Embodiment Construction
[0025] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0026] The specific implementation steps of a non-contact electrostatic detection method for measuring the speed of the human hand in this embodiment are as follows:
[0027] Step 1: Lay out a multi-plate detection array capable of detecting electrostatic signals of human hand movement, the detection array includes at least one set of multi-plate detection units; a schematic diagram of the relative positional relationship between the human hand and a set of multi-plate detection units is shown in figure 1 As shown, the multi-plate detection unit is composed of four plates. The four plates are divided into two pairs. The lines between the two pairs of plates are perpendicular to each other. The distance between each pair of plates is d, d≤20cm. The position of the plates is arranged in a square; the distance between the plates is d, which is re...

The invention discloses a non-contact electrostatic detection method for measuring the movement velocity of a hand, and relates to a non-contact hand movement velocity measurement method. The method comprises the following steps of: 1, arranging a multi-plate detection array capable of detecting electrostatic signals of hand movement of a human body; 2, acquiring the electrostatic signals in a monitoring environment; 3, comparing potential values of the acquired electrostatic signals with a preset criterion; 4, recording crest values of the electrostatic signals, which are detected by the step 2, of the hand movement of the human body on each plate, and reading zero crossing moments following the crest values on each plate; and 5, obtaining the movement velocity of the hand of the human body according to a formula. A non-contact electrostatic detection technology is applied to the measurement of the movement velocity of the hand of the human body, so that the working dead area of a human hand velocity measurement technology can be reduced, and complexity in the design of a human hand movement velocity detection system is lowered.
