针对航天发射场智能化快速测发的建设需求,提出了一种应用第五代移动通信技术进行无线测发网络建设的方案,主要解决发射场箭地无线通信覆盖及与公共5G移动通信网的便捷融合,可满足测试数据不小于100Mbps的传输速率,测发指令传输时延小于2ms,传输可靠性小于10^-6,同时支持远程测发及便携式测发的潜在应用需求。无线测发网络采用接入网+承载网+核心网的架构,打造5G-SA独立组网模式的工业现场无线总线,接入网用于航天发射场前后端的无线信号覆盖,承载网及核心网实现数据传输及网络管理,采用网络切片的形式将大带宽传输及测发指令传输的应用需求结合起来。提出了应用无线测发网进行无线测发应用的方案,并开展了性能分析。

A wireless vehicle test and launch control system based on 5G technology

In response to the need for the construction of intelligent fast space test and launch control system(TLCS) for aerospace launch sites, this paper proposes a solution of using the 5G mobile communication technology to build a wireless-TLCS network, which mainly solves the wireless communication coverage between the launch vehicle and ground, and fusion to the public 5G mobile communication network as well. The wireless-TLCS network plays a role as industrial field wireless bus of 5G-SA independent networking mode, which can provide more than 100Mbps high-speed transmission of test data and high-reliability(<10^-6), low-latency(<3ms) transmission of launch control instructions by using the network slice; meanwhile, it can support the potential application of portable TLCS and remote TLCS. The network adopts the architecture as access bearer core, which the access network is used for wireless signal coverage between the front and back ends, bearer network and core network realizes data transmission and network management. This paper also proposes the application of wireless test and launch control system and analyses its performance.
