Capacitive level mita m'minda ya paddy

Monga malo ofunikira kubzala mbewu, kuthirira ndi kasamalidwe ka madzi m'minda ya paddy kumathandizira kwambiri pakukolola ndi kukolola mpunga. Ndi chitukuko cha ulimi wamakono, kugwiritsa ntchito bwino ndi kuyang'anira madzi a madzi kwakhala ntchito yaikulu. Capacitive level mita pang'onopang'ono yakhala njira yabwino yowunikira madzi am'munda wa paddy chifukwa chakulondola kwake, kukhazikika komanso kulimba kwake. Nkhaniyi ifotokoza za mfundo zogwirira ntchito, ubwino wogwiritsa ntchito, zochitika zothandiza komanso chiyembekezo cha chitukuko cha capacitive level mita paminda ya paddy.

1. Mfundo yogwiritsira ntchito capacitive level mita
Mfundo ntchito capacitive mlingo mita zachokera kusintha capacitance. Pamene madzi mlingo wa madzi sing'anga kusintha, lolingana dielectric zonse madzi amakhudza capacitance wa capacitor, potero kuzindikira muyeso wa madzi mlingo. Masitepe enieni ndi awa:

Kapangidwe ka capacitor: Capacitive level mita nthawi zambiri imakhala ndi ma elekitirodi awiri, imodzi yomwe ndi probe ndipo inayo nthawi zambiri imakhala waya wapansi kapena chidebe chokha.

Kusintha kosalekeza kwa dielectric: Kusintha kwamadzimadzi kumapangitsa kusintha kwa sing'anga pakati pa ma elekitirodi. Mulingo wamadzimadzi ukakwera kapena kutsika, dielectric constant mozungulira ma elekitirodi (monga dielectric constant of air ndi 1, ndipo dielectric constant of water ndi pafupifupi 80) amasintha.

Capacitance muyeso: The mlingo mita mosalekeza amayang'anira kusintha capacitance kudzera dera, ndiyeno otembenuka mu manambala linanena bungwe mlingo wa madzimadzi.

Kutulutsa kwa siginecha: Mulingo wa mita nthawi zambiri umatumiza mulingo wamadzimadzi woyezedwa ku makina owongolera kapena chipangizo chowonetsera kudzera pa siginecha ya analogi (monga 4-20mA) kapena siginecha ya digito (monga RS485).

2. Makhalidwe a capacitive level mita m'minda ya paddy
Kupanga ndi kugwiritsa ntchito capacitive level mita m'minda ya paddy kumaganizira za chilengedwe cha munda wa paddy. Makhalidwe ake amawonekera makamaka m'mbali zotsatirazi:

Kuthekera kwamphamvu kotsutsana ndi kusokoneza: Chilengedwe m'munda wa paddy ndizovuta, ndipo mita ya capacitive level nthawi zambiri imagwiritsa ntchito mabwalo oletsa kusokoneza popanga kuti pakhale bata lalikulu pansi pa chinyezi ndi kusintha kwa nyengo.

Kuyeza kolondola kwambiri: The capacitive level mita ingapereke kulondola kwa mulingo wamadzi a millimeter, yomwe ili yoyenera kuyang'anira bwino ulimi wothirira ndi madzi.

Zida zolimbana ndi dzimbiri: M'minda ya mpunga, mita ya mulingo iyenera kukana dzimbiri kuchokera m'madzi, dothi ndi mankhwala ena, kotero kuti kafukufukuyu nthawi zambiri amapangidwa ndi zinthu zosapanga dzimbiri (monga chitsulo chosapanga dzimbiri, pulasitiki, ndi zina).

Zosavuta kukhazikitsa ndi kukonza: The capacitive level mita ndi yosavuta kupanga, satenga malo ambiri kuti akhazikike, ndipo ndi yosavuta kuisamalira, kuti ikhale yoyenera kugwiritsidwa ntchito kumidzi.

Ntchito yowunikira patali: Mamita ambiri a capacitive level m'minda ya mpunga ali ndi ma module olumikizirana opanda zingwe, omwe amatha kuzindikira kuyang'anira patali ndi kasamalidwe ka data, ndikuwongolera mulingo wanzeru pakuwongolera ulimi wothirira.

3. Ubwino wogwiritsa ntchito ma capacitive level mita m'minda ya mpunga
Kasamalidwe ka gwero la madzi: Poyang’anira mmene madzi akuchulukira m’minda ya mpunga, alimi angathe kuweruza molondola zosoŵa za ulimi wothirira, kuchepetsa kuwononga madzi, ndi kuwongolera mmene madzi amagwiritsira ntchito bwino.

Wonjezerani zokolola: Kuyang'anira madzi asayansi kungalimbikitse kukula ndi kukula kwa mpunga, kuonetsetsa kuti madzi ali ndi madzi okwanira, komanso kupewa kuchepetsa kupanga komwe kumachitika chifukwa cha kusowa kwa madzi kapena kuchuluka kwa madzi.

Ulimi wanzeru: Kuphatikiza ukadaulo wa sensor ndi intaneti ya zinthu, capacitive level metres zitha kuphatikizidwa mudongosolo lonse laulimi kuti apange njira yothirira mwanzeru ndikukwaniritsa ulimi wolondola.

Kupanga zisankho mothandizidwa ndi deta: Kupyolera mu kuyang'anira ndi kuwunika kwanthawi yayitali kuchuluka kwa madzi, alimi ndi oyang'anira zaulimi amatha kupanga zisankho zambiri zasayansi, kukulitsa njira zaulimi ndi nthawi, ndikukweza kayendetsedwe kaulimi.

4. Nkhani zenizeni
Mlandu 1: Kusamalira mlingo wa madzi m'munda wa mpunga ku Vietnam
M'munda wa mpunga ku Vietnam, alimi mwamwambo amadalira macheke amadzi pamanja kuti azithirira. Njirayi ndiyosagwira ntchito komanso imakonda kulakwitsa chifukwa cha kuweruza kokhazikika. Pofuna kupititsa patsogolo luso la kagwiritsidwe ntchito ka madzi, alimi adaganiza zoyambitsa ma capacitive level metre ngati zida zowunikira madzi.

Pambuyo poyika capacitive level mita, alimi amatha kuyang'anira kuchuluka kwa madzi a m'munda wa mpunga mu nthawi yeniyeni ndikupeza deta ya madzi nthawi iliyonse kupyolera mu kulumikiza opanda zingwe ndi mafoni a m'manja ndi makompyuta. Mlingo wamadzimadzi ukakhala wotsika kuposa mtengo womwe wayikidwa, dongosololi limakumbutsa alimi kuthirira. Kupyolera mu njira yanzeru imeneyi, alimi achepetsa kwambiri zinyalala zamadzi ndikuwonjezera ulimi wa mpunga ndi 10%.

Mlandu wachiwiri: Njira yothirira mwanzeru m'minda ya mpunga ku Myanmar
Famu ina yaikulu ku Myanmar inayambitsa makina a capacitive level meter ndipo anaiphatikiza ndi masensa ena kuti apange njira yanzeru yoyendetsera ulimi wothirira. Dongosololi limangosintha kuchuluka kwa madzi amthirira powunika molondola kuchuluka kwa madzi, chinyezi cha nthaka ndi kutentha.

Mu ntchito yoyesa pafamuyo, mita ya capacitive level meter idazindikira kutentha ndi kuchepa kwa chinyezi cha nthaka, ndipo kachitidweko kanangoyambitsa ulimi wothirira kuti minda yampunga ilandire madzi okwanira nthawi yamvula. Zotsatira zake, kukula kwa mpunga kunafupikitsidwa, mitundu ingapo idakwaniritsidwa bwino munyengo imodzi, ndipo kutulutsa konse kwamunda kunakwera ndi 15%.

Mlandu 3: Pansi pa mbande za mpunga ku Indonesia
Mu mpunga mbande m'munsi ku Indonesia, pofuna kuonetsetsa bata la mlingo wa madzi pa siteji mbande, bwana anayambitsa capacitive mlingo mita. Mazikowo amawunika mosalekeza kuchuluka kwa madzi, kuphatikiza zida ndi njira yayikulu yowunikira deta, ndipo nthawi zonse amasintha mulingo wamadzi.

Kupyolera mu deta yeniyeni, oyang'anira adapeza kuti madzi otsika kwambiri angakhudze moyo wa mbande, pamene kuchuluka kwa madzi kungayambitse matenda ndi tizilombo towononga. Pambuyo pa miyezi ingapo ya kukonzanso ndi kukhathamiritsa, kuwongolera kwa madzi kunakwaniritsidwa molondola, ndipo kupambana kwa kulima mbande kunawonjezeka ndi 20%, zomwe zinalandira ndemanga zabwino zamsika.

5. Chiyembekezo cha chitukuko
Ndi kupita patsogolo kosalekeza kwaukadaulo waulimi, chiyembekezo chogwiritsa ntchito ma capacitive level metres m'minda ya mpunga ndi yayikulu. Chitukuko chamtsogolo chikuwonekera makamaka muzinthu izi:
Kuphatikizika kwanzeru: Phatikizani ma capacitive level metre ndi masensa ena (monga kutentha ndi chinyezi, masensa a chinyezi m'nthaka, ndi zina zotero) kukhala nsanja yanzeru yoyendetsera ulimi kuti mukwaniritse kuwunika ndi kasamalidwe kokwanira.

Ukadaulo woyankhulirana opanda zingwe: Ndi chitukuko chaukadaulo wa intaneti wa Zinthu, ma level metre adzatengera kwambiri ukadaulo wolumikizirana opanda zingwe kuti muchepetse kuyika, kupititsa patsogolo kutumizirana ma data, komanso kuzindikira kuwunika kwakutali.

Kusanthula deta ndikugwiritsa ntchito: Kupyolera mu umisiri wapamwamba kwambiri monga chidziwitso chachikulu ndi luntha lochita kupanga, kufunikira kwa data yoyezera mulingo wamadzimadzi kumakumbidwa kuti apereke chithandizo chowonjezera pazaulimi.

Kupititsa patsogolo luso laukadaulo: Opanga amayenera kupanga mosalekeza zida zatsopano ndi matekinoloje atsopano kuti apititse patsogolo luso loletsa kusokoneza, moyo ndi kulondola kwa ma capacitive level metres kuti akwaniritse zosowa zamadera osiyanasiyana ndi ogwiritsa ntchito.

Mapeto
Paddy field capacitive level mita imagwira ntchito yofunika kwambiri paulimi wamakono. Kugwiritsa ntchito kwake pakuwunika kuchuluka kwa madzi sikungowonjezera kagwiritsidwe ntchito kabwino ka madzi, komanso kumapereka chithandizo chaukadaulo chaulimi wolondola. Ndi kupita patsogolo kwa sayansi ndi ukadaulo komanso kupita patsogolo kwaukadaulo waulimi, ma capacitive level metres apitilizabe kuchita zabwino zake kuti athandizire chitukuko chokhazikika cha ulimi wa mpunga ndikuwonjezera kupanga ndi ndalama za alimi.
