What is the difference between Bluetooth, 2.4G and 433 for wireless scanners?

Izikena zebhakhodi ezingenantambo okwamanje ezisemakethe zisebenzisa lobu buchwepheshe bokuxhumana obubalulekile

Ukuxhumeka kwe-Bluetooth:

Ukuxhumana kwe-Bluetooth kuyindlela evamile yokuxhumaizikena ezingenantambo. Isebenzisa ubuchwepheshe be-Bluetooth ukuxhuma isithwebuli ngokungenantambo kudivayisi. Ukuxhumana kwe-Bluetooth kubonakala ngokukwazi ukuzivumelanisa nezimo kuwo wonke amadivaysi e-Bluetooth, ukusebenzisana okuphezulu, ibanga eliphakathi nendawo kanye nokusetshenziswa kwamandla okusesilinganisweni.

2.4G uxhumano:

Ukuxhumana kwe-2.4G kuyindlela yokuxhumana engenantambo esebenzisa ibhendi engenantambo engu-2.4G. Inebanga elide kanye nesivinini esikhulu sokudlulisela phambili, okuyenza ifaneleke izinhlelo zokusebenza ezihamba amabanga amade noma lapho kudingeka khona amazinga aphezulu okudlulisela. Uxhumano lwe-2.4G ngokuvamile lusebenzisa isamukeli se-USB ukubhanqa nedivayisi, okumele ixhunywe embobeni ye-USB yedivayisi.

433 uxhumano:

Ukuxhumana kwe-433 kuyindlela yokuxhumana engenantambo esebenzisa ibhendi yomsakazo engu-433MHz. Inebanga elide lokudluliswa nokusetshenziswa kwamandla amancane, okuyenza ifaneleke izinhlelo zokusebenza ezidinga ukudluliswa kwebanga elide kanye nokusetshenziswa kwamandla amancane. Ukuxhumeka kwe-433 kuvame ukubhangqwa nesamukeli se-USB esidinga ukuxhunywa embobeni ye-USB yedivayisi.

Kubalulekile ukukhetha ukuxhumana okulungile kwezidingo ezithile. Ngamabanga amafushane kanye nezidingo zamandla aphansi, khetha uxhumano lwe-Bluetooth; kumabanga amade namazinga aphezulu edatha, khetha uxhumano lwe-2.4G; ukuze uthole amabanga amade nezidingo zamandla aphansi, khetha uxhumano lwe-433. Izinto ezinjengokuhambisana kwedivayisi, izindleko kanye nobunzima bokulungiswa kufanele kucatshangelwe.

Uma unentshisekelo noma umbuzo ngesikhathi kukhethwa noma kusetshenziswa noma yisiphi isithwebuli sebhakhodi, sicela uchofoze isixhumanisi esingezansi uthumele umbuzo wakho kumeyili yethu esemthethweni.(admin@minj.cn)ngqo!MINJCODE izibophezele ocwaningweni nasekuthuthukisweni kobuchwepheshe besithwebuli sebhakhodi kanye nemishini yokufaka isicelo, inkampani yethu inesipiliyoni seminyaka engu-14 sembonini emikhakheni yobungcweti, futhi iye yaqashelwa kakhulu iningi lamakhasimende!

Umehluko phakathi kwe-2.4G ne-Bluetooth:

Ubuchwepheshe obungenawaya be-2.4GHz ubuchwepheshe bokudlulisa okungenazintambo bebanga elifushane, obunokudluliselwa kwezindlela ezimbili, ukunqanda ukuphazamiseka okuqinile, ibanga elide lokudlulisela (ibanga elifushane lobuchwepheshe obungenantambo), ukusetshenziswa kwamandla okuphansi, njll. Ubuchwepheshe be-2.4G kungaxhunywana nabo phakathi kuka-10 amamitha. kukhompuyutha.

Ubuchwepheshe be-Bluetooth buyiphrothokholi yokudlulisa okungenantambo esekelwe kubuchwepheshe be-2.4G. Ihlukile kobunye ubuchwepheshe be-2.4G ngenxa yemithetho ehlukene esetshenziswayo futhi ibizwa ngokuthi ubuchwepheshe be-Bluetooth.

Eqinisweni, i-Bluetooth ne-2.4G ubuchwepheshe obungenawaya amagama amabili ahlukene. Kodwa-ke, awukho umehluko phakathi kwalokhu okubili ngokuya ngemvamisa, zombili zikubhendi ye-2.4G. Qaphela ukuthi ibhendi ye-2.4G ayisho ukuthi iyi-2.4G. Eqinisweni, izinga le-Bluetooth likumabhendi angu-2.402-2.480G. Imikhiqizo ye-2.4G idinga ukuhlonyiswa nomamukeli. Amagundane anamuhla angenantambo e-2.4G afika nesamukeli; Amagundane e-Bluetooth awadingi umamukeli futhi angaxhunywa kunoma yimuphi umkhiqizo osebenza nge-Bluetooth. Okubaluleke kakhulu, umamukeli kugundane elingenantambo le-2.4G lingasebenza kuphela kumodi eyodwa kuya kokunye, kuyilapho imojula ye-Bluetooth ingasebenza kumodi eyodwa-kuya-kwabaningi. Izinzuzo ziza nokubi. Imikhiqizo esebenzisa ubuchwepheshe be-2.4G iyashesha ukuxhuma, kuyilapho imikhiqizo esebenzisa ubuchwepheshe be-Bluetooth idinga ukubhanqa, kodwa imikhiqizo yobuchwepheshe be-2.4G nayo idinga imbobo ye-USB, phakathi kwezinye izinzuzo kanye nokubi. Njengamanje, imikhiqizo eyinhloko esebenzisa ubuchwepheshe be-Bluetooth amahedisethi e-Bluetooth nezipikha ze-Bluetooth. Imikhiqizo yobuchwepheshe be-2.4G ikakhulukazi amakhibhodi namagundane angenantambo.

Umehluko phakathi kwe-Bluetooth ne-433:

Umehluko omkhulu phakathi kwe-Bluetooth ne-433 amabhande omsakazo abawasebenzisayo, amabanga ahlanganisiwe namandla asetshenzisiwe.

1. Ibhendi yefrikhwensi: I-Bluetooth isebenzisa ibhendi engu-2.4GHz, kuyilapho i-433 isebenzisa ibhendi engu-433MHz. I-Bluetooth ine-frequency ephezulu futhi ingaba ngaphansi kokuphazanyiswa okwengeziwe okuvela kuzithiyo zomzimba, kuyilapho i-433 ine-frequency ephansi futhi ukudlulisa kungenzeka ukuthi kungene ezindongeni nasezintweni.

2. Ibanga lokudlulisa: I-Bluetooth inobubanzi obujwayelekile obungamamitha ayi-10, kanti i-433 ingafinyelela emamitha angamakhulu ambalwa. Ngakho-ke i-433 ifanele izimo lapho kudingeka khona ukudluliswa kwebanga elide, njengangaphandle noma ezindaweni zokugcina izimpahla ezinkulu.

3. Ukusetshenziswa kwamandla: I-Bluetooth ngokuvamile isebenzisa ubuchwepheshe be-Bluetooth Low Energy (BLE), obudla amandla amancane uma kuqhathaniswa futhi bufanele amadivayisi asetshenziswa isikhathi eside. I-433 ijwayele ukusebenzisa amandla amancane, kodwa ingaba phezulu kancane kune-Bluetooth.

Sekukonke, i-Bluetooth ilungele izinhlelo zokusebenza zebanga elifushane, ezinamandla aphansi njengamahedisethi, amakhibhodi namagundane. I-433 ilungele izinhlelo zokusebenza ezidinga ububanzi obude nokusetshenziswa kwamandla aphansi, njengokutholwa kwedatha yenzwa, ukulawula okuzenzakalelayo, njll.

Njengoifektri yesithwebuli sochwepheshe,sinikeza izinhlobonhlobo zemikhiqizo yesithwebuli enokuxhumana okuhlukene ukuhlangabezana nezidingo zamakhasimende ahlukene futhi singanikeza izixazululo ezenziwe ngokwezifiso. Ukuze ufunde kabanzi mayelana nemikhiqizo yethu, sicelaXhumana nathi.
