摘　　要：自确认传感器就是一种不仅能输出测量值,同时能够对自身的工作性能、状态进行在线评估的的新一代智能传感器。本文通过对传感器模型的分析,应用时间序列分析法,建立了一个比较系统的、完整的、基于ARMA模型的自确认传感器结构,进而对自确认传感器有一个更深层的认识。最后对自确认传感器技术作了一个简单的展望。Self-validating（SEVA）sensor is a new generation of intelligent sensors, which not only can output the measurement value, but also can do the on-line assessment to its own performance and states. By analyzing the sensor model and applying the time-series analysis method, a more systematic, complete self-validating sensor structure based on the ARMA model is established in this paper. So a more profound understanding of self-validating sensor is achieved. Finally, a simple outlooks on self-validating sensor technology is presented.
