Embodiment Construction
[0054] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0055] Such as figure 1 As shown, the intermittent fault detection method of the high-speed train closed-loop braking system specifically includes the following steps:
[0056] Step 11. Offline training:
[0057] 111. Assuming that the high-speed train closed-loop braking system contains m sensors, and the sampling time of the m sensors is the same, then continuously collect N sample data under normal single working conditions, and construct the normal Working condition measurement matrix:
[0058] [X 1 ,X 2 ,...,X N ]∈R m×N (1)
[0059] Among them, X k ∈R m×1 is a column vector;
[0060] 112. Augment the measurement data according to formula (2), and construct the augmented measurement matrix X∈R N×Wm :
[0061]
[0062] Among them, W is the length of the augmented window, and its initial value is taken as ...
