Description

TECHNICAL FIELD The present invention relates to a data storage facility for protecting data media such as magnetic tapes and magnetic disks from electromagnetic pulses (EMP) caused by nuclear explosions.

"Problems to be solved by conventional technologies and inventions" When a nuclear explosion occurs at a high altitude above the stratosphere, a strong EMP is generated within a few ns. For example, if a 1-megaton-class thing explodes at an altitude of 100 km, an EMP with a rise time of about 10 ns and a generated electric field of 50,000 V / m will be generated, and the electric field strength will be 210 dBμV / m in the range of several thousand km (2 to 3,000 km). (See FIGS. 3 and 4).

This EMP not only destroys the terrestrial information network and various electronic control devices in an instant to paralyze the system of communication, control, command, information, etc., but also uses data media such as magnetic tapes and magnetic disks. Also damage.

Currently, most of the data storages in Japan are ground-based and have a structure that can withstand earthquakes, water damage, storms, etc.
No measures have been taken against EMP.

By the way, if EMP measures are taken on the ground, it is presumed that the astronomical cost will be enormous.Therefore, in other countries such as the United States, it is considered to use underground, but it is still sufficient. Is not disclosed.

In addition, conventional data storage often depends on obtaining data cases from loading to storing in a storage case, and management in a complicated maze underground is impossible.

The present invention is intended to solve such conventional problems.

"Means for Solving the Problem" The present invention is to excavate a main shaft of a side shaft or an inclined shaft from the surface to the ground, to excavate a vertical shaft connected to the main shaft, and to connect to the vertical shaft of a horizontal shaft or an inclined shaft. Multiple branch tunnels are excavated, underground storages are provided at the tip of each branch tunnel, belt conveyors are installed in the main tunnel and each branch tunnel, elevators are installed in the vertical shaft, and automatic storage shelves are installed in the storage cabinets all over the place. , The main tunnel, the vertical shaft, each branch tunnel, and the doorway of the storage in each place, doors are provided respectively, and electromagnetic shielding means is provided in these doors and storage in each place, and further, these doors, belt conveyors, elevators and automatic It consists of a series of continuous automation measures for storage shelves.

"Effect" Because of the above structure, the incoming EMP is absorbed and eliminated into the ground, and it is difficult to enter the tunnel, and even if it enters, the doors and underground storages arranged in multiple layers are It is removed to the ground by the electromagnetic wave shielding means and does not reach the inside of the underground storage.

For loading, unloading, and storage of data media, doors, belt conveyors, elevators, and automatic storage shelves are automatically operated by continuously operating them one after another under certain conditions.

[Examples] FIGS. 1 and 2 are examples of the present invention. In the illustrated facility, a cargo handling field 1 is provided at an appropriate place on the surface of the ground in a mountain or the like, and a side pit is connected to the cargo handling site to the ground. And a main shaft 2 composed of an inclined shaft, an underground management center 3 and an air-conditioning and other mechanical / electric room 4 are provided at the tip of the main shaft, and a deep vertical shaft 5 is drilled in connection with the underground management center. A plurality of branch shafts 6 of the inclined shaft are connected to the vertical shaft to excavate, an underground storage 7 is provided at the tip of the nuclear branch shaft, a belt conveyor 8 is connected to the main shaft 2 and each branch shaft, and a vertical shaft 5 An elevator 9 is installed at the above-mentioned loading / unloading site 1, main tunnel 2, underground management center 3, vertical shaft 5,
Doors 11,21,31,51,61,61 ..., 71 ... are provided at the entrances of the branch roads 6 ... and storages 7 ... There is.

In addition, spray mortar 10 is applied to the mine walls of the main gallery 2 to the storage shed 7 ...

The underground storage 7 has a box 75 of reinforced concrete whose periphery is supported by a supporting member 74 in a dug out space, and an entrance 76 facing the branch tunnel 6 is provided in the box 75, and the above-mentioned entrance is provided at the entrance. A door 71 is provided, zinc spraying 72 is applied to the inner surface of the box, and an electromagnetic wave shielding means is provided. Thus, an automatic storage shelf 73 is arranged in the cabinet, and data storage in which a data medium is accommodated in the automatic storage shelf is stored. I am trying to accommodate Case A.

By the way, the doors 11, 21, 31, 51, 61 ..., 71 ..., the belt conveyors 8 ..., the elevators 9 and the automatic storage shelves 73 ... at various places are continuously automated, and by the management system centered on the management center 3, By automatically controlling, the data storage case A ... Is transferred from the cargo handling area 1 to a predetermined underground storage 7 ...
Then, the data is automatically loaded / stored in the automatic storage shelves 73, and on the contrary, it is automatically loaded / unloaded, and the data storage case A ... The stock is managed in real time so that the storage status can be confirmed in real time.

Therefore, in the facility of this embodiment, unmanned operation can be carried out, and carry-in / carry-out / storage can be done in an orderly manner, and inventory management can be performed well.

"Effects of the Invention" According to the present invention, the following effects are achieved.

i. The EMP due to the nuclear explosion will not enter the underground storage, and the data media such as magnetic tape and magnetic disk will be EM.
We can fully protect from damage of P.

ii. Abandoned mines can be used and can be obtained easily and at low cost.

iii. Since the temperature and humidity of the underground space are constant without the influence of the outside air, it is easy to control the temperature and humidity, and stable management is performed at the optimum temperature of 20 ° C ± 2 ° C and humidity of 50% ± 10%. it can.

IV. Data media can be automatically loaded and unloaded, stored, and managed in an orderly manner, making it easy to check the storage status.

V. The electromagnetic wave shielding means of the underground storage can be simply made by spraying zinc spray on site.
