摘要:

在传输气象卫星遥感数据的过程中, 为了解决由干扰或衰减引起的信号质量下降对气象卫星遥感数据接收故障诊断精确性的影响,研究设计一种基于规则匹配的气象卫星遥感数据接收故障诊断系统。该系统硬件单元分别为卫星数据接收故障诊断框架搭建单元、卫星数据接收状态监控单元、卫星数据接收故障推理机设计单元与卫星数据接收故障诊断报告生成器设计单元。系统软件部分首先对卫星数据接收状态信号预处理,提取接收状态信号与接收故障信号的特征,设计卫星数据接收故障诊断规则库,基于规则匹配实现卫星数据接收故障诊断。通过硬件与软件的共同协作实现了气象卫星遥感数据接收故障诊断系统的设计与运行。实验数据显示,应用设计系统获得的卫星数据接收状态信号特征提取结果与实际接收状态信号特征相同,卫星数据接收故障诊断结果与实际接收故障诊断结果相同,证实了设计系统的有效性。

Abstract:

In the process of transmitting meteorological satellite remote sensing data, in order to address the impact of signal quality degradation caused by interference or attenuation on the accuracy of meteorological satellite remote sensing data reception fault diagnosis, a rule matching based meteorological satellite remote sensing data reception fault diagnosis system is studied and designed. The hardware units of the system are respectively the building unit of the satellite data receiving fault diagnosis framework, the monitoring unit of the satellite data receiving status, the design unit of the satellite data receiving fault inference machine, and the design unit of the satellite data receiving fault diagnosis report generator. The system software first preprocesses the satellite data reception status signal, extracts the characteristics of the received status signal and the received fault signal, designs a satellite data reception fault diagnosis rule library, and implements satellite data reception fault diagnosis based on rule matching. The design and operation of a fault diagnosis system for meteorological satellite remote sensing data reception have been achieved through the collaboration of hardware and software. The experimental data shows that the feature extraction results of satellite data reception state signals obtained by the application design system are the same as the actual reception state signal features, and the fault diagnosis results of satellite data reception are the same as the actual reception fault diagnosis results, confirming the effectiveness of the design system.
