Transmission and Distribution Visualization Gateway

The transmission and distribution visualization gateway is an edge‑intelligence gateway application developed based on NB2, designed for grid‑related and other industrial‑grade edge‑intelligence scenarios. It primarily focuses on monitoring complex areas of the transmission network, enabling local sensing and identification of transmission line conditions as well as special events such as wildfires, ice accretion, foreign objects, and tower cranes, while also interacting with the central master station. Built on the NB2 stamp‑hole core board and complemented by an expansion baseboard, the gateway forms a power‑industry edge‑intelligence platform that supports data aggregation, processing, reporting, and interactive communication—particularly offering capabilities like image acquisition, AI‑based edge computing, and real‑time data backhaul. The gateway also meets IP67 protection standards, making it suitable for demanding outdoor industrial environments.

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.

Low-Carbon Integrated Energy Management

The low‑carbon integrated energy management solution is centered on the NB2 chip, integrating edge‑side carbon terminals and carbon metering devices. Leveraging blockchain technology, it enables carbon‑trade traceability, data notarization, and credit rating, thereby achieving comprehensive monitoring and optimized planning of carbon emissions. It offers enterprises services such as carbon‑footprint tracking, carbon certification, and carbon‑finance solutions, helping them meet their low‑carbon goals. The solution is applicable to corporate carbon‑emission management, energy‑efficiency optimization, and environmental‑consulting applications.

Digital Warehouse Management for IT Equipment

The digital shelf system, built on AIoT and WMS, uses the NB2 chip as its main controller. It collects device operating status via inventory‑monitoring sensors and identifies key touchpoints in inventory‑related operations, thereby enhancing overall inventory management efficiency. Additionally, it enables integrated multi‑process workflows, effectively safeguarding both inventory items and logistics processes. This solution is primarily deployed across various warehousing and logistics settings, including e‑commerce warehouses, large logistics centers, and retail distribution facilities.
