kwegesi, ukuphucula kakhulu ukusebenza kakuhle kunye nokusebenza kwengozi yokuvuza kwegesi. ukuphatha.Ukhuseleko ludlala indima ebalulekileyo ekulawuleni ilahleko yeengozi.
Ngokuvela ngokuqhubekayo kwezixhobo ezitsha zegesi, i-intelligence ye-gas sensors iye yaphuhliswa ngokukhawuleza.Kukholelwa ukuba kwixesha elizayo elingekude, iinkqubo zokuva igesi ehlakaniphile kunye nobuchwepheshe obukhulileyo ziya kuphuma, kwaye imeko yangoku yokusingatha ingozi yokuvuza kwegesi iya kuphuculwa kakhulu.
