Hardware requirements
1. Venue
The international standard swimming pool is 50 meters long, at least 25 meters wide, and more than 2 meters deep. There are 8 swimming lanes, each swimming lane is 2.50 meters wide, and the outer lane lines of the first and eighth swimming lanes are 2.50 meters away from the pool wall.
2. Lane lines
The length of the lane lines should be consistent with the length of the track and fixed on the hooks recessed into the pool walls at both ends. The position of the hook should ensure that the buoys at both ends of the lane line can float on the water. The diameter of the lane dividing buoy is 0.05 to 0.15 meters.
3. Automatic timing device
In swimming competitions, the automatic timing system is mainly used to record the results of each athlete and determine the ranking of the athletes. The automatic timing system consists of three parts: a command device, a touch panel and a timer. At the Olympics and World Championships, automatic timing systems should also include large electronic displays and finish video systems.
