uqhagamshelwano

Ewe, sinemitha yamandla ye-IoT eza ne-RS485/4G/LoRa. Kwaye sinikezela ngesango elilumkileyo lokudibanisa naluphi na uhlobo lweemitha zamandla eModbus ukuqokelela idatha kunye nokutyhala idatha kwilifu.
Sinesoftware yelifu kwinguqulelo yesiTshayina, kwaye iLifu limiselwe eTshayina. Sicebisa ukuba ucwangcise isoftware yakho, kwaye usebenzise izixhobo zethu zehardware.

Imilinganiselo yamandla engafanelekanga inokubangelwa liqela lezinto, kubandakanywa izicwangciso zendlela yokulinganisa engalunganga, iimpazamo zeengcingo, ukhetho olungafanelekanga kunye nezicwangciso ze-transformer, kunye nokukhethwa kokunikezelwa kwamandla okungalunganga.
Khangela imo yokulinganisa imo yokulinganisa: imo yokulinganisa ihlulwe ibe yimilinganiselo yokudibanisa i-angular kunye nokulinganisa ukudibanisa kweenkwenkwezi, iindlela ezahlukeneyo zokulinganisa, kukho iindlela ezahlukeneyo zokulinganisa. umlinganiselo.
Qinisekisa ukuba i-wiring ichanekile: Yenza uxhulumaniso njengoko kubonisiwe kwidayagram yocingo, kubandakanywa nokuqinisekisa ukuba izigaba ezithathu kunye nezikhokelo zokuhamba kwe-transformer zangoku zihlala zifana, zilandela iintolo ezibonisa indlela yokuhamba ukusuka kumthombo ukuya kumthwalo.
Khangela ukhetho kunye nokumiselwa kwe-transformer: i-transformer efanelekileyo kufuneka ikhethwe ngokoluhlu olulinganisiweyo, kwi-transformer yangoku, xa ixabiso langoku langoku lingaphantsi kwe-5% yexabiso elilinganisiweyo langoku le-transformer, ukulinganisa okungalunganga kuya kwenzeka. Ngexesha elifanayo, umlinganiselo obekwe kwisixhobo kufuneka uhambelane nokukhethwa kwangempela kweenguqu.
Jonga unikezelo lwamandla: Qinisekisa ukuba iimitha kunye nezinye izixhobo zokulinganisa zisebenzisa unikezelo lwamandla olufanelekileyo ukunqanda iimpazamo ezibangelwa kukungonelanga kombane.

Xa i-wiring, ingqalelo kufuneka ihlawulwe kulandelelwano lwe-wiring. I-shunt ayihlulwanga kwiipali ezilungileyo kunye nezibi, kodwa imitha yamandla kufuneka ifakwe ngokunyamekela ukukhusela umonakalo kwisixhobo ngokuguqula i-wiring.
Ezinye izinto ezixhathisayo, ezibandakanya kodwa zingaphelelanga kwii-breaker circuits, switches, light bulbs, njl., azivumelekanga kwisiphaluka esiqhagamshelwe kwi-shunt ukukhusela i-voltage loops enokonakalisa imitha.
Ngaphantsi kokusebenza ixesha elide, eyona nto ikhoyo inconywa ukuba ingadluli i-80% ye-current rated current.
Imitha kufuneka ifakwe kunye ne-shunt kwibhokisi enye, ngaphandle koko iya kuchaphazela ukuchaneka kokulinganisa.

Iziphazamiso zonxibelelwano lwemitha zohlulwe zibe ziindidi ezimbini,ixesha elide kunye nethutyana.
Kuqala jonga useto lweparameter, qinisekisa ukuba iiparameters zemitha (idilesi, ireyithi yebhaud, njl.njl.) kunye neeparameters ezibekwe ngumamkeli wekhompyuter ziyahambelana enye kwenye, kwaye emva koko uvavanye ukuba kukho ixabiso lombane malunga ne-2V phakathi konxibelelwano. amazibuko, esetyenziselwa ukumisela imeko yamacandelo axhathisayo kwisekethe yonxibelelwano.
Ukuba unxibelelwano oluphakathi aluqhelekanga, qwalasela ukhetho lwentambo.
Ukhetho oluchanekileyo lwentambo kunye nocingo:
Ngentambo yeentambo ezimbini, izibuko lonxibelelwano liqhagamshelwe nje kwi-port ye-computer ye host host.
Ngekhebula le-conductor emithathu, i-port yonxibelelwano ixhunywe kwi-port yonxibelelwano yekhompyutheni yomninimzi, kwaye i-terminal eqhelekileyo ixhunyiwe kwi-GND yekhompyutheni yokusingatha.
