Description

Technical Field

[0001] This invention relates to the field of server technology, and more specifically, to a server deformation correction device and correction method. Background Technology

[0002] When servers operate in a rack for extended periods, the baseplate undergoes slow plastic deformation due to factors such as gravity, vibration, temperature changes, and rack installation misalignment. This deformation can create gaps between the CPU and the socket, leading to poor contact and subsequently causing memory errors, incomplete capacity recognition, or frequent crashes. Mild cases result in frequency throttling and lag, while severe cases can crack the internal PCB circuitry, causing short circuits, burns, or even fires. However, current solutions for server baseplate deformation have fundamental flaws in their corrective mechanisms, remaining reliant on shutdown and rack removal.

[0003] In related technologies, the correction operation of the server baseplate is based on the premise that the server is removed from the rack and offline. Correspondingly, the deformation detection scheme is also limited to offline or post-event nature. The baseplate deformation detection device usually needs to be manually disassembled when the server is stopped. This means that the baseplate deformation problem can only be dealt with after it has deteriorated to the point of causing a failure and shutdown. It cannot be contained in time during normal server operation, resulting in high maintenance costs and business continuity cannot be guaranteed. Summary of the Invention

[0004] This invention provides a server deformation correction device to at least solve the problems in related technologies, such as the need for offline operation and maintenance of servers and high labor costs for operation and maintenance.

[0005] According to an embodiment of the present invention, a server deformation correction device includes: a detection component installed in a server rack, the detection component being used to detect the deformation parameters of the server's base plate; and a correction component installed in the rack and located below the base plate, the correction component being communicatively connected to the detection component, the correction component being used to support the deformation area of ​​the base plate according to the base plate deformation parameters.

[0006] The present invention also provides a server deformation correction method, which is used in the above-mentioned server deformation correction device. The server deformation correction method includes: controlling a detection component to detect the deformation parameters of the server's base plate; and controlling the deformation area of ​​the correction component corresponding to the support base plate according to the base plate deformation parameters.

[0007] Through this invention, the correction component can obtain the deformation parameters of the base plate through the detection component, and automatically correct the base plate according to the deformation area of ​​the base plate corresponding to the deformation parameters, so as to ensure the stable and reliable operation of the server. At the same time, there is no need to remove the server from the rack during the correction process. The server can be located in the rack and always online, so as to achieve automatic operation and maintenance without downtime and reduce the labor cost of operation and maintenance.

[0013] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] Reference Figures 1-5 As shown, a server deformation correction device according to a first aspect embodiment of the present invention includes: a detection component 1 and a correction component 2. The detection component 1 is installed in a cabinet 30 having a server 20 and is used to detect the deformation parameters of the base plate of the server 20. The correction component 2 is installed in the cabinet 30 and located below the base plate 201. The correction component 2 is communicatively connected to the detection component 1 and is used to support the deformation area of ​​the base plate 201 according to the base plate deformation parameters.

[0015] The server deformation correction device can be installed inside the rack 30, which houses one or more servers 20. For example, the rack 30 can have multiple server 20 mounting positions. Each server 20 mounting position is equipped with a left guide rail 301 and a right guide rail 302. The left guide rail 301 and the right guide rail 302 extend along the X direction, which can be the front-to-back direction. The left guide rail 301 and the right guide rail 302 are spaced apart in the Y direction, which can be the left-to-right direction. The multiple server 20 mounting positions are spaced apart in the Z direction, which can be the up-to-down direction. The server 20 can be inserted into the corresponding server 20 mounting position in the rack 30 along the extension direction of the left guide rail 301 and the right guide rail 302. At this time, the length direction of the server 20 is the X direction, the width direction of the server 20 is the Y direction, and the height direction of the server 20 is the Z direction. The base plate 201 of the server 20 overlaps with the left guide rail 301 and the right guide rail 302 at both ends in the Y direction.

[0016] When the server 20 is running, the detection component 1 can detect the deformation parameters of the server 20 base plate 201 in real time, and the correction component 2 can support the deformed area of ​​the server 20 base plate 201 to achieve automatic correction of the server 20 base plate 201. The correction process does not require manual intervention. At the same time, the entire adjustment process does not require the server 20 to be taken off the rack or shut down, which can achieve zero downtime operation and maintenance.

[0017] Specifically, the server deformation correction device includes a detection component 1 and a correction component 2. The detection component 1 is installed in the rack 30 containing the server 20. The detection component 1 can detect the deformation parameters of the base plate of the server 20 through methods such as grating array detection, three-dimensional digital image detection, and distributed fiber optic sensing. The base plate deformation parameters reflect the deformation of the base plate 201 of the server 20. The detection principle of the detection component 1 for the base plate deformation parameters is not limited to this, as long as it can detect the base plate deformation parameters.

[0018] The correction component 2 is installed inside the rack 30 and located below the base plate 201. The correction component 2 is communicatively connected to the detection component 1. The correction component 2 can obtain the base plate deformation parameters through the detection component 1, and then correct the deformation of the base plate 201 of the server 20 according to the deformation parameters of the base plate supporting the deformation area. This keeps the base plate 201 as flat as possible, so as to avoid the base plate 201 from continuously and slowly deforming downwards, preventing gaps between the CPU and the socket inside the server 20, and reducing the risks of poor CPU contact, memory errors, incomplete capacity recognition, or frequent crashes.

[0019] According to the server deformation correction device of the present invention, the correction component 2 can obtain the deformation parameters of the base plate through the detection component 1, and automatically correct the deformation area of ​​the support base plate 201 according to the deformation parameters of the base plate, so as to ensure the stable and reliable operation of the server 20. At the same time, during the correction process, there is no need to remove the server 20 from the rack 30. The server 20 can be located in the rack 30 and always online, so as to realize automatic operation and maintenance without downtime and reduce the labor cost of operation and maintenance.

[0020] In some embodiments of the present invention, reference is made to... Figure 3 and Figure 4 As shown, the detection component 1 includes: multiple grating beam-beam units, which are distributed at different positions below the base plate 201 and fixedly connected to the cabinet 30. Each grating beam-beam unit includes: a transmitter 11 and a receiver arranged opposite to each other. The transmitter 11 is used to emit a laser beam 12, and the receiver is used to receive the laser beam 12 and determine the deformation parameters of the base plate according to the light intensity of the laser beam 12.

[0021] The detection component 1 includes multiple grating beam units, which can form a grating array. When the base plate 201 of the server 20 deforms downward in the Z direction, it will block the corresponding laser beam 12, thus weakening the intensity of the laser beam 12. By pre-calibrating the intensity of the laser beam 12 and the downward deformation of the base plate 201, the deformation amount and deformation area of ​​the base plate 201 can be deduced from the position of the grating beam units. At the same time, by controlling the sampling period of the grating beam units, the deformation parameters of the base plate 201, such as the deformation rate and deformation acceleration, can also be obtained.

[0022] Specifically, the grating beam-through unit can be arranged inside the cabinet 30 and adjacent to the base plate 201 to facilitate the detection of minute deformations of the base plate 201. The transmitter 11 can emit a collimated laser beam 12 to the receiver. When the base plate 201 of the server 20 undergoes a downward deformation, the lower surface of the base plate 201 displaces downward along the direction of gravity (Z direction), and the light-shielding width of the base plate 201 to the laser beam 12 changes. The light intensity distribution received by the receiver changes accordingly. By calibrating the mapping relationship between the change in light-shielding width and the Z-direction displacement of the base plate 201, the vertical displacement value of the base plate 201 in the corresponding section of the grating beam-through unit, i.e., the Z-direction deformation, can be calculated. At the same time, multiple grating beam-through units can be arranged at intervals below the base plate 201. Each grating beam-through unit can detect different areas of the base plate 201. Through multiple grating beam-through units, the center coordinates (X, Y) of the deformed area of ​​the base plate 201 can be determined.

[0023] For example, multiple grating beam-beam units can be divided into two groups, one group arranged at intervals in the X direction and the other group arranged at intervals in the Y direction. Each grating beam-beam unit can determine the downward displacement of the base plate 201 in the Z direction based on the change in the light intensity of the laser beam 12 emitted by the corresponding transmitter 11 received by the receiver, and determine the center coordinates (X, Y) of the deformation area of ​​the base plate 201 based on the position of the grating beam-beam unit itself in the X or Y direction. The correction component 2 supports and corrects the base plate 201 at the corresponding center coordinate position.

[0024] Reference Figure 3 and Figure 4 As shown, in the multiple grating beam units arranged at intervals in the X direction, the transmitter 11 and the receiver can be installed on the lower sidewalls of the left guide rail 301 and the right guide rail 302, respectively, so that the grating beam units are closer to the base plate 201 and the detection accuracy of the grating beam units for deformation of the base plate 201 is improved.

[0025] Multiple grating beam units spaced apart in the Y direction are not shown in the figure. These multiple grating beam units spaced apart in the Y direction can be located at the same Z-direction height as the multiple grating beam units spaced apart in the X direction. The multiple grating beam units spaced apart in the Y direction can be installed at the lower end of the left guide rail 301 and the right guide rail 302 through corresponding brackets, or installed on the inner wall of the cabinet 30.

[0026] It should be noted that after receiving the laser beam 12, the receiver converts the optical signal into an electrical signal, and then converts the electrical signal into a digital signal through an ADC (analog-to-digital converter). The calibration fits the curve Δz = f(Δt), where Δt represents the digital signal parameter converted from the light intensity change received by the receiver, f is the mapping rule obtained through calibration, and Δz represents the Z-axis deformation of the base plate 201. Furthermore, based on the sampling frequency of the grating through-beam unit, the deformation rate, deformation acceleration, and cumulative deformation can also be obtained through mathematical calculations.

[0027] In some embodiments of the present invention, the correction component 2 is connected to the detection component 1 via a controller. The controller can control the sampling frequency of the detection component 1, and perform data processing and calculation on the signals collected by the detection component 1 to obtain the corresponding base plate deformation parameters, and control the correction component 2 to support the deformation area of ​​the base plate 201 according to the base plate deformation parameters.

[0028] The base plate deformation parameters may include: deformation area, deformation rate, deformation acceleration, and cumulative deformation. The center coordinates (X, Y) of the deformation area can be determined according to the arrangement of the grating photocells in the X and Y directions. Optionally, the point with the largest cumulative deformation among all trigger condition detection points can be taken as the center coordinates. If multiple adjacent points are triggered, their geometric center (Xc, Yc) is taken. Xc and Yc can be obtained by linear interpolation based on the position of the grating photocells. For the determination of other parameters, please refer to the following formulas: Deformation rate v i (t)=[d i (t)-d i [(t-Δt)] / Δt; Deformation acceleration a i (t)=[v i (t)-v i [(t-Δt)] / Δt; Cumulative deformation D i (t)=d i (t)-d i (0); Where, d i (t) refers to the Z-direction deformation (deflection) of the i-th detection point at time t, that is, the downward deformation of the base plate 201 measured by the grating through-beam unit. For example, d i (t) = 1.2 mm, indicating that the base plate 201 at this point has bent downwards by 1.2 mm compared to its initial state. The measurement principle is that the more the base plate 201 sags, the wider the width of the laser beam 12 is blocked. The displacement value is obtained through calibration and calculation. Δt refers to the sampling time interval, that is, the interval between two adjacent measurements. In this embodiment, it can be 0.1 seconds (10Hz sampling rate), but it can also be set to 1 second, 1 minute, etc., according to actual needs. i (t) refers to the deformation rate, reflecting the deformation speed of the base plate 201. The calculation formula is: v i (t)=[d i (t)-d i The meaning of (t-Δt) / Δt is: the degree of change in the deformation of the base plate in the Z-direction per unit time, reflecting the speed of deformation, and the deformation rate v. i The unit of (t) can be mm / day. For example, v i (t) = 0.03 mm / day, indicating that the point droops by 0.03 mm per day.

[0029] a i (t) refers to the deformation acceleration, i.e., the tendency of deformation to accelerate or decelerate. The calculation formula is: a i (t)=[v i (t)-v i The meaning of (t-Δt) / Δt is: the rate of change of the deformation rate itself. If ai If (t) > 0, it indicates that the deformation is accelerating, and the deformation is getting faster and faster. If a i (t) < 0, indicating that the deformation rate is slowing down. If a i (t)=0 indicates uniform deformation. This can be understood as, at the current deformation rate v... i (t) is not very high, but the deformation acceleration a i If (t)>0, it indicates that the deformation is worsening and early intervention is needed.

[0030] D i (t) refers to the cumulative deformation, i.e., the total creep variable, D i (t)=d i (t)-d i (0) means: the cumulative Z-axis deformation of the base plate 201 from the initial moment (after the server deformation correction device was calibrated) to the current moment. i (0) is the initial reading upon completion of installation, typically 0 or a very small value. The unit is set to millimeters. For example, D. i (t)=1.2mm indicates that the point has sagged by 1.2 millimeters.

[0031] In addition, the controller has multiple preset threshold levels, namely the safety threshold Vsafe, the warning threshold Vwarning, and the preset rate threshold Vaction. The preset rate threshold is also the action threshold, where Vsafe < Vwarning < Vaction. When v i When (t) < Vsafe, it indicates that the deformation rate is less than the safety threshold, and the base plate 201 is in a stable elastic stage, requiring no intervention. When Vsafe ≤ v i When (t) < Vwarning, it indicates that the deformation rate is between the safety threshold and the warning threshold. In this case, a prompt and recording can be made, but the correction component 2 is not forced to operate. When v i (t)≥Vaction, and a i When (t) > 0, it indicates that the deformation rate is greater than the preset rate threshold and the deformation is accelerating. Active correction is immediately triggered, controlling the correction component 2 to support and correct the deformed area of ​​the base plate 201. Optionally, the safety threshold Vsafe is 0.01 mm / day, the warning threshold Vwarning is 0.02 mm / day, and the preset rate threshold Vaction is 0.03 mm / day. Therefore, by monitoring these parameters and comparing them with the preset rate threshold, the server deformation correction device can apply appropriate upward support force to the base plate 201 through the correction component 2 in the early stages of accelerated deformation, preventing the base plate 201 from sagging further.

[0032] When the deformation rate at any detection point exceeds the action threshold and the deformation acceleration is positive, the controller determines that the area has entered the accelerated deformation stage and triggers active correction. Simultaneously, the controller calculates the center coordinates (X, Y) of the deformation area based on the magnitude of the cumulative deformation and the interpolation results of adjacent detection points, and determines the recommended support force F and lifting stroke ΔZ according to a preset support force-deformation mapping table. The support force-deformation mapping table can be calibrated using empirical formulas; for example, the recommended support force F = k... Dmax, where Dmax is the maximum cumulative deformation of the deformation area of ​​the base plate 201 in mm, and k is the proportional coefficient, which can be 4N / mm, with an upper limit of 20N. The recommended lifting stroke ΔZ = Dmax + 0.2mm (interference).

[0033] In some embodiments of the present invention, at least one of the following is satisfied: in the length direction of the base plate 201, the arrangement density of the grating beam-beam unit gradually decreases from the center of the base plate 201 to both sides; in the width direction of the base plate 201, the arrangement density of the grating beam-beam unit gradually decreases from the center of the base plate 201 to both sides.

[0034] Specifically, the length direction of the base plate 201 is Figure 3 In the X-direction of the base plate 201, along its length, the density of the grating beam-through units gradually decreases from the center to both sides. This means that in the front-to-back direction, the grating beam-through units employ a non-uniform strategy of increasing density in the middle and decreasing density at both ends. The denser middle region (approximately half the length of the base plate 201) corresponds to detecting the deformation parameters of the base plate in the expected large deflection area in the middle of the base plate 201. The spacing between adjacent grating beam-through units can be 50 mm to form a dense array of detection points and improve detection resolution. In the thinned front and rear regions (each occupying approximately 1 / 4 of the length of the base plate 201), the deformation parameters of the base plate in the expected small deflection areas at both ends of the base plate 201 are detected. The spacing between adjacent grating beam-through units can be 100 mm to reduce costs.

[0035] The width direction of the base plate 201 is Figure 3 In the Y direction, along the width of the base plate 201, the arrangement density of the grating through-beam units gradually decreases from the center of the base plate 201 towards both sides. Figure 3(Not shown in the image), meaning that in the left-right direction, the grating-beam unit adopts a non-uniform strategy of central densification and end thinning. The central densification region (which can be approximately half the width of the base plate 201) corresponds to detecting the base plate deformation parameters in the expected large deflection area in the center of the base plate 201. The spacing between adjacent grating-beam units can be 50mm to form a dense array of detection points and improve detection resolution. In the end thinning regions (each occupying approximately 1 / 4 of the width of the base plate 201), the base plate deformation parameters in the expected small deflection areas at the left and right ends of the base plate 201 are detected. The spacing between adjacent grating-beam units can be 100mm to reduce costs.

[0036] In the above embodiments, by arranging the grating beam units in the length and / or width directions of the base plate 201 with varying density, the overall number of grating beam units can be reduced while ensuring the monitoring accuracy of key areas.

[0037] In some embodiments of the present invention, reference is made to... Figure 5 As shown, the correction component 2 includes: a fixing member 21, a moving member 22, and a support member 23. The fixing member 21 is fixedly connected to the cabinet 30. The moving member 22 is movably connected to the fixing member 21. The support member 23 is vertically connected to the moving member 22. Both the moving member 22 and the support member 23 are communicatively connected to the detection component 1. The moving member 22 is used to drive the support member 23 to move relative to the fixing member 21. The support member 23 is used to support the deformation area of ​​the base plate 201.

[0038] Specifically, the fixing member 21 is connected to the cabinet 30 and can serve as the base of the correction component 2. When the support member 23 supports the base plate 201, the fixing member 21 can transfer the load to the cabinet 30. The support member 23 is mounted on the moving member 22, which is movable relative to the fixing member 21. At the same time, both the support member 23 and the moving member 22 are connected to the detection component 1 so that the support member 23 and the moving member 22 can support the deformed area of ​​the base plate 201 according to the deformation parameters of the base plate. That is, the moving member 22 can move the support member 23 to the corresponding area of ​​the base plate 201 where it needs to be supported. Then the support member 23 rises relative to the moving member 22 in the Z direction to support and correct the deformed area of ​​the base plate 201.

[0039] In some embodiments of the present invention, reference is made to... Figures 5-8As shown, the movable member 22 is used to drive the support member 23 to move in the length direction of the base plate 201. The support member 23 includes: a rotating arm 231, a lifting driver 232 and a rotating driver 233. The lifting driver 232 and the rotating driver 233 are connected, and one of them is connected to the rotating arm 231, and the other of them is connected to the movable member 22. The lifting driver 232 is used to drive the rotating arm 231 to rise and fall relative to the movable member 22, and the rotating driver 233 is used to drive the rotating arm 231 to rotate relative to the movable member 22.

[0040] Reference Figures 5-8 As shown, the lifting drive 232 is connected to the moving part 22, and the rotating arm 231 is connected to the lifting drive 232 through the rotating drive 233. When supporting the deformable area of ​​the base plate 201, the moving part 22 first drives the support part 23 to move in the X direction, and stops when the distance between the deformable area of ​​the base plate 201 and the rotation axis of the rotating arm 231 is the rotation radius of the rotating arm 231. Then the rotating drive 233 drives the rotating arm 231 to rotate around the rotation axis parallel to the Z direction until the free end of the rotating arm 231 rotates to directly below the deformable area. Finally, the lifting drive 232 drives the rotating drive 233 and the rotating arm 231 to rise together in the Z direction so that the free end of the rotating arm 231 supports the deformable area of ​​the base plate 201.

[0041] In an embodiment not shown in the figure, the rotary actuator 233 is connected to the movable member 22, and the rotating arm 231 is connected to the rotary actuator 233 via the lifting actuator 232. When supporting the deformable area of ​​the base plate 201, the movable member 22 first drives the support member 23 to move in the X direction, and stops when the distance between the deformable area of ​​the base plate 201 and the rotation axis of the rotating arm 231 is the rotation radius of the rotating arm 231. Then, the rotary actuator 233 drives the rotating arm 231 and the lifting actuator 232 to rotate together around a rotation axis parallel to the Z direction until the free end of the rotating arm 231 rotates to directly below the deformable area. Finally, the lifting actuator 232 drives the rotating arm 231 to rise upward in the Z direction so that the free end of the rotating arm 231 supports the deformable area of ​​the base plate 201.

[0042] It should be noted that the lifting driver 232 can be configured as a ball screw or an electric telescopic rod to achieve lifting in the Z direction, and the rotary driver 233 can be a stepper motor or other rotary drive device.

[0043] In the above embodiment, the rotating arm 231, through a single lateral extension structure, can cover the entire area of ​​the base plate 201 and has panoramic support capability. The rotating arm 231 can selectively support the central area, as well as the edge or corner areas of the base plate 201 by rotation. Through the coordinated movement and rotation of the rotating arm 231, support covering the entire area of ​​the base plate 201 can be achieved. Thus, by setting up a liftable and rotatable rotating arm 231, the hardware complexity of the correction device is reduced, and a globally flexible configuration of the support points is achieved.

[0044] Reference Figure 8 As shown, in a specific embodiment of the present invention, the lifting driver 232 includes: a sleeve 2321, a drive motor 2322, and a lifting nut 2323. The sleeve 2321 is fixedly connected to the moving part 22. The lifting nut 2323 and the drive motor 2322 are both disposed inside the sleeve 2321. The lifting nut 2323 is threadedly engaged with the output shaft of the motor. The lifting nut 2323 is also guidedly engaged with the inner wall of the sleeve 2321 in the Z direction. The rotary driver 233 is fixedly connected to the side of the nut away from the drive motor 2322. The rotary arm 231 is fixedly connected to the rotary driver 233 through a set screw 234. When the drive motor 2322 rotates, it can drive the lifting nut 2323 to rise and fall along the inner wall of the sleeve 2321 in the Z direction, and drive the rotary driver 233 and the rotary arm 231 to rise and fall through the lifting nut 2323. In addition, the rotary driver 233 can drive the rotary arm 231 to rotate.

[0045] In other embodiments of the present invention (not shown in the figures), the movable member 22 is used to drive the support member 23 to move in the length and width directions of the base plate 201. The movable member 22 can move the support member 23 directly below the deformed area. The support member 23 can be lifted upward to correct the deformed area of ​​the base plate 201. The support member 23 can be an electric telescopic rod. The movable member 22 can include a first linear motor and a second linear motor connected vertically. The electric telescopic rod can be installed on the second linear motor. The first linear motor can be connected to the fixing member 21. The first linear motor can drive the second linear motor and the electric telescopic rod thereon to move in the X direction. The second linear motor is used to drive the electric telescopic rod to move in the Y direction so that the electric telescopic rod moves directly below the deformed area. Then the electric telescopic rod extends in the Z direction to lift and correct the deformed area of ​​the base plate 201.

[0046] It should be noted that the specific implementation of the correction component 2 is not limited to this. The correction component 2 can also be constructed as a three-axis robotic arm or other movable and lifting device.

[0047] In other embodiments of the present invention, reference is made to Figure 9As shown, the movable member 22 is used to drive the support member 23 to move in the length direction of the base plate 201. The support member 23 includes: a rotating arm 231, a lifting driver 232 and a rotating driver 233. The rotating arm 231 is telescopic in its length direction. One end of the rotating arm 231 is connected to the movable member 22 through the rotating driver 233. The rotating driver 233 is used to drive the rotating arm 231 to rotate relative to the movable member 22. The other end of the rotating arm 231 selectively supports the deformation area of ​​the base plate 201 through the lifting driver 232. The lifting driver 232 is telescopic in the thickness direction of the base plate 201. There are multiple support members 23, and the multiple support members 23 are stacked in the thickness direction of the base plate 201.

[0048] Specifically, the lifting driver 232 and the rotating driver 233 are installed at both ends of the rotating arm 231. The rotating driver 233 can drive the rotating arm 231 to rotate relative to the moving member 22 around a rotation axis parallel to the Z direction. The lifting driver 232 can extend and retract in the Z direction to selectively support the base plate 201. At the same time, the length of the rotating arm 231 is extendable and can be adjusted according to the deformation area of ​​the base plate 201. Multiple support members 23 are stacked in the Z direction, and there can be a Z-direction gap between two adjacent support members 23 to reduce the risk of interference. Meanwhile, the rotating drivers 233 of multiple support members 23 can be arranged around the same rotation axis to save arrangement space.

[0049] When the base plate 201 has multiple deformable areas, the moving member 22 can drive the support member 23 to move in the length direction of the base plate 201 so that each deformable area is within the support range of the support member 23. Then, the rotation driver 233 of each support member 23 drives its respective rotating arm 231 to rotate, and the rotating arm 231 extends and retracts in its length direction so that each deformable area has at least one lifting driver 232 of the support member 23 directly below it in the Z direction. Finally, the lifting driver 232 on the support member 23 extends and rises in the Z direction to support the corresponding deformable area of ​​the base plate 201.

[0050] It should be noted that multiple support members 23 are stacked in the thickness direction of the base plate 201. When the rotating arm 231 rotates and extends, the lifting drive 232 on it can be shortened to its shortest state to avoid interference between the lifting drive 232 and other rotating arms 231, as well as to avoid interference between the lifting drive 232 and the base plate 201.

[0051] In the above embodiment, multiple support members 23 are installed on the moving member 22. When the base plate 201 has multiple deformation areas, each deformation area can be supported by at least one support member 23 to improve the deformation correction effect of the base plate 201.

[0052] In some embodiments of the present invention, reference is made to... Figure 10 As shown, a pressure sensor 235 facing the base plate 201 is provided on the rotating arm 231. When the rotating arm 231 contacts the deformable area of ​​the base plate 201, the pressure sensor 235 can detect the upward supporting force of the rotating arm 231 on the base plate 201, so as to control the output power of the lifting drive 232 according to the recommended supporting force F. When the pressure sensor 235 detects that the pressure it receives is the recommended supporting force F, it can stop the lifting drive 232 and keep it in a locked state to avoid damage to the base plate 201 due to excessive supporting force. Optionally, the pressure sensor 235 is a thin-film pressure sensor, which occupies little space and is easy to arrange.

[0053] In some embodiments of the present invention, the support member 23 further includes a buffer pad 236. The buffer pad 236 may be disposed on the side of the pressure sensor 235 away from the rotating arm 231, or the buffer pad 236 may be disposed between the pressure sensor 235 and the rotating arm 231. When the buffer pad 236 is disposed on the side of the pressure sensor 235 away from the rotating arm 231, the buffer pad 236 is located above the sensor, and the buffer pad 236 prevents the pressure sensor 235 from directly contacting the base plate 201, thereby reducing wear on the pressure sensor 235. (Refer to...) Figure 10 As shown, when the buffer pad 236 is disposed between the pressure sensor 235 and the rotating arm 231, the buffer pad 236 is located below the sensor. The buffer pad 236 can disperse the stress of the pressure sensor 235 when it is subjected to compression, thereby improving the service life of the pressure sensor 235. Optionally, the buffer pad 236 is a polytetrafluoroethylene (PTFE) buffer pad, which has excellent chemical corrosion resistance, electrical insulation, and aging and weather resistance.

[0054] In some embodiments of the present invention, reference is made to... Figure 8 and Figure 10 As shown, the rotating arm 231 can be an L-shaped structure. The rotating arm 231 includes a vertical arm 2311 and a horizontal arm 2312. The vertical arm 2311 and the horizontal arm 2312 are connected at an angle. The vertical arm 2311 can extend along the Z direction. The rotating driver 233 can drive the vertical arm 2311 to rotate around the rotation axis. The horizontal arm 2312 has a fixed end and a free end. The fixed end is fixedly connected to the vertical arm 2311, and the free end can be used to support the deformation area of ​​the base plate 201.

[0055] In the Z direction, the height of the free end of the transverse arm 2312 can be higher than the height of its fixed end. That is, the free end of the transverse arm 2312 is tilted upward. When the rotating arm 231 supports the deformable area of ​​the base plate 201 from bottom to top, the free end of the transverse arm 2312 will first contact the deformable area of ​​the base plate 201, and the fixed end will have a safe distance from the base plate 201. When the transverse arm 2312 is subjected to load and bending deformation, it can be ensured that the fixed end does not contact the base plate 201, so as to avoid the rotating arm 231 from contacting the non-deformable area of ​​the base plate 201.

[0056] In addition, the free end of the transverse arm 2312 can be provided with multiple hollow holes. The hollow holes can avoid the laser beam 12 of the detection component 1, so that the deformation parameters of the base plate can still be detected by the detection component 1 during the support process.

[0057] In some embodiments of the present invention, reference is made to... Figure 5 and Figure 6 As shown, the fixing member 21 includes a first rack 211 and a second rack 212, which are arranged parallel to each other and opposite to each other. The moving member 22 includes a moving part 221, a first gear drive part 222 and a second gear drive part 223. The first gear drive part 222 and the second gear drive part 223 are connected to the two ends of the moving part 221. The first gear drive part 222 meshes with the first rack 211 for transmission, and the second gear drive part 223 meshes with the second rack 212 for transmission. The rotating arm 231 is connected to the moving part 221 through a lifting driver 232 and a rotating driver 233.

[0058] Specifically, both the first rack 211 and the second rack 212 can extend along the X direction. The first rack 211 and the second rack 212 can be directly or indirectly fixedly connected to the inner wall of the cabinet 30. For example, the first rack 211 and the second rack 212 can be fixedly connected to the inner wall of the cabinet 30 through the corresponding rack mounting bracket 213. The first rack 211 can be located directly below the left guide rail 301, and the second rack 212 can be located directly below the right guide rail 302. The first rack 211 and the second rack 212 are parallel.

[0059] The moving part 22 includes a moving part 221, a first gear drive part 222, and a second gear drive part 223. The first gear drive part 222 and the second gear drive part 223 are connected to the two ends of the moving part 221. The first gear drive part 222 meshes with the first rack 211 for transmission, and the second gear drive part 223 meshes with the second rack 212 for transmission. The first gear drive part 222 can drive the moving part 221 to move along the extension direction of the first rack 211, and the second gear drive part 223 can drive the moving part 221 to move along the extension direction of the second rack 212. The first gear drive part 222 and the second gear drive part 223 can work simultaneously and synchronously to ensure the stability and reliability of the moving part 221 in the X direction. The rotating arm 231 is connected to the moving part 221 through a lifting driver 232 and a rotating driver 233 to realize that the rotating arm 231 can be lifted and rotated relative to the moving part 221, and the support member 23 can move with the moving part 221 in the X direction.

[0060] The first gear drive unit 222 may include a servo motor 2221, a drive gear 2222, and multiple driven shafts 2223. The servo motor 2221 is fixedly connected to the moving part 221, and the driven shafts 2223 are rotatably connected to the moving part 221. The servo motor 2221 can be driven to the drive gear 2222 via a reducer to drive the drive gear 2222 to rotate. The drive gear 2222 is connected to the multiple driven shafts 2223 via a belt or chain. The drive gear 2222 can drive the multiple driven shafts 2223 to rotate. Each driven shaft 2223 is provided with a driven gear 2224, which meshes with the first rack 211. The servo motor 2221 can drive the multiple driven shafts 2223 to rotate synchronously via the drive gear 2222, thereby causing the driven gear 2224 to move along the first rack 211 in the X direction, thus realizing the movement of the moving part 221 and ensuring the stability and accuracy of the movement of the moving part 221. The structure of the second gear drive unit 223 is similar to that of the first gear drive unit 222, and will not be described in detail here.

[0061] In some embodiments of the present invention, reference is made to... Figure 5As shown, in the Y direction, the distance between the first rack 211 and the second rack 212 can be equal to the width of the base plate 201. The support member 23 is centrally arranged on the moving part 221, that is, the rotation axis of the rotating arm 231 is located at the center of the moving part 221 in the Y direction. The length of the transverse arm 2312 of the rotating arm 231 is less than or equal to half the distance between the first rack 211 and the second rack 212. The rotating arm 231 can rotate 360 ​​degrees around the rotation axis to facilitate the adjustment of the position of the rotating arm 231, so that the rotating arm 231 can support any position of the base plate 201 and reduce the length of the transverse arm 2312, thereby improving the action efficiency of the correction component 2 during correction. Optionally, the distance between the first rack 211 and the second rack 212 is 200mm, and the length of the transverse arm 2312 of the rotating arm 231 is 100mm.

[0062] According to the server deformation correction device of the present invention, the correction component 2 can obtain the deformation parameters of the base plate through the detection component 1, and automatically correct the base plate 201 according to the deformation area of ​​the support base plate 201 based on the deformation parameters of the base plate. The server 20 does not need to be taken off the rack and shut down to avoid business interruption. It can avoid the economic losses caused by downtime each time hardware intervention is needed, and realize zero downtime operation and maintenance of the data center that runs 24 / 7.

[0063] The correction component 2 can use a grating array for non-contact measurement, which eliminates the signal drift and wear problems of traditional contact sensors after long-term service, and does not apply additional stress interference to the base plate 201 during the measurement process. At the same time, the grating beam unit can be arranged in a non-uniform density to reduce the number of grating beam units while ensuring monitoring accuracy, thus optimizing hardware costs.

[0064] Meanwhile, the detection component 1 can continuously monitor online, and the correction component 2 is movable and can dynamically compensate in real time according to the deformation trend of the base plate 201. It can intervene in the early stage of deformation acceleration, actively intervene in deformation, achieve preventive correction, and reduce the risk of server 20 failure.

[0065] The server deformation correction device can automatically complete the sensing. predict decision making implement The verification loop eliminates the need for manual inspection and calibration, making it suitable for unmanned data centers and robotic maintenance scenarios.

[0066] In addition, the correction component 2 adopts the coordinated action of unidirectional movement of the moving part 22 and lifting and rotating of the support part 23. The support part 23 can traverse any position of the base plate 201, realizing the support coverage of the entire base plate 201. This solution has lower hardware cost, more compact structure, and avoids the problem of motion interference.

[0067] In summary, the server deformation correction device can compensate for the creep of the base plate 201 online, in real time, and dynamically, avoiding a series of secondary failures caused by the sagging of the base plate 201, such as internal motherboard bending, poor heat dissipation, and solder joint fatigue, thus extending the effective service life of the entire server 20.

[0068] According to a second aspect of the present invention, a server deformation correction method is used in the aforementioned server deformation correction apparatus, with reference to... Figure 11 As shown, the server deformation correction method includes: Step S1: Control the deformation parameters of the base plate of the detection component to detect the server.

[0069] Among them, the detection component 1 can detect the deformation parameters of the base plate of the server 20 through methods such as grating array detection, three-dimensional digital image detection, and distributed optical fiber sensing. The base plate deformation parameters reflect the deformation of the base plate 201 of the server 20. The detection principle of the detection component 1 for the base plate deformation parameters is not limited to this, as long as it can detect the base plate deformation parameters.

[0070] Step S2: Control the deformation area of ​​the support base plate corresponding to the correction component according to the base plate deformation parameters.

[0071] The correction component 2 can obtain the deformation parameters of the base plate through the detection component 1, and then correct the deformation of the base plate 201 of the server 20 according to the deformation area of ​​the base plate 201 corresponding to the deformation parameters. This keeps the base plate 201 as flat as possible, so as to avoid the base plate 201 from continuously and slowly deforming downwards, prevent gaps between the CPU and the socket in the server 20, and reduce the risks of poor CPU contact, memory errors, incomplete capacity recognition, or frequent crashes.

[0072] According to the server deformation correction method of the present invention, the correction component 2 can obtain the deformation parameters of the base plate through the detection component 1, and automatically correct the deformation area of ​​the support base plate 201 according to the deformation parameters of the base plate, so as to ensure the stable and reliable operation of the server 20. At the same time, the server 20 does not need to be removed from the rack 30 during the correction process. The server 20 can be located in the rack 30 and always online, so as to realize automatic operation and maintenance without downtime and reduce the labor cost of operation and maintenance.

[0073] In some embodiments of the present invention, the deformation parameters of the base plate include: deformation area, deformation rate, deformation acceleration and cumulative deformation amount. Controlling the deformation area of ​​the support base plate corresponding to the correction component according to the deformation parameters includes: when the deformation rate is greater than or equal to a preset rate threshold and the deformation acceleration is positive, controlling the deformation area of ​​the support base plate corresponding to the correction component, and determining the support force of the correction component on the deformation area according to the cumulative deformation amount.

[0074] During the continuous operation of server 20, detection component 1 can continuously collect vertical displacement data of each detection point on base plate 201 at a sampling frequency of 10Hz. The deformation data at each moment can be recorded as a vector d(t)=[d1(t),d2(t),…,dn(t)], where n is the number of detection points and t is the sampling time. The data is stored in the controller's ring buffer in real time and synchronously transmitted to the BMC (Server Baseboard Management Controller) interface for analysis by the centralized management platform.

[0075] The base plate deformation parameters include: deformation area, deformation rate, deformation acceleration, and cumulative deformation. The center coordinates (X, Y) of the deformation area can be determined according to the arrangement of the grating through-beam units in the X and Y directions. Optionally, the point with the largest cumulative deformation among all trigger condition detection points can be taken as the center coordinates. If multiple adjacent points are triggered, their geometric center (Xc, Yc) is taken. Xc and Yc can be obtained by linear interpolation based on the position of the grating through-beam units. For the determination of other parameters, please refer to the following formulas: Deformation rate v i (t)=[d i (t)-d i [(t-Δt)] / Δt; Deformation acceleration a i (t)=[v i (t)-v i [(t-Δt)] / Δt; Cumulative deformation D i (t)=d i (t)-d i (0); Where, d i (t) refers to the Z-direction deformation (deflection) of the i-th detection point at time t, that is, the downward deformation of the base plate 201 measured by the grating through-beam unit. For example, d i (t) = 1.2 mm, indicating that the base plate 201 at this point has bent downwards by 1.2 mm compared to its initial state. The measurement principle is that the more the base plate 201 sags, the wider the width of the laser beam 12 is blocked. The displacement value is obtained through calibration and calculation. Δt refers to the sampling time interval, that is, the interval between two adjacent measurements. In this embodiment, it can be 0.1 seconds (10Hz sampling rate), but it can also be set to 1 second, 1 minute, etc., according to actual needs. i (t) refers to the deformation rate, reflecting the deformation speed of the base plate 201. The calculation formula is: v i (t)=[d i (t)-d i The meaning of (t-Δt) / Δt is: the degree of change in the deformation of the base plate in the Z-direction per unit time, reflecting the speed of deformation, and the deformation rate v. i The unit of (t) can be mm / day. For example, vi (t) = 0.03 mm / day, indicating that the point droops by 0.03 mm per day.

[0076] a i (t) refers to the deformation acceleration, i.e., the tendency of deformation to accelerate or decelerate. The calculation formula is: a i (t)=[v i (t)-v i The meaning of (t-Δt) / Δt is: the rate of change of the deformation rate itself. If a i If (t) > 0, it indicates that the deformation is accelerating, and the deformation is getting faster and faster. If a i (t) < 0, indicating that the deformation rate is slowing down. If a i (t)=0 indicates uniform deformation. This can be understood as, at the current deformation rate v... i (t) is not very high, but the deformation acceleration a i If (t)>0, it indicates that the deformation is worsening and early intervention is needed.

[0077] D i (t) refers to the cumulative deformation, i.e., the total creep variable, D i (t)=d i (t)-d i (0) means: the cumulative Z-axis deformation of the base plate 201 from the initial moment (after the server deformation correction device was calibrated) to the current moment. i (0) is the initial reading upon completion of installation, typically 0 or a very small value. The unit is set to millimeters. For example, D. i (t)=1.2mm indicates that the point has sagged by 1.2 millimeters.

[0078] In addition, multiple threshold levels can be preset, namely the safety threshold Vsafe, the warning threshold Vwarning, and the preset rate threshold Vaction. The preset rate threshold is also the action threshold, where Vsafe < Vwarning < Vaction. When v i When (t) < Vsafe, it indicates that the deformation rate is less than the safety threshold, and the base plate 201 is in a stable elastic stage, requiring no intervention. When Vsafe ≤ v i When (t) < Vwarning, it indicates that the deformation rate is between the safety threshold and the warning threshold. In this case, a prompt and recording can be made, but the correction component 2 is not forced to operate. When v i (t)≥Vaction, and a iWhen (t) > 0, it indicates that the deformation rate is greater than the preset rate threshold and the deformation is accelerating. Active correction is immediately triggered, controlling the correction component 2 to support and correct the deformed area of ​​the base plate 201. Optionally, the safety threshold Vsafe is 0.01 mm / day, the warning threshold Vwarning is 0.02 mm / day, and the preset rate threshold Vaction is 0.03 mm / day. Therefore, by monitoring these parameters and comparing them with the preset rate threshold, the server deformation correction device can apply appropriate upward support force to the base plate 201 through the correction component 2 in the early stages of accelerated deformation, preventing the base plate 201 from sagging further.

[0079] When the deformation rate at any detection point exceeds the action threshold and the deformation acceleration is positive, the area is determined to have entered the accelerated deformation stage, triggering active correction. Simultaneously, based on the magnitude of the cumulative deformation and the interpolation results of adjacent detection points, the center coordinates (X, Y) of the deformation area are calculated, and the recommended support force F and lifting stroke ΔZ are determined according to a preset support force-deformation mapping table. The support force-deformation mapping table can be calibrated using empirical formulas; for example, the recommended support force F = k... Dmax, where Dmax is the maximum cumulative deformation of the deformation area of ​​the base plate 201 in mm, and k is the proportional coefficient, which can be 4N / mm, with an upper limit of 20N. The recommended lifting stroke ΔZ = Dmax + 0.2mm (interference).

[0080] In some embodiments of the present invention, reference is made to... Figure 12 As shown, after controlling the deformation area of ​​the support base plate 201 corresponding to the correction component 2 according to the base plate deformation parameters, the server deformation correction method further includes: Step S3: Obtain the deformation rate again and compare the deformation rate with the preset rate threshold.

[0081] Specifically, while the correction component 2 maintains the deformation area of ​​the supporting base plate 201, the deformation rate is acquired again and compared with v. i (t) is related to Vaction, and the entity executing this step can be a BMC or a controller.

[0082] Step S4: If the deformation rate is less than the preset rate threshold, then maintain the support state of the correction component for the deformation area.

[0083] Where, when v i When (t) < Vaction, for example, if the deformation rate decreases from 0.03 mm / day to 0.01 mm / day, it indicates that the correction component 2 is effectively supporting the deformed area, and the support state of the correction component 2 for the deformed area can continue to be maintained. In addition, the detection component 1 can continue to collect deformation data at 10 Hz, waiting for the next trigger to achieve cyclic detection, i.e., return to step S1. Step S5: If the deformation rate is greater than or equal to the preset rate threshold, control the correction component to re-align with the deformation area of ​​the support base plate and increase the support force of the correction component on the deformation area.

[0084] Where, when v i When (t)≥Vaction, for example, if the deformation rate is still 0.03mm / day, it indicates that the support of the correction component 2 for the deformation area is insufficient, the support position of the control correction component 2 may be deviated, or the support force is insufficient. At this time, the control correction component 2 is re-aligned with the deformation area of ​​the support base plate 201 to achieve fine-tuning and calibration of the support position, and to increase the support force of the correction component 2 for the deformation area (for example, the initial support force is 5N, and the support force is increased by 1N each time it is triggered), to achieve automatic error correction and status verification, and to improve the reliability of the control correction component 2.

[0085] It should be noted that if the condition of deformation rate being greater than or equal to the preset rate threshold is triggered three times and still ineffective, a serious alarm can be reported through BMC to prompt maintenance personnel to conduct troubleshooting and repair.

[0086] In some embodiments of the present invention, reference is made to... Figure 12 As shown, before the control detection component 1 detects the deformation parameters of the base plate of the server 20, the server deformation correction method further includes: Step S0: Initialization and calibration of the server deformation correction device.

[0087] The initialization process includes: using the initial reading of the detection component 1 as a reference value, while controlling the rotating arm 231 of the correction component 2 to descend to the lowest position where it does not contact the base plate 201.

[0088] The calibration process includes: controlling the moving part 22 of the correction component 2 to move from the front end to the rear end in the X direction, and when the moving part 22 is in the middle position in the X direction, controlling the rotating arm 231 to rotate 360 ​​degrees, recording the readings of the detection component 1 and the pressure sensor 235 at each position, and constructing an initial state database.

[0089] By initializing and calibrating the server deformation correction device, we can verify whether the server deformation correction device is operating normally and ensure the adjustment accuracy of the server deformation correction device during subsequent correction.

[0090] It should be noted that the specific implementation of the server deformation correction method is similar to the implementation direction of the server deformation correction device in the above embodiments.
