Iphrothokholi Yezokuxhumana
Umkhiqizo usebenzisa ifomethi yephrothokholi ejwayelekile ye-RS485 MODBUS-RTU, yonke imiyalo yokusebenza noma yokuphendula iyidatha ye-hexadecimal. Ikheli ledivayisi elizenzakalelayo li-1 uma idivayisi ithunyelwa, isilinganiso se-baud esizenzakalelayo ngu-9600, 8, n, 1
- Funda Idatha (I-id yomsebenzi 0x03)
Uhlaka lombuzo (i-hexadecimal), ukuthumela isibample: Umbuzo 1# idivayisi 1 idatha, ikhompuyutha engusokhaya ithumela umyalo:01 03 00 00 00 01 84 0A .I-ID yedivayisi I-id yomsebenzi Qala Ikheli Ubude beDatha CRC16 01 03 00 00 00 01 84A Ukuze uthole uhlaka olulungile lombuzo, idivayisi izophendula ngedatha:01 03 02 00 79 79 A6 , ifomethi yokuphendula icutshungulwa kanjena:
I-ID yedivayisi I-id yomsebenzi Ubude beDatha 数据 1 Hlola Ikhodi 01 03 02 00 79 79 A6 Incazelo Yedatha: Idatha esemyalweni iyi-hexadecimal. Thatha idatha 1 njengesiboneloample. 00 79 iguqulelwa enanini ledesimali lika-121. Uma ukukhuliswa kwedatha kuyi-100, inani langempela lingu-121/100=1.21. Abanye njalo njalo.'
- Ithebula Lekheli Ledatha
Ikheli Qala Ikheli Incazelo Uhlobo lwedatha Ibanga lenani 40001 00 00 1#ukubhalisa umsindo Funda kuphela 0 ~ 65535 40101 00 64 ikhodi yemodeli funda/bhala 0 ~ 65535 40102 00 65 amaphuzu aphelele funda/bhala 1 ~ 20 40103 00 66 I-ID yedivayisi funda/bhala 1 ~ 249 40104 00 67 isilinganiso se-baud funda/bhala 0 ~ 6 40105 00 68 imodi funda/bhala 1 ~ 4 40106 00 69 Iphrothokholi funda/bhala 1 ~ 10 - funda futhi ulungise ikheli ledivayisi
- Funda noma ubuze ngekheli ledivayisi
Uma ungalazi ikheli ledivayisi yamanje futhi kukhona idivayisi eyodwa kuphela ebhasini, ungasebenzisa umyalo FA 03 00 64 00 02 90 5F Umbuzo ikheli idivayisi.I-ID yedivayisi I-id yomsebenzi Qala Ikheli Ubude beDatha CRC16 FA 03 00 64 00 02 90 5f I-FA ingu-250 yekheli elijwayelekile. Uma ungalazi ikheli, ungasebenzisa okuthi 250 ukuze uthole ikheli langempela ledivayisi, 00 64 irejista yemodeli yedivayisi.
Ukuze uthole umyalo olungile wombuzo, idivayisi izophendula, isiboneloample idatha yempendulo ithi: 01 03 02 07 12 3A 79, ifomethi yayo eboniswe kuthebula elilandelayo:I-ID yedivayisi I-id yomsebenzi Qala Ikheli Ikhodi Yesibonelo CRC16 01 03 02 55 3C 00 01 3A 79 Impendulo kufanele ibe kudatha, i-byte yokuqala engu-01 ibonisa ukuthi ikheli langempela ledivayisi yamanje, 55 3C iguqulelwe ku-decimal 20182 ibonisa ukuthi imodeli eyinhloko yedivayisi yamanje ingu-21820, amabhayithi amabili okugcina 00 01 Ibonisa ukuthi idivayisi ine- ubungako besimo.
- Shintsha ikheli ledivayisi
Okwesiboneloample, uma ikheli lamanje ledivayisi lingu-1, sifuna ukushintshela ku-02, umyalo uthi:01 06 00 66 00 02 E8 14.I-ID yedivayisi I-id yomsebenzi Qala Ikheli Indawo oya kuyo CRC16 01 06 00 66 00 02 e8 14 Ngemuva kokuthi ushintsho lube yimpumelelo, idivayisi izobuyisela ulwazi: 02 06 00 66 00 02 E8 27 , ifomethi yayo idluliswa njengoba kuboniswe kuthebula elilandelayo:
I-ID yedivayisi I-id yomsebenzi Qala Ikheli Indawo oya kuyo CRC16 01 06 00 66 00 02 e8 27 Impendulo kufanele ibe kudatha, ngemva kokuba ukuguqulwa kuphumelele, i-byte yokuqala ikheli ledivayisi entsha. Ngemuva kokuthi ikheli ledivayisi elijwayelekile lishintshiwe, lizoqala ukusebenza ngokushesha. Ngalesi sikhathi, umsebenzisi udinga ukushintsha umyalo wombuzo wesofthiwe ngesikhathi esifanayo.
- Funda noma ubuze ngekheli ledivayisi
- Funda futhi Ulungise I-Baud Rate
- Funda isilinganiso se-baud
Izinga le-baud yasembonini elimisiwe ledivayisi ngu-9600. Uma udinga ukulishintsha, ungalishintsha ngokwethebula elilandelayo kanye nephrothokholi yokuxhumana ehambisanayo. Okwesiboneloample, funda i-ID yezinga le-baud yedivayisi yamanje, umyalo uthi:01 03 00 67 00 01 35 D5 , ifomethi yayo icutshungulwa ngendlela elandelayo.I-ID yedivayisi I-id yomsebenzi Qala Ikheli Ubude beDatha CRC16 01 03 00 67 00 01 35 d5 Funda isilinganiso se-baud encoding yedivayisi yamanje. Umbhalo wekhodi we-Baud rate: 1 ngu-2400; 2 ngu-4800; 3 ngu-9600; 4 ngo-19200; 5 ngu-38400; 6 ngu-115200.
Ukuze uthole umyalo olungile wombuzo, idivayisi izophendula, isiboneloample idatha yempendulo ithi: 01 03 02 00 03 F8 45, ifomethi yayo eboniswe kuthebula elilandelayo:I-ID yedivayisi I-id yomsebenzi Ubude beDatha Linganisa i-ID CRC16 01 03 02 00 03 f8 45 efakwe ikhodi ngokwezinga le-baud, u-03 ngu-9600, okusho ukuthi idivayisi yamanje inezinga le-baud elingu-9600.
- Shintsha izinga le-baud
Okwesiboneloample, ukushintsha izinga le-baud kusuka ku-9600 kuya ku-38400, okungukuthi ukushintsha ikhodi kusuka ku-3 kuya ku-5, umyalo uthi: 01 06 00 67 00 05 F8 1601 03 00 66 00 01 64 15.I-ID yedivayisi I-id yomsebenzi Qala Ikheli I-Target Baud Rate CRC16 01 03 00 66 00 01 64 15 Shintsha izinga le-baud lisuka ku-9600 liye ku-38400, shintsha ikhodi isuka ku-3 iye ku-5. Izinga le-baud elisha lizoqala ukusebenza ngokushesha, lapho idivayisi izolahlekelwa impendulo yayo futhi izinga le-baud ledivayisi kufanele libuzwe ngokufanele. Kulungisiwe.
- Funda isilinganiso se-baud
- Funda Inani Lokulungisa
- Funda Inani Lokulungisa
Uma kunephutha phakathi kwedatha nezinga lereferensi, singehlisa iphutha lesibonisi ngokulungisa inani lokulungisa. Umehluko wokulungisa ungashintshwa ube uhlanganisa noma ukhiphe u-1000, i-t hat iwukuthi, ububanzi bevelu ngu-0-1000 noma 64535 -65535. Okwesiboneloample, lapho inani lokubonisa lilincane kakhulu, singalilungisa ngokungeza i-100. Umyalo uthi: 01 03 00 6B 00 01 F5 D6 . Emyalweni othi 100 uthi i-hex 0x64 Uma udinga ukunciphisa, ungasetha inani elingafanele, njengokuthi -100, elihambisana nenani le-hexadecimal lika-FF 9C, elibalwa njenge-100-65535=65435, bese liguqulelwa ku-hexadecimal ukuze 0x FF 9C. Inani lokulungisa liqala ku-00 6B. Sithatha ipharamitha yokuqala njenge-example. Inani lokulungisa liyafundwa futhi lilungiswe ngendlela efanayo kumapharamitha amaningi.I-ID yedivayisi I-id yomsebenzi Qala Ikheli Ubude beDatha CRC16 01 03 00 6b 00 01 F5 D6 Ukuze uthole umyalo olungile wombuzo, idivayisi izophendula, isiboneloample idatha yempendulo ithi: 01 03 02 00 64 B9 AF, ifomethi yayo eboniswe kuleli thebula elilandelayo:
I-ID yedivayisi I-id yomsebenzi Ubude beDatha Inani ledatha CRC16 01 03 02 00 64 B9 AF Kudatha yempendulo, i-byte yokuqala engu-01 ibonisa ikheli langempela ledivayisi yamanje, futhi i-00 6B iyirejista yenani lokulungiswa kwenani lokuqala lesifundazwe. Uma idivayisi inamapharamitha amaningi, amanye amapharamitha asebenza ngale ndlela. Ngokufanayo, izinga lokushisa elijwayelekile, umswakama unalo pharamitha, ukukhanya ngokuvamile akunayo le nto.
- Shintsha inani lokulungisa
Okwesiboneloample, inani lamanje lesimo lincane kakhulu, sifuna ukwengeza u-1 kunani layo langempela, futhi inani lamanje kanye nomyalo wokusebenza wokulungisa ongu-100 uthi:01 06 00 6B 00 64 F9 FD.I-ID yedivayisi I-id yomsebenzi Qala Ikheli Indawo oya kuyo CRC16 01 06 00 6b 00 64 F9 FD
- Funda Inani Lokulungisa
Ngemuva kokuthi ukusebenza kuphumelele, idivayisi izobuyisela ulwazi: 01 06 00 6B 00 64 F9 FD, amapharamitha aqala ukusebenza ngokushesha ngemva koshintsho oluyimpumelelo.
Okwesiboneloample, ububanzi bungu-30~130dB, okukhiphayo kwe-analog ngu-0~3V voltage isignali, umsindo kanye voltage Ubudlelwano bokubala bunjengoba kukhonjisiwe kufomula: C = (A2-A1) * (X-B1) / (B2-B1) + A1, lapho u-A2 engumkhawulo ophezulu webanga lomsindo, u-A1 umkhawulo ophansi wobubanzi, B2 ivolumutagIbanga eliphumayo elingu-e liphezulu umkhawulo, u-B1 umkhawulo ophansi, u-X inani lomsindo ofundwayo njengamanje, futhi u-C uyivolumu ebaliwetage value. Uhlu lwamanani asetshenziswa kakhulu lumi kanje:
| ivolumutage (V) | NoiseValue (dB) | Inqubo yokubala |
| 0 | 30.0 | (130-30)*(0-0)÷(3-0)+30 |
| 1 | 63.3 | (130-30)*(1-0)÷(3-0)+30 |
| 2 | 96.7 | (130-30)*(2-0)÷(3-0)+30 |
| 3 | 130.0 | (130-30)*(3-0)÷(3-0)+30 |
Njengoba kukhonjisiwe kufomula engenhla, uma kulinganiswa u-1.5V, current-voltagngi 50db
Umshwana wokuzihlangula
Lo mbhalo unikeza lonke ulwazi ngomkhiqizo, awunikezi noma iyiphi ilayisensi yempahla yengqondo, awuvezi noma usikisela, futhi uvimbela noma yiziphi ezinye izindlela zokunikeza noma imaphi amalungelo empahla yengqondo, njengesitatimende semigomo nemibandela yokuthengisa yalo mkhiqizo, okunye. izindaba. Asikho isikweletu esithathwayo. Ngaphezu kwalokho, inkampani yethu ayenzi ziqinisekiso, ezivezwayo noma ezishiwo, mayelana nokudayiswa nokusetshenziswa kwalo mkhiqizo, okuhlanganisa ukufaneleka kokusetshenziswa okuthile komkhiqizo, ukudayiswa noma isikweletu sokwephulwa kwanoma yiliphi ilungelo lobunikazi, ilungelo lobunikazi noma amanye amalungelo empahla yobuhlakani, njll. . Ukucaciswa komkhiqizo nezincazelo zomkhiqizo zingashintshwa nganoma yisiphi isikhathi ngaphandle kwesaziso.
