Ipine Ubwoko bwa Digital Yarn Ubushuhe

Ipine Ubwoko bwa Digital Yarn Ubushuhe bwa Metero,
Ubushinwa Ubushuhe bw'ubushuhe hamwe n'uburebure bw'umusenyi,

Ubushuhe bw'ubutaka:
Ubwoko bwa voltage (0 ～ 5V ibisohoka):
R = V / 5 × 100%
(R nigiciro cyubutaka bwubutaka na V nigisohoka voltage agaciro (V))
Ubwoko bwa none (4 ～ 20mA ibisohoka):
R = (I-4) / 16 × 100%
(R nigiciro cyubutaka bwubutaka, Ninjye usohoka agaciro (mA))

Ubushyuhe bwubutaka:
Ubwoko bwa voltage (0 ～ 5V ibisohoka):
T = V / 5 × 70-20
.
Ubwoko bwa none (4 ～ 20mA)
T = (I-4) / 16 × 70 -20
.

1.Niba ufite ibikoresho byikirere byakozwe nisosiyete, huza byimazeyo sensor nu murongo uhuye na sitasiyo yikirere ukoresheje umurongo wa sensor;

2. Niba imiyoboro yaguzwe ukwayo, umurongo ujyanye numurongo wohereza ni:

Umuyoboro wa transmitter hamwe nibisohoka wiring:

Wiring ya voltage isohoka muburyo

Icyitonderwa

Kubara code ya CRC:
1.Kwiyandikisha mbere ya 16-bit ni FFFF muri hexadecimal (ni ukuvuga, bose ni 1).Hamagara iyi rejisitiri igitabo cya CRC.
2.XOR amakuru yambere 8-biti hamwe na bito yo hasi ya 16-biti ya CRC hanyuma ushire ibisubizo mubitabo bya CRC.
3.Hindura ibiri muri rejisitiri iburyo na bito imwe (werekeza kuri bito), wuzuze bito na 0, hanyuma urebe bito yo hasi.
4.Niba bito bito cyane ari 0: subiramo intambwe ya 3 (ongera uhindure), niba bito bito byingenzi ari 1: igitabo cya CRC ni XORed hamwe na polinomial A001 (1010 0000 0000 0001).
5.Subiramo intambwe 3 na 4 kugeza inshuro 8 iburyo, kugirango amakuru 8-bit yose yatunganijwe.
6.Subiramo intambwe ya 2 kugeza kuri 5 yo gutunganya amakuru 8-bitaha.
7.CRC kwiyandikisha amaherezo yabonetse ni code ya CRC.
8.Iyo CRC ibisubizo ishyizwe mumakuru yamakuru, hejuru na bito bito birahanahana, kandi bito ni mbere.

Huza sensor ukurikije amabwiriza yuburyo bwo gukoresha insinga, hanyuma ushyiremo pine ya probe ya sensor mu butaka kugirango upime ubuhehere, hanyuma ufungure ingufu hamwe na kolitori ihinduranya kugirango ubone ubushyuhe bwubutaka nubushuhe aho bipimirwa.

1.Nyamuneka reba niba ibipfunyitse bidahwitse kandi urebe niba ibicuruzwa byerekana ibicuruzwa bihuye no guhitamo.
2.Ntugahuze nimbaraga kuri, hanyuma imbaraga kuri nyuma yo kugenzura insinga.
3.Ntugahindure uko bishakiye ibice cyangwa insinga byagurishijwe mugihe ibicuruzwa biva muruganda.
4.Rukuruzi ni igikoresho gisobanutse.Nyamuneka ntukayisenye wenyine cyangwa ngo ukore hejuru ya sensor hamwe nibintu bikarishye cyangwa amazi yangirika kugirango wirinde kwangiza ibicuruzwa.
5.Nyamuneka komeza icyemezo cyo kugenzura nicyemezo cyo guhuza, hanyuma usubize nibicuruzwa mugihe cyo gusana.

1.Iyo ibisohoka byamenyekanye, kwerekana byerekana ko agaciro ari 0 cyangwa kari kure.Reba niba hari inzitizi ziva mubintu byamahanga.Uwatoraguye ntashobora kubona amakuru neza kubera ibibazo byinsinga.Nyamuneka reba niba insinga ari nziza kandi ihamye;
2. Niba atariyo mpamvu zavuzwe haruguru, nyamuneka hamagara uwagikoze.
