Military UAV, with its low-cost, small size and stealth performance, zero injuries and other advantages, are widely used in various stages of operation. But with expansion of military functions, traditional UAV has been unable to meet the ultra -harsh battlefield conditions, complete multi-task, distributed data processing and high-capacity data transmission requirements, the urgent need for a new, high-performance transport bus based, supports multi-tasking of the UAV equipment. VPX standard as upgrade version of VME, there has been in the field of foreign UAV application. As a new generation of military reinforcement bus products, which meet serial, Gigabit high - speed data rates, support the expansion of the PowerPC architecture and flexible. By analyzing future development of UAV technology-driven trends and related factors, described in detail VPX standard and follow-up OPENVPX standard, and compared with previous versions of the bus, that in the field of UAV system has broad application prospects, and finally gives a UAV-based system model VPX bus.%军用无人机以其低成本高效能、体积小隐身性能强、零伤亡等优势,被广泛应用于作战的各个阶段;但随着军事职能的拓展,传统无人机已无法满足在超恶劣战场环境下,完成多任务、分布式数据处理和大容量数据传输的要求,迫切需要一种新的、基于高性能传输总线的、支持多任务处理的无人机设备；VPX标准作为VME标准的升级版本,在国外无人机领域已有所应用；作为新一代军用加固总线产品,它满足串行、千兆高速数据率,支持PowerPC架构且扩展灵活,以其搭建无人机系统,完全可以满足现在乃至未来的需求；通过对无人机未来发展趋势及相关技术驱动因素分析,详细介绍了VPX及其后续OPENVPX标准,将其与之前版本总线进行比较,认为其在无人机系统各领域具有广泛的应用前景,最后给出一种基于VPX总线的无人机系统模型.
