Among them, the detection device 1 further includes a control circuit 11 and an actuation mechanism 12.

Please continue to refer to FIG. 1, the test host 2 of the hard disk inspection system disclosed in the present invention is provided with a hard disk slot 20. The test host 2 is controlled by the detection device 1 to execute the first hard disk confirmation procedure and the second hard disk confirmation procedure to determine whether the test host 2 detects the hard disk 3 under test, and the detection device 1 performs the first hard disk confirmation procedure and the second hard disk confirmation procedure. The judgment result of a hard disk confirming procedure and a second hard disk confirming procedure is selectively executed in a notification procedure. The test host 2 may be, for example, a programmable controller U90, but the present invention is not limited to this.

In detail, the first confirmation procedure includes the control circuit 11 of the detection device 1 controlling the test host 2 to execute a device list command to generate a device list, and determine whether there is a newly added hard disk in the device list; in other words, in the test In the device list generated by the host 2 executing the list device command, if there is a new hard drive, it means that the hard drive 3 under test is still in the hard drive slot 20 (the signal port of the hard drive under test 3 if possible 31 is still at least partially connected to the hard drive slot 20). If there is no new hard drive in the device list, it means that the hard drive 3 to be tested has been removed from the hard drive slot 20.

And the second hard disk confirmation procedure will also execute the list device command as the first hard disk confirmation procedure, so I won’t repeat it here, but if the test host 2 executes the device list command, there is a new hard disk in the device list At this time, the second hard disk confirmation procedure may further include using the test host 2 to determine whether the serial number of the newly added hard disk is consistent with the serial number of the hard disk 3 to be tested. In addition, in addition to judging whether the serial numbers are consistent, the second hard disk confirmation procedure can also include using the test host 2 to determine whether the content information of the newly added hard disk is consistent with the content information of the hard disk to be tested 3. The serial number and content information of the added hard drive are consistent with the serial number and content information of the hard drive 3 under test, which means that the hard drive connected to the hard drive slot 20 is indeed the hard drive 3 under test. The content information described herein may be the model of the hard disk 3 to be tested or other software and hardware information, such as firmware version, etc., but the present invention is not limited thereto.

Please continue to refer to FIG. 1, the control circuit 11 is electrically connected to the test host 2 to control the test host 2 to execute the first hard disk confirmation procedure and the second hard disk confirmation procedure, and the control circuit 11 outputs the unplug command and the insert command to the actuating mechanism 12 , The actuating mechanism 12 controls the connection relationship between the signal port 31 of the hard disk under test 3 and the hard disk slot 20 according to the unplugging command and the inserting command. In more detail, the control circuit 11 controls the actuating mechanism 12 to pull out the hard disk to be tested 3 from the hard disk slot 20, or controls the actuating mechanism 12 to insert the hard disk 3 to be tested into the hard disk slot 20, wherein, The control circuit 11 may be a microcontroller (Microcontroller) or other controllers with a counting function, but the present invention is not limited to this.

Please continue to refer to FIG. 1, the actuating mechanism 12 is electrically connected to the actuating circuit 11, and the actuating mechanism 12 controls the signal connection port 31 and the hard disk slot of the hard disk under test 3 according to the unplug and insert commands output by the control circuit 11 The connection between 20. For example, when the actuating mechanism 12 receives an unplugging instruction, the actuating mechanism 12 pulls the hard disk to be tested 3 out of the hard disk slot 20; when the actuating mechanism 12 receives an inserting instruction, the actuating mechanism 12 Insert the hard drive 3 to be tested into the hard drive slot 20. The actuating mechanism 12 may include a Raspberry Pi and a jig controlled/actuated by the Raspberry Pi for grabbing and moving the hard disk 3 under test.

Among them, the above-mentioned unplug and insert commands can be Python programming language commands, and the Raspberry Pi control fixture can be controlled by the Raspberry Pi to control the relays, stepping motors, and servo motors connected to the fixture. The current direction of the relay is controlled by the relay, and then the motor is controlled by the relay to drive the hard disk to be tested to perform up and down plugging actions to realize the pull-out instruction and the plug-in instruction in the hot plug detection, but the present invention is not limited to this.

Please refer to FIG. 2, which is a flowchart of a hard disk detection method according to an embodiment of the present invention. This embodiment is suitable for using the hard disk detection system as disclosed in FIG. 1 to perform hot plug detection on the hard disk 3 to be tested.

Please refer to FIGS. 1 and 2 together. The hard disk detection method disclosed in this embodiment includes step S02. The control circuit 11 of the detection device 1 controls the actuation mechanism 12 to control the signal connection port 31 of the hard disk 3 under test. The hard disk slot of the test host 2 is disconnected, and the test host 2 executes the first hard disk confirmation procedure in step S04 to determine whether the test host 2 has tested the hard disk 3 under test. Wherein, before step S02, the control circuit 11 may be used to control the actuation mechanism 12 to lock the hard disk 3 to be tested.

Following the above, when the test host 2 determines that the hard disk 3 to be tested is measured, it means that the hard disk 3 to be tested may have an abnormality in itself, and the detection device 1 executes the notification procedure in step S06. The notification procedure includes: the detection device 1 outputs an error signal to the display screen or other terminal devices, and the error signal can also be output to an error log in the cloud. In addition, the notification procedure may also be to output the error record after the detection device 1 records the error event. However, the notification procedure of the present invention is not limited to the foregoing implementation manner.

Please continue the above. If the test host 2 does not test the hard disk 3 to be tested, it means that the hard disk 3 to be tested has indeed been pulled out from the hard disk slot 30, and the control circuit 11 of the detection device 1 controls the actuation mechanism 12 to In step S08, the signal port 31 of the hard disk under test 3 is controlled to be connected to the hard disk slot 20.

When the signal port 31 of the hard disk under test 3 is connected to the hard disk slot 20, the test host 2 executes a second hard disk confirmation procedure in step S10 to determine whether the test host 2 has detected the hard disk 3 under test.

In order to explain this embodiment in more detail, please refer to steps S10 and S12 together. When the test host 2 detects the hard disk 3 to be tested, it means that the hard disk 3 to be tested has been inserted into the hard disk slot 20, and the control circuit 11 of the detection device 1 adds one to the number of inspections in step S12 to update the number of inspections . In detail, the number of detections is the number of times that the second hard disk confirmation process is executed on the hard disk under test 3 (in short, the number of detections can also be the number of times the hard disk under test 3 is inserted into the hard disk slot 20 during the hot plug detection period. The number of times).

Please continue the above steps S10 and S12, and refer to step S06' together. When the test host 2 does not detect the hard disk 3 to be tested, it means that the hard disk 3 to be tested may have an abnormality, so the detection device 1 is in step S06 'Perform notification procedures. In addition to outputting the error signal as described above, the notification procedure described here can also be to stop the hard disk detection method after the error signal is output. Add one to the number of detections to update the number of detections.

Please refer to step S14. When the detection times are updated, the control circuit 11 determines whether the updated detection times are equal to the preset times. The preset times can be different according to the detection requirements. In practice, the preset times are preferably 50 times. However, the present invention is not limited to this.

When the control circuit 11 determines that the updated detection times are not equal to (that is, less than) the preset times, the control circuit 11 of the detection device 1 again controls the hard disk under test 3 to be disconnected from the hard disk slot 20 in step S02, and Continue to perform the aforementioned subsequent steps; otherwise, when the number of detections is equal to the preset number, the control circuit 11 of the detection device 1 outputs a completion signal to the display screen or other terminal devices in step S16, but the invention is not limited to this.

Please refer to FIG. 3, which is a flowchart of another hard disk detection method depicted in the embodiment of FIG. 2 according to the present invention. The execution method of steps S02 to S14 in FIG. 3 is similar to the flowchart in FIG. 2, so it will not be repeated here. The only difference is that step S01 is executed before step S02 is executed in FIG. 3, and the other difference is step S14 in FIG. If the judgment result is no, then step S01 is executed continuously.

In more detail, step S01 in FIG. 3 is executed before step S02 in FIG. 2 is executed. The control circuit 11 of the detection device 1 controls the actuation mechanism 12 to connect the signal connection port 31 of the hard disk under test 3 to the hard disk plug Slot 20, and perform a pressure test on the hard disk 3 to be tested. The stress test includes the control circuit 11 controlling the hard disk under test 3 to continuously read and write the read and write files with a specific block size for a preset time. The value of the block size can be determined by different test requirements or It differs for different storage devices, where the value of the code group size can be 1K, 2K, 4K, or 8K, etc., but the present invention is not limited to this. The sequential reads and writes mentioned here are, for example, Sequential Reads, Sequential Writes, Random Reads, Random Writes, Mixed Sequential Reads and Writes, and Random Reads and Writes. (Mixed Random Reads and Writes), etc., and the preset time can be different according to test requirements. In practice, the preset time is preferably 10 seconds, but the present invention is not limited to this. For example, if the I/O slow insertion/removal test is performed on the hard disk under test 3, the hard disk under test can perform steps S02 to S02 after performing a stress test with a file write size (ie, block size) of 4K. Step S14 (ie, perform the insertion/removal action of the hard disk 3 to be tested), and each pressure test lasts for 10 seconds. In addition, in step S14, when the control circuit 11 determines that the number of detections is less than the preset number of times, it can also continue to return to step S01 in FIG. 3 to perform the pressure test.

Based on the above content, the hard disk detection method and hard disk detection system provided by one or more embodiments of the present invention can control the hard disk under test to perform hot plug detection on the test host through the detection device, and perform the first The hard disk confirmation procedure and the second hard disk confirmation procedure generate a device list and determine whether the hard disk to be tested is indeed removed or inserted from the slot to be tested. In addition, the second hard disk confirmation procedure can also include generation based on the test host In the device list, determine whether the hard disk in the slot to be tested is the hard disk to be tested, so as to determine in real time whether the hard disk to be tested is inserted into its corresponding slot to be tested.

Moreover, the present invention has a mechanism for recording the number of inspections. Therefore, when the number of inspections does not reach the preset number of times, the hard disk inspection system of the present invention will repeatedly perform the plug-in inspection until the number of inspections is equal to the preset number of times, as the completion of hot-plugging. Judgment criteria for testing. In addition, the notification procedure disclosed in the present invention can also allow testers to monitor the hot-plug test situation in real time.

The hard disk detection method and the hard disk detection system disclosed in the present invention can be used for common hard disk plug-in detection such as fast hot plug, slow hot plug or I/O slow plug, but the present invention does not use this Is limited. In addition, the disclosed embodiment of the present invention takes a single hard disk to be tested as an example, but the present invention can also be applied to simultaneously perform hot plug detection on a plurality of hard disks to be tested (in practice, for example, 5 hard disks to be tested) And after performing hot plug detection on the plurality of hard disks to be tested, the detection device continues to perform hot plug detection on the plurality of hard disks to be tested in the next row, so the present invention is not limited to a single hard disk to be tested.

In summary, the present invention discloses that the hard disk detection method and the hard disk detection system are operated by machines and computer devices, so human operation errors or timing errors can be avoided, and the accuracy of each test can be maintained better than that of humans. .
