Embedded industrialcontrollers paub real-time tswj thiab cov ntaub ntawv ua los ntawm real-time operating systems, ceev cov ntaub ntawv tau txais thiab ua, kev sib txuas lus real-time thiab network raws tu qauv, real-time tswj algorithms thiab logic, cov ntaub ntawv cia thiab ua. Qhov no ua rau muaj kev tswj hwm kev lag luam los teb sai sai rau cov teeb liab sab nraud thiab cov xwm txheej, thiab ua kom muaj kev tswj hwm tam sim thiab kev txiav txim siab kom tau raws li lub sijhawm tiag tiag ntawm kev tsim khoom lag luam.
Tus yuam sij kom paub txog kev tswj hwm lub sijhawm tiag tiag thiab kev ua cov ntaub ntawv ntawm cov khoom lag luam embedded yog kev sib xyaw ntawm cov khoom siv thiab software.
Cov hauv qab no yog qhov general realization:
1. Real-time operating system (RTOS): Embedded industrial computer feem ntau siv lub sijhawm ua haujlwm tiag tiag los tswj cov haujlwm thiab cov peev txheej los xyuas kom meej cov lus teb raws sijhawm thiab kev teem sijhawm ua ntej ntawm cov haujlwm, RTOS muaj qhov qis qis thiab kev kwv yees kom tau raws li qhov xav tau tiag tiag. - tswj lub sijhawm.
2 ceev teb kho vajtse: embedded industrial tswj tshuab hardware feem ntau xaiv cov processors ua tau zoo thiab tshwj xeeb kho vajtse modules los muab cov ntaub ntawv ceev ceev thiab teb muaj peev xwm. Cov khoom siv kho vajtse no yuav suav nrog cov teeb liab digital processor (DSP), moos real-time (RTC), hardware timers thiab lwm yam.
3 kev sib txuas lus hauv lub sijhawm: embedded industrial computer xav tau kev sib txuas lus nrog lwm yam khoom siv hauv lub sijhawm, xws li sensors, actuators, thiab lwm yam, feem ntau siv kev sib txuas lus interfaces yog Ethernet, CAN tsheb npav, RS485, thiab lwm yam., cov interfaces no muaj cov ntaub ntawv siab. hloov pauv tus nqi thiab kev ntseeg siab.
4, cov ntaub ntawv ua algorithm optimization: txhawm rau txhim kho kev ceev thiab kev ua haujlwm ntawm cov ntaub ntawv ua haujlwm, embedded industrial computer feem ntau yuav optimize cov ntaub ntawv ua algorithm. Qhov no suav nrog kev siv cov algorithms ua haujlwm tau zoo thiab cov qauv ntaub ntawv, txo cov meta-luam thiab kev nco siv los txhim kho kev ua haujlwm.
5, lub sijhawm teem sijhawm thiab kev tswj xyuas haujlwm: RTOS yuav ua raws li qhov tseem ceeb ntawm txoj haujlwm thiab lub sijhawm txwv, sijhawm teem sijhawm thiab kev tswj xyuas cov haujlwm, los ntawm kev faib cov haujlwm tsim nyog thiab kev teem sijhawm algorithms, embedded industrial controllers Yu txaus los xyuas kom meej tias cov real-time thiab stability ntawm cov hauj lwm tseem ceeb.
Feem ntau, embedded d-controller los ntawm kev sib xyaw ntawm cov khoom siv thiab software siv lub sijhawm ua haujlwm ntawm lub sijhawm, cov khoom siv teb ceev ceev, kev sib txuas lus hauv lub sijhawm, kev ua kom zoo dua qub thiab sijhawm teem sijhawm thiab kev tswj xyuas haujlwm kom ua tiav kev tswj xyuas thiab ua cov ntaub ntawv. kev xav tau. Qhov no ua rau D-tswj system kom tswj tau zoo thiab ruaj khov thiab ua kom cov ntaub ntawv ntawm lub sijhawm tiag tiag ntawm qhov xwm txheej loj.
