When SD cards are used for aging tests on dash cams and monitoring equipment, they usually need to be mass-produced first, and then the SD card is inserted into the plug-in device to be tested for aging testing, and finally the SD card is pulled out and inserted into the computer for data verification. If there are multiple plug-in devices that need to be tested, this process needs to be repeated multiple times.

[0003] In the prior art, the specific aging test process is as follows:

[0004] 01. Insert the SD card into the card reader on the computer and run the mass production tool to mass produce the SD card first.

[0006] 03. After recording, remove the SD card from the device, insert it into the card reader on the computer, and run the verification tool to verify the data.

[0007] 04. After verification, run the formatting tool to format the SD card.

[0033] The following describes the embodiments in detail.

[0034] Please refer to Figure 1 One embodiment of the present invention provides an automatic aging and verification system for card-inserting devices. The purpose of the system is to automatically complete the aging and verification operations of the SD card. The whole process does not require manual intervention such as plugging and unplugging the card, and the whole process is completed automatically.

[0035] The system mainly includes a card insertion device 10 , an expansion board 20 , a power supply device 30 and a control device 40 .

[0036] 1. Card insertion equipment

[0037] The card device in this article refers to a device that can be plugged into an SD card, such as a driving recorder, monitoring equipment, and other card-pluggable devices. The card device can record information such as video on the SD card connected to itself for aging testing, and is also referred to as a test device in this article.

[0038] 2. Power supply device

[0039] The power supply device in this article is used to power the card device and the expansion board, and preferably uses a power timing controller. The power timing controller can provide multiple power interfaces for the card device and the expansion board respectively. The power timing controller can be connected to the control device through TCP / IP or a serial port, and the control device controls one or more power interfaces to connect the power (power on) or disconnect the power (power off). In other implementations, the power supply device can also be implemented by a relay or the like.

[0040] 3. Expansion Board

[0041] The expansion board in this article is a device used to provide an SD card expansion slot.

[0042] The expansion board may include:

[0043] Expansion slot, used to insert SD card;

[0044] Two switching switches, including a first switching switch coupled between the card insertion device and the expansion slot and a second switching switch coupled between the control device and the expansion slot;

[0045] The data transmission interface, such as a USB interface, is used to connect the control device. The second switch can be specifically coupled between the expansion slot and the data transmission interface. The data transmission interface is used to realize data transmission between the control device and the SD card inserted in the expansion slot;

[0046] A command transmission interface, such as a USB interface or a serial port, is used to connect the switch control chip and the control device so that the control device sends a control command to the switch control chip;

[0047] The switch control chip can control multiple different switching switches through multiple IOs (input and output), including controlling the first switching switch to connect or disconnect an SD card with the card insertion device, and / or controlling the second switching switch to connect or disconnect an SD card with the data transmission interface.

[0048] 4. Control device

[0049] The control device can use an independent control host, such as Figure 1 The control device runs various control software and test software, and is used to send control instructions to the switch control chip to control the first switch to connect or disconnect the SD card with one of the card devices, and / or control the second switch to connect or disconnect the SD card with the control device; and send power on / off instructions to the power supply device to control the corresponding power interface to connect or disconnect the card device and / or the expansion board.

[0050] The control device is also used to call the mass production tool to perform mass production operations on the SD card connected to itself; then control the expansion board to connect the SD card that has completed the mass production operation with the card insertion device, and the card insertion device records information to the SD card that has completed the mass production operation to perform an aging test; finally, the control device is also used to control the expansion board to connect the SD card that has completed the aging test with itself, run the verification test software, and perform a data verification operation on the SD card, that is, read the aging data in the SD card for a verification test.

[0051] Furthermore, the expansion board of the system of the present invention can be optimized, that is, the process control chip integrated on the expansion board can be used as the control device to run the control program and test program preloaded therein to realize the required functions. Optionally, the process control chip can be realized by an independent chip, and the switch control chip can also be realized by an independent chip. Alternatively, only one control chip can be set on the expansion board, and the chip can be functionally divided into two modules, switch control and process control, to realize the functions of both the process control chip and the switch control chip.

[0052] By using the process control chip integrated on the control board as the control device, the control host part can be omitted, and the instruction transmission interface can also be omitted. At the same time, due to the space saved, the device is more convenient to move and has a wider range of usage scenarios.

[0053] The working principle of the system disclosed in the present invention is described below. Taking an expansion board supporting testing of two plug-in devices as an example, a complete operation process is described, including the following steps.

[0054] S01. Insert the SD card to be tested into the expansion slot of the expansion board.

[0055] S02. Run the control program in the control device.

[0056] S03, the control device sends a control instruction to the switch control chip on the expansion board to connect the SD card connected to the expansion board to the control device.

[0057] S04, the control device calls the mass production tool to mass produce the connected SD card. The mass production referred to in this article can be understood as writing the initial boot program into the SD card hardware to complete the card opening operation.

[0058] S05. After mass production is completed, the control device sends a control instruction to the expansion board switch control chip to control the first switch (i.e., switch 1) to connect the SD card to the first card device, such as a driving recorder. At the same time, it sends a power-on instruction to the power timing controller to power on the driving recorder.

[0059] S06. The driving recorder starts recording information to the SD card for aging test.

[0060] S07, after detecting that the SD card is about to be full and the aging test is completed, the control device sends a power-off command to the power timing controller to disconnect the power supply of the driving recorder. At the same time, it sends a control command to the expansion board switch control chip to control the second switch (i.e., switch 2) to connect the SD card to the control device.

[0061] S08, when the control device detects that the SD card is successfully connected to the control device, various pre-set operations can be executed, including running the verification test program and executing the verification operation. The verification operation may specifically include: reading SD data and copying it out for storage, verifying whether the SD1 data is wrong, analyzing the SD1 data, extracting specific information from the SD card data, such as the required picture information, etc.

[0062] S09: After the control program completes the verification operation on the SD card, the SD card can be formatted for reuse. Furthermore, after formatting, the control switch 2 can be controlled to disconnect the SD card from the control device.

[0063] Furthermore, the following steps may be included:

[0064] S10, the control device sends a control instruction to the switch control chip on the expansion board to connect the SD card to the second card insertion device, such as a monitoring device;

[0065] S11, the control device sends a power-on command to the power supply device to connect the monitoring device to the power supply;

[0066] S12, the monitoring device records information into the SD card and performs an aging test;

[0067] S13, after the SD card completes the aging test, the control device sends a power-off instruction to the power supply device to disconnect the power supply of the monitoring device;

[0068] S14, the control device sends a control instruction to the switch control chip on the expansion board to connect the SD card to the control device;

[0069] S15. After the SD card is connected, the control device runs a verification program to perform a data verification operation on the SD card.

[0070] Through the above process, the driving recorder and monitoring equipment can be tested. If other card-inserted devices need to be tested, the above process can be repeated.

[0071] In summary, the present invention discloses an automatic aging and verification system and method for card insertion devices, which are used to automatically complete the aging and verification operations for SD cards, and the entire process does not require manual intervention such as plugging and unplugging the card.

[0072] The system of the present invention can connect multiple card-inserting devices, SD cards and a control device by using an expansion board, and realize the switching control between any card-inserting device and the SD card, and the switching control between the control device and the SD card, so that after the control device completes the mass production of the SD card, the SD card can be switched to be connected to a certain card-inserting device to record information to complete the aging test, and then the SD card can be switched to be connected to the control device to perform data verification operations on the SD card. Therefore, the entire aging and verification process is automatically controlled by the control device, and the entire process does not need to be intervened by manual card insertion and removal.

[0073] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0074] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. A person skilled in the art should understand that the technical solutions described in the above embodiments may still be modified, or some of the technical features may be replaced by equivalents.
