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.
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 .
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.
2. Data Kero Tafura
3 verenga uye gadzirisa kero yemuchina
(1) Verenga kana kubvunza kero yemuchina
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.
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.
(2)Chinja kero yemuchina
For example, kana ikozvino kero yemudziyo iri 1, tinoda kuchinja ku02, murairo unoti: 01 06 00 66 00 02 E8 14 .
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.
4 Verenga uye Shandura Baud Rate
(1) Verenga mwero wemhashu
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.
(2) Shandura chiyero chebaud
For example, kushandura chiyero chebaud kubva pa9600 kuenda ku38400, kureva kushandura kodhi kubva pa3 kuenda ku5, murairo unoti: 01 06 00 67 00 05 F8 1601 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.
5 Verenga Ukoshi Hwokururamisa
(1) Verenga Kururamisa Ukoshi
Kana paine chikanganiso pakati pe data nereference standard, tinogona kudzikisa kukanganisa kwekuratidzira nekugadzirisa kukosha kwekururamisa. Musiyano wekugadzirisa unogona kugadziridzwa kuti uwedzere kana kubvisa 1000, kureva kuti, 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. Iko kukosha kwekugadzirisa kunoverengwa uye kuchinjwa nenzira imwechete kune akawanda ma parameter.
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.
(2) Shandura kukosha kwekururamisa
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 .
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, kubuda kweanalog ndeye 0 ~ 3V DC0 -3Vvoltage chiratidzo, ruzha uye DC0-3Vvoltage Hukama hwekuverenga hunoratidzwa mufomula: C = (A2 -A1) * (X-B1) / (B2-B1) + A1, uko A2 iri ruzha rwepamusoro muganhu, A1 ndiyo yakaderera muganho werudzi, B2 iri DC0 -3Vvoltage inobuda muganho wepamusoro, B1 ndiyo yakaderera muganho, X ndiyo ikozvino inoverengwa ruzha kukosha, uye C ndiyo yakaverengerwa DC0-3Vvol.tage value. Rondedzero yezvinonyanya kushandiswa ndeiyi:
