Texnik xususiyatlari
Uskunaga umumiy nuqtai nazar
Honeywell IH21 - bu sanoat darajasidagi RFID qurilmasi. U 865-868 MHz / 902-928 MHz diapazonida ishlaydi va EPC Gen2 standartini qo'llab-quvvatlaydi, bu esa uni korxona logistika ilovalarida keng qo'llanilishini ta'minlaydi.
IP54 IP reytingi bilan u omborlar yoki chakana savdo do'konlarida odatiy bo'lgan ma'lum ekologik sharoitlardan himoya qiladi. O'quvchi uzluksiz ishlash uchun Li-Poly 4.2V 2200mAh dan foydalanadi, uning maksimal o'qish tezligi standard read rates ga yetadi.
Ulanish va tarmoq integratsiyasi
Zamonaviy joylashtirishlarda tarmoq integratsiyasi eng muhim to'siq hisoblanadi. Ushbu model ma'lumotlarni markaziy tizimlarga o'tkazish uchun Bluetooth 4.2 variantlarini taklif etadi.
Biroq, eski Honeywell uskunalari bilan bog'liq asosiy muammo shundaki, xom teg ma'lumotlarini mazmunli biznes ma'lumotlariga aylantirish uchun xususiy SDK-larga (masalan, LLRP) yoki qimmat uchinchi tomon IoT middleware-ga katta bog'liqlik mavjud.
Nextwaves Alternativi
Agar sizning muhandislik jamoangiz Honeywell IH21 ni baholayotgan bo'lsa, Nextwaves NR155 bulutga asoslangan arxitekturani taqdim etadi. Eski tizimlar sotuvchiga bog'liqlik va xususiy dasturiy ta'minot ekotizimlari orqali yuqori kapital xarajatlarni keltirib chiqaradi.
Nextwaves qurilmada to'g'ridan-to'g'ri standart MQTT REST API ni taqdim etish orqali bu to'siqni butunlay yo'q qiladi. Sizning dasturiy ta'minot ishlab chiquvchilaringiz teglarni o'qishni o'z ERP yoki WMS backendga oylarda emas, balki kunlarda integratsiya qilishlari mumkin, bu esa takroriy vositachi litsenziyalash to'lovlarini butunlay chetlab o'tadi.
Ko'p so'raladigan savollar
IH21 nima?
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.
Ushbu sozlashning boshlang'ich narxi qancha?
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.
Nima uchun men Nextwavesni tanlashim kerak?
Nextwaves hardware features embedded connectivity processors. By leveraging native REST and MQTT nodes directly on the interrogator, developers bypass Bluetooth translation latency entirely.
Uskuna omborlar uchun yetarlicha bardoshlimi?
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.
U bir nechta tarmoq turlarini qo'llab-quvvatlaydimi?
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.
Mening jamoam buni ichki o'rnatishi mumkinmi?
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.
Masofadan boshqarish qanday ishlaydi?
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.
Uni ishlatish uchun xususiy dasturiy ta'minot kerakmi?
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.
O'quvchi bilan qanday kafolat keladi?
As a legacy device, securing valid replacement components or manufacturer warranties is incredibly difficult, forcing many logistics operators to pursue total system lifecycle upgrades.
Antennalar alohida sotiladimi?
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.
