Description

  The present invention relates to a security room that is independently installed in a building room to store and protect security objects. More specifically, the present invention relates to a security object such as a server or router that is a communication device or a database. The present invention relates to a security room that is housed in order to protect against electromagnetic waves and intruders.

  In recent data centers and communication equipment rooms, instead of being operated by one company, various companies share the same floor, co-location for lending to other companies, and hosting for lending server racks. However, there are increasing cases of floor operation.

  In the past, when one operator operated and managed, it was easy to manage the belongings carried by maintenance workers, but as the use of portable wireless devices and the spread of power tools spread, operators became unconscious. There are increasing cases of bringing in a PC equipped with a mobile phone, a wireless LAN, or the like, or bringing in an electric tool having a large electromagnetic radiation, an igniter such as a gas solder iron that also emits impulse electromagnetic noise, and the like.

  On the other hand, devices such as servers have a resistance to electromagnetic waves defined by CISPR24 and ITU-T K48, but these standards do not specify a tolerance of 1 GHz or higher, which is the frequency of portable devices. Even if the radio frequency is a prescribed frequency, the proof strength corresponding to the intensity of the electromagnetic wave in the immediate vicinity of the portable wireless device is not prescribed.

  In highly public data centers and communication machine rooms, high reliability and security are required, and ingenuity is required to keep workers away from other companies' equipment. In addition, it is easy to purchase a static generator called a small stun gun, and there is an increased possibility that the server or communication device is intentionally attacked by electromagnetic waves, causing a malfunction or malfunction.

  In addition to the position of protecting servers and communication devices as described above, in recent years, technologies related to information leakage such as TEMPEST that steals information by receiving undesired radiated radio waves from these devices at remote locations and reproducing the signals have been developed in recent years. Now that it is widely available on the Internet, it is necessary to devise a means to reduce such unnecessary radiation.

  Further, in a general office environment, office residents are required to freely use a wireless LAN, a mobile phone, and the like, but when a server or a communication device is installed on the same floor, the same thing as described above occurs.

  Conventionally, when a building is shielded, an electromagnetic shielding work is performed to completely enclose the entire inner wall of the building with a conductive material such as metal before the interior work after the building frame work. Shielding work with an electromagnetic wave performance of about 30 dB or more requires a dedicated shield member for windows and doors, and it is difficult to shield the electromagnetic wave at the joint between the metal foil or metal mesh on the wall or ceiling and the dedicated member. The construction period was long. In addition, since it is necessary to evaluate the shield performance with antennas facing inside and outside the building even after trial and error, it has been difficult to evaluate the shield performance in a building having two or more floors. Furthermore, in order to partially shield existing buildings, it becomes more difficult to shield the joints between the ceiling and walls, etc., and the shielding performance is maintained by unevenness and wiring of piping, lights, fire alarms, etc. in the building It was difficult to remove these irregularities, wiring, etc., and there were problems in terms of construction period and cost.

  Also, when building a shield room in a building, there is a shield room with a prefabricated panel method, but it is difficult to measure the shield performance or the shield room wall comes close to the existing building wall Measurement for confirming shielding performance is difficult. In such a case, in order to ensure the desired shielding performance, it is necessary to use a lot of soldering or welding with poor workability, screwing with a tighter pitch between screws than necessary, or expensive conductive gaskets. There were problems with construction period, workability, and cost.

  When electromagnetically shielding a single server rack or a plurality of server racks, it is common to install a shield room of a size that can be accommodated inside the server rack by combining floor panels, wall panels, ceiling panels, etc. . However, in order to perform server rack installation work in a shielded room, and to perform server and router mounting and maintenance work, the internal dimensions of the server rack must be large enough for the server rack. Since it is selected and combined from those of a certain standard size, it is inevitably larger than the space occupied by the server rack, and the space utilization efficiency of the entire room is reduced.

  Also, in order to support the weight of the ceiling panel in the shielded room and provide the necessary earthquake resistance, it is necessary to support each panel by strengthening each panel or by using a pillar or beam material separately from the panel. In addition, the size and weight of the members increase or the number of members increases, which not only increases the cost, but also impairs the workability and restricts the installation due to floor load restrictions, so that it cannot be easily introduced.

Furthermore, in order to ensure earthquake resistance, the shield room must be firmly fixed to the floor of the room. In general, a double rack is used in the server rack installation room. Complex work such as installing bolts and mounts was necessary.

There is a problem that a failure such as a malfunction may occur due to electromagnetic radiation from other communication devices installed on the floor or the like or intentional electromagnetic radiation by a malicious person.

  In order to avoid such problems caused by electromagnetic radiation, there is a conventional method of shielding the entire room of the building or the installation location. However, as described above, it is difficult to shield the electromagnetic wave at the joint portion, and the construction period becomes long. In the above buildings, it is difficult to evaluate the shield performance, it is difficult to maintain the shield performance due to unevenness and wiring in the building, and it takes construction period and cost if removing the unevenness and wiring etc. and newly installing There is.

  In addition, in order to avoid problems caused by electromagnetic radiation, when creating a shield room in a building, it is difficult to install it close to the wall of the building for confirmation of the shielding performance. There are problems in terms of work period, workability, and cost.
