Umfanekiso 5 4-20mA uxhumano
Ithuluzi lingabonisa okungenani inkomba yenani legesi eyodwa.Uma inkomba yegesi ezotholwa iku-alamu, ukudluliselwa kuzovalwa.Uma kusetshenziswa isibani se-alamu yomsindo nesikhanyayo, i-alamu yomsindo neyokukhanya izothunyelwa.
Insimbi inezindawo ezintathu zokukhanya zomsindo kanye neswishi eyodwa ye-LCD.
Ithuluzi linomsebenzi wesitoreji sesikhathi sangempela, esingarekhoda isimo se-alamu nesikhathi ngesikhathi sangempela.Sicela ubheke imiyalelo elandelayo ukuze uthole ukusebenza okuqondile kanye nencazelo yomsebenzi.
3.1 Incazelo esemqoka
Insimbi inezinkinobho ezintathu, futhi imisebenzi ikhonjiswe kuThebula lesi-3
Ithebula 3 incazelo yokhiye
| Ukhiye | Umsebenzi | Ukuphawula |
| KEY1 | Ukukhetha imenyu | Ukhiye wesokunxele |
| KEY2 | Faka imenyu bese uqinisekisa inani lokusetha | Ukhiye ophakathi |
| KEY3 | Buka amapharamitha Ukufinyelela kumsebenzi okhethiwe | Ukhiye wesokudla |
Qaphela: eminye imisebenzi ingaphansi kwesibonisi esingezansi kwesikrini sensimbi.
Ingase futhi isetshenziswe ngesilawuli kude se-infrared.Umsebenzi obalulekile wesilawuli kude se-infrared uboniswa kuMfanekiso 6.
Umfanekiso 6 izincazelo zokhiye wesilawuli kude
3.2 Isibonisi esibonakalayo
Ngemva kokuthi ithuluzi livuliwe, faka isibonisi sokubonisa ebhuthini.Njengoba kuboniswe kuMfanekiso 7:
Umdwebo 7 wesibonisi sokuqalisa
Lesi sixhumanisi siwukulinda amapharamitha wensimbi ukuthi azinze.Ibha yokuskrola emaphakathi ne-LCD ikhombisa isikhathi sokulinda, cishe ama-50s.I-X% ukuqhubeka kokusebenza kwamanje.Ekhoneni elingezansi kwesokudla lesibonisi isikhathi sensimbi yamanje (lokhu kungashintshwa njengoba kudingeka kumenyu).
Uma iphesenti lesikhathi sokulinda lingu-100%, ithuluzi lizofaka isixhumi esibonakalayo sokuqapha igesi.Thatha i-carbon monoxide njengesibonelo, njengoba kukhonjisiwe kuMfanekiso 8.
Umfanekiso 8 wokuqapha izibonisi zegesi
Uma udinga ukubuka imingcele yegesi, chofoza inkinobho yesokudla.
1) Ukubona isibonisi esibonakalayo:
Bonisa: uhlobo lwegesi, inani lokuhlushwa kwegesi, iyunithi, isimo.Njengoba kuboniswe kuMfanekiso 8.
Uma igesi idlula okuhlosiwe, uhlobo lwe-alamu lweyunithi luzoboniswa ngaphambi kweyunithi (uhlobo lwe-alamu lwe-carbon monoxide, i-hydrogen sulfide negesi evuthayo yileveli 1 noma ileveli 2, kuyilapho uhlobo lwe-alamu lomoya-mpilo umkhawulo ophezulu noma ophansi), njengoba kukhonjisiwe kuMfanekiso 9.
Isithombe 9 esibonakalayo esine-alamu yegesi
1) Ipharamitha yokubonisa isikhombimsebenzisi:
Kusixhumi esibonakalayo sokubona igesi, chofoza kwesokudla ukuze ufake isixhumi esibonakalayo sepharamitha yegesi.
Bonisa: uhlobo lwegesi, isimo se-alamu, isikhathi, inani le-alamu lezinga lokuqala (i-alamu yomkhawulo ophansi), inani le-alamu lezinga lesibili (i-alamu yomkhawulo ophezulu), ububanzi, inani lamanje lokugxiliswa kwegesi, iyunithi, indawo yegesi.
Uma ucindezela ukhiye (ukhiye wesokudla) ngaphansi kokuthi “buyisela”, isixhumi esibonakalayo sizoshintshela kusixhumi esibonakalayo sokutholwa kwegesi.
