The invention discloses a short air gap ion wind parameter monitoring method. The invention belongs to the technical field of short air gap ion wind parameter monitoring. The method comprises the following two steps of: (1) monitoring the change rule parameters of the movement speed of the head of ion wind, comprising the following substeps of: a, calculating the movement speed of the head of theion wind; b, describing the movement state of the head of the ion wind through an equation according to the actual stress condition of the ion wind in an electric field, so as to obtain the ion wind X-t curves at the moments of tn to tn + 1; and integrating the curves with all sections to obtain the migration motion law of the ion wind; (2) monitoring photoelectric pulse signal parameters of the ion wind, which comprises the following substeps of: a, connecting detection equipment; b, connecting trigger equipment; c, synchronously recording a current pulse signal for generating the ionic windand an optical pulse signal for generating the ionic wind; and d, monitoring photoelectric pulse signal parameters of the ion wind. The method has relatively high detection precision and relatively high sensitivity, and has relatively high engineering practical application value.
