Kuyika Chipangizo
Kuyika kukula kwa chipangizo kukuwonetsedwa mu Chithunzi 1.Choyamba, gwedezani pamtunda woyenera wa khoma, ikani bolt yowonjezera, kenaka mukonze.
Chithunzi 1: Kupanga Chipangizo
Waya wotulutsa wa relay
Kuchuluka kwa gasi kukadutsa pachiwopsezo chowopsa, cholumikizira mu chipangizocho chimayatsa/kuzimitsa, ndipo ogwiritsa ntchito amatha kulumikiza chida cholumikizira monga fan.Chithunzi chojambulidwa chikuwonetsedwa mu Chithunzi 2.Kulumikizana kowuma kumagwiritsidwa ntchito mkati mwa batri ndipo chipangizo chiyenera kulumikizidwa kunja, tcherani khutu ku ntchito yotetezeka ya magetsi ndipo samalani ndi kugwedezeka kwa magetsi.
Chithunzi 2:Wchithunzi chofotokozera cha relay
Zogwirizana ndi RS485
Chidacho chimatha kulumikiza chowongolera kapena DCS kudzera pa basi ya RS485.
Zindikirani: RS485 linanena bungwe mode mawonekedwe amadalira zenizeni.
1. Ponena za njira yochizira ya chishango chosanjikiza cha chingwe chotetezedwa, chonde chitani kugwirizana komaliza.Ndibwino kuti chishango chomwe chili kumapeto kwa wolamulira chigwirizane ndi chipolopolo kuti chisasokonezedwe.
2. Ngati chipangizocho chili kutali, kapena ngati zipangizo zambiri zimagwirizanitsidwa ndi basi ya 485 panthawi imodzimodzi, tikulimbikitsidwa kuti muyike 120-euro terminal resistor pa chipangizo chothandizira.
Chidacho chili ndi mabatani a 6, chophimba cha LCD, zida za alamu zogwirizana (magetsi a alamu, buzzer) akhoza kuwerengedwa, kukhazikitsa magawo a alamu ndikuwerenga zolemba za alamu.Chidacho chokha chimakhala ndi ntchito yosungiramo zinthu, yomwe imatha kulemba ma alarm ndi nthawi mu nthawi yeniyeni.Pazochita zinazake ndi magwiridwe antchito, chonde onani kufotokozera pansipa.
