Smart LoRaWAN Modules for Three Phase Electric Meters Reading System
RDK-LoRaWAN three-phase communication module is a LoRaWAN wireless communication module which is based on edge calculation. It embeds the LoRaWAN node-module and the high-speed 32-bit microprocessor with secure encrypted transmission. 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. It realizes independent installation of single and three-phase smart meters, unified electrical interface and avoids secondary development of electric energy meter.

Features and Functions:
1. MCU with edge calculation ability will Built-in in the smart
electric meter.
2. The LoRaWAN wireless remote mode will configure the operating
parameters of the communication module, automatically perform the
task list and upload frequency required for the active upload task,
etc.
3. 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.
4. Professional interface data flow to automatic control
technology, prioritize processing of instruction frames sent by
platform gateways, and complete real-time bidirectional transparent
transmission.
5. 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).
6. The configured parameters can be saved when the module is
powered down and automatically restored when power is restored.
7. 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.
