I-SOS: Isiginali Yokucindezeleka kanye Nenguquko Yayo Yomlando
Kusuka ku-Telegraphy kuya kuDijithali, Indaba Yesiginali Yomhlaba Wonke
Ukuzalwa kwe-SOS
Indaba ye-“SOS" Ukucindezeleka isignali iqala ekuqaleni Ikhulu le-20th. Germany kwaba yizwe lokuqala ukwamukela iSOS, eyaziwa ngokuthi Notzeichen, ngo-1905. Yabe seyaziwa emhlabeni wonke lapho ingeyokuqala International Radiotelegraph Convention, ebanjelwe eBerlin e 1906, yamukela isignali phakathi kwemithetho yayo. Isiginali ye-SOS, enamachashazi amathathu, odwi abathathu, namachashazi amathathu, yaqala ukusebenza ngo July 1, 1908. Lesi siginali yekhodi ye-Morse yakhethwa ngenxa yobulula nokucaca kwayo ekudluliseni, futhi naphezu kokuba ingenayo incazelo yama-alfabhethi, yaziwa ngokujwayelekile ngokuthi “i-SOS”.
I-SOS ku-Titanic Disaster
I-SOS yazuza udumo emhlabeni wonke ngesikhathi sokucwila kwe- I-Titanic ngo-1912. Nakuba yamukelwa ngokusemthethweni ngo-1908, “I-CQD” isignali yahlala isetshenziswa, ikakhulukazi ezinkonzweni zaseBrithani. Endabeni ye-Titanic, isignali yokuqala eyathunyelwa kwakuyi-"CQD", kodwa ngokusikisela kuka-Harold Bride, isikhulu sesibili somsakazo, yahlanganiswa ne-"SOS". I-Titanic imele esinye sezimo zokuqala lapho isignali ye-SOS isetshenziswe eceleni kwe-CQD esimweni esiphuthumayo sasolwandle, okuphawula ukuguquka kokwamukelwa kwe-SOS njengesignali yokucindezeleka kwendawo yonke.
I-SOS kuSiko Elidumile Nobuchwepheshe Besimanje
I-SOS isingenile isiko elidumile njengophawu lomhlaba wonke lokucela usizo ezimeni eziphuthumayo. Ivele ezincwadini, emafilimini, emculweni, nasemidwebeni yobuciko, ibamba iqhaza elibalulekile ezakhiweni ezilandisayo futhi yaba ubizo lokuthatha isinyathelo ngokushesha. Nakuba ikhodi ye-Morse ingabalulekile kangako ngentuthuko kwezokuxhumana ngomsakazo, i-SOS isalokhu iwusizo ezimeni eziphuthumayo ezingazodwa. Namuhla, i-SOS ihlanganiswe emishinini eminingi ye-elekthronikhi nezinhlelo ezingaphakathi ezimotweni, ezivamise ukwenziwa kusebenze ngokucindezela inkinobho elula. Lokhu kuhlanganiswa kobuchwepheshe kukhombisa ukubaluleka okubalulekile komqondo we-SOS, ngisho nokuthuthuka ezindleleni zokuxhumana.
Ukuziphendukela Kwemvelo Okuqhubekayo kwe-SOS
The umlando we-SOS isignali ibonisa indlela isignali elula yekhodi ye-Morse ibe uphawu lomhlaba wonke lokuhlenga. Ukuziphendukela kwemvelo kwayo, kusukela ekusetshenzisweni kokuqala kocingo kuya kusiginali yokucindezeleka ehlanganisiwe kubuchwepheshe besimanje, kubonisa ukubaluleka kwayo okuqhubekayo kanye nokuvumelana nezimo ezinguqukweni zobuchwepheshe. Ngisho noma indlela yokudlulisa i-SOS isishintshile ngokuhamba kwesikhathi, incazelo yayo eyisisekelo njengesicelo sosizo ezimeni ezibucayi ihlala ingashintshile.
