Chida cha DT-AEC2531 Choyaka Gasi Chowunikira Chipinda Chapansi Pansi
Mbiri
Mukugwiritsa ntchitochowunikira gasi, zida zosiyanasiyana ndi zida monga mapaipi, malo olowera zipata, zida zowongolera kuthamanga, zitsime za valve, ndi zina. Zida zovuta zoperekera gasi izi ndi maukonde a mapaipi zabweretsa mavuto ambiri pakuwongolera makampani amafuta, makamaka kasamalidwe kavalve ya gasizitsime. Zitsime za valve za gasi zimatha kuyambitsakutayikira kwa gasichifukwa cha ukalamba wa zida, zolakwika, ndi kusagwira bwino ntchito kwa ogwira ntchito. Komabe, kuyang'ana pamanja kwachikhalidwe kumakhala kovuta kuthamangira pamalowa kuti mukalandire chithandizo choyenera nthawi yoyamba chifukwa chakuchulukirachulukira ndikuwunika. Zonsezi zabweretsa zovuta pa kayendetsedwe ka makampani a gasi.
Ubwino wa mankhwala
1) Kugwiritsa ntchito masensa apamwamba a laser (ukadaulo wa tunable laser spectroscopy (TDLAS) wokhala ndi ma alarm abodza otsikandimoyo utumiki kwa zaka 5-10;
2) Landirani kulumikizana kwa NB-IoT ndikuthandizana ndi ogwiritsa ntchito ambiri mongaChinamafoni ndi matelefoni kuti atsimikizire kulumikizana kodalirika;
3) Makina onsewa adapangidwa ndikugwiritsa ntchito mphamvu zochepa komanso nthawi yayitali yogwira ntchito, yomwe imatha kuchepetsa mtengo wokonza zida.
Mbali zazikulu
1) Batire lamphamvu kwambiri(152 Ah)zamtundu woyamba wapakhomo, wodalirika;
2) Kugwiritsa ntchito zida zapamwamba za laser (tunable laser spectroscopy (TDLAS) ukadaulo, ndi high kudalirika, mphamvu zotsutsana ndi kusokoneza, kutsika kwa ma alarm abodza komanso kukonza kwaulere;
3) Adopt NB-IOT opanda zingwe njira kufala kutali, kugwiritsa ntchito mphamvu zochepa, kuphimba lonsendiluso lolumikizana kwambiri;
4) Kuphimba bwino alamu ndi chithandizo chadzidzidzi kuti mupewe ngozi;
5) Ntchito ya Alamu ya kusefukira imazindikira momwe zida ziliri ndikudziwitsa wogwiritsa ntchito kuti zida zili mu nthawi yowonekera pawindo..

6.1 Njira yoyika Detector:
Litikuzindikira gasi woyakandi kulemera kwake kochepa kwambiri kusiyana ndi mpweya monga methane, chojambuliracho chiyenera kuikidwa pafupi ndi mutu wa chitsime (kutalika kwa chitsime sikuyenera kupitirira 30cm)
6.2 Njira yosinthira chivundikiro cha manhole
Chophimba chosinthira chivundikiro cha dzenje chimakhala chokhazikika ku ndege yapansi, ndipo pamwamba pa ndodo yosinthira chivundikiro cha dzenje ndipamwamba kuposa 2cm kuposa chivundikiro cha dzenje (monga momwe tawonetsera pachithunzichi). Pambuyo pa kukhazikitsa, chosinthiracho chikhoza kuyambitsidwa pamene chivundikiro cha dzenje chatsekedwa.
