Ndi kupita patsogolo kosalekeza kwa sayansi ndi ukadaulo, kugwiritsa ntchito masensa a nthaka kukukulirakulira m'magawo a ulimi, kuteteza chilengedwe ndi kuyang'anira zachilengedwe. Makamaka, sensa ya nthaka pogwiritsa ntchito njira ya SDI-12 yakhala chida chofunikira kwambiri pakuwunika nthaka chifukwa cha makhalidwe ake ogwira ntchito, olondola komanso odalirika. Pepalali lidzayambitsa njira ya SDI-12, mfundo yogwirira ntchito ya sensa yake ya nthaka, milandu yogwiritsira ntchito, ndi zomwe zikuchitika mtsogolo.
1. Chidule cha ndondomeko ya SDI-12
SDI-12 (Serial Data Interface pa 1200 baud) ndi njira yolumikizirana deta yomwe idapangidwira makamaka kuyang'anira zachilengedwe, yomwe imagwiritsidwa ntchito kwambiri m'magawo a masensa amadzi, nyengo ndi nthaka. Zinthu zake zazikulu ndi izi:
Kugwiritsa ntchito mphamvu zochepa: Chipangizo cha SDI-12 chimagwiritsa ntchito mphamvu zochepa kwambiri munthawi yoyimirira, zomwe zimapangitsa kuti chigwiritsidwe ntchito pazida zowunikira zachilengedwe zomwe zimafuna nthawi yayitali yogwira ntchito.
Kulumikizana kwa masensa ambiri: Njira ya SDI-12 imalola masensa okwana 62 kulumikizidwa kudzera pa mzere womwewo wolumikizirana, zomwe zimathandiza kusonkhanitsa mitundu yosiyanasiyana ya deta pamalo amodzi.
Kuwerenga deta mosavuta: SDI-12 imalola kufunsira deta kudzera mu malamulo osavuta a ASCII kuti ogwiritsa ntchito azitha kusintha mosavuta komanso kukonza deta.
Kulondola Kwambiri: Masensa ogwiritsa ntchito protocol ya SDI-12 nthawi zambiri amakhala ndi kulondola kwakukulu pakuyeza, komwe kuli koyenera kafukufuku wasayansi ndi ntchito zabwino zaulimi.
2. Mfundo yogwirira ntchito ya sensa ya nthaka
Sensa ya nthaka yotulutsa SDI-12 nthawi zambiri imagwiritsidwa ntchito poyesa chinyezi cha nthaka, kutentha, EC (magetsi oyendetsera) ndi zina, ndipo mfundo yake yogwirira ntchito ndi iyi:
Kuyeza chinyezi: Zosewerera chinyezi cha nthaka nthawi zambiri zimadalira mphamvu kapena kukana. Chinyezi chikapezeka m'nthaka, chinyezi chimasintha mawonekedwe amagetsi a sensa (monga mphamvu kapena kukana), ndipo kuchokera ku kusinthaku, sensa imatha kuwerengera chinyezi cha nthaka.
Kuyeza kutentha: Zosewerera zambiri za nthaka zimaphatikiza zosewerera kutentha, nthawi zambiri ndi ukadaulo wa thermocouple kapena thermocouple, kuti zipereke deta yeniyeni ya kutentha kwa nthaka.
Kuyeza mphamvu yamagetsi: Mphamvu yamagetsi imagwiritsidwa ntchito kwambiri poyesa kuchuluka kwa mchere m'nthaka, zomwe zimakhudza kukula kwa mbewu ndi kuyamwa kwa madzi.
Njira yolumikizirana: Pamene sensa ikuwerenga deta, imatumiza mtengo woyezedwa mu mtundu wa ASCII kwa wolojekiti ya data kapena host kudzera mu malangizo a SDI-12, omwe ndi abwino kusungira ndi kusanthula deta pambuyo pake.
3. Kugwiritsa ntchito sensa ya nthaka ya SDI-12
Ulimi wolondola
Mu ntchito zambiri zaulimi, sensa ya nthaka ya SDI-12 imapatsa alimi chithandizo cha sayansi pakupanga njira zothirira poyang'anira chinyezi ndi kutentha kwa nthaka nthawi yeniyeni. Mwachitsanzo, kudzera mu sensa ya nthaka ya SDI-12 yomwe yayikidwa m'munda, alimi amatha kupeza zambiri za chinyezi cha nthaka nthawi yeniyeni, malinga ndi zosowa za madzi a mbewu, kupewa kutaya madzi moyenera, kukulitsa zokolola ndi ubwino wa mbewu.
Kuyang'anira zachilengedwe
Mu polojekiti yoteteza zachilengedwe ndi kuyang'anira chilengedwe, sensa ya nthaka ya SDI-12 imagwiritsidwa ntchito kuyang'anira momwe zinthu zoipitsa zimakhudzira ubwino wa nthaka. Mapulojekiti ena okonzanso zachilengedwe amagwiritsa ntchito masensa a SDI-12 m'nthaka yoipitsidwa kuti ayang'anire kusintha kwa kuchuluka kwa zitsulo zolemera ndi mankhwala m'nthaka nthawi yeniyeni kuti apereke chithandizo cha deta pa mapulani okonzanso.
Kafukufuku wa kusintha kwa nyengo
Pa kafukufuku wokhudza kusintha kwa nyengo, kuyang'anira chinyezi cha nthaka ndi kusintha kwa kutentha ndikofunikira kwambiri pa kafukufuku wa nyengo. Sensa ya SDI-12 imapereka deta kwa nthawi yayitali, zomwe zimathandiza ofufuza kusanthula zotsatira za kusintha kwa nyengo pa kayendedwe ka madzi a nthaka. Mwachitsanzo, nthawi zina, gulu lofufuza linagwiritsa ntchito deta ya nthawi yayitali kuchokera ku sensa ya SDI-12 kuti liwunike momwe chinyezi cha nthaka chikuyendera pansi pa nyengo zosiyanasiyana, kupereka deta yofunika kwambiri yosinthira chitsanzo cha nyengo.
4. Milandu yeniyeni
Nkhani 1:
Mu munda waukulu wa zipatso ku California, ofufuzawo adagwiritsa ntchito sensa ya nthaka ya SDI-12 kuti ayang'anire chinyezi ndi kutentha kwa nthaka nthawi yeniyeni. Famuyi imalima mitengo yosiyanasiyana ya zipatso, kuphatikizapo maapulo, zipatso za citrus ndi zina zotero. Mwa kuyika masensa a SDI-12 pakati pa mitundu yosiyanasiyana ya mitengo, alimi amatha kupeza molondola momwe chinyezi chilili m'nthaka ya muzu uliwonse wa mtengo.
Zotsatira za Kukhazikitsa: Deta yomwe yasonkhanitsidwa ndi sensa imaphatikizidwa ndi deta ya nyengo, ndipo alimi amasintha njira yothirira malinga ndi chinyezi chenicheni cha nthaka, popewa kuwononga madzi chifukwa cha kuthirira mopitirira muyeso. Kuphatikiza apo, kuyang'anira kutentha kwa nthaka nthawi yeniyeni kumathandiza alimi kukonza nthawi yothirira feteleza ndi kuletsa tizilombo. Zotsatira zake zasonyeza kuti zokolola zonse za munda wa zipatso zinawonjezeka ndi 15%, ndipo kugwiritsa ntchito bwino madzi kunawonjezeka ndi kupitirira 20%.
Nkhani yachiwiri:
Mu pulojekiti yosamalira madambo kum'mawa kwa United States, gulu lofufuza linagwiritsa ntchito zida zingapo zoyezera nthaka za SDI-12 kuti ziwunikire kuchuluka kwa madzi, mchere ndi zinthu zodetsa zachilengedwe m'nthaka ya madambo. Deta iyi ndi yofunika kwambiri poyesa thanzi la zachilengedwe la madambo.
Zotsatira za Kukhazikitsa: Kudzera mu kuyang'anira kosalekeza, zapezeka kuti pali mgwirizano wachindunji pakati pa kusintha kwa kuchuluka kwa madzi m'nthaka ya madambo ndi kusintha kwa kagwiritsidwe ntchito ka nthaka yozungulira. Kusanthula deta kunawonetsa kuti kuchuluka kwa mchere m'nthaka kuzungulira madambo kumawonjezeka nthawi ya ntchito zambiri zaulimi, zomwe zimakhudza mitundu yosiyanasiyana ya madambo. Kutengera ndi deta iyi, mabungwe oteteza zachilengedwe apanga njira zoyenera zoyang'anira, monga kuchepetsa kugwiritsa ntchito madzi aulimi ndikulimbikitsa njira zolima zokhazikika, kuti achepetse kukhudzidwa kwa chilengedwe cha madambo, motero kuthandiza kuteteza mitundu yosiyanasiyana ya zomera m'derali.

Mu kafukufuku wapadziko lonse wokhudza kusintha kwa nyengo, asayansi adakhazikitsa netiweki ya zoyezera nthaka za SDI-12 m'madera osiyanasiyana a nyengo, monga madera otentha, otentha komanso ozizira, kuti aziyang'anira zizindikiro zazikulu monga chinyezi cha nthaka, kutentha ndi kuchuluka kwa mpweya wa organic carbon. Zoyezera izi zimasonkhanitsa deta pafupipafupi, kupereka chithandizo chofunikira kwambiri cha zitsanzo za nyengo.
Zotsatira za Kukhazikitsa: Kusanthula deta kunasonyeza kuti chinyezi cha nthaka ndi kusintha kwa kutentha kunakhudza kwambiri kuchuluka kwa kaboni wachilengedwe m'nthaka pansi pa nyengo zosiyanasiyana. Zomwe zapezekazi zimapereka chithandizo champhamvu cha deta pakukonza zitsanzo za nyengo, zomwe zimathandiza gulu lofufuza kulosera molondola momwe kusintha kwa nyengo mtsogolo kungakhudzire kusungidwa kwa kaboni m'nthaka. Zotsatira za kafukufukuyu zaperekedwa pamisonkhano ingapo yapadziko lonse lapansi ndipo zakopa chidwi cha anthu ambiri.
5. Chitukuko chamtsogolo
Ndi chitukuko chachangu cha ulimi wanzeru komanso kusintha kwa zofunikira zoteteza chilengedwe, njira yamtsogolo yopititsira patsogolo masensa a nthaka a SDI-12 ikhoza kufotokozedwa motere:
Kuphatikiza kwakukulu: Masensa amtsogolo adzaphatikiza ntchito zambiri zoyezera, monga kuyang'anira nyengo (kutentha, chinyezi, kuthamanga), kuti apereke chithandizo chokwanira cha deta.
Luntha Lowonjezereka: Pogwirizana ndi ukadaulo wa Internet of Things (IoT), sensa ya nthaka ya SDI-12 idzakhala ndi chithandizo chanzeru pakupanga zisankho ndi malingaliro kutengera deta yeniyeni.
Kuwonetsa deta: M'tsogolomu, masensa adzagwirizana ndi nsanja zamtambo kapena mapulogalamu am'manja kuti akwaniritse kuwonetsa deta m'njira yowoneka bwino, kuti athandize ogwiritsa ntchito kupeza zambiri za nthaka munthawi yake ndikuchita bwino kwambiri.
Kuchepetsa mtengo: Pamene ukadaulo ukupitirira kukula ndipo njira zopangira zinthu zikukwera, mtengo wopangira masensa a nthaka a SDI-12 ukuyembekezeka kuchepa ndikupezeka kwambiri.
Mapeto
Sensa ya nthaka yotulutsa SDI-12 ndi yosavuta kugwiritsa ntchito, yothandiza, ndipo imatha kupereka deta yodalirika ya nthaka, yomwe ndi chida chofunikira chothandizira ulimi wolondola komanso kuyang'anira chilengedwe. Ndi luso lopitilira komanso kufalikira kwa ukadaulo, masensa awa apereka chithandizo chofunikira kwambiri cha deta kuti akonze bwino ulimi komanso njira zotetezera chilengedwe, zomwe zikuthandizira chitukuko chokhazikika komanso kumanga chitukuko cha chilengedwe.
