Kodi tingatani kuti tidziteteze tokha pa ngozi za migodi ya malasha zomwe zimachitika pafupipafupi?

Mpaka 2020.12.5, pakhala imfa 122 m'migodi ya malasha mdziko muno chaka chino, zomwe zapha kapena kutsekereza anthu 224. Chaka chino, ngozi zazikulu zachitetezo cha migodi ya malasha (poyerekeza ndi 2019) zawonjezeka ndi munthu mmodzi, ndipo chiwerengero cha imfa chawonjezeka ndi anthu 16, kuwonjezeka kwa 50% ndi 44% motsatana." Ngozi yamoto ya Chongqing Songzao "9.27", anthu 16 afa ndipo anthu 38 avulala; Ngozi yamoto ya Chongqing Songzao "9.27" yachititsa imfa 23. Miyoyo yambiri yatsopano yayimitsidwa pansi pa mgodi wa malasha. Ngakhale tikudandaula, chitetezo cha ntchito ya mgodi wa malasha chiyeneranso kudzutsa chidwi cha anthu ndikuliza belu lochenjeza pansi pa mtima wanga.

Pambuyo pa kusanthula koyambira, chifukwa cha ngozi ya moto ya Chongqing Songzao "9.27" ndi kutsika kwakukulu kwa Downhole No. 2, kuwonongeka kwakukulu kwa lamba wa malasha. Kutentha kwa lamba kutatha kukwera. Chifukwa cha kulephera kwa chipangizo choteteza kutentha ndi chowunikira utsi chomwe chidayikidwa pa chonyamulira lamba, palibe chenjezo kapena kuyimitsidwa kwa ntchito ya lamba. Zinapangitsa lamba kuyaka moto ndipo zinapangitsa malasha pa lamba kuyaka. Mpweya woopsa komanso woopsa womwe umapangidwa ndi kuyaka udzabwerera kumalo ogwirira ntchito, zomwe zimapangitsa kuti anthu azidwala poizoni.

Malamulo a chitetezo cha migodi ya malasha amanena kuti kuchuluka kwa carbon monoxide mumlengalenga m'migodi ya malasha sikuyenera kupitirira 0.0024%, ndipo carbon monoxide idzapangidwa pamene malasha ayamba kuyaka okha kapena pamene moto wapansi panthaka uchitika. Tonse tikudziwa kuti poizoni wa carbon monoxide ndi woopsa kwambiri. Pambuyo poti carbon monoxide yalowetsedwa m'thupi la munthu, imasakanikirana ndi hemoglobin m'thupi la munthu, kenako imapanga carboxyhemoglobin. Ikhoza kupangitsa hemoglobin m'thupi la munthu kutaya ntchito ndi ntchito yonyamula mpweya, motero ingayambitse hypoxia ndi asphyxia. Ngozi zambiri m'migodi ya malasha nthawi zambiri zimakhala chifukwa cha kupanga kapena kutuluka kwa mpweya woopsa monga carbon monoxide zomwe zayambitsa poizoni kwa ogwira ntchito komanso ngozi zoopsa. Chifukwa chake, pofufuza zachitetezo chathu cha tsiku ndi tsiku, tiyenera kuyang'anitsitsa kwambiri momwe ma alarm a utsi amagwirira ntchito, ma alarm a carbon monoxide ndi zida zina zimagwirira ntchito kuti tipeze chitsimikizo cha chitetezo chathu.

Alamu yokhazikika ya HENGKO ndi chipangizo chodziwira co, chili ndi ubwino woyankha mwachangu, kukhudzidwa kwambiri, mphamvu yolimbana ndi kusokoneza komanso chitetezo cha IP65. Pamene kuchuluka kwa carbon monoxide kupitirira mtengo wokonzedweratu wa chipangizocho, chodziwira nthawi yomweyo chidzatumiza chizindikiro cha alamu chomveka komanso chowoneka.

HENGKO CO sensor module ndi gawo la gasi lapadziko lonse lopangidwa ndikupangidwa pophatikiza ukadaulo wovuta wozindikira zamagetsi ndi dera lovuta. Gawoli limagwira ntchito ndi dera losavuta loyendetsera, lomwe lili ndi kutulutsa kwa digito ndi kutulutsa kwamagetsi a analog, kukhazikika bwino komanso kukhala ndi moyo wautali. Zotsatira za muyeso zitha kuwerengedwa kuchokera ku microprocessor kudzera mu mawonekedwe a I2C a wogwiritsa ntchito.

Kuwonjezera pa alamu yokhazikika ya carbon monoxide, HENGKO ilinso ndichowunikira mpweya chonyamulika m'manjazomwe zimatha kuzindikira kuchuluka kwa mpweya umodzi mosalekeza. Chowunikira chimagwiritsa ntchito kusanthula kwa pampu kuti chizindikire mpweya, ndipo wogwiritsa ntchito amatha kusankha ndodo yoyenera malinga ndi zofunikira zosiyanasiyana za chilengedwe, zomwe zimapangitsa kuti muyeso ukhale wosavuta. Chowonetsera chimagwiritsa ntchito chiwonetsero chachikulu cha OLED dot matrix, chomwe chikuwonetsa kuchuluka, kutalika ndi nthawi yomwe mpweya ukuyesedwa. Njira yosavuta yogwirira ntchito ya makiyi atatu komanso chidziwitso chatsatanetsatane zimapangitsa kuti ntchitoyi ikhale yofupikitsa komanso yosavuta kumva.
