Ikibazo cya tekiniki yanyuma yo gukemura ikibazo cya ODOT Automation

Mu nganda, hashobora kubaho ibibazo byinshi bishobora kuvuka, kandi uburyo bwiza bwo kwishyiriraho nuburyo bwo gukoresha insinga nibyingenzi mukurinda umutekano mubikorwa.Binyuze mu bushakashatsi bwakozwe uyu munsi, tuzareba hamwe uburyo bwo kubungabunga umutekano mu musaruro w’inganda.
1. Ibisobanuro by'ikibazo
Umukiriya wa terefone yakoreshaga module 485 y'itumanaho CT-5321 kugirango itumanaho hamwe na inverter ya frequency.Bahuye nikibazo amakarita atandatu yitumanaho muri inverter yumuriro yatwitse bikurikiranye.Nyuma yo gusimbuza amakarita ya inverter inshuro esheshatu (buri gihe bikavamo umunaniro), module y'itumanaho CT-5321 ubwayo yatwitse kumunsi wa gatandatu.

Kugira ngo hirindwe igihombo cy’abakiriya, abajenjeri ba ODOT basuye urubuga kugirango bafashe mugukemura ibibazo.

2. Kurubuga rwo gukemura ibibazo
Nyuma yo kwitegereza no gusesengura neza na ba injeniyeri ku rubuga, hagaragaye ibibazo bikurikira:

（1） Hano hari akabati 14 yo kugenzura kurubuga, buri kimwe kirimo inverter ebyiri zikoreshwa na metero imwe yingufu zikeneye kuvugana na CT5321.

（2） GND ya frequency inverter ihujwe no gukingira umurongo wumurongo wibimenyetso.

.

（4 wire Umugozi ukingiwe umurongo wa signal ya RS485 ntabwo uhujwe nubutaka.

（5 resist Kurwanya itumanaho rya RS485 ntabwo bihujwe.
3. Tera Isesengura
Ukurikije kwitegereza no gusesengura uko ibintu bimeze, injeniyeri yatanze ubushishozi bukurikira:

（1 components Ibice byangiritse hamwe na modul ntabwo byagaragaje ibimenyetso byangiritse bisanzwe bisohora amashanyarazi (ESD) cyangwa kwiyongera.Bitandukanye na ESD cyangwa ibyangiritse byangiritse, mubisanzwe ntabwo bivamo ibice byahiye, ibice byahiye muri CT-5321 byari bifitanye isano nicyuma cyo kurinda icyambu cya RS485.Iki gikoresho mubisanzwe gifite DC yameneka ya voltage ya 12V.Kubera iyo mpamvu, hafashwe umwanzuro ko voltage kuri bisi ya RS485 yarenze 12V, bishoboka ko byatewe no gutangiza amashanyarazi 24V.

（2 bus Bisi RS-485 yari ifite ibikoresho byinshi bifite ingufu nyinshi na metero zingufu.Mugihe hatabayeho kwigunga no guhagarara neza, ibyo bikoresho birashobora gukora itandukaniro rikomeye.Iyo iri tandukaniro rishobora kuba ningufu ari byinshi, birashoboka gukora umurongo kumurongo wibimenyetso RS485, biganisha ku gusenya ibikoresho kuruhande.

4. Igisubizo
Mu gusubiza ibyo bibazo biri kurubuga, abajenjeri ba ODOT batanze ibisubizo bikurikira:

1

（2 round Kuramo ibikoresho bya inverter, gutandukanya ubutaka bwerekana ibimenyetso, kandi urebe neza ko bihagaze neza.
（3） Ongeraho abarwanya itumanaho rya RS485.
（4） Shyira inzitizi za RS-485 ku bikoresho kuri bisi ya RS-485.

5. Igishushanyo cyo gukosora

Ishyirwa mu bikorwa ryingamba zo gukosora rirashobora gukumira neza ibibazo nkibi bitazongera kubaho, byemeza inyungu numutekano byabakiriya.

Muri icyo gihe, ODOT iributsa kandi abakiriya kwita ku bibazo bisa mu gushushanya no gufata neza sisitemu y’itumanaho, gushimangira kubungabunga no gucunga ibikoresho, no kwemeza umutekano no kwizerwa bya sisitemu.
