Description

  The present invention relates to an automatic control system for constantly maintaining a ground environment in a good state.

  Grounds such as outdoors or indoors, that is, dome-type stadiums, take into consideration the environment of the ground itself, which affects the audience seats, that is, the spectators of the stand, regardless of whether they are competitors or those who are involved in the competition. It is extremely important to do. Therefore, by sprinkling water on the ground as needed, the competition will proceed more or less comfortably, so that the audience and supporters of the stand can comfortably support and watch without being bothered by the heat and heat. Various devices are deployed.

  However, it depends exclusively on the environment of the ground that determines the overall environment of the stadium. Therefore, it is well known that the ground environment is improved as much as possible by spraying water on the surface of the ground as necessary or by taking a certain time.

  However, in order to sprinkle water on the ground, the actual situation is that this is done exclusively by human work, such as temporarily stopping the ongoing competition or providing a special break. However, suspending the progress of the competition in this way cannot be denied to the players as well as the audience, resulting in a spoiled game.

In view of the many problems as described above, several means for supplying water to the surface layer have been disclosed so far in order to keep the surface of the ground always in a moderately wet state. . However, these water supply structures, wet artificial grass grounds, and the like have many drawbacks that are difficult to put into practical use, and unfortunately they are not implemented.
