Smart Industrial Gateway

The industrial gateway is an edge‑computing device developed based on the YF Technology NB2L core board. It is designed for a wide range of industrial‑grade edge‑computing applications and integrates numerous industrial‑grade interfaces and resources, including RS‑485, RS‑232, Ethernet, USB, CAN, digital I/O, HDMI, and TF card slots. Optional wireless communication modules—such as Wi‑Fi, Bluetooth, and 4G/5G—are available to meet specific requirements. On the software side, the industrial gateway runs the Linux operating system and supports standard middleware like Docker, enabling convenient application development and deployment.

New Power System Integrating Source, Grid, Load, and Storage

The next-generation power system’s source‑grid‑load‑storage solution is centered on NB2‑series chips and employs AI‑optimized control algorithms. Leveraging a highly flexible platform, it integrates distributed energy resources such as photovoltaic, wind, and hydropower, along with energy storage assets, enabling comprehensive sensing and coordinated control of generation, load, and storage. The system supports applications like peak‑shaving and valley‑filling, demand response, and power‑quality optimization, meeting diverse electricity‑demand requirements and serving scenarios such as distributed‑resource management, smart grid regulation, and energy‑system optimization.
