FPV umamkeli wevidiyo
Isiqulatho
FPV iVideo Receiver
Kule vidiyo, Ndiza kubonisa unxibelelwano phakathi kwe-FPV VTX transmitter kunye nomamkeli.
Isixhobo soqwalaselo lweparamitha yothumelo sifuna igalelo lamandla eyongezelelweyo ye-12V. I-transmitter nayo idinga igalelo lamandla e-12V.
Isikrini somdwelisi sibonisa iparamitha yothumelo lwangoku. Ngokusebenzisa umcwangcisi womthumeli, ungatshintsha amaxesha osasazo, bandwidth, inombolo yokuvula, etc. Ukuba usebenzisa okokuqala, awudingi ukutshintsha nayiphi na iparameters. Ukusetwa okungagqibekanga sele kugqwesile kwaye kuvavanywa kumzi-mveliso.
Nanku umamkeli, esele inesikrini esincinci kunye namaqhosha. Iiparamitha apha ziyafana ne-transmitter. Kukho kwakhona ixabiso le-SNR kunye ne-PW, I-SNR ngumgangatho wesiginali kwaye i-PW ngamandla omqondiso.
Amaxabiso e-SNR kunye ne-PW abaluleke kakhulu. Kufuneka ujonge ezi parameters rhoqo.
Umdwelisi wenkqubo kunye negalelo levidiyo kwi-transmitter yabelana ngendlela efanayo yokufaka ujongano. Ngoko ke kuqala siqhawula unikezelo lwamandla lomdwelisi wenkqubo. Susa umdwelisi kwaye uqhagamshele intambo yokufaka ividiyo. Xa usebenza, Nceda ukhumbule ukukhulula intambo yamandla yesithuthi kwaye ungayisebenzisi ngelixa sisebenza.
Ngoku sinika isidlulisi isiginali yokufaka ividiyo. Emva koko qhagamshela amandla kwi-transmitter. Sibeka i-transmitter kwiphepha letsimbi ukukhawulezisa ukutshatyalaliswa kobushushu be-transmitter. Kwidrone, ungasebenzisa i-propeller ukuhambisa ubushushu kwi-transmitter.
Yima imizuzwana embalwa, kunye nomqondiso wevidiyo oza kuvela kwi-FPV yevidiyo ebonisa umamkeli. Umthumeli uxhasa igalelo levidiyo ye-SD 720P, kwaye umamkeli uxhasa i-HDMI 1080P imveliso yevidiyo. I-transmitter ayisebenzisi igalelo le-HDMI kuba i-SD ine-latency ephantsi kunye nesantya sokufaka ikhowudi ngokukhawuleza. Njenge-FPV transmitter, i-latency ephantsi ibaluleke ngaphezu komgangatho we-1080P womfanekiso.
Sitshintshe isignali yevidiyo ngekhamera. Umfanekiso wevidiyo uzinzile kwaye ucocekile, ngaphandle kwamahlwantsi ekhephu okanye iimosaics.
kulonwabiso
Ixabiso le-SNR limele umgangatho wesignali engenazingcingo ukusuka kumthumeli ukuya kumamkeli.
Ixabiso elikhulu le-SNR li, ngcono uphawu lwangoku. Ixabiso lisezantsi, imbi ngakumbi uphawu lwangoku. Xa i-SNR ingaphantsi kune 5 ukuba 6, Umqondiso osuka kumthumeli ukuya kumamkeli uya kuphazamiseka kwaye umfanekiso wommkeli uya kudodobala. Okanye kuvela i-mosaic.
Ngeli xesha, ukuphakama kwe-eriyali yomamkeli kufuneka kuhlengahlengiswe okanye indawo yomamkeli kufuneka ishukunyiswe ukoyisa imiqobo ethile ukuze ulwamkelo lwesiginali lubengcono kwaye ixabiso le-SNR libuyele ngaphezulu kwe-6 ~ 7.
Ixabiso le-SNR liya kuboniswa kuphela emva kokuba i-transmitter ivuliwe. Ngokubanzi, ixabiso le-SNR lijikeleze i-15dB, kunye nomqondiso wevidiyo uzinzile kakhulu. Ukuba ixabiso le-SNR lingaphantsi kwe-6dB, isiginali yevidiyo iya kumisa okanye iphele.
PW
Ngokumalunga nexabiso le-PW lomamkeli, le parameter inokukhangela ukuba ngaba umamkeli unokuphazamiseka kwifrikhwensi yangoku. Akukho mfuneko yokuvula i-transmitter. Kufuneka kuphela ukudibanisa i-eriyali yomamkeli kwaye uyivule ukuze uqwalasele ixabiso le-PW. Ukuba ixabiso le-PW li -80, indawo yangoku iphazamisana ne-eriyali yomamkeli. Ukuba ixabiso le-PW li -90, indawo yangoku icacile kwaye akukho kuphazamiseka kwi-eriyali yomamkeli.
Ukuba ixabiso le-PW lingaphantsi kwe -80, inokuba kungenxa yokuba isidluliseli sisondele kakhulu. Ngeli xesha, kufuneka ulungise umgama phakathi komthumeli kunye nomamkeli ngokufanelekileyo.
