Kodi pali kusiyana kotani pakati pa HMI ndi PLC?
M'ndandanda wazopezekamo
- 1. HMI mawonekedwe amunthu-makina:
- 2. PLC yokonzekera logic:
- 3. PLC logicable logic angagwiritsidwe ntchito mafakitale automation:
- 4. HMI anthu-makina mawonekedwe angagwiritsidwe ntchito magalimoto:
- 5. Kodi pali kusiyana kotani pakati pa HMI ndi PLC:
1. HMI mawonekedwe amunthu-makina:
HMI imatchedwanso mawonekedwe a makina amunthu, omwe amadziwikanso kuti "mawonekedwe a makina amunthu". Mawonekedwe a makina a anthu ndiye njira yolumikizirana komanso kusinthanitsa zidziwitso pakati pa makina ndi ogwiritsa ntchito. Wogwiritsa ntchito amatha kulumikizana kapena kuwongolera chipangizocho. Mtundu wolumikizirana umaphatikizapo koma osangokhala pagawo loyang'anira ntchito, lomwe limakhudzanso mawonekedwe apulogalamu, makina oyankha, ndi zina zambiri.
Tekinoloje ya HMI ikukula kwambiri. Kuchokera pa mabatani achikhalidwe kupita ku zowonetsera zamakono zamakono ndi zamakono zamakono, HMI yamakono imagwiritsidwa ntchito nthawi zambiri m'makina olamulira mafakitale, nyumba zanzeru, kayendetsedwe ka mkati mwa magalimoto, zipangizo zamankhwala ndi zina.
2. PLC yokonzekera logic:
logic yosinthika ya PLC imagwiritsidwa ntchito mwapadera pamakina owongolera mafakitale okhala ndi makompyuta amakampani a 4U. Nthawi zambiri amagwiritsidwa ntchito m'mafakitale opangira zinthu mwanzeru, mizere yopangira makina opanga makina, kuwongolera njira, ndi zina zambiri. Mfundo yake yayikulu ndikugwiritsa ntchito ma signature athandizira ndikuwongolera molingana ndi malingaliro okhazikitsidwa.
3. PLC logicable logic angagwiritsidwe ntchito mafakitale automation:
Kachiwiri, PLC itha kugwiritsidwanso ntchito powongolera zoyenda, monga kusuntha kwa zida zamakina, zomwe nthawi zambiri zimawonetsedwa kuchuluka kwa digito. Njira yothandiza kwambiri yowongolera kuyenda ndi kugwiritsa ntchito NC, yomwe ndiukadaulo wowongolera digito. Ukadaulowu umachokera kuukadaulo waku America wowongolera makompyuta ndipo tsopano ndi wangwiro kwambiri.
4. HMI anthu-makina mawonekedwe angagwiritsidwe ntchito magalimoto:
Human-Machine Interface (HMI) m'magalimoto imagwira ntchito yofunika kwambiri powonetsetsa kuti dalaivala amakhalabe odziwa komanso kuyendetsa galimoto.
Kuwongolera: HMI imapereka zidziwitso zenizeni zenizeni za momwe galimoto ilili, monga kuthamanga, kuchuluka kwamafuta, kuthamanga kwa matayala, ndi data ina yovuta. Izi zimatsimikizira kuti dalaivala akudziwa momwe galimotoyo ilili ndipo amatha kupanga zisankho zodziwika bwino, zomwe zimachepetsa chiopsezo cha ngozi chifukwa cha kusowa chidziwitso.
Ndemanga Njira: Dongosolo la HMI limapereka mayankho ngati zidziwitso, magetsi ochenjeza, zidziwitso zamawu, kapenanso zowonera. Mwachitsanzo, ngati galimoto yadutsa malire a liwiro, makina a HMI amatha kudziwitsa dalaivala, kuchepetsa ngozi zobwera chifukwa cha kuthamanga.
Kupewa Ngozi: Makina a HMI amatha kuphatikizidwa ndi masensa, makamera, ndi matekinoloje ena apamwamba m'magalimoto amakono kuti aziwunika momwe magalimoto amayendera. Makinawa amatha kuchenjeza oyendetsa za ngozi zomwe zingachitike, monga magalimoto apafupi, oyenda pansi, kapena zopinga, zomwe zimathandiza kupewa ngozi zisanachitike.
5. Kodi pali kusiyana kotani pakati pa HMI ndi PLC:
Ngakhale onse a HMI (Human-Machine Interface) ndi PLC (Programmable Logic Controller) ali zigawo zofunika pakupanga makina, amagwira ntchito zosiyanasiyana:
HMI (Human-Machine Interface): HMI ndi mawonekedwe omwe anthu amalumikizana ndi makina kapena machitidwe owongolera. Imawonetsa zidziwitso ndi ziwerengero kuchokera kudongosolo mu mawonekedwe osavuta kugwiritsa ntchito, owoneka bwino, omwe amalola ogwiritsa ntchito kuyang'anira ndikuwongolera njira. Ma HMI nthawi zambiri amakhala ndi ma touchscreens ndi ma graphical interfaces omwe amapereka zosintha zenizeni komanso mayankho. Cholinga cha HMI ndikulumikizana kwa ogwiritsa ntchito, mawonekedwe adongosolo, komanso kumasuka kwa ntchito. Industrial Panel PC imapereka yankho lalikulu popanga machitidwe a HMI.
PLC (Programmable Logic Controller): Ma PLC ndi makompyuta apadera omwe amagwiritsidwa ntchito kuwongolera ndikuwongolera njira zama mafakitale. Amapanga malingaliro okonzedweratu kuti ayang'anire zolowa (monga masensa) ndikuwongolera zotuluka (monga ma mota, magetsi, kapena ma valve). Ma PLC amayang'anira kuwongolera kwenikweni kwa makina ndi njira, kuchita ntchito motengera malingaliro ndi malangizo okonzedwa. Zapangidwa kuti zikhale zolimba komanso zodalirika m'malo ovuta a mafakitale.
Chidule:
- HMI ndi mawonekedwe ogwiritsira ntchito anthu kuti aziyang'anira ndi kuyanjana ndi dongosolo. IP65 Touch Panel PC akhoza kukhala abwino kwa mapangidwe akunja mafakitale.
- PLC ndiye woyang'anira yemwe amakonza zolowetsa ndikuchita malamulo kuti aziwongolera makina ndi machitidwe a mafakitale.
Pamakhazikitsidwe wamba, PLC imachita zowongolera, pomwe HMI imalola ogwiritsa ntchito kuwona momwe alili ndikusintha momwe angafunikire. Pamayankho apamwamba kwambiri a HMI, mutha kuyang'ana mitundu yosiyanasiyana yama PC apagulu la mafakitale, monga ma 8-inch Industrial Panel PC, 10-inch Industrial Panel PC, 12-inch Industrial Panel PC, kapena 15-inch Industrial Panel PC. Kwa mawonedwe akuluakulu, zosankha monga 17-inch Industrial Panel PC ndi 19-inch Industrial Panel PC zingakhale zoyenera. Ngati mukufuna chophimba chachikulu, ganizirani za 21-inch Industrial Panel PC.
Izi zidzakulitsa dongosolo lanu la HMI ndi mayankho amphamvu komanso owopsa omwe amapangidwira zosowa zamakampani.
