Ukulinganisa kanye Nesilinganiso
YENZA Ukulinganisa Ezinkethweni
Setha kabusha ukulinganisa
a) Setha kabusha ukulinganisa okungu-100%.
Umsebenzisi ubhala 0x0220 = 8
b) Setha kabusha ukulinganiswa okungu-0%.
Umsebenzisi ubhala 0x0220 = 16
c) Setha kabusha ukulinganiswa kwezinga lokushisa.
Umsebenzisi ubhala 0x0220 = 32
1-iphoyinti lokulinganisa
Ukulinganisa kwephuzu elingu-1 kusho ukulinganisa uphenyo endaweni yokugcwala kwe-100%, engatholwa ngenye yalezi zindlela ezilandelayo:
a) Emanzini agcwele umoya (indlela ejwayelekile).
Amanzi agcwele umoya (isbample ka-500 mL) ingatholakala ngokuqhubekayo (1) ngokuhlanza amanzi ngomoya kusetshenziswa ibhamuza lomoya noma uhlobo oluthile lokungenisa umoya cishe imizuzu emi-3 ~ 5, noma (2) ukunyakazisa amanzi ngesishukumisi kazibuthe ngaphansi kuka-800 rpm ihora elingu-1.
Ngemuva kokuthi amanzi agcwele umoya eselungile, cwilisa isivalo senzwa kanye nenzwa yokushisa ye-probe emanzini agcwele umoya, bese ulinganisa uphenyo ngemva kokuthi ukufunda kuzinzile (imvamisa imizuzu engu-1 ~ 3).
Umsebenzisi ubhala 0x0220 = 1 , bese elinda imizuzwana engu-30.
Uma ukufundwa kokugcina kwe-0x0102 kungekho ku-100 ± 0.5%, sicela uhlole ukuthi ingabe ukuzinza kwendawo yokuhlola yamanje noma uzame futhi.
b) Emoyeni ogcwele amanzi (indlela elula).
Okunye, ukulinganisa kwe-1-pt kungenziwa kalula kusetshenziswa umoya ogcwele amanzi, kodwa iphutha elingu-0 ~ 2% lingase lidalwe kuye ngemisebenzi ehlukene. Izinqubo ezinconyiwe zinikezwa kanje:
i) cwilisa isivalo senzwa kanye nenzwa yezinga lokushisa yophenyo emanzini amasha/ampompi amaminithi angu-1 ~ 2.
ii) khipha i-probe bese ucwilisa ngokushesha amanzi omisa phezu kwe-sensor cap ngethishu.
iii) faka isiphetho senzwa ebhodleleni lokulinganisa/lesitoreji elinesipontshi esimanzi ngaphakathi. Gwema ukuthintana okuqondile kwekepisi yenzwa nganoma imaphi amanzi asebhodleleni lokulinganisa/isitoreji phakathi nalesi sinyathelo sokulinganisa. Gcina ibanga eliphakathi kwekepisi lenzwa nesipontshi esimanzi libe ngu-~ 2 cm.
v) linda ukuthi ukufundwa kuzinze (2 ~ 4 amaminithi ) bese ubhala 0x0220 = 2.
Ukulinganisa amaphuzu angu-2 (amaphuzu angu-100% kanye no-0% wokugcwaliswa kwesikhala)
(i) Faka uphenyo emanzini agcwele umoya, bhala 0x0220 = 1 ngemva kokuthi ukufunda kwe-DO kuzinzile.
(ii) Ngemuva kokuthi ukufunda kwe-DO kuba ngu-100%, hambisa i-probe emanzini oksijini ayiziro (sebenzisa i-sodium sulfide engezwe ngokweqile
amanzi sample).
(iii) Bhala 0x0220 = 2, ngemva kokuba ukufunda kwe-DO kuzinzile (~okungenani imizuzu emi-2).
- (iv) Ukugcwaliswa kwesikhala kokufunda komsebenzisi kokuthi 0x0102 ukuze kulinganiswe iphuzu elingu-1, 0x0104 ukuze kulinganiswe amaphuzu angu-2.
I-2-point cal ayidingekile ezinhlelweni eziningi, ngaphandle kwalapho abasebenzisi badinga ukulinganisa okunembe kakhulu ekugxiliseni okuphansi kwe-DO (<0.5 ppm). - Ukuphoqelela "0% ukulinganisa" ngaphandle kokuthi "100% ukulinganisa" akuvunyelwe.
Iphoyinti lokulinganisa izinga lokushisa
i) Umsebenzisi ubhala 0x000A = izinga lokushisa le-ambient x100 (Isibonelo: Uma izinga lokushisa le-ambient = 32.15, umsebenzisi uzobhala 0x000A=3215).
ii) Izinga lokushisa lokufunda ngu-0x000A. Uma ilingana nalokho okufakile, ukulinganisa kuyenziwa. Uma kungenjalo, sicela uzame Isinyathelo 1 futhi.
I-Modbus RTU Protocol
Isakhiwo somyalo:
- Imiyalo akufanele ithunyelwe ngokushesha kuno-50mS kusukela ekuqedeni impendulo yokugcina.
- Uma impendulo elindelekile evela encekwini ingabonakali> 25mS, phonsa iphutha lokuxhumana.
- I-Probe ilandela indinganiso ye-Modbus yemisebenzi 0x03, 0x06, 0x10, 0x17
Isakhiwo se-Serial Transmission:
- Izinhlobo zedatha zi-big-endian ngaphandle kwalapho kuphawulwe ngenye indlela.
- Ukudluliswa ngakunye kwe-RS485 kuzoba nalokhu: isiqalo esisodwa, amabhithi edatha ayi-8, akukho ukulingana okuncane , kanye nezingcezu zokuma ezimbili;
- Izinga le-Baud elizenzakalelayo: 9600 (ezinye ze-probe zingase zibe ne-Baudrate ye-19200);
- Ikheli lesigqila elizenzakalelayo: 1
- Amabhithi edatha ayi-8 adluliswa ngemuva kwebhithi yokuqala ayincanyana ebaluleke kakhulu kuqala.
- I-Bit Sequence
| Qala kancane | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | Yima kancane |
Isikhathi
- Izibuyekezo ze-Firmware kufanele zisebenze phakathi kwamasekhondi angu-5 amandla avuliwe noma asethwe kabusha ngokuthambile Ithiphu ye-Probe LED izoba luhlaza okwesibhakabhaka okuqinile ngalesi sikhathi.
- Umyalo wokuqala awukwazi ukusetshenziswa ngaphambi kwamasekhondi angu-8 kusukela ekuvuleni amandla noma ekusetheni kabusha okuthambile
- Uma ingekho impendulo elindelekile kumyalo okhishiwe wokuphelelwa yisikhathi kwenzeka ngemuva kuka-200ms

Isondlo
Ukunakekelwa kwe-probe kuhlanganisa ukuhlanza ikepisi lenzwa, kanye nesimo esifanele, ukulungiswa, nokugcinwa kwesistimu yokuhlola.
Uma i-probe ingasebenzi, kunconyelwa kakhulu ukuthi ugcine i-probe ne-sensor cap efakiwe kanye nebhodlela lokulinganisa/isitoreji elifakwe ephaketheni lokuqala, lafakwa ku-probe. Ibhakha lamanzi ahlanzekile noma umshini wokuvala omanzi/omswakama unganele uma ibhodlela lokulinganisa/isitoreji lingekho. Isipontshi esingaphakathi kwebhodlela lokulinganisa/isitoreji kufanele sigcinwe simanzi ukuze kube nemiphumela engcono kakhulu.
Gwema isivalo senzwa esithinta i-organic solvent, ukunwaya, nokungqubuzana okuhlukumezayo ukuze uqinise futhi andise impilo yokusebenza yekepisi yenzwa. Ukunakekelwa okukhethekile kufanele kuthathwe ukuhlanza ukumbozwa kwe-cap, ukucwilisa i-probe kanye ne-cap emanzini ahlanzekile, bese uthinta ukomisa ubuso ngethishu. Ungasuli i-coating surface.
Shintsha isivalo senzwa, uma ikepisi lifiphele noma lisusiwe. UNGATHI UNGATHInti iwindi elicacile ethiphu ye-probe ngemva kokukhulula ikepisi elidala. Uma kukhona ukungcola noma izinsalela efasiteleni noma ngaphakathi kwekepisi, zisuse ngokucophelela nge-powder free wipe. Bese usikulufa kabusha ikepisi yenzwa entsha ku-probe.
