    Chiyambi cha malonda

    Kodi mawonekedwe a RS-485 ndi chiyani? Kodi mawonekedwe ake ndi otani poyerekeza ndi mawonekedwe a RS-232-C? Chifukwa cha mawonekedwe oyambirira a mawonekedwe a RS-232-C, pali zolephera zina, makamaka kuphatikizapo mfundo zinayi zotsatirazi: (1) Chidziwitso cha mawonekedwe a mawonekedwe ndi apamwamba, chomwe chiri chosavuta kuwononga chip cha dera la mawonekedwe. , ndipo chifukwa sizigwirizana ndi mlingo wa TTL, m'pofunika kugwiritsa ntchito mlingo kutembenuka dera kulumikiza ndi TTL dera. (2) Mlingo wotumizira ndi wotsika. Pakutumiza kwa asynchronous, kuchuluka kwa baud ndi 20Kbps. (3) Mawonekedwewa amagwiritsira ntchito mzere wa chizindikiro ndi mzere wobwereranso chizindikiro kuti apange mawonekedwe ofanana opatsirana pansi. Kupatsirana kwapansi kumeneku kumakonda kusokoneza wamba, kotero kukana kusokoneza phokoso kumakhala kofooka. (4) Mtunda wotumizira ndi wochepa. Mtengo wokhazikika wamtunda wautali wotumizira ndi 50 mapazi, koma ukhoza kugwiritsidwa ntchito pafupifupi mamita 50. Poganizira zofooka za RS-232-C, mawonekedwe atsopano a mawonekedwe atulukira, ndipo RS-485 ndi imodzi mwa izo. Ili ndi zizindikiro zotsatirazi: 1. Makhalidwe a magetsi a RS-485: logic "1" imayimiridwa ndi kusiyana kwa magetsi pakati pa mizere iwiri monga + (2-6) V; Mfundo "0" imayimiridwa ndi kusiyana kwa magetsi pakati pa mizere iwiriyo kukhala-(2-6) V. Mulingo wa chizindikiro cha mawonekedwe ndi otsika kuposa RS-232-C, kotero sikophweka kuwononga chip cha mawonekedwe ozungulira, ndipo mulingo uwu umagwirizana ndi mulingo wa TTL, womwe ungathe kulumikizidwa mosavuta ndi dera la TTL. 2. Mtengo wapamwamba kwambiri wotumizira deta wa RS-485 ndi 10 MB PS3. Mawonekedwe a RS-485 ndi ophatikizira oyendetsa bwino komanso olandila osiyanitsa, omwe amathandizira kusokoneza kosagwirizana ndi wamba, ndiko kuti, kusokoneza kusokoneza phokoso ndikwabwino. 4. Mtengo wokhazikika wa mtunda wothamanga kwambiri wa mawonekedwe a RS-485 ndi 4,000 mapazi, omwe amatha kufika mamita 3,000. Kuphatikiza apo, mawonekedwe a RS-232-C amangololedwa kulumikiza transceiver imodzi pa basi, ndiye kuti, kuthekera kwa siteshoni imodzi. Mawonekedwe a RS-485 amalola kulumikizana kwa ma transceivers opitilira 128 m'basi. Ndiko kuti, ili ndi mphamvu ya masiteshoni ambiri, kuti ogwiritsa ntchito athe kukhazikitsa maukonde a zida pogwiritsa ntchito mawonekedwe amodzi a RS-485. Mawonekedwe a RS-485 ndi mawonekedwe omwe amakonda kwambiri chifukwa cha kusokoneza kwake koletsa phokoso, mtunda wautali wotumizira komanso kuthekera kokhala ndi masiteshoni ambiri. Chifukwa maukonde a theka-duplex wopangidwa ndi ma RS485 amangofunika mawaya awiri okha, ma RS485 amalumikizana onse amatengera kufalikira kwa awiri opotoka. Soketi ya pulagi ya 9-core ya DB-9 imagwiritsidwa ntchito pa cholumikizira cha RS485, DB-9 (bowo) imagwiritsidwa ntchito polumikizana ndi anzeru terminal RS485, ndipo DB-9 (pini) imagwiritsidwa ntchito pa kiyibodi mawonekedwe RS485 olumikizidwa ndi kiyibodi.
