On June 15, 2026, FEXLINK officially released the V2.0 firmware for the Electrical Safety Monitoring Terminal. This upgrade addresses the increasingly complex distribution node monitoring needs in medium-to-large plants and integrated energy scenarios, achieving key capability leaps simultaneously in three core areas: data acquisition, edge computing, and communication links. The V2.0 firmware has passed FEXLINK's internal full-scenario regression testing and field trial validation across 200+ customer sites. Starting today, it will be rolled out in batches to all online devices via gray release, and customers can complete OTA upgrades with one click through the FEXLINK Cloud platform or local O&M tools.

At the data acquisition level, the V2.0 firmware introduces 8-channel RS485 concurrent acquisition for the first time, simultaneously supporting smart lightning protection SPD monitoring modules, leakage monitoring modules, temperature monitoring modules, arc monitoring modules, smart circuit breakers, three-phase imbalance control modules, power quality analyzers, and DIN-rail meters — covering 100% more distribution nodes per device than V1. Combined with the existing 260+ electrical parameter real-time acquisition, 1μS-level transient waveform capture, and 10μA-level leakage monitoring accuracy, the V2.0 firmware supports full-dimension sensing of plant-level panoramic distribution topology, providing a high-quality data foundation for the subsequent 27-sub-model electrical safety diagnosis and 408 national standard rule engine.

At the edge computing level, the V2.0 firmware introduces an NPU-accelerated edge AI inference engine, offloading the high-real-time subset of the original 60+ cloud algorithm models to run locally on the terminal. The end-to-end response latency for typical electrical fire early warning scenarios is compressed from the original 3-second level to under 800 milliseconds, while the local inference accuracy for multi-dimensional fault diagnosis is maintained above 99.2%. Additionally, the firmware adds circular storage for 100,000 local event data entries and offline data resumption capability — in scenarios where the 4G link is abnormal or the cloud is unreachable, the device can continue operating and automatically backfill data, ensuring zero loss of critical alarm data and significantly improving the industrial site's resilience against network interruptions.

At the communication link level, the V2.0 firmware adds 4G dual-SIM dual-link redundancy with automatic switching. The primary-backup link heartbeat interval can be configured from 5 to 30 seconds, with link switching latency under 2 seconds, effectively handling connection interruptions caused by single-operator network fluctuations or base station handovers. Combined with the FG smart gateway's WiFi/wired network backhaul capability, the device can flexibly build communication combinations such as "4G primary + 4G backup," "4G + wired," and "4G + WiFi," adapting to application scenarios with extremely high communication reliability requirements such as the Shenzhen-Zhongshan Link, Yangjiang offshore wind power, petrochemical oil tank farms, and rail transit.

Performance test results show that under a typical 8-channel concurrent scenario, the V2.0 firmware's overall data throughput increased by 40% compared to the V1 version, average CPU utilization dropped by 18%, and device MTBF (Mean Time Between Failures) increased to over 80,000 hours. FEXLINK will continue to position itself as "a company that produces data," deepening its terminal sensing and edge intelligence capabilities around the SLCIE Capability Model, working with industrial customers to promote the scaled deployment of Digital Energy IoT in industrial carbon reduction, electrical safety, and energy efficiency management scenarios.
