Mafakitale ophatikizidwaolamulira amazindikira nthawi yeniyeni yolamulira ndi kukonza deta kudzera mu machitidwe ogwiritsira ntchito nthawi yeniyeni, kupeza deta mofulumira ndi kukonza, kuyankhulana kwa nthawi yeniyeni ndi ma protocol a intaneti, ma algorithms a nthawi yeniyeni ndi malingaliro, kusunga deta ndi kukonza. Izi zimathandiza kuti kayendetsedwe ka mafakitale azitha kuyankha mwamsanga zizindikiro ndi zochitika zakunja, ndikuwongolera mwamsanga ndi kupanga zisankho kuti zikwaniritse zofunikira zenizeni za mafakitale.
Chinsinsi cha kuzindikira nthawi yeniyeni yolamulira ndi kukonza deta ya olamulira ophatikizidwa ndi mafakitale ndi kuphatikiza kwa hardware ndi mapulogalamu.
Zotsatirazi ndikuzindikira konse:
1. Makina ogwiritsira ntchito nthawi yeniyeni (RTOS): Makompyuta ophatikizidwa a mafakitale nthawi zambiri amagwiritsa ntchito nthawi yeniyeni yoyendetsera ntchito kuti athetse ntchito ndi zothandizira kuti atsimikizire kuyankha kwanthawi yake komanso kukonzekera kwapadera kwa ntchito, RTOS ili ndi latency yochepa komanso yodziwiratu kuti ikwaniritse zosowa zenizeni. -kuwongolera nthawi.
2 zida zoyankha mwachangu: zida zamakina ophatikizidwa ndi mafakitale nthawi zambiri zimasankha mapurosesa ochita bwino kwambiri ndi ma module apadera a hardware kuti apereke kusinthika kwa data mwachangu ndikuyankha. Ma module a hardwarewa angaphatikizepo purosesa ya digito (DSP), wotchi yeniyeni yeniyeni (RTC), zowerengera za hardware ndi zina zotero.
3 mawonekedwe a nthawi yeniyeni yolumikizirana: makompyuta ophatikizidwa ndi mafakitale amafunikira kulumikizana ndi zida zina munthawi yeniyeni, monga masensa, ma actuators, ndi zina zambiri, njira zolumikizirana zomwe zimagwiritsidwa ntchito nthawi zambiri ndi Ethernet, CAN bus, RS485, ndi zina zambiri. kusamutsa mlingo ndi kudalirika.
4, data processing aligorivimu kukhathamiritsa: kuti patsogolo liwiro ndi dzuwa processing deta, ophatikizidwa mafakitale kompyuta zambiri konza aligorivimu deta processing. Izi zikuphatikiza kugwiritsa ntchito ma aligorivimu aluso ndi mapangidwe a data, kuchepetsa kuwerengera kwa meta ndi kukumbukira kukumbukira kuti makina azigwira bwino ntchito.
5, kukonza nthawi yeniyeni ndi kasamalidwe ka ntchito: RTOS idzakhazikitsidwa ndi ntchito yofunikira ndi zovuta za nthawi, kukonzekera nthawi yeniyeni ndi kasamalidwe ka ntchito, kupyolera mu kugawa bwino ntchito ndi ndondomeko zoyendetsera ntchito, olamulira mafakitale ophatikizidwa ndi Yu mokwanira kuti atsimikizire kuti nthawi yeniyeni ndi kukhazikika kwa ntchito zofunika kwambiri.
Kawirikawiri, d-controller yophatikizidwa kupyolera mukuphatikizira kwa hardware ndi mapulogalamu pogwiritsa ntchito makina ogwiritsira ntchito nthawi yeniyeni, zida zoyankhira mofulumira, nthawi yeniyeni yolumikizirana, kukhathamiritsa kukhathamiritsa ndi kukonza nthawi yeniyeni ndi kasamalidwe ka ntchito kuti akwaniritse nthawi yeniyeni yolamulira ndi kukonza deta. zofunika. Izi zimathandiza kuti dongosolo la D-control lizitha kulamulira bwino komanso mosasunthika ndikutulutsa deta yeniyeni ya zochitika zazikulu.
