Isingeniso: Ubunzima Bokuhlakanipha Okungamanzi

Engqalasizinda yezimboni zanamuhla, ukuphatha ikhwalithi yamanzi kube yinto engavamile ngokwezimali zobuchwepheshe. Ochwepheshe emikhakheni esukela kwezolimo olunembile kuya ekucutshungulweni kwamakhemikhali bebelokhu belwa nomthwalo wezokuthutha wokusebenzisa izinzwa eziningi ezinkulu ukuze babambe iphrofayili yesampula eyodwa. Ukuthembela kuma-probe ahlukene we-pH, i-conductivity, kanye nosawoti akugcini nje ngokwandisa indawo ebonakalayo; kwandisa amaphuzu okwehluleka futhi kuyinkimbinkimbi ukuvumelanisa idatha. Njengoba siqhubekela phambili ekusaseni elichazwa "ubuhlakani boketshezi" besikhathi sangempela, imboni idinga indlela elula yokuthola isignali. I-RD-PETSTS-01 iqeda lokhu kukhungatheka, ithathe indawo yezintambo ezixubile ngesisombululo esisodwa, esisebenza kahle kakhulu esenzelwe ukuqina kwemboni ehlakaniphile.

Amandla Abahlanu: Ukuhlanganiswa Okukhulu Ku-Probe Eyodwa

I-RD-PETSTS-01 ihlanganisa amapharamitha amahlanu abalulekile e-telemetry—i-pH, i-Electrical Conductivity (EC), i-Total Dissolved Solids (TDS), i-Salinity, kanye ne-Temperature—edivayisini eyodwa elungele ukucwiliswa. Lokhu kuhlanganiswa kuqinisekisa ukuthi wonke amaphuzu edatha athathwa kusukela kumthamo wamanzi ofanayo ngesikhathi esisodwa, okunikeza isithombe esinembile kakhulu se-solution dynamics kune-staggered individual probes. Inzwa inikeza i-operation environment eqinile: i-pH kusuka ku-0–14, i-EC kuya ku-10,000us/cm, i-TDS kuya ku-5,000ppm, i-Salinity ku-8ppt, kanye nobubanzi bokushisa obungu-0–60℃. Ngokunciphisa i-hardware overhead kanye nokwenza lula izintambo zibe uxhumano olulodwa lwezintambo ezine, opharetha bangenza okulandelayo:

"Impela finyelela izindleko eziphansi, intengo ephansi kanye nokusebenza okuphezulu."

Ubunjiniyela “Bokuphazamisa Okuyinkimbinkimbi”

Izindawo zezimboni ezifana nezindawo zokufaka i-electroplating kanye nezindawo zokuhlanza indle zidume ngomsindo kagesi ongalimaza izimpawu ze-voltage ephansi. Ukuqinisekisa ukuzinza kwedatha, i-RD-PETSTS-01 isebenzisa ukuhlunga kwe-axial capacitor yangaphakathi kanye ne-resistor engu-100M ukwandisa kakhulu i-input impedance. Lokhu kuyindlela ebalulekile yobunjiniyela yokugcina ubuqotho besignali nokuvimbela ukuncishiswa kwe-attenuation phezu kwezintambo zezimboni ezinde ezivamile engqalasizinda enkulu. Nge-"four isolations" kanye nesilinganiso sokuvimbela amanzi se-IP68, inzwa yakhelwe ngenhloso ukumelana nokuphazamiseka kwendawo ngenkathi iletha okokufaka okuhlukile kwe-RS485 ohlelweni lwakho lokuthola idatha.

Izinto Ezibalulekile Kusayizi: Inzuzo Engu-42mm

Imingcele ebonakalayo ivame ukuba yisithiyo esiyinhloko ekuqapheni okuphezulu kwengqalasizinda ekhona. I-RD-PETSTS-01 ibhekana nalokhu ngobude obuncane obungu-202mm kanye nobubanzi bomzimba obungu-42mm obunciphayo bufinyelele esicongweni esingu-34mm. Le phrofayili enciphile yenzelwe ngqo ukufakwa “kumapayipi amancane” kanye nezimbobo ezinqunyelwe lapho izinzwa zezimboni ezijwayelekile zingenakungena khona. Njengoba “zincane ngosayizi, zihlanganiswe kakhulu, [futhi] kulula ukuzithwala,” isebenza izindima ezimbili: into ehlala njalo ekufakweni kwamapayipi aqinile kanye nethuluzi eliphathekayo lokuhlola okusheshayo ensimini ezindaweni zokugcina izitshalo zezolimo noma izinhlelo zokudonsa amanzi zasemadolobheni.

Ukuxhumana Okungenamthungo kusuka eNkambini kuya efwini

Ukuxhumana yikho okuguqula ithuluzi lehadiwe libe yi-node yangempela ye-IoT. Isebenza kugesi ongu-12 ~ 24V DC, inzwa ixhumana nge-interface ye-RS485 ejwayelekile embonini isebenzisa iphrothokholi ye-Modbus-RTU (isilinganiso se-baud esingu-9600). Kwabochwepheshe abasensimini, idivayisi isekela ikheli lokusakaza le-0XFE, okuyisivikelo esibalulekile sokuxazulula ikheli lokuqala uma likhohliwe noma lingalungiselelwanga kahle. Ukuhlanganiswa kukhululekile; inzwa ingalungiselelwa ngesixhumi se-USB-to-RS485 sokusetha izinga le-PC futhi ihlanganiswe nabaqoqi abangenantambo abasekela i-WIFI, i-GPRS, i-4G, i-LoRa, noma i-LoRaWAN. Lokhu kuvumela "uHlelo Lokuthola Idatha" oluphelele olusakaza i-telemetry yesikhathi sangempela kusofthiwe yeseva yamafu ehambisanayo yokuqapha okude.

Ukunemba Ngokusebenzisa Ukulinganisa Kwamaphuzu Amaningi

Ukugcina ukunemba kwezinga lezimboni—±0.1PH ye-acidity kanye ne-±1% FS ye-salinity—kudinga inqubo eqinile yokulinganisa. I-RD-PETSTS-01 isekela ukulinganiswa kwesibili okuqhutshwa ngumsebenzisi, okuvumela ukulungiswa kahle ngamarejista e-Modbus. Abasebenzi bangenza ukulinganiswa kwe-pH yamaphuzu amathathu besebenzisa izixazululo ezijwayelekile (4.01, 6.86, kanye ne-9.18) futhi balungise ukuthambekela kwe-EC besebenzisa isisombululo se-1413us/cm esijwayelekile embonini. Leli zinga lokulawula okuhlanganisiwe libalulekile ekugcineni ukunemba kokushisa kwe-±0.5℃ kwenzwa kanye nokuqina kokulinganisa okuphelele kulo lonke umjikelezo wayo wokuphila, ukuqinisekisa ukuthi ihlangabezana nokubekezelelana okuqinile kwemikhakha yemithi kanye nokuvikelwa kwemvelo.

Isiphetho: Ukuya Ekusasa Lamanzi Elihlakaniphile Nelilula

I-RD-PETSTS-01 imele ukushintshela "ekusabalaleni kwenzwa" iye engqalasizindani ehlanganisiwe kakhulu neqinile. Ngokunciphisa izithiyo zomzimba nezezezimali ekuqapheni kwamanzi okunamapharamitha amaningi, le probe engu-5-in-1 ivumela izimboni ukuthi zishintshele ekuthatheni isampula esabelayo ziye ekuphathweni okusebenzayo, okuqhutshwa idatha. Njengoba uhlola inqwaba yakho yokuqapha yamanje, cabanga ngezindleko zokuthutha kanye nokuhlaziya zama-probe akho akhona. Kungakanani ukusebenza kahle okufihliwe ongakuvula ngokuthuthukela kusakhiwo "sobuhlakani obuwuketshezi" esilula kakhulu, esilula kakhulu?
