ARMxy BL340 + smart grid distribution automation: ±50m fault location, millisecond response, multi-protocol support. Cuts fault handling time by 40%-60%, reduces outage loss.
Case Details
In the smart grid industry, the reliability and real-time performance of distribution network operation directly affect power supply stability and user experience. Traditional distribution automation systems face core challenges such as scattered data collection, slow fault response, difficult on-site maintenance, and poor protocol compatibility. This solution, based on the
ARMxy BL340 industrial-grade embedded computer with quad-core Cortex-A53 and 4K video decoding capability, builds an intelligent distribution automation system integrating real-time data acquisition, equipment status monitoring, fault rapid location, and remote operation and maintenance. By adopting a multi-source data fusion and fault diagnosis algorithm, it achieves millisecond-level data response and ±50m fault location accuracy. Combined with BLIoTLink, BLRAT, and Node-Red core tools, the solution ultimately shortens fault handling time by 40%-60%, reduces power outage loss by 30%-45%, and realizes full-life-cycle intelligent management of the distribution network.
