一种高性能星载综合电子系统设计

Design of satellite-based integrated electronic system with high performance

针对传统卫星系统间接口关系复杂、通用能力较弱的问题,文中将传统分系统、单机产品替换为标准模块,从而组成了星载综合电子系统。通过VPX模块化设计,各个模块接口标准化,提高了系统适用性和可扩展性;通过高低速双总线设计,极大地提高了星上数据传输效率;高速总线设计为时间触发以太网(TTE),极大地提高了星上数据传输速率和实时性。实验结果表明,采用文中设计方案的综合电子具有接口简单、通信速度快、可靠性高的特点。该系统已在某卫星综合电子中成功应用,效果良好,对星载综合电子设计具有重要的指导和参考意义。

In allusion to the complex indirect port relationship and weak general capacity of the traditional satellite system,the traditional subsystem and single machine products are replaced with standard modules to form a satellite-based integrated electronic system. The applicability and extensibility of the system are improved by means of the modular design of VPX and the standardized interface of each module;the transmission efficiency of the satellite-based data is increased vastly by means of the high and low speed dual bus design. In the high speed bus design,the Ethernet is triggered with the time,which can increase the transmission efficiency and the real-time capability of the satellite-based data. The experimental results show that the integrated electronic system in this designed scheme has the characteristics of simple interface,fast communication speed and high reliability. The system has been successfully applied in a satellite integrated electronic system with good effect,which has important guidance and reference significance for the design of satellite integrated electronic system.
