Iindlela ezine eziphambili kuphuhliso lwethekhnoloji yenkqubo yolawulo ye-DCS kwixesha elizayo
2023-12-08
Inkqubo ye-DCS yinkqubo enkulu yolawulo oluzenzekelayo ngaphandle kwe-PLC. Isetyenziswa kakhulu kwishishini lemichiza, amandla obushushu kunye nezinye iindawo. Nangona kunjalo, imfuno yetekhnoloji ye-automation kwimveliso iye yaphuculwa ngakumbi. Inkqubo yemveli ye-DCS ayinakukwazi ukuhlangabezana neemfuno kwaye ifuna ukuphuculwa. Inkqubo ye-DCS yinkqubo yokulawula ngokuzenzekelayo esebenzisa iikhomputha ezininzi ukulawula iilophu ezininzi zokulawula kwinkqubo yokuvelisa, kwaye kwangaxeshanye inokufumana idatha ephakathi, ilawule phakathi kunye nolawulo oluphakathi. Inkqubo yokulawula esasazwayo isebenzisa i-microprocessors ukulawula isiphaluka ngasinye ngokwahlukileyo, kwaye isebenzisa iikhomputha zokulawula i-industrial encinci kunye nephakathi okanye i-microprocessors ephezulu yokusebenza ukuphumeza ulawulo oluphezulu. Emva kokusetyenziswa rhoqo kwiminyaka, ezinye izithintelo zophuhliso lwenkqubo ye-DCS kushishino zibonakaliswa ngokuthe ngcembe. Iingxaki ze-DCS zezi zilandelayo: (1) I-1 ukuya kwi-1 isakhiwo. Isixhobo esinye, iperi enye yemigca yothumelo, ihambisa isiginali enye kwicala elinye. Esi sakhiwo sikhokelela kucingo olunzima, ixesha elide lokwakha, ixabiso eliphezulu lofakelo kunye nokugcinwa okunzima. (2) Ukuthembeka kakubi. Ukuhanjiswa kwesignali ye-analog akukona nje ukuchaneka okuphantsi, kodwa kusengozini yokuphazamiseka. Ngoko ke, amanyathelo ahlukeneyo athatyathwa ukuphucula ukuchaneka kokuphazamiseka kunye nokuchaneka kokudluliselwa, kwaye umphumo wokunyusa iindleko. (3) Ngaphandle kolawulo. Kwigumbi lokulawula, umqhubi akanako ukuqonda imeko yokusebenza yesixhobo se-analog yentsimi, okanye ulungelelanise iiparitha zayo, okanye uqikelele ingozi, okubangela ukuba umqhubi angabikho kulawulo. Akuqhelekanga ukuba abaqhubi bafumane iimpazamo zesixhobo sentsimi ngexesha. (4) Ukusebenzisana kakubi. Nangona izixhobo ze-analog zidibanise umgangatho wesignali ye-4 ~ 20mA, ezininzi iiparitha zobugcisa zisachongwa ngumenzi, okwenza izixhobo zeempawu ezahlukeneyo azikwazi ukutshintshwa. Ngenxa yoko, abasebenzisi bathembele kubavelisi, abakwazi ukusebenzisa izixhobo ezihambelanayo kunye nokusebenza kakuhle kunye nomlinganiselo wexabiso, kunye nemeko yokuba abavelisi ngabanye balawula imarike. isikhokelo sophuhliso Uphuhliso lwe-DCS lukhulile kwaye luyasebenza. Akukho mathandabuzo ukuba iseyeyona nto iphambili ekusetyenzisweni nasekukhethweni kweenkqubo ezizisebenzelayo zoshishino okwangoku. Ayiyi kuhoxiswa ngokukhawuleza kwinqanaba lolawulo lwenkqubo yentsimi kunye nokuvela kobuchwepheshe be-fieldbus. Ukujongana nemiceli mngeni, i-DCS iya kuqhubeka nokuphuhliswa ngolu hlobo lulandelayo: (1) Uphuhliso olusingise kwicala elibanzi: uphuhliso lwamakhonkco onxibelelwano lwedatha asemgangathweni kunye nothungelwano lonxibelelwano luya kwenza inkqubo enkulu yezixhobo zolawulo lwamashishini ezifana nezahlukeneyo (ezininzi) zabalawuli be-loop, i-PLC, i-PC yoshishino, i-NC, njl. ye-automation yefektri kunye nokuziqhelanisa nesiqhelo sokuvuleka. (2) Uphuhliso olubhekiselele kubukrelekrele: uphuhliso lwenkqubo yesiseko sedatha, umsebenzi wokuqiqa, njl., ngakumbi ukusetyenziswa kwenkqubo yesiseko solwazi (KBS) kunye nenkqubo yeengcali (ES), njengokulawula ukuzifundela, ukuxilongwa okude, ukuzisebenzela, njl., i-AI iya kuphunyezwa kuwo onke amanqanaba e-DCS. Ngokufana ne-FF fieldbus, izixhobo ezihlakaniphile ezisekelwe kwi-microprocessor-based ezifana ne-I / O ehlakaniphile, isilawuli se-PID, inzwa, i-transmitter, i-actuator, i-interface yomshini womntu, kunye ne-PLC ziye zavela emva kwenye. (3) I-PCS yoshishino lwe-DCS: Kuye kwaba yinto ephambili yokwenza i-DCS yi-IPC. I-PC ibe sisikhululo sokusebenza esiqhelekileyo okanye umatshini we-node we-DCS. I-PC-PLC, i-PC-STD, i-PC-NC, njl. ngoovulindlela be-PC-DCS. IPC iye yaba liqonga lezixhobo ze-DCS. (4) Ubungcali be-DCS: Ukuze kwenziwe i-DCS ifaneleke ngakumbi kwisicelo kwiinkalo ezahlukeneyo, kuyimfuneko ukuqonda ngakumbi inkqubo kunye neemfuno zesicelo zezifundo ezihambelanayo, ukuze zenze ngokuthe ngcembe ezifana namandla enyukliya i-DCS, i-DCS, iglasi. I-DCS, i-DCS yesamente, njl.
