Inqanaba elinye lemitha yamandla kunye ne-rs485 sisizukulwana esitsha semitha yamandla ombane amancinci aphehlelelwe yinkampani yethu, efumana iminyaka yamava kuyilo lweemitha zombane. Olu luhlu lweemitha luthatha inkcazo ephezulu{2}}yomboniso weLCD ocandekileyo kunye nojongano lonxibelelwano lweRS485 ukuqonda lokwenyani{4}}utshintshiselwano lwexesha kunye neekhompyuter eziphezulu, ukwenza ufundo lweemitha ezikude (kunye nomsebenzi wolawulo olukude lokucima/ukucima kunye nomsebenzi onganyanzelekanga wokutshaja ohlawulelwa kude). Iququzelela kakhulu ulawulo oluzenzekelayo lokusetyenziswa kombane.

Ukufakela kunye neeNcingo
Umzobo wocingo:Izitishi 1{1}}4 zohlobo olunyuswe eludongeni zezombane kunye neengcingo zokulayisha (i-1 kunye ne-2 idibanisa kwi-L wire, i-3 kunye ne-4 idibanisa kwi-N wire, iqhagamshelwe ngokuthe ngqo kumthwalo); iitheminali 9-12 ziitheminali zokusebenza (9: Pulse Positive, 10: Pulse Negative, 11: 485A, 12: 485B).
Amanyathelo okuFakela:I-wiring kufuneka ibhekiselele kumzobo we-wiring ye-physical side ye-meter, kwaye kucetyiswa ukuba kusetyenziswe i-copper connectors ukuxhuma; ngokuthe ngqo-iimitha zoqhagamshelo, yahlula phakathi kwezalathiso zengcingo ezingenayo neziphumayo, kwaye uqinise izikrufu ukunqanda ukudibanela okulambathayo ekubangeleni ukusebenza kwemitha engaqhelekanga.
Ukuhamba kweNkqubo yeMveliso
Oku kulandelayo yinkqubo yokuhamba kwemitha yamandla yesigaba esinye nge-rs485.
Ukuthengwa kweCandelo kunye noHlolo
Ukuthengwa kwezinto ezingundoqo ezifana nee-potentiometers, i-shunts kunye neziboniso ze-LCD; isikrini samacandelo afanelekileyo ngokuhlolwa kwenkangeleko kunye novavanyo lokusebenza ukuqinisekisa umgangatho wezinto ezikrwada.
PCB Board Manufacturing and Welding
Ukuvelisa iibhodi zePCB ngokoyilo lwesekethe; izixhobo ze-weld usebenzisa i-SMT (i-Surface Mount Technology); emva kokugqitywa, qhuba uhlolo oludibeneyo lwe-solder ukujonga i-solder ebandayo kunye nemiba ye-solder elahlekileyo, ukuqinisekisa ukuqhutyelwa kwesiphaluka.
INdibano kunye noVavanyo lokuQala
Hlanganisa iibhodi ze-PCB, ii-casings, iitheminali kunye namanye amacandelo kwiimveliso ezigqityiweyo; ukuqhuba amandla -kuvavanyo lokuqala ukujonga ukuba umboniso weLCD kunye nemisebenzi yokulinganisa isisiseko yesiqhelo, kwaye uphelise iimveliso ezinomsebenzi ongaqhelekanga.
Ukuchaneka koCalibration kunye noVavanyo lokuguga
Sebenzisa izixhobo ezisemgangathweni zokulinganisa umbane ukulinganisa ukuchaneka kwemitha ukuhlangabezana neemfuno zokuchaneka koDidi loku-1.
Ukuhlolwa kokugqibela kunye nokuPakisha
Ukuqhuba uhlolo lokugqibela kwiimveliso ezifanelekileyo kuvavanyo lokuguga, kubandakanywa nokuhlolwa kwenkangeleko, ukuvavanya kwakhona umsebenzi kunye nokuqinisekiswa kweparameter; ileyibhile iimveliso ezifanelekileyo kunye neemveliso zepakethe ukuqinisekisa ukuba akukho monakalo ngexesha lokuthutha.
