Pin Type Digital Yarn Moisture Meter

Pin Type Digital Yarn Moisture Meter,
China Moisture Meter ndi Sand Moisture Meter,

Chinyezi cha nthaka:
Mtundu wamagetsi (0 ~ 5V kutulutsa):
R = V / 5 × 100%
(R ndiye chinyezi cha nthaka ndipo V ndi mtengo wamagetsi otulutsa (V))
Mtundu wapano (4 ～ 20mA zotuluka):
R = (I-4) / 16 × 100%
(R ndiye kuchuluka kwa chinyezi cha nthaka, ine ndiye mtengo wapano (mA))

Kutentha kwa nthaka:
Mtundu wamagetsi (0 ~ 5V kutulutsa):
T = V / 5 × 70-20
(T ndiye mtengo woyezera kutentha (℃), V ndi mtengo wamagetsi otulutsa (V), fomula iyi imafanana ndi muyeso woyezera -20 ~ 50 ℃)
Mtundu wapano (4 ～ 20mA)
T = (I-4) / 16 × 70 -20
(T ndiye muyeso woyezera kutentha (℃), Ine ndiye kutulutsa panopa (mA), fomulayi imagwirizana ndi muyeso woyezera -20 ～ 50 ℃)

1.Ngati muli ndi malo opangira nyengo opangidwa ndi kampaniyo, gwirizanitsani kachipangizo kameneka ndi mawonekedwe ogwirizana pa siteshoni ya nyengo pogwiritsa ntchito chingwe cha sensa;

2. Ngati transmitter igulidwa padera, mzere wofananira wa transmitter ndi:

Magetsi a Transmitter ndi mawaya aposachedwa:

Wiring kwa ma voltage output mode

Wiring kwa panopa linanena bungwe mode

Kapangidwe Miyeso

Kukula kwa Sensor

1.Mtundu wa serial

Chongani Digit Palibe
Baud mlingo 9600 Kuyankhulana kwapakati ndi osachepera 1000ms
2.Kuyankhulana kwamtundu
[1] Lembani adilesi ya chipangizo
Tumizani: 00 10 Adilesi CRC (5 mabayiti)
Kubwerera: 00 10 CRC (4 mabayiti)
Zindikirani: 1. Gawo la adilesi ya lamulo lowerengera ndi kulemba liyenera kukhala 00. 2. Adilesi ndi 1 byte ndipo kuchuluka kwake ndi 0-255.
Chitsanzo: Tumizani 00 10 01 BD C0
Kubwerera 00 10 00 7C
[2] Werengani adilesi ya chipangizocho
Tumizani: 00 20 CRC (4 mabayiti)
Kubwerera: 00 20 Adress CRC (5 byte)
Kufotokozera: Adilesi ndi 1 byte, mtundu wake ndi 0-255

Zindikirani

Kuti muwerengere nambala ya CRC:
1.Kaundula wa 16-bit wokonzedweratu ndi FFFF mu hexadecimal (ndiko kuti, onse ndi 1).Imbani kaundulayu kuti kaundula wa CRC.
2.XOR deta yoyamba ya 8-bit yokhala ndi cholembera cha 16-bit CRC ndikuyika zotsatira mu kaundula wa CRC.
3.Sinthani zomwe zili m'kaundula kumanja ndi pang'ono pang'ono (kumunsi pang'ono), lembani kachidutswa kakang'ono kwambiri ndi 0, ndipo onani chotsikitsitsa.
4.Ngati chocheperako ndi 0: bwerezani gawo 3 (sinthaninso), ngati chocheperako ndi 1: kaundula wa CRC ndi XORed ndi polynomial A001 (1010 0000 0000 0001).
5.Bwerezani masitepe 3 ndi 4 mpaka 8 kumanja, kuti deta yonse ya 8-bit yasinthidwa.
6.Bwerezani masitepe 2 mpaka 5 kuti mukonzenso 8-bit data.
7.Regista ya CRC yomwe idapezedwa ndi CRC code.
8.Zotsatira za CRC zikayikidwa muzithunzi zachidziwitso, ma bits apamwamba ndi otsika amasinthidwa, ndipo otsika amakhala oyamba.

Lumikizani sensa molingana ndi malangizo mu njira yolumikizira ma waya, kenaka ikani zikhomo za sensa m'nthaka kuti muyese chinyezi, ndikuyatsa mphamvu ndi chosinthira kuti mupeze kutentha kwa nthaka ndi chinyezi pamalo oyezera.

1.Chonde yang'anani ngati zoyikazo sizili bwino ndikuwona ngati mtundu wa malondawo ukugwirizana ndi zomwe zasankhidwa.
2.Osalumikizana ndi magetsi, ndiyeno yatsani mukayang'ana mawaya.
3.Osasintha mosasamala zinthu kapena mawaya omwe adagulitsidwa pamene katunduyo achoka kufakitale.
4.Sensa ndi chipangizo cholondola.Chonde musamasule nokha kapena kukhudza pamwamba pa sensa ndi zinthu zakuthwa kapena zakumwa zowononga kuti mupewe kuwononga chinthucho.
5.Chonde sungani satifiketi yotsimikizira ndi satifiketi yogwirizana, ndipo mubwezereni ndi katunduyo pokonza.

1.Zotsatira zikapezeka, chiwonetserochi chikuwonetsa kuti mtengo wake ndi 0 kapena wachoka.Onani ngati pali chotchinga kuchokera kuzinthu zakunja.Wosonkhanitsa sangathe kupeza zambiri molondola chifukwa cha vuto la waya.Chonde onani ngati mawayawo ali olondola komanso olimba;
2. Ngati sizili zifukwa zomwe zili pamwambazi, chonde lemberani wopanga.
