[0003] Existing manual testing requires manual plugging and unplugging of UKeys one by one. Each single test can only verify a single UKey configuration, resulting in a long test cycle and low efficiency. In addition, frequent plugging and unplugging easily causes physical wear of the UKey interface and affects the device life. Commercial USB plugging and unplugging devices are not compatible with the special UKeys of RAID cards (non-standard USB interfaces) in terms of interface form and cannot be linked with an automated test platform, making it difficult to achieve parallel control of multi-channel UKeys and simulation of short-circuit scenarios.

[0040] In order to make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0041] Currently, most of the USB plug-and-play devices available on the market are interface life testing machines, which have the following problems:

[0042] 1) The interface form does not match and cannot match the connection interfaces of RAID cards and Ukeys.

[0043] 2) It cannot be connected to an automated testing platform.

[0044] 3) It cannot achieve multi-channel controllability.

[0045] 4) It cannot simulate a short-circuit test scenario.

[0046] Based on the above analysis, as shown in Figure 1 An exemplary connection control device for plugging and unplugging multiple Ukeys of a RAID card is proposed in the present application, including: multiple Ukeys 101, a communication unit 102, a main control unit 103, and a switching unit 104; among them,

[0047] The communication unit is used for external network communication;

[0048] The main control unit is configured to receive test instructions from a test platform through the communication unit, and control the on-off unit to connect or disconnect the multiple Ukeys based on the test instructions.

[0049] The on-off unit is configured to connect or disconnect the multiple Ukeys from an external RAID card under the control of the main control unit.

[0050] Exemplarily, the multiple Ukeys are connected to one end of the on-off unit, and the other end of the on-off unit can be connected to a RAID card for testing the multiple Ukeys. The RAID card is also connected to a disk and / or a server. The on-off unit is connected to the multiple Ukeys through a one-to-multiple interface manner. Under the control of the main control unit, the on-off unit can connect the RAID card to one of the Ukeys while disconnecting the connections with other Ukeys. During the test process, the test platform sends test instructions to the communication unit based on the TCP / IP protocol, and the communication unit transmits the received test instructions to the main control unit. The main control unit can determine the Ukeys that need to be connected, disconnected, and / or opened by parsing the test instructions. Then, the main control unit sends a control signal to the on-off unit, and the control signal includes operation signals for access, removal, and / or short circuit of each Ukey; wherein, different permission configurations of the RAID card can be stored in each Ukey, and during the test process, the permission configuration in the connected Ukey takes effect.

[0051] In this way, automatic control of multiple Ukeys during the testing process of the RAID card and Ukey can be achieved, thereby replacing manual plugging and unplugging operations, achieving the purpose of saving test resources and batch testing of UKeys, thereby improving test efficiency and accuracy, and reducing interface wear and time costs caused by manual intervention.

[0052] In some optional implementation manners, the connection control device further includes: a display screen 105 and a key unit 106 connected to the main control unit;

[0053] The display screen is configured to display information transmitted by the main control unit;

[0054] The key unit is configured to transmit the received input information to the main control unit;

[0055] The main control unit is configured to reconfigure the network of the communication unit based on the network configuration parameters after receiving the network configuration parameters from the key unit.

[0056] Exemplarily, the display screen can be an OLED display screen for displaying information received from the main control unit, such as the current network configuration parameters of the connection control device, and the network configuration parameters can include but are not limited to IP address, subnet mask, and gateway address, etc.

[0057] Exemplarily, the button unit may be in the form of a matrix button. The user can input corresponding input information through the button unit, such as the network configuration parameters of the connection control device. After receiving the input information, the button unit transmits the input information to the main control unit. After receiving the input information transmitted by the button unit, the main control unit performs corresponding processing according to the previous settings. For example, when the main control unit receives the input information transmitted by the button unit as the network configuration parameters, it reconfigures the network configuration parameters to the communication unit so that after the connection control device for plugging and unplugging multiple Ukeys of the RAID card is reset, the communication unit communicates with the external network with the newly configured network configuration parameters.

[0058] Through the display screen and the button unit, the user can configure the network of the communication unit in the connection control device, so that the connection control device can be recognized in the external network.

[0059] In some alternative implementation manners, the connection control device further includes: a storage unit 107;

[0060] The main control unit is used to store the network configuration parameters in the storage unit so that after the connection control device is reset, the network configuration parameters are read from the storage unit and the network of the communication unit is configured.

[0061] Exemplarily, after the main control unit receives the network configuration parameters transmitted by the button unit, it can store the network configuration parameters in the storage unit. After the test unit is reset again, such as power-off and restart, the main control unit takes out the network configuration parameters from the storage unit and configures them to the communication unit so that the communication unit communicates with the external network with the configured network configuration parameters.

[0062] Since the network configuration parameters can be stored in the storage unit, the offline change of the network configuration and the power-off memory function can be realized.

[0063] In some alternative implementation manners, the main control unit includes a processor, and the main control unit realizes the control of the on-off unit through software running on the processor; the network configuration of the communication unit by the main control unit is realized by software developed based on the SPI protocol and running on the processor.

[0064] Exemplarily, the main control unit can be implemented by a processor, such as the STM32 chip with the ARM Cortex-M3 architecture. The functions of the main control unit can be realized by the development software running on the processor. For example, portable library functions that can run on the main control unit can be developed in advance, so as to use these library functions to realize the connection and disconnection control of multiple Ukeys. In addition, the network configuration function of the communication unit can also be realized through software. This software can be based on the SPI protocol to develop the update configuration of network configuration parameters such as IP address, subnet mask, and gateway address, and store the updated network configuration parameters in the storage unit, and re-read the network configuration parameters from the storage unit after power-off and restart to perform network configuration on the communication unit, etc.

[0065] Through the software development of the main control unit, the connection and disconnection of multiple Ukeys can be realized, reducing the development cost.

[0066] In some alternative implementation manners, the on-off unit includes an analog switch chip.

[0067] Exemplarily, as disclosed above, the on-off unit can connect or disconnect multiple Ukeys under the control of the main control unit. For this purpose, the circuit for realizing the on-off unit includes an analog switch chip, which can be a low-resistance analog switch chip with a resistance range in the ohm level. Exemplarily, the on-off unit can include chips of the TS3USB221A series, CHxxx series, and MOS transistors, etc. This way can realize the on-off control of multiple Ukeys from the hardware level.

[0068] Exemplarily, an implementation example of the connection control device for plugging and unplugging multiple Ukeys applied to the RAID card proposed in this application is as follows Figure 2As shown, a connection control device for a RAID card and a 15-channel Ukey (only 12 channels are shown in the figure) is shown in this example. Among them, the 15-channel Ukey, communication chip (i.e., communication unit), on-off chip (i.e., on-off unit), main control chip (i.e., main control unit), storage chip (i.e., storage unit), key matrix, and display screen are all integrated on this connection control device. Users can set network configuration parameters, etc. through the key matrix, and can also view the set network configuration parameters through the display screen. Among them, the communication chip can be exemplarily implemented by a w5500 / CH395L chip, which includes protocol stack, MAC, and PHY functions. The storage chip can be exemplarily implemented by a W25Qxx series chip. The RAID card is located outside this connection control device and is connected to this connection control device through the on-off unit. This connection control device can communicate with the external network through the communication chip, so as to receive test instructions sent by the test platform through the network. The RAID card is connected to the server, so as to communicate with the external network through the server, and further can communicate with the test platform. During the test, the test platform can send test instructions to the connection control device and collect the operation information of the RAID card through the external communication network, so as to complete the test.

[0069] Correspondingly, referring to Figure 3 As shown, this application also exemplarily provides a connection control method for a RAID card to plug and unplug multiple Ukeys.

[0072] Step S303: Based on the control signal, the on-off unit connects or disconnects multiple Ukeys from the external RAID card.
