LCD Soccer master the measurement system that using the Dot beam laser and the light detecting sensor of coordinates display the speed and the position of kicking soccer ball to the LCD monitor

摘要

The present invention is a system for detecting a kicked soccer ball (indoor and outdoor) and automatically displays the speed and position of the ball passed by one or more luminous dot beams installed horizontally and vertically not parallel to the kicked soccer ball. The detection frame is installed in the form of a square using the horizontal and vertical light-receiving sensors installed in correspondence with the laser. When the soccer ball passes through this space, the detection frame is detected and the passing coordinates of the soccer ball can be identified to determine the passing coordinates. By installing a horizontally emitting dot beam laser in double and a sensing frame including a light receiving unit correspondingly installed in duplicate, the speed of the soccer ball passing through the space can be accurately known. In addition, the measured data is sent to a computer, and calculations can be used to display the speed and pass coordinates on a large LCD monitor. ; Detection frame (SF), impact plate (SB), dot beam laser (DBL), horizontal dot beam laser (DBLx), horizontal start dot beam laser (DBLxs), horizontal end dot beam laser (DBLxe), vertical dot beam laser ( DBLy, Light receiving diode (LD), Horizontal light receiving diode (LDx), Horizontal starting light receiving diode (LDxs), Horizontal ending light receiving diode (LDxe), Vertical light receiving diode (LDy), Data processing part (DPB), Soccer ball (M) , Horizontal start-to-end light-receiver diode distance (W), horizontal start-to-end light-receiver detection time (T), LCD, personal computer (PC), target zone (GJ)
