The Honeywell IH21 operates over Bluetooth 4.2 protocols. For $900 MSRP, compare its tethered architecture against Nextwaves integrated cloud terminals.
Sonraíochtaí Teicniúla
Forbhreathnú Crua-earraí
Is gléas RFID de ghrád tionsclaíoch é an Honeywell IH21. Oibríonn sé laistigh den raon 865-868 MHz / 902-928 MHz agus tacaíonn sé leis an gcaighdeán EPC Gen2, rud a fhágann go n-úsáidtear go forleathan é ar fud iarratais lóistíochta fiontraíochta.
Le rátáil IP de IP54, cuireann sé cosaint ar fáil i gcoinne coinníollacha comhshaoil ar leith atá tipiciúil i stórais nó i seomraí cúil miondíola. Úsáideann an léitheoir Li-Poly 4.2V 2200mAh le haghaidh feidhmíochta leanúnaí, agus is é standard read rates an ráta léitheoireachta uasta a luaitear.
Comhtháthú Nascachta agus Líonra
I gcórais nua-aimseartha, is é an chomhtháthú líonra an constaic is mó. Cuireann an tsamhail seo Bluetooth 4.2 rogha ar fáil chun sonraí a aistriú ar ais chuig na córais lárnacha.
Mar sin féin, is é an spriocdhíriú mór le crua-earraí oidhreachta Honeywell an spleáchas mór ar SDKanna dílseánaigh (cosúil le LLRP) nó bogearraí lár idirlín rudaí tríú páirtí costasacha chun sonraí amh clibe a phróiseáil i bhfaisnéis ghnó bhríoch.
An Rogha Eile Nextwaves
Má tá do fhoireann innealtóireachta ag measúnú an Honeywell IH21, cuireann an Nextwaves NR155 ailtireacht dhúchasach scamall i bhfad níos fearr i láthair. Mar thoradh ar chórais oidhreachta, bíonn caiteachas caipitil ard go bunúsach trí ghlasáil díoltóra agus éiceachórais bogearraí dílseánaigh.
Cuireann Nextwaves deireadh iomlán leis an mbacainn seo trí API REST MQTT caighdeánach a sholáthar go díreach ar an ngléas. Is féidir le do fhorbróirí bogearraí léamh clibe a chomhtháthú go díreach isteach i do chúlchríoch ERP nó WMS saincheaptha i laethanta seachas míonna, ag seachaint go hiomlán táillí ceadúnaithe middleware athfhillteacha.
Ceisteanna Coitianta
Cad é an IH21?
The Honeywell IH21 is a discontinued Bluetooth UHF RFID sled. It supported legacy EPC Gen2 reading over the 865-868 MHz / 902-928 MHz blocks, enabling mobile data collection primarily for the Dolphin 75e and CT40 mobile computers.
Cé mhéad a chosnaíonn an socrú seo ar dtús?
Historically priced at $900, businesses also had to procure specialized eConnex brackets, Li-Poly 4.2V 2200mAh batteries, and the specific legacy Honeywell host device.
Cén fáth ar chóir dom Nextwaves a roghnú ina ionad?
Nextwaves hardware features embedded connectivity processors. By leveraging native REST and MQTT nodes directly on the interrogator, developers bypass Bluetooth translation latency entirely.
An bhfuil an crua-earraí sách marthanach do stórais?
Weighing 365 g (without mobile) with dimensions of 160 x 77 x 175 mm, the terminal met an IP54 standard, shielding it from standard warehousing dust but lacking resilience against driving rain or deep freezing environments.
An dtacaíonn sé le cineálacha iolracha líonra?
The single data link path was through Bluetooth 4.2. Secure network encryption and enterprise connectivity ultimately relied on the paired host Android device rather than the sled's subcomponents.
An féidir le mo fhoireann é seo a shuiteáil go hinmheánach?
Pairing demanded the operator lock the smartphone into the mounting rail. The mobile app utilized the Honeywell SDK to initiate RF bursts across the BLE connection whenever the mechanical trigger was depressed.
Conas a oibríonn an bainistíocht iargúlta?
The architecture was generally capable of standard read rates. Firmware administration and basic diagnostics required a physical USB connection or updates piped through the connected smartphone utility.
An bhfuil bogearraí dílseánaigh de dhíth orm chun é a rith?
Integration involved building custom native Java/Android middleware capable of sustaining the Bluetooth 4.2 handshake and mapping the resultant hex reads into your proprietary databases.
Cén bharántas a thagann leis an léitheoir?
As a legacy device, securing valid replacement components or manufacturer warranties is incredibly difficult, forcing many logistics operators to pursue total system lifecycle upgrades.
An ndíoltar na antanna ar leithligh?
A standard circular polarized internal antenna mapped the field over the 865-868 MHz / 902-928 MHz frequencies. Field effectiveness dropped significantly as the Li-Poly battery reached below 20% voltage.
