Qhov kev khiav hauj lwm kub txwv yog 85 ° C , thiab vim li ntawd, Raspberry Pi yuav tsum pib ua kom lub zog ua haujlwm ntawm qhov kub ntawm 82 ° C. Hauv lwm lo lus, qhov no yog xov xwm txhawj xeeb.
Raws li qhov no, qhov kub thiab txias yuav tsum Raspberry Pi khiav ntawm?
Raws li txoj cai, Raspberry Pi Foundation pom zoo tias qhov kub ntawm koj lub Raspberry Pi ntaus ntawv yuav tsum qis dua 85 degrees Celsius kom nws ua haujlwm zoo. Qhov ntawd yog qhov siab tshaj plaws. Tab sis nws yuav pib throttling ntawm 82 degrees Celsius.
Ib yam li ntawd, kuv yuav txheeb xyuas kuv qhov ntsuas kub CPU ntawm kuv Raspberry Pi li cas? Muaj lwm cov lus txib uas koj tuaj yeem siv tau tau qhov system kub ; miv /sys/class/thermal/thermal_zone0/ temp . Txhawm rau siv qhov hloov pauv kub hais kom ua thiab import nws rau hauv Python; Ua ntej, sau ntawv plhaub rau tau lub sijhawm system thiab khaws cia rau hauv cov ntaub ntawv hauv cov npe tam sim no.
Tom qab ntawd, koj siv Raspberry Pi qhov ntsuas kub li cas?
Txuas tus pin 1 rau hauv av GPIO tus pin (labeled GND ntawm AdaFruit connector). Txuas tus pin 2 rau GPIO tus pin 4 (labeled # 4 ntawm AdaFruit connector). Muab 4.7kΩ resistor ntawm tus pin 2 thiab tus pin 3 ntawm tus kub sensor . Tig lub Pi ntawm, ces muab koj tus ntiv tes tawm tsam tus sensor.
Puas yog Raspberry xav tau txias?
Tsis yog. Cov nti siv nyob rau hauv Raspberry Pi yog sib npaug rau ib nti siv hauv lub xov tooj ntawm tes, thiab ua tsis kub txaus rau xav tau tej yam tshwj xeeb cua txias . Tsis yog, nws ua tsis yog xav tau a cua txias qhov system. Yog tias CPU kub dhau (> 85C) nws yuav thim rov qab qhov nrawm.

Dab tsi yog txias thaub qab thiab kub thaub qab?
Qhov sib txawv ntawm qhov kub thiab txias thaub qab hauv oracle. Kev thaub qab txias yog ua tiav thaum tsis muaj cov neeg siv kev ua haujlwm mus nrog lub kaw lus. Kuj hu ua offline backup, yog coj thaum lub database tsis khiav thiab tsis muaj cov neeg siv nkag rau hauv. Ib tug kub backup yog npaum li cas thaum lub database yuav tsum tau khiav txhua lub sij hawm
Dab tsi yog qhov txawv ntawm lub tshuab cua txias thiab lub ntsuas hluav taws xob?
Xyuas ua ntej koj yuav. Feem ntau ib kab txias yuav tsum tiv thaiv koj ntawm surges thiab sages nyob rau hauv kab hluav taws xob xws li xim av outs. Lub surge protector yuav tsis tiv thaiv koj ntawm sags uas tuaj yeem ua rau koj cov khoom puas. Cov kab txias txias ua haujlwm los ntawm kev siv qhov sib txawv input voltage thiab tswj nws mus rau ib qho chaw ruaj khov
Qhov txawv ntawm qhov chaw kub thiab qhov chaw txias yog dab tsi?
Thaum lub chaw kub kub yog ib daim qauv ntawm cov chaw khaws ntaub ntawv nrog tag nrho koj cov khoom siv kho vajtse thiab software ua haujlwm nrog koj lub xaib thawj zaug, qhov chaw txias tau muab tshem tawm - tsis muaj server hardware, tsis muaj software, tsis muaj dab tsi. Kuj tseem muaj qhov chaw sov uas nyob nruab nrab ntawm qhov chaw kub thiab qhov chaw txias los ntawm cov khoom siv
Dab tsi yog qhov zoo sib xws thiab qhov txawv ntawm relays thiab PLC yog dab tsi?
Relays yog electro-mechanical keyboards uas muaj coil thiab ob hom kev sib cuag uas tsis yog NO & NC. Tab sis Programmable Logic Controller, PLC yog lub khoos phis tawj me uas tuaj yeem txiav txim siab raws li qhov kev zov me nyuam thiab nws cov tswv yim & tso tawm
Dab tsi yog qhov txawv ntawm flash point thiab qhov hluav taws kub?
Rau cov kua, flash point qhia qhov qis tshaj qhov kub ntawm qhov, yog tias qhov sib txawv ntawm qhov hluav taws kub (sayspark / hluav taws) yog bro Fire point, ntawm qhov tod tes, yog qhov qis tshaj qhov kub ntawm qhov, txawm tias tsis muaj qhov hluav taws kub, qhov sib tov (cua-vapor thiab liquidsurface) catches hluav taws
