AI Technical Summary

Technical Problem

In the scenario of distribution network collaboration between pole-mounted circuit breaker (FTU) and ring main unit (DTU), the existing communication protocol is difficult to effectively optimize the ordering of data packets in the DTU's transmission buffer queue, and cannot take into account the different transmission needs of local data packets and forwarded data packets, resulting in unreasonable data transmission and reduced reliability.

Method used

By obtaining data packets in the sending buffer queue, determining the ratio of non-forwarded data packets to forwarded data packets, and employing an enhanced scheduling and sorting method, a sending window is constructed. Based on the remaining time limit, freshness, closed-loop correlation, fair compensation value, and whether it is a forwarded data packet, the data packets are reordered and sent.

Benefits of technology

It improves the rationality and reliability of data transmission, adapts to mixed business scenarios, takes into account both timeliness and closed-loop business needs, and enhances the fairness of data transmission.

Abstract

The application discloses a distribution network cooperative networking device fusing a pole-mounted circuit breaker FTU and a ring network box DTU, and the device comprises a memory and a processor, and the memory and the processor are configured to perform the following operations: obtaining a data packet to be sent; judging whether the proportion of non-forwarding data packets and forwarding data packets is less than a proportion threshold; if yes, performing enhanced scheduling sorting on a sending cache queue, and the enhanced scheduling sorting comprises: selecting data packets from the sending cache queue to construct a sending window according to a preset window entry quota; and for the data packets entering the sending window, reordering the data packets in the sending window based on the remaining time limit, the freshness, the closed-loop correlation, the fair compensation value and whether the data packet is a forwarding data packet of each data packet. The application can improve the adaptability of the sending order to a mixed service scenario, and takes into account the timeliness, the closed-loop service demand and the sending fairness, thereby improving the rationality and reliability of data uploading.
