Chitsanzo chogwiritsira ntchito cha mafakitale a Ethernet switch in power industry (I)

Wanzeru substation monitoring system/power station yogawa makina owongolera

1. Dongosolo lanzeru loyang'anira kagawo kakang'ono

Dongosolo lanzeru loyang'anira pa intaneti la substation limazindikira kugawana zidziwitso, kulumikizana kwadongosolo, mawonekedwe a zida, kuyang'anira chandamale, kusungitsa zidziwitso zapaintaneti, kukhazikika kwa protocol yolumikizirana, kuyang'anira magwiridwe antchito, kuphatikiza zidziwitso, kusonkhanitsa zenizeni zenizeni za zida. pa siteshoni, kusanthula kwatsatanetsatane kwa matenda ndi kuwunika kwa moyo wonse. Kumbali imodzi, njira yowunikira ya substation ndi njira yodziyimira payokha yolumikizira zida zosinthira zida zamkati, kumbali ina, ndi gawo la telecontrol master station, yomwe imatumiza kuwunika ndi kuzindikira kwa zida zamkati zamkati ndi udindo wake. zambiri ku master station.

Changfei Photoelectric Industrial Ethernet SwitchMu njira yanzeru yowunikira ma substation system, kuwunika kwa A ndi B kwapawiri-network, gawo loyang'anira masiteshoni ndi makina osanjikiza awiri-gawo limodzi la netiweki amatengedwa, ndipo siteshoni yonse imakhala ndi netiweki imodzi pansi, ndi kusiyana kwa basi. Njira yodumphira mwachindunji imasinthidwa, ndipo njira yolumikizira netiweki yolumikizira imatengedwa. Kuyang'anira maukonde apawiri a A ndi B kumatsimikizira kukhazikika komanso kusagwira ntchito kwa kapezedwe ka data. Chigawo chachitetezo ndi zida zophatikizira zida zanzeru za IED zimalumikizidwa mwachindunji ndi chosinthira kapena chitetezo ndi kuyeza ndi zida zowongolera, kenako zimatumizidwa kumalo owongolera masiteshoni kudzera pa network ya A ndi B yapawiri kuti alumikizane ndi ma seva, makamu oyang'anira, telecontrol. malo ogwirira ntchito ndi malo owongolera akutali, kuti muzindikire kuphatikiza zidziwitso ndikuwongolera kutali kwa siteshoni yonse.

2, Makina owongolera ogawa amagetsi

Malo opangira magetsi ndiye gwero lamagetsi amtundu wamagetsi amtundu wamagetsi, ndipo kupanga makina opangira magetsi ndi luntha kwakhala mayendedwe a anthu. Distributed control system (DCS) yakula mwachangu kuyambira pomwe idawonekera pakati pazaka za m'ma 1970. Pofuna kupititsa patsogolo chitukuko cha digito ndi chidziwitso m'mafakitale amagetsi, pang'onopang'ono muzindikire deta ndi chidziwitso cha dongosolo la DCS ndikutsatira mfundo ya kayendetsedwe kabwino, kukhazikitsidwa kwa kufala kwa Ethernet ndizochitika zazikulu pakukula kwa kayendetsedwe ka mafakitale ndi makina. mlingo mu zomera mphamvu.

Gawo la data access layer limapachikidwa pa gawo la I/O la DCS kudzera pa seva yosinthira mawonekedwe, yomwe imatha kupanga mapu a data kumunda ku chidziwitso cha data pa basi ya I/O ya DCS, kuti chidziwitso chowongolera cha DCS chiphatikizidwe. mofanana. Njira yolumikizirana ndi data imatengera mawonekedwe amtundu wa ring ring network wopangidwa ndi 1 # ndi 2 # mayunitsi a main control system. Uplink imalumikiza malo ogwirira ntchito, malo opangira mainjiniya ndi ma seva ogwiritsira ntchito kudzera pa Changfei Gigabit Industrial Ethernet switch CF-HY4T8024S-SFP, ndipo downlink imalumikiza malo owongolera ndi oyang'anira kudzera pa Gigabit Industrial Ethernet switch CF-HY2008GV-SFP. Masamba onse a netiweki amatengera mawonekedwe onse a netiweki ya mphete zosanjikiza ziwiri, masamba a I/O atha kukulitsidwa motsika. Zindikirani dongosolo la redundancy la dongosolo lonse ndikuwonetsetsa kudalirika ndi kukhazikika kwa kutumiza deta.
