Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] It should be noted that the terms "center", "longitudinal", "lateral", "length", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are 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, and therefore cannot be understood as limiting the present application. The terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. The terms "parallel", "perpendicular" and "equal" include the situations described and situations similar to the situations described, and the range of the similar situations is within the acceptable deviation range, where the acceptable deviation range is determined by a person of ordinary skill in the art taking into account the measurement being discussed and the errors associated with the measurement of a specific quantity (i.e., the limitations of the measurement system). For example, "parallel" includes absolute parallelism and approximate parallelism, wherein the acceptable deviation range of approximate parallelism can be, for example, a deviation within 5°; "perpendicular" includes absolute perpendicularity and approximate perpendicularity, wherein the acceptable deviation range of approximate perpendicularity can also be, for example, a deviation within 5°. "Equal" includes absolute equality and approximate equality, wherein the acceptable deviation range of approximate equality can be, for example, that the difference between the two equals is less than or equal to 5% of either one. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0023] In order to clearly understand the technical solution of the present application, the solution of the prior art is first introduced in detail. Figure 1 A schematic diagram of the structure of the server provided in the embodiment of the present application, such as Figure 1As shown in the figure, the server structure includes a hard disk label, a hard disk bracket, a hard disk backplane, a mid-backplane, a disk array card tray, a motherboard, etc. The hard disk is installed in the hard disk bracket, and the hard disk is affixed with the corresponding hard disk label according to the type of hard disk installed. The hard disk bracket is installed in the server chassis by pulling it out. After installation, each bracket and the hard disk backplane are interconnected by a connector. The hard disk backplane is interconnected with the mid-backplane through a cable. At the same time, the blind plug connector in the mid-backplane is connected to the motherboard through a cable. Here, the data cable connecting the mid-backplane and the motherboard contains a total of 6 cable connection ports (#1-#6). Different numbers of hard disks and different combinations of hard disk types will result in different interface positions of the cable connection on the mid-backplane. 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 manual. However, long-term manual work is prone to the risk of misreading the cable code and causing installation errors.

[0024] In order to solve the above technical problems, the inventors have come up with the idea of ​​setting a hard disk identification module at the location where the hard disk label is pasted on each hard disk bracket. After the hard disk label is pasted, the path corresponding to the hard disk is turned on, 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 module. The decision module generates a control signal according to each level signal, and controls the indication module installed next to the blind plug connector mounting seat to output the cable installation position indication information according to the control signal. After the hard disk is inserted, the cable installation position identification system can automatically identify the internal cable installation position, eliminating the need for production line workers to check the code of each cable one by one, check the assembly manual for the installation position corresponding to this code, and then assemble it. 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 code.

[0025] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] refer to Figure 2 , Figure 2 A schematic diagram of the structure of the cable installation position identification system provided in the embodiment of the present application Figure 1 .like Figure 2 As shown, the cable installation position identification system includes:

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

[0028] The cable installation position identification device 100 includes a plurality of hard disk brackets 1, a cable installation determination module 2 and an indication module 3. The attachment position of each hard disk bracket 1 has a built-in hard disk identification module 4, the cable installation determination module 2 includes a plurality of signal conversion modules 201 and a decision module 202, and the indication module 3 is installed next to a blind-plug connector mounting seat, and the blind-plug connector mounting seat is used to install cables.

[0029] The hard disk bracket 1 is a device for fixing and installing the hard disk, providing stable mechanical support for the hard disk, and ensuring that the hard disk will not become loose or damaged due to factors such as vibration during the operation of the device.

[0030] In this embodiment, the hard disk bracket 1 is installed in the chassis of the server by pulling out. After installation, each hard disk bracket 1 and the hard disk backplane are interconnected by male and female connectors, which can accurately transmit data and ensure the normal communication between the hard disk and other components of the server. The cable installation position identification device provided by the present application and the normal data transmission function of the hard disk are independent of each other and do not interfere with each other. Among them, the male and female connectors are used to realize the electrical connection between the 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 to provide cable installation instructions for the blind-plug connector mounting seat at the corresponding position. The blind-plug connector mounting seat is a hardware component used in various electronic devices, which can provide a stable and reliable connection platform for data cables and power cables.

[0032] Each hard disk identification module 4 is electrically connected to the input end of the corresponding signal conversion module 201 . The hard disk identification 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 drive label is placed on the hard drive bracket 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 identification module 4 after the hard disk is placed in the hard disk bracket 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. Different labels are attached to different paths, and then the type and quantity of hard disks installed on the hard disk bracket are automatically identified through the high and low potential differences of different paths.

[0036] In this embodiment, each hard disk identification module 4 corresponds to a signal conversion module 201, and each hard disk identification module 4 is electrically connected to the input end of the corresponding signal conversion module 201. After the hard disk is placed in the hard disk bracket 1, the hard disk label corresponding to the hard disk is pasted, and at the same time, the path corresponding to the hard disk label is turned on 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 module 202, and the first output end of the decision 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 module 202. The decision module 202 generates a control signal according to each level signal, and controls the indication module 3 to output the 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 module 202. After each signal conversion module 201 receives the hard disk information sent by the corresponding hard disk identification module 4, the hard disk information is processed and converted into a level signal, and transmitted to the decision module 202. The decision module 202 generates a control signal according to each level signal, wherein the control signal includes a trigger response signal and a state switching signal, and is transmitted through the two output ends of the decision module 202 respectively, wherein 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 vacant or connected to other components. The indication module 3 outputs the 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 bracket by connecting 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 represent different types of hard disks, and transmits all the level signals to the decision module. The decision 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 the cable installation position indication information according to the control signal.

[0040] It can be seen from the above embodiments that 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 judgment module processes the hard disk information so that the hard disk information is converted into a control signal that can control the indication module to indicate. Each indication module is installed next to the blind plug connector mounting seat for installing cables, which can intuitively mark the position where the internal cable should be installed, eliminating the need for production line workers to check the code of each cable one by one during operation, check the assembly manual for the installation position corresponding to the code, and then assemble. This greatly saves the cable installation time in the production process, and at the same time reduces the risk of installation errors due to misreading the cable code.

[0041] refer to Figure 3 , Figure 3 A schematic diagram of the structure of the cable installation position identification system provided in the embodiment of the present application Figure 2 ,like Figure 3 As shown, based on the above embodiment, a disk array card identification module 5 is further included.

[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, disk array cards are a method of storing the same data in different places on multiple hard disks. By placing data on multiple hard disks, input and 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 number of disk array cards 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 the state 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 preset type of hard disk; the decision module 202 of the other 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 the cable installation position indication information according to the control signal.

[0047] The preset type of hard disk is a hard disk that requires the cooperation of a disk array card, such as, for example, 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 identification device provided in the above embodiment is as follows: when any hard disk identification module identifies that the hard disk label at the pasting position is of a preset type, the types and quantities of all hard disks are determined according to the number of conductive loops, and the types and quantities of all hard disks are transmitted 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 identification 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.

[0049] It can be seen from the above embodiments that the disk array card identification module is installed on a normal disk array card bracket and is only used to identify whether the disk array card is installed, and does not affect the original physical structure and function. When the hard disk identification module identifies the preset type of hard disk, the disk array card needs to participate in cooperation. The disk array card identification module provided in this embodiment can identify the cable installation position together with the preset type of hard disk after the disk array card is installed, eliminating the need to check the code of each cable one by one during production line operation, and then check the assembly manual for the installation position corresponding to this code before assembly. It can greatly save the cable installation time in the production process.

[0050] refer to Figure 4 , Figure 4 A schematic diagram of the structure of the cable installation position identification system provided in the embodiment of the present application Figure 3 .like Figure 4 As shown, taking the case of accommodating four hard disk trays as an example, the hard disk identification module 4 includes: a first type identification path 401 , a second type identification path 402 and a first power supply 403 .

[0051] In this embodiment, the first type identification path 401 and the second type identification path 402 share a common input power source.

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

[0053] Continue to refer Figure 4The first type identification path 401 includes: a first contact switch 4011 and a first resistor 4012. The first contact switch 4011 connects 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] An input end of the second type identification path 402 is connected to the first power supply 403 , and an output end of the second type identification path 402 is electrically connected to a second input end of the corresponding signal conversion module 201 .

[0055] Continue to refer Figure 4 The second type 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 identification path 401 and the second type identification path 402 share an input source, and the first resistor 4012 and the second resistor 4022 have different resistance values, which will cause the two paths to produce different potential voltage drops, and then identify the type of hard disk installed in each position and the number of each hard disk installed through different voltage drops.

[0057] Continue to refer 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 end of each signal conversion module 201, and is used to provide a stable working voltage to each signal conversion module 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 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 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 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 end of each signal conversion module 201. The first output end of the NOR gate logic unit 2021 is connected to the indication module 3.

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

[0062] In this embodiment, the indication module 3 may stay on or flash when indicating the corresponding blind-mate connector mounting seat to install a cable.

[0063] In this embodiment, an indicator switch is also included between the first output end of the decision module 202 and the indicator light 301, wherein the indicator switch is in a closed state by default. After the cable is installed in the blind-plug connector mounting socket corresponding to the indicator light 301, the production line worker disconnects the indicator switch to turn off the indicator light 301.

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

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

[0066] In this embodiment, the back of the hard disk label can also be a conductor of different shapes. For example, the back of the general type hard disk label includes a triangular raised conductive contact, and the back of the preset type hard disk label includes a square raised conductive contact. The square raised conductive contact can conduct the second type of identification path, and the triangular raised conductive contact can conduct the first type of identification path, and the square raised conductive contact and the triangular raised conductive contact cannot conduct the first type of identification path and the second type of identification path at the same time.

[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 judgment module processes the hard disk information so that the hard disk information is converted into a control signal that can control the indication module to indicate. Each indication module is installed next to the blind-plug connector mounting seat for installing cables. It can intuitively mark the position where the internal cables should be installed, eliminating the need for production line workers to check the codes of each cable one by one, check the assembly manual for the installation position corresponding to the code, and then assemble. This greatly saves the cable installation time in the production process and reduces the risk of installation errors due to misreading the cable code.

[0068] refer to Figure 6 , Figure 6 A schematic diagram of the structure of the cable installation position identification system provided in the embodiment of the present application Figure 4 . As shown in FIG5 , 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 connects the third power supply 501 and one end of the third resistor 503; the other end of the third resistor 503 is connected to the first input end of the second AND gate logic unit 505; the second input end of the second AND gate logic unit 505 is connected to the fourth power supply 504. The third input end of the second AND gate logic unit 505 is electrically connected to the second output end of the decision module 202, for receiving a state switching signal of the decision module 202. The output end of the second AND gate logic unit 505 is electrically connected to the input end of the decision module 202 of another cable installation position identification device.

[0069] The workflow of the above embodiment is as follows: taking the case that each cable installation position identification device accommodates 4 hard disk trays as an example, when a preset type of hard disk is installed in the hard disk tray, a preset type of hard disk label will be pasted on the corresponding hard disk tray, wherein the preset type of hard disk indicates a hard disk that requires the disk array card to cooperate. After pasting the preset type of hard disk label, the second contact switch is connected, and the second type identification path is turned on at the same time. When the first power supply passes through the second resistor as the second input end of the first AND gate logic unit, the voltage at this time is less than the voltage provided by the second power supply. At this time, the first input end of the AND gate logic unit is connected to the first type of identification path, so the first input end has no signal input and can be ignored. The input end of the first AND gate logic unit has a low level, and the output is a low level, so the output end of the first AND gate logic unit is a low level. When 1-8 preset types of hard disks are installed, the input ends of the NOR gate logic unit are all low levels. According to the characteristics of the NOR gate logic unit, the first output end outputs a low level, and the corresponding indicator light is off at this time. At the same time, the second output end of the NOR gate logic unit outputs a high level. The preset type of hard disk needs to be matched with a disk array card. After the disk array card is installed, the circuit switch is automatically turned on. The voltage of the third power supply after passing through the third resistor is the same as the voltage provided by the fourth power supply. At this time, the three inputs of the second AND gate logic unit are all high level, so the output end of the second AND gate logic unit outputs a high level. At this time, the input of the decision module of another cable installation position identification device has a high level, so the first output end of the NOR gate logic unit of the cable installation position identification device outputs a high level, and the corresponding indicator light is on.

[0070] It can be seen from the above embodiments that the disk array card identification module is installed on a normal disk array card bracket and is only used to identify whether the disk array card is installed, and does not affect the original physical structure and function. When the hard disk identification module identifies the preset type of hard disk, the disk array card needs to participate in cooperation. The disk array card identification module provided in this embodiment can identify the cable installation position together with the preset type of hard disk after the disk array card is installed, eliminating the need to check the code of each cable one by one during production line operation, and then check the assembly manual for the installation position corresponding to this code before assembly. It can greatly save the cable installation time in the production process.

[0071] Figure 7 A structural diagram 5 of the cable installation position identification system provided in an embodiment of the present application is as follows: Figure 7As shown, taking 24 hard disk trays corresponding to 6 blind-plug connector mounting seats as an example, different types and quantities of hard disks need to install cables on different blind-plug connector mounting seats, and the cable installation position identification devices are 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 from left to right and from top to bottom. Each cable installation position identification device accommodates 4 hard disk trays, and each indicator module corresponds to #①, #②, #③, #④, #⑤, and #⑥ respectively.

[0072] In this embodiment, when 1-8 preset type hard disks are installed in the hard disk bracket and 1-4 universal type hard disks are installed at the same time, based on the hard disk mixing rule, the preset type hard disk is installed from the first cable installation position identification device to the back, and the universal type hard disk is installed from the sixth cable installation position identification device to the front. The preset type hard disk is installed in the hard disk bracket position of the first two cable installation position identification devices, and the universal type hard disk is installed in the hard disk bracket position of the sixth cable installation position identification device. The preset type hard disk is installed in the hard disk bracket position of the first two cable installation position identification devices, and the second type identification path of each hard disk identification module is turned on. The first AND gate logic unit has a low level input, so it outputs a low level to the NOR gate logic unit. The NOR gate logic unit outputs a low level, causing #① to not light up, and at the same time transmits a high level signal 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, so that the input of the NOR gate logic unit of the second cable installation position identification device includes a high level signal, so the NOR gate logic unit outputs a high level, thereby making #② light up. A universal type hard disk is installed at the hard disk bracket position of the sixth cable installation position identification device, so that the first type identification path is turned on, and the first AND gate logic unit outputs a high level signal, so that #⑥ lights up.

[0073] In this embodiment, when 1-8 preset type hard disks are installed in the hard disk tray and 5-8 universal type hard disks are installed at the same time, the preset type hard disks are installed at the hard disk tray positions of the first two cable installation position identification devices, and the universal type hard disks are installed at the hard disk tray positions of the last two cable installation position identification devices. The preset type hard disks are installed at the hard disk tray positions of the first two cable installation position identification devices, and the second type identification path of each hard disk identification module is turned on. The first AND gate logic unit has a low level input, so it outputs a low level to the NOR gate logic unit. The NOR gate logic unit outputs a low level, causing #① not to light up, and at the same time transmits a high level signal 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, so that the input of the NOR gate logic unit of the second cable installation position identification device includes a high level signal, so the NOR gate logic unit outputs a high level, thereby causing #② to light up. The hard disk brackets of the last two cable installation position identification devices are installed with universal type hard disks, so that the first type identification path is turned on, and the first AND gate logic unit outputs a high level signal, so that #⑤ and #⑥ light up.

[0074] In this embodiment, when 1-8 preset type hard disks are installed in the hard disk tray and 9-12 universal type hard disks are installed at the same time, the preset type hard disks are installed at the hard disk tray positions of the first two cable installation position identification devices, and the universal type hard disks are installed at the hard disk tray positions of the last three cable installation position identification devices. The preset type hard disks are installed at the hard disk tray positions of the first two cable installation position identification devices, and the second type identification path of each hard disk identification module is turned on. The first AND gate logic unit has a low level input, so it outputs a low level to the NOR gate logic unit. The NOR gate logic unit outputs a low level, causing #① not to light up, and at the same time transmits a high level signal 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, so that the input of the NOR gate logic unit of the second cable installation position identification device includes a high level signal, so the NOR gate logic unit outputs a high level, thereby causing #② to light up. The hard disk bracket positions of the last three cable installation position identification devices are installed with universal type hard disks, so that the first type identification path is turned on, and the first AND gate logic unit outputs a high level signal, so that #④, #⑤, and #⑥ light up.

[0075] In this embodiment, when 9-12 preset type hard disks are installed in the hard disk tray and 1-4 universal type hard disks are installed at the same time, if a disk array card that supports 16 hard disks is used, only one disk array card identification module is needed, and the preset type hard disks are installed in the hard disk tray positions of the first three cable installation position identification devices, and the universal type hard disks are installed in the hard disk tray position of the last cable installation position identification device. In the first three cable installation position identification devices, the disk array card identification module connects 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, and the universal type hard disk is installed in the hard disk tray position of the last cable installation position identification device, so that the first type identification path is turned on, and the first AND gate logic unit outputs a high level signal, so that #⑥ is lit.

[0076] In this embodiment, when 13-16 preset type hard disks 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 preset type hard disks 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 is the cable coding installation rules of the assembly instructions provided in the embodiment of the present application. As shown in Table 1, taking 24 hard disk trays corresponding to 6 blind-plug connector mounting seats as an example, different types and quantities of hard disks require cables to be installed on different blind-plug connector mounting seats.

[0079]

[0080] In summary, by adding a hard disk identification module inside the pasting position of the hard disk bracket, the type and quantity of the installed hard disk can be identified. The cable installation judgment module processes the hard disk information so that the hard disk information is converted into a control signal that can control the indication module to indicate. Each indication module is installed next to the blind plug connector mounting seat for installing cables. It can intuitively mark the position where the internal cable should be installed. There is no need to compare the cable coding installation rules in the control installation manual, which greatly saves the cable installation time in the production process and reduces the risk of installation errors due to misreading the cable coding.

[0081] Figure 8 The following is a flow chart of a cable installation position identification method provided in an embodiment of the present application. Figure 6 As shown, the method includes:

[0082] S801: Each hard disk identification module identifies the hard disk label at the pasting position, obtains 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 bracket by connecting the path type and path number 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 connects 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 connects 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 recognizes that the hard disk label indicates a universal type of hard disk, it turns on the first contact switch or the second contact switch, thereby turning on the identification path. The hard disk identification module determines the hard disk information based on 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, wherein a high level and a low level represent different types of hard disks, respectively, 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.

The input end of the NOR gate logic unit is electrically connected to the output end of each signal conversion module. The first output end of the NOR gate logic unit is connected to the indication module.

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

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

[0091] Specifically, the decision 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 the 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 module, and the other end of the indicator light is grounded. The indicator light is installed next to the corresponding blind-plug connector mounting seat in the form of a patch component. When a high level is input to one end of the indicator light, a voltage difference is formed with the ground end of the indicator light, so that the indicator light is lit; when a low level is output to one end of the indicator light, which is the same as the voltage of the ground 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 judgment module processes the hard disk information so that the hard disk information is converted into a control signal that can control the indication module to indicate. Each indication module is installed next to the blind-plug connector mounting seat for installing cables. It can intuitively mark the position where the internal cables should be installed, eliminating the need for production line workers to check the codes of each cable one by one, check the assembly manual for the installation position corresponding to the code, and then assemble. This greatly saves the cable installation time in the production process and reduces the risk of installation errors due to misreading the cable code.

[0094] For the cable installation position identification method requiring the disk array card to cooperate, the cable installation position identification system also includes a disk array card identification module; the input end of the disk array card identification module is connected to the second output end of the decision module, and the output end of the disk array card identification module is electrically connected to the input end of the decision module of another cable installation position identification device; the method also includes:

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

[0096] Specifically, when any hard disk identification module identifies that the hard disk label at the pasting position is of a preset type, the types and quantities of all hard disks are determined according to the number of conductive loops, and the types and quantities of all hard disks are transmitted to the corresponding signal conversion module.

[0097] Specifically, the disk array card identification module includes: a third power supply, a loop switch, a third resistor, a fourth power supply, and a second AND gate logic unit. The loop switch connects the third power supply and one end of the third resistor; the other end of the third resistor is connected to the first input end of the second AND gate logic unit; the second input end of the second AND gate logic unit is connected to the fourth power supply. The third input end of the second AND gate logic unit is electrically connected to the second output end of the decision module, and is used to receive a state switching signal of the decision module. The output end of the second AND gate logic unit is electrically connected to the input end of the decision module of another cable installation position identification 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 types and quantities of all hard disks into level signals, and transmits the level signals 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 identification 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 identification module and the level signal 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 of hard disk is installed in a hard disk tray, a preset type of hard disk label will be affixed to the corresponding hard disk tray, wherein the preset type of hard disk indicates a hard disk that requires the cooperation of a disk array card. After the preset type of hard disk label is affixed, if the number of preset type hard disks requires a disk array card, the disk array card identification module is set between the two cable installation position identification devices, and the disk array card identification module receives the state switching signal output by the second output end of the first cable installation position identification device, and sends it to the decision module of the second cable installation position identification device after processing by the second AND gate logic unit, so that the NOR gate logic unit of the second cable installation position identification device processes all level signals and the installation status signal of the disk array card identification module, and outputs a control signal for controlling the second indication module.

[0103] In summary, the disk array card identification module is installed on a normal disk array card bracket and is only used to identify whether the disk array card is installed, and does not affect the original physical structure and function. When the hard disk identification module identifies the preset type of hard disk, the disk array card needs to cooperate with the hard disk. The disk array card identification module provided in this embodiment can identify the cable installation position together with the preset type of hard disk after the disk array card is installed, eliminating the need to check the code of each cable one by one during production line operation, and then check the assembly manual for the installation position corresponding to this code before assembly. It can greatly save the cable installation time in the production process.
