摘要
针对现有航天测控装备数字化水平偏低、结构冗杂、接口不统一等问题,提出一种数网一体化测控体系结构。该种结构依托射频数字化设备将模拟信号转换为数字信号,并设计完整的网络传输和资源池体系,优化了网络结构。为进一步提高系统的便捷、抗毁、自愈能力,设计统一接口、动态重组、故障诊断与处理、备份恢复策略。最后通过数据分析计算了新的体系结构对于测控站可靠性能的提升。
In view of the low level of digitalization,miscellaneous structure and inconsistent interface of the existing space measurement and operation control equipment,firstly,a data network integrated measurement and operation control system structure is proposed. This structure relies on the RF digital equipment to convert the analog signal into digital signal,and a complete network transmission and resource pool system is designed to optimize the network structure. In order to further improve the convenience,anti-destruction and self-healing ability of the system,the unified interface,dynamic reorganization,fault diagnosis and processing,backup and recovery strategies are designed. Finally,the improvement of reliability performance of TT & C station by the new architecture is showed through data calculation analysis.
