1. Chidule cha Akuluakulu
Kuti muwone bwino ubwino wa madzi m'chitsime chozama, njira yolumikizirana ya 4G sensing system monga RD-ETTSP-01 yophatikizidwa ndi Pneumatic Water Gauge ndiyo muyezo wamakampani. Yankho la magawo 5 ili limayesa nthawi imodzi Electrical Conductivity (EC), TDS, Salinity, Temperature, ndi Liquid Level. Pogwiritsa ntchito electrode ya PTFE yosagwira dzimbiri ndi gateway ya 4G/LoRaWAN, ogwiritsa ntchito amatha kutumiza deta yeniyeni kuchokera ku kuya kwa 10m+ kupita ku ma seva amtambo. Njira yomanga iyi imatsimikizira magwiridwe antchito okhazikika m'malo opangira acidic kapena okhala ndi mchere wambiri komwe ma transducers achikhalidwe ndi ma electrodes wamba nthawi zambiri amalephera.
2. Chifukwa Chake PTFE Electrodes Imachita Bwino Mu Zinyalala Zazikulu Zamakampani
Kutengera zaka 15 zomwe takhala tikupanga ma IoT node a mafakitale, tapeza kuti ma electrode wamba amawonongeka mofulumira m'malo ozama omwe ali ndi mchere wambiri kapena madzi otuluka m'mafakitale. RD-ETTSP-01 imathetsa izi kudzera muKapangidwe ka ma elekitirodi a PTFE (Polytetrafluoroethylene), zomwe zimapereka kukana kosayerekezeka kwa ma acid, alkali, ndi njira zothetsera mchere wambiri.
Chidziwitso cha Zomangamanga:Kuphatikizika kwa EC probe ndi Pneumatic Water Gauge mu bracket yolumikizirana kumalola kuti pakhale malo ocheperako, ofunikira kwambiri pa zitsime za mainchesi 4 kapena 6. Mosiyana ndi ma transducers achikhalidwe omwe amatha kuipitsa m'zitsime zamatope, Pneumatic Gauge imagwiritsa ntchito sensing yapakati pa gasi kuti ipereke mulingo wolondola wa 0.2% popanda kukhudzana mwachindunji ndi madzi ndi ma diaphragm amkati osavuta. Dziwani: Gauge iyi ndi yoyenera gasi kapena madzi aliwonse omwe sawononga chitsulo chosapanga dzimbiri.
3. Mafotokozedwe Aukadaulo & Deta Yoletsa Kulephera
Deta yotsatirayi ikuwonetsa kukonza kwa digito kokhazikika kwambiri komwe kwaphatikizidwa mu mndandanda wathu wa masensa a 2025.

4. Kukonza Kasamalidwe ka Madzi Ochokera M'madzi ...
Mu ntchito zathu zogawa madzi, kusinthasintha kwa ubwino wa madzi ndi kusintha kwa milingo nthawi yeniyeni kumalola kuti pakhale chitsanzo cha aquifer. Dongosololi limathandizira ma backhaul ambiri opanda zingwe:
•GPRS/4G/WiFi:Zabwino kwambiri pamasamba omwe ali ndi ma cellular coverage omwe alipo kale.
•LoRa/LoRaWAN:Zabwino kwambiri poyang'anira za m'nyanja zakutali kapena magulu a zitsime zakuya komwe chipata chimodzi chimasonkhanitsa deta kuchokera ku ma node angapo (mpaka 300m pa node iliyonse).
•Kuwonetsa Zinthu pa Mtambo:Ma seva athu odzipereka amapereka ma dashboards enieni komanso kupeza deta yakale, monga momwe tawonera mu ma node athu owunikira zam'madzi.
5. Zochitika Zogwiritsira Ntchito Zamakampani
| Zachilengedwe ndi za Municipal | Zamalonda ndi Mphamvu | Chakudya ndi Ulimi |
| • Kuwunika kwa Paintaneti pa Kusamalira Zinyalala | • Madzi Oziziritsira Mphamvu Yotentha | • Ulimi wa Nsomba Wochuluka Kwambiri |
| • Kugawa Madzi Abwino Pampopi | • Kupangira zitsulo ndi ma elekitiroma | • Kulamulira Njira Yopangira Kuphika |
| • Kutsata Mchere wa Madzi Pamwamba | • Kutaya Madzi M'makampani a Mankhwala | • Kukonza Chakudya ndi Kupanga Mapepala |
| • Kusindikiza ndi Kupaka Nsalu | • Machitidwe Obwezeretsa Asidi/Alkali | • Kusanja Zakudya za Hydroponic |
6. Kukhazikitsa Katswiri: Kupewa Cholakwika cha "Dead Cavity"
Mainjiniya nthawi zambiri amanyalanyaza momwe madzi amayendera mozungulira sensa. Kuti musunge miyezo ya EEAT pakuyika kwanu, tsatirani njira izi:
1.Pewani "Mabowo Akufa":Mu mapaipi kapena pansi pa madzi, onetsetsani kuti cholumikizira cha electrode sichitali kwambiri poyerekeza ndi chowonjezeracho. Ngati probe yaikidwa mozama kwambiri mu cholumikizira chopapatiza, madzi amakhalabe osasuntha. "Dead Cavity" iyi imatanthauza kuti sensa yanu ikuyesa madzi akale, zomwe zimapangitsa kuti deta ichedwe kwambiri komanso zolakwika zichitike.
2.Kuchotsa Kuchulukana kwa Gasi:Pakuyika mapaipi, onetsetsani kuti chitolirocho chadzaza. Ma thovu a mpweya kapena matumba a gasi m'chipinda choyezera angayambitse kusakhazikika, kulumpha.
3.Kupatula Zizindikiro:Chizindikiro choyezera ndi chizindikiro chamagetsi chofooka.Chingwe chopezera chiyenera kuyendetsedwa payekha.Musamaiphatikize ndi zingwe zamagetsi zamphamvu kapena zingwe zowongolera; kusokoneza kumatha kuwononga gawo loyezera la mita.
4.Ukhondo wa Electrode:Musakhudze malo a electrode ndi manja opanda kanthu. Mafuta otsala pakhungu amaletsa kukhudzana kolondola kwa ma ion ndi ma electrode, zomwe zimapangitsa kuti kuwerengera kusakhale kothandiza.
7. Mafunso Ofunsidwa Kawirikawiri
Q1: Kodi ndingatani kuti ndizitha kuyeza sensa ngati kuwerengako kukuyenda?
A:Kulinganiza kumaphatikizapo kusintha "Electrode Constant" kudzera mu Modbus. Choyamba, ikani constant kukhala 1.0 (0×03 E8). Yesani yankho lokhazikika (monga, 1413 µS/cm). Ngati kuwerenga kuli kolakwika pang'ono, sinthani linear multiple (monga, kukhala 0.98 kapena 0×03 E6) kuti igwirizane ndi muyezo.
Q2: Kodi sensayi ikhoza kupulumuka zinyalala zamafakitale zokhala ndi asidi wambiri?
A:Inde. Kugwiritsa ntchito electrode ya PTFE ndi chitsulo chosapanga dzimbiri choyezera mpweya kumathandizira kuti ma acid ambiri a mafakitale ndi ma alkali asagwere. Komabe, pewani kukanda electrode mwamakina poyeretsa, chifukwa izi zimasintha electrode yokhazikika.
Q3: Kodi kutalika kwa chingwe kungasinthidwe kuti kugwiritsidwe ntchito m'zitsime za 50m+?
A:Zingwezo ndi zapadera, zotetezedwa, komanso zokhazikika ku fakitale. Ngakhale kuti mulingo woyenera ndi 10m, kutalika kuyenera kufotokozedwa panthawi yoyitanitsa kuti zitsimikizire kuti fakitale ikulinganiza bwino. Kusintha zingwezo m'munda ndi waya wosagwiritsidwa ntchito kungayambitse zolakwika zazikulu pakuyeza.
Q4: Kodi ndingabwezeretse bwanji adilesi ya chipangizo "chotayika"?
A:Ngati adilesi ya Modbus yayiwalika, gwiritsani ntchito adilesi yowulutsa0XFEDziwani kuti host iyenera kulumikizidwa ndi kapolo mmodzi yekha pogwiritsa ntchito lamuloli kuti mufunse kapena kubwezeretsanso adilesi yoyambirira.
