RDK-LoRaWAN Communication Module for Wireless Control Smart Electric Meter

RDK-LoRaWAN single-phase and three-phase communication module is a LoRaWAN wireless communication module which is based on edge calculation. It realizes independent installation of single and three-phase smart meters, unified electrical interface and avoids secondary development of electric energy meter.

This module embeds the LoRaWAN node-module and the high-speed 32-bit microprocessor with secure encrypted transmission. It can control the communication module effectively and acquire the various data of the electric energy meter automatically according to the internal uploading period and the running parameters of the reporting task, and realize upload the data of electric meters timely to the cloud platform. The module can directly replace the PLC module or the current small wireless module of the electric energy meter, and realize the security control function of adding/decrypting data of the LoRaWAN network terminals, gateway authentication, and multi-node synchronization anti-collision.

Specification:

• Features and Functions
  • Built-in MCU with edge calculation ability.
  • The communication module automatically obtains the unique communication address information of the currently installed smart meter after power-on, and binds with its own remote communication address.
  • The LoRaWAN wireless remote mode can flexibly configure the operating parameters of the communication module, such as automatically perform the task list and upload frequency required for the active upload task, etc.
  • Professional interface data flow to automatic control technology, prioritize processing of instruction frames sent by platform gateways, and complete real-time bidirectional transparent transmission.
  • It adopts the standard national grid smart meter communication interface and module box design, which is suitable for most smart meters and can be directly replaced (hot plugged).
  • The configured parameters can be saved when the module is powered down and automatically restored when power is restored.
  • Independent power conversion circuit and power enable control circuit, effectively utilize the DC12V power supply of the module interface and the I/O control output of the meter.
