NB IoT single-phase smart meter

Product Details

Product Details

Introduction:


NB IoT single-phase smart meters rely on China Telecom's 800M IoT private network, combined with the advantages of NB IoT technology such as wide coverage, low power, large connection, and low cost, to achieve IoT terminal access and data transmission through NB IoT cards. The battery life can reach several years or even ten years, while also providing very comprehensive indoor cellular data connection coverage. The system also has the functions of electricity metering and monitoring, and can know the operating status of the electricity meter without entering the household.

NB IoT single-phase smart meter function detailed introduction:


1、 Data saving function: The smart energy meter based on NB-IOT not only complies with the State Grid's smart energy meter specifications, but also interfaces with third-party platforms. All data is ultimately stored in the database through communication providers (such as China Mobile, China Telecom, and China Unicom) base stations. Finally, the platform conducts statistical analysis on the data and objectively and clearly displays it on the power online service system platform.


2、 Remote communication function: The electric energy meter is equipped with an NB-IOT communication module, which allows basic settings and operations of the meter through the platform. The platform itself has permission authentication, which can be operated by customers with different identities,


3、 Remote cost control function: The electricity meter itself does not display electricity and electricity related information, and all data is uploaded to the server. According to the electricity standards of State Grid Corporation of China, the final calculation is completed by the online power service system. In addition, the system platform also provides permission settings for users, property management, etc. to perform remote command operations, such as opening, closing, meter reading, etc.


4、 Clock time period and rate function: This energy meter can be programmed with two sets of rate time period tables built-in, and automatically converted at the corresponding time. Each time period supports 4 rates. They are respectively sharp, peak, flat, and valley. This energy meter also has a high-precision real-time clock with real-time temperature compensation, which can ensure that the real-time clock error is less than 2 minutes within a year in natural environments.
