Kubva pakutarisa kubuda kwemvura murwizi kuti ufanotaura nezvemafashamo kusvika pakutevera kubuda kwemvura yakasviba mumiti yekurapa, mita idzi dzinovhara mukaha wakakosha mukutarisira mvura. Kudzokorora kwemazuva ano, kwakashongedzwa netekinoroji ye ultrasonic, radar, kana weir/flume-based, kwakashandura zviyero zvaimboitwa nemaoko, zvinokanganisa kuita data renguva chaiyo, rakarurama, zvichiita kuti zvive zvakakosha pakuchengetedzwa kwezvakatipoteredza, kutevedzera maindasitiri, uye kushanda zvakanaka kwekurima.
Zvakanakira Zvikuru
Ma "open-channel flowmeters" anozivikanwa nekugona kwawo kugadzirisa matambudziko akasiyana ekuyerera kwemvura kusina kumanikidzwa. Simba rawo guru nderekuchinjika kumarudzi akasiyana-siyana ema "channel". Ingave kuyera kuyerera kwemvura mumugero wakamanikana weindasitiri, rwizi rwakakura, kana "concrete water waste channel", mamita aya anogona kugadzirwa kuti aenderane nehupamhi hwakasiyana, kudzika, uye materu - hapana chikonzero chekuchinja mapombi anodhura. Kusiyana nema "closed-pombi metres", anobatawo kuyerera kwemvura ine zvinhu zvakasimba zvakanyanya (semuenzaniso, tsvina ine marara kana mvura yerwizi ine sediment) pasina kuvhara. Mamodheru mazhinji, akadai se "ultrasonic open-channel flowmeters", anoshandisa masensa asingabatanidzi mvura zvakananga, kudzivirira kusvibiswa uye kuderedza kugadziriswa.
Chimwe chinhu chakakosha ndechekuti dzinoshandisa mari shoma pakuyerera kwemvura yakawanda. Kutarisa nzizi dzakakura kana nzira huru dzemvura ine tsvina dzine masisitimu emapaipi akavharwa kunoda mapaipi anodhura, akakura—mhinduro isingashande. Ma flowmeters akavhurika, nekusiyana, anoshanda nemachannel aripo, achideredza mari yekuisa. Anopawo kururama kwakavimbika kana akabatanidzwa nekuongororwa kwenzira kwakakodzera. Semuenzaniso, kana ikashandiswa ne weir (dhamu diki rinogadzira pateni inozivikanwa yekuyerera kwemvura), kururama kunogona kusvika ±2%, zvichisangana nemitemo yakasimba yekuzivisa nezvezvakatipoteredza uye kutevedzera mitemo yeindasitiri. Pamusoro pezvo, mamodheru emazuva ano anoshandisa simba shoma, zvichiita kuti akwanise kunzvimbo dziri kure (semuenzaniso, nzira dzekudiridza dzekumaruwa) uko simba regrid risingawanikwe.
Mapurogiramu Epanyika Chaiwo
Kushanda kwakasiyana-siyana kwema "open-channel flowmeters" kunoita kuti ave akakosha munzvimbo dzakasiyana-siyana. Mukutarisa nharaunda, akakosha pakutarisira nzizi nehova. Nyanzvi dzezvemvura dzinoashandisa kuyera kuyerera kwemvura (huwandu hwemvura inoyerera panguva imwe neimwe) munzizi, vachipa data rekufanotaura mafashamo, kuongorora njodzi dzekusanaya kwemvura, uye kuchengetedza nharaunda dzemumvura. Semuenzaniso, panguva yekunaya kwemvura yakawanda, data rekuyerera kwemvura kubva pamamita aya rinobatsira mapoka e emergency kupa yambiro yemafashamo, kuchengetedza nharaunda dziri pedyo. Anotarisawo kuyerera kwemvura mumadziva nemadziva, achitsigira kutarisirwa kwemvura kwenguva refu.
Mukugadzirisa mvura yakasviba, ma "open-channel flowmeters" anodiwa nemutemo. Ma "treatment plants" anoashandisa kuyera kupinda kwetsvina isina kucheneswa uye kubuda kwetsvina yakanatswa, zvichiita kuti mitemo yezvakatipoteredza itevedzerwe inodzikamisa kuburitswa kwetsvina. Anotevedzerawo mwero wekuyerera kwemvura mumatangi e "air eration" nema "sedimentation basin", achigadzirisa maitiro ekurapa kuti aderedze kushandiswa kwesimba uye kuvandudza kushanda zvakanaka. Kune zvivakwa zvemaindasitiri (semuenzaniso, mafekitori, nzvimbo dzekuchenesesa mvura), aya ma "meter" anoongorora kuyerera kwemvura yakasviba yemaindasitiri isati yapinda muma "sewers" eruzhinji, zvichidzivirira kuwanda kwe "systems" dzekurapa dzemaguta.
Chikamu chekurima chinoshandisa ma "open-channel flowmeters" ekudiridza nemazvo. Varimi vanoashandisa kuyera kuyerera kwemvura mumigero nemakomba, vachiona kuti zvirimwa zvinowana mvura yakakwana—kwete kupfuura, kwete pasi. Izvi hazvingochengetedze mvura yakachena chete (chinhu chinokosha munzvimbo dzakaoma) asiwo zvinoderedza mari inokonzerwa nekudiridza zvakanyanya, zvakaita sekukurwa kwevhu uye kuyerera kwezvinovaka muviri. Mumabasa makuru ekurima, ma "meters" aya anobatanidzwa nema "otomatiki irrigation systems", zvichibvumira kudzora kure uye kutonga kwemvura kunotungamirirwa nedata.
Magadzirirwo Akakosha
Kuti zvienderane nezvinodiwa nechikamu chimwe chete, ma "open-channel flowmeters" anouya nenzira dzakasiyana-siyana. Ma "ultrasonic open-channel flowmeters" ndiwo anonyanya kushandiswa, achishandisa mafungu eruzha kuyera huwandu hwemvura pasina kubatwa. Akanakira kurapwa kwemvura yakasviba (uko mvura yakasviba) uye kutarisa nharaunda (uko kuyerwa kusingapindi mvura kunosarudzwa). Mazhinji acho ane tembiricha inodzorwa, zvichiita kuti zvive nyore kuiona kunyangwe mumamiriro ekunze akaipisisa (kubva munguva yechando kusvika muzhizha rinopisa).
Ma "radar open-channel flowmeters" anobudirira munzvimbo dzakaoma. Anoshandisa mafungu eredhiyo kuyera huwandu hwemvura, zvichiita kuti akwanise nzvimbo dzine guruva rakawanda, mhute, kana utsi (semuenzaniso, nzvimbo dzeutsi dzemaindasitiri kana nzvimbo dzekurima dzine hunyoro). Kusiyana nema "ultrasonic models", ma "radar metres" haakanganisike nekupisa kwemhepo kana hunyoro, zvichipa kururama kwakafanana mumamiriro ezvinhu akaoma. Anogara kwenguva refu, ane nzvimbo dzisingapindi mvura, sinou, nemhepo ine simba.
Pamashandisirwo anoda kunyatsorongeka, maflowmeter akavakirwa pa weir ne flume ndiwo mwero wepamusoro. Weir igedhi rine pamusoro wakachekwa rinogadzira patani yekuyerera inofanotaurwa; flume inzira yakamanikana, yakagadzirwa nenzira yakakosha inokurumidza kuyerera. Nekuyera huwandu hwemvura pamusoro pe weir notch kana mukati me flume, mita idzi dzinoverenga mwero wekuyerera nekunyatsojeka. Dzinowanzo shandiswa mumafekitori ekuchenesa mvura yakasviba, maindasitiri, uye marabhoritari uko kutevedzera mitemo kunoda kuyerwa kwakanyatsojeka.
Kuiswa uye Kugadziriswa
Kuisa zvakanaka ndiko kwakakosha pakuita kuti maflowmeters avhurwe. Danho rekutanga kugadzirira machannel: chiteshi chinofanira kunge chakatwasuka uye chisina marara kanenge kagumi kupfuura hupamhi hwechiteshi kumusoro uye kashanu kupfuura mita. Izvi zvinoita kuti mvura ifambe zvakanaka, izvo zvakakosha pakuyera nhanho nemazvo. Kune mameters anobva ku weir- kana flume-based, weir/flume inofanira kuiswa nhanho uye yakabatana nechiteshi kudzivirira kukanganisa kwemvura. Mameters asingabatanidzi (ultrasonic, radar) anofanira kuiswa zvakananga pamusoro pemvura, pasina zvipingamupinyi (semuenzaniso, mapaipi, matavi) pakati pe sensor nepamusoro pemvura.
Zvinodiwa pakugadzirisa zvinhu zvishoma asi zvakakosha. Pamamita emagetsi emagetsi neradar, kuchenesa masensa kunoitwa nguva nenguva—guruva, tsvina, kana tsvina yeshiri pasensa zvinogona kuvhara zviratidzo, zvichikonzera kuverenga kusina kururama. Mukushandiswa kwemvura yakasviba, kutarisa furo (rinogona kukanganisa kuyerwa kwemazinga) uye kuisa michina inopwanya furo kana zvichidikanwa kwakakosha. Matanda emvura nemagetsi zvinoda kuongororwa nguva dzose kubvisa marara (semuenzaniso, mashizha, marara) anogona kuvhara notch kana channel, zvichikanganisa kuyerera kwemvura. Kuenzanisa kunokurudzirwa gore rega rega, uchishandisa flowmeter inotakurika kuti uone kururama uye kugadzirisa marongero kana zvichidikanwa. Mamita mazhinji emazuva ano anewo maficha ekuzviongorora, achizivisa vashandisi nezvematambudziko akadai sebhatiri shoma kana kusashanda zvakanaka kwesensa.
Mafambiro Emangwana
Remangwana rema "open-channel flowmeters" riri muhunyanzvi hwakangwara uye hwakabatana. Kubatanidzwa kweIoT inzira huru—ma "next-generation metres" achatumira data rekuyerera panguva chaiyo kuma "cloud platforms" kuburikidza ne "wireless networks" (LoRaWAN, NB-IoT). Izvi zvinobvumira kutarisa kuri kure, kunyangwe munzvimbo dziri kure senge "ma "canal" ekumaruwa kana "wilderness" nzizi. Semuenzaniso, masangano ezvakatipoteredza anogona kutevera kuyerera kwenzizi munzvimbo imwe kubva pa "central dashboard", achiona zvinhu zvisina kujairika (semuenzaniso, kuwedzera kamwe kamwe kubva mumvura zhinji) uye kukurumidza kupindura mafashamo.
Kuongorora kunoitwa neAI kuchawedzera kushandiswa kwedata. Nekuongorora data rekare rekuyerera, masisitimu eAI anogona kufanotaura maitiro ekuyerera kwedata mune ramangwana—kubatsira varimi kuronga nguva yekudiridza kana kuti zvirimwa zvemvura yakasviba kugadzirira kupinda kwemvura yakawanda. AI inogonawo kuona zvinhu zvisina kujairika (semuenzaniso, kudzikira kamwe kamwe kwemvura kunoratidza kuti chiteshi chakavharwa) uye kutumira zviziviso, zvichideredza nguva yekushanda uye kudzivirira matambudziko anodhura.
Kushandiswa kweminiaturization uye kutakurwa kuchaita kuti mashandisirwo awedzere. Ma flowmeters akamanikana, anoshandiswa nebhatiri, achave akajairika pabasa remumunda—nyanzvi dze hydrologists dzinogona kuatakura kuenda kuma streams ari kure kunotora data renguva pfupi, kana kuti nyanzvi dzinogona kuashandisa kugadzirisa matambudziko ekuyerera kwemvura muma streams emaindasitiri. Aya mamodheru anotakurika achave nema interfaces ari nyore kushandisa uye kutamisa data pasina waya, zvichiita kuti kuyerwa kuve nyore panzvimbo yacho.
Mhedziso
