Cheetah cameras run faster than athletes.

Cheetah cameras run faster than athletes.

Introduction of cheetah camera:

"Cheetah" is a 4K high-speed camera independently developed by the Central Radio and Television General Station for several years. It belongs to the special equipment for live TV broadcast, which is specially used for the relay of speed skating events. The "ice belt" has a track with a total length of more than 300 meters, which is similar to a U-shape. Cheetah can track and shoot at high speed in straights and corners.

Advantages of cheetah camera:

It can not only track the position of athletes in real time, but also realize actions such as acceleration, deceleration and overtaking according to the broadcast requirements, flexibly capture the game picture, and let the audience clearly watch the performance of athletes from multiple angles. In the speed skating competition, the speed of top athletes can reach 70 kilometers per hour.

"Cheetah" runs faster, and its design technical standard can reach 25 meters per second, which is about 90 kilometers per hour. In addition to running fast, cheetahs can turn at high speed. Four pairs of side wheels hold the cheetah tightly on the track. When turning, the side roller provides lateral force, and the motor provides forward force, which realizes high-speed turning and captures the wonderful moments of athletes on straight and curved roads.

Speed skating "black technology";

Pneumatic training:

In the wind tunnel, short track speed skaters will stand on special sensors. When the wind in the wind tunnel blows head-on, the sensor can measure the change of resistance in different postures, so that athletes and coaches know which action can get the least wind resistance. After locking the movements and postures with the least wind resistance, the players will conduct repeated training to form muscle memory.

"Shark skin":

The drag reduction technology of air turbulence control and boundary sliding is adopted in the winter Olympics clothing. Compared with ordinary skating clothes, the drag reduction can be increased by 5%- 10%, and the strength is five times that of steel wire. This specially shaped structure is used on the surface of clothes to guide air quickly. Finally, through the wind tunnel test, the version and the best position of the human body dividing line are tailored and adjusted for each athlete to optimize and upgrade the drag reduction performance.

At the same time, this set of "shark skin on ice" high elastic anti-cutting fabric can firmly wrap the muscles of athletes and avoid the influence of body shaking on the competition. Using Dyneema anti-cutting technology, the original double-layer structure is improved to single-layer full-body anti-cutting, and the anti-cutting strength can reach 15 times of that of steel wire, with higher safety factor and lighter weight, which reduces the load of athletes.
