Sheet 2 Tsanangudzo yeAnalog-to-Digital Conversion Module
Iko hakuna chiziviso chekutanga kana chero tsanangudzo yechigadzirwa ichichinja.
Chitsauko 2 Chigadzirwa Overview
2.1 Ruzivo rwechigadzirwa
pH inotsanangura Kugona kweHydrogen yemuviri wemvura uye zvimiro zvayo.Kana pH iri pasi pe7.0, zvinoreva kuti mvura ine acidic;Kana pH yakaenzana ne7.0, zvinoreva kuti mvura haina kwayakarerekera, uye kana pH iri kupfuura 7.0, zvinoreva kuti mvura ine alkaline.
Iyo pH sensor inoshandisa composite electrode inosanganisa girazi rinoratidza electrode uye referensi electrode kuyera pH yemvura.Iyo data yakagadzikana, kuita kwakavimbika, uye kuisa kuri nyore.
Inoshandiswa zvakanyanya muminda yakadai semiti yetsvina, mabasa emvura, zviteshi zvemvura, mvura yepamusoro, uye maindasitiri;Mufananidzo 1 inopa iyo dimensional dhizaini inoratidza saizi ye sensor.
Mufananidzo 1 Saizi ye sensor
2.2 Ruzivo rwekuchengetedza
Ndokumbira uverenge bhuku rino zvizere usati wavhura pasuru, kuisa kana kushandisa.Zvikasadaro zvinogona kukonzera kukuvara kwemunhu kune anoshanda, kana kukonzera kukuvadzwa kwemidziyo.
Yambiro mavara
Ndokumbira uverenge mavara ese nezviratidzo zviri pachiridzwa, uye tevedzera mirairo ine chekuchengetedza, zvikasadaro zvinogona kukonzera kukuvara kwemunhu kana kukuvara kwemidziyo.
Kana chiratidzo ichi chikaonekwa muchiridzwa, ndapota tarisa kumashandiro kana ruzivo rwekuchengetedza mugwaro rereferensi.
Nepo chiratidzo ichi chinoratidza kuvhunduka kwemagetsi kana njodzi yekufa kubva kumagetsi.
Ndapota verenga bhuku rino zvizere.Nyatsoteerera kune mamwe manotsi kana yambiro, nezvimwewo Kuve nechokwadi chekuti matanho ekudzivirira anopihwa nemidziyo haana kuparadzwa.

3.2 Sensor Kubatanidza
(1) Chekutanga, Batanidza sensor yekubatanidza kune analog-to-digital inoshandura module sezvakaratidzwa pazasi.
(2) Uye zvino zvakateerana batanidza musimboti wetambo kuseri kwemodule zvinoenderana netsanangudzo yepakati.Kubatana chaiko pakati pe sensor uye tsananguro yepakati:
| Siriyero nhamba | 1 | 2 | 3 | 4 |
| Sensor Wire | Bhurawuni | Nhema | Bhuruu | Yero |
| Signal | +12VDC | AGND | RS485 A | RS485 B |
(3)PH analog-to-digital converter module joint ine kapfupi kupisa chubhu inogona kushandiswa pagrounding.Paunenge uchishandisa kupisa kunopisa chubhu inofanira kuchekwa yakavhurika, ichiratidza mutsara mutsvuku pasi.
Chitsauko 4 Interface uye Operation
4.1 Mushandisi Interface
① Iyo sensor inoshandisa RS485 ku USB yekubatanidza pakombuta, uye wozoisa iyo CD-ROM software Modbus Poll kune yepamusoro komputa, tinya kaviri uye ita iyo Mbpoll.exe kutevedzera zvinokurudzirwa kuisirwa, pakupedzisira, unogona kupinda mushandisi interface.
② Kana iri kekutanga, unofanira kutanga wanyoresa.Dzvanya "Connection" pane menyu bar uye sarudza mutsara wekutanga mune yekudonha-pasi menyu.Connection Setup icharatidza dialog box rekunyoresa.Semufananidzo unoratidzwa pasi apa.Kopa kodhi yekunyoresa yakabatanidzwa kune Registration Key uye tinya "OK" kuti upedze kunyoresa.
4.2 Parameter Setting
1. Dzvanya Setup pane menyu bar, sarudza Read / Nyora Tsanangudzo, uye wobva wadzvanya OK mushure mekutevera Chifananidzo chiri pasi apa kuti uise zvaunofarira.
Cherechedza:Iyo yekutanga default kero yemuranda (ID yemuranda) ndeye 2, uye kana kero yemuranda yachinjwa, kero yemuranda inotaurirwa nekero nyowani uye kero yemuranda inotevera ndiyo zvakare yakashandurwa kero.
2. Dzvanya Connection pane menyu bar, sarudza mutsara wekutanga mune yekudonha-pasi menyu Connection setup, ita seFigure inoratidzwa pazasi, uye baya OK.
Cherechedza:Port inoiswa zvinoenderana nenhamba yechiteshi chekubatanidza.
Cherechedza:Kana iyo sensor yakabatana sezvakatsanangurwa, uye iyo software Dhizaina chimiro inoratidzika Hapana Kubatana, zvinoreva kuti haina kubatana.Bvisa uye tsiva iyo USB port kana tarisa iyo USB kune RS485 inoshandura, dzokorora oparesheni iri pamusoro kusvika iyo sensor yekubatanidza yabudirira.
Chitsauko 5 Kugadziriswa kweSensor
5.1 Gadziriro yekuenzanisa
Pamberi pekuyedzwa uye kuenzanisa, kumwe kugadzirira kunoda kuitirwa sensor, izvo zvinotevera:
1) Usati waedzwa, bvisa bvunzo soak bhodhoro kana chivharo cherabha chinoshandiswa kuchengetedza electrode kubva kune soak mhinduro, nyudza iyo yekuyeresa terminal ye electrode mumvura yakasvibiswa, kurunga uye uiite yakachena;wobva wadhonza electrode kubva mumushonga, uye chenesa mvura yakasvibiswa nesefa bepa.
2) Tarisa mukati megirobhu rinonzwa kuti uone kana rizere nemvura, kana mabubbles awanikwa, yekuyeresa terminal ye electrode inofanira kuzununguswa zvinyoro nyoro ichidzika pasi (sekuzunza thermometer yemuviri) kubvisa mabhubhu mukati megirobhu rinonzwa, zvikasadaro zvichakanganisa kururama kwebvunzo.
5.2 PH Calibration
Iyo pH sensor inoda kuverengerwa isati yashandiswa.Self-calibration inogona kuitwa sezvinotevera maitiro.pH calibration inoda 6.86 pH uye 4.01 pH yakajairwa buffer mhinduro, iwo matanho chaiwo ndeaya anotevera:
1. Batanidza sensor kuPC kuti uone kuti kuwirirana kwacho kwakarurama uye wozoiisa mumushonga webuffer ne pH ye 6.86 uye simbisa mhinduro pachiyero chakakodzera.
2. Mushure mekunge data yagadzikana, tinya kaviri dhata yedata kudivi rekurudyi re6864 uye isa iyo buffer solution kukosha ye6864 (inomiririra mhinduro ine pH ye6.864) mu calibration neutral solution register, sezvinoratidzwa mumufananidzo unotevera. , wobva wadzvanya Send.
3. Bvisa probe, sukurudza probe nemvura ine deionized, uye chenesa mvura yasara nesefa bepa;wobva waiisa mubuffer solution ine pH ye4.01 uye kurunga nemushonga wacho pamwero wakakodzera.Mirira kusvika data ragadzikana, tinya kaviri bhokisi redata riri kurudyi rwe4001 wozadza 4001 buffer solution (inomiririra pH ye4.001) mucalibration acid solution register, sezvaratidzwa mumufananidzo unotevera, wobva wadzvanya. Send.
4.Mushure meiyo acid point solution calibration yapera, sensor inoshambidzwa nemvura yakasvibiswa, uye yakaomeswa;ipapo sensor inogona kuyedzwa nemhinduro yekuyedza, rekodha iyo pH kukosha mushure mekunge yadzikamiswa.
Chitsauko 6 Kukurukurirana Protocol
A.Analog-to-digital conversion module ine MODBUS RS485 communication function, inotora RTU senzira yekutaurirana kwayo, ine baud rate inosvika ku19200, tafura yeMODBUS-RTU chaiyo inotevera.

Chitsauko 7 Kuchengeta uye Kuchengeta
Kuti uwane mhedzisiro yekuyera yakanakisa, kuchengetwa kwenguva dzose uye kugadzirisa kunodiwa zvakanyanya.Kutarisira uye kugadzirisa kunonyanya kusanganisira kuchengetedza kwe sensor, kutarisa sensor kuti ione kana yakakuvadzwa kana kwete uye zvichingodaro.Zvichakadaro, chimiro che sensor chinogona kucherechedzwa panguva yekutarisira uye kuongororwa.
7.1 Sensor Kucheneswa
Mushure mekushandisa kwenguva refu, kutsetseka uye kumhanya kwekupindura kwe electrode kunogona kuderera.Iyo yekuyeresa terminal ye electrode inogona kunyudzwa mu 4% HF kwemasekonzi matatu ~ 5 kana diluted HCl mhinduro kwemaminitsi 1 ~ 2.Uye wozoshambidzwa nemvura yakanyungudutswa mu potassium chloride (4M) mhinduro uye yakanyoroveswa kwemaawa makumi maviri nemana kana kupfuura kuti ive itsva.
7.2 Kuchengetedza Sensor
Munguva yepakati pekushandiswa kwe electrode, ndapota edza kuchenesa iyo yekuyera terminal ye electrode nemvura yakasvibiswa.Kana iyo electrode isingashandisi kwenguva yakareba;inofanira kucheneswa uye kuomeswa, uye inofanira kuchengetwa mubhodhoro rakabatanidzwa soak kana chivharo cherabha chine mhinduro yekunyura.
7.3 Kuongorora pane kukuvara kwe sensor
Tarisa kutaridzika kweiyo sensor uye girazi bulbs kuti uone kana yakakuvadzwa kana kwete, kana kukuvara kwawanikwa, zvinodikanwa kutsiva sensor munguva.Mumhinduro yakaedzwa, kana iine girobhu rinonzwa kana junction-blocking zvinhu zvichisiya electrode passivation, chiitiko chacho chinononoka zvakanyanya nguva yekupindura, kuderera kwemateru kana kuverenga kusina kugadzikana.Somugumisiro, inofanira kunge yakavakirwa pamhando yezvinosvibisa izvi, shandisa iyo yakakodzera solvent yekuchenesa, nokudaro ichiita kuti ive itsva.Zvinosvibisa uye maDetergent akakodzera akanyorwa pazasi kuti aonekwe.
