Description

Technical Field

[0001] This invention belongs to the field of power supply detection, specifically a power supply current sharing detection device and method for computing servers. Background Technology

[0002] A computing server is a server specifically designed to provide powerful computing capabilities. In a computing server, due to the need to handle a large number of computing tasks, the power system is usually composed of multiple power modules connected in parallel to provide sufficient power and redundancy. The role of the power current sharing detection device is to ensure that these power modules can evenly distribute the load when working in parallel, and to avoid some modules being overloaded and damaged.

[0003] Existing power current sharing detection devices mainly utilize the Hall effect when collecting current from power modules. The output wires of the power module are passed through the through-hole of the Hall current sensor. The current in the wires generates a magnetic field around the sensor. The Hall element detects the change in the magnetic field and outputs a voltage signal proportional to the current.

[0004] However, this method of power supply detection usually has some drawbacks. In actual detection, the position of the power supply wire is arbitrary. It may be bent and attached to the inside of the sensor or located in other non-central positions on the inside. This will lead to uneven magnetic field distribution, increase measurement error and reduce measurement accuracy. On the other hand, it makes the sensor more susceptible to interference from external magnetic fields, affecting the accuracy and stability of the Hall current sensor current acquisition, and thus reducing the accuracy and reliability of current sharing detection.

[0005] To address the problems raised in the background art, those skilled in the art have proposed a power sharing detection device and method for computing servers. Summary of the Invention

One end of the bidirectional screw passes through the corresponding upright plate and is connected to a handle. Two sets of moving blocks are connected to the bidirectional screw with opposing threads. A connecting plate is provided on the top of the moving plate. A connecting rod is rotatably connected between the two sets of moving blocks and the connecting plate.

[0011] Preferably, the drive mechanism includes a cross shaft, a manual control component, and gears.

A cross shaft passing through the Hall current sensor is rotatably arranged between the two horizontal sections of the C-shaped frame. A manual control component for driving the rotation of the Hall current sensor is arranged in the middle of the cross shaft. Two sets of gears are symmetrically slidably connected on the cross shaft. Ear plates are connected to the lower side of the two sets of moving disks. The two sets of gears rotate on the opposite sides of the two sets of ear plates. The two sets of gears mesh with the two sets of gear disks respectively.

[0012] Preferably, both sets of ear plates and Hall current sensors are provided with circular holes for the cross shaft to pass through, and the bottom of the side of the Hall current sensor is provided with a groove communicating with the corresponding circular hole, and the manual control component is located inside the groove.

[0016] This invention also proposes a power supply current sharing detection method for computing servers, which uses the aforementioned power supply current sharing detection device for computing servers and includes the following steps: Step 1: Preparation: Connect the Hall current sensor to the power tester with wires, and pass the power wires of the computing server to be tested through the through holes in the middle of the corresponding Hall current sensor. Step 2, center and fix the power cord: Manually guide the cord to the center of the through hole, and then use the drive mechanism to drive the gear plate to rotate, so that the gear plate pushes the moving rod on the inner side of the moving plate through the limit shaft to move the fixing block, thereby centering and fixing the power cord in a circle. Step 3: Straighten the power cord: By operating the straightening mechanism, the two moving discs move the fixed power cord in opposite directions, thereby straightening the power cord located in the through hole; Step 4: Perform current sharing test: Turn on the power supply of the computing server and the power supply tester. The power supply tester collects the current signal of the power supply wires in real time through the Hall current sensor of the acquisition module. The collected current signal is transmitted to the signal conditioning module inside the power supply tester. The signal conditioning module filters and amplifies the signal, and then transmits the processed signal to the microprocessor module. The microprocessor module analyzes and processes the received signal, calculates the current value of each power supply wire, and determines whether the current between the power supply wires is balanced. The test results are displayed through the front control and display module, allowing operators to intuitively view the test results.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting up a centering component and a straightening mechanism, the power supply wires can be first fixed in the center from both sides of the Hall current sensor, and then the fixed power supply wires can be straightened, so that the power supply wires in the through hole are in a relatively taut state. This effectively avoids the problem of uneven magnetic field distribution caused by improper wire position, reduces measurement error, and improves measurement accuracy. At the same time, the straightened wires also reduce the possibility of the sensor being interfered with by external magnetic fields, further improving the accuracy and stability of current acquisition, thereby improving the accuracy and reliability of current sharing detection.

[0018] 2. By setting up a driving mechanism, the present invention can manually drive two sets of centering components to perform synchronous centering operations, which makes it convenient for users to quickly center and fix the power cord. The straightening mechanism, through the cooperation of a bidirectional screw, a moving block and a connecting rod, can easily drive the two sets of centering components to straighten the fixed power cord, making the overall operation very convenient.

[0021] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0022] Example 1 As attached Figure 1 To be continued Figure 8 As shown: This invention provides a power supply current sharing detection device for a computing server, including a power supply detector 1, a guide 2, an alignment component 3, a straightening mechanism 4, and a driving mechanism 5. The power supply detector 1 has a data acquisition module on its side, which includes a Hall current sensor 6 connected to the acquisition port of the power supply detector 1 via multiple sets of wires. The Hall current sensor 6 has a through hole 61 in its center for the power supply wire to be tested to pass through. Alignment components 3 are movably mounted on both sides of the Hall current sensor 6 via the guide 2, and are used to center and fix the power supply wire from both sides of the Hall current sensor 6. A straightening mechanism 4 is located on the top of the Hall current sensor 6, which drives the two sets of alignment components 3 to straighten the fixed power supply wire, so that the power supply wire inside the through hole 61 is in a relatively taut state. A driving mechanism 5 is located on one side of the Hall current sensor 6 for manually driving the two sets of alignment components 3 to perform synchronous centering operations.

[0023] refer to Figure 2 , Figure 3 and Figure 7 The centering component 3 includes a movable disk 31, a movable rod 32, a fixed block 33, a limiting shaft 34, and a gear disk 35. The gear disk 35 is rotatably disposed on one side of the movable disk 31. Both the movable disk 31 and the gear disk 35 have a clearance hole coaxially arranged with the through hole 61 in the middle. The movable disk 31 has multiple sets of rectangular grooves 311 equidistantly arranged on the inner wall of the clearance hole. The movable rod 32 slides through each set of rectangular grooves 311. One end of the movable rod 32 is connected to the fixed block 33. The side of the movable rod 32 away from the fixed block 33 is connected to the limiting shaft 34 that passes through the movable disk 31 and the gear disk 35. The gear disk 35 has multiple sets of variable diameter arc-shaped through grooves 351 equidistantly arranged on the circumference for the limiting shaft 34 to pass through. The movable disk 31 has multiple sets of guide slots 312 corresponding to the rectangular grooves 311.

[0024] The centering component 3 rotates via the gear disk 35, and the variable diameter arc-shaped through groove 351 on it pushes the limiting shaft 34 to move. The limiting shaft 34 drives the moving rod 32 to slide in the rectangular groove 311 of the moving disk 31. The fixing block 33 at the end of the moving rod 32 moves accordingly, and the power wire passing through the through hole 61 of the Hall current sensor 6 is centered and fixed from multiple directions to ensure that the power wire is located at the center position on both sides of the through hole 61 of the Hall current sensor 6.

[0025] refer to Figure 5 The guide component 2 includes a guide rod 21, an anti-detachment plate 22, and a sliding sleeve 23. The center of both sides of the Hall current sensor 6 is provided with a guide rod 21, and the two ends of the two sets of guide rods 21 are connected to the anti-detachment plate 22. The sliding sleeve 23 sleeved on the anti-detachment plate 22 is connected to both sides of the moving disk 31.

[0026] The sliding sleeve 23 is fitted onto the anti-detachment plate 22 and connected to the moving plate 31. When the straightening mechanism 4 drives the moving plate 31 to move, the sliding sleeve 23 slides along the guide rod 21 to guide the movement of the moving plate 31, ensuring that the moving plate 31 maintains linear motion during the movement, avoiding deviation, and ensuring the accuracy of centering, fixing and straightening operations.

[0027] refer to Figure 5 The straightening mechanism 4 includes a bidirectional screw 41, a moving block 42, and a connecting rod 43. The Hall current sensor 6 has two symmetrically arranged vertical plates at its top ends. A bidirectional screw 41 is rotatably arranged between the two sets of vertical plates. One end of the bidirectional screw 41 passes through the corresponding vertical plate and is connected to a handle 44. Two sets of moving blocks 42 are connected to the bidirectional screw 41 with opposing threads. A connecting plate 7 is arranged on the top of the moving disk 31. A connecting rod 43 is rotatably connected between the two sets of moving blocks 42 and the connecting plate 7.

[0028] The bidirectional screw 41 is driven to rotate by rotating the handle 44 at one end of the bidirectional screw 41, which in turn drives the two sets of moving blocks 42 to move closer or further apart. The moving blocks 42 are rotatably connected to the connecting plate 7 at the top of the moving disk 31 through the connecting rod 43. When the moving blocks 42 move, the moving disk 31 moves along the guide rod 21 through the connecting rod 43, thereby straightening the power wires fixed at both ends, so that the power wires are suspended in the center of the through hole 61.

[0029] refer to Figure 4 The drive mechanism 5 includes a cross shaft 51, a manual control component 52, and gears 53. A horizontally placed U-shaped frame 8 is connected to the bottom of one side of the Hall current sensor 6 via an angle bracket. A cross shaft 51 passing through the Hall current sensor 6 is rotatably arranged between the two horizontal sections of the U-shaped frame 8. A manual control component 52 for driving its rotation is arranged in the middle of the cross shaft 51. Two sets of gears 53 are symmetrically slidably connected on the cross shaft 51. Ear plates 9 are connected to the lower side of the two sets of moving disks 31. The two sets of gears 53 rotate on the opposite sides of the two sets of ear plates 9. The two sets of gears 53 are respectively meshed with the two sets of gear disks 35.

[0030] The cross shaft 51 is driven to rotate by the manual control component 52. During the rotation of the cross shaft 51, the gear 53 is driven to rotate. The gear 53 meshes with the gear plate 35 to realize the centering operation of the centering component 3. This enables the manual driving of two sets of centering components 3 to perform synchronous centering operations, which makes it convenient for users to quickly center and fix the power cord, improving the convenience and efficiency of operation.

[0031] refer to Figure 4 and Figure 5 Both sets of ear plates 9 and Hall current sensor 6 are provided with circular holes for the cross shaft 51 to pass through. The bottom of the side of the Hall current sensor 6 is provided with a groove 62 that communicates with the corresponding circular hole. The manual control component 52 is located inside the groove 62.

[0032] refer to Figure 5 and Figure 8 The manual control component 52 includes a worm gear 521, a worm 522, and a handwheel 523. The worm gear 521 is connected to the middle of the cross shaft 51. The worm 522 is rotatably arranged in the groove 62. The worm 522 is meshed with the worm gear 521. One end of the worm 522 passes through the U-shaped frame 8 and is connected to the handwheel 523.

[0033] The handwheel 523 drives the worm gear 522 to rotate, which in turn drives the worm wheel 521 to rotate. The worm wheel 521 then drives the cross shaft 51 to rotate. The worm wheel 521 and worm gear 522 transmission has a self-locking function. When the handwheel 523 stops rotating, the cross shaft 51 can maintain a fixed position, ensuring the stability of the centering component 3 and preventing changes in the centering state due to external factors.

[0034] refer to Figure 2 The Hall current sensor 6 has suction cups 10 for fixing at each of its four corners.

[0035] The Hall current sensor 6 is fixed by pressing the suction cup 10 to attach it to the mounting surface.

[0036] The power supply detector 1 is internally equipped with a signal conditioning module, a microprocessor module, a communication module and a power supply module, and a control and display module is located on the front side of the power supply detector 1.

[0037] The signal conditioning module filters and amplifies the current signal collected by the Hall current sensor 6 to improve signal quality and provide accurate data for subsequent analysis and processing by the microprocessor module. The microprocessor module analyzes and processes the processed signal to calculate the current value of each power supply wire and determine whether the current between the power supply wires is balanced, thereby realizing automated current sharing detection. The communication module can transmit the detection results to a computer or other storage device for convenient subsequent analysis and archiving, realizing remote data transmission and sharing. The control and display module facilitates user operation and viewing of detection results.

[0038] Example 2 The present invention proposes a power supply current sharing detection method for computing servers, comprising the following steps: Step 1, Preparation: Connect the Hall current sensor 6 to the power tester 1 through the wires, and pass the power wires of the computing server to be tested through the through holes 61 in the middle of the corresponding Hall current sensor 6 one by one. Step 2, centering and fixing the power cord: manually guide the cord to the center of the through hole 61, and then use the drive mechanism 5 to drive the gear plate 35 to rotate, so that the gear plate 35 pushes the moving rod 32 inside the moving plate 31 through the limit shaft 34 to drive the fixing block 33 to move, thereby centering and fixing the power cord in a circle. Step 3: Straighten the power cord: By operating the straightening mechanism 4, the two moving disks 31 are driven to move the fixed power cord in opposite directions, thereby straightening the power cord located in the through hole 61. Step 4: Perform current sharing test: Turn on the power supply of the computing server and the power supply tester 1. The power supply tester 1 collects the current signal of the power supply wires in real time through the Hall current sensor 6 of the acquisition module. The collected current signal is transmitted to the signal conditioning module inside the power supply tester 1. The signal conditioning module performs filtering, amplification and other processing on the signal, and then transmits the processed signal to the microprocessor module. The microprocessor module analyzes and processes the received signal, calculates the current value of each power supply wire, and determines whether the current between the power supply wires is balanced. The test results are displayed through the front control and display module, allowing the operator to view the test results intuitively. At the same time, the test results can be transmitted to a computer or other storage device through the communication module for subsequent analysis and archiving.

[0039] Working Principle: In summary, when using this invention, firstly, the Hall current sensor 6 is connected to the power detector 1 via wires. The power wires of the computing server to be tested are then passed through the corresponding through-holes 61 in the center of the Hall current sensor 6. After manually guiding the wires to the center of the through-holes 61, the handwheel 523 of the manual control component 52 in the drive mechanism 5 drives the worm gear 522 to rotate. The worm gear 522 drives the worm wheel 521 and the cross shaft 51 to rotate. The gear 53 on the cross shaft 51 rotates accordingly, driving the gear disk 35 to rotate. The variable-diameter arc-shaped through groove 351 on the gear disk 35 pushes the limiting shaft 34 to move. The limiting shaft 34 drives the moving rod 32 to slide within the rectangular groove 311 of the moving disk 31, causing the fixing block 33 at the end of the moving rod 32 to circumferentially center and fix the power wires from multiple directions. Then, the straightening mechanism 4 is operated, rotating the double... The handle 44 at one end of the screw 41 rotates, causing the two sets of moving blocks 42 to move away from each other. The moving blocks 42 drive the moving disk 31 to move along the guide rod 21 through the connecting rod 43, thereby straightening the power wires fixed at both ends, so that the power wires are suspended in the center of the through hole 61. Then, the computing server power supply and power detector 1 are turned on. The power detector 1 collects the current signal of the power wire in real time through the Hall current sensor 6 of the acquisition module. The signal is transmitted to the signal conditioning module inside the power detector 1 for filtering, amplification and other processing. The processed signal is transmitted to the microprocessor module for analysis and processing, calculates the current value of each power wire and judges whether the current is balanced. The detection result is displayed through the control and display module, and can also be transmitted to a computer or other storage device through the communication module for subsequent analysis and archiving.
