The electronic board, information processing device, and cable connection support method according to an embodiment of the present invention will be described in detail below with reference to the drawings.

<Electronic substrate>
Fig. 1 is a block diagram showing the main configuration of an electronic board according to an embodiment of the present invention. As shown in Fig. 1, a main board 10 as an electronic board of this embodiment includes a connector 11, an LED (Light Emitting Diode) 12 (light emitting element), a 7-segment display 13 (display element), a controller 14 (first controller), a dedicated connector 15, a switch 16 (indicator), and a button battery 17 (power supply element).

The connector 11 is a component to which one end of a cable that connects the main board 10 to another electronic board (for example, the sub-board 20 shown in FIG. 2) is attached. A plurality of connectors 11 are provided on the main board 10. In the example shown in FIG. 1, four connectors 11 (connectors 11a to 11d) are provided. The shapes of the connectors 11 may be the same or different.

A plurality of LEDs 12 are provided corresponding to each of the connectors 11. In the example shown in FIG. 1, four LEDs 12 (LEDs 12a to 12d) are provided corresponding to the four connectors 11 (connectors 11a to 11d). The LEDs 12 are turned on or off under the control of the controller 14. The LEDs 12 are provided to identify the connector to which one end of a cable should be attached when connecting the main board 10 to another electronic board with a cable. For example, the connector to which one end of the cable should be attached is identified by turning on only one of the plurality of LEDs 12 under the control of the controller 14.

The seven-segment display 13 displays various information under the control of the controller 14. For example, the seven-segment display 13 displays information identifying the cable connecting the main board 10 to other electronic boards (for example, a cable management number or cable model number, described below). Note that while FIG. 2 illustrates a two-digit seven-segment display 13, the seven-segment display 13 may be a one-digit display, or a three-digit display or more.

The controller 14 runs on power supplied from a button battery 17, and controls the display content of the seven-segment display 13, and the turning on and off of the LED 12. The controller 14 also collects information about other electronic boards via a dedicated connector 15, and controls the turning on and off of LEDs (e.g., LED 22 of the sub-board 20 shown in FIG. 2) provided on the other electronic boards. In other words, the controller 14 controls the seven-segment display 13 to display information identifying a cable connecting the main board 10 to the other electronic boards. The controller 14 also controls to identify the connector on the main board 10 to which one end of the cable is attached, and the connector on the other electronic board to which the other end of the cable is attached.

The controller 14 controls the turning on and off of the LEDs on the other electronic boards by outputting information specifying the LEDs on the other electronic boards to a controller of the other electronic board (for example, the controller 23 shown in FIG. 2) via a dedicated connector 15. The turning on and off of the LEDs on the other electronic boards is controlled by the controller on the other electronic boards based on information output from the controller 14 on the main board 10 via the dedicated connector 15.

The controller 14 controls the display contents of the seven-segment display 13 and the turning on and off of the LEDs 12 based on the cable management table TB1, controller management table TB2, and work management table TB3 (management tables). The cable management table TB1 is a table that manages the cables that connect the main board 10 to other electronic boards. The controller management table TB2 is a table that manages the controllers provided on other electronic boards connected to the main board 10. The work management table TB3 is a table that manages the contents to be displayed on the seven-segment display 13 and the LEDs to be turned on when the work of connecting the main board 10 to other electronic boards with cables is performed. The cable management table TB1, controller management table TB2, and work management table TB3 will be described in detail later.

The dedicated connector 15 is a connector to which one end of a dedicated cable that connects the controller 14 provided on the main board 10 to a controller provided on another electronic board is attached. The controller 14 provided on the main board 10 can communicate with the controller provided on the other electronic board via the dedicated cable attached to the dedicated connector 15.

The switch 16 is an element that is turned on (conducting) or off (open) depending on, for example, the operator's operation. This switch 16 is used to instruct the controller 14 to change the display content of the seven-segment display 13 and the LEDs to be lit (the LEDs 12 on the main board 10 and the LEDs provided on other electronic boards). For example, when the switch 16 changes from an off state to an on state, an instruction to change the display content of the seven-segment display 13 and the LEDs to be lit is given.

The button battery 17 supplies the controller 14 with the power necessary for the controller 14 to operate. In addition, when a controller provided on another electronic board is connected by a dedicated cable attached to the dedicated connector 15, the button battery 17 supplies the power necessary for that controller to operate.

Although not shown, the main board 10 is provided with a signal processing circuit in addition to the controller 14. This signal processing circuit processes signals sent to and received from other electronic boards connected by cables attached to the connector 11. The controller 14 operates independently of the signal processing circuit provided on the main board 10.

Cable Management Table
Table 1 below shows an example of a table management table used by the controller 14. As shown in Table 1, cable management table TB1 is a table in which cable management numbers, cable model numbers, connector information, and other information are associated with each other. The cable management number is a unique number assigned to each cable. The cable model number is information indicating the model number of the cable. The connector information is information indicating the shape and number of pins of the connectors provided on both ends of the cable. The other information is information indicating the characteristics or uses of the cable. It is necessary for cable management table TB1 to have, at a minimum, the area surrounded by a thick line.

<Controller Management Table>
Table 2 below is an example of a controller management table TB2 used by the controller 14. As shown in Table 2, the controller management table TB2 is a table in which controller numbers, mounted boards, LED management numbers, connector information, signal types, and other information are associated with each other. The controller number is a unique number assigned to each controller. The mounted board is information indicating the board on which the controller is mounted. The LED management number is information indicating the LEDs managed by the controller mounted on each board. The connector information is information indicating the shape and number of pins of the connector to which one end or the other end of the cable is connected. The other information is information indicating the characteristics or use of the cable. It is necessary for the controller management table TB2 to have at least the area surrounded by the thick line.

<Work Management Table>
Table 3 below shows an example of a work management table TB3 used by the controller 14. As shown in Table 3, the work management table TB3 is a table in which connection work steps, cable management numbers, connection source information, connection destination information, and other information are associated with each other. The connection work steps are information indicating the order of work when connecting the main board 10 to another electronic board with a cable. The cable management numbers are unique numbers assigned to each cable and are the same as the cable management numbers shown in Table 1.

The connection source information is information that specifies the connector to which one end of the cable is connected. This connection source information includes information that indicates the board on which the connector is mounted, and information that indicates the LED provided in correspondence with that connector. The connection destination information is information that specifies the connector to which the other end of the cable is connected. This connection destination information includes information that indicates the board on which the connector is mounted, and information that indicates the LED provided in correspondence with that connector. Other information is information that indicates the characteristics or use of the cable. Note that the work management table TB3 only needs to have, at a minimum, the area surrounded by a thick line.

Figure 2 is a block diagram showing the main configuration of another electronic board to which an electronic board according to one embodiment of the present invention is connected. As shown in Figure 2, a sub-board 20 as another electronic board includes a connector 21, an LED 22 (light-emitting element), a controller 23 (second controller), and a dedicated connector 24.

The connector 21 is a component to which the other end of the cable that connects the sub-board 20 and the main board 10 shown in FIG. 1 is attached. A plurality of connectors 21 are provided on the sub-board 20. In the example shown in FIG. 2, two connectors 21 (connectors 21a and 21b) are provided. The shapes of the connectors 21 may be the same or different.

A plurality of LEDs 22 are provided corresponding to each of the connectors 21. In the example shown in FIG. 2, two LEDs 22 (LEDs 22a, 22b) are provided corresponding to the two connectors 21 (connectors 21a, 21b). The LEDs 22 are turned on or off under the control of the controller 23. The LEDs 22 are provided to identify the connector to which the other end of the cable should be attached when connecting the sub-board 20 and the main board 10 with a cable. For example, the connector to which the other end of the cable should be attached is identified by turning on only one of the plurality of LEDs 22 under the control of the controller 23.

The controller 23 operates using power supplied via the dedicated connector 24, and controls the turning on and off of the LED 22 based on information input via the dedicated connector 24. The power supplied via the dedicated connector 24 is power supplied from the button battery 17 shown in FIG. 1. The information input via the dedicated connector 24 is information that identifies the LED 22 on the sub-board 20, output from the controller 14 shown in FIG. 1.

In addition, when an information collection request is sent via the dedicated connector 24, the controller 23 outputs information about the sub-board 20 to the dedicated connector 24. For example, the controller 23 outputs information indicating the connectors mounted on the sub-board 20 (connector information in Table 2) and information indicating the LEDs mounted on the sub-board 20 (LED control numbers in Table 2) to the dedicated connector 24.

The dedicated connector 24 is a connector to which the other end of the dedicated cable that connects the controller 23 provided on the sub-board 20 and the controller 14 provided on the main board 10 is attached. The controller 23 provided on the sub-board 20 can communicate with the controller 23 provided on the main board 10 via the dedicated cable attached to the dedicated connector 24.

Although not shown in the figure, the sub-board 20 also has a signal processing circuit in addition to the controller 23. This signal processing circuit processes signals sent to and received from the main board 10, which is connected by a cable attached to the connector 21. The controller 23 operates independently of the signal processing circuit provided on the sub-board 20.

Information Processing Device
Fig. 3 is a block diagram showing the main configuration of an information processing device according to an embodiment of the present invention. As shown in Fig. 3, the information processing device 1 of this embodiment includes a main board 10 (first electronic board) and multiple sub-boards 20 (second electronic boards). The information processing device 1 illustrated in Fig. 3 includes one main board 10 and five sub-boards 20 (sub-boards 20a to 20e).

The main board 10 has the same configuration as that shown in FIG. 1, and the sub-board 20 has the same configuration as that shown in FIG. 2. The type of connector 21 provided on the sub-board 20 may be the same as that shown in FIG. 2 or may be different. The number of connectors 21 and LEDs 22 provided on the sub-board 20 may be the same as that shown in FIG. 2 or may be different.

The controller 14 provided on the main board 10 operates as a master. The controller 23 provided on the sub-board 20 (sub-boards 20a to 20e) controls the turning on and off of the LEDs 22 provided on the sub-board 20 (sub-boards 20a to 20e) under the instruction of the controller 14 provided on the main board 10.

In the information processing device 1 of this embodiment, the connector 11 provided on the main board 10 and the connector 21 provided on the sub-board 20 are connected by a cable (for example, the cable CB1 shown in FIG. 3). Note that FIG. 3 illustrates an example in which the dedicated connector 15 provided on the main board 10 and the dedicated connector 24 provided on the sub-board 20 are connected by a dedicated cable CB0. This connection is made before the work of connecting the connector 11 provided on the main board 10 and the connector 21 provided on the sub-board 20 by a cable (not shown) is performed. Note that the dedicated cable CB0 may be removed after the work of connecting the connector 11 provided on the main board 10 and the connector 21 provided on the sub-board 20 is completed.

<Cable connection support method>
Fig. 4 is a flowchart showing a cable connection assistance method according to an embodiment of the present invention. In the flowchart shown in Fig. 4, for ease of understanding, steps performed by an operator and processes performed by the controller 14 and the like are mixed.

[Step S11]
The worker performs the task of defining the cable management table TB1 to be used in the information processing device 1. Specifically, the worker performs the task of defining the cable management table TB1 (see Table 1) in which cable management numbers, cable model numbers, connector information, and other information are associated with each other for all of the cables to be used in the information processing device 1. The defined cable management table TB1 is stored in the controller 14 of the main board 10.

[Step S12]
The worker performs the task of defining a controller management table TB2 to be used in the information processing device 1. Specifically, the worker performs the task of defining a controller management table TB2 (see Table 2) in which controller numbers, mounted boards, LED management numbers, connector information, signal types, and other information are associated with each other for all boards (main board 10 and sub-board 20) provided in the information processing device 1. The defined controller management table TB2 is stored in the controller for each board separately. For example, the controller management table TB2 for the main board 10 is stored in the controller 14 of the main board 10, and the controller management table TB2 for the sub-board 20a is stored in the controller 23 of the sub-board 20a.

[Step S13]
The worker performs the task of defining a work management table TB3 to be used in the information processing device 1. Specifically, the worker performs the task of defining a work management table TB3 (see Table 3) in which cable management numbers, connection source information, connection destination information, and other information are associated with the order in which the cables are connected (the order of connection work steps) in the information processing device 1. The defined work management table TB3 is stored in the controller 14 of the main board 10. The tasks shown in steps S11 to S13 do not necessarily have to be performed in this order. For example, the tasks shown in steps S11 to S13 may be performed simultaneously.

[Step S14]
The worker connects the dedicated connector 15 provided on the main board 10 constituting the information processing device 1 to the dedicated connector 24 provided on each of the sub-boards 20 with a dedicated cable CB0. By performing this operation, the controller 14 provided on the main board 10 and the controller 23 provided on the sub-board 20 are connected with each other via the dedicated cable CB0 (see FIG. 3).

[Step S15]
The controller 14 provided on the main board 10 acquires information from the controllers 23 provided on each of the sub-boards 20, and performs processing to consolidate the acquired information to create a controller management table TB2 shown in Table 3. Then, the controller 14 provided on the main board 10 causes the seven-segment display 13 to display the letter "S," which means the start of the cable connection work, based on the information (Start) stored at the top of the work management table TB3 (step S15).

[Step S16]
The operator knows that the cable connection work is ready by referring to the letter "S" displayed on the seven-segment display 13. When the operator presses the switch 16 provided on the main board 10, the cable connection work is started. When the cable connection work is started, the controller 14 provided on the main board 10 reads out the cable management number, the connection source information, and the connection destination information corresponding to the connection work step "1" from the work management table TB3. Then, the controller 14 controls the display content of the seven-segment display 13 and controls the lighting of the LED 12 based on the read information. Specifically, the controller 14 displays the read cable management number on the seven-segment display 13 (first step). Furthermore, the controller 14 lights up the LED provided corresponding to the connector to which the cable is to be connected based on the read connection source information and connection destination information (second step).

For example, the controller 14 displays "2" as the cable model number on the seven-segment display 13. Also, assume that the information indicating the board included in the connection source information indicates the main board 10, and the LED management number included in the connection source information identifies LED 12a. Then, the controller 14 lights up the LED 12a provided on the main board 10. Also, assume that the information indicating the board included in the connection destination information indicates the sub-board 20a, and the LED management number included in the connection destination information identifies LED 22a. Then, the controller 14 outputs information identifying LED 22a of the sub-board 20a to the controller 23 of the sub-board 20a via the dedicated connector 15. The controller 23 of the sub-board 20a lights up LED 22a of the sub-board 20a based on the information output from the controller 14.

[Step S17]
The worker selects a cable according to the cable number displayed on the seven-segment display 13 .

[Step S18]
The worker connects the selected cable to the connector with the LED nearby that is lit. For example, assume that the seven-segment display 13 displays "2" and the LED 12a on the main board 10 and the LED 22a on the sub-board 20a are lit. The worker then selects the cable identified by the cable number "2" and connects the selected cable to the connector 11a on the main board 10 and the connector 21a on the sub-board 20a.

[Step S19]
When the above work is completed and the worker presses the switch 16, the next cable connection work is started. That is, the controller 14 provided on the main board 10 reads out the cable management number, the connection source information, and the connection destination information corresponding to the connection work step "2" from the work management table TB3. Then, the controller 14 controls the display content of the seven-segment display 13 and controls the lighting of the LED 12 based on the read information (step S16). Specifically, the controller 14 causes the seven-segment display 13 to display the read cable management number (first step). Also, the controller 14 turns on the LED provided corresponding to the connector to which the cable is to be connected based on the read connection source information and connection destination information (second step).

The worker selects a cable according to the cable number displayed on the seven-segment display 13 (step S17). The worker then connects the selected cable to the nearby connector whose LED is lit (step S18). When the worker completes the above steps and presses the switch 16, the next cable connection work begins. Thereafter, each time the worker presses the switch 16, the display content of the seven-segment display 13 and the lit LEDs 12 are switched, and the selected cables are connected in sequence.

Then, when the information (End) stored at the end of the work management table TB3 is read, the controller 14 causes the seven-segment display 13 to display the letter "E," which means that the cable connection work is complete, based on that information. When the letter "E" appears on the seven-segment display 13, the worker knows that the cable connection work is complete. This completes the cable connection work.

When the worker presses switch 16 after completing the cable connection work, the letter "S", indicating the start of the cable connection work, is again displayed on the seven-segment display 13 based on the information (Start) stored at the top of the work management table TB3. Then, each time switch 16 is pressed, the display content of the seven-segment display 13 and the lit LED 12 are switched according to the contents of the work management table TB3. This makes it possible to check and verify the cable connection after the cable connection work is completed.

Figure 5 is a block diagram showing another example configuration of an information processing device according to an embodiment of the present invention. The information processing device 2 shown in Figure 5 has a different internal board configuration from the information processing device 1 shown in Figure 3. Specifically, the information processing device 1 shown in Figure 3 is configured with one main board 10 and five sub-boards 20 (sub-boards 20a to 20e). In contrast, the information processing device 2 shown in Figure 5 is configured with one main board 10 and four sub-boards 20 (sub-boards 20f to 20i).

In this way, if the internal board configuration is different, the cable management table TB1, controller management table TB2, and work management table TB3 can be redefined to match the board configuration. For example, in the information processing device 2 shown in FIG. 5, the work management table TB3 shown in Table 4 below can be used instead of the work management table TB3 shown in Table 3. In this way, by changing the definition of the work management table TB3, it is possible to accommodate information processing devices with different board configurations.

As described above, in this embodiment, information indicating the cable used to connect the main board 10 and the sub-board 20 is displayed on the seven-segment display 13. In addition, the LED 12 provided corresponding to the connector 11 of the main board 10 to which the cable is connected is illuminated, and the LED 22 provided corresponding to the connector 21 of the sub-board 20 to which the cable is connected is illuminated. This makes it possible to prevent mistakes in cable selection and in identifying the connection location, regardless of the worker's level of skill. As a result, the device can be assembled in a short time.

<Minimum configuration example>
6 is a diagram showing an example of a minimum configuration of an electronic board according to an embodiment of the present invention. As shown in FIG. 6, the electronic board 10 includes at least two connectors 11, two LEDs 12, a seven-segment display 13, and a controller 14. The connector 11 is a component to which one end of a cable that connects the main board 10 to another electronic board (e.g., the sub-board 20 shown in FIG. 2) is attached. The LEDs 12 are provided corresponding to each of the connectors 11. The seven-segment display 13 displays various information (e.g., a cable management number or a cable model number) under the control of the controller 14. The controller 14 controls the display content of the seven-segment display 13 and controls the turning on and off of the LEDs 12.

The above describes an electronic board, information processing device, and cable connection support method according to an embodiment of the present invention, but the present invention is not limited to the above embodiment and can be freely modified within the scope of the present invention. For example, the present invention can be applied whether assembling a new information processing device or adding options to an existing information processing device.
