Maitiro mana makuru mukuvandudza kweDCS control system tekinoroji mune ramangwana
2023-12-08
DCS system yakakura otomatiki control system kunze kwePLC. Inoshandiswa zvakanyanya muindasitiri yemakemikari, simba rekupisa uye mamwe minda. Nekudaro, kudiwa kweotomatiki tekinoroji mukugadzira kwakawedzera kuvandudzwa. Iyo yechinyakare DCS sisitimu haichakwanisa kuzadzisa zvinodiwa uye inoda kuvandudzwa. Iyo DCS system ndeye otomatiki yekudzora sisitimu inoshandisa makomputa akawanda kudzora akawanda kudzora zvishwe mukugadzira, uye panguva imwe chete inogona nepakati kuwana data, kutonga nepakati uye nepakati kutonga. Iyo yakagoverwa yekudzora sisitimu inoshandisa microprocessors kudzora dunhu rega rega zvakasiyana, uye inoshandisa madiki uye epakati-saizi maindasitiri ekudzora makomputa kana yakakwira-performance microprocessors kuita iyo yepamusoro nhanho kutonga. Mushure mekushandisa kuenderera mberi kwemakore, zvimwe zvipimo zvekuvandudzwa kweDCS system muindasitiri zvinoratidzwa zvishoma nezvishoma. Matambudziko eDCS ndeaya anotevera: (1) 1 kusvika ku1 chimiro. Chimbo chimwe, peya yemitsara yekutapurirana, inoendesa chiratidzo chimwe munzira imwe. Ichi chimiro chinotungamira kune yakaoma wiring, nguva refu yekuvaka, yakakwirira yekuisa mutengo uye yakaoma kugadzirisa. (2) Kusavimbika zvakanaka. Analog chiratidzo chekufambisa hachina kuderera chete mukurongeka, asiwo panjodzi yekukanganiswa. Nokudaro, matanho akasiyana-siyana anotorwa kuti avandudze kupesana-kupindira uye kutapurirana kwechokwadi, uye mhedzisiro inowedzera mari. (3) Kusadzoreka. Mukamuri yekudzora, mutyairi haakwanise kunzwisisa mamiriro ekushanda echiridzwa cheanalog yemunda, kana kugadzirisa marongero ayo, kana kufanotaura njodzi, zvichikonzera kuti mushandisi ashaye simba. Hazvishamisi kuti vashandisi vawane kukanganisa kwechiridzwa chemunda munguva. (4) Kusashanda zvakanaka. Kunyangwe zviridzwa zveanalogi zvakabatanidza iyo 4 ~ 20mA chiratidzo chiyero, mazhinji ehunyanzvi paramita achiri akatemerwa nemugadziri, izvo zvinoita kuti zviridzwa zvemhando dzakasiyana zvisagone kuchinjana. Nekuda kweizvozvo, vashandisi vanovimba nevagadziri, vasingakwanise kushandisa zviridzwa zvinofananidzwa neakanakisa kuita uye mutengo reshiyo, uye kunyangwe mamiriro ekuti vagadziri vega vanotonga musika. nzira yebudiriro Kuvandudzwa kweDCS kwave kwakasimba uye kunoshanda. Hapana mubvunzo kuti ichiri chikuru chekushandiswa uye kusarudzwa kwemaindasitiri otomatiki masisitimu parizvino. Izvo hazvizobve kubva padanho remunda process control nekubuda kwefieldbus tekinoroji. Nekutarisana nezvipingamupinyi, DCS icharamba ichikura nenzira dzinotevera: (1) Kusimukira kwakanangana negwara rakazara: kuvandudzwa kweakamisikidzwa dhata yekutaurirana malink uye network yekukurukurirana ichaumba yakakura sisitimu yezvigadzirwa zvemaindasitiri senge akasiyana ega (akawanda) loop regulators, PLC, maindasitiri PC, NC, nezvimwe kuzadzisa zvinodiwa. yefekitari otomatiki uye chinja kune yakajairika maitiro ekuvhurika. (2) Kubudirira kune hungwaru: kusimudzira dhatabhesi system, kufunga basa, nezvimwewo, kunyanya kushandiswa kweruzivo base system (KBS) uye nyanzvi system (ES), senge kuzvidzidzira kuzvitonga, kuremerwa kuongororwa, kuzvigadzirisa, nezvimwewo, AI ichaonekwa pamatanho ese eDCS. Zvakafanana neFF fieldbus, microprocessor-based intelligent madivayiri akadai seakangwara I/O, PID controller, sensor, transmitter, actuator, human-machine interface, uye PLC zvabuda imwe mushure meimwe. (3) DCS industrial PC: Yave tsika huru kuumba DCS ne IPC. PC yave yakajairika chiteshi chiteshi kana node muchina weDCS. PC-PLC, PC-STD, PC-NC, nezvimwewo ndivo mapiyona ePC-DCS. IPC yave chikuva chehardware cheDCS. (4) DCS nyanzvi: Kuti iite kuti DCS inyatsokodzera chikumbiro munzvimbo dzakasiyana siyana, zvinodikanwa kuti uwedzere kunzwisisa maitiro uye mashandisirwo ezvinodiwa zvezviyero zvinoenderana, kuitira kuti zvishoma nezvishoma zviumbe senge nyukliya simba DCS, substation DCS, girazi. DCS, simende DCS, nezvimwewo.
