Abstract: Aiming at the industry pain points in the current distribution and power consumption system, such as hardware resource waste, cross-terminal data interaction barriers, and high full-life-cycle operation and maintenance costs caused by the independent deployment of distribution terminals and marketing terminals, an intelligent fusion terminal design scheme based on the “4+1” multi-core heterogeneous chip is proposed. The terminal adopts a heterogeneous architecture consisting of an ARM quad-core processor and an independent MCU core. The ARM quad-core processor runs the Linux operating system to undertake non-real-time tasks including high-precision marketing data collection and complex edge-side data analysis, while the MCU core operates the RTOS real-time system to meet millisecond-level real-time requirements such as distribution remote signal response and AC sampling calculation, thereby realizing the deep integration of distribution monitoring and marketing service functions. Verified by laboratory tests and pilot operation in simulated transformer districts, the terminal achieves excellent performance: the measured delay of distribution remote signal response meet the requirement of ≤5 ms, the error of marketing power consumption data collection is controlled within ±0.2%, and the edge computing task processing efficiency is 42% higher than that of traditional split-type terminals. This scheme effectively solves the coordination problem between “real-time performance and complexity” of distribution and power consumption terminals, providing an engineering feasible solution for the integrated upgrading of distribution and power consumption information collection systems.
