Kuti ikhale yosinthika ndi mphamvu zobiriwira komanso zatsopano, OSB idapanga PV power inverter heat pump R32.
Zomwe zimatha kugwiritsa ntchito mphamvu ya DC kuchokera pagulu la Pv, komanso zimagwira ntchito ndi mphamvu ya AC kuchokera ku gridi.
Kupatula kuwongolera kwakutali kwa WIFI, pali zowongolera za Rs485 zomwe zikupezeka.
Kodi kuwongolera kwa RS485 ndi chiyani komwe mungafunse.
RS485 ndi muyezo womwe umatanthawuza mawonekedwe amagetsi a mizere ya serial kuti agwiritsidwe ntchito pamakina olumikizirana. Kwenikweni ndi njira yolumikizirana mosalekeza. Zitha kumveka zovuta kwa iwo omwe sadziwa kuti ndi chiyani kulumikizana kosalekeza, tili otsimikiza kuti mutha kupeza yankho m'nkhaniyi.
Ndiye kodi serial communication ndi chiyani?
Kuyankhulana kwa seri ndi njira yotumizira deta. Zili ngati Universal Serial Bus (USB) kapena ethernet yomwe tingapeze m'makompyuta athu ambiri amakono. Zopangira zopangira zimagwiritsa ntchito kulumikizana kwa serial kulumikiza zida zawo palimodzi. Monga tanenera, chitsanzo cha serial communication ndi RS485.
. Kuyankhulana kwa seri kumakhalanso ndi machitidwe otsimikiza kuti apewe kugunda kwa mapaketi a data, ndikupangitsa kuti ikhale yodalirika pamakina olumikizirana ndi zida zambiri. Pamapeto pake, zitha kuganiziridwa mwanjira yomwe kulumikizana kwa serial kumapangidwira kugwiritsa ntchito uku poyerekeza ndi USB wamba.
Pali njira zosiyanasiyana zoyankhulirana monga RS232, RS422 ndi RS485. Njira yolumikizirana yomwe imagwiritsidwa ntchito kwambiri ndi RS232.
RS485 imagwiritsidwa ntchito pamakompyuta ambiri komanso makina opangira makina. Zina mwazitsanzo ndi maloboti, masiteshoni oyambira, zoyendetsa magalimoto, kuyang'anira makanema komanso zida zapakhomo. M'makompyuta, RS485 imagwiritsidwa ntchito potumiza deta pakati pa olamulira ndi disk drive. Makabati a ndege zamalonda amagwiritsanso ntchito RS485 pamayendedwe otsika kwambiri. Izi ndichifukwa cha mawaya ochepa omwe amafunikira chifukwa cha mawaya ofunikira a RS485.
Chifukwa chake ndi chiwongolero cha RS485, itha kukhala yabwino kwa ogwiritsa ntchito ndikukwaniritsa zofuna zakutali.
Lumikizanani nafe pompano kuti mumve zambiri.
