Nzira yekukurukurirana inzira iyo vanhu vaviri vari kutaura vese vanoshanda pamwe chete kana kutumira mameseji.
1. Simplex, hafu-duplex uye yakazara-duplex kutaurirana
Pakutaurirana-ku-point, zvinoenderana negwara uye hukama hwenguva yekufambiswa kwemeseji, iyo nzira yekutaurirana inogona kukamurwa kuita simplex, hafu-duplex, uye yakazara-duplex kutaurirana.
(1) Kukurukurirana kwakareruka kunoreva maitiro ekushanda umo mameseji anogona kungofambiswa munzira imwe chete, sezvakaratidzwa mumufananidzo 1-6 (a).
Saka rimwe remapato maviri ekutaurirana rinogona kutumira chete uye rimwe rinogona kugamuchira chete, sekutepfenyura, telemetry, remote control, wireless paging, zvichingodaro.(2) Half-duplex communication inoreva nzira yekushanda iyo mapato maviri ari mukukurukurirana anogona kutumira uye kugamuchira mameseji, asi kwete panguva imwe chete, sezvinoratidzwa mumufananidzo 1-6 (b).Semuenzaniso, wakajairika walkie-talkies anoshandisa yakafanana mutakuri frequency, kubvunza uye kudzoreredza, nezvimwe.
(3) Yakazara-duplex (Duplex) kutaurirana kunoreva nzira yekushanda umo mapato ese ari maviri anogona kutumira uye kugamuchira meseji panguva imwe chete.Kazhinji kutaura, chiteshi chekutaurirana kwakazara-duplex kunofanirwa kunge kuri bidirectional chiteshi, sezvakaratidzwa mumufananidzo 1-6 (c).Runhare muenzaniso wakajairika wekutaurirana kwakazara, uko mapato ese ari kufona anogona kutaura nekuteerera panguva imwe chete.Izvo zvakafanana ndezvechokwadi kune-high-speed data kutaurirana pakati pemakombiyuta.
2.Parallel transmission uye serial transmission
Kukurukurirana kwedata (kunyanya kutaurirana pakati pemakomputa kana imwe dhijitari terminal michina), zvinoenderana neakasiyana nzira dzekufambisa dzezviratidzo zve data.Ivo vanogona kukamurwa kuita parallel kutapurirana uye serial kutapurirana.
(1) Parallel transmission ndiko kuunganidzwa kwematanho maviri kana anopfuura anoenderana anofambisa dhijitari zviratidzo zvinomiririra ruzivo panguva imwe chete.Semuyenzaniso, kutevedzana kwechiratidzo chebhinari kunosanganisira "0" uye "1" inotumirwa nekombuta inogona kufambiswa panguva imwe chete pa n parallel chiteshi nenzira yen zviratidzo paboka.Nenzira iyi, n zviratidzo mupaketi zvinogona kutamiswa kubva kune chimwe chishandiso kuenda kune chimwe mukati mewachi imwe chete.Semuenzaniso, 8-bit mavara anogona kufambiswa nenzira yakafanana uchishandisa 8 chiteshi, sezvakaratidzwa muFigure 1-7.
Chakanakira chekufambisa chakafanana ndechekuti inochengetedza nguva yekufambisa uye inokurumidza.Izvo zvakashata ndezvekuti n mitsara yekukurukurirana inodiwa uye mutengo wakakwirisa, saka inowanzo shandiswa kutaurirana kwenguva pfupi pakati pemidziyo, sekufambisa data pakati pekombuta neprinta.
(2) Serial transmission ndeyekutumira nhevedzano yezviratidzo zvedhijitari pachiteshi nenzira yakatevedzana, chiratidzo nechiratidzo, sezvakaratidzwa mumufananidzo 1-8.Iyi nzira inowanzo shandiswa kune kureba dhijitari kutapurirana.
Zviri pamusoro apa ndicho chinyorwa "Data transmission mode of communication mode" yakaunzwa kwauri neShenzhen HDV phoelectron Technology Co., Ltd. tariro iyi chinyorwa chinogona kukubatsira kuti uwedzere ruzivo rwako.Kunze kwechinyorwa ichi kana iwe uchitsvaga yakanaka optical fiber yekutaurirana michina yekugadzira kambani yaungafunganezvedu.
Shenzhen HDV phoelectron Technology Co., Ltd. inonyanya kugadzira zvigadzirwa zvekutaurirana.Parizvino, midziyo inogadzirwa inovhara iyoONU series, Optical module series, OLT series,uyetransceiver series.Isu tinogona kupa masevhisi akagadziridzwa kune akasiyana mamiriro.Unogamuchirwaconsult.
