Description

Technical Field

[0001] This utility model relates to the field of electromagnetic shielding room technology, and in particular to a data processing center that resists electromagnetic interference. Background Technology

[0002] As the core location for information storage, processing, and transmission, the data processing center houses a large number of electronic components such as servers, switches, storage devices, and power modules. These devices generate complex electromagnetic signals during operation and are also susceptible to external electromagnetic interference, such as electromagnetic effects from lightning, high-voltage power lines, and wireless devices. This can lead to data transmission errors, equipment failures, or even system crashes, severely impacting the normal operation of the data processing center.

[0003] Existing electromagnetic interference (EMI) mitigation measures often employ a single shielding structure or a simple filtering circuit, which has limited effectiveness against high-frequency, broadband, and complex electromagnetic environments. Furthermore, they lack systematic interference detection and dynamic adjustment mechanisms, failing to meet the EMI mitigation requirements of data processing centers.

[0004] Therefore, in order to address the above problems, this utility model urgently needs to provide a data processing center that is resistant to electromagnetic interference. Utility Model Content

[0005] The purpose of this invention is to provide a data processing center that resists electromagnetic interference. By combining a shielded room with a double-layer metal mesh structure and an interference monitoring and filtering unit, it solves the problems of limited anti-electromagnetic interference effect and lack of dynamic adjustment in the existing technology.

[0006] An electromagnetic interference resistant data processing center includes a shielded room and a shielded cabinet placed inside the shielded room. Data processing equipment is placed inside the shielded room. The server and switch of the data processing equipment are placed inside the shielded cabinet, and the side wall of the shielded cabinet is provided with through holes for wiring.

[0007] The shielded equipment room consists of a first metal mesh layer, an insulation layer, and a second metal mesh layer from the outside in.

[0008] The shielded cabinet includes a metal cabinet body and a metal cabinet door that are hinged together. A conductive sealing strip is provided between the cabinet door and the cabinet body. A third metal mesh is provided on the cover of the cable hole.

[0009] Furthermore, it also includes a power filter installed on the main power line and a signal filter installed on the signal transmission line.

[0010] Furthermore, multiple electromagnetic sensors are spaced apart on the inner surface of the shielded room and the inner surface of the shielded cabinet. Each electromagnetic sensor is electrically connected to the controller, and the power filter and signal filter are electrically connected to the controller respectively.

[0011] Furthermore, a power filter is installed at the main power line inlet of the data processing center.

[0012] Furthermore, the signal transmission line includes a network cable, coaxial cable, or optical fiber, and each signal filter is installed in series at the interface of the signal transmission line.

[0013] Furthermore, the grounding resistance of the shielded equipment room is less than or equal to 1Ω.

[0014] Furthermore, the power supply filter is a three-phase power supply filter, and the signal filter is a data filter.

[0015] Furthermore, conductive pads are laid inside the shielded cabinet, with the server and switch placed on top of the conductive pads.

[0016] Furthermore, the first metal mesh layer is made of stainless steel, the second metal mesh layer is made of copper, and the insulating layer is made of rubber.

[0017] Furthermore, both the cabinet doors and the cabinet body are made of cold-rolled steel sheets.

[0018] The electromagnetic interference resistant data processing center provided by this utility model has the following advantages compared with the prior art:

[0019] The electromagnetic interference-resistant data processing center provided by this utility model, by setting up a shielded room 1 and grounding it, can guide electromagnetic waves to the ground or other designated paths, dissipating their energy and avoiding interference with the surrounding environment and other equipment. It can also block the entry of external electromagnetic waves, preventing them from affecting the operation of the data processing center. By installing a shielded cabinet 2 inside the shielded room 1, servers and switches that are more likely to generate more electromagnetic signals and are more susceptible to electromagnetic influences can be placed inside the shielded cabinet 2, forming a multi-layered electromagnetic shielding system. This effectively blocks external electromagnetic interference from entering the data processing center and prevents electromagnetic leakage from internal equipment, improving the overall shielding effectiveness. By installing filters on power lines and signal transmission lines, targeted filtering of power and data signals is performed, reducing the impact of electromagnetic interference on equipment operation and data transmission, ensuring data accuracy and equipment stability. By installing electromagnetic sensors in locations susceptible to electromagnetic influences and connecting them to a comparison module, controller, and filter, real-time monitoring and dynamic adjustment of the electromagnetic environment can be achieved. This allows for rapid response to electromagnetic interference of different types and intensities, significantly improving the flexibility and effectiveness of electromagnetic interference resistance compared to traditional fixed protection modes.

[0028] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the present invention provides an electromagnetic interference resistant data processing center, including a shielded room 1 and a shielded cabinet 2 placed inside the shielded room 1. Data processing equipment is placed inside the shielded room 1; wherein, the server and switch in the data processing equipment are placed inside the shielded cabinet 2, and a through hole 201 is provided on the side wall of the shielded cabinet 2.

[0032] The shielded equipment room 1 includes, from the outside to the inside, a first metal mesh layer 101, an insulating layer 102 and a second metal mesh layer 103;

[0033] The shielded cabinet 2 includes a metal cabinet body 202 and a metal cabinet door 203 that are hinged together. A conductive sealing strip 204 is provided between the cabinet door 203 and the cabinet body 202. A third metal mesh is provided on the cover of the cable hole 201.

[0034] In this invention, by setting up a shielded room 1 and grounding it, electromagnetic waves can be guided to the ground or other designated paths to dissipate their energy and avoid interference with the surrounding environment and other equipment. It can also block the entry of external electromagnetic waves, preventing them from affecting the operation of the data processing center. By installing a shielded cabinet 2 inside the shielded room 1, servers 8 and switches 7, which are more likely to generate electromagnetic signals and are more susceptible to electromagnetic influences, are placed inside the shielded cabinet 2, forming a multi-layered electromagnetic shielding system. This effectively blocks external electromagnetic interference from entering the data processing center and prevents electromagnetic leakage from internal equipment, improving the overall shielding effectiveness. By installing filters on power lines and signal transmission lines, power and data signals are filtered in a targeted manner, reducing the impact of electromagnetic interference on equipment operation and data transmission, ensuring data accuracy and equipment stability. By installing electromagnetic sensors in locations susceptible to electromagnetic influences and connecting them to a comparison module, controller, and filter, real-time monitoring and dynamic adjustment of the electromagnetic environment can be achieved. This allows for rapid response to electromagnetic interference of different types and intensities, significantly improving the flexibility and effectiveness of electromagnetic interference resistance compared to traditional fixed protection modes.

[0035] In this invention, springs, conductive shielding gaskets, and conductive fillers can also be used to fill the gap between the cabinet 202 and the cabinet door 203. Among them, the spring material is suitable for gap design in communication, computer, shielded room and other equipment, and has the characteristics of high shielding effectiveness, high thermal conductivity and good pressure resistance. The conductive shielding gasket, especially the rubber core woven mesh shielding gasket, can be used to increase the shielding effect and reduce electromagnetic wave leakage, or the conductive rubber shielding gasket made of conductive rubber has good conductivity and shielding performance and can be used for chassis and cabinet gap shielding. The conductive filler is used to fill the gaps in the shielding body and improve the shielding effectiveness.

[0036] like Figure 1 , Figure 2 As shown, it also includes a power filter 3 installed on the main power line and a signal filter 5 installed on the signal transmission line.

[0037] Specifically, the power supply filter 3 includes models such as T110-3CL, T110-6CL, and FN3026HP-10-71, while the signal filter 5 includes models such as TFNM-S, TFNM-P, and BPFOTF-2.

[0038] In this utility model, such as Figure 1 , Figure 2As shown, the main power line enters from the entrance of shielded room 1, passes in parallel through the server 8 and switch 7 placed inside shielded cabinet 2, and other components 9 of the data processing center placed inside shielded room 1, before exiting from the exit of shielded room 1. The signal transmission line enters from the entrance of shielded room 1, passes through each component in sequence, connects the components in parallel, and exits from the exit of shielded room 1. When the power filter 3 is installed at the entrance of the main power line and the signal filter 5 is installed at the interface of the signal transmission line, the filtering efficiency is maximized, which can filter the electromagnetic waves generated by the power line and the signal transmission line to avoid affecting the normal operation of the data processing center.

[0039] like Figure 5 As shown, multiple electromagnetic sensors are spaced apart on the inner surface of the shielded room 1 and the inner surface of the shielded cabinet 2. Each electromagnetic sensor is electrically connected to the controller, and the power filter 3 and the signal filter 5 are electrically connected to the controller respectively.

[0040] In this invention, the controller includes a comparison module and a control module. The comparison module is electrically connected to each electromagnetic sensor. The electromagnetic sensors collect electromagnetic interference signals in real time and transmit the data to the comparison module. The comparison module compares the electromagnetic values ​​measured by each electromagnetic sensor with a set threshold and sends the comparison result to the control module. The control module is electrically connected to the power filter 3 and the signal filter 5 and is used to dynamically adjust the filtering power of the power filter 3 and the signal filter 5 according to the comparison result of the comparison module.

[0041] Specifically, electromagnetic interference can be divided into multiple levels. The comparison module sends signals to the control signal according to different levels based on the electromagnetic threshold obtained by the electromagnetic sensor. The control signal controls the filter to filter with different levels of filtering power to achieve dynamic protection against electromagnetic interference. When the electromagnetic interference in the environment is strong, the filter uses higher filtering power to keep the electromagnetic intensity at a low level. When the electromagnetic interference in the environment is weak, the filter uses lower filtering power to save power. The filter on the power line filters the input of the main power line, and the data filter on the signal transmission line filters the signals transmitted through network cables, optical fibers, etc., to eliminate electromagnetic interference in the power line and signal transmission process.

[0042] like Figure 1 , Figure 2 As shown, power filter 3 is installed at the main power line inlet of the data processing center.

[0043] like Figure 1 , Figure 2 As shown, the signal transmission line includes a network cable, coaxial cable, or optical fiber, and each signal filter 5 is connected in series at the interface of the signal transmission line.

[0044] In this embodiment, the grounding resistance of the shielded equipment room 1 is less than or equal to 1Ω.

[0045] In this invention, the shielded equipment room 1 is effectively grounded, which can guide electromagnetic waves to the ground, dissipate their energy, avoid interference with the surrounding environment and other equipment, help reduce static electricity accumulation, and provide a more stable working environment.

[0046] In this embodiment, the power supply filter 3 is a three-phase power supply filter, and the signal filter 5 is a data filter.

[0047] In this invention, a three-phase power filter is installed on the main power line 4 to suppress common-mode and differential-mode interference on the power line, and a data filter is installed on the signal transmission line 6 to filter signals transmitted through network cables, optical fibers, etc., and eliminate electromagnetic interference during signal transmission.

[0048] In this embodiment, a conductive pad 206 is also laid inside the shielded cabinet 2, and the server and switch are placed on top of the conductive pad 206.

[0049] In this embodiment, the first metal mesh layer 101 is made of stainless steel, the second metal mesh layer 103 is made of copper, and the insulating layer 102 is made of rubber.

[0050] In this embodiment, both the cabinet door 203 and the cabinet body 202 are made of cold-rolled steel sheet.

[0051] In this invention, a main power line 4 and a signal transmission line 6 are introduced through a perforation in the shielded room 1. The main power line 4 is divided into multiple circuits and connected to the server 8, the switch 7, and other components 9 of the data processing center. The signal transmission line 6 is connected in series with the server 8, the switch 7, and the other components 9 of the data processing center. A power filter 3 and a signal filter 5 are installed at the entrance of the main power line 4 and on the signal transmission line 6, respectively, for dynamic filtering. The processor and the switch are then placed in the shielded cabinet 2 for secondary shielding. Multiple electromagnetic sensors are installed inside the shielded room 1 and connected to the power filter 3 and the signal filter 5 through a comparison module and a control module, thereby enabling controllable dynamic filtering of electromagnetic waves inside the shielded room 1.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
