Electronic Court Rule Lines

In this paper, multiple electronic court rule line representations with controlled LED light bars are proposed. The various court rule lines can be represented by the LED light bars which are controlled by 8051 MCU. In our designed system, the distinct rule lines can be shown for basketball, badminton, and volleyball courts, respectively. By this novel design, the drawbacks of overlapped and confused rule lines in the traditional courts can be improved. On other hand, this design can help the sportsmen to recognize relative rule lines and their positions. Furthermore, the pressure sensors are also considered into our design as an aiding judge system for the referees. In addition, when the player shot ball into the basket, the LED light bars of the court rule will flash and the recorded sound will be played with the sound module. Particularly, the RFID module is also considered as an electronic key to help user to get the authorization of the electronic court rule line system. This electronic court rule line system not only helps sportsmen and referees, but also connects them with audiences.
