Description

Technical Field

[0001] This invention relates to the field of hard disk testing technology, specifically to a smart and efficient hard disk testing device for server motherboard interfaces. Background Technology

[0002] A hard drive consists of a mechanical system responsible for storage and a circuit system responsible for control and communication. After a long period of use, hard drives age, and the effects are mainly reflected in these two aspects: first, the aging of the mechanical system, namely the aging of the read / write heads and the motor; and second, the aging of the circuit system. When the circuit system of a hard drive ages, the most common fault is that the hard drive cannot be recognized. This manifests as the hard drive suddenly failing to be recognized during operation. After restarting or leaving it idle for a period of time, it can work normally again, and the fault recurs.

[0003] When hard drives are put into mass production, aging tests should be conducted. However, existing aging tests usually use high-temperature testing in sealed devices, which cannot fully simulate the aging problems that occur during actual use. Therefore, the test results have significant deviations. Thus, how to highly simulate the aging environment of hard drives during use to improve the accuracy of test results is a problem that those skilled in the art should solve. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent and efficient hard disk testing device for server motherboard interfaces, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a smart and efficient hard disk testing device for server motherboard interfaces, comprising an exhaust assembly, a testing assembly, a pressure-bearing assembly, and a hard disk testing system, wherein:

[0006] The testing assembly includes a test chamber, with a support plate fixed to the bottom surface inside the test chamber. An electric telescopic rod is fixed in the middle of the support plate, and a turntable is connected to the top of the electric telescopic rod by a bearing. Several connecting rods are evenly fixed on the outer ring of the turntable, and clamping parts are installed at the outer ends of the connecting rods. A connection port is opened at the upper end of the clamping part, and an aging tester is installed inside the clamping part. The aging tester is connected to the connection port by a wire, and a temperature sensor is fixed on one side of the connection port. Both the aging tester and the temperature sensor are wirelessly connected to the hard disk testing system. A door is rotatably connected to one side of the test chamber.

[0007] The present invention further illustrates that the exhaust assembly includes a fan, a heating pipe, and an exhaust port, wherein:

[0008] A heating power supply is installed on the left wall of the test chamber, and the heating power supply is electrically connected to the heating tube. The fan is located above the test chamber and is connected to the internal pipe of the test chamber. A control valve is installed on the pipe. The exhaust port is located at the bottom of the test chamber.

[0009] The present invention further illustrates that the pressure-bearing assembly includes a pressure-sensing element and a pressure-bearing plate, wherein:

[0010] The upper end of the pressure measuring element is fixed to the bottom of the pressure plate, the lower end of the pressure measuring element is fixed to the top of the electric telescopic rod, and a camera is installed on the inner wall of the test box.

[0011] The hard disk testing system includes a control module, an analysis module, and a debugging module.

[0012] The present invention further describes the operation method of the hard disk testing system as follows:

[0013] S1: The test box has an open structure. Open the box door, install the hard drive under test on the clamping part in sequence, and connect the connection port. Then close the box door and the hard drive test system will start.

[0014] S2: The hard drive testing system performs aging tests on the hard drive under test. The initial heating temperature is set to 125℃ and the initial test time is T0. The exhaust component is running to simulate the internal aging environment.

[0015] S3: The test component and the exhaust component operate synchronously to control the hard drive under test to reach the preset effect state in the simulated environment, so as to achieve uniform heating and improve the accuracy of data during the aging test.

[0016] S4: After the hard drive under test reaches the preset effect, the pressure-bearing component and temperature sensor transmit the detected pressure and temperature data to the analysis module. The analysis module automatically adjusts the actual test time of the hard drive, thereby making the data received by the aging tester accurate.

[0017] The present invention further explains that the specific steps of S2 are as follows:

[0018] S21: The heating power is turned on, causing the internal heating element to reach a temperature of 125℃;

[0019] S22: The fan starts, and the external airflow enters the test chamber through the control valve and is discharged from the exhaust port, so that the warm airflow inside can be circulated to simulate the high temperature environment when the hard drive is in use.

[0020] The present invention further explains that the specific content of S3 is as follows:

[0021] As the internal airflow flows, the camera monitors the turntable's operating status. The preset detection state is that the turntable, under the influence of the internal airflow, causes the hard drive under test to rotate, with the rotational speed recorded as R, and 0. <R≤0.1r / s;

[0022] When the camera detects that the turntable is not rotating, it means that the height of the turntable is too low, causing the airflow to be dispersed and insufficient to drive the turntable to rotate. Therefore, the control module controls the electric telescopic rod to move the turntable slowly upward at a speed of v0. When the camera detects that the turntable is rotating due to the airflow, the control module controls the electric telescopic rod to stop moving upward and maintain the current height for aging test.

[0023] The test chamber is designed to have a large enough internal space. When the electric telescopic rod moves the turntable to its highest distance but before it reaches the rotation state, the control module adjusts the valve opening size of the control valve to increase the internal air intake, thereby increasing the internal airflow and causing the turntable to rotate.

[0024] The present invention further explains that the pressure-bearing component in S4 detects the airflow pressure and the pressure of dust accumulation, and records the pressure borne by the pressure plate when the turntable just starts to rotate as f, and the pressure after the device has been running stably for a fixed period of time as f. 1 The maximum pressure value that the pressure measuring element 11 can withstand is denoted as f. max .

[0025] The present invention further illustrates that the analysis module is combined with f 1 Establish a pressure change coefficient α with f, and The pressure applied to the dust is set to be less than the pressure applied to the airflow, therefore 0 ≤ α < 1.

[0026] The present invention further explains that the aging tester collects the temperature detected by the temperature sensor at the hard drive and detects the stability of the received signal. When the receiving frequency is in a stable state, the transmitted signal is 0, and when the receiving frequency is in a fluctuating state, the transmitted signal is 1.

[0027] The debugging module calculates the actual detection time T based on the temperature sensor and signal stability data.

[0028] The present invention further explains that the calculation formula for the actual detection time T is as follows:

[0029]

[0030] Where T is the initial detection time, α is the pressure change coefficient, and i is the number of times the test chamber is used for a fixed period of time to achieve uniform heating.

[0031] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: The present invention uses a test chamber, an exhaust assembly, and a test assembly to provide an open testing device for hard drive aging tests, simulating the high-temperature environment of hard drives under ventilation conditions during aging tests, which is more in line with the actual use of hard drives. At the same time, during the test, multiple hard drives are heated evenly, improving the accuracy of the test results. Attached Figure Description

[0036] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] Example 1

[0038] Please see Figure 1-2 This invention provides a technical solution: an intelligent and efficient hard drive testing device for server motherboard interfaces, comprising an exhaust assembly, a testing assembly, a pressure-bearing assembly, and a hard drive testing system, wherein:

[0039] The testing assembly includes a test chamber 1. A support plate 8 is fixed on the bottom surface inside the test chamber 1. An electric telescopic rod 9 is fixed in the middle of the support plate 8. A turntable 10 is connected to the top of the electric telescopic rod 9 by a bearing. Several connecting rods 13 are evenly fixed on the outer ring of the turntable 10. Clamping parts 14 are installed at the outer ends of the connecting rods 13. A connection port 15 is opened at the upper end of the clamping part 14. An aging tester is installed inside the clamping part 14. The aging tester is connected to the connection port 15 by a wire. A temperature sensor is fixed on one side of the connection port 15. Both the aging tester and the temperature sensor are wirelessly connected to the hard disk testing system. A door 5 is rotatably connected to one side of the test chamber 1.

[0040] The exhaust assembly includes a fan 2, a heating element 6, and an exhaust port 7, wherein:

[0041] A heating power supply 4 is installed on the left wall of the test chamber 1. The heating power supply 4 is electrically connected to the heating tube 6. The fan 2 is located above the test chamber 1. The fan 2 is connected to the internal pipe of the test chamber 1, and a control valve 3 is installed on the pipe. The exhaust port 7 is located at the bottom of the test chamber 1.

[0042] The pressure-bearing assembly includes a pressure-sensing element 11 and a pressure-bearing plate 12, wherein:

[0043] The upper end of the pressure measuring element 11 is fixed to the bottom of the pressure plate 12, and the lower end of the pressure measuring element 11 is fixed to the top of the electric telescopic rod 9. A camera is installed on the inner wall of the test box 1.

[0044] In this embodiment, an open testing device is used. The door 5 is opened, and the hard drive to be tested is connected to the interface 15. Simultaneously, the clamping part 14 secures the hard drive. During hard drive testing, the exhaust assembly circulates hot air into the interior to simulate the high-temperature environment encountered during hard drive use. A testing component and a camera are also included. The camera monitors the rotation of the hard drive on the turntable 10. When airflow is introduced from the fan 2 and discharged from the exhaust port 7, the turntable 10 rotates around the top of the electric telescopic rod 9. Through this rotation process, the hard drive undergoes an aging test. To achieve uniform heating during testing, when the camera detects that the turntable 10 is not rotating, the turntable 10 can be moved upward by raising the electric telescopic rod 9 to increase the pressure of the airflow on the turntable 10, causing it to rotate. If the turntable 10 still does not rotate, the control valve 3 can be adjusted to increase the airflow, thereby causing the turntable 10 to rotate. This simulates the high-temperature environment of the hard drive under ventilation conditions during aging testing, which is more in line with the actual usage of the hard drive. At the same time, it achieves uniform heating of multiple hard drives during the test, improving the accuracy of the test results.

[0045] When the hard drive needs to be replaced, simply open door 5 to replace the hard drive; the operation is simple.

[0046] Example 2

[0047] Please see Figure 1-2 The structure of this embodiment is basically the same as that of Embodiment 1, except that the following structure is added on the basis of Embodiment 1: The hard disk testing system includes a control module, an analysis module and a debugging module;

[0048] The control module controls the operation of the exhaust assembly, testing assembly, and pressure-bearing assembly. The exhaust assembly controls the flow of hot air inside the testing device to provide a high-temperature environment for aging tests. The testing assembly, in conjunction with a camera, adjusts the testing status of the internal hard drive to ensure that the hard drive under test, connected to connector 15, rotates slowly to achieve a preset effect of uniform heating. The pressure-bearing assembly detects internal pressure and transmits the detected data to the analysis module. The analysis module analyzes the uniformity of heating and the stability of the internal detection data based on the data from the pressure-bearing assembly and the aging tester. The adjustment module adjusts the internal heating time based on real-time data from the temperature sensor.

[0049] The hard drive testing system operates as follows:

[0050] S1: Test box 1 has an open structure. Open the door 5, install the hard drive to be tested on the clamping part 14 in sequence, and connect the connection port 15. Then close the door 5 and the hard drive test system starts.

[0051] S2: The hard drive testing system performs aging tests on the hard drive under test. The initial heating temperature is set to 125℃ and the initial test time is T0. The exhaust component is running to simulate the internal aging environment.

[0052] S3: The test component and the exhaust component operate synchronously to control the hard drive under test to reach the preset effect state in the simulated environment, so as to achieve uniform heating and improve the accuracy of data during the aging test.

[0053] S4: After the hard drive under test reaches the preset effect, the pressure-bearing component and temperature sensor transmit the detected pressure and temperature data to the analysis module. The analysis module automatically adjusts the actual test time of the hard drive, thereby making the data received by the aging tester accurate.

[0054] The specific steps of S2 are as follows:

[0055] S21: The heating power supply 4 is activated, causing the internal heating element 6 to reach a temperature of 125°C;

[0056] S22: Fan 2 starts, external airflow enters the test chamber 1 through control valve 3 and is discharged from exhaust port 7, so that warm airflow flows inside to simulate the high temperature environment when the hard drive is in use.

[0057] The specific content of S3 is as follows:

[0058] When the internal air flow is flowing, the camera monitors the operating state of the turntable 10. The detection state of the preset effect is set as that under the action of the internal air flow, the turntable 10 drives the hard disk to be tested to rotate, and the rotation speed is recorded as R, and 0 < R ≤ 0.1 r / s. The rotation operation through the air flow not only saves the use of motor energy, but also better imitates the hot air influence effect of the hard disk in actual use. The above process makes the hard disk to be tested evenly heated in a high-temperature environment, making the test results accurate;

[0059] When the camera detects that the turntable 10 does not rotate, it means that the height of the turntable 10 is too low, resulting in the dispersion of the air flow, which is not enough to drive the turntable 10 to rotate. Therefore, the control module controls the electric telescopic rod 9 to slowly move the turntable 10 upward at a moving speed of v0. When the camera detects that the turntable 10 rotates under the action of the air flow, the control module controls the electric telescopic rod 9 to stop moving upward and maintain the existing height for aging test;

[0060] It is set that the internal space of the test chamber 1 is large enough. When the electric telescopic rod 9 drives the turntable 10 to move upward to the maximum distance and does not reach the rotating state, the control module increases the internal air intake by adjusting the valve opening size of the control valve 3, so that the internal air flow increases to promote the turntable 10 to rotate.

[0061] The pressure-bearing component in S4 detects the air flow pressure and the pressure of dust accumulation, and records the pressure on the bearing plate 12 when the turntable 10 just starts to rotate as f, and the pressure after a fixed period of stable operation of the device as f 1 。

[0062] Among them, f is set to that when just reaching the preset effect, only the air flow applies a downward pressure to the bearing plate 12, and the pressure-measuring element 11 detects the pressure applied by the air flow. After running for a fixed period, the air flow introduces dust into the test chamber 1 to simulate the dust accumulation state of the hard disk after long-term operation, f 1 is the combined pressure of the dust accumulation on the bearing plate 12 and the air flow, and it is set that the maximum pressure value of the air pressure borne by the pressure-measuring element 11 is recorded as f max 。

[0063] The analysis module combines f 1 and f to establish a pressure change coefficient α, and where it is set that the pressure applied by the dust is less than the pressure applied by the air flow, so 0 ≤ α < 1.

[0064] The aging tester collects the temperature detected by the temperature sensor at the hard disk and detects the stability of the received signal. When the received frequency is in a stable state, the transmitted signal is 0, and when the received frequency is in a fluctuating state, the transmitted signal is 1;

[0065] The debugging module calculates the actual detection time T based on the temperature sensor and signal stability data;

[0066] The debugging module is run as follows:

[0067] A1: The temperature sensor transmits the detected temperature data to the analysis module to check whether the hard drive under test has been heated evenly. If the hard drive under test is found to have not been heated evenly, the pressure-bearing component will not be tested first, and will be rotated and heated for a second fixed time period until the heating is even.

[0068] When the test results of the hard drive under test reach the level of uniform heating, first determine whether the received signal of the aging tester is stable, and then proceed to the next processing step based on the signal stability.

[0069] A2: Under the conditions set in A1, when the received signal is 0, it indicates that the heating is uniform and the signal is stable. The debugging module adjusts the actual detection time according to the pressure change coefficient α and marks the actual detection time as T. Considering the influence of dust factors, the accuracy of hard drive aging detection is improved.

[0070] When the received signal is 1, it indicates that the heating is uniform but the signal is unstable. The debugging module will directly issue an alarm, prompting the staff to shut down the test system and replace the hard drive with the unstable signal.

[0071] The formula for calculating the actual detection time T is as follows:

[0072]

[0073] Where T is the initial detection time, α is the pressure change coefficient, and i is the number of times the test chamber 1 is used for a fixed period of time to achieve uniform heating.

[0074] In this embodiment, dust data is incorporated during the airflow introduction process. Dust is also a factor affecting the lifespan of the hard drive. During the aging test, the detection time is automatically adjusted according to the amount of dust. The detection time is inversely proportional to the amount of dust. When there is more dust, the detection time should be shortened under high temperature conditions in order to accurately obtain the aging data related to the hard drive.
