中文摘要：

基于分布式传感器网络结构,构建了双节点故障检测模型,分析加速度计输出,对加速度计的输出量进行重构,将与陀螺输出量耦合部分补偿掉,简化加速度计的奇偶检测方程。最后对检测方程不能识别的3个及以上加速度计出现故障的情况进行讨论,分析表明：基于量测重构的奇偶方程加速度计检测法对分布式传感器网络中的加速计故障检测有较强的检测能力。

英文摘要：

Based on structure of distributed sensor network, construct two-node fault detection model, and analyze output of accelerometers, the accelerometer output is reconstructed, compensate output coupled with gyro output simplify parity detection equations of accelerometers. Discuss condition when three or more accelerometers are failed which test equation can not identify, analysis indicates that accelerometer parity equation fault detection method based on measurement reconstruction has strong ability of detection on accelerometer fault for distributed sensor networks.
