Ukuthuthukisa Izikhungo Zokushintsha Amaselula Ngezixazululo Ezithuthukisiwe ze-PCB

Ezweni lanamuhla elixhumeke kakhulu, izinhlelo zokuxhumana ziwumgogodla wokusebenzelana komhlaba wonke, izimboni ezishayelayo, amabhizinisi, nobudlelwano bomuntu siqu. Ukufika kwe-5G, ukukhuphuka kwe-Intanethi Yezinto (IoT), kanye nezidingo ezikhula njalo zezinhlelo zokusebenza ezidinga idatha kwenze amanethiwekhi ezokuxhumana ayinkimbinkimbi futhi abaluleke kakhulu. Enye yezingxenye ezibaluleke kakhulu ezisiza ekugcineni ukuxhumana okungenazihibe kuwo wonke la manethiwekhi ayinkimbinkimbi i-Mobile Switching Center (MSC).

I-Mobile Switching Center idlala indima ebalulekile ekulawuleni ukuxhumana kweselula, iqinisekisa ukuthi izingcingo, imilayezo yombhalo, namaseshini edatha kuhanjiswa ngempumelelo ngenethiwekhi. Kodwa-ke, ngemuva kwamandla anamandla e-MSC kunengxenye ebalulekile evame ukunganakwa: Amabhodi Esifunda Aphrintiwe (PCBs).

Kwa-Highleap Electronic, sigxile ekukhiqizweni kwe-PCB kanye nokuhlanganiswa kwe-PCB kwemishini yokuxhumana yobuchwepheshe obuphezulu, okuhlanganisa nezikhungo zokushintshana ngeselula. Kulesi sihloko, sizohlola ukuthi ama-PCB abaluleke kangakanani ekusebenzeni kwe-MSC nokuthi kungani ubuchwepheshe bethu ekuklanyweni nasekuhlanganisweni kwe -PCB busenza sibe ngumlingani othembekile emhlabeni wezokuxhumana.

Ukuqonda Isikhungo Sokushintsha Iselula (MSC) Nokubaluleka Kwaso

I-Mobile Switching Center (MSC) iyingxenye ebalulekile yengqalasizinda yezokuxhumana ngomakhalekhukhwini, esebenza njengendawo emaphakathi yenethiwekhi ewumongo. Isibopho sayo esiyinhloko ukuphatha umzila wamakholi, ukuphatha ukusayina, nokwengamela ukuphathwa kokunyakaza kuyo yonke inethiwekhi. I-MSC isebenza njengesixhumanisi esibalulekile, exhumanisa izici zenethiwekhi ezihlukahlukene njengezilawuli ze-Base Station Controllers (BSC), Izilawuli Zenethiwekhi Yomsakazo (RNC), kanye Nenethiwekhi Yocingo Eshintshiwe Yomphakathi (PSTN).

I-MSC inesibopho semisebenzi eminingana ebalulekile, okuhlanganisa ukusethwa kwezingcingo, ukunqanyulwa kwezingcingo, ukunikezela phakathi kwemibhoshongo yeselula, ukulandelela indawo, nokuphatha ukuzulazula phakathi kwamanethiwekhi ahlukene. Le misebenzi iqinisekisa ukuthi abasebenzisi bangakwazi ukushaya futhi bamukele amakholi, ukuthumela imilayezo yombhalo, nokugcina izikhathi zedatha, kungakhathaliseki indawo yabo noma inethiwekhi abaxhumeke kuyo. Ngaphandle kwe-MSC, amanethiwekhi eselula ngeke akwazi ukuphatha kahle ukuxhumana kumadivayisi eselula ahlukahlukene kanye namasevisi, akwenze kube yingxenye ebalulekile yanoma iyiphi ingqalasizinda yezokuxhumana.

Iqhaza le-MSC ekuqinisekiseni ukuxhumana okungenazihibe kuzo zonke izingxenye zenethiwekhi yamaselula kanye nabasebenzisi igqamisa ukubaluleka kwayo okubalulekile ezinhlelweni zesimanje zokuxhumana ngomakhalekhukhwini.

Ama-PCB Asinika Kanjani Isikhungo Sokushintsha Iselula

Ama-PCB ayisisekelo sezinto zikagesi zesimanje, ezivumela ukuhlanganiswa kwezingxenye ezihlukahlukene ze-elekthronikhi namasekhethi. Esimeni se-MSC, ama-PCB asetshenziswa kuwo wonke amasistimu angaphansi ambalwa abalulekile. Ake singene endleleni amabhodi esekethe aphrintiwe adlala ngayo indima ebalulekile kulezi zinhlelo.

1. Umzila Wesiginali Nokucubungula

Omunye wemisebenzi ebaluleke kakhulu ye-MSC umzila wesiginali—ukuqondisa izingcingo, imilayezo, namaphakethe edatha phakathi kwabasebenzisi beselula nezinto zenethiwekhi. Lokhu kuhilela ukucubungula isignali yedijithali esezingeni eliphezulu (DSP) kanye nokuguqulwa kwe-analog-to-digital (ADC). Ukuthungathwa nokucutshungulwa kwamasignali kwenziwa ama-PCB asebenza kahle axhumanisa amamojula wehadiwe amaningi ngaphakathi kwe-MSC.

Ama-PCB e-RF (imvamisa yomsakazo) asezingeni eliphezulu kanye nama-PCB okuxhumana ayadingeka ukuze aphathe ukucutshungulwa kwedatha okusheshayo kanye nobuqotho besignali kuma-MSC. Lawa ma-PCB aqinisekisa ukuthi amandla esignali kanye nekhwalithi kuhlala kuphezulu, ngisho nasezindaweni zenethiwekhi eziminyene kakhulu, ngaleyo ndlela kunciphisa ukulahleka kwephakethe noma izingcingo ezilahliwe. Imiklamo ye-PCB ethuthukisiwe, njengebhodi le-HDI (High-Density Interconnect), ivame ukusetshenziselwa ukufaka izifunda eziyinkimbinkimbi ezindaweni ezincane ngenkathi kuqinisekiswa ukudluliswa kwesignali okusebenzayo.

2. Ukulawula kanye Nezinhlelo Zokusayina

Amasistimu okulawula namasignali ngaphakathi kwe-MSC alawula ukugeleza kokuxhumana nemisebenzi yenethiwekhi. Lokhu kufaka iphrothokholi ye-Signaling System 7 (SS7) esetshenziselwa ukusetha ikholi yeselula, i-SIP (Session Initiation Protocol) yamakholi e-VoIP, kanye nezinye izimiso eziyisisekelo ezifana ne-GTP (GPRS Tunneling Protocol) zokuphatha isikhathi sedatha kunethiwekhi ye-3G ne-4G. Lezi zinhlelo zokulawula zinikwa amandla ama-microcontrollers, ama-ASIC (Application-Specific Integrated Circuits), kanye ne-FPGA (I-Field-Programmable Gate Arrays), zonke zixhunywe ngamabhodi esekethe aphrintiwe.

Ama-PCB kulezi zinhlelo kumele aqinisekise ukucutshungulwa kwesignali okuthembekile ngokubambezeleka okuncane, okubalulekile ekuxhumaneni kwesikhathi sangempela. Ngokuhlanganisa izingxenye ezihlukahlukene, ezifana namaphrosesa esignali, amaphrosesa enethiwekhi, namamojula enkumbulo, ama-PCB adlala indima ebalulekile ekulawuleni ukusebenza kwalezi zinhlelo zokusayina, ukuqinisekisa ukunikezwa okushelelayo, nokuletha isevisi engaphazamiseki kubasebenzisi.

3. Ukuxhumana kweRadio Frequency (RF).

I-MSC ihlangana nezinto ezihlukahlukene zenethiwekhi yokufinyelela kumsakazo (i-RAN), njenge-Base Station Subsystems (BSS) nama-eNodeBs kumanethiwekhi e-LTE. Lezi zingxenye zithembele kumasekhethi e-RF ukuze adlulise futhi amukele amasiginali ngamaza omoya. Ukuze uthole ukudluliswa kwesignali okufanele kanye nokunciphisa ukuphazamiseka, ama-RF PCB abalulekile ekuhlanganisweni kwezimpondo, ama-transceiver, nezikhulisi ngaphakathi kohlelo.

Ama-PCB aklanyelwe izinhlelo zokusebenza zemvamisa ephezulu asetshenziswa kuma-MSC ukugcina ubuqotho besiginali, ikakhulukazi ekuxhumaneni kwamaselula kubuchwepheshe be-2G, 3G, 4G LTE, kanye ne -5G obusha . Lawa ma-PCB e-RF adinga ukwenziwa ngcono ukuze anciphise ukulahleka, ukusebenza kahle okuphezulu, kanye nobubanzi bemvamisa ukuze abhekane nezidingo ezikhulayo zamanethiwekhi okuxhumana eselula anamuhla.

4. Ukusabalalisa Nokuphatha Amandla

Izikhungo Zokushintsha Omakhalekhukhwini zidinga ukuphathwa kwamandla okuqinile ukuze kuqinisekiswe ukuthi uhlelo lusebenza ngokuthembekile 24/7. Amasekhethi okusabalalisa amandla kuma-PCB aqinisekisa ukuthi isistimu engaphansi ngayinye ngaphakathi kwe-MSC ithola i-voltage efanele kanye neyamanje ekusebenzeni kwayo. Amasekhethi okuphakela amandla aphinde aphathe izipele zebhethri ukuze kugcinwe ukuqhubeka kwesevisi ngesikhathi sokuhluleka kwamandla.

Ukuphathwa kwamandla kubaluleke kakhulu ezinhlelweni ze-telecom nesikhungo sedatha lapho kudingeka khona ukutholakala okuphezulu. Kwa-Highleap Electronic, siyakuqonda ukubaluleka kwama-PCB okusatshalaliswa kwamandla athembekile kwingqalasizinda yezokuxhumana, futhi siyaqinisekisa ukuthi yonke i-PCB ihlangabezana nezindinganiso eziqinile zokusebenza kahle kwamandla kanye nokuphathwa kokushisa.

5. Izixhumanisi Zokuxhumana Nokuxhumana

I-MSC ixhuma kuma-elementi enethiwekhi ahlukahlukene, okuhlanganisa ama-BSC, ama-RNC, ama-Packet Gateways (PGWs), ama-SGSN, namasistimu angaphandle nge-Ethernet, i-fiber optics, nezinye izixhumi zokuxhumana. Ukuze unike amandla ukudluliswa kwedatha nokuxhumana okunesivinini esikhulu, ama-PCB okusebenza kwenethiwekhi ayadingeka.

Lawa mabhodi okuxhumana ahlinzeka ngokudluliswa kwedatha okushesha kakhulu, ukuxhumana okuphansi kwe-latency, kanye nokudlulisa okungenaphutha ngokusebenzisa izivumelwano ezihlukahlukene, njenge-Ethernet (10G/100G), i-fiber-optic (Gigabit Ethernet), kanye nokuxhumana kweMicrowave. Kuma-MSC, ama-PCB asekela lezi zindawo zokusebenzelana futhi avumele ukuhlanganiswa okungenamthungo nengqalasizinda yezokuxhumana ngocingo.

Ukuphakamisa Izikhungo Zokushintsha Amaseva Ngezixazululo ze-Turnkey PCB

Uma kukhulunywa ngokusebenza okungenazihibe kwama-MSC, yonke imininingwane ibalulekile. Kusukela kuma-PCB ashayela ukucutshungulwa kwesignali nokuphathwa kwamandla kuya ezindaweni ezivalekile ezivikela futhi zithuthukise ukusebenza, yonke ingxenye kufanele isebenze ndawonye ngokungenasici. Kwa-Highleap Electronic, sinikezela ngezinsizakalo zokukhiqiza zikagesi eziya ekupheleni-kuya-ekupheleni—okuhlanganisa ukukhiqizwa kwe-PCB, ukuhlanganisa, nokuhlanganisa indawo ebiyelwe—eklanyelwe ukuhlangabezana nezidingo eziqondile zemboni yezokuxhumana.
