Kune rumwe rutivi, kuongorora magwaro pamusoro petiweki kunoratidzika kunge kuripo, asi kune rumwe rutivi, haisati yava tsika inogamuchirwa, kusiyana nekudhinda kwetiweki. Mamaneja achiri kuisa madhiraivha, uye kure kure scanning marongero ndeega ega ega scanner modhi. Ndeapi matekinoroji aripo panguva ino, uye mamiriro akadai ane remangwana here?
Mutyairi anoiswa kana kupinda kwakananga
Parizvino kune mana akajairika marudzi evatyairi: TWAIN, ISIS, SANE uye WIA. Chaizvoizvo, madhiraivha aya anoita senge interface pakati pechishandiso uye yakaderera-level raibhurari kubva kumugadziri inobatanidza kune chaiyo modhi.
Yakareruka scanner yekubatanidza architecture
Kazhinji zvinofungidzirwa kuti scanner yakabatana zvakananga kune kombiyuta. Nekudaro, hapana anoganhura iyo protocol pakati peiyo yakaderera-level raibhurari uye mudziyo. Inogonawo kuva TCP/IP. Aya ndiwo mashandiro anoita maMFP mazhinji ane network ikozvino: scanner inoonekwa seyemunharaunda, asi kubatana kunoenda kuburikidza netiweki.
Kubatsira kwemhinduro iyi ndeyekuti chikumbiro hachina basa nemazvo kuti kubatana kunoitwa sei, chinhu chikuru ndechekuona yakajairika TWAIN, ISIS kana imwe interface. Hapana chikonzero chekushandisa rubatsiro rwakakosha.
Asi zvazvakaipira zviri pachenawo. Mhinduro yacho yakavakirwa pane desktop OS. Zvishandiso zvefoni hazvichatsigirwi. Chechipiri chinokanganisa ndechekuti vatyairi vanogona kunge vasina kugadzikana pazvivakwa zvakaomarara, semuenzaniso, pamaseva ekupedzisira ane vatengi vatete.
Iyo nzira yekubuda ndeye kutsigira yakananga kubatana kune scanner kuburikidza neHTTP/RESTful protocol.
TWAIN Direct
yakakurudzirwa neTWAIN Working Group senzira yekuwana mutyairi.
TWAIN Direct
Pfungwa huru ndeyokuti pfungwa dzose dzinoendeswa kune scanner side. Uye scanner inopa mukana kuburikidza neREST API. Pamusoro pezvo, iyo yakatarwa ine tsananguro yekutsikisa mudziyo (autodiscovery). Zvinotaridzika zvakanaka. Kune maneja, izvi zvinobvisa matambudziko anogona kuitika nevatyairi. Tsigiro yemidziyo yese, chinhu chikuru ndechekuti kune inowirirana application. Kune zvakare zvakanakira mugadziri, kunyanya iyo yakajairika yekudyidzana interface. Iyo scanner inoshanda sewebhu sevhisi.
Kana tikafunga nezve mashandisiro chaiwo mamiriro, pachava zvakare nekuipira. Chekutanga ideadlock situation. Iko hakuna zvishandiso pamusika neTWAIN Direct uye hazvina musoro kuti vanogadzira vatsigire tekinoroji iyi, uye zvinopesana. Yechipiri ndeyekuchengetedza; iyo yakatarwa haiisi zvinodiwa pane manejimendi emushandisi kana kuwanda kwezvigadziriso kuvhara maburi anogona. Izvo zvakare hazvizivikanwe kuti vatungamiriri vanogona kudzora sei zvigadziriso uye kuwana. Iyo komputa ine antivirus software. Asi mune scanner firmware, iyo zviri pachena ichave newebhu server, izvi zvingave zvisiri izvo. Kana kuve, asi kwete izvo zvinodiwa nekambani yekuchengetedza mutemo. Bvumiranai, kuve nemalware ayo anotumira ese akaongororwa magwaro kuruboshwe hakuna kunaka. Ndokunge, nekuitwa kweiyi chiyero, mabasa akagadziriswa nemaseting echitatu-bato maapplication anochinjirwa kune vanogadzira zvishandiso.
Kukanganisa kwechitatu ndiko kurasikirwa kunogona kuitika kwekushanda. Vatyairi vanogona kunge vaine imwe post-processing. Barcode kuzivikanwa, kubviswa kumashure. Mamwe ma scanner ane anonzi. imprinter - basa rinobvumira scanner kuti idhindwe pagwaro rakagadziriswa. Izvi hazviwanikwe muTWAIN Direct. Iyo yakatarwa inobvumira iyo API kuti iwedzere, asi izvi zvinotungamira kune akawanda etsika kuita.
Uye imwezve minus mumamiriro ekushanda ne scanner.
Skena kubva kune application, kana scan kubva kune mudziyo
Ngatitarisei kuti yenguva dzose scan kubva kune application inoshanda sei. Ndiri kuisa gwaro pasi. Ndobva ndavhura app ndotarisa. Ndobva ndatora gwaro racho. Matanho matatu. Zvino fungidzira kuti network scanner iri mune imwe kamuri. Iwe unofanirwa kuita kanenge 2 nzira dzekuzvibata nayo. Izvi hazvisi nyore pane kudhinda netiweki.
Ndiyo imwe nyaya kana scanner pachayo inogona kutumira gwaro. Somuenzaniso, netsamba. Ndiri kuisa gwaro pasi. Ndobva nda scan. Gwaro racho rinobva rabhururuka richienda kuhurongwa hwekunangwa.
Uyu ndiwo musiyano mukuru. Kana mudziyo wakabatana kunetiweki, saka zviri nyore kuti utarise zvakananga kune yakanangwa chengetedzo: folda, tsamba kana ECM system. Hapana nzvimbo yemutyairi mudunhu iri.
Kubva pakuona kwekunze, tinoshandisa network scanning pasina kushandura tekinoroji iripo. Uyezve, zvese kubva padesktop application kuburikidza nemutyairi, uye zvakananga kubva kune mudziyo. Asi kuremesa scan kubva pakombuta hakuna kupararira sekudhinda netiweki nekuda kwekusiyana kwemaitiro ekushanda. Kutarisa zvakananga kunzvimbo yaunoda kuchengetedza kuri kuwedzera kufarirwa.
Tsigiro yeTWAIN Direct scanners sechinzvimbo chevatyairi inhanho yakanaka kwazvo. Asi chiyero chakanonoka zvishoma. Vashandisi vanoda kuongorora zvakananga kubva kunetiweki mudziyo, vachitumira magwaro kwavanoenda. Zvishandiso zviripo hazvidi kutsigira chiyero chitsva, nekuti zvese zvinoshanda zvakanaka izvozvi, uye vanogadzira scanner havafanirwe kuishandisa, sezvo pasina maapplication.
Mukupedzisa. Maitiro akajairika anoratidza kuti kungotarisa peji rimwe chete kana maviri anotsiviwa nemakamera pamafoni. Pachasara kutariswa kwemaindasitiri, uko kumhanya kwakakosha, tsigiro yemashure-ekugadzirisa mabasa ayo TWAIN Direct isingakwanise kupa, uye uko kubatanidzwa kwakasimba nesoftware kucharamba kwakakosha.
