摘要
时间应力测量(TSMD)技术是一种测量和存储各种环境应力数据,以及对这些数据进行相关分析的技术。本文简要介绍了时间应力测量技术的原理及其发展历程,并对其研究现状及发展趋势作了详细描述。在此基础上,将BIT的测试信息和TSMD的环境应力信息相结合,并利用双支持向量机的诊断和降虚警技术进行综合决策,以提高地平仪在复杂环境下的状态识别能力。最后,笔者通过温度和振动应力试验对该地平仪自诊断系统的有效性进行了验证。TSMD技术在该系统的应用结果表明,其在地平仪降低虚警方面的应用具有良好的效果,并可推广应用到其它相应的诊断系统中。
TSMD is a measurement and recording technology that can be used for stress history recording and data analyzing, In this paper, the principle and development history of TSMD are introduced in brief, some problems and the developments of TSMD are described in detail. And then, In order to improve the state recognition capability of the self-diagnosis system in complex environment, we used two support vector machines （SVM） and combined BIT information with TSMD information to estimate the working state of the gyro horizon. At last, the validity of the system is proved by temperature and vibration stress test. The successful application of TSMD technology in the system shows that TSMD technology can reduce false alarms effectively and can also be applied in other similar systems.
