01 06 00 00 E8 14 Tom qab qhov kev hloov pauv tau ua tiav, lub cuab yeej yuav rov qab cov ntaub ntawv: 02 06 00 66 00 02 E8 27, nws hom ntawv tau txheeb raws li qhia hauv qab no:
Ntaus ID Function id Pib Chaw Nyob Qhov chaw CRC 16 01 06 00 00 E8 27 Cov lus teb yuav tsum yog nyob rau hauv cov ntaub ntawv, tom qab kev hloov kho tiav, thawj byte yog qhov chaw nyob tshiab. Tom qab qhov chaw nyob dav dav hloov pauv, nws yuav siv tam sim ntawd. Lub sijhawm no, tus neeg siv yuav tsum hloov cov lus nug ntawm cov software tib lub sijhawm.
- Nyeem thiab hloov pauv tus nqi Baud
(1). Nyeem baud rate
Tus ntaus ntawv lub Hoobkas baud tus nqi yog 9600. Yog tias koj xav tau hloov nws, koj tuaj yeem hloov nws raws li cov lus hauv qab no thiab cov txheej txheem sib txuas lus. Rau example, nyeem cov cuab yeej tam sim no tus baud tus nqi ID, cov lus txib yog: 01 03 00 67 00 01 35 D5, thiab nws cov hom ntawv yog parsed raws li hauv qab no.Ntaus ID
Function id Pib Chaw Nyob Cov Ntaub Ntawv Ntev CRC 16
01 03 00 00 35d 5 Nyeem baud tus nqi encoding ntawm lub cuab yeej tam sim no. Baud tus nqi encoding: 1 yog 2400; 2 yog 4800; 3 yog 9600;. 4 yog 19200; 5 yog 38400; 6 yog 115200.
Rau cov lus nug kom raug, lub cuab yeej yuav teb, piv txwv liample, cov ntaub ntawv teb yog 01 03 02 00 03 F8 45, hom ntawv uas yog raws li qhia hauv cov lus hauv qab no:Ntaus ID
Function id Cov Ntaub Ntawv Ntev Tus nqi ID CRC 16
01 03 02 00 f8 45 ua coded raws li baud tus nqi, 03 yog 9600, piv txwv li cov cuab yeej tam sim no muaj baud tus nqi ntawm 9600.
(2). Hloov tus nqi baud
Rau example, hloov tus nqi baud ntawm 9600 mus rau 38400, piv txwv li hloov cov cai ntawm 3 mus rau 5, cov lus txib yog 01 06 00 67 00 05 F8 1601 03 00 66 00 01 64 15.Ntaus ID
Function id Pib Chaw Nyob Lub hom phiaj Baud Rate CRC 16
01 03 00 00 64 Hloov tus nqi baud ntawm 9600 mus rau 38400, hloov cov cai los ntawm 3 mus rau 5. Tus nqi baud tshiab yuav siv tam sim ntawd, thaum lub sij hawm lub cuab yeej yuav poob nws cov lus teb thiab baud tus nqi ntawm cov cuab yeej yuav tsum tau nug raws li. Hloov kho.
- Nyeem Kev Kho Tus Nqi
(1). Nyeem Kev Kho Tus Nqi
Thaum muaj qhov yuam kev ntawm cov ntaub ntawv thiab cov qauv siv, peb tuaj yeem txo qhov kev ua yuam kev los ntawm kev kho tus nqi kho. Kev kho qhov sib txawv tuaj yeem hloov tau los ua ntxiv lossis rho tawm 1000, uas yog, tus nqi ntau yog 0-1000 lossis 64535 -65535. Rau example, thaum tus nqi zaub me dhau, peb tuaj yeem kho nws los ntawm kev ntxiv 100. Cov lus txib yog: 01 03 00 6B 00 01 F5 D6 . Hauv qhov hais kom ua 100 yog hex 0x64 Yog tias koj xav tau txo, koj tuaj yeem teeb tsa tus nqi tsis zoo, xws li -100, sib haum rau tus nqi hexadecimal ntawm FF 9C, uas yog xam raws li 100-65535 = 65435, thiab tom qab ntawd hloov mus rau hexadecimal rau 0 x f9c. Tus nqi kho yog pib ntawm 00 6B. Peb coj thawj parameter ua ib qho example. Tus nqi kho yog nyeem thiab hloov kho tib yam rau ntau yam tsis muaj.Ntaus ID
Function id Pib Chaw Nyob Cov Ntaub Ntawv Ntev CRC 16
01 03 00b ib 00 F5 D6 Rau cov lus nug kom raug, lub cuab yeej yuav teb, piv txwv liample, cov ntaub ntawv teb yog 01 03 0200 64 B9 AF, hom ntawv uas tau qhia hauv cov lus hauv qab no:
Ntaus ID Function id Cov Ntaub Ntawv Ntev Cov ntaub ntawv tus nqi CRC 16 01 03 02 00 AB 9 AF Hauv cov ntaub ntawv teb, thawj byte 01 qhia qhov chaw nyob ntawm lub cuab yeej tam sim no, thiab 00 6B yog thawj lub xeev cov nqi kho tus nqi sau npe. Yog tias lub cuab yeej muaj ntau qhov tsis sib xws, lwm yam tsis ua haujlwm hauv txoj kev no. Ib yam nkaus, qhov kub thiab av noo muaj qhov ntsuas no, lub teeb feem ntau tsis muaj cov khoom no.
(2). Hloov kho tus nqi
Rau example, yog tias lub xeev tam sim no muaj tsawg dhau, peb xav ntxiv 1 rau nws qhov tseeb tus nqi, thiab tus nqi tam sim no ntxiv rau 100 kev kho cov lus txib yog: 01 06 00 6B 00 64 F9 FD.Ntaus ID
Function id Pib Chaw Nyob Qhov chaw CRC 16
01 06 00b ib 00 F9 FD Tom qab kev ua haujlwm tiav, lub cuab yeej yuav rov qab cov ntaub ntawv: 01 06 00 6B 00 64 F9 FD, cov kev txwv yuav siv tam sim tom qab kev hloov pauv tiav.
Rau example, qhov ntau yog 0 ~ 50ppm, cov zis analog yog 4 ~ 20mA tam sim no teeb liab, carb ntawm dioxide thiab tam sim no Cov kev sib raug zoo ntawm kev suav yog raws li qhia hauv cov mis: C = (A2 -A1) * (X-B1) / (B2 -B1) + A1, qhov twg A2 yog cov pa roj carbon dioxide ntau qhov txwv, A1 yog qis dua ntawm qhov ntau, B2 yog tam sim no tso zis ntau qhov txwv, B1 yog qis dua, X yog tam sim no nyeem carbon dioxide tus nqi, thiab C yog xam tus nqi tam sim no.
Cov npe ntawm cov txiaj ntsig uas nquag siv yog raws li hauv qab no:Tam sim no (mA) carbon dioxide tus nqi (ppm) Cov txheej txheem suav 4 0.0 (50-0)*(4-4)÷(20-4)+0 5 3.1 (50-0)*(5-4)÷(20-4)+0 6 6.3 (50-0)*(6-4)÷(20-4)+0 7 9.4 (50-0)*(7-4)÷(20-4)+0 8 12.5 (50-0)*(8-4)÷(20-4)+0 9 15.6 (50-0)*(9-4)÷(20-4)+0 10 18.8 (50-0)*(10-4)÷(20-4)+0 11 21.9 (50-0)*(11-4)÷(20-4)+0 12 25.0 (50-0)*(12-4)÷(20-4)+0 13 28.1 (50-0)*(13-4)÷(20-4)+0 14 31.3 (50-0)*(14-4)÷(20-4)+0 15 34.4 (50-0)*(15-4)÷(20-4)+0 16 37.5 (50-0)*(16-4)÷(20-4)+0 17 40.6 (50-0)*(17-4)÷(20-4)+0 18 43.8 (50-0)*(18-4)÷(20-4)+0 19 46.9 (50-0)*(19-4)÷(20-4)+0 20 50.0 (50-0)*(20-4)÷(20-4)+0 Raws li pom hauv cov qauv saum toj no, thaum ntsuas 8mA, qhov tam sim no yog 16 .5ppm.
Rau example, qhov ntau yog 0 ~ 50ppm, analog tso zis yog 0 ~ 5V DC0-5Vvoltage teeb liab, carbon dioxide, thiab DC0-5Vvoltage Kev sib raug zoo ntawm kev suav yog raws li qhia hauv cov qauv: C = (A2 -A1) * (X-B1) / (B2-B1) + A1, qhov A2 yog carbon dioxide ntau qhov txwv, A1 yog qhov qis qis ntawm qhov ntau , B2 yog DC0-5Vvoltage tso zis ntau qhov txwv siab, B1 yog qhov txwv qis, X yog tam sim no nyeem cov pa roj carbon dioxide tus nqi, thiab C yog xam DC0-5Vvoltage nqi. Cov npe ntawm cov txiaj ntsig uas nquag siv yog raws li hauv qab no:DC0-5V Voltage (V) carbon dioxide tus nqi (ppm) Cov txheej txheem suav 0 0.0 (50-0)*(0-0)÷(5-0)+0 1 10.0 (50-0)*(1-0)÷(5-0)+0 2 20.0 (50-0)*(2-0)÷(5-0)+0 3 30.0 (50-0)*(3-0)÷(5-0)+0 4 40.0 (50-0)*(4-0)÷(5-0)+0 5 50.0 (50-0)*(5-0)÷(5-0)+0 Raws li pom hauv cov qauv saum toj no, thaum ntsuas 2.5V, tam sim no DC0-5Vvoltagib 25ppm
