E waru tau te roa i te mutunga ka mutu te piki arawhata ki te tirotiro i te kura wai
Ko Zhou tōku ingoa, ā, kua tata ki te waru tau ahau i roto i te aunoatanga wai. Ki te pātai mai tētahi ki a au he aha te mea i tino rerekē i tēnei raina mahi, E kore au e hoatu ki a koe ētahi kupu pēnei i "te hurihanga IoT." Māku tēnei e kōrero ki a koe: kua kore ahau e riwhi i roto i ngā hiripa i roto i te hukarere i te Rā o te Tau Hōu ki te tirotiro i te nui o te korohū e toe ana i roto i tētahi kura propane i waho ake.
Ko ngā pūrākau i raro nei he āhuatanga tūturu katoa i ora ai ahau, i aku kiritaki rānei. Māku e whakatakoto ngā tau me ngā tauhokohoko i kōwhaitia e mātau i taua wā - nā te mea kāore i ngāwari te kōwhiri i tētahi pūoko pēnei i te "hoko noa i te mea utu nui."
1. I taua hōtoke i tata ngaro ai te wera o taku whaea
Ka tīmata ki tōku ake whānau. E noho ana taku whaea i te taiwhenua i Hebei, me te 500 kārani (tata ki te 1,900-rita) Te kura propane noho i te tuawhenua e whāngai ana i te paera e mau ana i te pakitara. Tae noa ki ngā tau tata nei, ia hōtoke me paihere ia, haere atu, me te wetewete i te pū ine hei pānui i te waea. I te hōhonutanga o te hukarere, kāore i taea e ia te tae atu ki reira. Kotahi tau, i te mutunga o Hakihea, kua maroke te kura; I katia te kaiwhakarato mo nga hararei, E rua rā i weto ai te paera, ā, tata tonu te whakatotoka, te pakaru o ngā paipa wai.
Nō muri mai ka tāutatia e au tētahi kaupane taumata ahokore me LoRaWAN mōna. Ehara te kī i te pūoko ātaahua - he kōwae māmā noa iho e mau ana ki runga i te kura e ine ana i te pēhanga korohū kōpeke, ā, ka tahuri ki te taumata wai - engari nāna i pana te raraunga ki te kapua, me ngā ture e rua kua tatūria:
Taka ki raro 20% ā, ka tuku aunoa i tētahi SMS ki a au me te kaiwhakarato hinu a taku whaea;
Kei te backend o te kaiwhakarato, I whakahiatohia e rātau ngā raraunga, ā, ka kite 11 Ko nga whare o te rohe i raro katoa 25%, nā reira ka tukuna e rātau tētahi taraka me te whakakī anō i a rātou katoa i roto i te haerenga kotahi.
Raraunga hei pūrua: Ko te tikanga e toru nga haerenga o taua taraka; te whakakotahi i a rātou ka tapahia te maero me te mahi mā te tata ki 60%, ā, i heke iho ngā haukoti whakamahana a tōku whaea mai i te 1–2 wā i te tau ki te kore.
Te whakawhitiwhiti: He tino raruraru te pānuitanga o LoRaWAN i ngā wāhi tawhiti. He ngoikore te tohu i te marae o taku whaea, nā reira me tāpiri e au he $8 pūhihi o waho i runga i te tuanui hei kawe mai i te tere ngaronga pōkai mai i 15% tae noa ki raro 1%. Ehara i te ātaahua, engari ki te kore e matapo te pūnaha katoa.
2. Te "moepuku huka" o te Plating Plant: Ultrasonic rānei?
Ko taku kaupapa mahi tuatahi ko tētahi tipu hiko paetata. I hiahiatia e rātau he inenga whakapā kore i runga i te waikawa pūhauota 6 mita te roa (HCl) kura — He tino waikura te HCl ka pirau te whakakā mānu kāhua hoapā i roto i te marama kotahi, ehara rawa i te kōwhiringa.
Hei penapena moni, I haere ahau me te ultrasonic i te tuatahi. Mātāpono ngāwari: whakaputa i tētahi ngaru oro auau-tiketike mai i runga, ine i te wā pāoro. Mō ngā wiki tuatahi e rua he tino pai, Ngā pānui pūmau i roto i te ±2 cm. Kātahi ka pā mai te wā marangai. Ka tīmata te kohu waikawa e piki ake ana i te waha o te kura me te huka i ngā pānuitanga ultrasonic - i tētahi rā ka whakaaturia "40% mauī," engari i te wā ka unuhia e te papu, Kua putu kē te kura, ā, ka wera tētahi $1,700 papu autō.
He aha te hē? E whakawhirinaki ana te ultrasonic ki te tere o te oro, ā, ka whakahawea taua tere i te pāmahana, kohu, me te huka. Ko te waha o te kura HCl e kōpikopiko tonu ana i roto i te kohu waikawa - he rite ki te puru paraikete mātotoru ki runga i te pūoko.
I muri i te paunatanga, I whakawhiti ahau ki te hihiani. Ka whakamahi te hihiani i ngā ngaru autōhiko, e tata ana ki te kore e pāngia e te kohu me te huka, ā, he pūmau hoki i runga i te viscous, wai mata kore ōrite (pēnei i te paru hinu taumaha i whangangatia hoki e rātau ā muri ake). Te utu:
I peke te utu wae mai i te tata ki $420 mō te ultrasonic ki te āhua $1,260 mō te hihiani — e toru ngā wā;
Engari kore rawa te papu i wera anō, me ngā wāhanga penapena me te wā whakahekenga o te tau i utua mō taua mea.
Kotahi te raina i akona ai ahau e taua mahi: I roto i te whakakino, mārire, ngā āhuatanga taumaha kohu rānei, Kaua e tīpoka i ngā rau tāra mō te hoapā, te ultrasonic rānei — ko te hihiani te kōwhiringa māmā i te wā roa.
3. Te poka hōhonu o raro me te pūoko "e whakatō ana i te wai"
Ko te kēhi tuatoru ko te kura pūreirei wai o tētahi pāmu i raro i te taha, tanumia 12 mita hohonu, hōhonu me te whāiti, kāore he arawhata hei piki iho. Te whakairinga ultrasonic, hihiani rānei mai i runga? He iti rawa te waha o te kura, ā, he kopikopiko te ara — kāore i tika te pānga o te ngaru.
Koinei te wāhi o te hydrostatic (ruku) Ko te kaituku pēhanga anake te whakautu tika. E noho ana i raro tonu o te kura, te ine i te pēhanga o te tīwae wai ki runga, ā, me te kiato e mōhiotia ana ka tātai anō koe i te rōrahi. Ko te "whakatōpū i roto i te wai" tōna whāinga hoahoa - he tino ārai ki te huka mata me te pārekareka rere.
Raraunga hei pūrua: I whakamahia e te pāmu te tuku i tētahi tangata kotahi i te marama ki te ine ā-ringa, me ngā hapa tae atu ki te ±10%; i muri i te tāuta i te wae hydrostatic me te hopu haere tonu mō te toru marama, ka noho tonu te whakarerekētanga ki te tōkarikari ā-ringa < 1%.
Te whakawhitiwhiti: Ko te hē kino o te wae hydrostatic ko tōna whakaaro kiato. Mō tētahi wā ka whakawhiti rātau i ngā pūtake wai, ā, ka pōuri te wai; kua nekehia te kiato 3%, a, ka rere nga panui. I muri iho ka tāpirihia e au tētahi whakamaumahara "tōkarikari kiato ia hauwhā" i runga i te pūhara - ahakoa te pai o te hangarau, kāore e taea e ia te huri i te waenga anō.
Tētahi atu take ā-ringa: Kāore he hiko mātiti o te pāmu. I kōwhiria e au tētahi hiko iti rawa + pūhiko rītīmu + putanga paewhiri kōmaru iti, kua whakatauria mō 5 tau tūtatari. Ko te mea pono i oma 3.5 tau i mua i te matenga o te pūhiko — i mua i te whakatauranga — nā te mea he kōhukihuki aua hōtoke o Hebei, ā, i taka poto te whakarunga o te kōmaru. Ko tētahi atu akoranga i roto i te "whakatauranga tohu vs. taiao tūturu."
4. Te Takanga Waipuke: Kotahi rau ngā wā o te pūoko te whaina
Ko te mea tino whakamataku ko te teihana tuari diesel a tētahi hoa. I whakawhirinaki ta rātau kura diesel 30 mita pūtoru ki te mātakitaki ā-ringa. Kotahi pō i te wā o te utanga, Ka haere te kaiwhakahaere ki te kai; i te wā i hoki mai ai ia, i runga katoa te tīni i te papa. Ko te whaina taiao ko $11,000, me te whakaweto e rua wiki.
I hoatu e au ki a rātau he raka taumata tiketike: i 90% Ka whakaoho te pūoho tiketike, me te 95% ka tukuna he tohu hāngai ki te papu utanga hei kati aunoa i te kōrere. Ehara tēnei i te "tirohia" - he "mahi māu."
Ki tērā ahunga, Ka tukitukia hoki e te taumata iti ngā taputapu. Ka rere tonu te rua papu a tētahi atu kiritaki ki te kore, ā, ka maroke te mīhini; Neke atu i te utu o te whakakapi IT $850. I muri i te tāpiri i te parenga oma-maroke, ka tū aunoatia te papu 5 hēkona i mua i te maroke.
He mārama te pāngarau: he rongo + E $1,400–2,800 pea te utu o te mōkī mana me te raka — iti iho i te kotahi maringi, i te papu kotahi rānei.
5. i te taha o te taone: E hia rau ngā pae, Kāore he tangata e taraiwa haere ana
Whakamutunga, he mea nui. I whai wāhi ahau ki tētahi whakamohoatanga whakahaere wai mamao mō tētahi takiwā i te raki o Haina, e tūhono ana i ngā taumata o ngā puna 200 me ngā rua parakaingaki e marara ana i ngā pātiki ki SCADA. I mua, I ia wā waipuke ka tukuna e rātau he waka ki te tirotiro i ia waka; Ināianei ka whakaatu te mata matua i ngā mea katoa i te tirohanga kotahi, ā, mai i ngā ia ka taea e rātou te matapae i te 6–12 haora ki mua ko tēhea poka ka waipuke, ko tēhea awa rānei ka piki.
Raraunga hei pūrua: I muri i te whakamohoa, i taka ngā tukunga āpure o te wā waipuke mai i 40 haerenga tangata/rā ki raro 5, mā te matapae, kaua ko te patu ahi.
Te whakawhitiwhiti: Kei te whakaurua te tāwhiti a SCADA me O&M, ehara i ngā pūoko. ērā 200 I kōrero ngā pae i ngā kawa rerekē; E rua marama noa iho te roa o te kōrero. Ā, i muri iho, kei te hiahia tonu koe ki tētahi tangata e mātakitaki ana i te pūhara kia kore ai e heke iho. Ka taea e te hangarau te tiaki mahi, Engari kāore e taea te whakakore i te hiahia mō "tētahi tangata e mōhio ana me pēhea te whakamahi."
