S频段统一测控雷达健康故障诊断系统的设计

针对S频段统一测控系统故障诊断及健康管理的需求,给出故障诊断软件体系架构,并基于故障树的设备故障诊断开展了LNA+D/C设备状态评估设计。健康故障诊断系统以可更换单元或模块的监测信息为基础,综合利用自动测试和标校结果,收集、存储、诊断全系统设备工作状态,并依据建立的系统健康诊断和任务能力预测模型,实现设备健康状态预测和任务能力评估功能,为资源调度提供决策依据。

The Design of Failure Diagnosis and Health Management about S-band TT&C Radar

Aiming at the needs of S-band TT C equipment failure diagnosis and health management, the paper put forward a method of software architecture of failure diagnosis system, the design is given about LNA+D/C equipment condition evaluation for failure diagnosis based on failure tree analysis. The paper based the system of failure diagnosis and health management on the monitoring message of alternative assemble and module. We can utilize the integrated result of automatic test and calibration, collect the working state in total system, and diagnose the equipment. It is realized for prognosticate health condition of equipment and ability to the mandate assessment of task. The system provides the basis of decision-making for resource scheduling.
