Intshayelelo: Ubunzima Bobukrelekrele Bolwelo

Kwiziseko zophuhliso lwemizi-mveliso zanamhlanje, ukulawula umgangatho wamanzi bekusoloko kuyinto engaqhelekanga kwityala lobuchwephesha. Iingcali kumacandelo aqala kwezolimo oluchanekileyo ukuya ekucutshungulweni kweekhemikhali bezisoloko zijongene nomthwalo wokuhambisa ii-sensors ezininzi ezinkulu ukuze zibambe iprofayili yesampulu enye. Ukuthembela kwiiprobes ezahlukeneyo ze-pH, ukuqhuba, kunye netyuwa akunyusi nje kuphela umkhondo womzimba; kwandisa amanqaku okusilela kwaye kwenza kube nzima ukuvumelanisa idatha. Njengoko sisiya kwikamva elichazwe "bukrelekrele bolwelo" bexesha langempela, eli shishini lifuna indlela elungelelanisiweyo yokufumana isignali. I-RD-PETSTS-01 iyayisusa le ngxaki, ithatha indawo ye-tangle yeentambo ngesisombululo esinye, esisebenza kakuhle esenzelwe ubunzima beshishini elikrelekrele.

Amandla Ezintlanu: Ukuhlanganiswa Okukhulu Kwiprobe Eyodwa

I-RD-PETSTS-01 idibanisa iiparameter ezintlanu ezibalulekileyo ze-telemetry—i-pH, i-Electrical Conductivity (EC), ii-Total Dissolved Solids (TDS), i-Salinity, kunye ne-Temperature—zibe sisixhobo esinye esilungele ukuntywiliselwa. Olu dibaniselwano luqinisekisa ukuba zonke iingongoma zedatha zibanjwa ukusuka kumthamo wamanzi ofanayo ngaxeshanye, zibonelela ngesithombe esichanekileyo se-dynamics yesisombululo kunee-probes ezizimeleyo ezihleliweyo. I-sensor inikezela nge-envelope yokusebenza eqinileyo: i-pH ukusuka kwi-0–14, i-EC ukuya kwi-10,000us/cm, i-TDS ukuya kwi-5,000ppm, i-Salinity kwi-8ppt, kunye nobubanzi bobushushu obuyi-0–60℃. Ngokunciphisa i-hardware overhead kunye nokwenza lula i-wiring ukuya kuqhagamshelo olunye lweengcingo ezine, abaqhubi banokwenza oku kulandelayo:

"Ngokwenene fezekisa ixabiso eliphantsi, ixabiso eliphantsi kunye nokusebenza okuphezulu."

Ubunjineli "bokuPhazamiseka okuntsonkothileyo"

Iindawo zoshishino ezifana nezakhiwo ze-electroplating kunye nezityalo zonyango lwelindle ziyaziwa ngengxolo yombane enokonakalisa imiqondiso ye-voltage ephantsi. Ukuqinisekisa uzinzo lwedatha, i-RD-PETSTS-01 isebenzisa isihluzo sangaphakathi se-axial capacitor kunye ne-resistor ye-100M ukwandisa kakhulu i-input impedance. Olu lukhetho olubalulekileyo lobunjineli lokugcina ukuthembeka kwesignali kunye nokuthintela ukuncitshiswa phezu kwentambo ende yeshishini eqhelekileyo kwiziseko ezinkulu. Nge-"four isolations" kunye novavanyo lwe-IP68 olungangeni manzi, i-sensor yenzelwe ukumelana nokuphazamiseka kwendawo ngelixa inika igalelo elichanekileyo le-RS485 kwinkqubo yakho yokufumana idatha.

Izinto Ezibalulekileyo: Inzuzo ye-42mm

Imiqobo ebonakalayo idla ngokuba ngumqobo ophambili ekubekweni kweliso elithembekileyo kwiziseko ezikhoyo. I-RD-PETSTS-01 ijongana nale meko ngobude obuncinci obuyi-202mm kunye nobubanzi bomzimba obuyi-42mm obunciphayo ukuya kwincam ye-34mm. Le phrofayili inciphileyo yenzelwe ngokukodwa ukusasazwa "kwiipayipi ezincinci" kunye neembobo ezithintelweyo apho izinzwa zoshishino eziqhelekileyo zingenakungena khona. Ekubeni "zincinci ngobukhulu, zidibene kakhulu, [kwaye] kulula ukuzithwala," isebenza iindima ezimbini: isixhobo esihlala sihleli kwimibhobho eqinileyo kunye nesixhobo esiphathwayo sokuvavanya ngokukhawuleza intsimi kwiindawo zokugcina izityalo zezolimo okanye kwiinkqubo zokuhambisa amanzi ezidolophini.

Unxibelelwano olungenamthungo ukusuka kwiCandelo ukuya kwiLifu

Uqhagamshelo yinto eguqula isixhobo sehardware sibe yi-node yokwenyani ye-IoT. Isebenza kumbane we-12 ~ 24V DC, i-sensor inxibelelana nge-interface ye-RS485 esemgangathweni zoshishino isebenzisa i-protocol ye-Modbus-RTU (izinga le-baud le-9600). Kwabo bachwephesha abakwicandelo, isixhobo sixhasa idilesi yokusasazwa ye-0XFE, indawo ekhuselekileyo yokubuza idilesi yokuqala ukuba ilibele okanye ayilungiswanga kakuhle. Ukuhlanganiswa akunamthungo; i-sensor ingacwangciswa nge-connector ye-USB-to-RS485 yokuseta kwinqanaba le-PC kwaye idityaniswe nabaqokeleli abangenazingcingo abaxhasa i-WIFI, i-GPRS, i-4G, i-LoRa, okanye i-LoRaWAN. Oku kwenza kube lula "iNkqubo yokuFumana iDatha" epheleleyo esasaza i-telemetry yexesha langempela kwisoftware yeseva yelifu ehambelanayo yokujonga kude.

Ukuchaneka Ngokusebenzisa Ukulinganisa Amanqaku Amaninzi

Ukugcina ukuchaneka kwemigangatho yemizi-mveliso—±0.1PH ye-asidi kunye ne-±1% FS yetyuwa—kufuna iprotokholi yokulinganisa eqinileyo. I-RD-PETSTS-01 ixhasa ukulinganiswa kwesibini okuqhutywa ngumsebenzisi, okuvumela ukulungiswa kakuhle ngeerejista zeModbus. Abaqhubi banokwenza ukulinganiswa kwe-pH yamanqaku amathathu besebenzisa izisombululo ezisemgangathweni (4.01, 6.86, kunye ne-9.18) kwaye balungise i-EC slope besebenzisa isisombululo esisemgangathweni we-1413us/cm. Eli nqanaba lolawulo lwe-granular libalulekile ekugcineni ukuchaneka kobushushu be-±0.5℃ yesivamvo kunye nokuzinza kokulinganisa ngokubanzi kulo lonke ixesha layo lobomi, ukuqinisekisa ukuba iyahlangabezana nokunyamezela okungqongqo kwamacandelo okukhusela amayeza kunye nokusingqongileyo.

Isiphelo: Ukuya kwikamva lamanzi elikrelekrele nelilula

I-RD-PETSTS-01 imele utshintsho olusuka "kwi-sensor sprawl" ukuya kwiziseko ezidityanisiweyo nezizinzileyo. Ngokunciphisa imiqobo ebonakalayo neyezemali ekubekweni kweliso kwamanzi okuneeparameter ezininzi, le probe ye-5-in-1 ivumela amashishini ukuba atshintshele kwisampulu esabelayo ukuya kulawulo olusebenzayo noluqhutywa yidatha. Njengoko uvavanya i-stack yakho yangoku yokubeka esweni, cinga ngeendleko zokulungiselela kunye nohlalutyo lwee-probe zakho ezikhoyo. Ingakanani impumelelo efihliweyo onokuyivula ngokuphucula ukuya kwisakhiwo "sobukrelekrele bolwelo" esilula ngakumbi?
