Example 1
The description is made in conjunction with a schematic structural diagram of the storage device detection apparatus shown in fig. 1.
Exemplarily, the present embodiment provides a storage device detection apparatus, including a driver, a microcontroller, a detection connection interface, and a differential signal interface, where the driver is connected to the upper computer through the differential signal interface A, B to receive a test signal from the upper computer, and analyze the test signal into a level signal that can be recognized by the microcontroller, and transmit the level signal to the microcontroller, and the microcontroller further analyzes the level signal to implement access and specific test on a storage device to be tested through the detection connection interface. In the detection process, the microcontroller can execute various test cases specified by the upper computer.
The upper computer can be a terminal device such as a computer and the like, and is connected with the detection device through a differential signal line. The test case is mainly issued by the test signal in the form of a signaling message to the storage device detection apparatus, and may be sent by using, for example, a Modbus protocol or other user-defined protocols.
In one embodiment, the upper computer issues a test case to the microcontroller to execute through the RS-485 differential bus. The driver, which supports the TIA/EIA-485 standard, may be an RS-485 driver, for example, as shown in fig. 2, where R is an input receiver, D is an output transmitter for transmitting and receiving signals, and the MCU connected thereto is a microcontroller.
Further optionally, the microcontroller is further connected with an indication module formed by LED lamps with different colors (such as red and green, etc.), wherein the LED lamps are used for indicating whether the test is successful, and when the test is successful, the green lamp is turned on, and when the test is failed, the red lamp is turned on, so that the test result is simply represented. In addition, the microcontroller is also connected with an input module consisting of a key K1, the key K1 can be used for controlling the start and the end of the test case of the storage device, the execution of the test can be conveniently controlled through a peripheral key, the code instruction input on the upper computer is reduced, the operation time is effectively reduced, the test efficiency is improved, and the like.
In this embodiment, the upper computer sends a test signal containing a test case through a communication link such as RS-485, and the test signal is analyzed by the driver and the microcontroller to obtain the test case, and then the test case is used to test the connected storage device. Taking a test procedure as an example, when the test is started, the key K1 can be turned on, and the storage device starts to test the connected storage device with the accepted test case. After the test is finished, the key K1 is turned off, the storage device is pulled out, and after the test is finished, whether the test is successful or not is indicated through the bright condition of the LED lamp.
It is understood that besides the LED lamp and the single key as described above, whether the test is successful or not can be indicated by a display screen or a buzzer, and the number of keys can be multiple, so as to achieve more complicated adjustment, even a knob, a keyboard and other control input components, which is not limited herein.
The storage device for the test supported by the storage device detection apparatus of the present application includes, but is not limited to, different storage devices such as a mechanical hard disk, a solid state disk, an eMMC, a TF card, and an SD card, as shown in fig. 2, the plug-in interface in the present embodiment is adapted to the SATA hard disk, and therefore, the plug-in interface can be used to test the SATA hard disk. It is understood that, depending on the test interface, different storage devices may be tested, such as fig. 3, where the plug-in interface is a plug-in interface of USB, and thus the device in fig. 3 may be used for testing a USB device.
Referring to fig. 4, in another embodiment, the storage device detection apparatus may further include a converter disposed between the microcontroller and the detection connection interface, for implementing data signal conversion or transparent transmission between the microcontroller and the detection connection interface. The data signal conversion function is mainly used for working scenes with different protocols supported by the interface access storage device and the microcontroller, and the converter is used for 'translation', so that two devices which use different electrical protocols and cannot originally perform signal communication can perform barrier-free access and test work. And for the transparent transmission function, the transparent transmission function is mainly used for the situation that the protocol used by the accessed storage device is the same as that of the microcontroller, and the signal can be directly transmitted through without the translation action of a converter, so that the microcontroller can access the connected storage device to be tested.
The converter will vary due to the different storage devices supported by the test connection interface and the different protocols supported by the microcontroller. Illustratively, as shown in table 1 below, the converter may include, but is not limited to, supporting signal conversion between electrical protocols between any two of a USB interface, a SATA interface, a mSATA interface, a SATA DOM interface, and an m.2 interface.
TABLE 1
| Source interface | Destination interface |
| USB(USB2.x,USB3.x,etc) | SATA |
| USB(USB2.x,USB3.x,etc) | mSATA |
| USB(USB2.x,USB3.x,etc) | M.2 |
| USB(USB2.x,USB3.x,etc) | M.2(NVMe) |
| SATA(SATA I,SATA II,SATA III,etc) | SATA |
| SATA(SATA I,SATA II,SATA III,etc) | mSATA |
| SATA(SATA I,SATA II,SATA III,etc) | M.2 |
| SATA(SATA I,SATA II,SATA III,etc) | M.2(NVMe) |
It is understood that when testing a certain storage device, the converter may be a converter only supporting signals between two interfaces, for example, as shown in fig. 5, a usb3.x to SATA converter is provided in the microcontroller and the detection connection interface, and the converter is used for implementing data conversion between the microcontroller MCU and the SATA hard disk. In addition, the converter can be a converter for signal conversion among a SATA interface, a mSATA interface, a SATA DOM interface, and an m.2 interface, depending on the converter to be mounted.
Further, the memory space in the microcontroller is divided into three areas, namely a BootLoader boot area, a free Idle FW firmware area and a test case Task FW firmware area. The BootLoader boot area is used for firmware to execute common system boot and can be used for manually updating Idle firmware FW; and the firmware in the Idle FW firmware area executes a Task of dynamically updating the firmware in the Task FW area, and if the upper computer does not issue an updating signaling, the operation of updating the firmware is skipped, and the test case in the Task FW firmware area is directly executed.
For example, when the memory device detection apparatus of the embodiment of the present application is used for detection.
Firstly, a power supply is electrified, and a microcontroller executes firmware of a BootLoader area; then, jumping (Jmp Idle) and loading the firmware of the Idle FW firmware area, and executing the Idle FW firmware; then, jumping (Jmp Task) and loading the firmware of the Task FW firmware, and executing the Task FW firmware; finally, jump (Reset Idle) and load the firmware of Idle FW firmware, and execute Idle FW firmware.

In this embodiment, the upper computer may be connected to the plurality of storage device detection apparatuses in parallel. The storage device detection apparatus in embodiment 1 may be used as each storage device detection apparatus. Further, a resistor is connected in series at the end of the differential signal line, and the resistor is a termination resistor, so that the signal does not reflect after reaching the end of the transmission line, so as to reduce the influence caused by the reflected signal.
When a plurality of storage equipment detection devices are connected, each detection device is provided with a unique access address, so that the upper computer can identify different storage equipment detection devices. For example, when a certain address is accessed or tested, only the corresponding signal needs to be issued according to the corresponding unique address.
In this embodiment, the number of the storage device detection apparatuses connected to the upper computer may be one or more, and the detected storage devices may be the same or different, for example, as shown in fig. 3 and 5, schematic diagrams are respectively shown in which the upper computer is connected to a single storage device detection apparatus, and tests are performed on the SATA device and the USB device. As shown in fig. 6, three detection devices are connected in parallel to the upper computer, a first device is used for detecting the solid state disk, a second device is used for detecting the mechanical hard disk, a third device is used for detecting the TF card, and the like.
In the embodiment of the application, the RS-485 links are connected in parallel, so that the system scale can be rapidly expanded or contracted, and the problem of fluctuation of the number of the tested products in different batches can be conveniently and dynamically responded.
