Problems solved by technology

If the time-based positioning method directly uses the estimated value of TOA or TDOA to solve the above-mentioned nonlinear positioning circle or positioning hyperbolic equations to determine the position of the mobile station, it is usually difficult. Curves may not have intersections and cannot be positioned normally

Embodiment Construction

[0027] Such as figure 1 As shown, a radio frequency card 100 is installed at the center of the football, and he is fixed at the center of the football by four supports (elastic supports or flexible supports or other substitutes) to the inner surface of the football. He continuously emits radio frequency signals. In addition, four radio frequency cards can also be placed at the top corners of the regular tetrahedron inscribed in the football; or multiple radio frequency cards can be glued on the inner surface of the football according to certain rules.

[0028] Such as figure 2 As shown, four positioning antennas 210, 220, 230, 240 are installed around the football field, and these positioning antennas can be installed under the stands or suspended at high places. These four antennas first locate the positions of the sideline, goal line, bottom line, etc. of the football field, so that the main control computer can first determine the position of the stadium. There are two ...

Abstract

The present invention relates to digital foot ball, basket ball, volleyball, American football, table tennis, badminton, tennis, etc. Three or more locating antennas are set around the sports ground, and thus the position of the ball may be determined by means of radio locating technology. The present invention can raise the training quality and judgment quality.

Description

technical field [0001] The present invention relates to digital ball sports (such as football, volleyball, basketball, rugby, tennis, badminton, table tennis, etc.), identification technology (Radio Frequency Identification, i.e. radio frequency identification technology) of non-contact integrated circuit cards, and wireless positioning technology. Background technique [0002] In today's football, most of the referees' subjective judgments are used to determine whether the football is out of bounds during the game, and mistakes will inevitably occur; football players often pass the ball incorrectly; high. If we can carry out fixed-point pass training in the usual training, and can automatically count the accuracy of the pass and record the flight trajectory of the football, I believe it will greatly improve the accuracy of the football player's pass, the delivery of set kicks and corner kicks. Quality; if it can automatically judge whether there is an out-of-bounds or a g...
