Igenzura ry'umwotsi Urwego rwo kugenzura neza ibidukikije 

Ikwirakwizwa ryumwotsi rigenzura ibibazo mugihe gukurikirana ibidukikije bisaba neza - ntabwo ari ugukeka. Twashyizeho sisitemu zirenga 120 n’amazi y’ubukorikori muri parike y’inganda, mu bigo by’ubwenge, no mu bidukikije kuva mu 2006. Mu mishinga itatu umwaka ushize - ibiri mu Karere ka Heping ka Shenyang n’indi mu kigo cy’ibikoresho by’imiti - twahuye n’ibibazo bisa: umwotsi w’umwotsi uva mu bigega byegeranye byavanze ibyasomwe na sensor, bikurura impuruza zitari nziza, hamwe n’uburinganire bw’ikirere. Nibwo twahagaritse gufata umwotsi nkurusaku rwinyuma-hanyuma dutangira kugenzura intera ikwirakwizwa.

Impamvu Diffusion Urwego Nukuri Irahinduka Mugukurikirana Ibidukikije

Amakipe menshi yibanda kuri sensor sensibilité cyangwa kalibrasi inshuro. Ariko amakuru yimirima yacu yerekana ikwirakwizwa ryiganje kugipimo cyo kwizerwa. Umwotsi ntabwo witwara nka gaze isukuye. Ubucucike bwacyo, ubushyuhe butandukanye, hamwe n umuyaga woguhumeka byerekana aho bigenda mbere yo kugabanuka munsi yumupaka. Mu kizamini kimwe cyegereye uruganda rukora imyenda, umwotsi utagenzuwe wakwirakwije metero 47 mu buryo butambitse mbere yo kumanuka kuri 12 µg / m³ PM2.5 - nyamara ibyuma bifata ibyuma byashyizwe kuri metero 38 uvuye hejuru ya 89 µg / m³ mu minota 11. Nyirabayazana? 1.8 m / s crosswind ikorana nubushyuhe bugezweho buva mumiyoboro ishyushye. Utabanje gupima cyangwa kubuza ibahasha ikwirakwizwa, nta sensor array itanga amakuru yizewe.

Ubu dushushanya ikarita yo gukwirakwiza dukoresheje ibintu bitatu nyabyo-byinjira: umuyaga w’umuyaga waho (upimwa na anemometero ya ultrasonic kuri 2 Hz), umuvuduko wo gusohoka wihuta (ukoresheje umuyoboro wa pitot uhinduranya kugeza kuri ± 1,2% yuzuye), hamwe nubushyuhe bwa delta (IR thermography ihuye nibiryo byikirere). Ntabwo aribwo buryo bwo kwerekana ibintu-nibyo dukoresha. Ibiriho ubu dukoresha itumanaho rya Modbus RTU hagati yikirere cya Vaisala WXT530, Siemens S7-1200 PLCs, hamwe nimyandikire ya Python ivugurura radiyo ikwirakwizwa buri masegonda 9. Ibisohoka bigabanya kugabanya umubiri-ntabwo ari filteri ya software.

Uburyo butatu-bwemewe bwo kugenzura uburyo (nimpamvu ebyiri zananiwe munsi yumutwaro)

Bamwe bavuga ko kugenzura ikwirakwizwa bidakenewe niba "wongeyeho ibyuma byinshi." Twaragerageje. Muri 2023 umuderevu wibibuga bitandatu, gride sensor sensor yagabanije ibyiza byibinyoma 22% gusa -ariko yazamuye amafaranga yo kubungabunga 3.7 ×. Dore icyakora mubyukuri:

• Inzitizi zo gutandukana: 3-mm ibyuma bitagira umuyonga bingana kuri 63 ° kumuyaga wiganje. Yashizeho metero 1,2 hejuru ya sensor cluster. Gabanya umwotsi wapimye winjira 84% muri 18 kuri 21 yumuyaga. Ikora neza mugihe uburebure bwa metero 8.
• Ahantu hashyuha: Umuyaga mwinshi wa axial (ubwoko bwa ECM, 42 dB (A) kuri m 1) washyizwe kuri 0.8 m munsi ya sensor, unaniza 0.45 m³ / s yumuyaga uhumeka hejuru kuri 1.1 m / s. Gukora micro-ivugurura ihamye izamura umwotsi winjira hejuru yindege yumva. Byagenzuwe neza kugeza kuri 2,3 m / s.
• Imyenda y'amazi. Ibitonyanga by'ibicu bifata> 68% bya sub-5 µm ibice mumasegonda 0.9. Irasaba gukomera kwamazi <80 ppm hamwe no kuyungurura. Kunanirwa inshuro ebyiri kubera gupima calcium-ubu rero turerekana neza ceramic-coed nozzles.

Ni iki kidakora? Mugaragaza meshi ya pasifike (ifunze mumasaha 72) hamwe na neutalisale ya chimique (pH idahindagurika yahinduye sensor drift kuri ± 4.3% kumcyumweru). Twamenye ko inzira igoye - mu bimera bibiri byo gutunganya amazi mabi aho umwotsi wuzuye amoniya wakiriye hamwe na mesh yashizwemo zinc, bigakora imyunyu ngororamubiri igabanya ikibanza cya sensor.

Kwishyira hamwe Niho Imishinga myinshi Yatsitara

Igenzura rya Diffusion ntirishobora kubera ko ibyuma bifite inenge-ariko kubera ko byashizwe kumurongo wo gukurikirana umurage. Turabona ibyuho bitatu byisubiramo:

• Guhuza igihe: Ikirere cyerekana buri masegonda 60 mugihe logique yo gukwirakwiza isaba ivugurura buri masegonda 8-12. Gukosora: Ongeraho ibice byo kubara (Raspberry Pi CM4 hamwe na kernel-nyayo) kuri buffer na sample.
• Imbaraga zubutegetsi zivuguruzanya: 24 VDC sensor bisi isangira ikibanza hamwe na 220 ya VAC yumuzunguruko. Bitera urusaku rwa mV 17-23 kumurongo wa 4-20 mA. Gukosora: Opto-yitaruye ibimenyetso byerekana ibimenyetso (Dataforth SCM5B35-03) mbere yo kwinjiza ADC.
• Gushiraho amakosa ya geometrie: Baffles yashyizwe hamwe nicyerekezo cyumuyaga aho kuba perpendicular to plume centerline. Igisubizo: kugabanya 55% mubikorwa. Gukosora: Koresha metero intera ya laser mugihe cyo kwinjizamo kugirango ugenzure inzitizi-ihuza umurongo uhuza ± 2.5 °.

Ubu dushyiramo urutonde rwubushakashatsi bwamanota 15 mbere yo koherezwa-bikubiyemo amashanyarazi yumuriro, hejuru yubuso bugaragara, ndetse nubwinshi bwibimera byigihe (ibihuru byimeza bihindura imyirondoro yumuyaga kugeza kuri 30%). Bifata amasaha 3.5 kurubuga. Abakiriya babyita birenze urugero. Noneho barabona ukwezi kwambere kwamakuru ya stabilite.

Kugenzura Umwotsi Utandukanye Urwego ni Igikorwa gikora - Ntabwo ari ibyuma gusa

Ibi ntabwo ari ukugura agasanduku kanditseho "kugenzura imyotsi ikwirakwizwa." Nijyanye no kwiyemeza guhoraho gupima icyimuka-n'impamvu. Sisitemu yose twubaka ikubiyemo amashusho ya radiyo nzima kuri SCADA HMI, ivugururwa buri masegonda 10. Abakoresha ntibareba indangagaciro gusa ahubwo ibahasha yumubiri irimo. Iyo umuyaga uhindutse, radiyo irongera. Iyo stack temp igabanutse, plume igwa imbere. Ibyo kugaragara bihindura ibyemezo.

Mu ruganda rukora batiri muri Dalian, abakoresha bakoresheje icyo cyerekezo kugira ngo batinye itanura ry’umuyaga kugeza igihe umuyaga uhindukiye ugana iburasirazuba - bagabanya impuruza za CO ku kigero cya 91% muri Q1 2024. Mu rundi rubanza, ikigo cya kaminuza cyahinduye uburyo bwo gutera amasoko bushingiye ku ikarita yo gukwirakwiza igihe, bakoresheje inkingi z’amazi nkinzitizi zihagaritse. Nta byuma bishya-gusa imitungo yagaruwe iyobowe nubwenge bwo gukwirakwiza.

Kugenzura imyotsi ikwirakwizwa no gutangira kwemeza ko ibidukikije bidahagaze. Irahumeka, ihinduka, ishyuha, ikonje. Gukurikirana neza bitangirira aho gukwirakwiza kurangirira - bikarangirira aho kugenzura bitangirira. Ku makipe akomeye kubyerekeranye nibikorwa bifatika, iyo mipaka ntabwo ihinduka kwirengagiza. Nibintu byambere byo gupima, kwerekana, no gucunga.
