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

Izikena zebhakhowudi ezingenazingcingo ngoku ezikwimarike zisebenzisa obu buchwepheshe bulandelayo bonxibelelwano

Uqhagamshelo lweBluetooth:

Ukuqhagamshelwa kweBluetooth yindlela eqhelekileyo yokudibanisaiiskena ezingenazingcingo. Isebenzisa iteknoloji yeBluetooth ukuqhagamshela ngaphandle kwamacingo iskena kwisixhobo. Unxibelelwano lweBluetooth luphawulwa kukuguquguquka kwayo kuzo zonke izixhobo zeBluetooth, ukuhambelana okuphezulu, umgama wothumelo oluphakathi kunye nokusetyenziswa kwamandla okuphakathi.

2.4G uqhagamshelwano:

Uqhagamshelo lwe-2.4G yindlela yoqhagamshelwano engenazingcingo usebenzisa i-2.4G ye-wireless band. Inoluhlu olude kunye nesantya esiphezulu sothumelo, okwenza ukuba lulungele izicelo ezinemigama emide okanye apho kufuneka amazinga aphezulu othumelo. Uqhagamshelo lwe-2.4G ngokuqhelekileyo lusebenzisa umamkeli we-USB ukubhanqa nesixhobo, ekufuneka siqhagamshelwe kwizibuko le-USB lesixhobo.

433 uqhagamshelwano:

Uqhagamshelo lwe-433 yindlela yoqhagamshelwano engenazingcingo esebenzisa ibhendi yerediyo ye-433MHz. Inoluhlu olude lokuhambisa kunye nokusetyenziswa kwamandla aphantsi, okwenza ukuba ilungele izicelo ezifuna ukuhanjiswa komgama omde kunye nokusetyenziswa kwamandla aphantsi. Uqhagamshelo lwe-433 ludla ngokudityaniswa nesamkeli se-USB esifuna ukuqhagamshelwa kwizibuko le-USB lesixhobo.

Kubalulekile ukukhetha uxhulumaniso olufanelekileyo kwiimfuno ezithile. Kwimigama emifutshane kunye neemfuno zamandla asezantsi, khetha uqhagamshelo lweBluetooth; kwimigama emide kunye namazinga aphezulu edatha, khetha uxhulumaniso lwe-2.4G; kwimigama emide kunye neemfuno zamandla asezantsi, khetha uqhagamshelo lwe-433. Izinto ezinjengokuhambelana kwesixhobo, iindleko kunye nobunzima bokulondolozwa kufuneka kuqwalaselwe.

Ukuba unomdla okanye umbuzo ngexesha lokukhetha okanye ukusetyenziswa kwaso nasiphi na iskena sebhakhowudi, nceda Cofa ikhonkco elingezantsi thumela umbuzo wakho kwiposi yethu esemthethweni.(admin@minj.cn)ngqo!MINJCODE uzibophelele kuphando kunye nophuhliso lwetekhnoloji yesikena sebhakhowudi kunye nezixhobo zokusebenza, inkampani yethu ineminyaka eli-14 yamava oshishino kwiinkalo zobungcali, kwaye yamkelwa kakhulu luninzi lwabathengi!

Umahluko phakathi kwe-2.4G kunye neBluetooth:

I-teknoloji ye-wireless ye-2.4GHz iteknoloji yokudlulisa i-wireless ye-short-range, kunye nokuhanjiswa kweendlela ezimbini, ukuchasana okunamandla, umgama omde wokuhambisa (uluhlu olufutshane lwe-wireless technology), ukusetyenziswa kwamandla aphantsi, njl. I-2.4G iteknoloji inokuqhagamshelwa ngaphakathi kwe-10 iimitha. kwikhompyuter.

Itekhnoloji yeBluetooth yiprotocol yothumelo engenazingcingo esekwe kwitekhnoloji ye-2.4G. Iyahluka kobunye ubugcisa be-2.4G ngenxa yendlela eyahlukileyo esetyenziswayo kwaye ibizwa ngokuba yi-Bluetooth technology.

Ngapha koko, iBluetooth kunye ne-2.4G itekhnoloji engenazingcingo ngamagama amabini ahlukeneyo. Nangona kunjalo, akukho mahluko phakathi kwezi zimbini ngokwemiqathango yokuphindaphinda, zombini zikwibhendi ye-2.4G. Qaphela ukuba ibhendi ye-2.4G ayithethi ukuba yi-2.4G. Enyanisweni, umgangatho weBluetooth ukwiibhendi ze-2.402-2.480G. Iimveliso ze-2.4G kufuneka zixhotyiswe nge-receiver. Iimpuku zanamhlanje ze-2.4G ezingenazingcingo ziza kunye nomamkeli; Iimpuku zeBluetooth azifuni umamkeli kwaye zinokuqhagamshelwa kuyo nayiphi na imveliso eyenziwe ngeBluetooth. Okona kubaluleke kakhulu, umamkeli kwi-2.4G yemouse engenazintambo inokusebenza kuphela kwimodi enye ukuya kwelinye, ngelixa imodyuli yeBluetooth inokusebenza kwindlela enye ukuya kwabaninzi. Iingenelo ziza nezinto ezingeloncedo. Iimveliso ezisebenzisa iteknoloji ye-2.4G zikhawuleza ukudibanisa, ngelixa iimveliso ezisebenzisa iteknoloji yeBluetooth zifuna ukubhanqa, kodwa iimveliso zeteknoloji ye-2.4G nazo zifuna i-port ye-USB, phakathi kwezinye izinto eziluncedo kunye nokungonakali. Okwangoku, iimveliso eziphambili ezisebenzisa itekhnoloji yeBluetooth zii-headsets zeBluetooth kunye nezithethi zeBluetooth. Iimveliso zeteknoloji ye-2.4G ubukhulu becala ziikhibhodi neempuku ezingenazingcingo.

Umahluko phakathi kweBluetooth kunye ne433:

Iiyantlukwano eziphambili phakathi kweBluetooth kunye ne-433 ngamaqela onomathotholo abawasebenzisayo, imigama ehlanganisiweyo kunye namandla asetyenzisiweyo.

1. Ibhendi yokuphindaphinda: I-Bluetooth isebenzisa ibhendi ye-2.4GHz, ngelixa i-433 isebenzisa ibhendi ye-433MHz. I-Bluetooth ine-frequency ephezulu kwaye ingaba phantsi kokuphazamiseka okungaphezulu kwimiqobo yomzimba, kanti i-433 ine-frequency ephantsi kunye nokuhanjiswa kunokwenzeka ukuba kungene kwiindonga kunye nezinto.

2. Umgama wothumelo: IBluetooth inoluhlu oluqhelekileyo lweemitha ezili-10, kanti i-433 inokufikelela kumakhulu aliqela eemitha. I-433 ke ngoko ifanelekile kwiimeko apho kufuneka ukuhanjiswa koluhlu olude, njengangaphandle okanye kwiindawo zokugcina iimpahla.

3. Ukusetyenziswa kwamandla: IBluetooth isebenzisa iteknoloji yeBluetooth Low Energy (BLE), edla amandla amancinci kwaye ifanele izixhobo ezisetyenziswa ixesha elide. I-433 ikwathande ukusebenzisa amandla amancinci, kodwa inokuba phezulu kancinci kuneBluetooth.

Ngokubanzi, iBluetooth ifanelekile kuluhlu olufutshane, usetyenziso lwamandla aphantsi njengee-headsets, iikhibhodi kunye neempuku. I-433 ifanelekile kwizicelo ezifuna uluhlu olude kunye nokusetyenziswa kwamandla aphantsi, njengokufumana idatha yenzwa, ulawulo oluzenzekelayo, njl.

Njengeumzi-mveliso wescanner wobuchwephesha,sinikezela ngoluhlu olubanzi lweemveliso zeskena kunye nokudibanisa okuhlukeneyo ukuhlangabezana neemfuno zabathengi abahlukeneyo kwaye kunokubonelela ngezisombululo ezilungiselelwe. Ukuze ufunde ngakumbi malunga neemveliso zethu, ncedaQhagamshelana nathi.
