摘　　要：该文主要对用电采集系统接口通信协议的设计进行深入的探讨。首先介绍采用北斗短消息通信方式发送长数据包时,分组丢失率较大的问题,并根据电力用户用电采集系统的数据特征和通信设备技术要求,提出一种基于ARQ查询命令模式的机制改革,设计出分级式的ARQ机制。该算法在保证一定的通信成功率的前提下,对不同长度的数据包分组进行重新发送,从而提高信道利用率。在协议的设计中,着重讨论分组优先传输,选择定时器的时间,选择重传次数,以及合理的数据传输格式。This paper makes an in-depth discussion on the design of the interface communication protocol of the power acquisition system.Firstly,the problem of high packet loss rate when using Beidou short message communication mode to send long data packets is introduced.According to the data characteristics of power user power acquisition system and the technical requirements of communication equipment,a mechanism reform based on ARQ query command mode is proposed,and a hierarchical ARQ mechanism is designed.On the premise of ensuring a certain communication success rate,the algorithm retransmits packets of different lengths,thus improving the channel utilization.In the design of the protocol,we focus on the packet priority transmission,the selection of timer time,the selection of retransmission times,and the reasonable data transmission format.
