Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present application.

[0021] It should be noted that in the description of the present application, the terms "include", "comprise" or any other variants thereof are intended to cover non - exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not explicitly listed, or further includes elements inherent to such a process, method, article or device. The terms "first", "second", etc. in the present application are used to distinguish similar objects and are not used to describe a specific order or sequence.

[0022] It should be noted that the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. The terms "mounted", "connected", and "coupled" should be understood in a broad sense.

For example, "parallel" includes absolute parallel and approximate parallel, where the acceptable deviation range for approximate parallel can be, for example, within 5° deviation; "perpendicular" includes absolute perpendicular and approximate perpendicular, where the acceptable deviation range for approximate perpendicular can also be, for example, within 5° deviation.

For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0023] To clearly understand the technical solution of the present application, the solutions of the prior art will be introduced in detail first. Figure 1 The structural schematic diagram of the server provided by the embodiment of the present application is as Figure 1As shown in the figure, the server structure includes a hard disk label, a hard disk tray, a hard disk backplane, a midplane, a disk array card tray, a motherboard, etc. The hard disk is installed in the hard disk tray, and the corresponding hard disk label is pasted according to the installed hard disk type. The hard disk tray is installed in the server chassis in a pull-out form. After being installed in place, each tray and the hard disk backplane have connectors to achieve interconnection. The hard disk backplane is interconnected with the midplane through a cable. At the same time, the blind plug connectors in the midplane are connected to the motherboard through cables. Here, the data cables connecting the midplane and the motherboard altogether include 6 cable connection ports (#1 - #6). Different combinations of the number of hard disks and different hard disk types will result in different interface positions of the cables connected to the midplane. The current practice is to apply for 6 material codes for the same cable at the same time, and guide the production line operation by defining the installation position of each code in the assembly instructions. However, during long-term manual operation, there is a risk of installation errors caused by misreading the cable code.

[0024] To solve the above technical problems, the inventor thought of setting a hard disk identification module at the position where the hard disk label is pasted on each hard disk tray. After the hard disk label is pasted, the corresponding path of the hard disk is conducted, and the hard disk information can be sent to the cable installation determination module. The signal conversion module corresponding to the hard disk identification module receives the hard disk information and converts it into a level signal, and transmits it to the decision-making module. The decision-making module generates a control signal according to each level signal, and controls the indication module installed beside the blind plug connector mounting seat to output the cable installation position indication information according to the control signal. After inserting the hard disk, the cable installation position identification system can automatically identify the internal cable installation position, eliminating the need for production line workers to check the codes of each cable one by one, view the installation position corresponding to this code in the assembly instructions and then perform the assembly, greatly saving the cable installation time in the production process, and at the same time reducing the risk of installation errors caused by misreading the cable code.

[0025] To enable those skilled in the art of this technology to better understand the solution of this application, the following further elaborates on this application in conjunction with the accompanying drawings and specific embodiments.

[0026] Refer to Figure 2 , Figure 2 which is the structural schematic Figure 1 of the cable installation position identification system provided by the embodiment of this application. Figure 2 As shown in the figure, the cable installation position identification system includes:

[0027] At least one cable installation position identification device 100.

[0028] The cable installation position recognition device 100 includes multiple hard disk trays 1, a cable installation determination module 2, and an indication module 3. Among them, a hard disk recognition module 4 is built into the pasting position of each hard disk tray 1. The cable installation determination module 2 includes multiple signal conversion modules 201 and a decision module 202. The indication module 3 is installed beside the blind plug connector mounting seat, and the blind plug connector mounting seat is used to install cables.

[0029] Among them, the hard disk tray 1 is a device for fixing and installing hard disks, providing stable mechanical support for the hard disks to ensure that the hard disks will not loosen or be damaged due to factors such as vibration during the operation of the device.

[0030] In this embodiment, the hard disk tray 1 is installed in the chassis of the server in a pull-out form. After being installed in place, each hard disk tray 1 and the hard disk backplane are interconnected by male and female connectors, which can accurately transmit data and ensure normal communication between the hard disk and other components of the server. The cable installation position recognition device provided in this application is independent of the normal data transmission function of the hard disk and does not interfere with each other. Among them, the male and female connectors are used to achieve electrical connection between two components.

[0031] In this embodiment, there is no electrical connection between the indication module 3 and the blind plug connector mounting seat, but the indication module 3 is installed adjacent to the blind plug connector mounting seat, and is used to provide cable installation indication for the blind plug connector mounting seat at the corresponding position. Among them, the blind plug connector mounting seat is a hardware component applied to various electronic devices, which can provide a stable and reliable connection platform for data cables and power cables.

[0032] Each hard disk recognition module 4 is electrically connected to the input end of the corresponding signal conversion module 201. The hard disk recognition module 4 is used to identify the hard disk label at the pasting position to obtain hard disk information and transmit the hard disk information to the corresponding signal conversion module 201.

[0033] The hard disk label is placed on the hard disk tray in a non-fixed manner.

[0034] There is a pre-buried wire on the back of the hard disk label, and the pre-buried wire is used to conduct the hard disk recognition module 4 after the hard disk is placed in the hard disk tray 1.

[0035] In this embodiment, the height positions of the wires on the back of the hard disk labels corresponding to different types of hard disks are different. Pasting different labels conducts different paths, and then the type and quantity of the hard disks installed on the hard disk tray are automatically recognized through the potential differences of different paths.

[0036] In this embodiment, each hard disk identification module 4 corresponds to a signal conversion module 201. Each hard disk identification module 4 is electrically connected to the input end of the corresponding signal conversion module 201. After a hard disk is placed in the hard disk tray 1, the hard disk label corresponding to the hard disk is pasted. At the same time, the path corresponding to the hard disk label is conducted in the hard disk identification module 4, and the hard disk information is transmitted to the corresponding signal conversion module 201 through the path.

[0037] The output end of each signal conversion module 201 is electrically connected to the input end of the decision-making module 202. The first output end of the decision-making module 202 is electrically connected to the indication module 3. The signal conversion module 201 is used to convert the hard disk information into a level signal and transmit it to the decision-making module 202. The decision-making module 202 generates a control signal according to each level signal and controls the indication module 3 to output cable installation position indication information according to the control signal.

[0038] In this embodiment, the output end of each signal conversion module 201 is electrically connected to the input end of the decision-making module 202. After each signal conversion module 201 receives the hard disk information sent by the corresponding hard disk identification module 4, it processes the hard disk information and converts it into a level signal, and transmits it to the decision-making module 202. The decision-making module 202 generates a control signal according to each level signal, where the control signal includes a trigger response signal and a state switching signal, and is transmitted through the two output ends of the decision-making module 202 respectively. The first output end for outputting the trigger response signal is electrically connected to the indication module 3, and the second output end for outputting the state switching signal can be left vacant or connected to other components. The indication module 3 outputs cable installation position indication information according to the received trigger response signal.

[0039] The working process of the cable installation position identification device provided in the above embodiment is as follows: Each hard disk identification module identifies the hard disk label at the pasting position, determines the hard disk information in the hard disk tray by conducting the path type and the number of paths of the hard disk identification module, and the hard disk identification module transmits the hard disk information to the corresponding signal conversion module. Each signal conversion module processes the hard disk information and converts it into a level signal, where the high level and the low level respectively represent different types of hard disks, and transmits all the level signals to the decision-making module. The decision-making module generates a control signal according to the number of high level signals and the number of low level signals, and controls the indication module to output cable installation position indication information according to the control signal.

[0040] As can be seen from the above embodiments, by adding a hard disk identification module inside the pasting position of the traditional hard disk bracket, the type and quantity of the installed hard disk can be identified. The cable installation determination module processes the hard disk information so that the hard disk information is converted into a control signal capable of controlling the indication module to give an indication. Each indication module is respectively installed beside the blind plug connector mounting seat for installing the cable, and can visually identify the position where the internal cable should be installed, eliminating the need for production line workers to check the encoding of each cable one by one during operation, referring to the installation position corresponding to this encoding in the assembly instruction manual and then assembling. This greatly saves the cable installation time in the production process and at the same time reduces the risk of installation errors caused by misreading the cable encoding.

[0041] Reference Figure 3 , Figure 3 is a schematic structural diagram of the cable installation position identification system provided by the embodiment of the present application Figure 2 , such as Figure 3 shown. On the basis of the above embodiments, it further includes a disk array card identification module 5.

[0042] The input end of the disk array card identification module 5 is connected to the second output end of the decision module 202, and the output end of the disk array card identification module 5 is electrically connected to the input end of the decision module 202 of another cable installation position identification device.

[0043] Among them, a disk array card is a method of storing the same data in different places of multiple hard disks. By placing the data on multiple hard disks, input / output operations can be overlapped in a balanced manner, improving performance.

[0044] In this embodiment, when the hard disk placed in the hard disk bracket is of a preset type, it needs to be connected to a disk array card, and the quantity of the disk array card will also affect the cable installation position.

[0045] In this embodiment, the input end of the disk array card identification module 5 is connected to the second output end of the decision module 202 to receive a status switching signal, and the output end of the disk array card identification module 5 is electrically connected to the input end of the decision module 202 of another cable installation position identification device.

[0046] The disk array card identification module 5 is used to transmit the installation status signal of the disk array card to the decision module 202 of another cable installation position identification device when the hard disk identification module 4 identifies a hard disk of a preset type; the decision module 202 of another cable installation position identification device generates a control signal according to each level signal and the installation status signal, and controls the indication module 3 to output cable installation position indication information according to the control signal.

[0047] Among them, the preset type of hard disk is a hard disk that requires the cooperation of a disk array card. Exemplarily, such as a SAS (Serial Attached SCSI) hard disk or a SATA (Serial Advanced Technology Attachment) hard disk.

[0048] The working process of the cable installation position recognition device provided by the above embodiment is as follows: When any hard disk recognition module recognizes that the hard disk label at the pasting position is of the preset type, according to the number of conduction loops, determine the types and quantities of all hard disks, and transmit the types and quantities of all hard disks to the corresponding signal conversion module. Each signal conversion module converts the types and quantities of all hard disks into level signals and transmits the level signals to the decision module. The decision module receives the installation status signal of the disk array card transmitted by the disk array card recognition module and the level signals of each signal conversion module, generates a control signal according to each level signal and the installation status signal, and controls the indication module to output cable installation position indication information according to the control signal.

[0049] As can be seen from the above embodiment, the disk array card recognition module is installed on the normal disk array card bracket and is only used to recognize whether the disk array card is installed, without affecting the original physical structure and function. When the hard disk recognition module recognizes a preset type of hard disk, the cooperation of the disk array card is required. The disk array card recognition module provided in this embodiment can jointly identify the cable installation position with the preset type of hard disk after the disk array card is installed, eliminating the need to check the encoding of each cable one by one during production line operations, and then checking the installation position corresponding to this encoding in the assembly instruction manual before assembly. It can greatly save the cable installation time in the production link.

[0050] Reference Figure 4 , Figure 4 is the structural schematic diagram of the cable installation position recognition system provided by the embodiment of the present application. Figure 3 As Figure 4 shown, taking the case of accommodating 4 hard disk brackets as an example, the hard disk recognition module 4 includes: a first type recognition path 401, a second type recognition path 402, and a first power supply 403.

[0051] In this embodiment, the first type recognition path 401 and the second type recognition path 402 share an input power supply.

[0052] The input end of the first type recognition path 401 is connected to the first power supply 403, and the output end of the first type recognition path 401 is electrically connected to the first input end of the corresponding signal conversion module 201.

[0053] Continue to refer to Figure 4, the first type of identification path 401 includes: a first contact switch 4011 and a first resistor 4012. The first contact switch 4011 is connected to the first power supply 403 and one end of the first resistor 4012, and the other end of the first resistor 4012 is connected to the first input end of the corresponding signal conversion module 201.

[0054] The input end of the second type of identification path 402 is connected to the first power supply 403, and the output end of the second type of identification path 402 is electrically connected to the second input end of the corresponding signal conversion module 201.

[0055] Continue to refer to Figure 4 , the second type of identification path 402 includes: a second contact switch 4021 and a second resistor 4022. The second contact switch 4021 is connected to the first power supply 403 and one end of the second resistor 4022, and the other end of the second resistor 4022 is connected to the second input end of the corresponding signal conversion module 201.

[0056] In this embodiment, the first type of identification path 401 and the second type of identification path 402 share an input source. Different resistance values of the first resistor 4012 and the second resistor 4022 will result in different potential voltage drops in the two paths, and then identify which type of hard disk is installed at each position and the number of each type of hard disk installed through different voltage drops.

[0057] Continue to refer to Figure 4 , the cable installation determination module 2 further includes: a second power supply 203. The second power supply 203 is connected to the input ends of the signal conversion modules 201 to provide a stable operating voltage for the signal conversion modules 201.

[0058] In this embodiment, the cable installation determination module 2 includes a signal conversion module 201 and a decision module 202.

[0059] Continue to refer to Figure 4 , the signal conversion module 201 includes: a first AND gate logic unit 2011. The first input end of the first AND gate logic unit 2011 is electrically connected to the output end of the first type of identification path 401; the second input end of the first AND gate logic unit 2011 is electrically connected to the output end of the second type of identification path 402; the third input end of the first AND gate logic unit 2011 is connected to the second power supply 203. The output end of the first AND gate logic unit 2011 is connected to the input end of the decision module 202.

[0060] The decision module 202 includes: a NOR gate logic unit 2021. The input end of the NOR gate logic unit 2021 is electrically connected to the output ends of the signal conversion modules 201. The first output end of the NOR gate logic unit 2021 is connected to the indication module 3.

[0061] Continue to refer to Figure 4, the indication module 3 includes: an indicator light 301. One end of the indicator light 301 is electrically connected to the first output end of the decision-making module 202, and the other end of the indicator light 301 is grounded. The indicator light 301 is installed in the form of a surface mount component beside the corresponding blind plug connector mount.

[0062] In this embodiment, when the indication module 3 indicates that a cable is installed on the corresponding blind plug connector mount, it can be constantly on or flashing.

[0063] In this embodiment, an indication switch is further included between the first output end of the decision-making module 202 and the indicator light 301. The indication switch is in a closed state by default. After a cable is installed on the blind plug connector mount corresponding to the indicator light 301, the production line worker disconnects the indication switch, causing the indicator light 301 to go out.

[0064] The working process of the above embodiment is as follows: Taking a hard disk tray that can accommodate 4 hard disks as an example, when a general type hard disk is installed in the hard disk tray, a general type hard disk label will be pasted on the corresponding hard disk tray. The general type hard disk refers to a hard disk that does not require the cooperation of a disk array card. Exemplarily, such as an NVME hard disk (Non-Volatile Memory Express, non-volatile memory host controller interface specification hard disk). After pasting the general type hard disk label, the first contact switch is connected, and at the same time, the first type recognition path is conducted. When the first power supply passes through the first resistor as the first input end of the first AND logic unit, the voltage at this time is the same as the voltage provided by the second power supply. At this time, since the second input end of the AND logic unit is connected to the second type recognition path, the second input end has no signal input and can be ignored. Both input ends of the first AND logic unit are at a high level, so the output end is at a high level. Therefore, the output end of the first AND logic unit is at a high level. When 1-4 general type hard disks are installed, all input ends of the NOR logic unit are at a high level. According to the characteristics of the NOR logic unit, the first output end outputs a high level, and the corresponding indicator light is lit at this time. At the same time, the second output end of the NOR logic unit outputs a low level.

[0065] Figure 5a It is a schematic diagram of the general type hard disk label provided by the embodiment of the present application. As Figure 5a shown, there are pre-buried wires on the back of the general type hard disk label. Figure 5b It is a schematic diagram of the preset type hard disk label provided by the embodiment of the present application. As Figure 5b shown, there are pre-buried wires on the back of the preset type hard disk label. In this embodiment, the positions of the pre-buried wires of the general type hard disk label and the preset type hard disk label are different.

[0066] In this embodiment, the back of the hard disk label may also be wires of different shapes. Exemplarily, the back of the general - type hard disk label includes triangular raised conduction contacts, and the back of the preset - type hard disk label includes square raised conduction contacts. The square raised conduction contacts can conduct the second - type identification path, and the triangular raised conduction contacts can conduct the first - type identification path. Moreover, the square raised conduction contacts and the triangular raised conduction contacts cannot conduct the first - type identification path and the second - type identification path simultaneously.

[0067] In summary, by adding a hard disk identification module inside the pasting position of the traditional hard disk bracket, the type and quantity of the installed hard disk can be identified. The cable installation determination module processes the hard disk information so that the hard disk information is converted into a control signal capable of controlling the indication module to give an indication. Each indication module is respectively installed beside the blind - plug connector mounting seat for installing the cable, and can visually identify the position where the internal cable should be installed, eliminating the need for production - line workers to check the coding of each cable one by one during operation, looking up the installation position corresponding to this coding in the assembly instruction manual and then assembling. This greatly saves the cable installation time in the production process and reduces the risk of installation errors caused by misreading the cable coding.

[0068] Reference Figure 6 , Figure 6 is the structural schematic diagram of the cable installation position identification system provided by the embodiment of the present application. Figure 4 As Figure 6 shown, taking two cable installation position identification devices as an example, the cable installation position identification system further includes a disk array card identification module 5. The disk array card identification module 5 includes: a third power supply 501, a loop switch 502, a third resistor 503, a fourth power supply 504, and a second AND - gate logic unit 505. The loop switch 502 is connected to one end of the third power supply 501 and the third resistor 503; the other end of the third resistor 503 is connected to the first input terminal of the second AND - gate logic unit 505; the second input terminal of the second AND - gate logic unit 505 is connected to the fourth power supply 504. The third input terminal of the second AND - gate logic unit 505 is electrically connected to the second output terminal of the decision - making module 202 for receiving the state - switching signal of the decision - making module 202. The output terminal of the second AND - gate logic unit 505 is electrically connected to the input terminal of the decision - making module 202 of another cable installation position identification device.

[0069] The working process of the above embodiment is as follows: Taking the example that each cable installation position identification device houses 4 hard disk trays, when a preset type of hard disk is installed in the hard disk tray, a preset type of hard disk label is pasted on the corresponding hard disk tray, where the preset type of hard disk refers to the hard disk that requires the cooperation of a disk array card. After pasting the preset type of hard disk label, the second contact switch is connected, and at the same time, the second type of identification path is turned on. When the first power supply passes through the second resistor as the second input terminal of the first AND logic unit, the voltage at this time is less than the voltage provided by the second power supply. At this time, since the first input terminal of the AND logic unit is connected to the first type of identification path, there is no signal input at the first input terminal and it can be ignored. There is a low level at the input terminal of the first AND logic unit, so a low level is output, and thus the output terminal of the first AND logic unit is at a low level. When 1 - 8 preset type hard disks are installed, the input terminals of the NOR logic unit are all at a low level. According to the characteristics of the NOR logic unit, the first output terminal outputs a low level, and the corresponding indicator light is not lit at this time. At the same time, the second output terminal of the NOR logic unit outputs a high level. The preset type of hard disk needs to be paired with a disk array card. After the disk array card is installed, the loop switch is automatically turned on. The voltage after the third power supply passes through the third resistor is the same as the voltage provided by the fourth power supply. At this time, all three inputs of the second AND logic unit are at a high level, so the output terminal of the second AND logic unit outputs a high level. At this time, there is a high level at the input of the decision module of another cable installation position identification device. Therefore, the first output terminal of the NOR logic unit of the cable installation position identification device outputs a high level, and the corresponding indicator light is lit at this time.

[0070] As can be seen from the above embodiment, the disk array card identification module is installed on the normal disk array card tray and is only used to identify whether the disk array card is installed, without affecting the original physical structure and function. When the hard disk identification module identifies a preset type of hard disk, the cooperation of the disk array card is required. The disk array card identification module provided in this embodiment can jointly identify the cable installation position with the preset type of hard disk after the disk array card is installed, eliminating the need to check the encoding of each cable one by one during the production line operation, and then checking the installation position corresponding to this encoding in the assembly manual and then assembling. It can greatly save the cable installation time in the production process.

[0071] Figure 7 FIG. 5 is a schematic structural diagram of the cable installation position identification system provided by the embodiment of the present application, as Figure 7As shown, taking 24 hard disk trays corresponding to 6 blind plug connector mounts as an example, different types and quantities of hard disks need to install cables on different blind plug connector mounts. The cable installation position identification devices are, from left to right and from top to bottom in sequence, the first cable installation position identification device, the second cable installation position identification device, the third cable installation position identification device, the fourth cable installation position identification device, the fifth cable installation position identification device, and the sixth cable installation position identification device. Each cable installation position identification device accommodates 4 hard disk trays, and each indication module corresponds to #①, #②, #③, #④, #⑤, #⑥ respectively.

[0072] In this embodiment, when 1 - 8 preset type hard disks and 1 - 4 general type hard disks are installed in the hard disk trays, based on the hard disk mixing rule, the preset type hard disks are installed starting from the first cable installation position identification device backward, and the general type hard disks are installed forward in sequence starting from the sixth cable installation position identification device. The preset type hard disks are installed in the hard disk tray positions of the first 2 cable installation position identification devices, and the general type hard disks are installed in the hard disk tray positions of the sixth cable installation position identification device. When the preset type hard disks are installed in the hard disk tray positions of the first 2 cable installation position identification devices, the second type identification paths of each hard disk identification module are conducted. Since the first AND gate logic unit has a low - level input, it outputs a low level to the NOR gate logic unit. The NOR gate logic unit outputs a low level, resulting in #① not lighting up. At the same time, a high - level signal is transmitted to the second AND gate logic unit of the disk array card identification module. After the disk array card is installed, the second AND gate logic unit outputs a high - level signal, making the input of the NOR gate logic unit of the second cable installation position identification device include a high - level signal. Therefore, this NOR gate logic unit outputs a high level, thus making #② light up. When the general type hard disks are installed in the hard disk tray positions of the sixth cable installation position identification device, the first type identification path is conducted, and the first AND gate logic unit outputs a high - level signal, making #⑥ light up.

[0073] In this embodiment, when 1 - 8 hard disks of a preset type are installed in the hard disk tray and 5 - 8 hard disks of a general type are installed simultaneously, the hard disks of the preset type are installed in the hard disk tray positions of the first 2 cable installation position identification devices, and the hard disks of the general type are installed in the hard disk tray positions of the last 2 cable installation position identification devices. Installing the hard disks of the preset type in the hard disk tray positions of the first 2 cable installation position identification devices conducts the second type of identification path of each hard disk identification module. Since the first AND logic unit has a low - level input, it outputs a low level to the NOR logic unit. The NOR logic unit outputs a low level, causing #① not to light up. At the same time, a high - level signal is transmitted to the second AND logic unit of the disk array card identification module. After the disk array card is installed, the second AND logic unit outputs a high - level signal, making the input of the NOR logic unit of the second cable installation position identification device include a high - level signal. Therefore, this NOR logic unit outputs a high level, causing #② to light up. Installing the hard disks of the general type in the hard disk tray positions of the last 2 cable installation position identification devices conducts the first type of identification path, and the first AND logic unit outputs a high - level signal, causing #⑤ and #⑥ to light up.

[0074] In this embodiment, when 1 - 8 hard disks of a preset type are installed in the hard disk tray and 9 - 12 hard disks of a general type are installed simultaneously, the hard disks of the preset type are installed in the hard disk tray positions of the first 2 cable installation position identification devices, and the hard disks of the general type are installed in the hard disk tray positions of the last 3 cable installation position identification devices. Installing the hard disks of the preset type in the hard disk tray positions of the first 2 cable installation position identification devices conducts the second type of identification path of each hard disk identification module. Since the first AND logic unit has a low - level input, it outputs a low level to the NOR logic unit. The NOR logic unit outputs a low level, causing #① not to light up. At the same time, a high - level signal is transmitted to the second AND logic unit of the disk array card identification module. After the disk array card is installed, the second AND logic unit outputs a high - level signal, making the input of the NOR logic unit of the second cable installation position identification device include a high - level signal. Therefore, this NOR logic unit outputs a high level, causing #② to light up. Installing the hard disks of the general type in the hard disk tray positions of the last 3 cable installation position identification devices conducts the first type of identification path, and the first AND logic unit outputs a high - level signal, causing #④, #⑤, and #⑥ to light up.

[0075] In this embodiment, when 9 - 12 hard disks of a preset type and 1 - 4 hard disks of a general type are installed in the hard disk tray, if a disk array card supporting 16 hard disks is used, only 1 disk array card identification module is required. The hard disks of the preset type are installed in the hard disk tray positions of the first 3 cable installation position identification devices, and the hard disks of the general type are installed in the hard disk tray positions of the last 1 cable installation position identification device. Among the first 3 cable installation position identification devices, the disk array card identification module is connected to the first cable installation position identification device and the second cable installation position identification device, then #① is not lit, #② is lit, #③ is not lit. The hard disks of the general type are installed in the hard disk tray positions of the last 1 cable installation position identification device, enabling the first type of identification path to conduct, and the first AND logic unit outputs a high - level signal, causing #⑥ to be lit.

[0076] In this embodiment, when 13 - 16 hard disks of a preset type are installed in the hard disk tray, if a disk array card supporting 8 hard disks is used, 2 disk array card identification modules are required. The hard disks of the preset type are installed in the hard disk tray positions of the first 4 cable installation position identification devices, then #② is lit and #⑤ is lit.

[0077] Table 1 shows the installation rules of the cable coding in the assembly instruction provided by the embodiment of the present application. As shown in Table 1, taking 24 hard disk trays corresponding to 6 blind - plug connector mounts as an example, different types and quantities of hard disks need to install cables on different blind - plug connector mounts.

[0079]

[0080] In summary, by adding a hard disk identification module inside the pasting position of the hard disk tray, the type and quantity of the installed hard disks can be identified. The cable installation determination module processes the hard disk information to convert it into a control signal capable of controlling the indication module for indication. Each indication module is respectively installed beside the blind - plug connector mount for installing the cable, which can visually identify the position where the internal cable should be installed, eliminating the need to refer to the installation rules of the cable coding in the assembly instruction, greatly saving the cable installation time in the production process and reducing the risk of installation errors caused by misreading the cable coding.

[0081] Figure 8 It is a schematic flowchart of the cable installation position identification method provided by the embodiment of the present application. As Figure 6 shown, the method includes:

[0082] S801: Each hard disk identification module identifies the hard disk label at the pasting position, obtains the hard disk information, and transmits the hard disk information to the corresponding signal conversion module.

[0083] Specifically, each hard disk identification module identifies the hard disk label at the pasting position, determines the hard disk information in the hard disk tray by conducting the path type and the number of paths of the hard disk identification module, and the hard disk identification module transmits the hard disk information to the corresponding signal conversion module.

[0084] Specifically, the hard disk identification module includes: a first type identification path, a second type identification path, and a first power supply. The input end of the first type identification path is connected to the first power supply, and the output end of the first type identification path is electrically connected to the first input end of the corresponding signal conversion module. The input end of the second type identification path is connected to the first power supply, and the output end of the second type identification path is electrically connected to the second input end of the corresponding signal conversion module. Among them, the first type identification path includes: a first contact switch and a first resistor. The first contact switch is connected to the first power supply and one end of the first resistor, and the other end of the first resistor is connected to the first input end of the corresponding signal conversion module. The second type identification path includes: a second contact switch and a second resistor. The second contact switch is connected to the first power supply and one end of the second resistor, and the other end of the second resistor is connected to the second input end of the corresponding signal conversion module.

[0085] Specifically, when each hard disk identification module identifies that the hard disk label indicates a general type hard disk, it turns on the first contact switch or the second contact switch, thereby conducting the identification path. The hard disk identification module determines the hard disk information according to the characteristics of the first type identification path or the second identification path, and transmits the hard disk information to the corresponding signal conversion module.

[0086] S802: Each signal conversion module converts the hard disk information into a level signal and transmits the level signal to the decision module.

[0087] Specifically, each signal conversion module processes the hard disk information and converts it into a level signal, where high level and low level respectively represent different types of hard disks, and transmits all the level signals to the decision module.

[0088] Specifically, the cable installation determination module includes a signal conversion module, a decision module, and a second power supply. The signal conversion module includes: a first AND gate logic unit. The first input end of the first AND gate logic unit is electrically connected to the output end of the first type identification path; the second input end of the first AND gate logic unit is electrically connected to the output end of the second type identification path; the third input end of the first AND gate logic unit is connected to the second power supply.

[0089] Specifically, each first AND gate logic unit outputs a high level or a low level according to the characteristics of the input voltage as the input of the decision module.

[0090] S803: The decision-making module generates a control signal based on each level signal, and controls the indication module to output cable installation position indication information according to the control signal.

[0091] Specifically, the decision-making module generates a control signal according to the number of high-level signals and the number of low-level signals, and controls the indication module to output cable installation position indication information according to the control signal.

[0092] Specifically, the indication module includes: an indicator light. One end of the indicator light is electrically connected to the first output end of the decision-making module, and the other end of the indicator light is grounded. The indicator light is installed in the form of a surface mount component beside the corresponding blind plug connector mount. When a high level is input to one end of the indicator light, a voltage difference is formed with the grounded end of the indicator light, so that the indicator light is lit. When a low level is output from one end of the indicator light and the voltage is the same as that of the grounded end of the indicator light, the indicator light is not lit.

[0093] In summary, by adding a hard disk identification module inside the pasting position of the traditional hard disk bracket, the type and quantity of the installed hard disk can be identified. The cable installation determination module processes the hard disk information so that the hard disk information is converted into a control signal capable of controlling the indication module for indication. Each indication module is respectively installed beside the blind plug connector mount for installing the cable, which can visually identify the position where the internal cable should be installed, eliminating the need for production line workers to check the coding of each cable one by one during operation, view the installation position corresponding to this coding in the assembly manual and then perform the assembly, greatly saving the cable installation time in the production process, and at the same time reducing the risk of installation errors caused by misreading the cable coding.

[0094] For the cable installation position recognition method that requires the participation of a disk array card, the cable installation position recognition system further includes a disk array card recognition module; the input end of the disk array card recognition module is connected to the second output end of the decision-making module, and the output end of the disk array card recognition module is electrically connected to the input end of the decision-making module of another cable installation position recognition device; the method further includes:

[0095] 901: When any hard disk identification module recognizes that the hard disk label at the pasting position is of a preset type, obtain the preset type hard disk information and transmit the preset type hard disk information to the corresponding signal conversion module.

[0096] Specifically, when any hard disk identification module recognizes that the hard disk label at the pasting position is of a preset type, determine the type and quantity of all hard disks according to the number of conduction loops, and transmit the type and quantity of all hard disks to the corresponding signal conversion module.

[0097] Specifically, the disk array card recognition module includes: a third power supply, a loop switch, a third resistor, a fourth power supply, and a second AND logic unit. The loop switch is connected to the third power supply and one end of the third resistor; the other end of the third resistor is connected to the first input terminal of the second AND logic unit; the second input terminal of the second AND logic unit is connected to the fourth power supply. The third input terminal of the second AND logic unit is electrically connected to the second output terminal of the decision module for receiving the status switching signal of the decision module. The output terminal of the second AND logic unit is electrically connected to the input terminal of the decision module of another cable installation position recognition device.

[0098] 902: Each signal conversion module converts the preset type hard disk information into a level signal and transmits the level signal to the decision module.

[0099] Specifically, each signal conversion module converts the type and quantity of all hard disks into a level signal and transmits the level signal to the decision module.

[0100] 903: The decision module receives the installation status signal of the disk array card transmitted by the disk array card recognition module, generates a control signal according to each level signal and the installation status signal, and controls the indication module to output the cable installation position indication information according to the control signal.

[0101] Specifically, the decision module receives the installation status signal of the disk array card transmitted by the disk array card recognition module and the level signals of each signal conversion module, generates a control signal according to each level signal and the installation status signal, and controls the indication module to output the cable installation position indication information according to the control signal.

[0102] Specifically, when a preset type hard disk is installed in the hard disk tray, a preset type hard disk label will be pasted on the corresponding hard disk tray, where the preset type hard disk refers to the hard disk that requires the cooperation of the disk array card. After pasting the preset type hard disk label, if the quantity of the preset type hard disks requires one disk array card, the disk array card recognition module is set between two cable installation position recognition devices. The disk array card recognition module receives the status switching signal output by the second output terminal of the first cable installation position recognition device, and after being processed by the second AND logic unit, it is sent to the decision module of the second cable installation position recognition device, so that the NOR logic unit of the second cable installation position recognition device processes all the level signals and the installation status signal of the disk array card recognition module, and outputs a control signal for controlling the second indication module.

[0103] In summary, the disk array card recognition module is installed on the normal disk array card bracket, which is only used to recognize whether the disk array card is installed and does not affect the original physical structure and function. When the hard disk recognition module recognizes a hard disk of a preset type, the cooperation of the disk array card is required. The disk array card recognition module provided in this embodiment can, after the disk array card is installed, jointly identify the installation positions of the cables with the hard disk of the preset type, eliminating the need to check the codes of each cable one by one during production line operations, and then referring to the assembly instructions to find the installation positions corresponding to these codes before assembly. This can greatly save the cable installation time in the production process.
