kuonana - PILOT

Ehe, isu tine IoT simba mita iyo inouya neRS485/4G/LoRa. Uye isu tinopa yakangwara gedhi rekubatanidza chero mhando yeModbus magetsi metres kuunganidza data uye kusundira data kune gore.
Isu tine software yegore muChinese vhezheni, uye Cloud yakamiswa muChina. Isu tinokurudzira kuti uronge yako software, uye uchishandisa yedu hardware.

Zviyero zvisina kunaka zvesimba zvinogona kukonzerwa nehuwandu hwezvinhu, zvinosanganisira zvisizvo zvekuyeresa modhi marongero, zvikanganiso zvewaya, zvisina kukodzera kusarudzwa kweshanduro uye zvigadziriso, uye kusarudzwa kwemagetsi kwakashata.
Tarisa maitiro ekuyera maitiro: chiyero chekuyera chakakamurwa kuita angular yekubatanidza kuyerwa uye kuyerwa kweyeredzi yekubatanidza, nzira dzakasiyana dzekuyera, kune nzira yekuyera yakasiyana.Kana iyo chaiyo wiring nzira isingaenderane nemagadzirirwo ari pachiridzwa, ichatungamira kune isina kururama. kuyerwa.
Iva nechokwadi chokuti wiring yakarurama: Ita zvisungo sezvinoratidzwa padhiyagiramu yewaya, kusanganisira kusimbisa kuti matatu-phase uye ikozvino transformer inoyerera mafambiro anoramba akafanana, achitevera miseve inoratidza kuyerera kubva kunobva kunobva kumutoro.
Chengetedza kusarudzwa uye kugadzika kweshanduro: shanduko yakakodzera inofanira kusarudzwa maererano nehuwandu hwakayerwa, nokuda kweshanduko yemazuva ano, apo kukosha kwezvino kwakaderera kudarika 5% yehuwandu hwemazuva ano hwekushandura, kuyerwa kusina kururama kuchaitika. Panguva imwecheteyo, chiyero chakaiswa pachiridzwa chinofanira kuenderana nesarudzo chaiyo yevashanduri.
Tarisa magetsi ekupa: Ita shuwa kuti metres nezvimwe zvekuyeresa zvishandiso zvinoshandisa zvine musoro magetsi kudzivirira kukanganisa kunokonzerwa nekusakwana kwemagetsi.

Kana wiring, kutarisa kunofanira kubhadharwa kune kutevedzana kwe wiring. Iyo shunt haina kukamurwa kuita matanda akanaka uye asina kunaka, asi mita yemagetsi inofanirwa kuve newaya nekuchenjerera kudzivirira kukanganisa kumidziyo nekudzoreredza wiring.
Zvimwe zvinodzivirira zvinosanganisirwa, zvinosanganisira asi zvisingaganhurirwe kune zvinotyora dunhu, ma switch, magirobhu emwenje, nezvimwewo, zvinorambidzwa mudunhu rakabatana neshunt kudzivirira zvishwe zvemagetsi zvinogona kukanganisa mita.
Pasi pekushanda kwenguva refu, ikozvino chaiyo inokurudzirwa kuti isapfuure 80% yezvinotarwa ikozvino.
Iyo mita inofanirwa kuiswa ne shunt mubhokisi rimwechete, kana zvisina kudaro ichakanganisa kurongeka kwekuyera.

Meter kutaurirana anomalies akakamurwa kuita mhando mbiri, yakarebesa uye inopindirana Kana mita ikatadza kutaurirana zvakajairwa kwenguva yakareba, dambudziko rekuisa parameter uye kukuvara kwechikamu kunopihwa pamberi.
Kutanga tarisa marongero eparameta, simbisa kuti ma paramita emamita (kero, baud rate, nezvimwewo) uye ma paramita akaiswa nekombuta inotambira anowirirana, wozoyedza kana paine voltage kukosha inosvika 2V pakati pekutaurirana. ports, iyo inoshandiswa kuona mamiriro ezvinhu ezvipikisi zvinopikisa munharaunda yekukurukurirana.
Kana iyo yepakati kutaurirana isina kujairika, funga nezve kusarudzwa kwetambo.
Kururamisa tambo kusarudzwa uye wiring:
Netambo yewaya mbiri, chiteshi chekutaurirana chinongobatana nechiteshi chekukurukurirana chekombuta.
Iine matatu-conductor tambo, chiteshi chekutaurirana chakabatana nechiteshi chekutaurirana chekombuta inotambira, uye iyo yakajairika terminal yakabatana neGND yekombuta inotambira.
