Yeyiphi imifanekiso ethi qatha engqondweni yakho xa ukhankanya ukhuseleko lweperimitha? Into malunga nocingo, "i-dandelion kaThixo" oogogo abanemipu yeendevu, iqela lekhamera kunye nezibane ezikhanyayo? Iialamu? Ewe, kwenzeka into efanayo kwakudala.
Ngokunxulumene neziganeko zamva nje, indlela yokubeka iliso kukhuseleko lwezakhiwo, amacandelo omda wombuso, iindawo zamanzi kunye neendawo ezivulekileyo ezandisiweyo ziya kutshintsha kakhulu.
Kule post ndifuna ukuthetha ngeengxaki zeenkqubo zeklasiki ezikhoyo, kwaye zeziphi iinguqu ezenzekayo ngoku kwintsimi yeenkqubo zokhuseleko. Yintoni esiba yinto yexesha elidlulileyo, kwaye yintoni esele isetyenziswa kwiinkqubo zokhuseleko zanamhlanje.
Bekunjani ngaphambili?
Ndazalelwa kwisixeko esivaliweyo, yaye ukususela ebuntwaneni ndandiqhelene nolawulo, ucingo lwekonkile, amajoni nocingo oluhlabayo. Ngoku andinakukwazi ukucinga ukuba yeyiphi imizamo ye-titanic ethathiweyo ukuqinisekisa ukhuseleko oluthembekileyo kumda wesixeko siphela.
Ukulungiselela indawo yokufakelwa kwezithintelo zekhonkrithi kubandakanya imigxobhozo, iitoni zomhlaba kunye namahlathi. Kufuneka ufake kwakhona i-perimeter sensors (i-detectors), iikhamera, kunye nezibane. Konke oku kufuneka kuxhaswe liqela elikhulu lokusebenza: izixhobo zifuna ukuhlaziywa, ukulungiswa kwexesha kunye nokulungiswa.
Uninzi lwee-detectors zokhuseleko zaqala ukuphuhliswa kwi-USSR emva kwe-70s yenkulungwane yokugqibela kwisixeko sam kunye nezinye izixeko ezininzi. Ukususela ngelo xesha, umgaqo womsebenzi wabo "uphazamisekile" awuzange utshintshe kakhulu, kodwa ukuthembeka kunye nokukhuseleka kwengxolo kuye kwanda. Isiseko se-elementi kunye neteknoloji yemveliso nayo iphuculwe.
Enyanisweni, zombini ngoko kwaye ngoku, i-detector ivelisa kuphela isignali ye-alamu xa i-intruder ifunyenwe kwindawo ekhuselweyo.
Ewe kunjalo, unokongeza imivalo, iikhamera, izibane, ufake iingcingo zekhonkrithi kwaye wenze imigca emininzi yokhuseleko.
Kodwa konke oku kwandisa kuphela iindleko zokhuseleko kwaye ayiphelisi i-drawback ephambili yeenkqubo ze "classical". Ixesha lokuba umaphuli-mthetho onamava "asebenzisane" nomda yimizuzwana embalwa kuphela. Ngaphambi kohlaselo nasemva kwalo, asazi nto ngezenzo zakhe.
Oku kuthetha ukuba awunakuba nexesha lokuthatha amanyathelo ayimfuneko ngaphambi kokuwela umjikelezo wento kwaye ufumane intloko ebuhlungu emva kokuhlasela.
Inokuba yintoni inkqubo yokhuseleko efanelekileyo?
Umzekelo, njengale:
- Khangela umhlaseli phambi kokuwela umda wendawo ekhuselweyo. Kumgama onokuthi, 20-50 yeemitha ukusuka elucingweni. Emva koko inkqubo kufuneka ibeke iliso kwindlela yokuhamba kwe-intruder ngaphambi nangemva kokuhlasela. Umkhondo weentshukumo zomngeneleli kunye nevidiyo ecuphayo iboniswa kwiimonitha zenkonzo yokhuseleko.
- Kwangaxeshanye, inani leekhamera zokhuseleko kufuneka libe lincinci ukwenzela ukuba linganyusi ixabiso lekhompiyutha yokhuseleko kwaye lingagqithisi amehlo kunye nengqondo yamagosa okhuseleko.
Kule mihla, iinkqubo zeradar zokhuseleko (RLS) zinemisebenzi efanayo. Babona izinto ezihambayo, bachonge umntu ongenayo, banqume indawo (uluhlu kunye ne-azimuth) ye-intruder, isantya sakhe, indlela yokuhamba kunye nezinye iiparitha. Ngokusekelwe kule datha, kunokwenzeka ukwenza i-trajectory yentshukumo kwisicwangciso sento. Oku kwenza kube lula ukuxela kwangaphambili intshukumo eyongezelelweyo ye-intruder kwizinto ezibalulekileyo ngaphakathi kwendawo ekhuselweyo.
Umzekelo wokubonisa ulwazi oluvela kwisixokelelwano sokhuseleko se-radar kwimonitha yenkonzo yokhuseleko.
Inkqubo enjalo ye-radar isebenza ngaphakathi kwecandelo lokujonga ukusuka kwishumi lamadigri ukuya kwi-360 degrees kwi-azimuth. Iikhamera zevidiyo zincedisa ukubonwa. Ukusebenzisa idatha ye-radar, iqonga elijikelezayo leekhamera zevidiyo libonelela ngomkhondo obonakalayo we-intruder.
Ukugubungela ngokupheleleyo ummandla wento ene-perimeter ende (ukusuka kwi-5 ukuya kwi-15 km), iirada ezimbalwa kuphela ezine-angle yokujonga ukuya kuma-90 degrees inokwanela. Kule meko, i-locator eye yafumanisa umhlaseli kuqala ibeka iliso kuye kwaye ihlalutye imilinganiselo yentshukumo yakhe de i-intruder ifike kwindawo yokujonga enye i-locator kunye nenye ikhamera yethelevishini.
Ngenxa yoko, isibonelelo sihlala siphantsi kolawulo lomsebenzi wokhuseleko.
Le ngcamango yokwakha inkqubo yokhuseleko inolwazi, iyasebenza kwaye i-ergonomic.
Nanku umzekelo wendlela esebenza ngayo inkqubo enjalo:
Ukulungele ukuqhubeka nokupapasha. Umzekelo, malunga neenkqubo zokuchasa ii-UAVs kunye needrones kunye neecingo ezihlanganisiweyo zanamhlanje (enye indlela yocingo oluqinisiweyo lwekhonkrithi).
