Product Overview
TW LoRaWAN single and three-phase communication module based on edge computing is a single and three-phase smart meter that can be installed independently. The electrical interface is unified, which avoids the secondary development of LoRaWAN wireless communication module of electric energy meter.
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 operation parameters of the communication module according to its internal upload cycle and reporting tasks. Automatically acquire various data of the electric energy meter, and realize the data of the electric energy meter to be actively uploaded to the cloud platform on a regular basis. The communication module can directly replace the PLC module or small wireless module of the current electricity meter. It can realize security control functions such as encryption/decryption of data at the wireless end of the LoRaWAN network, gateway authentication and network access, multi-node synchronization and anti-collision.
Main Features
- Built-in MCU. Edge computing capability;
- 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 to complete real-time two-way transparent transmission;
- 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 (hot plug).
- The configured parameters can be saved when the module is powered down. Automatic recovery when power is restored.
- Independent power conversion circuit and power enable control circuit. Effectively use DC12V power supply of module interface and I/O control output of ammeter.
