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.

- 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.
