Umqondo wokuklama wesisindo sezimoto ezinamakhanda amaningi ashukumisayo ngokusekelwe ku-SmaURTOS51

Umbhali: Smartweigh– Isisindo Sezinhloko Eziningi

1 Isingeniso Isisindo setroli esiguquguqukayo sisho ukuthi itroli idlula etafuleni lekhabhinethi elinobubanzi obuthile ngesilinganiso esithile. Isisindo esiphelele se-axle ngayinye yetroli silinganiswa kusukela etafuleni lekhabhinethi elinobunzima, bese isisindo esiphelele setroli siqongelelwa. Inqubo yonke yokulinganisa iyinqubo eqinile yesikhathi sangempela, futhi umklamo we-single-chip kumele uqoqe ngokushesha ulwazi lwedatha ye-axis ngayinye yetroli bese ulinganisa ngokushesha isisindo sayo esiphelele. Uma isivinini sokuklama i-single-chip sihamba kancane kakhulu noma umklamo wokuhlela ungahambisani nesayensi, kuzobangela izinkinga zokuthembeka nokuthembeka kwephaneli yezinsimbi.

Isofthiwe yeselula yezinsimbi eziningi ezisebenzayo eziningi namuhla isebenzisa uhlelo lokuklama uhlelo lwangaphambili/lwangemuva. Konke ukusebenza kohlelo kuyisistimu ye-loop engenamkhawulo. Uhlelo lwe-loop lokusebenza lwangemuva luvumela ama-culvert ahlobene ukwenza imisebenzi yangempela ehlobene, futhi luqeda izinsizakalo zesistimu ukuxazulula izehlakalo ezimbi ezinemicu eminingi. . Leyo mibono yendabuko yokuklama uhlelo inezinkinga ezinkulu. Lonke uhlelo lokusebenza luyi-chemistry yezinto eziphilayo. Kunzima ukuklama nokwandisa ukusebenza kohlelo lwesikhathi sangempela. Kunzima ukufeza ikhambi elilula nelinengqondo lezehlakalo ezimbi ngemithetho eqinile yesikhathi.

Ukufakelwa kabusha uhlelo lokusebenza olufakwe kuthuluzi lemisebenzi eminingi kungasingatha kahle izinkinga ezingenhla, futhi kwenze ukuthuthukiswa kwesofthiwe kusebenze ngendlela ejwayelekile futhi kube lula ukuyithola, kuqedele uhlelo lokuklama kwe-modular futhi kunciphise inqubekela phambili yokuthuthukiswa. Ngokwemvelo, i-RTOS ngokwayo kumele ithathe inani elithile lezinsiza. Ngokuthambekela kokuthuthukiswa kobuchwepheshe be-semiconductor, izici zezingxenye ziyaqhubeka nokukhula futhi izindleko ziyaqhubeka nokwehla, okwenza izindleko ze-RTOS zingabe zisabalulekile. Isisindo sezimoto esinamandla amaningi ukufakelwa kabusha kohlelo lokusebenza olufakwe ku-mobile, okuthuthukisa ukuthembeka nokuthembeka kwesofthiwe yohlelo kuhlelo lokusebenza oluthile.

2 Uhlelo oluphelele lwesistimu Isisindo sezimoto esine-dynamic multihead sakhiwe kakhulu yi-module yokulawula ukuqoqwa kwedatha, i-module yokulawula indlela yokucubungula idatha, i-module yokulawula ulwazi lokubonisa, i-module yokulawula ukuxhumana kwedatha, i-chip yememori yangaphandle kanye ne-watchdog yangaphandle 1, njengoba kuboniswe ku-Figure 1. I-module yokulawula ukuqoqwa kwedatha izibophezela ukukhulisa nokuhlunga isignali yedatha yesisindo se-net etholwe yi-wearing sensor, iyiguqule ibe yisignali ye-analog bese iyidlulisela ku-CPU; i-CPU izibophezela ukuxhumana nedivayisi ngayinye yangaphandle kanye nokuhlaziywa kanye nesixazululo sesignali yedatha yesisindo se-net, futhi izoxazulula inkinga. Isignali yedatha yesisindo se-net eqediwe ithunyelwa ku-module yokulawula ulwazi lokubonisa kanye ne-module yokulawula ukuxhumana; i-module yokulawula ulwazi lokubonisa inesibopho solwazi lokubonisa lwesignali yedatha yesisindo se-net: i-module yokulawula ukuxhumana inesibopho sokuthumela isignali yedatha yesisindo se-net kwisofthiwe yekhompyutha yokusingatha; i-chip yememori yangaphandle igcinwa ku-instrument panel. Amapharamitha amakhulu: Izinkinobho zomsebenzi zisetshenziselwa ukusetha nokushintsha amapharamitha ayinhloko e-instrument panel; i-watchdog yangaphandle 1 isetshenziselwa ukuthuthukisa ukuphikiswa kwe-instrument panel nokuthuthukisa ukuthembeka kwe-instrument panel. 3 Izimiso Zesekethe Yokucushwa Kwehadiwe 3.1 Imojuli Yokulawula Ukuqoqwa Kwedatha Ngenxa yokuthi ithebula lokulinganisa amakhanda amaningi kumele libe nokunemba okuphezulu, kukhethwa i-converter yangaphandle ye-A/D bese kusetshenziswa i-CS5532.

Le ngxenye iyi-analog/digital converter enamashaneli amaningi enomsindo ophansi kakhulu okhishwa yi-British CirrusLogic, ngoba isebenzisa ubuchwepheshe bebhalansi yokushaja kanye ne-chopper yohlelo lokulawula inzuzo yomsindo ophansi kakhulu, i-amplifier yokulinganisa ezinzile nenembile, Ukuhlanganiswa kwangaphakathi kwemisebenzi yokukhulisa kanye nokuhlunga kungafeza imiphumela yokukhipha yamaphikseli angu-24-bit, futhi kunezinzuzo zobubanzi obuphezulu obuguquguqukayo kanye nezinketho zokunikezwa kwamandla okushintsha okuguquguqukayo, okwenza le ngxenye ifaneleke kakhulu ekulinganisweni okuguquguqukayo. I-voltage yayo yokusebenza ejwayelekile ikhiqizwa yi-component ye-voltage yokusebenza ejwayelekile yobungcweti i-AD780. Isekethe yamandla iboniswe kuMfanekiso 2.

3.2 Ama-Microcontroller nama-memory chip angaphandle Ama-Microcontroller ayisihluthulelo sesofthiwe yesistimu, futhi izinzuzo nezingozi zezici zawo zinquma ngokushesha ukunemba kwemishini yokukala.
