Aiming at the problems of low detection accuracy and poor robustness of the existing zero-speed detection methods, an effective gait cycle segmentation method is adopted and a Bayesian network model based on inertial sensor measurements and kinematics knowledge is introduced to infer the zero-speed interval;The method can effectively reduce the ambiguity of the zero velocity (ZV) boundary. Support vector machine has the advantages of versatility, simple calculation, high operation efficiency and perfect theory. It is a relatively mature and efficient algorithm in the current network security situation algorithm. And a looped Bayesian network model for probabilistic safety assessment of simple feedback control systems is established.
