Raws li peb txhua tus paub, muaj kev phom sij thiab teeb meem sib txuas ua ke roj hauv cov mutters, H2S, thiab cov pa roj oxygen uas ua rau muaj kev phom sij rau tib neeg lub cev.
Ua ntej tshaj plaws, xav tias muaj methane, cov nkev tawg hauv thee, muaj cov pov thawj roj hluav taws xob, nrog rau theem kev tiv thaiv kab mob ntawm Illproof thiab av. Cov kev cuam tshuam los tiv thaiv kev yuav tsum muaj zog.
1. Methane:
Methane yog cov roj uas feem ntau hauv cov mines thee. Nws yog cov roj cua thiab tawg. Thaum methane yog tov nrog huab cua, nws yog ib qho yooj yim los ua rau tawg thaum nws ntsib hluav taws. Cov kev tawg txwv ntawm methane yog 5% rau 15% vol, thiab nws qis tawg qhov tsis txwv yog 5% vol, uas 100% lel. Cov kev tawg txwv yog 4.9% mus rau 16% (tsis muaj kev sib txuas hauv qab qhov qis dua, nyob ntsiag to kev tawg saum toj no) thiab cov kev tawg tag nrho yog li 9.5%. Yog li ntawd, roj methane concentration ntawm lub ntes yog qhov tseem ceeb heev. Cov ntsuas hluav taws xob txuas ntxiv tsim los ntawm peb lub tuam txhab muaj cov teeb meem hluav taws xob, siv cov roj av sib txuas, xws li kiv cua, suab solenoid, solenoid li qub. Thaum lub tswb teeb liab tau xa, cov ntxuam tso tawm yog muab rau pib solenoid valve. Nyob rau tib lub sijhawm, cov pa hluav taws xob tau kuaj tau 24 teev nyob rau ib hnub, thiab nws txhawb {{14} modbus raws cov cim thiab cov ntaub ntawv hauv lub sijhawm tiag tiag, uas yooj yim rau kev kuaj pom.
2. Cov pa roj carbon monoxide:
CO feem ntau yog tsim los ntawm qhov tsis tiav ntawm cov dej sib tshooj thee, lossis cov khoom siv pa pa pov tseg.
Lub coulcess concentration siv tshuab hluav taws xob electrochemical. Kev kuaj xyuas ntau ntawm cov ntsuas ruaj ruaj roj hluav taws xob yog 0-1000 ppm. Thaum 50 / 150PPM, lub teeb liab tswb yuav raug xa mus, thiab lub tswb muaj nqi raug muab kho raws li cov neeg siv xav tau. Txhawb cov chaw taws teeb tswj kom teev cov khoom tsis muaj cuab yeej thiab ua qhov ntsuas hluav taws xob.
3.h2s roj
H2s roj kuj tau tsim los ntawm kev ua haujlwm tsis tiav ntawm cov thee. Kev tshawb xyuas ntau ntawm H2S roj ntes yog 0-200 pam, thiab lub teeb liab tswb xa mus nyob rau 10/3ppm.
4.O2:
Coal cov mines nyob hauv ib puag ncig sab hauv av, thiab muaj kev pheej hmoo ntawm cov pa oxygen ensriching lossis hypoxia. Yog li ntawd, tsau cov pa oxygen tuaj yeem ntes cov pa oxygen hauv huab cua 24 teev ib hnub. Thaum cov pa oxygen yog tsawg dua 19.5% vol thiab ntau dua xyoo 23.5%, lub teeb meem tswb yuav raug xa mus kom tsis txhob muaj kev pheej hmoo ntawm cov neeg ua haujlwm tsis txaus.
5. Tsis tas li ntawd, yuav muaj qee cov khoom sib txuas, xws li CO2, tsis tau ua ke thiab tsim cov kev pheej hmoo ntawm hypoxia. Yog li ntawd, tsau cat2 detors kuj xav tau kev kuaj pom. CO2 detectors feem ntau siv cov sensorsed infrared.
6. Cov thee ntawm lub mine ib puag ncig yog qhov kub thiab txias thiab tsis muaj av noo, yog li lub tshuab hluav taws xob tau xav tau muaj zog tiv thaiv kev cuam tshuam. Kuj tseem muaj qee qhov chaw uas xav tau Fandheld portable roj detectors kom nqa nrog koj, xws li muaj roj teeb plaub, uas yuav tsum tau nruab nrog roj teeb rov qab lossis hloov roj teeb. Nws yog qhov zoo tshaj yog tias muaj cov ntaub ntawv tiag tiag cov ntaub ntawv khaws tseg.
Cov qauv siv roj ruaj ruaj tuaj yeem kis tau rau hauv av soj ntsuam vaj huam sib luag, xws li 4G, Lora, thiab sab nraum zoov cov haujlwm tseem tuaj yeem pom cov ntaub ntawv kev hloov thaum txhua lub sijhawm.
Peb lub tuam txhab ua cov tshuaj lom thiab cov tshuaj lom neeg uas muaj kuab lom thiab cov teeb meem roj teeb thiab cov pa hluav taws xob kom pom kev xav tau, txais tos kom sab laj
