Ama-Wire-wire nohlelo lwama-wire-wire amabili wengcindezi yokudlulisa

Iningi leAma-Transmitterszifakwe esizeni, futhi amasiginali abo okuphuma athunyelwa egumbini lokulawula, futhi ukunikezwa kwamandla kwalo kuvela egumbini lokulawula. Kunezindlela ezimbili zokudluliselwa kwesiginali kanye nokunikezwa kwamandla okudlulisela:

(1) Uhlelo olune-Wire

Ukuhlinzekwa kwamandla kanye nesiginali yokuphuma kudluliselwa izintambo ezimbili ngokulandelana, futhi indlela ye-wiring ikhonjiswa kuMfanekiso 2.3. AbakwaTransmitters abanjalo babizwa ngokuthi ama-transmitter amane. Ithuluzi le-Transmit ye-DDZ-ⅱ Series lamukela le ndlela ye-wiring.Since Amandla nesiginali adluliselwa ngokwahlukana, azikho izidingo eziqinile kwiphuzu le-zero le-Iro Point. Ukuhlinzekwa kwamandla kungaba yi-AC (220V) noma i-DC (24V), kanye nesiginali yokuphuma kungaba efile zero (0-10m) noma bukhoma (4-20ma).

Umdwebo 2.3 Ukuhanjiswa okune-wire

(1) Uhlelo lwe-Wire-Wire

Okokudluliselwa kwe-wire-wire, kunamawazi amabili kuphela axhumekile ku-transmitter, futhi lezi zintambo ezimbili zidlulisela ukulethwa kwamandla kanye nokuphuma kwesiginali ngasikhathi sinye, njengoba kukhonjisiwe kuMfanekiso 2.4. Kungabonakala ukuthi ukunikezwa kwamandla, ukudlulisela kanye nokulayishwa kokulayishwa kuxhunyiwe kuchungechunge.I-transmitter e-wire-wire ilingana nokuphikiswa okuguqukayo okulawulwa yipharamitha elinganiselwe. Lapho ipharamitha elinganisiwe lishintsha, ukumelana okulinganayo komdlulisi kushintsha ngokufanele, ngakho-ke okugeleza kwamanje ngomthwalo kuyashintsha.

Umdwebo 2.4 Ukuhanjiswa okubili ngocingo

Ama-transmitters amabili-wire kumele ahlangabezane nalezi zimo ezilandelayo:

①Ukusebenza okujwayelekile kwamanje kwe-transmitter kufanele kulingane noma ngaphansi kwenani eliphansi le-signal yamanje

,Leyo

Njengoba umugqa wamandla nomugqa wesiginali uvamile, amandla anikezwe umdluliseli ngamandla kagesi anikezwa isiginali yamanje. Lapho umphumela wamanje we-transmitter usemkhawulweni ophansi, kufanele uqinisekiswe ukuthi amadivayisi we-semiconductor ngaphakathi kusasebenza ngokujwayelekile.

Ngakho-ke, inani eliphansi lomkhawulo wesiginali okwamanje alikwazi ukuba liphansi kakhulu. Ngoba emkhawulweni ophansi wokukhishwa kwamanje kwe-transmitter, idivaysi ye-semiconductor kumele ibe nephuzu elijwayelekile elisebenzayo, kanye nokunikezwa kwamandla okusebenza okujwayelekile kudinga ukuhlinzekwa ngokuhlinzekwa kwamandla, ngakho-ke isiginali yamanje kufanele ibe nephuzu le-zero bukhoma. I-International Unified Internal Signal yamanje i-4-20madc, eyakha izimo ukukhiqizwa kwama-transmitters amabili.

Isimo se-voltage for transmitter ukuze sisebenze ngokujwayelekile

Efomula:Ingabe ukukhishwa kwamandla okudluliselwa kwe-transmitter;inani eliphansi lamandla kagesi ahlinzekwa amandla;umkhawulo ophezulu wokukhishwa kwamanje, imvamisa u-20mA;inani eliphakeme lokumelana komthwalo we-transmitter;inani lokumelana nocingo oluxhumayo.

I-Transmitter ye-Wire-wire kumele inikezwe amandla ngokuhlinzekwa kwamandla okukodwa kwe-DC. Ukubizwa kwamandla okubodwa okukodwa kubhekisele ekuhlinzekeni kwamandla okunamandla ezi-zero njengendawo yokuqala, kunokuba kube namandla amahle futhi amabi anikezela ngokulinganayo ku-zero voltage. I-voltage Voltage u ye-transmitter ilingana nomehluko phakathi kwamandla kagesi anikezwa amandla kanye nokwehla kwamandla kagesi kokukhishwa kwamanje ku-RL kanye ne-Resistance R ye-wire yokuhambisa. Ukuze uqinisekise ukusebenza okujwayelekile kwe-transmitter, inani le-voltage Voltage lingashintsha kuphela ngaphakathi kwebanga elithile. Uma ukwenyuka kokubuyiselwa kwemithwalo, amandla okuphakela amandla adinga ukwandiswa; Ngaphandle kwalokho, i-Power Supply Voltage ingancishiswa; Uma amandla okunikeza amandla ancipha, ukumelana kwemithwalo kudinga ukwehliswa; Ngaphandle kwalokho, ukumelana umthwalo kungandiswa.

Amandla amancane aphumelelayo okudlulisela umsebenzi wokusebenza ngokujwayelekile

Njengoba ukunikezwa kwamandla okudluliselwa kwe-wire-wire kuncane kakhulu, futhi i-voltage kagesi kabanzi ishintsha kakhulu ngokuvela kwamanje nokulayishwa kwemithwalo, ukuguquguquka kwamandla okusebenza kwengxenye ngayinye yomugqa kushintsha kakhulu. Ngakho-ke, lapho wenza i-transmitter e-wire-wire, kuyadingeka ukusebenzisa i-amplifier ehlanganisiwe ehlanganisiwe yokusebenza bese usetha isixhumanisi sokuqina se-voltage kanye nesixhumanisi samanje sokuqina ngokusebenza okuhle.

I-Transmitter emibili ye-wire inezinzuzo eziningi, ezinganciphisa kakhulu izindleko zokufaka zedivayisi, futhi ilungele ukuvikelwa nokuvikelwa kokuqhuma. Ngakho-ke, amazwe amaningi emhlabeni njengamanje asebenzisa ama-transmitter amabili.
