Communication Protocol
Chogulitsacho chimagwiritsa ntchito mtundu wa RS485 MODBUS-RTU wokhazikika, malamulo onse ogwiritsira ntchito kapena oyankha ndi data ya hexadecimal. Adilesi yokhazikika ya chipangizocho ndi 1 pomwe chipangizocho chimatumizidwa, chiwongola dzanja chokhazikika ndi 9600, 8, n, 1.
Werengani Data (ID ya ntchito 0x03)
Kufunsira chimango (hexadecimal), kutumiza example: Funso 1# chipangizo 1 deta, wolandira kompyuta amatumiza lamulo:01 03 00 00 00 01 84 0A .
| ID ya chipangizo | ID ya ntchito | Adilesi Yoyambira | Kutalika Kwadongosolo | CRC16 |

3 werengani ndikusintha adilesi ya chipangizocho
Werengani kapena funsani adilesi ya chipangizocho
Ngati simukudziwa adiresi yamakono yamakono ndipo pali chipangizo chimodzi chokha pa basi, mungagwiritse ntchito lamulo FA 03 00 64 00 02 90 5F Funso chipangizo adiresi.
| ID ya chipangizo | ID ya ntchito | Adilesi Yoyambira | Kutalika Kwadongosolo | CRC16 |
| FA | 03 | 00 64 | 00 02 | 90 5F |
FA ndi 250 pa adilesi yonse. Mukapanda kudziwa adilesi, mutha kugwiritsa ntchito 250 kuti mupeze adilesi yeniyeni ya chipangizocho, 00 64 ndiye kaundula wachitsanzo cha chipangizocho.
Kuti mupeze lamulo lolondola, chipangizocho chidzayankha, mwachitsanzoample deta yoyankhira ndi: 01 03 02 07 12 3A 79, mawonekedwe ake akuwonetsedwa patebulo ili:
| ID ya chipangizo | ID ya ntchito | Adilesi Yoyambira | Model Kodi | CRC16 |
| 01 | 03 | 02 | 55 3C 00 01 | 3A 79 |
Kuyankha kuyenera kukhala mu data, byte yoyamba 01 ikuwonetsa kuti adilesi yeniyeni ya chipangizochi ndi, 55 3C yosinthidwa kukhala decimal 20182 ikuwonetsa kuti chipangizochi chili ndi 21820, ma byte awiri omaliza 00 01 Akuwonetsa kuti chipangizocho chili ndi kuchuluka kwa udindo.
Sinthani adilesi ya chipangizo
Za example, ngati adilesi yamakono ndi 1, tikufuna kusintha ku 02, lamulo ndi: 01 06 00 66 00 02 E8 14 .
| ID ya chipangizo | ID ya ntchito | Adilesi Yoyambira | Kopita | CRC16 |
| 01 | 06 | 00 66 | 00 02 | E8 14 |
Kusinthako kukachitika bwino, chipangizocho chidzabwezera zambiri: 02 06 00 66 00 02 E8 27 , mawonekedwe ake amagawidwa monga momwe tawonetsera pa tebulo ili:
| ID ya chipangizo | ID ya ntchito | Adilesi Yoyambira | Kopita | CRC16 |
| 01 | 06 | 00 66 | 00 02 | E8 27 |
Kuyankha kuyenera kukhala mu data, pambuyo poti kusinthidwa kukuyenda bwino, byte yoyamba ndi adilesi yatsopano ya chipangizocho. Adilesi ya chipangizo ikasinthidwa, iyamba kugwira ntchito nthawi yomweyo. Panthawiyi, wosuta ayenera kusintha lamulo lafunso la pulogalamuyo nthawi yomweyo.
Werengani ndi Kusintha Baud Rate
Werengani mlingo wa baud
Chipangizo chokhazikika cha fakitale ya baud ndi 9600. Ngati mukufuna kusintha, mukhoza kusintha malinga ndi tebulo ili ndi ndondomeko yolumikizirana. Za example, werengani ID ya curren t chipangizo cha baud, lamulo ndi: 01 03 00 67 00 01 35 D5 , mawonekedwe ake amagawidwa motere.
| ID ya chipangizo | ID ya ntchito | Adilesi Yoyambira | Kutalika Kwadongosolo | CRC16 |
| 01 | 03 | 00 67 | 00 01 | 35d5 ndi |
Werengani ma encoding a baud rate pa chipangizo chomwe chilipo. Baud rate encoding: 1 ndi 2400; 2 ndi 4800; 3 ndi 9600; 4 ndi 19200; 5 ndi 38400; 6 ndi 115200.
Kuti mupeze lamulo lolondola, chipangizocho chidzayankha, mwachitsanzoample deta yoyankhira ndi: 01 03 02 00 03 F8 45, mawonekedwe ake akuwonetsedwa patebulo lotsatirali:
| ID ya chipangizo | ID ya ntchito | Kutalika Kwadongosolo | Mtengo ID | CRC16 |
| 01 | 03 | 02 | 00 03 | pa f8 |
zolembedwa molingana ndi kuchuluka kwa baud, 03 ndi 9600, mwachitsanzo, chipangizo chapano chili ndi chiwopsezo cha 9600.
Kusintha mlingo wa baud
Za example, kusintha mlingo wa baud kuchokera 9600 kuti 38400, mwachitsanzo kusintha kachidindo kuchokera 3 mpaka 5, lamulo ndi: 01 06 00 67 00 05 F8 1601 03 00 66 00 01 64 15 .
| ID ya chipangizo | ID ya ntchito | Adilesi Yoyambira | Target Baud Rate | CRC16 |
| 01 | 03 | 00 66 | 00 01 | 64 15 |
Sinthani mlingo wa baud kuchokera ku 9600 kupita ku 38400, kusintha kachidindo kuchokera ku 3 mpaka 5. Mlingo watsopano wa baud udzachitika nthawi yomweyo, pomwe chipangizocho chidzataya yankho lake ndipo mlingo wa baud wa chipangizocho uyenera kufunsidwa moyenerera. Zosinthidwa.
Werengani Mtengo Wowongolera
Werengani Mtengo Wowongolera
Pakakhala cholakwika pakati pa data ndi mulingo wolozera, titha kuchepetsa cholakwika chowonetsera posintha mtengo wowongolera. Kusiyana kowongolera kumatha kusinthidwa kukhala kuphatikiza kapena kuchotsera 1000, t hat ndi, mtengo wamtengo wapatali ndi 0-1000 kapena 64535 -65535. Za example, pamene mtengo wowonetsera uli wochepa kwambiri, tikhoza kukonza mwa kuwonjezera 100. Lamulo ndi: 01 03 00 6B 00 01 F5 D6 . Mu lamulo 100 ndi hex 0x64 Ngati mukufuna kuchepetsa, mukhoza kukhazikitsa mtengo woipa, monga -100, wolingana ndi mtengo wa hexadecimal wa FF 9C, womwe umawerengedwa ngati 100-65535 = 65435, kenako n'kusinthidwa kukhala hexadecimal to 0x ndi 9C. Mtengo wowongolera umayambira pa 00 6B. Timatenga parameter yoyamba ngati example. Mtengo wowongolera umawerengedwa ndikusinthidwa mofanana ndi magawo angapo.
| ID ya chipangizo | ID ya ntchito | Adilesi Yoyambira | Kutalika Kwadongosolo | CRC16 |
| 01 | 03 | 00 6b ndi | 00 01 | F5 D6 |
Kuti mupeze lamulo lolondola, chipangizocho chidzayankha, mwachitsanzoample deta yoyankha ndi: 01 03 02 00 64 B9 AF, mawonekedwe ake akuwonetsedwa patebulo lotsatirali:
| ID ya chipangizo | ID ya ntchito | Kutalika Kwadongosolo | Mtengo wa data | CRC16 |
| 01 | 03 | 02 | 00 64 | B9 AF |
Mu data yankho, byte yoyamba 01 imasonyeza adiresi yeniyeni ya chipangizo chamakono, ndipo 00 6B ndiye woyamba boma kuchuluka kuwongolera mtengo kaundula. Ngati chipangizocho chili ndi magawo angapo, magawo ena amagwira ntchito motere. Momwemonso, kutentha, chinyezi ndi chizindikiro ichi, kuwala nthawi zambiri kulibe chinthu ichi.
Sinthani mtengo wowongolera
Za example, kuchuluka kwazomwe zikuchitika pano ndi kochepa kwambiri, tikufuna kuwonjezera 1 ku mtengo wake weniweni, ndipo mtengo wapano kuphatikiza 100 kuwongolera opareshoni lamulo ndi:01 06 00 6B 00 64 F9 FD .
| ID ya chipangizo | ID ya ntchito | Adilesi Yoyambira | Kopita | CRC16 |
| 01 | 06 | 00 6b ndi | 00 64 | F9 FD |
Pambuyo pochita bwino, chipangizocho chidzabwezera zambiri: 01 06 00 6B 00 64 F9 FD, magawowa amayamba kugwira ntchito atangosintha bwino.
Za exampLe, mitundu ndi 30 ~ 130dB, kutulutsa kwa analogi ndi 0 ~ 3V DC0-3Vvoltage chizindikiro, phokoso ndi DC0-3Vvoltage Ubale wowerengera ukuwonetsedwa mu chilinganizo: C = (A2-A1) * (X-B1) / (B2-B1) + A1, pomwe A2 ndi malire amtundu wapamwamba, A1 ndiye malire otsika amtunduwu, B2 ndi DC0-3Vvoltage yotulutsa malire apamwamba, B1 ndiye malire otsika, X ndiye phokoso lomwe likuwerengedwa pano, ndipo C ndi DC0-3Vvol yowerengedwatagndi mtengo. Mndandanda wamakhalidwe omwe amagwiritsidwa ntchito kwambiri ndi awa:
| Chithunzi cha DC0-3Vvoltage (V) | NoiseValue (dB) | Njira Yowerengera |
| 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 |
Monga momwe tawonetsera pamwambapa, poyesa 1.5V, DC0-3Vvol yamakonotagndi 50db.
Chodzikanira
Chikalatachi chimapereka zidziwitso zonse zokhudzana ndi malonda, sichipereka chilolezo kuzinthu zanzeru, sichifotokoza kapena kutanthauza, ndipo chimaletsa njira zina zilizonse zoperekera ufulu wazinthu zamaluntha, monga mawu a malonda ndi zikhalidwe za chinthuchi, zina. nkhani. Palibe mlandu womwe umaganiziridwa. Kuphatikiza apo, kampani yathu sipereka zitsimikizo, zofotokozera kapena kutanthauza, zokhuza kugulitsa ndi kugwiritsa ntchito chinthuchi, kuphatikiza kuyenera kugwiritsidwa ntchito kwa chinthucho, kugulitsa kapena kuphwanya udindo wapatent, kukopera kapena maufulu ena aluntha, ndi zina. . Mafotokozedwe azinthu ndi mafotokozedwe azinthu zitha kusinthidwa nthawi iliyonse popanda chidziwitso.
