NB IoT smart meter

Introduction:

Nb iot smart electricity meter refers to the use of local network or Internet and other communication technologies to connect sensors, controllers, machines, people and things together in a new way, forming a network of people and things, things and things, and realizing informatization, remote management control and intelligence. NB IoT smart meters are mainly composed of measurement units, data processing units, communication interface units, ESAM modules, clock modules, etc. It has functions such as electric energy metering, information storage and processing, real-time monitoring, automatic control, information exchange, and load control.

NB IoT Smart Meter Technical Parameters:

Introduction to the advantages of NB IoT smart meters:

(1) Wide coverage: It will provide improved indoor coverage, with NB IoT gaining 20dB more than existing networks in the same frequency band, equivalent to a 100x increase in coverage area capability;

(2) Massive connections: NB IoT can support 100000 connections per sector, with low latency sensitivity, ultra-low device costs, low device power consumption, and optimized network architecture;

(3) Low power consumption: The standby time of NB IoT terminal modules can last up to 10 years;

(4) Low cost: The module cost is very low, and the expected cost of a single consecutive module for the enterprise is no more than $5.

(5) Peak valley function:

a) It has the function of measuring positive and negative active energy.

b) It has a time-sharing metering function, and the active electrical energy is accumulated, stored in total, peak, and off peak according to the corresponding time period

Flat and valley electric energy.

c) Store the total electricity and electricity at various rates for the past 12 months; The data storage boundary time is 24:00 at the end of the month, or the hourly time between the 1st and 28th of each month.
