Description

Technical Field

[0001] This invention relates to the field of data transmission technology, and in particular to a shared serial port identification method, apparatus, computer device, and storage medium. Background Technology

[0002] With the development of the domestic storage industry, the "one-frame, four-controller" storage control chassis has gradually become a trend in high-end storage due to its strong reliability of three out of four failures. "One-frame, four-controller" refers to a chassis containing four controllers (i.e., motherboards).

[0003] In existing technologies, each controller contains at least an x86 main operating system and a BMC management subsystem. Some designs also include an additional FPGA system or a dedicated ASIC system. All of these systems need to provide external debugging serial ports for R&D and maintenance personnel.

[0004] As the number of controllers adapted within the frame reaches four, with the controllers providing the X86 business main operating system and the BMC management subsystem, the total number of serial ports will reach eight.

[0005] The storage control unit is highly integrated, and due to space limitations, only one serial port can usually be reserved on the front panel of the chassis. Therefore, it is necessary for four controllers to share a single serial port.

[0006] A single-pole eight-way switch is implemented by connecting all serial ports to the CPLD on the management module. The user inputs a character to the CPLD through the "headphone jack" input channel, and the CPLD controls the toggle of the single-pole eight-way switch by recognizing different characters.

[0007] The constant switching between the eight serial ports can lead to confusion. For example, the serial port output characters of the main operating system on controller 1 and controller 2 might be identical. When a user switches from controller 1 to controller 2, they cannot determine whether the switch was successful. Similarly, the user cannot know which controller the current serial port is connected to. Users can only determine this indirectly through other methods (such as checking the controller serial number or IP address), causing significant inconvenience for development and maintenance.

[0008] In existing technologies, the serial port data received by the serial port access device is encoded by combining it with the identification information allocated from the data channel for identification, and a highlighted, color-coded display method is used. This solves the problem of distinguishing serial port data from multiple data channels when there is a one-to-one correspondence between devices and serial ports. However, it does not solve the problem of identifying the currently connected device when multiple devices share a serial port. Summary of the Invention

[0009] The purpose of this invention is to provide a shared serial port identification method, device, computer equipment, and storage medium.

[0010] The technical solution of this invention is:

[0011] Firstly, a shared serial port identification method is provided, the method comprising:

[0012] Based on the preset channel switching identifier character detection logic, the running data is detected in real time to determine whether there is a channel switching identifier character input;

[0013] If so, the target channel number is obtained based on the input channel switching identifier character;

[0014] Send the target channel number to the maintenance terminal and obtain the target font color setting command returned by the maintenance terminal based on the target channel number;

[0015] Based on the target font color setting command, modify the font color and font background color of the corresponding identifier of the target channel to distinguish each serial port channel.

[0016] Furthermore, the step of detecting running data in real time based on the preset channel switching identifier character detection logic to determine whether there is a channel switching identifier character input includes:

[0017] The system detects running data based on the RX input from the headphone jack and the preset channel switching identifier character to determine whether there is a channel switching identifier character input.

[0018] Furthermore, after determining whether there is a channel switching identifier input based on the RX input from the headphone jack and the preset channel switching identifier character detection running data, the method further includes:

[0019] The single-pole multi-throw switch is controlled by recognizing the preset channel switching identifier character.

[0020] Furthermore, after the method detects running data in real time based on the preset channel switching identifier character detection logic to determine whether there is a channel switching identifier character input, if so, the method further includes:

[0021] The single-pole multi-throw switch is set to a floating state.

[0022] Furthermore, after modifying the font color and background color of the corresponding identifier of the target channel based on the target font color setting command to distinguish each serial port channel, the method further includes:

[0023] Determine whether the font color and background color of the corresponding label for each channel have been modified;

[0024] Disable UART-transmit logic;

[0025] Switch the single-pole multi-throw switch according to the target channel number.

[0026] Furthermore, the target font color setting command includes at least font color setting logic, which includes:

[0027] Set the color control combination as: ESC character + character "[" + character "color code" + character "m";

[0028] Set the ASSIC character to hexadecimal or binary.

[0029] Furthermore, after determining whether a channel switching identifier character has been input by real-time detection of running data based on a preset channel switching identifier character, the method further includes:

[0030] If not, then continue with the real-time detection.

[0031] Secondly, a shared serial port identification device is provided, the device comprising:

[0032] The detection and judgment module is used to detect the running data in real time based on the preset channel switching identifier character detection logic to determine whether there is a channel switching identifier character input;

[0033] The acquisition module is used to acquire the target channel number based on the input channel switching identifier character when the judgment result of the detection and judgment module is yes;

[0034] The send-return module is used to send the target channel number to the maintenance terminal and obtain the target font color setting command returned by the maintenance terminal based on the target channel number;

[0035] The modification module is used to modify the font color and font background color of the corresponding identifier of the target channel based on the target font color setting command in order to distinguish each serial port channel.

[0036] Thirdly, a computer device is provided, the computer device including one or more processors; and a memory associated with the one or more processors, the memory for storing program instructions, which, when read and executed by the one or more processors, perform the steps of the shared serial port identification method as described in any one of the first aspects above.

[0037] Fourthly, a computer-readable storage medium is provided having a computer program stored thereon, which, when executed by a processor, performs the steps of the shared serial port identification method as described in any one of the first aspects above.

[0038] The technical solution described in this application has the following advantages over the prior art:

[0039] In this application, data is detected in real time through channel switching identifier character detection logic. If the channel switching identifier character is present, the target channel number is sent to the maintenance terminal, which sets the target font color setting command to lock the font color setting logic. Different serial port character font colors and background colors are used to identify the currently connected device. Then, the system returns to the channel switching identifier character detection logic to continue detecting data in real time.

[0040] This invention can solve the problem that the inability to display the devices connected by the shared serial port causes reduced performance of the storage controller, risk of data loss, and great trouble for research and development and maintenance. Attached Figure Description

[0051] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0052] As described in the background section, current storage control enclosures with four controllers per enclosure are gradually becoming a trend in high-end storage due to their robust reliability (four out of four fail). A four-controller enclosure means that four controllers (i.e., motherboards) are installed within a single chassis. Taking a current storage control enclosure as an example... Figure 1 and Figure 2 As shown.

[0053] in, Figure 1 This is the front view; the arrow indicates the controller. Figure 2 This is the rear view; the arrow indicates the shared serial port.

[0054] Each controller contains at least an x86 main operating system and a BMC management subsystem; some designs also include an FPGA system or a dedicated ASIC system. All of these systems need to provide external debugging serial ports for R&D and maintenance personnel.

[0055] As the number of controllers adapted within the frame reaches four, even with the controllers providing an X86 business main operating system and a BMC management subsystem, the total number of serial ports will reach eight.

[0056] from Figure 2 As shown in the image, the storage control box is highly integrated, and due to space limitations, only one serial port can usually be reserved on the chassis panel. Therefore, it is necessary for four controllers to share a single serial port.

[0057] Its implementation method is generally as follows: Figure 3 As shown.

[0058] like Figure 4 As shown, all serial ports are connected to the CPLD on the management module. The CPLD performs internal synthesis, implementing a switch similar to a single-pole eight-way switch. The user inputs special characters through the headphone jack to the CPLD, which then controls the toggle of the single-pole eight-way switch by recognizing different characters.

[0059] CPLD stands for Complex Programming Logic Device.

[0060] However, repeatedly switching between eight serial ports will inevitably lead to switching confusion. For example, the serial port output characters of the main operating system of Controller 1 and Controller 2 might be identical. When a user switches from Controller 1 to Controller 2, they cannot determine whether the switch was successful. Similarly, the user cannot know which controller the current serial port is connected to. Users can only determine this indirectly through other methods (such as checking the controller serial number or IP address). This will cause significant problems for development and maintenance, greatly reduce user-friendliness, and ultimately lead to a negative customer experience and criticism.

[0061] Example 1:

[0062] This invention provides a shared serial port identification method, which may include the following steps:

[0063] S510: Based on the preset channel switching identifier character detection logic, the running data is detected in real time to determine whether there is a channel switching identifier character input.

[0064] If the judgment result of real-time detection of running data based on the preset channel switching identifier character detection logic to determine whether there is a channel switching identifier character input is yes, then proceed to step S520.

[0065] In one implementation, the process of this step may include:

[0066] S511. Based on the RX input from the headphone jack and the preset channel switching identifier character, detect the running data to determine whether there is a channel switching identifier character input.

[0067] The RX input from the headphone jack is a channel switching identifier character.

[0068] In one embodiment, before step S510, which uses preset channel switching identifier character detection logic to detect running data in real time to determine whether a channel switching identifier character has been input, the method further includes:

[0069] Connect all serial ports to a complex programmable logic device to enable the configuration of a single-pole multi-throw switch.

[0070] In one embodiment, after step S510, which involves real-time detection of running data based on a preset channel switching identifier character detection logic to determine whether a channel switching identifier character has been input, the method further includes the following steps:

[0071] S1. Control the toggle of the single-pole multi-throw switch by recognizing the preset channel switching identifier character.

[0072] Specifically,

[0073] If the judgment result of real-time detection of running data based on preset channel switching identifier character detection logic to determine whether there is a channel switching identifier character input is yes, then the single-pole multi-throw switch is set to a floating state.

[0074] If the judgment result of real-time detection of running data based on the preset channel switching identifier character detection logic is negative, then return to the channel switching identifier character detection logic.

[0075] S520: Obtain the target channel number based on the input channel switching identifier character.

[0076] S530. Send the target channel number to the maintenance terminal and obtain the target font color setting command returned by the maintenance terminal based on the target channel number.

[0077] The maintenance terminal is a serial terminal software (such as xshell, TeraTerm, etc.) on the PC of the R&D and maintenance personnel.

[0078] When the serial terminal software (such as xshell, Tera Term, etc.) on the PCs of R&D and maintenance personnel receives the aforementioned characters sent from the debugging device, it will modify the display font color and font background color. The debugging device is a complex programmable logic device, i.e., a CPLD.

[0079] Down Figure 7 This is to demonstrate the effect after color adjustment.

[0080] S540. Modify the font color and background color of the corresponding identifier of the target channel based on the target font color setting command to distinguish each serial port channel.

[0081] The implementation process of step S540, which modifies the font color and background color of the corresponding identifier of the target channel based on the target font color setting command to distinguish each serial port channel, may include the following steps:

[0082] S541. Set the color control combination to: ESC character + character "[" + character "color code" + character "m".

[0083] Figure 7 This is a schematic diagram illustrating the effect of the shared serial port identification method provided in this embodiment of the invention. (Refer to...) Figure 7 As shown, the color codes are divided into characters 30-37 to set the font color and characters 40-47 to set the font background.

[0084] 30: Black 40: Black

[0085] 31: Red 41: Red

[0086] 32: Green 42: Green

[0087] 33: Yellow 43: Yellow

[0088] 34: Blue 44: Blue

[0089] 35: Purple 45: Purple

[0090] 36: Green 46: Green

[0091] 37: White 47: White

[0092] Use the serial port font color and font background color mentioned above to identify the currently connected device, for example:

[0093] White text on a black background indicates the serial port output of the controller 1-X86 business main operating system.

[0094] Blue text on a black background indicates the serial port output of the controller 1-BMC management subsystem.

[0095] White text with a green background indicates the serial port output of the controller 2-X86 business main operating system.

[0096] Blue text with a green background indicates the serial port output of the controller 2-BMC management subsystem.

[0097] White text with a yellow background indicates the serial port output of the controller's 3-X86 business main operating system.

[0098] Blue text with a yellow background indicates the serial port output of the controller 3-BMC management subsystem.

[0099] White text with a red background indicates the serial port output of the controller's 4-X86 business main operating system.

[0100] Blue text with a red background indicates the serial port output of the controller 4-BMC management subsystem.

[0101] The color control combination is then:

[0102] White text on a black background indicates the serial port output of the controller 1-X86 business main operating system.

[0103] ESC character (0x1b) + character "[" (0x5b) + character "color code" + character "m" (0x6d)

[0104] 0x1b 0x5b 0x33 0x37 0x6d / / Set font color

[0105] 0x1b 0x5b 0x340x400x6d / / Set font background color

[0106] Blue text on a black background indicates serial port output of the controller 1-BMC management subsystem.

[0107] ESC character (0x1b) + character "[" (0x5b) + character "color code" + character "m" (0x6d)

[0108] 0x1b 0x5b 0x33 0x34 0x6d / / Set font color

[0109] 0x1b 0x5b 0x340x400x6d / / Set font background color

[0110] White text with a green background indicates the serial port output of the controller 2-X86 business main operating system.

[0111] 0x1b 0x5b 0x33 0x37 0x6d / / Set font color

[0112] 0x1b 0x5b 0x34 0x4 20x6d / / Set font background color

[0113] Blue text with a green background indicates serial port output from the controller 2-BMC management subsystem.

[0114] 0x1b 0x5b 0x33 0x34 0x6d / / Set font color

[0115] 0x1b 0x5b 0x34 0x4 20x6d / / Set font background color

[0116] S542. Set the ASSIC character to hexadecimal or binary.

[0117] In one implementation, after step S540 modifies the font color and background color of the identifier corresponding to the target channel based on the target font color setting command to distinguish each serial port channel, the method further includes the following steps:

[0118] S2. Determine whether the font color and background color of the corresponding label for each channel have been modified.

[0119] S3, disable UART-send logic.

[0120] S4. Switch the single-pole multi-throw switch according to the target channel number.

[0121] In one implementation, step S540 is followed by:

[0122] S5, Return Channel Switching Identifier Character Detection Logic.
