Icyiciro kimwe cy'ingufu zingana na 485

 

Imetero imwe yingufu zingufu hamwe na rs485 nigisekuru gishya cya metero ntoya yubumenyi bwamashanyarazi yatangijwe nisosiyete yacu, ikoresha uburambe bwimyaka mugushushanya metero yamashanyarazi. Uru ruhererekane rwa metero rwemeza - ibisobanuro byerekanwe LCD yerekanwe hamwe na interineti ya RS485 kugirango itahure amakuru nyayo - igihe cyo guhanahana amakuru hamwe na mudasobwa yo hejuru, bigafasha gusoma metero ya kure (hamwe numurimo wo kugenzura kure kugirango ufungure / uzimya kandi ibikorwa byubushake bwa remarge yishyurwa mbere). Yorohereza cyane gucunga mu buryo bwikora bwo gukoresha amashanyarazi.

Igishushanyo cya Wiring:Terminal 1 - 4 yubwoko bwashizwe kurukuta ni kubitanga amashanyarazi no gukoresha imizigo (1 na 2 ihuza L wire, 3 na 4 ihuza N wire, ihujwe nu mutwaro); itumanaho 9-12 ni imikorere yimikorere (9: Impanuka nziza, 10: Impanuka mbi, 11: 485A, 12: 485B).

Kwirinda Kwishyiriraho:Gukoresha insinga bigomba kwerekeza ku gishushanyo mbonera cy’uruhande rwa metero, kandi birasabwa gukoresha insinga z'umuringa kugirango zihuze; kuri metero - ihuza, tandukanya icyerekezo cyinjira n’isohoka, kandi komeza imigozi kugirango wirinde guhura nabi gutera metero zidasanzwe.

Ibikurikira nuburyo bwo gutembera kwa metero imwe yingufu zingana na rs485.
Gutanga amasoko no kugenzura
Kugura ibice byingenzi nka potentiometero, shunts na LCD yerekana; Mugaragaza ibice byujuje ubuziranenge binyuze mubigenzurwa no kugerageza imikorere kugirango urebe neza ibikoresho fatizo.

Ubuyobozi bwa PCB Gukora no gusudira
Gukora imbaho ​​za PCB ukurikije igishushanyo mbonera; ibice byo gusudira ukoresheje SMT (Surface Mount Technology); nyuma yo kurangiza, kora abagurisha hamwe kugenzura kugirango ugurishe ubukonje bukonje nibibazo byabacuruzi babuze, urebe neza ko imiyoboro yumuzunguruko.

Inteko n'Ikizamini Cyambere
Kusanya imbaho ​​za PCB, casings, terminal hamwe nibindi bice mubicuruzwa byarangiye; kora imbaraga - mugupima kwambere kugirango urebe niba LCD yerekana nibikorwa byibanze byo gupima nibisanzwe, no gukuraho ibicuruzwa nibikorwa bidasanzwe.

Kugenzura neza no kugerageza gusaza
Koresha amashanyarazi asanzwe kugirango uhindure neza metero kugirango wuzuze ibisabwa mu cyiciro cya 1.

Igenzura rya nyuma no gupakira
Kora igenzura rya nyuma kubicuruzwa byujuje ibisabwa mu gusaza, harimo kugenzura isura, kugenzura imikorere no kugenzura ibipimo; andika ibicuruzwa byujuje ibisabwa hamwe nibicuruzwa bipfunyitse kugirango urebe ko nta byangiritse mugihe cyo gutwara.
