Feidhmeanna:

Forbhreathnú Táirge
NB-Tá naisc láidre, clúdach ard, tomhaltas ísealchumhachta, mar shaintréith ag LoT Internet of Things,
and low cost. t is also called the "Narrowband Internet of Things".Because of its very low communication power consumption, the NB-loT wireless remote water meter can continue to work for more than six years without changing the battery. Using the NB-loT wireless remote water meter can realize the wireless automatic meter reading function. At the same time every day, the NB-loT module will collect and automatically transmit the water consumption data of each household to the management platform.Perform statistical analysis and charge for the water consumption of water meters in the managementarea.

The NB-loT system consists of the NB-loT management system platform, base stations, and loT water meters (NB-loT). The system has a high degree of automation, can monitor the operation and consumption of the meter at any time, and has a wide range of applications.

3.Intensive data collection:4 hours from the set start time, one point every 5 minutes, a total of 48 points of accumulated flow.

4.Athphacáistiú sonraí: Nuair nach n-éiríonn le tuairisciú sonraí, déanfar na sonraí a aththuairisciú go huathoibríoch sa chéad tréimhse tuairiscithe eile, agus is féidir sonraí laistigh den raon stórála éifeachtach a-aththuairisciú.

5. Socrú scoite: Déan na pointí ama tuairiscithe a scoite go randamach tríd an gclár, is é 10S an fad measta íosta, agus is é 0 go 8 pointe an réamhshocrú chun a chinntiú nach gcuirfear bac ar an stáisiún bonn cumarsáide mór. méid na sonraí i ghearr ama.

6. Cianshocrú paraiméadair: Tríd an ngléas léitheoireachta infridhearg ríomhaire boise gar do-agus
cumarsáid a dhéanamh leis an ardán bainistíochta, IP, calafoirt agus paraiméadair eile a shocrú

7. Alarm function: When the battery undervoltage is lower than the predetermined value, the platform will automatically alarm to remind the administrator

8. Time proofreading: When the data is reported periodically, the clock will be automatically proofread with the platform to ensure the accuracy of the time
