Design and Implementation on Automatic Performance Testing System for Earth Station Equipment

在卫星通信地球站中,卫通设备通常会面临长时间在线使用的情况,岗位人员需要经常进行指标测试,确保设备的可靠性,以往主要根据经验通过频谱仪等设备进行手动测试,得到的结果数据记录零散、可应用性低,整套设备的性能衰减难以测量,并且难以形成持续记录分析;基于此提出自动化性能测试系统,系统通过定制嵌入式平台、性能测试流程,实现了整套地球站设备的性能测试过程,利用性能测试原理与仪器控制技术,采集处理相应节点频谱信息并计算特征值,利用多源数据进行综合判定与分析,最终获得在线设备性能测试数据,并通过曲线直观展示持续性变化情况;系统的测试结果,可帮助人员感知设备性能的变化并做好相应工作,避免设备失效对工作造成影响;系统具有快速、准确、开放性好的优点,为后续智能化运维提供了数据基础。

In satellite communication earth stations,there are often the long-term online use for satellite communication equipment and personnel need to regularly conduct indicator tests to ensure the reliability of the equipment.In the past,manual testing was mainly implemented through equipment such as spectrographs based on experience,resulting in scattered data records and low applicability.it is difficult to measure the performance degradation of entire equipment,and difficult to continuously record and analysis.Based on this,an automatic performance testing system is proposed.The system achieves the performance testing process of the entire earth station equipment by customizing the embedded platform and performance testing process.The performance testing principle and instrument control technology are applied to collect and process the corresponding node spectrum information,and calculate the characteristic values.Multiple source data are used to carry out the comprehensive judgment and analysis,ultimately obtain online equipment performance testing data,and visually display the continuous change curves of the data.The testing results show that testers can perceive the equipment performance changes and accomplish corresponding work to avoid the impact of equipment failure on work.The system has the advantages of speed,accuracy,and good openness,providing a data foundation for subsequent intelligent operation and maintenance.
