基于FPGA的抗辐照通信与控制系统的设计

Design of Anti-Irradiation Communication and Control System Based on FPGA

伴随着航天事业的飞速发展,航天通信与控制系统对其接口种类和带宽也有着更高要求。由于以太网、1553B(MIL-STD-1553B)等通信总线具有高带宽、接口专用等特点,常规处理器难以在航天控制系统中广泛应用。现场可编程门阵列(Field Programmable Gate Array,FPGA)具有硬件可编程、知识产权核(Intellectual Property Core,IP)可灵活选择、通用接口数量多等优点,在航天通信与控制系统中具有较大的应用前景。此文设计了一种基于FPGA的抗辐照通信与控制系统,该系统全部采用抗辐照元器件,具备以太网、1553B等多种通信总线模块。测试结果表明,该系统能够满足航天环境中多种类、高带宽与高可靠的通信要求。

With the rapid development of the aerospace industry, aerospace communication and control systems also have higher requirements for these interface types and bandwidth. Due to the characteristics of the Ethernet,1553 B(MIL-STD-1553 B), and other communication buses with high bandwidth and unique interfaces, it is difficult for conventional processors to be widely used in aerospace control. Field-programmable gate array(FPGA) has the advantages of programmable hardware, flexible selection of intel ectual property core(IP core),and many available interfaces. Therefore, it has a great application prospect in aerospace communication and control systems. This paper designs an anti-irradiation communication and control system based on FPGA.The plan all adopt anti-irradiation components and has a variety of communication buses such as Ethernet and 1553 B. The test results show that the system can meet the communication requirements of multiple types,high bandwidth, and high reliability in the aerospace environment.
