Description

Smart Ball Ball {Smart Ball}

The present invention relates to a smart baseball, and more particularly, to a smart baseball having an acceleration sensor and a gyro sensor (212) inside a baseball ball and transmitting data values measured by the acceleration sensor and the gyro sensor (212) Outputting a baseball ball and a baseball ball through a pitching operation so that the velocity and the locus of the baseball ball can be measured without a separate device.

Today, baseball is one of the most popular sports not only in Korea but also in the US, Japan, Taiwan, the Dominican Republic, Mexico, Cuba and the Netherlands.

These baseballs are experiencing a dramatic increase in the number of people who directly enjoy baseball as the number of leisure-time people increases due to the improvement in living standards.

Currently, the number of baseball teams joining the league in the domestic society is estimated to be more than '11,000 'nationwide, and as the number of clubs increases, the number of clubs who want to practice more professional is increasing.

As a result, it is a tendency to measure the game of self-regulation by using speed goggles for those who want to increase the skill level of the pitching ability of baseball players or to measure their restraint.

In the case of professional baseball teams in the United States and Japan, which are currently the baseball powerhouses, they are measuring the restraint by relying on speed guns.

However, such a speed gun is expensive equipment of 300 ~ 4000 won, and its configuration is complicated, so it is not widely available to the general public and there is a disadvantage that additional equipment is required for accurate restraint measurement.

In addition, since it is possible to measure only the limited speed such as the speed of a baseball ball by using a speed gun, it is necessary to supply a device capable of measuring a user's restraint and pitch.
