Pamene chikhalidwe cha anthu ndi ntchito zamakono zikupita patsogolo, nkhani ya kusowa kwa madzi ikukulirakulira.Kukonza njira zoyeretsera madzi akumatauni ndikukwaniritsa kuwongolera pawokha kumakhala ndi tanthauzo laukadaulo komanso phindu lothandizira pakupititsa patsogolo kukonza bwino kwa madzi onyansa.Kupita patsogolo kumeneku kumathandizira kupulumutsa ndalama komanso kuwongolera chilengedwe.
1.Njira Yochizira Madzi Onyansa
Njira yoyeretsera madzi oipa imaphatikizapo chithandizo choyambirira, chithandizo chamankhwala, ndi chithandizo chapamwamba.Pakukweza ndi kukonzanso malo osungira madzi oipa, luso laukadaulo ndilofunika kwambiri.Kusintha ndi kukweza kwa makampani kumadalira kwambiri chitsimikizo ndi chithandizo cha matekinoloje atsopano ndi kupita patsogolo kwapamwamba.
2.Nkhani Yakumunda
The ODOT C-Series Remote IO ikugwiritsidwa ntchito m'malo oyeretsera madzi oipa mumzinda wa Sichuan Province, China, motere:
Malo opangira madzi onyansa amagwiritsa ntchito Siemens S7-1500 monga PLC yayikulu, yomwe ili m'chipinda chapakati chowongolera.Kusintha kwa ODOT ES-Series kumapanga nsanja ya netiweki ya mphete, pogwiritsa ntchito ma module a CN-8032-L ngati masiteshoni akutali m'magawo osiyanasiyana amachitidwe.Ma modulewa amathandizira kusonkhanitsa ndi kuwongolera deta mkati mwa gawo lililonse la ndondomeko kudzera mu IO.Zomwe zasonkhanitsidwa zimatumizidwa ku PLC kuti ziwongoleredwe pakatikati kudzera pa ring network switch.
Zigawo za ndondomekoyi zikuphatikizapo:
(1) Gawo lachisamaliro: Gawoli lili ndi gawo la CN-8032-L ngati siteshoni yakutali.Imawongolera zowonera zowoneka bwino komanso zowoneka bwino, komanso matanki okhazikitsa mpweya.Kuwongolera koyambira kwakutali kwa zowonera kumatheka kudzera ma module a CT-121F ndi CT-222F.Tanki yokhazikitsira mpweya, yoperekedwa ndi wopanga zida, imakhala ndi mawonekedwe a 485 othandizira protocol ya Modbus RTU.Kuyang'anira ndi kulumikizana ndi thanki yokhazikitsira aeration kumatheka kudzera mu module ya CT-5321 kuwonetsetsa kuti magwiridwe antchito ndi okhudzidwa ndi zowonera.
(2) Gawo Lowonjezera la Mpweya wa Mpweya: Kuti zitsimikizire kutsatiridwa kwa miyezo yonse ya nayitrogeni yotulutsa, gawoli limakonza madzi amadzimadzi pogwiritsa ntchito ma flowmeter angapo ndi ma valve osinthira.Mofanana ndi gawo la chithandizo chisanachitike, siteshoniyi imagwiritsa ntchito CN-8032-L ngati malo akutali.CT-121F ndi CT-222F modules control switch valves.Chipata cha PNM02 V2.0 chimasonkhanitsa nthawi yomweyo komanso kuchulukana kwa data kuchokera pamamita asanu ndi atatu oyenda pamalopo, ndikutumiza mwachindunji ku PLC pambuyo pophatikizana ndi netiweki ya mphete.
(3) Biological Tank/Secondary Sedimentation Tank: Njira ziwirizi zimagawana siteshoni imodzi yakutali yokhala ndi gawo la CN-8032-L.Zokwera CT-121F, CT-222F, CT-3238, ndi CT-4234 zida zowongolera ma modules monga ma agitators omira, mapampu amkati ndi akunja a reflux mu thanki yachilengedwe, makina opukutira a sludge, ndi mapampu a reflux mu thanki yachiwiri ya sedimentation.Kuchuluka kwa pampu yotsalira ya sludge kumafunika kuwongolera malinga ndi zomwe zimafunikira nthawi ya de-matope;motero, kuwongolera pafupipafupi kumatengedwa.Module ya CT-3238 imasonkhanitsa zizindikiro zamakono kuchokera ku frequency converter, pamene CT-4234 module imatulutsa zizindikiro za 4-20mA kuti ziwongolere mafupipafupi, kuthandizira kuyang'anira nthawi yeniyeni ya ORP, mpweya wosungunuka, ndi deta yamadzi.
(4) Gawo la PAC Dosing: Mofanana ndi gawo lowonjezera la carbon source, derali limaphatikizapo CN-8032-L ngati siteshoni yakutali.Imawongolera masinthidwe amadzimadzi amadzimadzi poyang'anira ma valavu osinthira ndikuyang'anira mayendedwe a mita.
(5) Fiber Filter Pool: Pogwiritsa ntchito njira yodzilamulira yodzipangira mankhwala apamwamba a zimbudzi, Siemens S7-1200 imakhala ngati chipangizo chachikulu chowongolera.Magawo asanu ndi limodzi a maiwe osefera amayendetsedwa ndi masiteshoni asanu ndi limodzi a CN-8032-L, payekhapayekha.Masiteshoni awa amayendetsa machitidwe a dziwe losefera ndikulumikizana ndi data ndi chapakati 1500 PLC kudzera pakulankhulana kwa S7.
Kuphatikiza apo, pali magawo othandizira monga chipinda chowombera, zida zochotsera matope, zida zochotsera fungo, komanso kuwunika kowoneka bwino pa intaneti.
3. Mawu Omaliza Oyankha
Chipinda chowombera chimagwiritsa ntchito mafani athunthu operekedwa ndi wopanga zida, amathandizira njira yolumikizirana ya Modbus-RTU.Chifukwa cha kuchuluka kwa data kuchokera kwa mafani, kugwiritsa ntchito mipata ya CT-5321 ndikoletsedwa.Chifukwa chake, pa data ya mafani mu pulojekitiyi, chipata cha PNM02 chimagwiritsidwa ntchito posonkhanitsa deta.Imasonkhanitsa deta kuchokera kumagulu asanu a mafani, kuphatikiza zosonkhanitsa deta kudzera pachipata chimodzi ndikuziphatikiza pa intaneti.
Chida chowunikira pa intaneti chamadzi olowera ndi kutulutsa chimangopereka zida za 485 zolumikizirana.Komabe, ikuyenera kusonkhanitsidwa nthawi imodzi ndi kompyuta yolandila ndi terminal ya DTU.Apa ndipamene chipata chathu cha ODOT-S4E2 chimayamba kuseweredwa.Chipatachi chimapereka madoko anayi odziyimira pawokha.Seri port 1 imayikidwa ngati malo otsogola osonkhanitsira deta kuchokera ku chowunikira chamadzi cholowera ndi kutulutsa.Serial port 2 imagwira ntchito ngati siteshoni yocheperako yomwe imapereka chidziwitso cha chipangizo cha DTU kuti chiwerenge.Panthawi imodzimodziyo, chipatacho chimapereka protocol ya Modbus TCP yosinthidwa kuti makompyuta omwe ali nawo atengere deta.
Potengera njira zapamwamba zoyeretsera madzi akunyansidwa ndi matekinoloje owongolera okha, malo oyeretsera madzi oyipa achita bwino, okhazikika, komanso osakonda chilengedwe.ODOT Remote IO yapereka chithandizo champhamvu pakukweza ndi kukonzanso fakitale.Nthawi yomweyo, pogwiritsa ntchito luso laukadaulo komanso kusintha kwamakampani, malo opangira madzi oyipa achita bwino kwambiri pakuwongolera bwino madzi akuwonongeka, kupulumutsa ndalama, komanso kukonza chilengedwe.
Ndizo zonse za mtundu uwu wa #ODOTBlog.Tikuyembekezera kugawana kwathu kotsatira!
