%X 为了提高机场天气雷达系统不间断运行可靠性,本文提出一种双机热备份冗余切换系统,该系统将发射、接收、伺服冗余控制切换集中在一个以国产现场可编程阵列(Field Programmable Gate Array, FPGA)为核心的冗余控制电路板上。主要介绍了冗余系统的总体设计、分机功能。重点研究了冗余控制板的硬件设计、结构设计、FPGA软件设计。该系统已成功应用于国内机场C波段天气雷达,提高了系统的可靠性和可维护性。
In order to improve the uninterrupted operation reliability of airport weather radar system, a redundant switching system with dual thermal backup is proposed. The system concentrates the transmit, receive and servo redundant control switch on a domestic Field Programmable Gate Array (FPGA) as the core of the redundant control circuit board. This paper mainly introduces the overall design and extension function of redundant system. The hardware design, structure design and FPGA software design of redundant control board are mainly studied. The system has been successfully applied to C-band weather radar in domestic airports, which improves the reliability and maintainability of the system.
