incazelo yomkhiqizo
1.1Uhlolojikelele
Lesi sivalo socezu olulodwa singasetshenziswa kabanzi ekutholeni indawo ezungezile, ukuhlanganisa ukuqoqwa komsindo, i-PM2.5 ne-PM10, izinga lokushisa kanye nomswakama, ukucindezela komkhathi, nokukhanya.Ifakwe ebhokisini le-louver, okokusebenza kusebenzisa isimiso sokuxhumana esijwayelekile se-MODBUS-RTU, ukuphuma kwesignali ye-RS485, futhi ibanga lokuxhumana eliphakeme lingafinyelela kumamitha angu-2000 (akaliwe).Lesi sidlulisi sisetshenziswa kakhulu ezikhathini ezihlukahlukene ezidinga ukukala izinga lokushisa lendawo kanye nomswakama, umsindo, izinga lomoya, ukucindezela komkhathi nokukhanya, njll. Siphephile futhi sithembekile, yinhle ngokubukeka, kulula ukuyifaka, futhi ihlala isikhathi eside.
1.2Izici
Lo mkhiqizo mncane ngosayizi, ulula ngesisindo, wenziwe ngezinto ezilwa ne-ultraviolet zekhwalithi ephezulu, impilo ende yesevisi, i-high-sensitivity probe, isignali ezinzile, ukunemba okuphezulu.Izingxenye ezibalulekile zamukela izingxenye ezingenisiwe, ezinzile futhi ezinokwethenjelwa, futhi ezinezici zebanga elibanzi lokulinganisa, ukuhleleka okuhle, ukusebenza kahle okungangeni manzi, ukusetshenziswa okulula, ukufakwa kalula, kanye nebanga elide lokudlulisela.
◾ Iqoqo lomsindo, ukulinganisa okunembile, ububanzi buphezulu njengo-30dB~120dB.
◾ PM2.5 kanye ne-PM10 ziqoqwa ngesikhathi esifanayo, ububanzi: 0-1000ug/m3, ukulungiswa 1ug/m3, ukuqoqwa kwedatha okukabili-imvamisa eyingqayizivele kanye nobuchwepheshe bokulinganisa okuzenzakalelayo, ukungaguquguquki kungafinyelela ku-±10%.
◾ Linganisa izinga lokushisa kwemvelo kanye nomswakama, iyunithi yokulinganisa ithunyelwa ivela eSwitzerland, isilinganiso sinembile, futhi ububanzi bungu-40~120 degrees.
◾ Ibanga elibanzi 0-120Kpa ingcindezi yomoya, esebenza ezindaweni ezihlukahlukene zokuphakama.
◾ Imojula yeqoqo lokukhanya isebenzisa i-photosensitive probe ephezulu, futhi ububanzi bokukhanya bungu-0~200,000 Lux.
◾ Sebenzisa isekethe engu-485 ezinikele, ukuxhumana okuzinzile, ukunikezwa kwamandla kagesi okubanzi okungu-10~30V.

Imiyalo yokufaka
2.1 Uhlu lokuhlola ngaphambi kokufakwa
Uhlu Lwezisetshenziswa:
■ 1 umthumeli
■I-USB ukuya ku-485 (Ongakukhetha)
■ Ikhadi lewaranti, isitifiketi sokuvumelana, ikhadi lesevisi yangemuva kokuthengisa, njll.
2.2Incazelo Yesixhumanisi
Ububanzi bokufakwa kwamandla kagesi obanzi 10~30V.Lapho ufaka izintambo ulayini wesignali we-485, naka imigqa emibili A no-B ukuze ingahlehliswa, futhi amakheli emishini eminingi ocingweni oluphelele akumele angqubuzane.
|

2.3485 imiyalelo yezintambo zenkambu
Uma amadivaysi amaningi angu-485 exhunywe ocingweni oluphelele olufanayo, kunezidingo ezithile zokuhlanganisa izintambo zasensimini.Ukuze uthole imininingwane, sicela ubheke "485 Device Field Wiring Manual" kuphakheji yolwazi.
2.4 Isibonelo sokufaka
Ukufakwa nokusetshenziswa kwesofthiwe yokumisa
3.1Ukukhetha isoftware
Vula iphakheji yedatha, khetha "Isofthiwe yokulungisa iphutha" --- "isofthiwe yokumisa ipharamitha engu-485", thola "ithuluzi lokumisa ipharamitha engu-485"
3.2Izilungiselelo zepharamitha
①、Khetha imbobo ye-COM efanele (hlola imbobo ye-COM kokuthi "Ikhompyutha Yami—Izakhiwo—Isiphathi Sedivayisi—Imbobo").Umfanekiso olandelayo ubala amagama omshayeli weziguquli eziningana ezihlukene ze-485.
②, Xhuma idivayisi eyodwa kuphela ngokuhlukile bese uyivula, chofoza izinga lokuhlola le-baud yesofthiwe, isofthiwe izohlola izinga le-baud nekheli ledivayisi yamanje, izinga lokungathembeki elizenzakalelayo ngu-4800bit/s, futhi ikheli elizenzakalelayo ngu-0x01 .
③、Lungisa ikheli nezinga le-baud ngokwezidingo zokusetshenziswa, futhi ngesikhathi esifanayo ubuze isimo samanje sokusebenza kwedivayisi.
④, Uma ukuhlolwa kungaphumeleli, sicela uhlole kabusha izintambo zemishini kanye nokufakwa komshayeli okungu-485.
485 ithuluzi lokumisa ipharamitha
Iphrothokholi Yezokuxhumana
4.1Imingcele yokuxhumana eyisisekelo
| Ikhodi | 8-bit kanambambili |
| Ibhithi yedatha | 8-bit |
| I-Parity bit | Lutho |
| Yima kancane | 1-bhithi |
| Iphutha ekuhloleni | I-CRC (Ikhodi ye-cyclic engasebenzi) |
| Isilinganiso se-Baud | Ingasethelwa ku-2400bit/s, 4800bit/s, 9600 bit/s, okuzenzakalelayo kwasembonini kungu-4800bit/s |
4.2Incazelo yefomethi yozimele wedatha
Yamukela iphrothokholi yokuxhumana ye-Modbus-RTU, ifomethi imi kanje:
Isakhiwo sokuqala ≥4 amabhayithi esikhathi
Ikhodi yekheli = ibhayithi elingu-1
Ikhodi yomsebenzi = ibhayithi elingu-1
Indawo yedatha = amabhayithi angu-N
Ukuhlola iphutha = ikhodi ye-CRC engu-16-bit
Isikhathi sokuqeda isakhiwo ≥ 4 amabhayithi
Ikhodi yekheli: ikheli lokuqala le-transmitter, eliyingqayizivele kunethiwekhi yokuxhumana (okuzenzakalelayo kwefekthri 0x01).
Ikhodi yomsebenzi: umyalo wokusebenza komyalo okhishwe umsingathi, lesi sithumeli sisebenzisa kuphela ikhodi yokusebenza engu-0x03 (funda idatha yerejista).
Indawo yedatha: Indawo yedatha yidatha ethile yokuxhumana, naka i-byte ephezulu yedatha ye-16bits kuqala!
Ikhodi ye-CRC: ikhodi yokuhlola yamabhayithi amabili.
Isakhiwo sohlaka lombuzo wokusingatha:
| Ikhodi yekheli | Ikhodi yomsebenzi | Bhalisa ikheli lokuqala | Ubude bokubhalisa | Hlola ikhodi ephansi kancane | Ikhodi yesheke ephezulu kakhulu |
| 1 ibhayithi | 1 ibhayithi | 2 amabhayithi | 2 amabhayithi | 1 ibhayithi | 1 ibhayithi |
Isakhiwo sefreyimu yempendulo yesigqila:
| Ikhodi yekheli | Ikhodi yomsebenzi | Inombolo yamabhayithi avumelekile | Indawo yedatha | Indawo yesibili yedatha | Indawo yedatha ye-Nth | Hlola ikhodi |
| 1 ibhayithi | 1 ibhayithi | 1 ibhayithi | 2 amabhayithi | 2 amabhayithi | 2 amabhayithi | 2 amabhayithi |
4.3Incazelo yekheli lerejista yokuxhumana
Okuqukethwe kwirejista kukhonjiswe kuthebula elilandelayo (ukusekelwa kwekhodi yokusebenza engu-03/04):
| Bhalisa ikheli | I-PLC noma ikheli lokumisa | Okuqukethwe | Ukusebenza |
| 500 | 40501 | Inani lomswakamo (izikhathi eziyi-10 kunenani langempela) | Funda kuphela |
| 501 | 40502 | Inani lezinga lokushisa (izikhathi eziyi-10 kunenani langempela) | Funda kuphela |
| 502 | 40503 | Inani lomsindo (izikhathi eziyi-10 kunenani langempela) | Funda kuphela |
| 503 | 40504 | PM2.5 (inani langempela) | Funda kuphela |
| 504 | 40505 | PM10 (inani langempela) | Funda kuphela |
| 505 | 40506 | Inani lokucindezela komkhathi (iyunithi Kpa, inani langempela izikhathi eziyi-10) | Funda kuphela |
| 506 | 40507 | Inani eliphakeme le-16-bit yenani le-Lux elingu-20W (inani langempela) | Funda kuphela |
| 507 | 40508 | Inani eliphansi le-16-bit yenani le-Lux elingu-20W (inani langempela) | Funda kuphela |
4.4Isibonelo sephrothokholi yezokuxhumana kanye nencazelo
4.4.1 Buza ngezinga lokushisa lemishini kanye nomswakama
Isibonelo, buza mayelana nezinga lokushisa kanye nevelu yomswakama: ikheli ledivayisi ngu-03
| Ikhodi yekheli | Ikhodi yomsebenzi | Ikheli lokuqala | Ubude bedatha | Hlola ikhodi ephansi kancane | Ikhodi yesheke ephezulu kakhulu |
| 0x03 | 0x03 | 0x01 0xF4 | 0x00 0x02 | 0x85 | 0xE7 |
Uhlaka lokuphendula (isibonelo, izinga lokushisa ngu--10.1℃ kanye nomswakama ngu-65.8%RH)
| Ikhodi yekheli | Ikhodi yomsebenzi | Inombolo yamabhayithi avumelekile | Inani lomswakamo | Inani lokushisa | Hlola ikhodi ephansi kancane | Ikhodi yesheke ephezulu kakhulu |
| 0x03 | 0x03 | 0x04 | 0x02 0x92 | 0xFF 0x9B | 0x79 | 0xFD |
Izinga lokushisa: layisha ngendlela yekhodi ehambisanayo lapho izinga lokushisa lingaphansi kuka-0℃
0xFF9B (Hexadecimal)= -101 => Izinga lokushisa = -10.1℃
Ukuswakama:
0x0292(Hexadecimal)=658=> Umswakamo = 65.8%RH
Izinkinga ezivamile nezisombululo
Idivayisi ayikwazi ukuxhuma ku-PLC noma ikhompuyutha
Isizathu esingaba khona:
1) Ikhompyutha inamachweba amaningi e-COM futhi imbobo ekhethiwe ayilungile.
2) Ikheli ledivayisi alilungile, noma kukhona amadivayisi anamakheli ayimpinda (okuzenzakalelayo kwasembonini konke 1)
3) Izinga le-baud, indlela yokuhlola, i-data bit, ne-stop bit akulungile.
4) Isikhathi sokuvota somsingathi kanye nesikhathi sokuphendula sokulinda sifushane kakhulu, futhi zombili zidinga ukusethwa ngaphezu kuka-200ms.
5) Intambo ephelele engu-485 inqanyuliwe, noma izintambo zika-A no-B zixhunywe ngokuhlehla.
6) Uma inombolo yesisetshenziswa sikhulu kakhulu noma izintambo zinde kakhulu, ukunikezwa kwamandla kufanele kube eduze, engeza i-booster engu-485, bese wengeza ukumelana netheminali engu-120Ω ngesikhathi esifanayo.
7) I-USB kuya kumshayeli we-485 ayifakiwe noma yonakaliswa.
8) Ukulimala kwemishini.
