Epulazini elikhulu laseCentral Valley yaseCalifornia, uguquko lwezolimo oluqhutshwa ubuchwepheshe lwenzeka buthule. Ipulazi elikhulu lendawo, i-Golden Harvest Farms, lisanda kwethula ubuchwepheshe benzwa yomhlabathi i-RS485 ukuqapha idatha ebalulekile efana nomswakama wenhlabathi, izinga lokushisa kanye nosawoti ngesikhathi sangempela, ngaleyo ndlela kuzuze ukuchelela okunembayo nokongiwa kwamanzi ngendlela efanele.
I-Central Valley yaseCalifornia ingenye yezindawo ezibaluleke kakhulu zokukhiqiza ezolimo e-United States, kodwa ukuqhubeka kwesomiso nokushoda kwamanzi eminyakeni yamuva kulethe izinselele ezinkulu kwezolimo zendawo. I-Golden Harvest Farm itshala izitshalo zenani eliphezulu ezihlukahlukene, ezihlanganisa ama-alimondi, amagilebhisi notamatisi. Ukubhekana nesimo esinzima samanzi, abalimi banqume ukusebenzisa ubuchwepheshe bokuzwa umhlabathi iRS485 ukuze kuthuthukiswe ukunisela nokunciphisa ukumosheka kwamanzi.
Inzwa yenhlabathi ye-RS485 iyinzwa yokunemba okuphezulu esekelwe kumgomo wokuxhumana we-RS485 ongaqoqa idatha yenhlabathi ngesikhathi sangempela futhi iyidlulisele ohlelweni lokulawula olumaphakathi ngenethiwekhi enezintambo. Abalimi bangabuka bekude izimo zenhlabathi ngomakhalekhukhwini noma amakhompyutha, futhi balungise izinhlelo zokunisela ngokusekelwe kudatha ukuze baqinisekise ukuthi izitshalo zikhula ngaphansi kwezimo ezifanele.
UMichael Johnson, umphathi wezokusebenza kweGolden Harvest Farm, uthe: “Izinzwa ze-RS485 zenhlabathi ziyishintshe ngokuphelele indlela esinisela ngayo. Esikhathini esidlule, besingahlulela kuphela ukuthi kufanele sinisele nini ngokusekelwe kokuhlangenwe nakho, kodwa manje sesingakwazi kahle ukuthi inhlabathi ngayinye idinga amanzi angakanani.
Ngokwemininingwane yasemapulazini, ngemva kokusebenzisa izinzwa zomhlabathi ze-RS485, ukusetshenziswa kwamanzi okunisela kwehliswe ngo-30%, isivuno sezitshalo senyuke ngo-15%, futhi usawoti womhlabathi uye walawulwa ngempumelelo, ukugwema ukuwohloka kwenhlabathi okubangelwa ukuchelela ngokweqile.
Ochwepheshe bezoLimo eNyuvesi yaseCalifornia, uDavis bakubona kakhulu lokhu. ULisa Brown, uprofesa eSikoleni Sesayensi Yezolimo Nezemvelo kule nyuvesi, waphawula: “Izinzwa ze-RS485 ziyithuluzi elibalulekile lokulima ngendlela enembile.
Isipiliyoni esiyimpumelelo se-Golden Harvest Farm sithuthukiswa ngokushesha e-California nakwezinye izifundazwe zezolimo. Abalimi abaningi sebeqala ukunaka futhi basebenzise ubuchwepheshe bokuzwa umhlabathi iRS485 ukuze babhekane nezinselelo ezikhulayo zemithombo yamanzi.
"Inzwa yenhlabathi ye-RS485 ayigcini nje ngokusisiza ukuthi silondoloze izindleko, kodwa futhi isivumela ukuthi sivikele kangcono imvelo," kusho uJohnson. “Sikholwa wukuthi lobu buchwepheshe buzoba wumgogodla wentuthuko yezolimo esikhathini esizayo.”
Mayelana nenzwa yomhlabathi ye-RS485:
Inzwa yenhlabathi ye-RS485 iyinzwa enembayo ephezulu esekelwe kuphrothokholi yokuxhumana ye-RS485 engaqapha idatha ebalulekile njengomswakama wenhlabathi, izinga lokushisa kanye nosawoti ngesikhathi sangempela.
Inzwa yenhlabathi ye-RS485 idlulisela idatha kusistimu yokulawula emaphakathi ngenethiwekhi enezintambo, isiza abasebenzisi ukuthi bathole ukuchelela okunembayo nokonga amanzi ngendlela efanele.
Inzwa yenhlabathi ye-RS485 ifanele izimo ezihlukahlukene ezifana nezolimo zasensimini, ukutshalwa kwe-greenhouse, ukuphathwa kwensimu yezithelo, futhi isebenza kahle ikakhulukazi ezindaweni ezomile.
Mayelana nezolimo zaseMelika:
I-United States ingumkhiqizi omkhulu wezolimo kanye nomdayisi wezolimo, futhi ezolimo zingenye yezinsika zayo ezibalulekile kwezomnotho.
I-Central Valley yaseCalifornia iyindawo yokukhiqiza yezolimo ebaluleke kakhulu e-United States, edume ngokutshala izitshalo zenani eliphezulu njengama-alimondi, amagilebhisi, notamatisi.
Ezolimo zaseMelika zigxile ekusungulweni okusha kwesayensi nezobuchwepheshe futhi zamukela ngenkuthalo ubuchwepheshe bezolimo obunembayo ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza kanye nokusetshenziswa kwezinsiza.
