Ngeli xesha lexesha ledijithali, sonke sixhomekeke kwizixhobo ezahlukeneyo ezifana neekhompyuter kunye nezinye izinto zombane ukuze ziqhubeke zisebenzela ukugcina idatha yethu ngononophelo ukuhlalutya okanye ukusetyenzwa. Noko ke, sinokuyithemba njani into yokuba inkcazelo ephuma kwezi zixhobo ichanile okanye inokuthenjwa? Ngenisa i-CRC (i-Cyclic Redundancy Check), esetyenziselwa ukuqinisekisa ukuthembeka kwedatha.
I-CRC ifana nomhloli ojonga ngocoselelo ukuba idatha ifunyenwe okanye ayifunyanwanga ngokuchanekileyo kwaye akatshintshi. AkunakwenzekaNgamanye amaxesha xa uthumela idatha ukusuka apha ukuya phaya, kukho into engahambi kakuhle. I-CRC yale datha yenza inani lezibalo eziqinisekisa ukugcina ukuthembeka kunye nokungenaziphene.
Kukhuseleko lwenethiwekhi yekhompyuter, ulwazi lubaluleke kakhulu. I-CRC ibalulekile kumxholo wokukhangela idatha edluliselwe ukusuka kwesinye isixhobo sothungelwano ukuya kwesinye okanye hayi, nokuba ilahleka ngendlela yayo kwaye xa ifuneka. Oku kubaluleke kakhulu ukugcina inethiwekhi isebenza kakuhle ngaphandle kokuphazamiseka.
I-CRC inokubonakala intsonkothile ekuqaleni, kodwa kukho iindlela ezilula zokuqonda ukuba yintoni kanye eyenza. Ubuninzi be-algorithms ezifana ne-CRC-32 evelele kakhulu isetyenziselwa ukuqinisekisa ukujonga iimpazamo kunye nokhuseleko lwedatha. I-algorithms idlala indima ephambili ekusebenzeni okugudileyo, okungaphazamisekiyo kweenkqubo.
Ngokuhambela phambili kwetekhnoloji, imfuno yokukhusela idatha ibaluleke kakhulu. Nangona i-CRC ilungile ekuboneni iimpazamo kwidatha njengoko idlula ikhonkco, kukho iingxaki ezithile ngokusebenzisa ... Ayinakukwazi ukubona iimpazamo kwidatha ngokwayo kodwa inokuxelela kuphela ukuba kukho nayiphi na impazamo eyenzekayo ngexesha lokudluliselwa.
Amaqonga amaninzi azama ukusombulula ezi ngxaki ngokuhlala ephuhlisa iindlela ezintsha kunye netekhnoloji. Kule mihla, njengoko idatha ifakwa kwidijithali ngesantya esikhawulezayo, oko kukuthi, uninzi lwayo luye lwedijithali (nangona lungekho ngokupheleleyo!), Ukuhanjiswa kolwazi kufuneka kuthembeke. I-CRC iyaqhubeka nokukhusela ilizwe lethu ledijithali kunye notshintshiselwano lwedatha phakathi kwabantu njengoko sihamba kolu tshintsho luguqukayo.
Ukubaluleka kwe-CRC ekukhuseleni idatha yedijithali kuya kufikelela ngakumbi kwixesha elizayo. Sinokulukhusela uthungelwano lwethu ngokuphumeza ubugcisa obutsha kunye nezenzo.
Uluhlu lwemveliso yethu lubandakanya iintsimbi ezininzi ezahlukeneyo ezifana ne-CRC, i-stainless prepainted, i-aluminium galvanized steel, kunye nobhedu. Ezi zinyithi zisetyenziswa kakhulu kushishino lokwakha, ezothutho, namandla, kunye nakwizixhobo zasekhaya. Ukuhlangabezana neemfuno zabathengi abahlukeneyo, sikwabonelela ngeenkonzo ezilungelelanisiweyo ezibandakanya ukuyila kunye nokuvelisa iimveliso zetsimbi ezineenkcukacha ezikhethekileyo ezisekelwe kwiimfuno ezithile zabathengi.
Siqhubeka nokwandisa imarike yethu yehlabathi, kwaye sithumela iimpahla zethu kwi-CRC, eMelika naseAsia ukongeza eAfrika nakwezinye iindawo. Sizuze ukuthenjwa ngabathengi bethu ngokunikezela ngeenkonzo ezikumgangatho ophezulu kunye neemveliso. Kwangaxeshanye, siye saseka ubuhlakani obucwangcisiweyo kunye neenkampani ezininzi ezidumileyo ukuphuhlisa iimarike ezintsha kunye namathuba oshishino.
I-Shandong CRC Xinde Metal Processing yinkampani egxile kwimveliso kunye nokuthengiswa kwezinto eziphezulu zetsimbi, kuquka iipleyiti zentsimbi kunye neekhoyili. Ukutyhubela iminyaka, sizibophelele ekuboneleleni abathengi bethu umgangatho ophezulu wekhabhoni yentsimbi, insimbi engenasici, igalvanized, iiflange zangaphandle ezigqunywe ngombala, iipleyiti zokuphela kweemfumba zesikwere kunye nezinye iimveliso zetsimbi. Siseke ubudlelwane obuqinileyo kunye nexesha elide kunye nabathengi kwihlabathi liphela ngenxa yamava ethu kushishino kunye neqela lobugcisa.
Njengomenzi wemveliso yentsimbi ye-CRC, sihlala sibambelela kwimodeli yeshishini ejolise kumgangatho kunye nejolise kumthengi. Kwinkqubo yemveliso sisebenzisa ezona zixhobo zemveliso zala maxesha kunye nobuchwepheshe kwaye silawula ngokungqongqo ikhonkco ngalinye lemveliso ukuze siqinisekise ukuba umgangatho weemveliso zethu uhlala uphezulu kwimarike. Ukongeza, sineqela lokuhlola umgangatho oqeqeshiweyo oqhuba uhlolo olungqongqo lwebhetshi nganye yemveliso ukuqinisekisa ukuba izinto eziziswe kubathengi ziyahlangabezana nolindelo kunye neemfuno zabo.
