NBIoT Wireless Communication Module Built-in MCU with Automatic Edge Computing Capability

Product Overview

NB-IoT smart meter communication module is embedded with high-performance, low-power, multi-band NB-IoT wireless communication module and low-power 32-bit microprocessor. As long as the use environment of smart electricity meters is within the coverage of NB-IoT communication network, it can realize the instant access of electricity meters to the management platform, receive and respond to the reading/control instructions issued by the platform. At the same time, it can effectively control the upload cycle and reporting tasks and other operating parameters within the communication module. Automatically acquire various data of the electricity meter and upload it to the cloud platform on a regular basis.

Main functions and features

The communication module has the ability to automatically obtain the unique communication address information of the currently equipped smart meter after power-on. And realize binding with its own remote communication address;
LoRaWAN wireless remote mode can flexibly configure the operation parameters such as task list and upload cycle time required by the communication module to automatically execute the active upload task;
Professional interface data flow automatic control technology. Give priority to the instruction frame issued by the platform gateway. Complete real-time two-way transparent transmission;
The standard smart meter communication interface and module box design of the State Grid shall be adopted. It is suitable for most smart meters and can be replaced directly.
