Isetshenziswa kanjani? 
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 | Idatha ye-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

3 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 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 ye-curren t, 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 Inani Lokulungisa
Funda Inani Lokulungisa
Uma kunephutha phakathi kwedatha nezinga lereferensi, singehlisa iphutha lesibonisi ngokulungisa inani lokulungisa. Umehluko wokulungisa ungashintshwa ube ukuhlanganisa noma kususe 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 |
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 DC0-3Vvoltagisignali ye-e, umsindo kanye ne-DC0-3Vvoltage 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, I-B2 ingu-DC0-3VvoltagIbanga lokukhiphayo elingu-e liphezulu, u-B1 umkhawulo ophansi, u-X inani lomsindo ofundwayo njengamanje, futhi u-C uyi-DC0-3Vvol ebaliwetage value. Uhlu lwamanani asetshenziswa kakhulu lumi kanje:
| I-DC0-3Vvoltage (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, lapho kulinganiswa i-1.5V, i-DC0-3Vvol yamanjetagngi 50dB.
