摘　　要：在分布式电磁资源接入与调度系统中,传统的通信方式无法满足大数据量传输和低时延需求,本文构建了基于国产YX-RFMB反射内存卡的电磁资源高效数据通信网络,将反射内存卡组成的环型结构应用于电磁资源数据传输。通过改变测试数据的大小和测试设备的数量等变量,测量不同参数下的平均时延,同时与TCP(Transmission Control Protocol)传输协议、UDP(User Datagram Protocol)传输协议的平均时延对比分析。结果表明,在256台接入设备时,传输1 kB和1 MB数据量平均时延分别为1.2 ms和38 ms,低于同条件下TCP、UDP的平均时延,表明在电磁资源接入数量和数据传输量大幅提升的情况下,基于反射内存网构建的数据通信网络具有低时延特性,提升了分布式电磁资源接入与调度系统的仿真效率和实时性。Challenges in traditional communication methods for distributed electromagnetic resource access and scheduling systems are addressed.These methods fail to meet the needs for large data volume transmission and low latency.A high-efficiency data communication network for electromagnetic resources,based on the domestic YX-RFMB reflection memory card,was presented as a solution.The network leverages reflection memory technology.The network is configured into a ring structure for the transmission of electromagnetic resource data.Average latency under various parameters are measured by altering the size of test data and the number of test devices.These latencies are then compared and analyzed against those of the TCP and UDP transmission protocols.Results show that with 256 devices connected,average latency for transmitting 1 kB and 1 MB of data are 1.2 ms and 38 ms.The average latency is lower than that of TCP and UDP under similar conditions.The results validate low-latency characteristics of the network.These characteristics are particularly evident when handling a large number of electromagnetic resource connections.The research holds significant importance.It contributes to enhancing the simulation efficiency and real-time performance of distributed electromagnetic resource access and scheduling systems.
