双曲线一号运载火箭综合电子系统的设计与实现

Design and Implementation of Integrated Modular Avionics for Hyperbola-1 Launch Vehicle

针对民营商业运载火箭“双曲线一号”高可靠、低成本、快响应的要求,设计了一种自定义高速串行总线架构的高集成度箭载综合电子系统.描述了综合电子系统的任务需求、各功能模块原理组成、叠板结构设计、实时操作系统以及飞控软件等关键技术.重点阐述了基于Zynq处理器的主控模块最小系统及通讯接口设计、自定义高速串行总线架构设计.随着双曲线一号首飞试验的成功,作为控制中枢的综合电子系统工作正常,满足民营商业运载火箭强实时性、高可靠性以及高精度控制等要求.

Aiming at the requirement of high reliability,low cost and fast response of the private commercial launch vehicle"Hyperbola-1",a high-integrated launch vehicle integrated modular avionics is designed.This paper describes the task requirements of integrated modular avionics,the principle composition of each function module,the structure design of laminated board,real-time operating system and flight control software.Emphasis is given to the design of minimum sys⁃tem and communication interface of the main control module based on Zynq,the design of custom high-speed serial bus ar⁃chitecture.With the success of the first flight test of Hyperbola-1,integrated modular avionics,as a control center,works normally and meets the requirements of high real-time,high reliability and high precision control of private commercial launch vehicles.
