1 Kev Taw Qhia Kev ntsuas qhov hnyav ntawm lub trolley txhais tau tias lub trolley hla dhau lub rooj ntsuas qhov hnyav nrog qhov dav tag nrho ntawm qhov nrawm. Qhov hnyav tag nrho ntawm txhua lub qag ntawm lub trolley yog ntsuas los ntawm lub rooj ntsuas qhov hnyav, thiab tom qab ntawd qhov hnyav tag nrho ntawm lub trolley raug sau. Tag nrho cov txheej txheem ntsuas qhov hnyav yog ib qho txheej txheem muaj zog tiag tiag, thiab tus qauv tsim ib-chip yuav tsum sau cov ntaub ntawv ntawm txhua lub axis ntawm lub trolley tam sim ntawd thiab ntsuas nws qhov hnyav tag nrho sai sai. Yog tias qhov ceev tsim ib-chip qeeb dhau lossis tus qauv tsim programming tsis muaj kev tshawb fawb, nws yuav ua rau muaj teeb meem ntawm kev ntseeg siab thiab kev ntseeg siab rau lub vaj huam sib luag ntsuas.

Cov software xov tooj ntawm tes ntawm ntau yam twj paj nruag ntau yam niaj hnub no siv cov qauv tsim pem hauv ntej / keeb kwm yav dhau los. Txhua qhov kev ua haujlwm ntawm qhov kev pab cuam yog ib qho kev voj voog tsis kawg. Lub kaw lus ua haujlwm tom qab ua rau cov kwj deg sib piv ua haujlwm tiag tiag, thiab xaus cov kev pabcuam system los daws cov xwm txheej phem ntau-threaded. . Cov tswv yim tsim qauv programming ib txwm muaj qhov tsis zoo. Tag nrho cov kev ua haujlwm ntawm qhov kev pab cuam yog tag nrho ntawm cov tshuaj lom neeg organic. Nws nyuaj rau tsim thiab nthuav dav cov haujlwm ntawm qhov kev pab cuam tiag tiag. Nws nyuaj rau ua tiav qhov kev daws teeb meem yooj yim thiab tsim nyog rau cov xwm txheej phem nrog cov cai tswj hwm lub sijhawm nruj. siv.

Kev hloov lub embedded operating system rau hauv lub multi-function instrument tuaj yeem daws cov teeb meem saum toj no tau zoo, thiab ua rau software development ua haujlwm ntau dua thiab yooj yim nrhiav tau, ua tiav qhov programming ntawm modular design thiab txo qhov kev nce qib ntawm kev loj hlob. Ntawm chav kawm, RTOS nws tus kheej yuav tsum siv qee yam khoom siv. Nrog rau kev txhim kho ntawm semiconductor technology, cov yam ntxwv ntawm cov khoom txuas ntxiv mus nce thiab tus nqi txuas ntxiv mus txo qis, uas ua rau tus nqi ntawm RTOS tsis tseem ceeb lawm. Lub automotive dynamic multihead weigher yog kev hloov ntawm embedded operating system, uas txhim kho qhov kev ntseeg siab thiab kev ntseeg siab ntawm lub system software hauv daim ntawv thov tshwj xeeb.

2 Lub cev ntawm lub kaw lus Lub tshuab ntsuas qhov hnyav ntau lub taub hau ntawm lub tsheb feem ntau yog tsim los ntawm cov khoom siv tswj kev sau cov ntaub ntawv, cov khoom siv tswj kev ua cov ntaub ntawv, cov khoom siv tswj cov ntaub ntawv tso saib, cov khoom siv tswj kev sib txuas lus cov ntaub ntawv, lub cim xeeb sab nraud thiab lub cuab yeej saib xyuas sab nraud 1, raws li pom hauv Daim Duab 1. Cov khoom siv tswj kev sau cov ntaub ntawv ua kom loj dua thiab lim cov ntaub ntawv qhov hnyav ntawm lub ntsuas ntsuas uas pom los ntawm lub ntsuas qhov hnyav, hloov nws mus rau hauv cov teeb liab analog thiab xa mus rau CPU; CPU ua kev sib txuas lus nrog txhua lub cuab yeej sab nraud thiab kev tshuaj xyuas thiab kev daws teeb meem ntawm cov ntaub ntawv qhov hnyav ntawm lub cuab yeej, thiab yuav daws qhov teeb meem Cov ntaub ntawv qhov hnyav ntawm lub cuab yeej tiav lawm raug xa mus rau cov khoom siv tswj cov ntaub ntawv tso saib thiab cov khoom siv tswj kev sib txuas lus; cov khoom siv tswj cov ntaub ntawv tso saib yog lub luag haujlwm rau cov ntaub ntawv tso saib ntawm cov ntaub ntawv qhov hnyav ntawm lub cuab yeej: cov khoom siv tswj kev sib txuas lus yog lub luag haujlwm rau kev xa cov ntaub ntawv qhov hnyav ntawm lub cuab yeej mus rau lub khoos phis tawj software; lub cim xeeb sab nraud khaws cia rau hauv lub vaj huam sib luag ntsuas. Cov yam ntxwv tseem ceeb: Cov yuam sij ua haujlwm yog siv los teeb tsa thiab hloov cov yam ntxwv tseem ceeb ntawm lub vaj huam sib luag ntsuas; lub cuab yeej saib xyuas sab nraud 1 yog siv los txhim kho kev cuam tshuam ntawm lub vaj huam sib luag ntsuas thiab txhim kho kev ntseeg siab ntawm lub vaj huam sib luag ntsuas. 3 Cov Ntsiab Cai ntawm Kev Teeb tsa Kho Vaj Tse 3.1 Cov Qauv Tswj Xyuas Kev Sau Cov Ntaub Ntawv Vim tias lub rooj sib tw ntau lub taub hau yuav tsum muaj qhov tseeb siab, lub hloov pauv A / D sab nraud raug xaiv thiab CS5532 siv.

Cov khoom no yog lub tshuab hloov pauv analog / digital ntau txoj hauv kev nrog lub suab qis heev uas tso tawm los ntawm British CirrusLogic, vim nws siv cov thev naus laus zis sib npaug thiab lub tshuab tswj hwm qhov kev pab cuam suab qis heev, lub tshuab ntsuas ruaj khov thiab raug, kev sib koom ua ke ntawm kev nthuav dav thiab cov haujlwm lim dej tuaj yeem ua tiav 24-ntsis pixel tso zis, thiab muaj qhov zoo ntawm ntau yam dynamic thiab cov kev xaiv hloov pauv fais fab, ua rau cov khoom no tshwj xeeb tshaj yog rau kev hnyav dynamic. Nws lub zog ua haujlwm tus qauv yog tsim los ntawm cov khoom siv hluav taws xob ua haujlwm tus qauv AD780. Lub voj voog fais fab tau pom hauv Daim Duab 2.

3.2 Cov Microcontrollers thiab cov chips nco sab nraud Cov Microcontrollers yog qhov tseem ceeb rau cov software system, thiab qhov zoo thiab qhov tsis zoo ntawm lawv cov yam ntxwv tam sim ntawd txiav txim siab qhov tseeb ntawm cov khoom siv hnyav.
