Ukusungula Izinto Ezintsha Kumabhethri E-Drones Nama-UAV
Ukuthuthukiswa kwama-drone kanye nezimoto zasemoyeni ezingenabantu (ama-UAV) kuye kwashesha kakhulu eminyakeni yamuva nje. Ama-drone awasewona nje amathoyizi okuzilibazisa, kodwa aseye aba amathuluzi abalulekile emikhakheni eminingi: ukumaka nokuhlola, ukuhlolwa kwengqalasizinda, ezolimo ezinembile, ezokuthutha, ukusesha nokuhlenga, ngisho nezinhlelo zokusebenza zempi. Kodwa-ke, ngemuva kwentuthuko yamakhamera, izinzwa, ama-autopilot, kanye nokuxhumana, kukhona ingxenye eyodwa evame ukuba "umkhawulo" oyinhloko wamakhono e-drone: ibhethri. Ukukhuthazela endizeni, ukuphepha, isisindo, kanye nokuthembeka komsebenzi kuncike kakhulu kubuchwepheshe bebhethri obusetshenziswayo. Lesi sihloko sixoxa ngezinto ezintsha ezahlukahlukene zebhethri eziqhuba ukusebenza kwe-drone kanye ne-UAV, kanye nezinselele kanye neziqondiso zesikhathi esizayo.
Kungani amabhethri eyinhloko yokusungula izinto ezintsha ngama-drone?
Ama-drone ayizinhlelo ezithinta kakhulu isisindo. Igremu ngalinye elengeziwe kumele "likhokhelwe" ngokusetshenziswa kwamandla amaningi ukuze kukhiqizwe ukuphakamisa. Ngenxa yalokho, amabhethri e-drone ngokufanele abe namandla amaningi (ngesikhathi eside sokundiza), angaletha imisinga ephezulu (yokusuka, ukuqondisa okusheshayo, noma ukuthwala imithwalo), ahlale ephephile, futhi amelane nemijikelezo yokushaja ephindaphindwayo. Ngakolunye uhlangothi, izinhlelo zokusebenza zangempela zivame ukudinga ukushaja okusheshayo nokusebenza ezindaweni eziningi zokushisa, okuhlanganisa ukushisa okukhulu kanye nokubanda okukhulu.
Sekuyiminyaka eminingi, amabhethri e-LiPo (Lithium Polymer) abe yintandokazi yama-drone e-multirotor ngenxa yamandla awo aphezulu wamanje. Kodwa-ke, amabhethri e-LiPo nawo anezici ezidinga ukuqapha: asengozini enkulu yokulimala ngokomzimba, asengozini "yokukhukhumeza," futhi adinga izinqubo zokushaja ezihlelekile kanye nokugcina. Ukusungulwa kwamabhethri kubhekana nesidingo semboni samabhethri anamandla futhi aphephile.
Ukuvela kwe-chemistry yebhethri: kusukela ku-LiPo kuya emndenini we-lithium ohlukahlukene kakhulu
1. I-lithium-ion enamandla aphezulu (i-Li-ion)
Ngemisebenzi edinga isikhathi eside sokundiza, amanye amapulatifomu e-UAV ashintsha kusuka ku-LiPo aye ku-Li-ion enamaseli ayisilinda (isb., 18650 noma 21700) noma amaseli esikhwama anamandla aphezulu. I-Li-ion ngokuvamile inobuningi bamandla obuphezulu kune-“C” LiPo “ephezulu”, okwenza ifaneleke ezindizeni ze-VTOL ezinamaphiko aqinile noma ezihlanganisiwe ezingadingi ugesi omkhulu ngaso sonke isikhathi. Izinselele yikhono logesi eliphakeme kanye nokuphathwa kokushisa—lapho kudingeka izidingo zamandla aphezulu, ukusebenza kwe-Li-ion kungonakalisa futhi kungenzeka ukwakheka kokushisa. Izinto ezintsha kule ndawo zifaka phakathi ukukhetha amaseli anamandla aphezulu, imiklamo yamaphakethe ehlisa ukumelana kwangaphakathi, kanye ne-BMS ehlakaniphile (Izinhlelo Zokuphatha Ibhethri).
2. I-LiFePO4 (LFP) yokuphepha nokuphila isikhathi eside
I-chemistry ye-LFP yaziwa ngokuthi izinzile kakhulu ekushiseni futhi inokuphila isikhathi eside komjikelezo. Kuma-UAV asebenza eduze kwabantu, ezindaweni zezimboni, noma ngezidingo zokusebenza ezidinga izikhathi zomjikelezo ophezulu (isibonelo, ama-drone okuhlola andiza kaningi ngosuku), i-LFP iyindlela ekhangayo. Inkinga ukuthi iphansi kakhulu, okuholela ezikhathini ezimfushane zokundiza ngesisindo esifanayo. Ukusungula izinto ezintsha ku-LFP kugxile ekwandiseni ubuningi bamandla, ekuthuthukiseni ukwakheka kwephakethe, kanye nokwenza ngcono uhlelo ukuze kuncishiswe isisindo esiphelele.
3. I-Lithium-sulfur (Li-S) kanye ne-solid-state: abantu abazongenela ukhetho lwesikhathi esizayo
I-Lithium-sulfur ithembisa ubuningi bamandla obuphezulu kakhulu kune-lithium evamile. Ngokwethiyori, i-Li-S ingadlula i-400 Wh/kg, okungenzeka ukuthi yandise kakhulu isikhathi sokundiza kwe-drone. Kodwa-ke, i-Li-S isabhekene nezinkinga ezifana nokuwohloka okusheshayo, impilo yomjikelezo elinganiselwe, kanye nenkinga "yomphumela we-shuttle" ehlisa ukusebenza kahle. Okwamanje, amabhethri e-solid-state anikeza ithemba elikhulu maqondana nokuphepha kanye nobuningi bamandla, njengoba esebenzisa ama-electrolyte aqinile amelana kakhulu nokuvuza futhi anganciphisa ingozi yokubaleka kokushisa. Ngenkathi ucwaningo oluningi kanye nokuthuthukiswa kwe-prototype kuqhubeka, izindleko kanye nokulungela ukukhiqizwa kwesisindo kusalokhu kuyinselele.
Ukuthuthukiswa komklamo wephakethe: akukhona nje ngamaseli
Ngokuvamile, izinto ezintsha ezinkulu azigcini nje ngokwakheka kweseli, kodwa nangendlela iphakethe eliklanywe ngayo. Ama-drone adinga amabhethri angaletha amandla ngempumelelo ngaphandle kokulahlekelwa ukushisa okuningi.
1. Umklamo ongenatafula kanye nokumelana okuphansi
Eminye imiklamo yamaseli yesimanje inciphisa ukumelana kwangaphakathi ngezakhiwo ezithile ze-electrode. Lokhu kuphumela ekugelezeni kwamandla kagesi okuzinzile, ukukhiqizwa kokushisa okuncishisiwe, kanye nokwehla kwamandla kagesi okuncishisiwe lapho i-throttle ikhuliswa.
2. Izixhumi nezintambo ezisebenza kahle kakhulu
Ukulahlekelwa amandla kwenzeka nasezixhumini, ekusondweni, nasezintanjeni. Imboni yama-drone ithuthukisa izixhumi eziphephile, ezingadlidlizi, nezingenawo umoya ophansi. Lokhu kuthinta ngqo ukusebenza kahle kanye nokushisa kokusebenza.
3. Ukuphathwa kokushisa okuhlanganisiwe
Kuma-UAV ezimboni nakwezempi, kokubili izinhlelo zokupholisa ezingasebenzi kanye nezisebenzayo ziya ngokuya zivamile. Ukupholisa okungenzi lutho kungafaka phakathi ama-heatsink, izinto ezihlanganisiwe ezihlakaza ukushisa, kanye nemiklamo yokuhamba komoya esebenzisa ukuhamba komoya ngesikhathi sokundiza. Ukupholisa okusebenzayo, ngenkathi kunezela ubunzima, kungagcina ukusebenza kwebhethri ngesikhathi sokusebenza okunamandla.
I-BMS ehlakaniphile: amabhethri aya ngokuya “eba nengqondo” kakhulu
Kuma-drone athanda ukuzilibazisa, amaphakethe ebhethri avame ukuba "yiziwula," ahlinzeka ngamandla kuphela ngaphandle kokuxhumana kwedatha okucebile. Kuma-UAV ochwepheshe, le ndlela iyashintsha. Ama-BMS ahlakaniphile manje ayisihluthulelo sokuphepha nokusebenza kahle.
– Ukuqapha iseli ngalinye: i-voltage yeseli ngalinye, izinga lokushisa, kanye nogesi kubhekwa ngesikhathi sangempela ukuvimbela ukukhishwa ngokweqile noma ukushaja ngokweqile.
– Ukulinganisa i-SoC kanye ne-SoH (Isimo Sokushaja/Isimo Sempilo): kusiza abashayeli bezindiza noma abashayeli bezindiza abazenzakalelayo ukubikezela isikhathi sokundiza esisele ngokunembe kakhudlwana, hhayi nje ngokusekelwe ku-voltage.
– Ukuvikelwa kanye nokuphepha: ibhethri linganqamula ugesi uma kwenzeka isimo esingavamile, noma lithumele isexwayiso kusenesikhathi ohlelweni lokulawula izindiza.
– Ukuxhumana kwedatha: amanye amaphakethe asekela izinqubo zokuxhumana ukuze isilawuli sendiza sikwazi ukulungisa iphrofayili yamandla, sinciphise i-throttle emazingeni okushisa aphezulu, noma sihlele ukubuyela ekhaya ngobuhlakani.
Ukusungula izinto ezintsha kwe-BMS nakho kuya ngokuya kushintsha ngokuya ekusebenziseni ama-algorithms okubikezela aqhutshwa idatha, ngisho nokufunda komshini, ukuze kuboniswe ukwehla kwamandla ngokusekelwe kumaphethini okusetshenziswa kwangempela.
Ukushaja okusheshayo kanye nengqalasizinda yamandla
Ubude besikhathi sokundiza bufanelekile, kodwa emkhakheni, ijubane lokujika yilona elidingekayo. Ngakho-ke, ukusungula izinto ezintsha ngophethiloli kubalulekile.
– Ukushaja okusheshayo kwephrofayili ephephile: ukushaja okusheshayo kumele kunake imikhawulo yokushisa kanye nokwamanje ukuze kungasheshi ukuwohloka.
– Ishaja ehlakaniphile enamaphakethe amaningi: ikakhulukazi emisebenzini yezentengiselwano, uhlelo lokushaja olukwazi ukulinganisa amaseli, ukufunda idatha ye-BMS, kanye nokuhlela ukushaja lufiseleka kakhulu.
– Uhlelo lokushintshanisa ibhethri: Ezinye izixazululo zezokuthutha kanye neziteshi zokufaka ama-drone zisebenzisa indlela yokushintshanisa ibhethri ngokuzenzakalelayo. Lokhu kunciphisa isikhathi sokungasebenzi futhi kuvula amathuba okusebenza okuqhubekayo kancane kancane.
– Ukuhlanganiswa kwamandla avuselelekayo: ezindaweni ezikude, izinhlelo zokushaja ezisekelwe kumaphaneli elanga noma ezisekelwe kumajeneretha ahlanganisiwe ziyaqala ukusetshenziswa, yize umthamo kanye nesivinini kuseyinselele.
Ukuphepha: isici esingenakubekwa engcupheni
Umlilo webhethri le-lithium uyingozi enkulu. Ngenxa yokuthi ama-drone avame ukusetshenziswa eduze kwempahla ebalulekile noma izindawo zomphakathi, ukusungula izinto ezintsha zokuphepha kubalulekile ezimvume zokusebenza kanye nokwamukelwa komphakathi.
Ezinye izindlela ezivame kakhulu:
– Ibhokisi eliqinile kanye nezinto ezingashi ukuze kuncishiswe umthelela uma kwenzeka umonakalo.
- Inzwa yokushisa enamaphuzu amaningi ukuze kutholakale ukushisa okusheshayo.
– Ukwakheka kwephakethe le-Modular ukuze ukwehluleka kwengxenye eyodwa kungabangela ukwehluleka okuphelele ngokushesha.
– Izinqubo zokugcina nezokuthutha ezivuthiwe, okuhlanganisa ukusetshenziswa kwezikhwama ezingashi kanye nezindinganiso ezikhethekile zokuthumela.
Kuma-UAV ezimboni, isitifiketi sokuphepha kwebhethri kanye nezindinganiso zemibhalo nazo ziyashintsha, okukhuthaza abakhiqizi ukuba babe sobala kakhudlwana mayelana nokuhlolwa kokuthembeka, imijikelezo, kanye nemikhawulo yokusebenza.
Umthelela wokusungulwa kwebhethri kuzinhlelo zokusebenza ze-drone
Ukusungulwa kwebhethri kunomthelela wangempela endleleni ama-drone asetshenziswa ngayo:
– Ukumapha nokuhlola: isikhathi eside sokundiza sisho indawo ebanzi yokumboza umsebenzi owodwa.
– Ukuhlolwa kwenethiwekhi kagesi kanye namapayipi: ukuthembeka kwephakethe kanye nokubikezela amandla asele kunciphisa ingozi yokufika okuphuthumayo ezindaweni eziyingozi.
– Ukulethwa kwezimpahla: kudinga inhlanganisela yamandla amaningi, ukuphepha, kanye nekhono lokugeleza ukuze kusuke umthwalo.
– Ezolimo ezinembile: ama-drone okufafaza adinga amandla aphezulu kanye nezinhlelo zebhethri ezingamelani nomjikelezo, ngakho-ke ukukhetha ikhemistri kanye nomklamo wephakethe kubalulekile.
Isiqondiso sesikhathi esizayo
Kusukela phambili, ukusungulwa kwebhethri le-drone cishe kuzohamba ngezindlela ezintathu eziyinhloko. Okokuqala, ukwandisa ubuningi bamandla ngokusebenzisa amakhemikhali amasha njenge-Li-S noma amabhethri e-solid-state. Okwesibili, ukuthuthukisa ukuphepha nokuphila kwesikhathi ngokusebenzisa ama-BMS ahlakaniphe kakhulu kanye nemiklamo yamaphakethe aqinile futhi amelana nokushisa. Okwesithathu, ukuqinisa uhlelo lokusebenza—kusukela ezindinganisweni zebhethri, izinhlelo zokufaka ama-docking, ukushintshana okuzenzakalelayo, kuya engqalasizinda yokushaja esebenza kahle.
Ekugcineni, amabhethri awagcini nje ngokuhlinzeka ngogesi, kodwa kunalokho “angumshayeli wesu” womklamo wama-drone: ukuthi angandiza ibanga elingakanani, ukuthi asebenza ngokuphephile kangakanani, nokuthi asekela kanjani imisebenzi ngempumelelo. Ngokuqhubeka nokusungula izinto ezintsha, imikhawulo yakudala yama-drone—isikhathi sokundiza kanye nengozi yebhethri—izoshintsha kancane kancane, ivule ithuba lama-UAV abanzi nathembekile esikhathini esizayo.
