[0002] At present, as customers' computing demands for servers increase, multiple server nodes are placed in a server cabinet. In the prior art, a locking structure is usually used to fix the cabinet and the server node. Workers need to use specific tools near the computer room to disassemble and assemble the server node. The server maintenance process is complicated and the manual operation cost is high. Summary of the invention

[0003] The present application provides a cabinet server and a control method for the cabinet server, which are beneficial to improving the degree of automated management of the cabinet server and reducing the difficulty of operation and maintenance of the cabinet server.

[0004] In the first aspect, the present application provides a cabinet server, which includes: a cabinet, at least one distance sensor, at least one first magnetic component and a controller. Among them, the cabinet includes a cabinet backplane and multiple installation positions, the cabinet backplane is located at the rear end of the multiple installation positions, the front end of each installation position has an installation port, the first magnetic component is installed on the cabinet backplane, and the rear end of each installation position is provided with a distance sensor and a first magnetic component, each distance sensor and each first magnetic component are connected to the controller, and each installation position is used to install a server node. In the process of inserting the server node into the installation position along the installation port of the installation position, the distance sensor in the same installation position is used to detect the distance from the server node, and the controller is used to control the first magnetic component in the same installation position to generate a first magnetic force when the distance is less than or equal to the first threshold, and the first magnetic force is used to adsorb the second magnetic component located on the server node. That is, the controller can realize the automatic insertion and fixation of the server node by controlling the mutual attraction between the first magnetic component and the second magnetic component. This process does not require manual operation, the cabinet server has a high degree of automation management, and the fixing method of the server node is simple.

[0005] In one possible implementation, the first magnetic component is fixed to the cabinet backplane, the server node includes a node backplane, the node backplane is arranged facing the cabinet backplane, and the second magnetic component is fixed to the node backplane. In this case, the magnetic force between the first magnetic component and the second magnetic component will be parallel to the plug-in and unplug direction of the server node. This is conducive to improving the utilization efficiency of the magnetic force between the first magnetic component and the second magnetic component.

[0006] In one possible implementation, the first magnetic component includes a plurality of electromagnets, and the plurality of electromagnets are symmetrically arranged about the center line of the cabinet backplane. In this case, the magnetic force between the first magnetic component and the second magnetic component is evenly distributed, which is conducive to ensuring the stability of the server node sliding process.

[0007] In one possible implementation, the distance sensor is fixed to the cabinet backplane. In this case, the detection value of the distance sensor can directly correspond to the distance between the distance sensor and the node backplane, and the processor can obtain the position of the server node during the plug-in process.

[0008] In one possible implementation, the cabinet server further includes a vacuum suction cup, which is installed at the installation position and fixed to the cabinet back plate, and is used to absorb the server node. After the server node has been installed, the vacuum suction cup can fix the server node. At this time, the first magnetic component does not need to be continuously powered on, which is conducive to saving energy consumption of the first magnetic component.

[0009] In one possible implementation, the cabinet includes a bracket, the bracket is installed in the internal space of the cabinet, and the bracket is fixedly connected to the cabinet backplane; the server node also includes a node bottom plate and a rolling member, the node bottom plate is arranged toward the bracket, the rolling member is installed on the node bottom plate, and the rolling member contacts the bracket. In this case, the server node can achieve a sliding connection with the cabinet through the rolling member. During the plug-in and unplug process of the server node, it is helpful to reduce the friction between the server node and the cabinet.

[0010] In one possible implementation, the node base plate is provided with a first groove, and the rolling element is at least partially located in the first groove; and / or the bracket is provided with a second groove, and the rolling element is at least partially located in the second groove. In this case, the rolling element can be partially accommodated in the first groove and / or the second groove, and the rolling element has little effect on the height dimension design between adjacent ones. In addition, the second groove plays a guiding role during the plugging and unplugging of the server node to prevent the server node from being offset.

[0011] In the second aspect, the present application provides a cabinet server. The cabinet server includes a cabinet, a plurality of first magnetic components, at least one server node and a controller; the cabinet includes a cabinet backplane and a plurality of mounting positions, the cabinet backplane is located at the rear end of the plurality of mounting positions, the front end of each mounting position has a mounting port, the first magnetic components are all mounted on the cabinet backplane, and a first magnetic component is provided at the rear end of each mounting position, each first magnetic component is connected to the controller, and each mounting position is used to install the server node. In the process of inserting the server node into the mounting position along the mounting port of the mounting position, the distance sensor located on the server node is used to detect the distance from the cabinet backplane, the server node sends the distance detected by the distance sensor to the controller, and the controller is used to control the first magnetic component in the same mounting position to generate magnetic force when the distance is less than or equal to the first threshold value, and the magnetic force is used to adsorb the second magnetic component located on the server node. That is, the distance sensor is used to detect the distance between the cabinet backplane, and the controller can control the mutual attraction between the first magnetic component and the second magnetic component according to the distance value, so as to realize the automatic insertion and fixation of the server node. This process does not require manual operation, the cabinet server has a high degree of automated management, and the server node fixing method is simple.

[0012] In one possible implementation, the server node includes an out-of-band baseboard management controller, which connects the distance sensor and the controller. In this case, the detection value of the distance sensor located in the server node can be transmitted to the controller through the out-of-band baseboard management controller.

[0013] In the third aspect, the present application provides a control method for a cabinet server. Among them, the cabinet server includes a cabinet, at least one distance sensor, at least one first magnetic component and a controller, and the cabinet includes multiple installation positions, and the installation positions are used to install server nodes. The method includes: the controller obtains the detection value of the distance sensor, and the detection value is used to represent the distance of the server node detected by the distance sensor from the same installation position. If the detection value is within the first range, the first magnetic component located at the same installation position is controlled to generate a first magnetic force, and the first magnetic force is used to adsorb the second magnetic component located at the server node. This method can determine whether the server node is inserted through the distance sensor, and after the first current is passed through the first magnetic component, a first magnetic field is generated to achieve attraction of the second magnetic component, thereby achieving adsorption and fixation of the cabinet to the server node. This process does not require manual operation, and the process is simple and easy to implement.

[0014] In one possible implementation, the method further includes: in response to the instruction, the controller controls the first magnetic component located at the same installation position to generate a second magnetic force, and the second magnetic force is used to repel the second magnetic component located on the server node. With this method, the server node can be unlocked and automatically pushed out without manual operation, and the operation process is simple.

[0015] In the present application, the cabinet can automatically adsorb and lock the server node through the attraction between the first magnetic component and the second magnetic component to assist the installer in installation, which is conducive to reducing the difficulty of operation and maintenance of the cabinet server. In addition, by utilizing the repulsion between the first magnetic component and the second magnetic component, the user can complete the unlocking and pushing out process of the server node through remote operation, which is conducive to reducing the difficulty of operation and maintenance of the cabinet server. In addition, the server node is also provided with a rolling member, which can reduce the friction resistance received by the server node during the plug-in and unplugging process, which is conducive to reducing the difficulty of plug-in and unplugging the server node.

In order to better illustrate the structure, Figure 2 The server node is omitted.

[0030] In some embodiments, the cabinet server 10 may include a cabinet 1 and multiple server nodes 2. The cabinet 1 has multiple installation positions 16. Each server node 2 can be detachably installed in an installation position of the cabinet 1. The server node may include but is not limited to a rack cabinet server, a blade cabinet server, or a tower cabinet server. In some optional embodiments, a switch may also be installed in the cabinet 1 of the cabinet server 10. In this embodiment, the installation of multiple server nodes 2 in the cabinet 1 is taken as an example for description.

[0031] Exemplarily, the cabinet 1 includes a cabinet top plate 11, a cabinet bottom plate 12, two cabinet side plates 13, and a cabinet back plate 14. The cabinet top plate 11 is arranged opposite to the cabinet bottom plate 12, the two cabinet side plates 13 are arranged opposite to each other and are located between the cabinet top plate 11 and the cabinet bottom plate 12, and the cabinet back plate 14 is located between the cabinet top plate 11 and the cabinet bottom plate 12 and connects the two cabinet side plates. The cabinet top plate 11, the cabinet bottom plate 12, the cabinet side plates 13, and the cabinet back plate 14 together form an installation position 16 of the cabinet 1. In the embodiment of the present application, the direction from the cabinet bottom plate 12 to the cabinet top plate 11 is defined as the height direction of the cabinet 1, the direction from one cabinet side panel 13 to another cabinet side panel 13 is the width direction of the cabinet 1, and the depth direction of the cabinet 1 is perpendicular to the height direction of the cabinet 1 and perpendicular to the width direction of the cabinet 1; the rear end of the installation position 16 is defined as the end close to the cabinet back panel 14, and the front end of the installation position 16 is defined as the end away from the cabinet back panel.

[0032] Among them, the cabinet 1 can be a cabinet of a whole cabinet server, the width of the cabinet 1 can be 19 inches or the width in other protocols, and the height of the cabinet 1 can be 22U, 32U, 42U or other sizes. In the server, U is the basic unit of server thickness and 1U=4.45cm. In some other embodiments, the cabinet 1 can also be a cabinet of a cabinet-type server, and the size of the cabinet 1 is not strictly limited and can be selected according to actual design requirements.

[0033] Exemplarily, the cabinet back plate 14 connects the cabinet top plate 11 and the cabinet bottom plate 12, wherein the cabinet back plate 14 is a structural plate, and the cabinet back plate 14 may be provided with a plurality of connection holes and / or grooves and / or protrusions for fixing other components. Exemplarily, the cabinet 1 may also include a plurality of brackets 15, and the plurality of brackets 15 are installed in the internal space of the cabinet 1 and are arranged at intervals along the height direction of the cabinet 1. The plurality of brackets 15 may divide the installation space of the cabinet 1 into a plurality of installation positions 16. At this time, the plurality of installation positions 16 are all located on one side of the cabinet back plate 14.

[0034] Among them, the two opposite sides of the bracket 15 are fixedly connected to the two cabinet side panels 13 respectively. The other side of the bracket 15 can also be fixedly connected to the cabinet back panel 14. For example, the bracket 15 may include two sections of support plates 151. The two sections of support plates 151 are arranged at intervals, and the two sections of support plates 151 are respectively fixedly connected to the cabinet side panels 13 on both sides of the cabinet 1 and extend along the depth direction of the cabinet 1. At this time, the volume occupied by the bracket 15 is small, and the weight of the bracket 15 is light, which is conducive to reducing the material of the bracket 15 and reducing the weight of the cabinet 1. At the same time, the adjacent parts in the installation position 16 are interconnected, and the air circulation in the cabinet 1 is good. In some other embodiments, the bracket 15 can also be a whole support plate, and the support plate supports two cabinet side panels 13. At this time, the structural strength of the bracket 15 is high and the stability is good, which is conducive to improving the supporting strength of the bracket 15.

[0035] In some embodiments, the cabinet server 10 may further include a cabinet management board component 3 , a first connecting member 4 , a magnetic circuit control component 5 , and a U-position management board component 6 .

[0036] Exemplarily, the cabinet management board assembly 3 may include a cabinet management board 31 and at least one controller 32, and at least one controller 32 is installed on the cabinet management board 31. A plurality of circuits may be provided on the cabinet management board 31. The controller 32 is electrically connected to other components through the circuit. Among them, the cabinet management board 31 may be installed on the side of the cabinet back plate 14 facing away from the installation position 16. In some other embodiments, the cabinet management board 31 may also be installed on the cabinet top plate 11, the cabinet bottom plate 12 or one of the installation positions 16. The present application does not strictly limit the specific installation position of the cabinet management board 31.

[0037] Exemplarily, there may be a plurality of first connectors 4, and the plurality of first connectors 4 are arranged in one-to-one correspondence with the plurality of mounting positions 16. For example, the first connector 4 may be arranged on a surface of the cabinet back panel 14 facing the mounting position 16 and fixedly connected to the cabinet back panel 14. The first connector 4 is electrically connected to the cabinet management board 31. It is understood that in some other embodiments, the first connector 4 may be partially or completely embedded in the cabinet back panel 14 to improve the connection stability between the cabinet management board 31 and the first connector 4.

[0038] Exemplarily, there may be multiple magnetic circuit control components 5 , and the multiple magnetic circuit control components 5 are arranged in a one-to-one correspondence with the multiple installation positions 16 , and the multiple magnetic circuit control components 5 can all be fixed on the cabinet back panel 14 .

[0039] Wherein, each magnetic circuit control component 5 may include a first magnetic component 51 and an electromagnetic control board 52. Exemplarily, there may be multiple electromagnetic control boards 52, and multiple electromagnetic control boards 52 may be fixed on the cabinet back panel 14. For example, multiple electromagnetic control boards 52 may be installed on the side of the cabinet back panel 14 facing the mounting position 16. Multiple electromagnetic control boards 52 may be arranged at intervals along the width direction of the cabinet 1 and symmetrically arranged about the center line 141 of the cabinet back panel 14. It should be noted that in the present application, the center line 141 refers to the line connecting the midpoint of the top end of the cabinet back panel 14 and the midpoint of the bottom end of the cabinet back panel 14. Multiple electromagnetic control boards 52 may also be located at the same height of the cabinet back panel 14.

[0040] The first magnetic component 51 may include a plurality of electromagnets, which may be arranged at the mounting position 16 and mounted one by one on the plurality of electromagnetic control boards 52. That is, the plurality of electromagnets are symmetrically arranged about the center line 141 of the cabinet back plate 14 and are located at the same height of the cabinet back plate 14. The electromagnetic control board 52 is also electrically connected to the cabinet management board 31 to enable the controller 32 to control the electromagnetic control board 52. The electromagnetic control board 52 may also be provided with an electromagnetic drive circuit, which is electrically connected to the electromagnet. That is, the controller 32 arranged on the cabinet management board 31 may control the magnetic magnitude and magnetic pole direction of the electromagnet through the electromagnetic drive circuit.

[0041] It is understandable that the multiple electromagnetic control boards 52 may also be arranged in a ring shape, arranged at intervals along the height direction of the cabinet 1, or arranged in other ways. The present application does not strictly limit the arrangement of the electromagnetic control boards 52, that is, the present application does not strictly limit the arrangement of the first magnetic components 51. Those skilled in the art may change the arrangement of the electromagnetic control boards 52 according to specific design requirements.

[0042] In some other embodiments, in each magnetic circuit control component 5, the first magnetic component 51 may include multiple electromagnets, and the electromagnetic control board 52 is only one piece. The electromagnetic control board 52 is installed on the cabinet back plate 14, and multiple electromagnets are arranged at intervals on the electromagnetic control board 52, which is conducive to reducing the difficulty of installing the electromagnetic control board 52. Of course, in some other embodiments, in each magnetic circuit control component 5, the first magnetic component 51 may include one electromagnet, and the electromagnetic control board 52 is one piece, so as to reduce the number of electromagnets, reduce costs, and reduce the weight of the cabinet server 10.

[0043] Exemplarily, the U-position management board assembly 6 may include a plurality of U-position management boards 61, and the plurality of U-position management boards 61 are arranged in a one-to-one correspondence with the plurality of mounting positions 16, and the plurality of U-position management boards 61 may be fixed on the cabinet backplane 14. The U-position management board 61 is arranged at intervals from the electromagnetic control board 52, and the U-position management board 61 is electrically connected to the cabinet management board 31. The U-position management board assembly 6 may be used to transmit asset information in the cabinet 1, for example, it may be used to transmit location information, weight information, temperature information, etc. of each server node 2. For example, the U-position management board assembly 6 of the cabinet server 10 may also include a plurality of distance sensors 62, and the plurality of distance sensors 62 may be arranged at the mounting position 16, and may be installed in a one-to-one correspondence with the plurality of U-position management boards 61. The plurality of distance sensors 62 are used to detect the distance between the server node 2 and the distance sensor 62. Among them, the distance sensor 62 may be an infrared photoelectric distance sensor 62, a laser photoelectric distance sensor 62, or other types of distance sensors 62.

[0044] Please refer to Figure 3 , Figure 4 and Figure 5 , Figure 3 yes Figure 1 The structural diagram of the server node shown in FIG. Figure 4 yes Figure 3 The schematic diagram of the partial structure of the server node at another angle is shown. Figure 5 yes Figure 3 The schematic diagram of the partial structure of the server node shown in another angle. Figure 3 Corresponding to the main view of the server node, Figure 4 Corresponding to the side view of the server node, Figure 5 Corresponds to the top view of the server node.

[0045] In some embodiments, the server node 2 may include a housing 21, an internal component 22, a second connector 23, and a second magnetic component 24. An installation space 25 may be formed inside the housing 21, and the internal component 22, the second connector 23, and the second magnetic component 24 are all installed in the installation space 25. The height of the housing 21 may be 1U, 2U, or other U-position heights. That is, the server node 2 may be a 1U server node 2, or a 2U or other U-position server node 2.

[0046] Exemplarily, the housing 21 may include a node backplane 211, and the installation space 25 is formed on one side of the node backplane 211. The housing 21 of the server node 2 may also include a node bottom plate 212. The node bottom plate 212 is fixedly connected to the bottom of the node backplane 211. The node bottom plate 212 is used to fix and support the internal components 22 of the server node 2.

[0047] Exemplarily, the second connector 23 may be fixed on the node backplane 211, and the second connector 23 is electrically connected to the internal component 22. The second connector 23 may realize electrical connection between the internal component 22 of the rack server 10 and the external structure.

[0048] Exemplarily, the internal components 22 may include a processor, a memory bar, a circuit board, a heat sink, etc. The present application does not strictly limit the internal structure of the server node 2.

[0049] Exemplarily, the second magnetic component 24 can be fixed on the node backplane 211. The second magnetic component 24 can include multiple permanent magnets, and the multiple permanent magnets can be arranged at intervals. The multiple permanent magnets can also be located at the same height plane of the server node 2. It is understandable that in some other embodiments, the second magnetic component 24 can also be partially or completely embedded in the node backplane 211 to avoid occupying the volume of the installation space 25.

[0050] In some embodiments, the server node 2 may further include a rolling member 26, which may be installed on the node base plate 212. The rolling member 26 is rotatably connected to the server node 2. For example, the node base plate 212 may be provided with a first groove 2121, the first groove 2121 is recessed toward the installation space 25, and the rolling member 26 is at least partially located in the first groove 2121. At this time, the height of the portion of the rolling member 26 exposed from the housing 21 is relatively small, and the height dimension of the server node 2 is relatively small.

[0051] Exemplarily, the rolling element 26 can be two groups, and the two groups of rolling elements 26 are respectively arranged on both sides of the node base plate 212 in the width direction, and each group of rolling elements 26 can include a plurality of spherical balls, and the plurality of spherical balls are arranged in a row at intervals along the depth direction. Of course, in some other embodiments, the plurality of spherical balls of each group of rolling elements 26 can also be arranged in multiple rows along the depth direction. It is understandable that the rolling element 26 can also be a cylindrical roller to increase the load-bearing capacity of the rolling element 26. That is, the embodiment of the present application does not strictly limit the specific structure of the rolling element 26, and those skilled in the art can make a choice according to design requirements.

[0052] Please refer to Figures 1 to 3 , multiple server nodes 2 can be installed in the installation position 16 in a one-to-one correspondence. Multiple server nodes 2 can be inserted / pulled out of the installation position 16 through the installation port located at the front end of the installation position 16, that is, the plug-in and pull-out direction of the server node 2 is parallel to the depth direction of the cabinet 1. Among them, the node backplane 211 is arranged toward the cabinet backplane 14, and the node bottom plate 212 is arranged toward the bracket 15.

[0053] Exemplarily, the first magnetic component 51 located at the same installation position 16 can be set corresponding to the second magnetic component 24 of the server node 2. Since the first magnetic component 51 includes an electromagnet and the second magnetic component 24 includes a permanent magnet, when the first magnetic component 51 is powered on, the first magnetic component 51 can generate a magnetic field, and the second magnetic component 24 will be affected by the magnetic force in the magnetic field. At this time, because the first magnetic component 51 and the second magnetic component 24 are set correspondingly, the interaction between the first magnetic component 51 and the second magnetic component 24 is relatively large. For example, the first magnetic component 51 can pass a first current and generate a first magnetic field, and the second magnetic component 24 will be affected by the first magnetic force from the first magnetic component 51 in the first magnetic field, and under the action of the first magnetic force, the first magnetic component 51 will attract the second magnetic component 24; the first magnetic component 51 can pass a second current and generate a second magnetic field, and the second magnetic component 24 will be affected by the second magnetic force from the first magnetic component 51 in the second magnetic field, and under the action of the second magnetic force, the first magnetic component 51 will repel the second magnetic component 24. That is, when the first magnetic component 51 is powered by the first current, the cabinet backplane 14 will attract the server node 2; when the first magnetic component 51 is powered by the second current, the cabinet backplane 14 will repel the server node 2. When the first magnetic component 51 is not powered, the first magnetic component 51 will not generate a magnetic field, and no interaction force will be generated between the first magnetic component 51 and the second magnetic component 24.

[0054] In addition, since the node backplane 211 is arranged toward the cabinet backplane 14, the magnetic force between the first magnetic component 51 and the second magnetic component 24 will be parallel to the plug-in and unplug direction of the server node 2, which is conducive to improving the utilization efficiency of the magnetic force between the first magnetic component 51 and the second magnetic component 24. Moreover, in the embodiment of the present application, since the first magnetic component 51 includes a plurality of electromagnets arranged at intervals, and the second magnetic component 24 includes a plurality of permanent magnets arranged at intervals, the magnetic force between the first magnetic component 51 and the second magnetic component 24 is distributed at intervals, which is conducive to preventing the cabinet 1 and the server node 2 from being subjected to concentrated force, and is conducive to preventing the cabinet backplane 14 and the node backplane 211 from being greatly deformed. In addition, since the plurality of electromagnets of the first magnetic component 51 are also symmetrically arranged about the center line 141 of the cabinet backplane 14, the magnetic force applied to the server node 2 will also be symmetrically distributed about the center line 141, and the force applied to the server node 2 is uniform, which is conducive to ensuring the stability of the movement during the plug-in and unplugging process of the server node.

[0055] It is understandable that in other embodiments, the second magnetic component 24 may include at least one electromagnet, and the attraction or repulsion between the first magnetic component 51 and the second magnetic component 24 may be achieved by simultaneously controlling the magnetic pole directions of the first magnetic component 51 and the second magnetic component 24 .

[0056] Exemplarily, the first connector 4 can be set corresponding to the second connector 23. When the server node 2 is fixed to the cabinet 1, the first connector 4 is electrically connected to the second connector 23, and the server node 2 transmits information to the cabinet management board 31 through the first connector 4 and the second connector 23 to achieve information interaction.

[0057] Exemplarily, the node base plate 212 is slidably connected to the bracket 15 at the bottom of the mounting position 16 to achieve a detachable connection between the server node 2 and the cabinet 1. For example, the two groups of rolling members 26 of the server node 2 can contact the two sections of the support plate 151 of the bracket 15 respectively, and the server node 2 can move relative to the cabinet along the extension direction of the support plate 151 (that is, the depth direction of the cabinet 1). Among them, since the server node 2 and the bracket 15 of the cabinet are connected by the rolling member 26, the friction force when the cabinet server 10 and the cabinet 1 move relative to each other is small. When the server node 2 is inserted or pushed out, the server node 2 is subject to small resistance. In addition, since the rolling member 26 is at least partially located in the first groove 2121, when the server node 2 is installed in the mounting position 16, the distance between the node base plate 212 and the bracket 15 in the height direction of the cabinet 1 is small or there is no gap, and the rolling member 26 has little effect on the height dimension design between adjacent brackets 15.

[0058] In some other embodiments, the bracket 15 may also be provided with a second groove, and the second groove may extend along the depth direction of the cabinet 1. When the server node 2 is slidably connected to the cabinet 1, the rolling element is at least partially located in the second groove. At this time, the distance between the node base plate 212 and the bracket 15 in the height direction of the cabinet 1 is small or there is no gap, and the rolling element 26 has little effect on the height dimension design between adjacent brackets 15. In addition, the second groove also has a guiding function. When the server node 2 is inserted or pushed out, the rolling element 26 can move along the extension direction of the second groove to prevent the server node 2 from being offset.

[0059] The circuit structure of the cabinet server is described as an example below.

[0060] Please refer to Figure 1 and Figure 6 , Figure 6 yes Figure 1 The structural block diagram of the cabinet server is shown.

[0061] In some embodiments, the cabinet management board 31 is provided with the aforementioned controller 32, and the cabinet management board 31 may also be provided with a control circuit 311 and a communication component 7. The cabinet backplane 14 is provided with an electromagnetic control board 52 and a U-position management board 61. The first magnetic component 51 is fixed to the electromagnetic control board 52, the second magnetic component 24 is fixed to the node backplane 211, and the distance sensor 62 is fixed to the U-position management board 61.

[0062] Exemplarily, the control circuit 311 is used to control the working state of the first magnetic component 51. For example, an electromagnetic drive circuit 521 may be provided on the electromagnetic control board 52, and the electromagnetic drive circuit 521 is electrically connected to the first magnetic component 51. The control circuit 311 is electrically connected to the controller 32 and the electromagnetic drive circuit 521, respectively. The control circuit 311 can be converted into the control voltage required by the electromagnetic drive circuit 521 according to the instructions of the controller 32, so as to control the current passing through the first magnetic component to achieve the purpose of controlling the magnetic magnitude and magnetic pole direction of the first magnetic component. In some other embodiments, the electromagnetic drive circuit 521 may also be provided on the cabinet management board 31 to reduce the difficulty of making the electromagnetic control board 52; or, the control circuit 311 may also be provided on the electromagnetic control board 52, and integrated with the electromagnetic drive circuit 521 to form a control module.

[0063] Exemplarily, the communication component 7 may be electrically connected to the controller 32. The communication component 7 may be used to receive remote control instructions and transmit the instructions to the controller 32 to achieve remote control of the cabinet server 10.

[0064] Based on the aforementioned cabinet server 10 , the present application also provides a control method for the cabinet server 10 , which can assist the operator in inserting or pushing out the server node 2 , thereby simplifying the maintenance process of the cabinet server 10 .

[0065] Please also read Figure 1 , Figure 6 as well as Figure 7 , Figure 7 yes Figure 1 The control method of the cabinet server is shown.

[0066] The cabinet server 10 control method provided in the present application may include:

[0067] S101 : The controller 32 obtains the detection value of the distance sensor 62 .

[0068] Among them, the detection value of the distance sensor 62 corresponds to the distance between the cabinet server 10 located at the same installation position and the distance sensor 62 or the cabinet backplane. For example, the distance sensor 62 can be the aforementioned photoelectric distance sensor. The distance sensor 62 can emit light waves of a specified frequency band, and the light waves are reflected when they touch an object. The distance sensor 62 can receive the reflected light waves and record the time. The distance sensor 62 transmits this time to the controller 32. Since the distance sensor 62 is installed on the cabinet backplane 14, this time corresponds to the distance between the cabinet backplane 14 and the node backplane 211. For example, the longer this time is, the longer the distance between the cabinet backplane 14 and the node backplane 211 is; the shorter this time is, the shorter the distance between the cabinet backplane 14 and the node backplane 211 is. After the controller 32 obtains the detection value of the distance sensor 62, it can judge the detection value and generate corresponding instructions.

[0069] S102 , if the detection value is within the first range, the controller 32 can control the first magnetic component 51 to generate a first magnetic force, and the first magnetic force is used to attract the second magnetic component 24 located on the server node 2 to make the server node 2 close to and fixed to the cabinet backplane 14 .

[0070] Specifically, after determining that the detection value is within the first range, the controller 32 can generate a first control instruction. The first control instruction can be converted into a corresponding control voltage by the control circuit 311 and transmitted to the electromagnetic drive circuit 521. The electromagnetic drive circuit 521 generates a first current under the control voltage, and the first magnetic component 51 generates a first magnetic field after the first current is passed. Under the action of the first magnetic field, the first magnetic component 51 attracts the second magnetic component 24. For example, the polarity of the side of the second magnetic component 24 facing the first magnetic component 51 can be an S pole. After the first magnetic component 51 passes the first current, the polarity of the side of the first magnetic component 51 facing the second magnetic component 24 can be an N pole. The first magnetic force of the first magnetic component 51 on the second magnetic component 24 can attract the second magnetic component 24. That is, the server node 2 will be attracted by the cabinet backplane 14 and approach the cabinet backplane 14, and will eventually be fixed on the cabinet backplane 14 under the action of the magnetic force. Under this control method, in the process of inserting the server node 2 into the installation position 16 along the installation opening of the installation position 16, the installer only needs to partially insert the server node 2 into the installation position 16, and the cabinet server 10 can automatically achieve the adsorption and locking of the server node 2. That is, the cabinet server 10 can assist the installer in installing the server node 2. The cabinet server 10 has high automation management capabilities. In addition, the cabinet 1 can achieve the adsorption and locking of multiple server nodes 2 at the same time, and the installation efficiency of the server node 2 is high. If the controller 32 determines that the detection value is not within the first range, it means that the server node 2 is not inserted into the cabinet, then the electromagnetic drive circuit 521 will not generate current, and the first magnetic component 51 will not generate a magnetic field.

[0071] See also Figure 8 , Figure 8 It is a coordinate relationship diagram of the distance S between the node backplane and the cabinet backplane and the magnetic size F.

[0072] In some embodiments, the distance sensor 62 can continuously monitor, obtain the detection value, and transmit the detection value to the controller 32 to detect in real time the distance S between the cabinet backplane 14 and the node backplane 211. The controller 32 can adjust the magnitude of the first current according to the specific magnitude of the real-time detection value to adjust the magnetic force magnitude F between the first magnetic component 51 and the second magnetic component 24 in real time.

[0073] When the detection value is in the first interval within the first range, as the distance S decreases, the magnitude of the first current can gradually increase, and the magnetic force magnitude F gradually increases. At this time, the server node 2 has just been inserted into the cabinet 1, and the distance S between the cabinet backplane 14 and the node backplane 211 is relatively large, so the magnetic force magnitude F between the first magnetic component 51 and the second magnetic component 24 can be gradually increased, and the acceleration of the server node 2 gradually increases, which is conducive to quickly bringing the server node 2 close to the cabinet backplane 14. For example, when S3≤S≤S4, the magnetic force magnitude F can be in a linear function relationship with the distance S, and when S=S3, F=F1; when S=S4, F=0. It can be understood that in some other embodiments, the magnetic force magnitude F can be in other functional relationships with the distance S, and the two can be negatively correlated.

[0074] When the detection value is in the second interval within the first range, the magnitude of the first current remains unchanged, and the magnetic magnitude F remains unchanged. At this time, the first magnetic component 51 constantly adsorbs the second magnetic component 24, and the speed of the server node 2 is steadily increased. For example, when S2<S<S3, F=F1.

[0075] When the detection value is in the third interval within the first range, as the distance S decreases, the magnitude of the first current can gradually decrease, and the magnitude of the magnetic force F gradually decreases. At this time, the distance between the node backplane 211 and the cabinet backplane 14 is small, and the magnetic force between the first magnetic component 51 and the second magnetic component 24 can be appropriately reduced. When the magnetic force between the first magnetic component 51 and the second magnetic component 24 is less than the sliding friction of the server node 2, the server node 2 can be decelerated to prevent the speed of the server node 2 from being too high, and to prevent the server node 2 from hitting the cabinet backplane 14 at an excessive speed. For example, when S1≤S≤S2, the magnitude of the magnetic force F can be in a linear function relationship with the distance S, and when S=S1, F=F2; when S=S2, F=F1. It can be understood that in some other embodiments, the magnitude of the magnetic force F can be in other functional relationships with the distance S, and the two can be positively correlated.

[0076] When the detection value is in the fourth interval within the first range, the magnitude of the first current remains unchanged, and the magnetic magnitude F remains unchanged. At this time, the server node 2 has been fully inserted into the cabinet 1, and the first magnetic component 51 can continuously attract the second magnetic component 24 to achieve locking and fixing between the server node 2 and the cabinet 1, preventing the server node 2 from being separated from the cabinet 1 under the action of external force. For example, when 0<S<S1, F=F2.

[0077] For example, S1 can be 1 cm, S2 can be 2 cm, S3 can be 3 cm, and S4 can be 10 cm. It should be noted that the specific values ​​of the distance S between the node backplane 211 and the cabinet backplane 14 and the magnetic size F can be adjusted according to other factors such as the size and weight of the server node 2, and this application does not make strict restrictions on this.

[0078] Of course, in some other embodiments, the distance sensor 62 may also be detected at regular intervals. The first control signal of the controller 32 may be continuous. At a certain moment, after the controller 32 obtains the detection value of the distance sensor 62, the controller 32 may judge the distance between the node backplane 211 and the cabinet backplane 14 according to the magnitude of the detection value, and issue a continuous first control signal. Under the effect of the continuous first control signal, the distance S and the magnetic magnitude F between the node backplane 211 and the cabinet backplane 14 can still maintain the aforementioned change relationship. At this time, the energy consumed by the distance sensor 62 is less, which is beneficial to reducing the energy consumption of the cabinet server 10.

[0079] In some embodiments, the cabinet server 10 may further include a communication component 7, which may be installed on the cabinet management board 31. The communication component 7 may be used to receive remote control instructions and transmit the instructions to the controller 32 to implement remote control of the cabinet server 10.

[0080] At this time, the control method of the cabinet server 10 may further include:

[0081] In response to the instruction, the controller 32 controls the first magnetic component 51 to generate a second magnetic field to repel the second magnetic component 24 , so that the server node 2 is away from the cabinet backplane 14 .

[0082] Specifically, the user can send a push command, and the communication component 7 passes it to the controller 32 after receiving the push command. The controller 32 generates a second control command. The second control command can be passed to the electromagnetic drive circuit 521 on the designated installation position 16 through the control circuit 311. After receiving the second control command, the electromagnetic drive circuit 521 can pass a second current to the first magnetic component 51. The direction of the second current is opposite to the direction of the aforementioned first current. The first magnetic component 51 located at the designated installation position 16 generates a second magnetic field after passing the second current. Under the action of the second magnetic field, the first magnetic component 51 located at the designated installation position 16 repels the second magnetic component 24. For example, the polarity of the side of the second magnetic component 24 facing the first magnetic component 51 can be an S pole, and after the first magnetic component 51 passes the second current, the polarity of the side of the first magnetic component 51 facing the second magnetic component 24 can be an S pole, and the first magnetic component 51 can repel the second magnetic component 24. That is, the attraction of the cabinet backplane 14 to the server node 2 will become a repulsive force, and the server node 2 at the designated position will be automatically pushed out. Under this control method, the server node 2 is pushed out in a simple manner, and the cabinet server 10 can complete the push-out operation remotely, which is beneficial to improving the operation and maintenance efficiency of the cabinet server 10. It should be noted that in some embodiments, this step may not be required.

[0083] Exemplarily, after the controller 32 receives the push command, the controller 32 may first obtain the detection value through the distance sensor 62 at the specified position, and the controller 32 determines whether the server node 2 is in the installation state according to the detection value. If it is detected that the server node 2 is in the installation state, the first magnetic component 51 is controlled to generate a second magnetic field; if it is detected that the server node 2 does not meet the installation state, the process is terminated or a corresponding warning message is sent to the user to prompt the user. In some other embodiments, it is also possible to determine whether the server node 2 is in the installation state by whether the first connector and the second connector are connected.

[0084] Exemplarily, the distance sensor 62 can also detect the distance between the cabinet backplane 14 and the node backplane 211 in real time, and transmit the detection value to the controller 32. The controller 32 continuously adjusts the size of the second current according to the size of the detection value, thereby controlling the size of the magnetic force between the first magnetic component 51 and the second magnetic component 24. For example, when the distance between the cabinet backplane 14 and the node backplane 211 is small, the second current can be large to quickly push the server node 2 out. When the distance between the cabinet backplane 14 and the node backplane 211 exceeds a certain value, the controller 32 can also power off the electromagnetic drive circuit 521. At this time, the first magnetic component 51 does not generate a magnetic field, and the server node 2 can be regarded as having been pushed out, which is conducive to saving the energy consumed by the first magnetic component 51. It can be understood that the server node 2 is regarded as being pushed out when the distance between the node backplane 211 of the server node 2 and the cabinet backplane 14 reaches a certain length, not that the server node 2 is completely out of the cabinet 1. In addition, by controlling the size and duration of the second current, the distance at which the server node 2 is pushed out can also be controlled to meet different work requirements.

[0085] It should be noted that in some working states, the user can also send an insertion instruction to the communication component 7. At this time, no matter what the detection value of the distance sensor 62 is, the controller 32 generates a third control instruction after receiving the insertion instruction. The third control instruction can be converted into a corresponding control voltage by the control circuit 311 and transmitted to the electromagnetic drive circuit 521. The electromagnetic drive circuit 521 can also generate a first current under the control voltage. After the first magnetic component 51 passes the first current, it generates a first magnetic field and attracts the second magnetic component 24. This method does not need to consider the detection value of the distance sensor 62. When the distance sensor 62 is damaged, the automatic insertion of the server node 2 can still be achieved. During the operation and maintenance of the cabinet server 10, when the initial insertion distance of the server node 2 is insufficient, the detection of the distance sensor 62 may not be within the first range, and the conditions for the automatic insertion of the server node 2 are not met, the user can insert the server node 2 into the cabinet 1 by this method.

[0086] That is, in the embodiment of the present application, by providing the distance sensor 62, the first magnetic component 51 and the second magnetic component 24, the user can remotely control the cabinet server 10 to achieve automatic insertion, locking or unlocking, and automatic ejection of the server node 2. The entire process does not require manual operation, the cabinet server 10 has a high degree of automation, and the operation and maintenance cost of the cabinet server 10 is low. In addition, the user can complete the locking or unlocking operation of the server node 2 without tools, which facilitates the operation and maintenance of the server node 2.

[0087] See also Fig. 9 , Fig. 9 It is a structural diagram of another cabinet server provided in an embodiment of the present application.

[0088] In some embodiments, the cabinet server 10 may include the aforementioned cabinet 1, server node 2, cabinet management board assembly 3, first connecting part 4, magnetic circuit control assembly 5, U-position management board assembly 6, and may also include a vacuum suction cup 8. Only the vacuum suction cup 8 is described below, and the remaining structures can refer to the aforementioned embodiments, and no further details will be given here.

[0089] Exemplarily, there may be multiple vacuum suction cups 8, which are installed in the installation position 16 one by one and fixedly connected to the cabinet back plate 14. The vacuum suction cup 8 can be used to absorb the server node 2. For example, when the distance sensor 62 detects that the server node 2 has been fully inserted into the cabinet 1, the node back plate 211 is close to the vacuum suction cup 8. At this time, the controller 32 can issue a third control instruction. The third control instruction can make the first magnetic component 51 (see Figure 2 ) is powered off, and the vacuum device (not shown) is used to exhaust the air in the vacuum suction cup 8, so that negative air pressure is generated in the suction cup. Under the action of atmospheric pressure, the back panel of the server node 2 is sucked and locked. When the server node 2 needs to be pushed out, the second control instruction generated by the controller 32 can first inflate the corresponding vacuum suction cup 8 through the vacuum device, so that the vacuum suction cup 8 is separated from the cabinet back panel 14. Then the first magnetic component 51 is passed through the second current to push the server node 2 out.

[0090] That is, in this embodiment, by providing the vacuum suction cup 8, the server node 2 can be locked and unlocked. When the server node 2 is inserted into the cabinet 1, the first magnetic component 51 does not need to be continuously powered, which is beneficial to reducing the energy consumption of the cabinet server 10 and alleviating the heat dissipation burden of the cabinet server 10.

[0091] See also Fig.10 , Fig.10 This is a structural diagram of another cabinet server provided in an embodiment of the present application.

[0092] In some embodiments, the distance sensor 62 can be installed on the bracket 15 of the cabinet 1 and arranged close to the cabinet back plate 14. At this time, the detection value of the distance sensor 62 corresponds to the distance between the distance sensor 62 and the detected object in the height direction of the cabinet 1. Other structures of the cabinet server 10 can refer to the above embodiments, and will not be described in detail here.

[0093] For example, when the server node 2 is not inserted into the cabinet 1, the detection value of the distance sensor 62 is large, and the value detected by the distance sensor 62 is the distance between adjacent brackets 15. At this time, the first magnetic component 51 is in a power-off state, and the first magnetic component 51 does not consume energy. When the server node 2 is inserted into the cabinet 1, the detection value of the distance sensor 62 is small, and the value detected by the distance sensor 62 is the distance between the distance sensor 62 and the node base plate 212. At this time, the controller 32 can generate a first control instruction, the first magnetic component 51 generates a first current, the first magnetic component 51 generates a first magnetic field and attracts the second magnetic component 24 (such as Figure 3 As shown in FIG. 1 , the cabinet server 10 is locked and fixed to the cabinet back panel 14. When the user needs to push out the server node 2, the controller 32 can first generate a second control instruction to make the first magnetic component 51 generate a second current, the first magnetic component 51 repels the second magnetic component 24, and the cabinet server 10 is pushed out. At this time, if the detection value of the distance sensor 62 becomes larger, it means that the server node 2 has been pushed out, and the controller 32 can power off the first magnetic component 51 to save power consumption and reduce heat generation.

[0094] See also Fig.11 , Fig.11 This is a structural diagram of another cabinet server provided in an embodiment of the present application.

[0095] In some embodiments, the distance sensor 62 may also be installed on the node backplane 211 of the server node 2. At this time, the detection value of the distance sensor 62 corresponds to the distance between the distance sensor 62 and the cabinet backplane 14. When the distance between the distance sensor 62 and the cabinet backplane 14 is within the first range, the controller 32 may control the first magnetic component 51 to generate a first magnetic force, and the first magnetic component 51 adsorbs the second magnetic component 24 (such as Figure 3 shown).

[0096] Exemplarily, the server node 2 may also include an out-of-band substrate management controller, which connects the distance sensor 62 and the controller 32. The server node 2 sends the distance detected by the distance sensor 62 to the controller 32. The controller 32 may obtain the detection value of the distance sensor 62 through the out-of-band substrate management controller to control the magnetic magnitude and magnetic direction of the first magnetic component. For example, when the server node is inserted into the mounting position 16 along the mounting opening of the mounting position 16, the out-of-band substrate management controller may be first connected to the controller 32, such as by wired connection or wireless connection, and then the server node 2 may be automatically adsorbed and locked by the magnetic force between the first magnetic component 51 and the second magnetic component 24.

[0097] It is understandable that, in some other embodiments, the server node 2 may further include other remote signal transmission structures, and the cabinet 1 is provided with a corresponding remote signal receiving structure to realize the transmission of the detection value of the distance sensor 62 .

[0098] The above are only specific embodiments of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
