Chav dej yog qhov tseem ceebqhov chawhauv peb lub neej. Nws tuaj yeem ua tau raws li peb cov kev xav tau ntawm lub cev tab sis muaj qee qhov kev pheej hmoo kev nyab xeeb. Xyoo 2019, ob niam txiv hluas hauv Shanghai tuag tom qab raug tshuaj lom hauv chav dej hauv lawv lub tsev. Lub tuam tsev tua hluav taws tuaj txog ntawm qhov chaw thiab siv lub tshuab kuaj xyuas cov pa tshuaj lom uas nrhiav tau peb txheej hydrogen sulfide tshaj tus qauv. Tom qab nias lub pob ntawm lub tais tso quav, qhov siab tshaj 100ppm hydrogen sulfide tau tsim tam sim. Tom qab kev sim, ob leeg tuag ntawm hydrogen sulfide lom. Raws li cov ntaub ntawv, thaum huab cua muaj 200ppm hydrogen sulfide, nws tuaj yeem ua rau lom yog tias nqus tau rau 5 mus rau 8 feeb. Yog tias huab cua muaj 1000ppm txog 1500ppm, nws tuaj yeem ua rau tuag sai sai. Cov tshuaj lom neeg mob hnyav heev yog: nqus tau 1 mus rau 2 lub qhov ncauj kom tsis txhob ua pa tam sim, tuag tam sim ntawd.
Ntxiv nrog rau qhov kev phom sij zais ntawm cov chav dej hauv tsev, cov chav dej pej xeem kuj yog "cov neeg tua tsis pom". Hauv Kaus Lim Qab Teb, ib tug hluas nkauj tau mus rau hauv chav dej ntawm txoj kev, tab sis tsis tuaj tom qab. Thaum pom nws, nws tsis nco qab thiab tuag tom qab tsev kho mob. Tom qab kev tshawb nrhiav, hydrogen sulfide nyob rau hauv lub tank tso dej ntawm cov pej xeem chav dej tau nqus los ntawm tus ntxhais, uas ua rau tuag. Hydrogen sulfide yog xim tsis muaj xim, muaj kuab lom heev, acidic gas. Nws muaj qhov tshwj xeeb tsis hnov tsw ntawm cov qe lwj, txawm tias qhov qis ntawm hydrogen sulfide tuaj yeem ua rau tib neeg tsis hnov tsw tsw. Qhov peb hu ua "tshuaj tsw qab" yog qhov tshwm sim ntawm kev ua ntawm cov roj sib xyaw ua ke. Cov pa roj kuj muaj cov hydrocarbons xws li methane, uas ua rau muaj kev phom sij heev.
Nrog rau kev txhim kho thev naus laus zis xws li kev txawj ntse txawj ntse thiab Internet ntawm Yam, cov khoom siv thev naus laus zis ntawm cov chav dej ntse ntse tau txuas ntxiv. Nws muab cov ntaub ntawv loj, Is Taws Nem ntawm Yam, huab cia, huab xam, sensors, SIG-MESH thiab lwm yam thev naus laus zis los ua kom cov chav dej ib txwm muaj kom muaj kev nkag siab ntawm lub sijhawm tiag tiag, kev txiav txim siab raug thiab muaj peev xwm ua tiav. Ammonia, hydrogen sulfide, CO2, qhov kub thiab txias, thiab cov av noo yog cov ntaub ntawv tseem ceeb hauv kev ntsuas huab cua hauv chav dej pej xeem. Kev ntsuam xyuas ntawm cov ntaub ntawv no yog sib cais los ntawm peb qhov ntsuas sensor. Txawm tias qee qhov chaw tso quav tso rau pej xeem yuav tsum tau teeb tsa: ammonia roj tswb tswb, hydrogen sulfide tswb thiab tso cua tshuab, thiab lwm yam., kom tshem tawm cov ntxhiab tsw phem hauv lub sijhawm kom tsis txhob muaj teeb meem.
