Chiyambi: Kuvuta kwa Luntha la Madzi

Mu zomangamanga zamakono zamafakitale, kuyang'anira ubwino wa madzi kwakhala ntchito yosakhazikika pa ngongole zaukadaulo. Akatswiri m'magawo kuyambira ulimi wolondola mpaka kukonza mankhwala akhala akuvutika kwa nthawi yayitali ndi ntchito yokonza zinthu yogwiritsa ntchito masensa ambiri, akuluakulu kuti agwire mbiri ya chitsanzo chimodzi. Kudalira ma probes osiyana a pH, conductivity, ndi mchere sikungowonjezera malo enieni; kumachulukitsa mfundo zolephera ndikupangitsa kuti kulumikizana kwa deta kukhale kovuta. Pamene tikupita ku tsogolo lodziwika ndi "nzeru zamadzimadzi" zenizeni, makampaniwa amafunikira njira yolunjika yopezera zizindikiro. RD-PETSTS-01 imachotsa kukhumudwa kumeneku, m'malo mwa zingwe zomangika ndi yankho limodzi, logwira ntchito bwino lomwe lapangidwira zovuta zamakampani anzeru.

Mphamvu ya Asanu: Kuphatikiza Kwambiri mu Kafukufuku Mmodzi

RD-PETSTS-01 imagwirizanitsa magawo asanu ofunikira a telemetry—pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Salinity, ndi Temperature—mu chipangizo chimodzi chokonzekera kumiza. Kuphatikiza kumeneku kumatsimikizira kuti mfundo zonse za deta zimatengedwa kuchokera ku voliyumu yomweyo ya madzi nthawi imodzi, kupereka chithunzi cholondola cha mphamvu ya yankho kuposa ma probe enaake. Sensor imapereka envelopu yogwira ntchito yolimba: pH kuyambira 0–14, EC mpaka 10,000us/cm, TDS mpaka 5,000ppm, Salinity pa 8ppt, ndi kutentha kwa 0–60℃. Mwa kuchepetsa pamwamba pa hardware ndikupangitsa kuti mawaya akhale osavuta kulumikizana ndi waya umodzi wa waya zinayi, ogwiritsa ntchito amatha:

"Kukwaniritsadi mtengo wotsika, mtengo wotsika komanso magwiridwe antchito apamwamba."

Uinjiniya wa "Kusokoneza Kovuta"

Malo ogwirira ntchito monga malo opangira ma electroplating ndi malo oyeretsera zinyalala amadziwika ndi phokoso lamagetsi lomwe lingachepetse ma signal otsika. Pofuna kuonetsetsa kuti deta ili yokhazikika, RD-PETSTS-01 imagwiritsa ntchito kusefa kwa axial capacitor yamkati ndi resistor ya 100M kuti iwonjezere kwambiri kupondereza kwa input. Iyi ndi njira yofunika kwambiri yopangira mainjiniya kuti isunge umphumphu wa ma signal ndikuletsa kuchepa kwa ma signal pamagetsi atali a mafakitale omwe amagwiritsidwa ntchito kwambiri pa zomangamanga zazikulu. Ndi "ma isolation anayi" ndi IP68 yosalowa madzi, sensayi idapangidwa kuti ipirire kusokonezedwa kwa malo pomwe ikupereka ma input olondola a RS485 ku dongosolo lanu lopezera deta.

Kukula Kofunika: Ubwino wa 42mm

Zoletsa zakuthupi nthawi zambiri zimakhala cholepheretsa chachikulu pakuwunika bwino kwambiri pa zomangamanga zomwe zilipo. RD-PETSTS-01 imathetsa vutoli ndi kutalika kochepa kwa 202mm ndi m'mimba mwake wa thupi la 42mm komwe kumachepa kufika pa nsonga ya 34mm. Mbiri yocheperako iyi idapangidwa makamaka kuti igwiritsidwe ntchito mu "mapaipi ang'onoang'ono" ndi malo otseguka omwe masensa wamba amafakitale sangagwirizane. Popeza "ndi yaying'ono, yolumikizidwa bwino, [ndi] yosavuta kunyamula," imagwira ntchito ziwiri: cholumikizira chokhazikika m'mapaipi olimba komanso chida chonyamulika choyesera mwachangu m'minda m'malo obiriwira alimi kapena m'njira zotulutsira madzi m'mizinda.

Kulumikizana Kopanda Msoko Kuchokera ku Field kupita ku Cloud

Kulumikizana ndi komwe kumasintha chida cha hardware kukhala node yeniyeni ya IoT. Pogwira ntchito pamagetsi a 12 ~ 24V DC, sensa imalumikizana kudzera mu mawonekedwe a RS485 omwe amagwiritsidwa ntchito mumakampani pogwiritsa ntchito protocol ya Modbus-RTU (9600 baud rate). Kwa akatswiri omwe ali m'munda, chipangizochi chimathandizira adilesi yowulutsa ya 0XFE, njira yofunika kwambiri yopezera adilesi yoyambirira ngati yaiwalika kapena yasinthidwa molakwika. Kuphatikizana kuli kosalala; sensa ikhoza kukonzedwa kudzera pa cholumikizira cha USB-to-RS485 kuti ikhazikitsidwe pa PC ndipo imagwirizana ndi osonkhanitsa opanda zingwe omwe amathandizira WIFI, GPRS, 4G, LoRa, kapena LoRaWAN. Izi zimapangitsa kuti pakhale "Data Acquisition System" yonse yomwe imatumiza telemetry yeniyeni ku mapulogalamu ofanana ndi a seva yamtambo kuti iwonetse kutali.

Kulondola Kupyolera mu Kuwerengera kwa Ma Point Ambiri

Kusunga kulondola kwa mafakitale—± 0.1PH ya acidity ndi ± 1% FS ya mchere—kumafuna njira yolimba yowerengera. RD-PETSTS-01 imathandizira kuwerengera kwachiwiri komwe kumayang'aniridwa ndi ogwiritsa ntchito, zomwe zimathandiza kukonza bwino kudzera mu ma registers a Modbus. Ogwiritsa ntchito amatha kuchita kuwerengera pH ya mfundo zitatu pogwiritsa ntchito mayankho okhazikika (4.01, 6.86, ndi 9.18) ndikusintha malo otsetsereka a EC pogwiritsa ntchito yankho la 1413us/cm lomwe ndi lokhazikika m'makampani. Mlingo uwu wa granular control ndi wofunikira kuti sensa ikhale yolondola kutentha kwa ±0.5℃ komanso kukhazikika kwa muyeso wonse pa moyo wake wonse, kuonetsetsa kuti ikukwaniritsa kulekerera kolimba kwa magawo azamankhwala ndi kuteteza chilengedwe.

Kutsiliza: Kupita ku Tsogolo la Madzi Lanzeru Kwambiri komanso Losavuta

RD-PETSTS-01 ikuyimira kusintha kuchoka pa "kufalikira kwa masensa" kupita ku zomangamanga zolumikizidwa bwino komanso zolimba. Mwa kuchepetsa zopinga zakuthupi ndi zachuma pakuwunika madzi okhala ndi magawo ambiri, probe iyi ya 5-in-1 imalola mafakitale kusintha kuchoka pa kusanthula kosinthika kupita ku kasamalidwe kogwiritsa ntchito deta. Pamene mukuwunika gulu lanu lowunikira lomwe lilipo, ganizirani za kuchuluka kwa zinthu zomwe zilipo komanso kusanthula kwa ma probe anu omwe alipo. Kodi mungatsegule bwanji magwiridwe antchito obisika mwa kukweza kupita ku kapangidwe ka "nzeru zamadzimadzi" kosavuta komanso kosavuta?

Matagi:Sensa yamadzi | Sensa yamadzi ya PH | Sensa yamadzi yosungunuka ndi mpweya | Sensa yamadzi ya ammonium ion | Sensa yamadzi ya nitrate ion

Kuti mudziwe zambiri zokhudza sensa ya khalidwe la madzi,
