航天器用无线健康监测系统设计

Design of Wireless Health Monitoring System for Spacecraft

航天器面临重复起降以及大温差、强振动以及剧烈冲击的复杂使用环境,为提升其使用性和维护性,提升航天器全生命周期内对其结构体能力数据的获取,需全天候监测航天器结构体的健康状况,并开展结构健康管理技术研究。通过无线的方式实现对航天器内外各敏感测点的数据采集、数据传输并汇总处理数据,实现航天器结构体全方位全天候健康监测的功能。本文对航天器用无线健康监测系统开展了设计研究,并实现了航天器无线健康监测系统的原理样机实施。

Spacecraft faces a complex environment of repeated takeoff and landing,large temperature difference,strong vibration and severe impact.In order to improve its usability and maintainability,and enhance the acquisition of the structural capacity data of the spacecraft in the whole life cycle,it is necessary to monitor the health status of the spacecraft structure all day long and carry out research on structural health management technology.The data acquisition,transmission,collection and processing of the sensitive measuring points inside and outside the spacecraft are realized by wireless,and the all-round all-weather health monitoring function of the spacecraft structure is realized.The design of wireless health monitoring system for spacecraft is studied.The prototype implementation of wireless health monitoring system for spacecraft is realized.
