Ukuba ne-Raspberry Pi kuhle kakhulu ekwakheni amaphrojekthi okuzenzakalelayo kwekhaya , kodwa kunemininingwane eyodwa esiye siyikhohlwe ngezinye izikhathi kuze kube sekwephuzile: ukushisa. Kuye ngokuthi yini oyicelayo kudivayisi, iprosesa ingashisa kakhulu, futhi uma ungaqapheli lelo zinga lokushisa, uhlelo luzokwenza lokho okwaziwa ngokuthi i-thermal throttling , lwehlise ijubane lewashi ukuze kuvinjelwe ukushisa ngokweqile. Lokhu kusho ukuthi umshini wakho uzosebenza kancane kunokujwayelekile.
Nakuba lokhu kwakungeyona inkinga kumamodeli okuqala ngoba ayengenamandla kangako, ukufika kwe- Raspberry Pi 5 kushintshe izinto kakhulu. Manje, sidinga ngempela ukubheka amazinga okushisa i-SoC esebenza kuwo, njengoba ukusebenza kwayo kuphakeme kakhulu futhi, ngakho-ke, ikhiqiza ukushisa okukhulu kakhulu. Kulesi sihloko, sizohlola zonke izindlela ezingaba khona zokulinganisa nokulawula lokhu kushisa, kusukela ezindleleni eziyisisekelo kuya ezixazululweni ezithuthukisiwe kakhulu.
Ukulinganisa okusheshayo kusetshenziswa i-terminal
Uma ufuna ukugwema izinkinga futhi udinga nje ukwazi isimo samanje seprosesa, i-terminal ingumngane wakho omkhulu. Kunezindlela eziningana zokuthola lolu lwazi. Enye yezindlela eziqondile kakhulu ukusebenzisa umyalo othi `vcgencmd measure_temp` , obuyisela ngokushesha ukufundwa ngamadigri Celsius.
Kulabo abathanda ukufunda ifayela lesistimu ngqo, ungasebenzisa i -`cat /sys/class/thermal/thermal_zone0/temp` . Imininingwane ebalulekile lapha ukuthi umphumela uboniswa ngama-millidegrees, ngakho-ke udinga ukuhlukanisa inani ngo-1000 ukuze uthole izinga lokushisa langempela. Uma ufuna isibonisi sibuyekeze ngokuzenzakalelayo njalo ngemizuzwana embalwa ngaphandle kokuthayipha umyalo ngokuphindaphindiwe, ungasebenzisa umyalo othi `watch -n X vcgencmd measure_temp` , esikhundleni sika-`X` ngenani elifunekayo lemizuzwana phakathi kokufundwa.
Ukuzenzakalela ngezikripthi ezenziwe ngokwezifiso
Uma ufana nabantu abaningi abakhohlwa imiyalo emide noma abangafuni ukuskrola njalo emlandweni wekhonsoli ngomcibisholo obheke phezulu, ikhambi elifanele ukudala iskripthi se-Bash esisebenzisekayo . Lokhu kukuvumela ukuthi ugoqe imiyalelo ye-CPU ne-GPU kufayela elincane le-.sh.
Ukuze wenze lokhu, mane usebenzise umhleli ofana ne-nano, chaza iziguquguquko ukuze ugcine imiphumela yemiyalo eshiwo ngenhla, bese uzifometha ngomyalo we-`echo` ukuze uwenze ufundeke. Ngemva kokulondoloza ifayela, kubalulekile ukulinika imvume yokusebenzisa umyalo we-`chmod +x`, okukuvumela ukuthi usebenzise isilinganiso ngomyalo owodwa kusuka kunoma iyiphi ifolda ohlelweni.
Ukulawula okubonakalayo kanye namathuluzi okudweba
Akudingeki ukuthi konke kube umbhalo omnyama ngemuva okumhlophe. Uma usebenzisa imvelo yedeskithophu ye-Raspberry Pi OS, ungahlanganisa izinga lokushisa ngqo kubha yomsebenzi ephezulu . Chofoza ngakwesokudla kuphaneli, iya kunketho ethi "Engeza/Susa ama-Plugin", bese ukhetha " I-Temp Monitor" noma "I-CPU Temp ." Lokhu kukuvumela ukuthi uhlole ngokushesha isimo sokushisa ngenkathi usebenza ngaphandle kokuphazamisa imisebenzi yakho.
Uma ufuna into enamandla kakhulu futhi enobungcweti, kukhona ithuluzi elibizwa ngokuthi i-Cockpit . Liyi-interface yokuphatha esekwe kuwebhu oyifaka kubhodi yakho yomama bese uyifinyelela kusuka kusiphequluli sanoma iyiphi idivayisi kunethiwekhi yakho yendawo nge-port 9090. I-Cockpit ayikubonisi nje kuphela izinga lokushisa le-CPU kanye nokusetshenziswa kwayo ngamagrafu omlando, kodwa futhi ikuvumela ukuthi uphathe izinsizakalo, ubuyekeze isofthiwe, futhi uqaphe i-RAM kanye nesitoreji ngaphandle kokubhala umugqa owodwa wekhodi.
Ukuqapha okuthuthukisiwe kanye nezinsizakalo zamafu
Kulabo abathatha amaphrojekthi abo baye ezingeni elilandelayo, kunezinketho ezifana ne -PiCockpit , enikeza imodyuli ebizwa ngokuthi i-PiStats yokubona ukusebenza kwe-chip nokushisa ngamagrafu anemininingwane. Kuyisisombululo esilula kakhulu uma unamabhodi amaningi futhi ufuna ukuhlanganisa ukuqapha kusuka endaweni eyodwa.
Kukhona ukusetshenziswa okuyinkimbinkimbi nakakhulu okuhlanganisa amapulatifomu e-IoT njenge-OKdo Cloud . Kulezi zimo, i-Raspberry Pi ithumela idatha yokushisa efwini ngamaphrothokholi e-TCP/IP, futhi le datha ingabukwa kuzibonisi ezikude ezihlelwe ku-Python noma izinhlelo zokusebenza zeselula, okuvumela ukuqapha okuphelele okukude kusuka noma kuphi emhlabeni.
Imikhawulo ebalulekile namathiphu okupholisa
Kufanele siqale nini ukukhathazeka? Nakuba imodeli ngayinye ihlukahluka, ukugoba okushisa ngokuvamile kuba yinkinga lapho amazinga okushisa edlula ama-60°C kumamodeli afana ne-Pi 3+, kuyilapho ku-Raspberry Pi 4 umkhawulo uphakeme, cishe ama-80-85°C. Ungahlola ukuthi ibhodi lakho liye labhekana nokwehla kokusetshenziswa komyalo othi `vcgencmd get_throttled`.
Uma uqaphela ukuthi amanani aphezulu kakhulu, kunezindlela eziningana zokwehlisa ama-decibel okushisa. Okulula ukufaka ama-heatsink e-aluminium noma e-anodized aluminium ku-SoC. Uma lokho kunganele, ifeni esebenzayo yisisombululo esiphezulu, esidingeka kakhulu ku-Raspberry Pi 5. Amanye amaqhinga awusizo afaka phakathi ukubeka ibhodi ngokuqondile ukuze kuthuthukiswe ukuhamba komoya, ukususa i-casing yepulasitiki evimbelayo, noma ukusebenzisa ama-cases aklanyelwe ukushabalalisa ukushisa, njenge-cases ze-aluminium ze-FLIRC.
Ukwazi ukuqapha ukushisa, kungaba ngemiyalo esheshayo, amaphaneli ewebhu afana ne-Cockpit, noma ukuhlanganiswa kwamafu, kubalulekile ukuqinisekisa ukuthi ukusebenza kwehadiwe kuhlala kuzinzile futhi ukusebenza kuyahambisana. Ukuhlanganisa isofthiwe yokuqapha nokupholisa okufanele, njengamafeni noma ama-heatsink, kuvumela i-Raspberry Pi ukuthi iphathe imithwalo yemisebenzi esindayo ngaphandle kwengozi yokuwohloka noma ukwehla kwesivinini okungalindelekile.
