| 摘要 |
The invention relates to an electronic net that determines playing times in ball sports, formed by a series of optical or ultrasonic units which emit beams separated by a distance smaller than the diameter of the ball and, as such, can detect the passage of the ball. The interruption is transmitted by sensors (transmitters and receivers) housed in the net-defining elements to any type of central unit or processor, and the associated power electronics thereof, which unit converts interruptions into system interruptions and outputs times and sounds displayed and transmitted using suitable devices (displays, baffles, buzzers, horns and similar).
