Momwe mungatsimikizire kudalirika kwa chowongolera - Mau oyamba a nsanja yoyeserera ya hardware-in-the-loop (HIL)-2

02 Kodi ubwino wa nsanja ya HIL ndi wotani?

Popeza kuyesa kungachitike pa magalimoto enieni, bwanji kugwiritsa ntchito nsanja ya HIL poyesa?

Kusunga ndalama:
Kugwiritsa ntchito nsanja ya HIL kungachepetse nthawi, mphamvu za anthu, ndi ndalama. Kuchita mayeso m'misewu ya anthu onse kapena m'misewu yotsekedwa nthawi zambiri kumafuna ndalama zambiri. Nthawi ndi ndalama zomwe zimagwiritsidwa ntchito pokonza kapena kukonza zida ndi mapulogalamu pamagalimoto oyesera siziyenera kunyalanyazidwa. Kuyesa magalimoto enieni kumafuna akatswiri angapo (osonkhanitsa, oyendetsa, mainjiniya amagetsi, ndi zina zotero) kuti akhale odikira kuti athetse mavuto aliwonse omwe angabuke panthawi yoyesa. Ndi kuyesa nsanja ya HIL, zambiri zomwe zili muyeso zimatha kumalizidwa mu labotale, ndipo mawonekedwe a ogwiritsa ntchito a nsanja ya HIL amalola kusintha nthawi yeniyeni magawo osiyanasiyana a chinthu cholamulidwa popanda kufunikira kusokoneza magalimoto ndi ntchito yokonzanso.

Kuchepetsa zoopsa:
Pa nthawi yotsimikizira galimoto yeniyeni, pamakhala zoopsa za ngozi za pamsewu, kugwedezeka kwa magetsi, ndi kulephera kwa makina potsimikizira zinthu zoopsa komanso zoopsa. Kugwiritsa ntchito nsanja ya HIL pamayeso awa kungateteze bwino antchito ndi katundu, kuthandizira kuyesa kwathunthu kukhazikika kwa makina ndi chitetezo m'mikhalidwe yovuta kwambiri, ndikuwonetsa zabwino zomveka pakupanga kapena kukweza owongolera.

Kukula kogwirizana:
Pakukonza pulojekiti yatsopano, chowongolera ndi chinthu cholamulidwa nthawi zambiri zimapangidwa nthawi imodzi. Komabe, ngati palibe chinthu cholamulidwa chomwe chilipo, kuyesa kwa chowongolera kungayambe kokha pambuyo poti chinthu cholamulidwa chatha. Ngati nsanja ya HIL ilipo, imatha kutsanzira chinthu cholamulidwa, zomwe zimathandiza kuti kuyesa kwa chowongolera kupitirire.

Kusamalira zolakwika zenizeni:
Pa nthawi yoyesera galimoto yeniyeni, nthawi zambiri zimakhala zovuta kubwereza zolakwika zina monga kuwonongeka kwa hardware kapena ma short circuits, ndipo pakhoza kukhala zoopsa zina. Pogwiritsa ntchito mawonekedwe ogwirira ntchito a nsanja ya HIL, zolakwika za munthu payekha kapena zingapo zitha kubwerezedwanso, zomwe zimathandiza kuyesa bwino momwe wowongolerayo amagwirira ntchito mitundu yosiyanasiyana ya zolakwika.

03 Kodi mungatani kuti muyesere HIL platform?

Kukhazikitsa nsanja:
Kukhazikitsa nsanja kumaphatikizapo kukhazikitsa mapulogalamu ndi ma hardware platforms onse. Pa kuyesa magalimoto, nsanja ya mapulogalamu imaphatikizapo kupanga ma test scenario models, ma simulation models a masensa, ndi ma dynamics models a magalimoto, komanso mapulogalamu oyang'anira mayeso. Kukhazikitsa nsanja ya hardware kumafuna makabati oyeserera nthawi yeniyeni, ma I/O interface boards, ma sensa simulators, ndi zina zotero. Kusankha zigawo za nsanja ya hardware kumadalira kwambiri kusankha msika, chifukwa kudzikuza kungakhale kovuta.

Kuphatikiza kwa HIL:
Sankhani zida zoyenera zoyesera malinga ndi zofunikira ndikupanga malo oyenera oyesera. Kenako phatikizani mitundu ya algorithm yomwe ikugwira nawo ntchito ndi malo oyesera kuti mupange dongosolo lotsekedwa. Komabe, pali zida zosiyanasiyana zoyesera zomwe zikupezeka pamsika, kuchokera kwa opanga osiyanasiyana, okhala ndi miyezo yosiyanasiyana ndi deta yolumikizirana poyerekeza ndi wowongolera yemwe akuyesedwa, zomwe zimapangitsa kuti kuphatikizana kukhale kovuta pang'ono.

Zochitika zoyesera:
Zochitika zoyesera ziyenera kuphimba zochitika zambiri zogwiritsidwa ntchito komanso kuganiziranso za mikhalidwe yosabwerezedwanso. Zizindikiro za masensa ziyenera kugwirizana ndi zochitika zenizeni. Kulondola ndi kukwanira kwa mayeso ndi zizindikiro zofunika kwambiri za kugwira ntchito kwa mayeso a HIL.

Chidule cha mayeso:
Chidule cha mayeso chiyenera kuphatikizapo: 1. Malo oyeserera, nthawi yoyesera, zomwe zili mu mayeso, ndi ogwira ntchito omwe akukhudzidwa; 2. Ziwerengero ndi kusanthula mavuto omwe akumana nawo panthawi yoyesa, chidule cha mavuto omwe sanathetsedwe; 3. Malipoti a mayeso ndi kutumiza zotsatira. Kuyesa kwa HIL nthawi zambiri kumachitika kokha, kumafuna kumalizidwa kwa kasinthidwe ndikudikirira kuti mayeso athe, zomwe zimathandiza kukonza magwiridwe antchito a mayeso ndikuwonetsetsa kuti mayesowo ndi ofanana.
