Ndeupi musiyano uripo pakati peHMI nePLC?
Zviri Mukati
- 1. HMI munhu-muchina interface:
- 2. PLC programmable logic:
- 3. PLC programmable logic inogona kushandiswa kumaindasitiri otomatiki:
- 4. HMI munhu-muchina interface inogona kushandiswa mumotokari:
- 5. Ndeupi musiyano uripo pakati peHMI nePLC:
1. HMI munhu-muchina interface:
HMI inonziwo munhu-muchina interface, inozivikanwawo se "munhu-muchina interface". Munhu-muchina interface ndiyo yepakati yekudyidzana uye kuchinjana ruzivo pakati pehurongwa nemushandisi. Mushandisi anogona kupindirana kana kudzora mudziyo. Mhando yekudyidzana inosanganisira asi haina kuganhurirwa kune oparesheni control panel, iyo zvakare inovhara iyo software interface, mhinduro meshini, nezvimwe.
HMI tekinoroji iri kuramba ichiwedzera kukura. Kubva pamabhatani echinyakare kusvika kuzvino touch screens uye virtual tekinoroji, HMI yemazuva ano inowanzoshandiswa mumaindasitiri ekudzora masisitimu, dzimba dzakangwara, mota dzemukati kudzora, zvekurapa nezvimwe minda.
2. PLC programmable logic:
PLC programmable logic inoshandiswa zvakanyanya mumaindasitiri ekudzora masisitimu ane 4U maindasitiri makomputa. Inowanzo shandiswa mumaindasitiri akangwara ekugadzira, maindasitiri otomatiki ekugadzira mitsara, maitiro ekudzora, nezvimwe. Pfungwa yayo huru ndeye kushandisa chiratidzo chekuisa uye kuburitsa kutonga zvinoenderana ne preset logic.
3. PLC programmable logic inogona kushandiswa kumaindasitiri otomatiki:
Kechipiri, PLC inogona zvakare kushandiswa kudzora kufamba, sekutamisa kwemidziyo yemuchina, iyo inowanzo ratidzwa muhuwandu hwedhijitari. Nzira inonyanya kushanda yekudzora kufamba ndeye kushandisa NC, inova tekinoroji yekudzora tekinoroji. Iyi tekinoroji yakavakirwa paAmerican komputa yekudzora tekinoroji uye ikozvino yakanyanya kunaka.
4. HMI munhu-muchina interface inogona kushandiswa mumotokari:
Iyo Human-Machine Interface (HMI) mumotokari inoita basa rakakosha mukuona kuti mutyairi anoramba aine ruzivo uye achidzora mota.
Sense of Control: HMI inopa chaiyo-nguva ruzivo nezve mamiriro emotokari, senge kumhanya, mazinga emafuta, kumanikidza matai, uye imwe data yakakosha. Izvi zvinoita kuti mutyairi azive mamiriro emotokari uye anogona kuita zvisarudzo zvine ruzivo, izvo zvinoderedza njodzi yetsaona nekuda kwekusaziva.
Feedback Mechanism: Iyo HMI sisitimu inopa mhinduro muchimiro chekuzivisa, mwenje yekuyambira, zviziviso zvezwi, kana kunyange zvinoonekwa zvinokurudzira. Semuenzaniso, kana mota ikadarika sipidhi inoganhurwa, HMI system inogona kuzivisa mutyairi, ichideredza njodzi yenjodzi dzine chekuita nekumhanya.
Kudzivirira Tsaona: HMI masisitimu anogona kusanganiswa nemasensa, makamera, uye humwe hunyanzvi hwepamberi mumotokari dzemazuvano kutarisa mamiriro chaiwo ekutyaira. Masisitimu aya anogona kupa mutyairi yambiro nezvenjodzi dzingangoitika, sedzimotokari dziri pedyo, vanofamba netsoka, kana zvipingamupinyi, zvichibatsira kudzivirira njodzi dzisati dzaitika.
5. Ndeupi musiyano uripo pakati peHMI nePLC:
Nepo zvese HMI (Human-Machine Interface) uye PLC (Programmable Logic Controller) ari zvikamu zvakakosha mumaindasitiri otomatiki, anoshanda akasiyana mabasa:
HMI (Human-Machine Interface): HMI ndiyo interface iyo vanhu vanodyidzana nayo nemichina kana masystem ekudzora. Inoratidza data uye zvimiro kubva kune sisitimu mune-mushandisi-inoshamwaridzika, yekuona fomati, inobvumira vashandisi kutarisa uye kutonga maitiro. HMIs inowanzo sanganisira touchscreens uye graphical interfaces inopa chaiyo-nguva zvigadziriso uye mhinduro. Chinangwa cheHMI chiri pakudyidzana kwevashandisi, chimiro chehurongwa, uye nyore kushanda. Industrial Panel PC inopa mhinduro huru yekugadzira HMI masisitimu.
PLC (Programmable Logic Controller): PLCs makomputa akasarudzika anoshandiswa kudzora uye otomatiki maindasitiri maitiro. Ivo vanoita pre-programmed logic yekutarisa mapimendi (senge sensors) uye kutonga zvinobuda (senge mota, mwenje, kana mavharuvhu). PLCs inobata iyo chaiyo kutonga kwemichina uye maitiro, kuita mabasa anoenderana nepfungwa uye akarongwa mirairo. Izvo zvakagadzirirwa kusimba uye kuvimbika munzvimbo dzakaoma dzeindasitiri.
Pfupiso:
- HMI ndiyo interface yekuti vashandisi vevanhu vatarise uye vabatane nehurongwa. IP65 Bata Panel PC inogona kuva yakanakira nzvimbo dzekunze dzeindasitiri.
- PLC ndiye mutongi anogadzira zvinopinda uye anoita mirairo yekudzora maindasitiri emuchina uye masisitimu.
Mune yakajairwa setup, PLC inoita iyo yekutonga logic, nepo HMI ichibvumira vashandisi kuona chimiro uye kugadzirisa sezvinodiwa. Kuti uwane mamwe mhinduro dzepamusoro dzeHMI, unogona kutarisa akasiyana marudzi emaindasitiri mapaneru maPC, akadai se 8-inch Industrial Panel PC, 10-inch Industrial Panel PC, 12-inch Industrial Panel PC, kana 15-inch Industrial Panel PC. Kune zviratidziro zvakakura, sarudzo senge 17-inch Industrial Panel PC uye 19-inch Industrial Panel PC zvingava zvakakodzera. Kana iwe uchida yakatokura skrini, funga iyo 21-inch Industrial Panel PC.
Izvi zvinosimudzira yako HMI sisitimu neakawanda akasimba uye ane scalable mhinduro dzakarongedzerwa kune chaiwo maindasitiri anodikanwa.
