Kukurukurirana Protocol
Chigadzirwa chinoshandisa RS485 MODBUS-RTU yakajairwa protocol fomati, ese mashandisirwo kana mirairo yekupindura ndeye hexadecimal data. Iyo kero yekusarudzika kero ndeye 1 kana mudziyo uchitumirwa, iyo default baud rate ndeye 9600, 8, n, 1.
- Verenga Data (Function id 0x03)
Kubvunza furemu (hexadecimal), kutumira example: Mubvunzo 1# mudziyo 1 data, iyo komputa inotumira inotumira murairo:01 03 00 00 00 01 84 0A .ID yemudziyo Basa id Kutanga Kero Data Kureba CRC16 01 03 00 00 00 01 84 0A Kune iyo chaiyo yemubvunzo furemu, mudziyo uchapindura nedata: 01 03 02 00 79 79 A6 , chimiro chemhinduro chinopatsanurwa sezvizvi:
ID yemudziyo Basa id Data Kureba 数据 1 Tarisa Code 01 03 02 00 79 79 A6 Tsanangudzo yedata: Iyo data iri mukuraira ndeye hexadecimal. Tora data 1 se example. 00 79 inoshandurwa kuita decimal value ye 121. Kana iyo data magnification iri 100, kukosha chaiko ndeye 121/100 = 1.21. Vamwe uye zvichingodaro.'

- Verenga kana kubvunza kero yemudziyo
Kana iwe usingazive kero yemudziyo iripo uye pane mudziyo mumwe chete mubhazi, unogona kushandisa murairo FA 03 00 64 00 02 90 5F Query mudziyo kero.ID yemudziyo Basa id Kutanga Kero Data Kureba CRC16 FA 03 00 64 00 02 90 5F FA i250 yekero yakajairika. Kana iwe usingazive kero, unogona kushandisa 250 kuwana iyo chaiyo mudziyo kero, 00 64 ndiyo mudziyo wemodhi rejisita.
Nekuda kwemubvunzo chaiwo murairo, mudziyo uchapindura, semuenzanisoample data remhinduro ndeiyi: 01 03 02 07 12 3A 79, manyorerwo ayo anoratidzwa patafura inotevera:ID yemudziyo Basa id Kutanga Kero Model Code CRC16 01 03 02 55 3C 00 01 3A 79 Mhinduro inofanira kunge iri mudhata, yekutanga byte 01 inoratidza kuti kero chaiyo yemudziyo wazvino, 55 3C yakashandurwa kuita decimal 20182 inoratidza kuti yazvino mudziyo main modhi ndeye 21820, maviri ekupedzisira byte 00 01 Inoratidza kuti mudziyo une chimiro uwandu.
- Chinja kero yemudziyo
For example, kana ikozvino kero yemudziyo iri 1, tinoda kuchinja kuti 02, mutemo unoti: 01 06 00 66 00 02 E8 14.ID yemudziyo Basa id Kutanga Kero Destination CRC16 01 06 00 66 00 02 E8 14 Mushure mokunge shanduko yabudirira, chigadzirwa chichadzorera ruzivo: 02 06 00 66 00 02 E8 27 , chimiro chayo chinoparadzaniswa sezvinoratidzwa mutafura inotevera:
ID yemudziyo Basa id Kutanga Kero Destination CRC16 01 06 00 66 00 02 E8 27 Mhinduro inofanira kunge iri mudhata, mushure mekugadzirisa kwabudirira, yekutanga byte ndiyo kero yemudziyo mutsva. Mushure mekunge kero yedhizaini yashandurwa, ichaita nekukurumidza. Panguva ino, mushandisi anofanira kushandura murairo wemubvunzo wesoftware panguva imwe chete.
- Verenga kana kubvunza kero yemudziyo
- Verenga uye Shandura Baud Rate
- Verenga baud rate
Iyo dhizaini yakasarudzika fekitori baud mwero ndeye 9600. Kana iwe uchida kuichinja, unogona kuichinja maererano netafura inotevera uye inoenderana yekutaurirana protocol. For example, verenga ikozvino mudziyo webaud rate ID, murairo unoti: 01 03 00 67 00 01 35 D5 , chimiro chayo chinoparadzaniswa sezvinotevera.ID yemudziyo Basa id Kutanga Kero Data Kureba CRC16 01 03 00 67 00 01 35 D5 Verenga iyo baud rate encoding yechishandiso chazvino. Baud rate encoding: 1 ndeye 2400; 2 i4800; 3 i9600; 4 ndeye 19200; 5 i38400; 6 i115200.
Nekuda kwemubvunzo chaiwo murairo, mudziyo uchapindura, semuenzanisoample data remhinduro ndeiyi: 01 03 02 00 03 F8 45, manyorerwo ayo anoratidzwa patafura inotevera:ID yemudziyo Basa id Data Kureba Rate ID CRC16 01 03 02 00 03 F8 45 coded zvinoenderana nebaud rate, 03 i9600, kureva kuti mudziyo wazvino une baud rate ye9600.
- Shandura chiyero chebhadhi
For example, kushandura chiyero chebaud kubva pa9600 kuenda pa38400, kureva kuchinja kodhi kubva pa3 kuenda pa5, murairo ndewekuti: 01 06 00 67 00 05 F8 1601 03 00 66 00 01 64 15.ID yemudziyo Basa id Kutanga Kero Target Baud Rate CRC16 01 03 00 66 00 01 64 15 Shandura chiyero chebhadhi kubva ku9600 kusvika ku38400, kushandura kodeti kubva ku3 kusvika ku 5. Mutsva mutsva webhadha unotanga kushanda pakarepo, panguva iyo chigadziro chicharasikirwa nekupindura kwayo uye chiyero chebhadhi chechigadziro chinofanira kubvunzwa maererano. Modified.
- Verenga baud rate
- Verenga Kururamisa Kukosha
- Verenga Kururamisa Kukosha
Kana paine chikanganiso pakati pe data nereferensi chiyero, tinogona kuderedza kukanganisa kwekuratidzira nekugadzirisa kukosha kwekugadzirisa. Musiyano wekugadzirisa unogona kuchinjwa kuti uwedzere kana kubvisa 1000, t hat ndeyekuti, kukosha kwepakati ndeye 0-1000 kana 64535 -65535. For example, kana kukosha kwekuratidzira kuri kudiki, tinogona kuigadzirisa nekuwedzera 100. Murairo ndewekuti: 01 03 00 6B 00 01 F5 D6 . Mukuraira 100 ndeye hex 0x64 Kana iwe uchida kuderedza, unogona kuseta kukosha kwakashata, senge -100, inoenderana neiyo hexadecimal kukosha kweFF 9C, inoverengerwa se 100-65535 = 65435, uye yoshandurwa kuita hexadecimal ku. 0x FF 9C. Iko kukosha kwekugadzirisa kunotanga kubva ku00 6B. Isu tinotora yekutanga parameter se example. Iyo yekururamisa kukosha inoverengwa uye inogadziriswa nenzira imwechete kune akawanda ma paramita.ID yemudziyo Basa id Kutanga Kero Data Kureba CRC16 01 03 00 6B 00 01 F5 D6 Nekuda kwemubvunzo chaiwo murairo, mudziyo uchapindura, semuenzanisoample data remhinduro ndeiyi: 01 03 02 00 64 B9 AF, chimiro chayo sezviri kuratidzwa patafura inotevera:
ID yemudziyo Basa id Data Kureba Data value CRC16 01 03 02 00 64 B9 AF Mune data yekupindura, yekutanga byte 01 inoratidza kero chaiyo yechigadzirwa chazvino, uye 00 6B ndiyo yekutanga mamiriro ehuwandu hwekugadzirisa kukosha kwerejista. Kana mudziyo uine akawanda ma parameter, mamwe ma parameter anoshanda nenzira iyi. Zvakafanana, tembiricha yakajairika, humidity ine iyi parameter, mwenje kazhinji hauna chinhu ichi.
- Shandura kukosha kwekugadzirisa
For example, huwandu hwemamiriro ehurumende huri hudiki, tinoda kuwedzera 1 kune kukosha kwayo kwechokwadi, uye kukosha kwezvino kuwedzera 100 kugadzirisa murairo wekushanda ndeye: 01 06 00 6B 00 64 F9 FD.ID yemudziyo Basa id Kutanga Kero Destination CRC16 01 06 00 6B 00 64 F9 FD
- Verenga Kururamisa Kukosha
Mushure mokunge kushanda kwabudirira, chigadziro chichadzorera ruzivo: 01 06 00 6B 00 64 F9 FD, maparameter anotanga kushanda pakarepo mushure mekuchinja kwakabudirira.
For example, huwandu huri 30 ~ 130dB, iyo analogi inobuda ndeye 0 ~ 3V voltage chiratidzo, ruzha uye voltage Hukama hwekuverenga hunoratidzwa mune fomula: C = (A2-A1) * (X-B1) / (B2-B1) + A1, uko A2 iri ruzha rwepamusoro muganhu, A1 ndiyo yakaderera muganho werudzi, B2 iri voltage inobuda muganho wepamusoro, B1 ndiyo yakaderera muganho, X ndiyo ikozvino inoverengwa ruzha kukosha, uye C ndiyo yakaverengerwa vol.tage value. Rondedzero yezvinonyanya kushandiswa ndeiyi:
| voltage (V) | noiseValue (dB) | Calculation Process |
| 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 |
Sezvinoratidzwa mufomula iri pamusoro, pakuyera 1.5V, ikozvino-voltaguye 50db
