NB-IoT Tsis-magnetic Inductive Metering Module

Lus piav qhia luv luv:

HAC-NBA tsis-magnetic inductive metering module yog PCBA tsim los ntawm peb lub tuam txhab raws li NB-IoT thev naus laus zis ntawm Is Taws Nem ntawm Yam, uas phim cov qauv tsim ntawm Ningshui qhuav peb-inductance dej ntsuas. Nws ua ke NBh cov kev daws teeb meem thiab tsis yog sib nqus inductance, nws yog ib qho kev daws teeb meem rau kev nyeem ntawv meter. Cov kev daws teeb meem suav nrog lub ntsuas ntsuas kev tswj hwm lub platform, qhov ze-kawg tu handset RHU thiab lub davhlau ya nyob twg kev sib txuas lus module. Cov haujlwm suav nrog kev nrhiav tau thiab kev ntsuas, ob txoj kev sib txuas lus NB, kev ceeb toom ceeb toom thiab kev saib xyuas ze-kawg thiab lwm yam, ua kom txaus siab rau cov kev xav tau ntawm cov tuam txhab dej, cov tuam txhab roj av thiab cov tuam txhab hluav taws xob rau kev siv wireless meter nyeem ntawv.

Muaj nuj nqi

No	Muaj nuj nqi	Kev piav qhia
1	Kov khawm	Nws tuaj yeem siv rau kev saib xyuas ze-kawg, thiab tuaj yeem ua rau NB qhia. Nws siv txoj kev kov capacitive, qhov kov rhiab heev.
2	Kev txij nkawm nyob ze	Nws tuaj yeem siv rau ntawm qhov chaw saib xyuas ntawm lub module, nrog rau kev teeb tsa parameter, nyeem cov ntaub ntawv, hloov kho firmware thiab lwm yam. Nws siv txoj kev sib txuas lus infrared, uas tuaj yeem ua haujlwm los ntawm lub khoos phis tawj lossis lub khoos phis tawj PC.
3	NB kev sib txuas lus	Lub module cuam tshuam nrog lub platform los ntawm NB network.
4	Kev ntsuas	Txais cov txheej txheem tsis sib nqus inductance metering, txhawb nqa pem hauv ntej thiab rov qab ntsuas
5	Disassembly tswb	Lub disassembly tswb muaj nuj nqi yog neeg xiam los ntawm lub neej ntawd thaum lub meter module yog powered rau. Tom qab kev teeb tsa thiab 10L metering, lub tswb nrov disassembly yuav muaj. Thaum lub module tawm ntawm lub 'meter' rau li 2s, lub tswb disassembly thiab keeb kwm disassembly tswb yuav tshwm sim thiab ua rau NB qhia. Reinstall lub module thiab lub 'meter' ib txwm ntsuas 10L, lub tswb disassembly yuav tau txais tshem tawm nyob rau hauv 3s, thiab lub disassembly yuav restarted tswb muaj nuj nqi. Lub tswb disassembly keeb kwm yuav raug muab tso tseg tsuas yog tom qab ua tiav nrog kev sib txuas lus module rau 3 zaug.
6	Magnetic nres tswb	Thaum cov hlau nplaum nyob ze rau ntawm Magnetoresistive element ntawm lub ntsuas ntsuas, kev sib nqus nres thiab keeb kwm sib nqus nres yuav tshwm sim. Tom qab tshem tawm cov hlau nplaum, qhov sib nqus nres yuav raug muab tso tseg. Cov keeb kwm sib nqus nres yuav tsuas yog muab tso tseg tom qab cov ntaub ntawv tau tshaj tawm rau lub platform.
