Definitions

  • Patent Document 1 it is necessary to use a plurality of sensors, and the user's swing is detected by comprehensively analyzing the information obtained from these sensors. That is, there is a possibility that the structure of the device becomes complicated and the processing becomes complicated.
  • the timing at which the columnar portion of the sports equipment impacts a desired object with a simple structure.
  • the sports equipment is a golf club
  • the timing at which the golf club impacts the golf ball can be detected more accurately.
  • the impact detection device 10 includes a transmission side device 11 and a reception side device 12 . As shown in FIG. 1 , transmitting device 11 is attached to the surface of shaft 201 of golf club 200 .
  • the sensor signal generation unit 120, the feature data extraction unit 130, and the communication unit 140 are realized, for example, by a plurality of electronic circuit elements such as ICs mounted on a circuit board or the like.
  • the sensor signal generation section 120 outputs the sensor signal to the feature data extraction section 130 .
  • the AD converter 131 AD-converts (analog-to-digital converts) the sensor signal.
  • the AD converter 131 outputs the digitized sensor signal to the impact timing detector 132 .
  • the feature point extraction unit 133 extracts a sensor signal of a predetermined length of time from the impact timing and outputs it as the feature point extraction unit 133 . More specifically, the feature point extraction unit 133 cuts out several seconds (for example, two seconds) before and after the impact timing. As shown in the graph of FIG. 5, the feature data extraction section 130 extracts a plurality of feature points from the clipped result.
  • the false detection determination unit 135 determines whether an abnormality has occurred in the feature point. A more specific flow of processing will be described with reference to FIGS. 8 and 9.
  • FIG. 9 the feature data extractor 130 extracts a plurality of feature points F5, F6, F7 and F8.
  • the false detection determination unit 135 determines the size of each feature point using a reference voltage (reference voltage V3 in this case).
  • the erroneous detection determination unit 135 determines that the amplitude of the voltage with respect to the reference voltage V3 is too small at the feature points F5 and F6 (between V2 and V4). In this case, the erroneous detection determination unit 135 determines that the contact failure of the impact detection device 10A has occurred. Also, at the characteristic point F8, it is determined that the amplitude of the reference voltage V3 is too large (V1). In this case, the erroneous detection determination unit 135 determines that the voltage is saturated. On the other hand, the erroneous detection determination unit 135 determines that the characteristic point F7 is normal.
  • the feature data extraction unit 130 determines whether to continue subsequent processing. At this time, if at least one abnormal value occurs, the feature data extraction unit 130 may suspend the process and display a warning message or the like.
  • the impact detection device 10B has the configuration of the transmitting device 11 and the receiving device 12 according to the first embodiment. It differs from the impact detection device 10 .
  • Other configurations of the impact detection device 10B are the same as those of the impact detection device 10, and descriptions of the same parts are omitted.
