He aha te mea COM-tauranga? Te pūrere, te whakahaere COM-tauranga

COM-tauranga, tauranga rangatū ranei ko te atanga rangatū ahungarua, kua hangaia nei mo te utu paita raraunga. Hoki te wa tuatahi, whakamahia te tauranga ki te hono i te kāpeka me ka ki te pouwhanga, me kiore. Na te noa reira whakamahia ki te hono i te supply mana uninterruptible me mo te kōrero ki te pūmārō pūnaha tukatuka rorohiko tāmau momo.

te whakamahi o

Na, i mua ia koutou kōrero atu e pā ana ki te mea he COM-tauranga, me titiro e koe ki te mua mo te māramatanga o tona tikanga. Just 15 tau ki muri, te tikanga e whakamahia ana ki te hono whakaaro ki te rorohiko mā te tūhono paerewa motuhake kei i runga i te hoki o te tahuhu te whakamahi i te rangatū RS-232 taura motuhake. He maha huakore tenei tikanga. he taura taua, i ngā paerewa hou, whakarato he auau raraunga rawa iti - e pā ana ki kotahi rau kilobits ia te rua. I tua atu, ka hanga i te hononga tinana o tūhono hiahiatia ki te whakatinana i te katinga o te taputapu, a ka piri ratou ki tetahi ki tetahi i te tikanga o te tīwiri, ki te whakarite tika, i te mea kei o ratou rahi o nui uara.

He hītori iti

COM-tauranga i runga i te ka rorohiko tuku iho kakahu te tau 1 ranei 2, kia rite ki te hunga ratou te tikanga kaua e nui ake i te rua. Ka taea e te tāuta e koe te tauranga atu ki te whakatika i te hiahia. A, no te hiahiatia te tatūnga pūmanawa kaiwhakamahi ki te karo whakama, me te tika whakaturia ko reira te kotahi e hono ki te taputapu tika. rapu Ia tautuhinga COM-tauranga te auau tika o te tuku raraunga, me te he maha o te tahi atu tawhā neherā o nei i mohiotia ki te porohita kuiti o tohunga anake. Hei hono i te taputapu ki te kia angitu, nga tawhā tika katoa e hiahiatia ana tetahi wahi ki te ako tiki ake experimentally, pera i roto i tenei take ranei, i reira ko kahore tetahi whirihoranga aunoa. I tua atu, i te hononga mā COM-tauranga ahei o honotanga tetahi pūmanawa ki tetahi taputapu waho, ara tino maiorooro, i te mea he aha i roto i te tukanga o te tautuhinga me i reira ko te rota o hapa.

hurihuri

Na hononga mā COM-tauranga rawa te mono i e atu tikanga hou, e titau kore matauranga motuhake mō te whakatinanatanga, ara i roto i te USB-tauranga. Ko kowaiwai o nga drawbacks katoa whakahuatia i mua tenei tikanga. Heoi, paerewa o nāianei hononga hototahi o nga mea katoa o te GPS-taputapu, me te pūmanawa tino heterogeneous i hanga mo te wa roa a tawhio noa te ariā o te COM-tauranga e kua riro te tawhito o nāianei.

Ko tā te te meka e tīmatanga tata tetahi taputapu, tae atu GPS, ko waho, me ona hononga ki te rorohiko whakamana e te taura rangatū hono ki tetahi o nga tauranga pūmārō. Mai i te kaiwhakamahi i roto i te tukanga whirihoranga hiahiatia ki te whiriwhiri i te tere tau tauranga me te raraunga translation tika i runga i te reira. I taua wa, i reira ko te paerewa raraunga matua i te GPS-kaiwhiwhi ki te hōtaka, ka karanga nei NMEA-0183. I roto i te meka, titau tenei paerewa ngā katoa, ara ki te pūmārō hou, me te pūmanawa ki te kōrero i roto i te COM-tauranga. Na tenei katoa i roto i te mata o te mea rorohiko hou, me te te CPC, kua roa i te nuinga i te paerewa USB. A i tetahi atu āhuatanga ko e piki e timata te tata GPS-farii ki te tāuta tika i roto i te marae e te mea tino ngaro o tetahi taura hononga ki waenganui reira me te pūrere matua.

tauranga COM Mariko

Ko te ara i roto i i whakaaro, ara ki te whakawhanake i te "mariko» COM-tauranga. Huri i te reira i roto i taua i te pūrere puriringa ā-, hei tauira, whakataruna GPS-kaiwhiwhi te i roto i te pūmanawa rite COM-tauranga, e kore ia te hunga he i roto i ngā taputapu. I roto i tenei hōtaka, kua hangaia nei hoki interfacing i roto i te paerewa rite, kahore rerekētanga pehea te whakatinana i te reira. He pea te aroaro o te whaihanga mariko, a kahore tika te aroaro o te whakatinanatanga pūmārō. Na ko reira taea ki te whakarite i te hototahi o te tauira GPS-pūmanawa tawhito ki taputapu hou.

te huringa

I te wa ano te whakahaere i te COM-tauranga e kore kua tino puta ke. Me mahi i te kaiwhakamahi tawhito tatūnga matatini tata ā. Heoi, tohu hou COM-tauranga kore whakanohoia te pūrere mōmona kei i runga i te rōpū muri o te kōwae pūnaha, me te pūrere katoa rerekē. Na reira te mea katoa, ko te e i te wāhi pūmanawa o te tirohanga, titiro katoa o ratou ite ihotaata ore, e ko, kahore he rerekētanga i waenganui i ngā tauranga mariko me tūturu. Hoki pūmanawa rerekē tau tauranga anake i roto i taua e faataahia ratou ki te kaihanga PDA ki te pūtake rawa matapōkere. Hei tauira, whakaatu ana te kaiwhiwhi o ASUS te tikanga kei runga i COM5, a PocketLOOX 560 he kaiwhiwhi mo COM8. Huri i te reira i roto i taua he hōtaka e hiahia ana ki te riro i te raraunga GPS-kaiwhiwhi e te tīmatanga kahore kōrero pono i runga i te tau tāututanga raro e puta i te tauranga, kua rēhita hoki te kaiwhiwhi hāngai i runga i tenei PDA.

He pēhea te tenei mahi katoa?

Ki taua, ka taea e koe te kawe i roto i te rapu aunoa mo te tukanga taua ruri o wātea katoa COM-tauranga e tika ana ko te tika hārakiraki, me te tino cumbersome. Ko tenei e tika ana ki te meka i te pūrere whakaaturia i roto i te pūnaha rite te COM-tauranga, e taea e rawa kanorau, me te kore e pā ana ki a GPS, ka taea e waiho ratou rawa ohorere ki te whakahoki kupu tenei rangahau. Hei tauira, te PDA ko nga tauranga e pā ana ki te pouwhanga pūtau ā, ki te USB, tauranga pōkākā, me te tahi atu āhuatanga. Te pīra ki a ratou i te hōtaka hangaia ki te mahi ki te pūrere motuhake, ka taea e arahi ki te tauhohe tino ohorere, me te ki ngā malfunctions e maha ai iri PDA. Ko Ko te aha te ngana ki te whakatuwhera i te COM-tauranga e taea arahi ki ngā āhuatanga ohorere ake ki te tahuri i runga i te Nihokikorangi ranei tauranga pōkākā. Na reira kia take atu kerekere.

Jobs COM-tauranga

Hoki COM-tauranga whakamahia te rite te pūtake mo te maramara transceiver te ao tukutahingakore. E wātea ana i roto i te maha ngā rongo tenei maramara: Intel 16550A, 16550, 16450, 8250. hoki ia COM-tauranga Kei roto te reira i te rēhita kaiwhiwhi me te tuku raraunga, me te maha o nga rēhita mana e taea te uru i roto i te BIOS, Windows me MS DOS. I roto i te putanga hou o te maramara e te huinga o ngā moka mo te pupuri poto te tuku, ka riro raraunga. Ki tenei āheinga, ka taea e koe aruaru te mahi o te PTM iti pinepine, me te ki te taunga auau raraunga o te haapurororaa.

Ko te tawhā matua

pūrere COM-tauranga riro te oraraa o taua āhuatanga āhuatanga:

- tauranga wāhitau turanga mo inputting me outputting mōhiohio;

- te tau pūmārō haukoti;

- te rahi o tetahi poraka o ngā mōhiohio;

- te tere i nei tuku raraunga te;

- aratau tapatahi rapunga;

- tikanga mana rere;

- te maha o paraire mutu.

Me pēhea te ki te tirohia i te COM-tauranga i runga i tō rorohiko? He aha ki te titiro hoki?

Ka rite ki whakahuatia mua, tenei momo o te tauranga, ko te atanga anga-rua mō te tuku raraunga ki te taumata moka i roto i te ara ōrite. Te āhuatanga motuhake i roto i te rite ki te tauranga whakarara konei ko te whakawhitinga raraunga moka i te moka. Ko taua e te rorohiko e kore ia anake whakamahi rangatū tikanga tuku raraunga COM-tauranga anatomy. Hei tauira, atanga pērā i Itarangi USB ranei, te whakamahi i hoki te parau tumu taua, engari reira na tupu mua e rangatū huaina ai tauranga RS232 paerewa.

Kei te maha hiahiatia te reira ki te whakatuwhera i COM-tauranga mo te hanga me te rorohiko tātaritanga, i te mea kei tika hoki reira ki te tirohia i runga i te mahi. Tahu huānga no te mea he reira tino māmā. e tupu tino maha meinga tenei i te kaiwhakamahi e hua pūrere momotunga he, toia te tūhono, ka hono ki te atanga. Ko te ara māmā ki te whakamatautau i te mahi atanga ko ki te hono ki taua mea ki te kiore. Heoi, he uaua tenei ki te tiki i te pikitia tino, mai whakamahi te raweke hawhe anake o nga rārangi tohu o te waru. Anake te whakamahi o te plug motuhake, me te tuku i te hōtaka ki te tirohia i te mahi. Hoki tenei whakaaro tīariari kē pūmanawa rawa whakawhanakehia.
