Generally, a warehouse automation system is installed in a warehouse or a warehouse to temporarily store or store various kinds of foods, beverages, clothes, household appliances and miscellaneous goods produced in the factory or production site. Such an automation system has been effectively used for efficient warehousing, warehousing, warehousing, inventory management, as well as product placement of products stored in a warehouse, away from simple logistics storage due to the development of the logistics industry. In addition, automation systems are being designed and constructed in a variety of ways for faster loading and unloading of large quantities of articles as well as efficient use of loading space.

Recent warehouses to which such automated systems are applied are generally in the form of rack warehouses to store large quantities of goods more efficiently.

The rack-type warehouse is configured in such a manner that rack modules in which a plurality of article-carrying shelves are stacked in a horizontal and vertical direction are arranged along a plurality of rows and columns, and individual articles are stacked on each of the article-carrying shelves.

As described above, the rack-type warehouse is structured such that the product loading shelves are stacked continuously in the horizontal and vertical directions, and the various articles are stacked on the product loading shelves, so that they are structurally very vulnerable to fire suppression by sprinkler watering .

The fire-extinguishing system of the rack-type warehouse is constructed in such a manner that a sprinkler that operates in the event of a fire is mounted on the ceiling inside the warehouse, like a general building.

However, if a fire occurs inside a rack-type warehouse, even if the fire water is sprayed from the sprinkler mounted on the ceiling, there is a product loading shelf according to the structure of the rack module. As a problem of sprinkler water spraying, It is difficult to spray, and it is not easy to enter the fire point or the garden directly. That is, since the rack rack module is formed by stacking a plurality of racks in the horizontal and vertical directions, the water to be sprayed by the sprinkler is supplied only to the uppermost racks of rack modules, The water is not supplied normally. Particularly, since various articles are loaded on each article loading shelf, supply of such digested water becomes more difficult.

Therefore, fire extinguishment can not be achieved at the early stage by such general fire extinguishing facilities, and there is a problem that the fire is spread rapidly in an instant. In addition, there is a problem in the effect of the sprinkler facility installed for the purpose of initial fire fighting and fire suppression, and there are management problems such as the cost and damage of the sprinkler head when the sprinkler is installed on each shelf layer.
