Kusvika muna 2020.12.5, pane vanhu zana nemakumi maviri nevaviri vakafa mumigodhi yemarasha munyika yose gore rino, kuuraya kana kuteya vanhu mazana maviri nemakumi maviri nevana. Gore rino, tsaona huru dzekuchengetedza mugodhi wemarasha (zvichienzaniswa ne2019) dzakawedzera neimwe, uye nhamba yevakafa yakawedzera nevanhu gumi nevatanhatu, kuwedzera kwe50% uye 44% zvakateerana." Chongqing Songzao "9.27" njodzi yemoto, vanhu gumi nevatanhatu vakafa uye vanhu makumi matatu nemasere vakakuvara; Chongqing Songzao "9.27" njodzi yemoto yakakonzera kufa kwevanhu makumi maviri nevatatu. pasi pemoyo wangu.
Mushure mekuongorora kwekutanga, chikonzero cheChongqing Songzao "9.27" njodzi yemoto iDownhole No. Mushure mokunge kupisa kwebhanhire kunokwira. Nekuda kwekutadza kwemudziyo wekudzivirira tembiricha uye utsi detector yakaiswa pabhanhire rekutakura, pakanga pasina nyevero kana kumira kwebhandi kushanda. Zvakaita kuti bhandi ribatire moto zvikaita kuti zimbe raiva pabhandi ripfute. Iwo muchetura uye anokuvadza magasi anogadzirwa nekupisa anoyerera achidzokera kunzvimbo inoshanda, zvichikonzera chepfu yevashandi.
Mitemo yekuchengetedzwa kwemigodhi yemarasha inotara kuti kuwanda kwecarbon monoxide mumhepo mumigodhi yemarasha hakufanire kudarika 0.0024%, uye kabhoni monoxide ichagadzirwa kana marasha emarasha angotsva kana moto wepasi pevhu waitika. Tese tinoziva kuti carbon monoxide poisoning ine ngozi zvikuru. Mushure mekunge kabhoni monoxide yapinzwa mumuviri wemunhu, inosanganiswa nehemoglobin iri mumuviri wemunhu, yobva yagadzira carboxyhemoglobin. Inogona kuita kuti hemoglobin iri mumuviri wemunhu irasikirwe nebasa uye basa rekutakura okisijeni, nekudaro inogona kukonzera hypoxia uye asphyxia. Tsaona zhinji dzemumigodhi wemarasha dzinonyanya asi kugadzirwa kana kubuda kwemagasi ane muchetura akadai secarbon monoxide kwakonzera muchetura wevashandi uye tsaona dzinouraya. Naizvozvo, mukuongorora kwedu kwezuva nezuva kwekuchengetedza, isu tinofanirwa kutarisisa kune yakajairika mashandiro uye kushanda kwehutsi maalarm, kabhoni monoxide maalarm uye zvimwe midziyo yekupa vimbiso yekuchengetedza kuchengetedzwa kwedu.
HENGKO yakagadziriswa co alarm chishandiso chekuona co, ine mukana wekukurumidza kupindura, kunzwisiswa kwakanyanya, kwakasimba anti-kupindira kugona uye IP65 giredhi yekudzivirira. Kana huwandu hwekabhoni monoxide hwadarika kukosha kwechiridzwa, detector inotumira ipapo inonzwika uye inoonekwa alarm chiratidzo.
HENGKO CO sensor module igasi repasi rose rakagadzirwa uye rakagadzirwa nekubatanidza yakaoma electrochemical yekuona tekinoroji nedunhu rakaomarara. Ichi chikamu chinoshanda neinyore dhiraivha yekutyaira, ine dijitari inobuda uye analog voltage kubuda, kugadzikana kwakanaka uye hupenyu hurefu. Mhedzisiro yekuyera inogona kuverengwa kubva kumicroprocessor kuburikidza nemushandisi I2C interface.
Pamusoro peiyo yakagadziriswa kabhoni monoxide alarm, HENGKO zvakare ine ahandheld portable gas detectoriyo inogona kuramba ichiona kuwanda kwegasi rimwe chete. Iyo detector inotora sampling yepombi kuti ione gasi, uye mushandisi anogona kusarudza tsvimbo yakakodzera zvinoenderana nezvinodiwa zvakasiyana zvezvakatipoteredza, izvo zvinoita kuti kuyerwa kuve nyore. Chiratidziro chinotora hombe-screen OLED dot matrix kuratidza, iyo inooneka inoratidza kusungirirwa, huwandu uye nguva iripo yegesi iri kuyerwa. Iyo yakapfava matatu-kiyi maitiro ekushandisa uye yakadzama ruzivo rwekukurumidza inoita kuti oparesheni iwedzere kupfupika uye nyore kunzwisisa.
