Nahea te kiore rorohiko

Ko tētahi o nga wae faufaa o tetahi pūnaha rorohiko hou - he kiore rorohiko. Kua roa kua tenei "kiore" he wahi o desktops kore anake, engari rorohiko hoki, ahakoa i roto i te puka paku whakarerekē.

Titiro rite te kiore rorohiko, mohio katoa. I roto i te tahi mau rave'a, te reira tino titiro rite te pōrearea pai-mohiotia, ahakoa ki etahi rahuitia. Kei te whakapono te reira e kore te mea kitea whakatupuranga heke mai o ngā kaiwhakamahi o tenei rōpū. Ahakoa, ki te anake te mea piki whakamana kiore rorohiko hou ahokore, tangohia o te "hiku".

Ko te parau tumu o te mahi o tenei pūrere ko ohie tino maere: ka te oho ai ki runga ki te mata o taunga whanaunga e tuku ki te rorohiko, te wahi e tahuri pūmanawa motuhake ki te kaupapa pehu i runga i te atatohu mata. He aha te mea ngā, e kore ai e anake reira te pere mua o te pūnaha whakahaere, engari ano hoki he pūāhua i roto i te kēmu rorohiko. Muri te tapatahi kitea huna te mahi o Engineers, hiko Engineers me hötaka. Tei runga i te hanganga o te kiore rorohiko āhuatanga kia whai rerekē kaupapa rēhita. Kia mahara tatou he aha te mea te rerekētanga i waenganui i enei whakaaro huru ōrite.

puta te tauira tuatahi 50 tau ki muri, i reira i aunoa. Roto te pūrere ko te pōro whakarewa nui pani ki te apa o te rapa. Te taha raro, ka haere mai ia i roto i te whakapā atu ki te mata waho, me te tahi atu e rua - ki te awa. i taea kua ratou tokowha, engari i tukatuka rua anake. A, no te neke koe i te ringa e pupuri ana i te pōro kiore okeoke haere i a ratou rārangi - te pana, me ka i puta ki te raupapa o tohu hiko e kua tonoa ki te rorohiko. E rua awa he rawaka mō te fariiraa i te pūwāhi fakafekau'aki i runga i te waka rererangi. Ko te āhuatanga o tenei otinga ngā te hiahia mō te pōro wā horoi i piri paru (huruhuru hau piri puehu) me te whakakapinga o ngā wāhanga tawhito.

I maoro i whakakapi ratou e rongoā optical-aunoa. Waho, e noho tonu nga mea katoa, engari kua whakakorea nga whakakā, whakakapia e te otinga atu pakari - optocoupler. Hoki te "nanakia" te ingoa huna LED rawa te kinokore, me te pūoko whatu, tuku ngātahi te ki hono i rite Opto. ngā ia takai i ki te wira pūwatawata whakaritea i waenganui i te pūoko me te ngōhiko. A, no te tītaka te awa kurupae arumanga i tuhia e te pūoko ka tuku ki te rorohiko. E matau te auau neke "matapihi / taiepa", ko reira taea ki te whakatau i te tere me te ahunga o te kaupapa.

I 1999, i reira nga kiore rorohiko taketake, ka karanga optical, i roto i nei whakahaere te tikanga pūkaha o kaupapa tuhi ki te tino hoatu ki runga. LED turama te mata i raro i te kiore, me te kāmera tahito ki etahi auau hanga whakapakoko. Ko te kōwae pūtukatuka kakau ratou i runga i te pūtake o te hua mutunga e te tere me te ahunga o te displacement. Ka taea e tatou te whakawhiti noa i te hōtaka atekōkiri raraunga.

I maoro i whakakapi ratou e taiaho whakarerekē. riro te pūtukatuka kua atu hua, arotahi kua nui haere tika, "raruraru" papa ki runga ki e kore e te pūoko mahi, kua riro tata. Ko te rerekētanga matua i te tahi atu momo whatu arahina, e tuku hoki kore kitea, a pōkākā. E te ara, te kiore rorohiko tino utu - ko reira he taiaho. Heoi, tona utu tiketike (neke atu i te 24 mano tāra) he tika mihiwai matua mea kakano whakauru, e kore ngā āhuatanga hangarau.
