Sezvo nzanga yevanhu uye kuvandudzwa kwemaindasitiri kuri kuramba kuchienderera mberi, nyaya yekushaikwa kwemvura iri kuramba ichiwedzera.Kunatsiridza magadzirirwo emvura yemarara emumaguta uye kuwana otomatiki kudzora kunobata zvakadzama theoretical kukosha uye hunoshanda kukosha mukusimudzira marara ekurapa.Kufambira mberi uku kunobatsira mukuchengetedza mari uye kuvandudza kunaka kwezvakatipoteredza.
1.Wastewater Treatment Process
Maitiro ekugadziriswa kwemvura yetsvina anosanganisira kutanga kurapwa, biological kurapwa, uye kurapwa kwepamusoro.Mukusimudzira nekuvandudza zvidyarwa zvekuchenesa mvura yetsvina, kuvandudzwa kwetekinoroji kwakakosha.Shanduko nekusimudzira indasitiri inotsamira zvakanyanya pakuvimbiswa uye kutsigirwa kwehunyanzvi hutsva uye kufambira mberi kwehunyanzvi hwepamusoro.
2.Nyaya Yomumunda
Iyo ODOT C-Series Remote IO inoiswa munzvimbo yekuchenesa mvura yetsvina muguta riri muSichuan Province, China, sezvinotevera:
Iyo yekuchenesa mvura yetsvina inoshandisa Nokia S7-1500 seyo huru PLC, iri mukamuri yepakati yekudzora.Iyo ODOT ES-Series switch inovaka ring network, ichishandisa CN-8032-L modules sezviteshi zviri kure muzvikamu zvakasiyana-siyana zvemaitiro.Aya mamodule anofambisa kuunganidzwa kwedata uye kutonga mukati mechikamu chega chega chemaitiro kuburikidza neIO.Iyo data yakaunganidzwa inoendeswa kuPLC yepakati pekutonga kuburikidza nemhete network switch.
Zvikamu zvehurongwa zvinosanganisira:
(1) Pre-kurapa Chikamu: Ichi chikamu chinosanganisira CN-8032-L module sechiteshi chiri kure.Iyo inodzora yakaomarara uye yakanaka skrini, uye aeration inogadzirisa matangi.Remote kutanga-kumisa kutonga kwezviratidziro kunowanikwa kuburikidza neCT-121F uye CT-222F modules.Iyo aeration yekugadzirisa tangi, yakapihwa nemugadziri wemidziyo, inoratidzira 485 interface inotsigira yakajairwa Modbus RTU protocol.Kutarisisa uye kutaurirana neaeration yekumisikidza tangi kunowanikwa kuburikidza neCT-5321 module kuti ive nechokwadi chekudyidzana mashandiro nevane simba uye zviratidziro.
(2) Carbon Source Addition Chikamu: Kuti ive nechokwadi chekuteedzera yakazara nitrogen yekuburitsa zviyero, chikamu ichi chinogadzirisa chigadziriso chemvura yemushonga nekushandisa akawanda ekuyerera kwemamita uye chinja mavharuvhu.Zvakafanana nechikamu chekutanga kurapwa, chiteshi chinoshandisa CN-8032-L sechiteshi chiri kure.CT-121F uye CT-222F modules kudzora switch mavharuvhu.Iyo PNM02 V2.0 gedhi inounganidza pakarepo uye yakawedzera kuyerera data kubva masere ekuyerera kwemamita pa-saiti, ichiendesa yakananga kuPLC mushure mekubatanidzwa munetiweki yemhete.
(3) Biological Tank/Secondary Sedimentation Tangi: Aya maitiro maviri anogovera imwe chiteshi chiri kure chine CN-8032-L module.Yakaiswa CT-121F, CT-222F, CT-3238, uye CT-4234 modules midziyo yekudzora yakadai seyakadzika magitator, mukati nekunze reflux pombi mubhaibheri tank, sludge scraping machines, uye reflux pombi mune yechipiri sedimentation tank.Kuwanda kwepombi yakasara yesludge inoda kutonga zvichienderana ne-de-mud interval inodiwa;saka, variable frequency control inogamuchirwa.Iyo CT-3238 module inounganidza masaini azvino kubva kune frequency converter, nepo CT-4234 module inoburitsa 4-20mA masiginecha kudzora frequency, kufambisa chaiyo-nguva yekutarisa yeORP, yakanyungudika okisijeni, uye data yemhando yemvura.
(4) PAC Dosing Chikamu: Zvakafanana nekabhoni sosi yekuwedzera chikamu, nzvimbo iyi inosanganisira CN-8032-L sechiteshi chiri kure.Iyo inodzora otomatiki kumisikidzwa kwemushonga wemvura nekugadzirisa switch mavharuvhu uye yekutarisa kuyerera kwemamita kukosha.
(5) Fiber Filter Pool: Ichishandisa yakaparadzana hurongwa hwekugadzirisa tsvina yepamusoro, Siemens S7-1200 inoita sechinhu chikuru chekutonga.Maseti matanhatu emadziva ekusefa anodzorwa nenhanhatu CN-8032-L zviteshi, mumwe nemumwe.Izvi zviteshi zvinobata mafirita dziva masisitimu uye kutaurirana data nepakati 1500 PLC kuburikidza neS7 kutaurirana.
Pamusoro pezvo, kune zvikamu zvinotsigira maitiro senge imba yekuvhuvhuta, de-mud midziyo, deodorization michina, uye influent/effluent online monitoring.
3. Complete Solution Sumo
Imba yekufuridza inoshandisa yakazara seti yevateveri inopihwa nemugadziri wemidziyo, inotsigira Modbus-RTU yekutaurirana protocol.Nekuda kwehuwandu hwe data kubva kune mafeni, kushandisa CT-5321 slots kunorambidzwa.Naizvozvo, kune data re fan muchirongwa ichi, iyo PNM02 gedhi rinoshandiswa kuunganidza data.Inounganidza data kubva kuhuwandu hwemaseti mashanu evateveri, kubatanidza kuunganidzwa kwedata kuburikidza negedhi rimwe chete uye nekuisanganisa kune network.
Iyo yepamhepo yekutarisa chiridzwa chekupinza uye yekubuda mvura inongopa imwechete seti ye485 michina yekusangana yekutaurirana.Nekudaro, inoda kuunganidzwa panguva imwe chete nekombuta inotambira uye iyo DTU terminal.Apa ndipo panopinda yedu ODOT-S4E2 gedhi.Iyo gedhi inopa ina yakazvimirira serial ports.Serial port 1 inogadzikwa seye master chiteshi chekuunganidza data kubva kune inopinza uye yekubuda mvura yekutarisa.Serial port 2 inoita sechiteshi chepasi chinopa data kune iyo DTU mudziyo kuverenga.Panguva imwe chete, gedhi rinopa yakashandurwa Modbus TCP protocol kune komputa inotambira kuti itore data.
Nekutora nzira dzepamusoro dzekuchenesa mvura yetsvina uye tekinoroji yekudzora tekinoroji, chirimwa chekuchenesa mvura yetsvina chakawana mashandiro anoshanda, akagadzikana, uye ane hushamwari.ODOT Remote IO yakapa rutsigiro rwakasimba rwekusimudzira nekugadzirisa fekitori.Saizvozvo, kuburikidza nehunyanzvi hwekuvandudza tekinoroji uye shanduko yeindasitiri, chirimwa chekuchenesa mvura yetsvina chakaita budiriro huru mukusimudzira kushanda kwemvura yetsvina, kuchengetedza mari, uye kuvandudza kunaka kwenzvimbo.
