Kusvika muna 2020.12.5, kwave nerufu rwevanhu 122 mumigodhi yemarasha munyika yese gore rino, zvichiuraya kana kubata vanhu 224. Gore rino, tsaona huru dzekuchengetedza mumigodhi yemarasha (kana tichienzanisa ne2019) dzakawedzera neimwe, uye huwandu hwevanhu vakafa hwakawedzera nevanhu 16, kuwedzera kwe50% ne44% zvichiteerana." Njodzi yemoto yeChongqing Songzao "9.27", vanhu 16 vakafa uye vanhu 38 vakakuvara; Njodzi yemoto yeChongqing Songzao "9.27" yakakonzera rufu rwevanhu 23. Hupenyu hutsva hwakawanda hwakamiswa pasi pemugodhi wemarasha. Kunyange tichizvidemba, kuchengetedzeka kwekushanda kwemugodhi wemarasha kunofanirawo kumutsa kutarisisa kwevanhu uye kuridza bhero rekurira pasi pemoyo wangu.
Mushure mekuongorora kwakakosha, chikonzero chetsaona yemoto yeChongqing Songzao "9.27" iDownhole No. 2 large dip, Kupera kukuru kwebhandi remarasha. Mushure mekunge tembiricha yebhandi yakwira. Nekuda kwekutadza kwemudziyo wekudzivirira tembiricha uye smoke detector yakaiswa pabhandi, hapana yambiro kana kumira kwekushanda kwebhandi. Zvakaita kuti bhandi ribatire moto uye zvakaita kuti marasha ari pabhandi apise. Magasi ane chepfu uye anokuvadza anogadzirwa nemoto achadzokera panzvimbo yebasa, zvichikonzera chepfu yevashandi.
Mitemo yekuchengetedza migodhi yemarasha inoti huwandu hwecarbon monoxide mumhepo mumigodhi yemarasha hahufanirwe kudarika 0.0024%, uye carbon monoxide ichagadzirwa kana marasha angoerekana atsva kana moto uri pasi pevhu ukaitika. Tose tinoziva kuti chepfu yecarbon monoxide ine njodzi huru. Mushure mekunge carbon monoxide yafemerwa mumuviri wemunhu, inozobatana nehemoglobin mumuviri wemunhu, yobva yagadzira carboxyhemoglobin. Inogona kuita kuti hemoglobin mumuviri wemunhu irasikirwe nebasa rekutakura okisijeni, saka inogona kukonzera hypoxia uye asphyxia. Njodzi zhinji dzemigodhi yemarasha dzinowanzova kuburitswa kana kubuda kwegasi rine chepfu senge carbon monoxide kwakakonzera chepfu yevashandi uye tsaona dzinouraya. Saka, mukuongorora kwedu kwezuva nezuva kwekuchengetedza, tinofanira kunyatsoteerera mashandiro enguva dzose ealarm dzeutsi, alarm dzecarbon monoxide nezvimwe zvishandiso kuti tipe vimbiso yekuchengetedza kuchengetedzeka kwedu.
HENGKO fixed co alarm chishandiso chekuona co, chine mukana wekupindura nekukurumidza, kunzwa kwakanyanya, kugona kwakasimba kwekudzivirira kukanganiswa uye IP65 grade protection. Kana huwandu hwecarbon monoxide hukadarika kukosha kwakafanogadzirwa kwechishandiso, detector inotumira chiratidzo chekunyevera chinonzwika uye chinoonekwa pakarepo.
HENGKO CO sensor module imhando yepasi rose yegesi yakagadzirwa uye inogadzirwa nekubatanidza tekinoroji yakaoma yekuona electrochemical nedunhu rakaoma. Chikamu ichi chinoshanda nedunhu riri nyore rekutyaira, rine kubuda kwedhijitari uye kubuda kwemagetsi eanalog, kugadzikana kwakanaka uye hupenyu hurefu. Mhedzisiro yekuyera inogona kuverengwa kubva ku microprocessor kuburikidza neinterface yeI2C yemushandisi.
Pamusoro pekuridza carbon monoxide, HENGKO inewo alarm ye "fixed carbon monoxide".mudziyo wegesi unotakurika unobatwa nemaokoiyo inogona kuramba ichiona huwandu hwegasi rimwe chete. Chinoongorora chinoshandisa pombi yekuongorora gasi, uye mushandisi anogona kusarudza tsvimbo yakakodzera zvichienderana nezvinodiwa zvakasiyana-siyana zvenharaunda, izvo zvinoita kuti kuyerwa kuve nyore. Chinoongorora chinoshandisa chiratidziro cheOLED dot matrix chikuru, chinoratidza pachena huwandu, huwandu uye nguva yazvino yegasi riri kuyerwa. Maitiro ekushanda ari nyore matatu-kiyi uye ruzivo rwakadzama zvinoita kuti mashandiro acho ave mapfupi uye ari nyore kunzwisisa.
