borris_ Posted February 12, 2012 Share Posted February 12, 2012 Prikaci I phone na tu stangu u autobusu i vidjeces da poslije sedam dana nece vise raditi. U industriji imas hiljadu normi koje obicni aparati nemaju. Ne znam ih sada na pamet ali svaki aparat koji treba da se implementira u voz/tramvaj/autobus treba biti izgradjen po posebnim normama da bi mogao izdrzati svakodnevne napore (vibracija, prasina, frekvencija upotrebe itd itd) i da se ne pokvari za mjesec ili manje dana.

Skyhighatrist Posted February 12, 2012 Share Posted February 12, 2012 iPhone ima production price od 200$, i ima trista džirlo kuraca palaca koje validator nema. Kao što rekoh, ovome je najjači feature neka jebačka plastika, koju nije (baš) lako polomiti, sve druge iznutrice zaista nisu nikakav high-tech, čak i za uslove celodnevnog drmusanja po beogradskim sokacima... Možda sam i jako u krivu, ali sumnjam... Link to comment
fonTelefon Posted February 12, 2012 Share Posted February 12, 2012 Još jednom, ne košta sistem 12m, oni bi za tu cifru odmah prodali ceo sistem i trljali ruke. Možemo da nagađamo i izvodimo računice koliko sistem zaista košta, ali sumnjam da sve na gomilu košta više od 3-4m (plus održavanje)...zna li se ko je potpisao gurao sve ovo? idealno za pranje para.

Nije nesto tehnoloski napredan, nema "touch screen" ali je "rugged design". Link to comment
Matilda Ivancic Posted February 12, 2012 Share Posted February 12, 2012 pa posto je onda ono plasticno sediste za bus, 1000 evra? Link to comment
borris_ Posted February 12, 2012 Share Posted February 12, 2012 Treba samo da shvatite da cijene nisu iste kada su u pitanju obicni aparati za smrtnike (ti aparati se i prave da traju sto manje) i industrijski aparati. Link to comment

borris_ Posted February 12, 2012 Share Posted February 12, 2012 Imama hiljadu takvi primjera, nemoj da trazim sada.Raspitacu se koliko kostaju RATP bus validatori koji izgledaju ovako: Link to comment
Kelt Posted February 12, 2012 Share Posted February 12, 2012 nego, jel se samo meni čini ili validacija traje predugo? Link to comment
Skyhighatrist Posted February 12, 2012 Share Posted February 12, 2012 (edited) Raspitacu se koliko kostaju RATP bus validatori koji izgledaju ovako: U trku za 15 sekundi kod žute braće: 100$nego, jel se samo meni čini ili validacija traje predugo?Negde i dalje uopšte ne prolazi, negde traje daleko više nego što su rekli (beše sekund po čoveku), a negde fakat traje manje od sekunde, ali ako meriš vreme od momenta kad nasloniš karticu - znači ništa ulazak, stajanje, kretanje, muvanje, ovaj te gradi, onaj ti smeta, još neko izlazi... Kad bi se stvarno validiralo samo dok se stoji u stanici, red vožnje bi mogao da ispoštuje samo poluprazan bus... Edited February 12, 2012 by historian Link to comment
borris_ Posted February 12, 2012 Share Posted February 12, 2012 RATP ne kupuje kod zute brace. Link to comment
Valk Posted February 12, 2012 Share Posted February 12, 2012 da li to ''rugged design'' znači da je predviđeno da preživi, recimo, ako tenk pređe preko? Link to comment
borris_ Posted February 12, 2012 Share Posted February 12, 2012 (edited) Pa vidio sam neke propagandne filmove za aparate koji rade i kada pucas u njih.Ruggedcom na primjer ima najoptornije switche-ove ali su zato oko 20% skuplji od odastalih (koji su isto rugged design). sada vidjeh da ih je kupio siemens Edited February 12, 2012 by borris_ Link to comment
Skyhighatrist Posted February 12, 2012 Share Posted February 12, 2012 RATP ne kupuje kod zute brace.Ne znam za RATP, ali ne bih stavio ruku u vatru za mešovito tursko/srpsko preduzeće <_< Al' nevermind, čak i da validatori koštaju 300$, sve su ih platili od prvog meseca. Uopšte se ne bojim za njihovu zaradu, osim ako srpski inat ne pobedi (švercovanje u sličnim razmerama kao i do sada)... Link to comment
