LoRaWAN single and three-phase smart meter communication module to Realize independent installation of meter
1. TW LoRaWAN single and three-phase communication module is based on edge computing. It is an independent installation
of single and three-phase smart meters. The electrical interface is unified, which avoids the secondary development of
LoRaWAN wireless communication module of electric energy meter.
2. LoRaWAN meter communication module is embedded with LoRaWAN node module with secure encryption transmission
function and high-speed 32-bit microprocessor. It can effectively control the communication module and automatically acquire
various data of the electric energy meter according to its internal upload cycle, reporting task and other operating parameters.
And the data of the electricity meter can be uploaded to the cloud platform on a regular basis.
- Main functions and features
1. Built-in MCU. Edge computing capability;
2. 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;
3. 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;
4. Professional interface data flow automatic control technology. Give priority to the instruction frame issued by the platform gateway
to complete real-time two-way transparent transmission;
5. The standard smart meter communication interface and module box design of the State Grid shall be adopted. Suitable for most
smart meters. It can be replaced directly.
6. The configured parameters can be saved when the module is powered down. Automatic recovery when power is restored.
7. Independent power conversion circuit and power enable control circuit. Effectively use DC12V power supply of module interface
and I/O control output of ammeter.
