Momwe Kusintha kwa AS4747 Water Metering ku Australia Kukuyendetsera Ma Radar Flow Meters ku Outback

Apa ndi pomwe muyezo wa AS4747:2025 wa ku Australia tsopano ukufuna kuyeza kayendedwe kosalekeza, kosasokonezedwa, komanso koyendetsedwa ndi telemetry pamadzi aliwonse olamulidwa omwe amatuluka pamwamba pa Murray-Darling Basin. Muyesowu sutchula ukadaulo winawake wa sensa. Umatchula zotsatira: kulondola mkati mwa ±2.5% pansi pa mikhalidwe yamunda, kapangidwe kake kowoneka bwino kapena kosasokonezedwa, komanso kutumiza deta pafupipafupi tsiku lililonse kupita ku nsanja ya telemetry ya boma.

Kumpoto kwa Chigwa — Barwon-Darling, Gwydir, Namoi, Macquarie — kuphatikiza kwa kayendedwe ka madzi kosalekeza, kudzaza zinyalala, ndi malo akutali kumachotsa ukadaulo wambiri. Ma ultrasound mita omwe ali m'madzi amawonongeka ndi zinyalala. Makina oyezera madzi amawonongeka ndi zinyalala ndipo amalephera kuwononga zinthu — chipata chimatha kutsegulidwa mozungulira iwo. Zipangizo zosiyanitsa kuthamanga kwa madzi zimafuna flume kapena weir yeniyeni, zomwe zimawononga ndalama zambiri.

Chifukwa Chake Radar, ndi Chifukwa Chake Kusalumikizana Ndikofunikira Pano

Njira yoyendetsera kayendedwe ka madzi ya Barwon-Darling ndiyo chifukwa chake. Sensa yoviikidwa m'madzi yomwe imakhala mu ngalande youma kwa miyezi 18 imasonkhanitsa fumbi, ukonde wa akangaude, ndi dzimbiri pankhope yake ya transducer. Pamene kayendedwe ka madzi kafika, kuwerenga koyamba kwa sensa nthawi zambiri kumakhala kolakwika kwa maola 24 mpaka 48 oyambirira - nthawi yomweyo pamene kuyeza molondola ndikofunikira kwambiri, chifukwa nthawi imeneyo ndi pamene madzi akusunthidwa kupita ku malo osungiramo madzi pafamu. Pamene sensayo ikakhazikika, 40% ya kayendedwe ka madzi kamakhala katadutsa kale.

Rada ya Honde imakhala pa gantry yachitsulo mamita 4 mpaka 10 pamwamba pa bedi la channel. Mu nthawi youma ya miyezi 18, sichita chilichonse. Sichiwonongeka. Kuyenda kwa madzi kukafika, kuwerenga kwake koyamba kumakhala kolondola ngati chikwi chake. Gawo la 24GHz Doppler limatenga liwiro la pamwamba kuyambira nthawi yomwe mphamvu yodziwika ikupezeka. Rada ya 60GHz kapena 80GHz imajambula gawo la madzi molondola ±2mm. Purosesa yomwe ili mkati mwake imaphatikiza liwiro, mulingo, ndi geometry yowunikidwa ya channel kuti iwerengere kuchuluka kwa madzi omwe amatuluka nthawi yomweyo mu ma megalita patsiku - gawo lomwe Australian water accounting imagwiritsa ntchito.

Kulowetsa kwa geometry ya magawo osiyanasiyana si kuyerekezera kamodzi kokha. Mbiri ya njira pa nthawi iliyonse yoyambira imafufuzidwa panthawi yoyika ndikulowetsedwa mu kasinthidwe ka sensa. Ngati njirayo isuntha - monga momwe njira zadothi m'malo otsetsereka a nthaka yakuda ku Gwydir Valley zimachitira, makamaka pambuyo pa kusefukira kwakukulu - kafukufukuyo amasinthidwa ndipo mbiri yatsopano imakwezedwa kudzera mu mawonekedwe a RS485 Modbus. Sensayo simatenga geometry yokhazikika. Imavomereza geometry yatsopano nthawi iliyonse njira yeniyeni ikasintha.

Nzeru Yotsimikizira Kusokonezeka

Kugogomezera kwa muyezo wa AS4747 pa kuletsa kusokonezedwa ndi yankho lachindunji ku milandu ya kuba madzi ya 2017–2019 kumpoto kwa Basin, komwe othirira ankaimbidwa mlandu wopopa madzi panthawi ya ziletso ndikugwiritsa ntchito zida zoyezera. Sensa ya radar yosakhudzana ndi kukhudzana yomwe imayikidwa mamita 6 pamwamba pa ngalande pa gantry yachitsulo singathe kutsekedwa, kumizidwa mu chidebe cha madzi osadetsedwa, kapena kupititsidwa ndi chitoliro chobisika. Gantry imawoneka kuchokera mlengalenga ndipo imatha kuwerengedwa ndi zithunzi za satellite zomwe zimawonetsedwa motsutsana ndi deta ya telemetry.

Kuchuluka kwa deta kumawonekera ponseponse. Muyeso uliwonse wa mphindi 15 umayikidwa nthawi, kuikidwa chizindikiro cha geotagged, ndikutumizidwa mwachindunji ku nsanja ya telemetry ya boma la boma — NSW WaterInsights portal kapena Queensland's IWMS — kudzera pa MQTT Json. Palibe kusintha kwa deta komwe kumachitika m'deralo. Palibe mawonekedwe osinthira pamanja. Wogwiritsa ntchito detayo akhoza kuwona detayo. Sangathe kuisintha.

Izi ndizofunikira chifukwa Murray-Darling Basin Plan, mgwirizano wa maboma okwana $13 biliyoni womwe umalamulira kugawana madzi pakati pa New South Wales, Victoria, South Australia, ndi Queensland, umadalira kuwerengera ndalama komwe kungayesedwe. Ngati madzi omwe achotsedwa pa nthawi yopuma ku Gwydir Valley ayesedwa molondola ±2.5% ndikutumizidwa ku nsanja ya boma mkati mwa maola 24, kugawa kwa kayendedwe ka zachilengedwe ku Macquarie Marshes kumatha kuwerengedwa motsimikiza. Ngati muyeso uli ±20% ndipo deta ifika papepala mochedwa miyezi itatu, dongosolo lonse la kuwerengera ndalama limasokonekera. Radar yosakhudzana ndi kukhudzana imatseka kusiyana kumeneko.

Kulumikizana: Kodi "Kutali" Kumatanthauza Chiyani ku Australia?

Chigwa cha kumpoto si chakumidzi kokha. Chili kutali kwambiri ndi malo omwe ma network a masensa aku Europe sangakumane nawo. Malo olima thonje ku Barwon-Darling pafupi ndi Brewarrina ali pamtunda wa makilomita 120 kuchokera ku tawuni yapafupi ndi anthu opitilira 5,000. Mafoni ali m'mbali mwa msewu waukulu wa Kamilaroi. Palibe makilomita 40 kuchokera pamsewu waukulu panjira yadothi yopita ku pampu ya mtsinje.

Ma radar 45 a Honde omwe ali mu AS4747 compliance deployment amalumikizana ndi nsanja za telemetry kudzera mu ma module olumikizirana omwe asankhidwa pamalo aliwonse. Ma radar omwe amafika pamtunda wa makilomita 15 kuchokera ku tawuni — Moree, Narrabri, Walgett, Bourke — amagwiritsa ntchito ma module a 4G. Ma radar omwe amafika m'malo opanda mafoni amagwiritsa ntchito ma module a LoRaWAN omwe amatumiza deta ku zipata zomwe zili pafupi ndi malo osungira tirigu kapena nsanja za Telstra, zomwe zili ndi mtunda wa makilomita 15 mpaka 25 kudutsa malo osalala. Ma radar atatu omwe ali m'madera akutali kwambiri a Paroo River amagwiritsa ntchito satellite backhaul yolumikizidwa ndi LoRaWAN gateway.

Pa mlingo wa offtake, chothirira sichigwirizana ndi mtambo. Data logger yokhala ndi sikirini yoyikidwa mu chipinda chowongolera cha pampu imawonetsa kuchuluka kwa madzi omwe akuyenda mu ma megalita patsiku, kuchuluka kwa madzi omwe amatengedwa tsiku lililonse, komanso kuchuluka kwa madzi omwe akuyenda kwa masiku 30. Wothirira amawunika logger ngati gawo la ntchito yawo ya tsiku ndi tsiku - momwe amawunika kuthamanga kwa madzi ndi kuchuluka kwa mafuta mu pampu.

Pa nthawi ya kafukufuku wa pachaka wokhudza kutsatira malamulo, katswiri wa WaterNSW amafufuza sensa iliyonse pogwiritsa ntchito Handmeter yonyamulika, ndipo ngati zinthu zilola, mita yamagetsi yotsitsidwa kuchokera pa bwato kapena mlatho. Chikalata chowunikira chimakwezedwa ku mtsinje womwewo wa MQTT ndipo chimakhala gawo la njira yowunikira yokhazikika.

Malangizo a Alamu: Pamene Kutulutsa Kuposa Kugawika

Murray-Darling Basin imagwira ntchito pogwiritsa ntchito njira yogawa madzi. Wothirira aliyense amakhala ndi ufulu wopeza madzi pachaka, ndipo chaka chilichonse boma limalengeza kuchuluka kwa madzi omwe amagawidwa malinga ndi kuchuluka kwa madzi osungidwa. Mu chaka chamvula, madzi omwe amagawidwa amatha kufika 100%. Mu chaka chouma, akhoza kukhala opanda madzi kwa ogwiritsa ntchito chitetezo cha anthu onse.

Kuyeza volumetric kosalekeza kwa sensa ya radar ya 3-in-1 kumalola ntchito yomwe kuyesa kwamanja sikungathe: kukakamiza kugawa nthawi yeniyeni. Seva ya Mtambo ndi mapulogalamu amatsata kuchotsedwa kwa chofufumitsa chilichonse motsutsana ndi kuchuluka kwake komwe kwaperekedwa. Kuchotsa kofufumitsa kukafika pa 95% ya gawo, makina otumizira a Alarm amatumiza chidziwitso chodziyimira pawokha kwa wothirira - chenjezo kuti kuchotsa kukuyandikira malire ovomerezeka. Pa 100% ya gawo, kutumizirana kumatha kuyambitsa kutseka kwa pampu yeniyeni ngati makina owongolera a chofufumitsa akakonzedwa kuti azitsatira malamulo okha.

Mu chaka cha madzi cha 2025-2026, chomwe chinali ndi kuchuluka kwa madzi olowera pansi pa avareji kudutsa kumpoto kwa Basin, kutsatira kumeneku kwa magawidwe si njira yophweka. Ndi njira yokakamiza yomwe imalowa m'malo mwa njira yakale yowerengera mita yodzidziwitsa nokha komanso kuwunika kotsatira malamulo mwachisawawa. Deta si yodzidziwitsa yokha. Imadzidziwitsa yokha, imasindikizidwa nthawi, ndikutumizidwa mwachindunji kwa woyang'anira boma.

Zotsatira za M'munda: Northern Basin, NSW, Januwale–Julayi 2026

Kuyamba kugwiritsa ntchito makina oyezera kuyenda kwa radar okwana 45 ovomerezeka ndi CE, omwe ali ndi ma radar 3-in-1, kunayamba kugwiritsidwa ntchito pakati pa Januwale ndi Marichi 2026 m'malo oyendetsedwa bwino m'zigwa za Gwydir, Namoi, ndi Barwon-Darling.

Zotsatira za ntchito pambuyo pa miyezi isanu ndi umodzi:

• Palibe vuto lililonse la masensa mu nyengo yothirira yachilimwe ya 2025–2026, kuphatikizapo kutentha kwa Januwale komwe kunawonetsa kutentha kwa 47°C pa Brewarrina offtakes ndi kugunda kwa madzi kwa March komwe kunasintha Barwon-Darling kuchoka pa youma kufika pa 2,800 megaliters patsiku mkati mwa maola osakwana 72. Radar yosakhudzana ndi magetsi inapulumuka kusinthaku popanda kupsinjika kwa thupi.
• Kutsimikizira kulondola motsutsana ndi muyeso wa makina amagetsi pa malo 8 mwa 45 kunabweza kusiyana kwapakati pa ±3.1% - mkati mwa cholinga cha ±2.5% pa malo 6 mwa 8, ndipo malo awiri otsalawo amafunikira kufufuzidwanso kwa njira pambuyo pa kusefukira kwa madzi mu Marichi.
• Dongosolo lotumizira ma alarm linayambitsa kutsekedwa katatu kwa pampu yotulutsa madzi nthawi ya ulimi wothirira. Pa malo onse atatuwa, wothirirayo sanatsatire yekha kuchotsedwa kwa madzi ndipo akanapitirira malire a kuchotsedwako ndi pafupifupi 8–15% malinga ndi dongosolo lakale lodzinenera lokha.
• Kuchuluka kwa deta ya MQTT Json kunafika pa 97.3% pa ​​malo onse 45 — kupitirira 95% yocheperako yomwe inafotokozedwa pansi pa AS4747:2025. Kusiyana kwa deta ya 2.7% kunakhazikika m'masiku 6 mu February pomwe kulephera kwa Telstra m'chigawo kunakhudza kulumikizana kwa 4G m'malo 7. Malo a LoRaWAN sanakhudzidwe.
• Kutengera momwe ntchitoyi yayendera, Dipatimenti ya NSW Department of Climate Change, Energy, Environment and Water yavomereza kukulitsa ntchito zina 120 ku North Basin, ndipo kugula kukuyembekezeka kuyamba mu kotala lachitatu la 2026.
