Kuti igadziriswe negirinhi uye simba idzva, OSB yakanga yagadzira PV magetsi inverter yekupisa pombi R32.
Iyo inokwanisa kusimba neDC simba kubva kuPv panhi, zvakare inoshanda neAC simba kubva grid.
Kunze kweWIFI remote control, kune Rs485 control iripo.
Chii chinonzi RS485 kudzora chaungabvunza.
RS485 chiyero chinotsanangura maitiro emagetsi emitsara ye serial yekushandiswa mune serial yekutaurirana masisitimu. Icho chinonyanya kuita chimiro che serial communication. Zvinogona kunzwika zvakaoma kune avo vasingazive chii chinonzi serial kutaurirana, isu tine chokwadi chekuti unogona kuwana mhinduro muchinyorwa.
Zvino chii chinonzi serial communication?
Serial kutaurirana inzira yekutumira data. Zvakafanana neUniversal Serial Bus (USB) kana ethernet yatinogona kuwana mumakomputa edu mazhinji emazuva ano. Zvivakwa zvekugadzira zvinoshandisa serial kutaurirana kubatanidza zvishandiso zvavo pamwechete. Sezvambotaurwa, muenzaniso we serial kutaurirana ndeye RS485.
. Kukurukurirana kweseri zvakare kune hunhu hwekutsikisa kudzivirira kudhumhana kwemapaketi edata, zvichiita kuti ive yakavimbika kune yekubatanidza system ine akawanda maturusi. Pakupedzisira, inogona kufungidzirwa nenzira yekuti serial kutaurirana kunoitwa zvakanyanya kune iyi kushandiswa kana ichienzaniswa neyakajairika USB.
Kune akasiyana serial ekutaurirana zviyero seRS232, RS422 uye RS485. Iyo inonyanya kushandiswa kutaurirana mwero ndeye RS232.
RS485 inoshandiswa mumakomputa mazhinji uye otomatiki masisitimu. Mimwe yemienzaniso marobhoti, zviteshi zvepasi, madhiraivha, vhidhiyo yekutarisa uye zvakare midziyo yemumba. Mumakomputa masisitimu, RS485 inoshandiswa kufambisa data pakati pemutongi uye dhisiki drive. Makabati endege dzekutengesa anoshandisawo RS485 kune yakaderera-speed data communications. Izvi zvinokonzerwa neiyo shoma wiring inodiwa nekuda kweiyo wiring configuration zvinodiwa zveRS485.
Saka neiyo RS485 kudzora, inogona kuve yakawanda mushandisi hushamwari uye kusangana neakawanda kudzora kure kudiwa.
Bata nesu izvozvi kuti uwane rumwe ruzivo.
