In the power and environmental monitoring systems of communication access rooms, base stations, and data centers, the Field Supervision Unit (FSU) serves as the "nerve ending" connecting physical devices to the monitoring center. For a long time, the industry has commonly adopted a "combination model" to build FSUs: one industrial controller responsible for data acquisition and protocol conversion, one independent PLC for logic control, and one industrial switch or router for network transmission. Although this "three-device stacking" solution works functionally, it exposes sharp contradictions in operation and maintenance.
Traditional solutions separate the three major functions of acquisition, control, and communication. This not only results in high hardware procurement costs but also means more connecting cables, power adapters, and physical space occupation due to multiple devices. Each additional device adds a potential point of failure and increases the complexity of spare parts management.
Access rooms contain numerous equipment brands, and devices such as smart air conditioners, UPS, battery banks, and access control systems use different communication protocols. In traditional solutions, the collector, PLC, and router come from different manufacturers, and protocol parsing often relies on separate software environments. Any new device or protocol change requires coordination among multiple R&D teams, with deployment cycles measured in months, frequently accompanied by issues like data inconsistency and missing alarms. More troublesome is that the operating interfaces and debugging logic of FSU devices from different manufacturers vary greatly. Front-line maintenance personnel must memorize multiple debugging techniques, making it difficult for provincial and municipal supervision centers to manage and maintain them uniformly.
Traditional FSU solutions feature deep software-hardware coupling. When the B-interface specification upgrades or new functional requirements emerge, progress is often constrained by the original equipment manufacturer's technical capabilities and willingness to cooperate. Once a manufacturer ceases maintenance for old models or exits the market, a large number of existing FSUs face the dilemma of being unable to upgrade or even being scrapped, resulting in serious investment waste.
In response to these longstanding industry issues, Jinan USR IOT Technology has launched the USR-EG628 industrial PC. By integrating four core capabilities—"Edge Computing + AI Computing Power + Communication Routing + PLC Control"—into a single device, it offers a cost-effective game-changing solution. With the comprehensive performance of one device, it replaces the traditional combination of "Controller + PLC + Router," opening a new path for the construction and renovation of access room FSUs.
Core Advantage 1: Highly Integrated Functions, 38% Reduction in Hardware Costs.The USR-EG628 industrial PC is based on an ARM architecture quad-core 64-bit processor with a clock speed of up to 2.0GHz. It features a built-in NPU with 1.0 TOPS computing power, equipped with 4GB DDR4 memory and 32GB eMMC storage. It natively supports over a hundred industrial protocols including Modbus, OPC UA, IEC104, and DL/T645, while also incorporating an OpenPLC programming environment (compliant with IEC61131-3 standards) and the WukongEdge edge computing platform. A single EG628 can simultaneously handle data acquisition, logic control, protocol conversion, and 4G/dual-band WiFi/Ethernet multi-network backup routing functions. Calculations show that for the same number of monitoring points, replacing the traditional three-device combination with the EG628 can reduce hardware procurement and installation costs by 38%.
Core Advantage 2: Breaking Protocol Silos, Enabling "Plug-and-Play" Operations.The WukongEdge platform built into the EG628 industrial PC comes pre-configured with rich protocol templates and local configuration tools, supporting visual local setup via an HDMI-connected screen. It supports Lua scripting and Docker containerized deployment, flexibly accommodating non-standard protocol customization needs. This feature perfectly aligns with the "white-box" trend in FSU promoted by telecom operators—by unifying software and hardware interface standards, it enables remote downloading of protocol libraries and automatic parameter adaptation, significantly simplifying the commissioning process and reducing deep dependence on manufacturers.
Core Advantage 3: Industrial-Grade Quality and Remote Intelligent Control, Adapting to Harsh Environments.Access room environments are complex, with high temperatures, dust, and electromagnetic interference being common. The EG628 industrial PC adopts a fanless passive cooling design, supports a wide operating temperature range of -20°C to 70°C, features three-level surge and electrostatic protection, and includes a built-in system watchdog to ensure stable 7×24 operation under harsh conditions. Additionally, it supports remote deployment, firmware upgrades, and centralized operation and maintenance management through platforms like USR Cloud and Alibaba Cloud, effectively solving management difficulties caused by device dispersion.
At a time when the communications industry is vigorously promoting cost reduction, efficiency enhancement, and digital operations, the selection of access room FSUs should no longer be a simple function stacking exercise. Through its "four-in-one" high integration, the USR-EG628 industrial PC not only reduces hardware costs at the source, but also directly addresses the three core pain points of traditional FSU solutions—deep protocol barriers, inefficient commissioning, and difficult upgrades/reuse—with its powerful edge computing capabilities, open software ecosystem, and industrial-grade reliability. For access room scenarios pursuing high cost-performance and sustainable operations, the USR-EG628 industrial PC undoubtedly provides an ideal choice that balances immediate cost advantages with future evolutionary flexibility.
The USR-EG628 is an ARM architecture industrial PC that integrates edge computing, PLC control, local configuration, and diverse communication capabilities, specifically designed for industrial IoT and room monitoring applications. It features an industrial-grade quad-core 64-bit processor with 1.0 TOPS NPU computing power, supports 4G/dual-band WiFi/Ethernet multi-network backup, and offers rich interfaces (2×RS485, 1×CAN, 2×Ethernet ports, USB, HDMI). It has obtained multiple authoritative certifications including RCM, 3C, ANATEL, CE, FCC, MTC, NBTC, ROHS, WEEE, and Cybersecurity, ensuring reliable quality.
