　FIG. 1 is a diagram illustrating a configuration example of a wiring aggregation system 5 according to an embodiment of the present invention. The wiring aggregation system 5 includes wiring aggregation devices 1-1, 1-2, 1-3, and 1-4. The wiring aggregation devices 1-1 to 1-4 have the same configuration, and are referred to as the wiring aggregation device 1 unless otherwise distinguished.

The subunit 3 is connected one-to-one with one of the subunits 3 included in the other wiring aggregation device 1 via the inter-device cable 4.
[0011]
　In FIG. 1, the wiring aggregation device 1 includes three subunits 3, but is an example, and the number of subunits may be two or less or four or more. That is, the wiring aggregation device 1 includes one or more subunits 3. In the wiring aggregation system 5, contact information is transmitted and received between the subunits 3 included in the wiring aggregation device 1. The contact information is a signal transmitted / received between devices installed in the railway vehicle. Examples of the device include, but are not limited to, a driver's cab, a door, and an air conditioner. Since the contents of the device and the contact information assumed in the present embodiment are common in railway vehicles, detailed description thereof is omitted. The wiring aggregation device 1 is a device used to reduce the number of wirings between devices that transmit and receive contact information. Therefore, when the flow of contact information in one direction is viewed between devices that transmit and receive contact information, the wiring aggregation device 1 for aggregating contact information from a plurality of devices, and the aggregated contact information in the original Two of the wiring aggregation devices 1 for returning to the number are required. In the case of the flow of contact information in the reverse direction, the wiring aggregating device 1 for returning the above-mentioned aggregated contact information to the original number is now a device for aggregating a plurality of contact information, and the above-mentioned contact information is aggregated. In this case, the wiring aggregation device 1 is a device that returns the aggregated contact information to the original number.
[0012]
　FIG. 2 is a diagram illustrating an example in which the configuration of the wiring aggregation device 1 according to the present embodiment is expressed in module units. The wiring aggregation device 1 includes a power supply module 2 and subunits 3-1 to 3-3. Each subunit 3 includes a control module 10 and input / output modules 20-1 and 20-2. The input / output modules 20-1 and 20-2 have the same configuration and are referred to as the input / output module 20 unless otherwise distinguished. As described above, the wiring aggregation device 1 can include one or more subunits 3, but the subunit 3 can also include one or more input / output modules 20.

The input / output module 20 is connected to devices such as a driver's cab and a door (not shown) to input / output contact information. The number of devices that can be connected to the input / output module 20 depending on the model, that is, the maximum number of contact information that can be handled is determined. The input / output module 20 is connected to, for example, 16 devices, and inputs / outputs contact information between the connected devices. The number of devices to which the input / output module 20 can be connected is 16 as an example, and the present invention is not limited to this.
[0013]
　FIG. 3 is a block diagram illustrating a configuration example of the wiring aggregation device 1 according to the present embodiment. Here, only the subunit 3-1 is described in detail, and the description of the subunits 3-2 and 3-3 is simplified, but the subunits 3-2 and 3-3 are similar to the subunit 3-1. It is a configuration. As described above, the subunit 3-1 includes the control module 10 and the input / output modules 20-1 and 20-2. First, the configuration of the control module 10 will be described. The control module 10 includes an inter-module interface (hereinafter referred to as IF (InterFace)) unit 11, a frame generation unit 12, a wiring-side IF unit 13, a frame processing unit 14, and a control unit 15.
[0014]
　The inter-module IF unit 11 acquires a plurality of serial signals obtained by parallel-to-serial conversion of contact information from each of the input / output modules 20-1 and 20-2, and outputs the serial signals to the frame generation unit 12. A serial signal output from the input / output modules 20-1 and 20-2 to the inter-module IF unit 11, that is, the control module 10, is defined as a first serial signal. Further, the inter-module IF unit 11 extracts a plurality of serial signals, which are extracted from the received frame from the other wiring aggregation device 1 from the frame processing unit 14 and whose contact information is parallel-serial converted by the other wiring aggregation device 1. It is acquired and output to each of the corresponding input / output modules 20-1 and 20-2. A serial signal output from the inter-module IF unit 11, that is, the control module 10 to the input / output modules 20-1 and 20-2 is defined as a second serial signal.
[0015]
　The frame generation unit 12 arranges each of the first serial signals acquired from the input / output modules 20-1 and 20-2 at the frame position defined by each input / output module 20, and sends it to the other wiring aggregation device 1. A transmission frame for transmission is generated.
[0016]
　FIG. 4 is a diagram illustrating an example of a frame format of a transmission frame generated by the frame generation unit 12 of the control module 10 according to the present embodiment. Here, as an example, the maximum number of devices 6 that can be connected by the input / output modules 20-1 and 20-2 is assumed to be 16. The frame generation unit 12 obtains the first serial signal acquired from the input / output module 20-1, that is, the contact information of 16 devices 6 from “20-10” to “20” in order from the left side of the frame format shown in FIG. 20-1 15 ”frame position. The frame generation unit 12 also obtains the first serial signal acquired from the input / output module 20-2, that is, the contact information of the device 6 for 16 pieces, and the right of the frame position where the contact information of the input / output module 20-1 is arranged. The frames are arranged at adjacent frame positions “20-20” to “20-2 15”. The size of the specified frame position is a size at which the maximum number of contact information that can be handled by the input / output module 20 that is the output source of the first serial signal arranged at the frame position can be arranged. When there is one input / output module 20 connected to the control module 10, the number of first serial signals included in the transmission frame is one from one input / output module 20.
[0017]
　Here, when the input / output module 20 can be connected to a maximum of 16 devices 6 but is actually connected to only 8 devices 6, as described later, the empty portion of the contact information is left as it is. The first serial signal is generated using 16 spaces. Thereby, in the frame format shown in FIG. 4, the contact information of the specific device 6 of the specific input / output module 20 is arranged at a specific position. A specific position corresponds to a specific port of the input / output module 20 to which the device 6 is connected. Further, as described above, the subunit 3 can include a plurality of input / output modules 20. For example, as shown in FIG. 2, the input / output module 20-1, the input / output module 20-2,... The arrangement order of the output modules 20 can be uniquely determined. As described above, in the frame format, the arrangement order of the input / output modules 20 and the arrangement order of the contact information in the first serial signal are set in advance.
[0018]
　The control module 10 of the other wiring aggregation device 1 that has received the frame of the frame format shown in FIG. It is possible to grasp which information is contact information corresponding to which device 6 of which input / output module 20. In the example of FIG. 4, it is assumed that there are two input / output modules 20, but the same frame format can be used even if there are three or more input / output modules 20. For example, if there are three input / output modules 20, “20-30” to “20-3 15” may be added to the right side of “20-2 15” in the frame format shown in FIG.
[0019]
　Returning to the description of the control module 10. The wiring-side IF unit 13 transmits the transmission frame generated by the frame generation unit 12 to the other wiring aggregation device 1 to be connected. Specifically, the wiring side IF unit 13 transmits a transmission frame to the wiring side IF unit 13 of the control module 10 included in the connected subunit 3 among the other wiring aggregation devices 1. In addition, when receiving a frame from another wiring aggregation device 1, the wiring side IF unit 13 outputs the received frame to the frame processing unit 14. Note that the frame format of the frame received by the wiring side IF unit 13 from the other wiring aggregation device 1, that is, the received frame is the frame format shown in FIG.
[0020]
　The frame processing unit 14 extracts a plurality of second serial signals arranged at the frame position defined by each input / output module 20 from the reception frame acquired from the wiring side IF unit 13. Specifically, when the frame processing unit 14 obtains a received frame in the frame format shown in FIG. 4, the second serial signal including 16 pieces of contact information from the left is extracted for the input / output module 20-1. Further, the frame processing unit 14 extracts the second serial signal composed of the contact information for 16 pieces of the right adjacent to the second serial signal for the input / output module 20-1 for the input / output module 20-2. The frame processing unit 14 outputs the extracted second serial signal for the input / output module 20-1 and the extracted second serial signal for the input / output module 20-2 to the inter-module IF unit 11. When the number of input / output modules 20 connected to the control module 10 is one, the number of second serial signals included in the received frame is one.
[0021]
　The control unit 15 controls transmission / reception of a frame, that is, contact information with another wiring aggregation device 1. Specifically, when the subunit 3 including the control module 10 is activated, the control unit 15 confirms the number of input / output modules 20 connected to the control module 10 including itself. The control unit 15 requests information on the number of input / output modules 20 to be connected to the control module 10 of another wiring aggregation device 1 connected to the control module 10 including itself, and Information on the number of input / output modules 20 to be connected is acquired from the control module 10. The control unit 15 compares the number of input / output modules 20 connected to the control module 10 including itself with the number of input / output modules 20 connected to the control module 10 of another wiring aggregation device 1. When the number of input / output modules 20 is the same, the control unit 15 performs control to transmit / receive a frame including contact information to / from another wiring aggregation device 1. When the number of input / output modules 20 is different, the control unit 15 does not transmit / receive a frame including contact information to / from another wiring aggregation device 1.
[0022]
　Next, the configuration of the input / output module 20 will be described. Since the input / output modules 20-1 and 20-2 have the same configuration as described above, the input / output module 20-1 will be described as an example. The input / output module 20-1 includes an input unit 21, a parallel serial (hereinafter referred to as PS (Parallel Serial)) conversion unit 22, an inter-module IF unit 23, and a serial parallel (hereinafter referred to as SP (Serial Parallel)). ) A conversion unit 24 and an output unit 25 are provided.
[0023]
　The input unit 21 collects contact information from the plurality of devices 6 and outputs the collected contact information to the PS conversion unit 22. The maximum number of devices 6 that can collect contact information at the input unit 21 is the maximum number of devices 6 that can be connected in the input / output module 20.
[0024]
　The PS converter 22 converts the contact information acquired from the input unit 21 from a parallel signal to a serial signal, that is, performs parallel-serial conversion to generate a first serial signal. Here, when the number of devices 6 connected to the input / output module 20 is less than the maximum number that can be connected, for example, the PS conversion unit 22 is 16 spaces including empty portions of contact information. Is used to generate the first serial signal. As described above, in the frame format shown in FIG. 4, the contact information of the specific device 6 of the specific input / output module 20 is arranged at a specific position. For example, when the input unit 21 can acquire contact information from the device 6 connected to the ports # 0 to # 15, but the device 6 is not connected to the ports # 4 to # 11, the PS conversion unit 22 The first serial signal is generated without changing the arrangement for each port, leaving a space for contact information for ports # 4 to # 11. The PS conversion unit 22 outputs the generated first serial signal to the inter-module IF unit 23.
[0025]
　When the inter-module IF unit 23 acquires the first serial signal from the PS conversion unit 22, the inter-module IF unit 23 outputs the first serial signal to the control module 10. Further, when the inter-module IF unit 23 acquires the second serial signal from the control module 10, the inter-module IF unit 23 outputs the second serial signal to the SP conversion unit 24.
[0026]
　The SP conversion unit 24 converts the second serial signal acquired from the inter-module IF unit 23 into a parallel signal, that is, serial-parallel conversion. Here, the SP conversion unit 24 acquires a second serial signal having a size corresponding to 16 pieces of contact information of the left half or the right half of the reception signals in the frame format shown in FIG. The SP converter 24 converts the second serial signal having a size corresponding to 16 pieces of contact information into a parallel signal. The SP conversion unit 24 outputs a parallel signal of contact information obtained as a result of the serial / parallel conversion to the output unit 25.
[0027]
　The output unit 25 outputs a parallel signal of contact information acquired from the SP conversion unit 24, that is, each of a plurality of contact information, to each of a plurality of corresponding devices 6. As shown in FIG. 3, the contact information collecting device 6 collected by the input unit 21 and the contact information output destination device 6 outputted by the output unit 25 are the same. The input / output module 20 exchanges contact information with each device 6, that is, collects and outputs contact information.
[0028]
　Next, the operation of the wiring aggregation device 1 will be described. First, an operation for determining whether or not the wiring aggregation device 1 can transmit / receive a frame including contact information to / from another wiring aggregation device 1 will be described. FIG. 5 is a flowchart showing an operation of determining whether or not the wiring aggregation device 1 according to the present embodiment can transmit / receive a frame including contact information to / from another wiring aggregation device 1.
[0029]
　First, in the control module 10, when the subunit 3 including the control module 10 is activated, the control unit 15 confirms the number of input / output modules 20 connected to the control module 10 of the own device (step S1). For example, the control unit 15 checks the number of input / output modules 20 to be connected via the inter-module IF unit 11. The control unit 15 acquires information on the number of input / output modules 20 connected to the control module 10 of the other wiring aggregation device 1 from the control module 10 of the other wiring aggregation device 1 (step S2). For example, the control unit 15 acquires information on the number of input / output modules 20 from the control module 10 of the other wiring aggregation device 1 via the wiring side IF unit 13.
[0030]
　The control unit 15 compares the number of input / output modules 20 connected to the control module 10 of its own device with the number of input / output modules 20 connected to the control module 10 of another wiring aggregation device 1 (step S3). When the number of input / output modules 20 is the same (step S3: Yes), the control unit 15 performs control to transmit / receive a frame including contact information to / from another wiring aggregation device 1 (step S4). An operation in which the wiring aggregation device 1 transmits and receives a frame including contact information with another wiring aggregation device 1 will be described using a separate flowchart. When the number of the input / output modules 20 is different (step S3: No), the control unit 15 does not transmit / receive a frame to / from another wiring aggregation device 1 (step S5).
[0031]
　For example, in step S2, when the frame including contact information is transmitted / received between the two wiring aggregation apparatuses 1, the wiring aggregation apparatus 1 transmits the frame first. The wiring aggregation device 1 that has requested information on the number of input / output modules 20 from the aggregation device 1 transmits the frame first. However, the method of determining the frame transmission order of the wiring aggregation device 1 is not limited to this method.
[0032]
　Next, an operation in which the wiring aggregation device 1 transmits the contact information collected by the own device to another wiring aggregation device 1 will be described. FIG. 6 is a flowchart illustrating an operation in which the wiring aggregation device 1 according to the present exemplary embodiment transmits a frame including contact information to another wiring aggregation device 1.
[0033]
　First, in each input / output module 20, the input unit 21 collects contact information from the connected device 6 (step S11). The input unit 21 outputs the collected contact information to the PS conversion unit 22. The PS conversion unit 22 converts the plurality of contact information acquired by the input unit 21 from a parallel signal to a serial signal, that is, parallel-serial conversion (step S12). The PS conversion unit 22 outputs the first serial signal generated by the parallel serial conversion to the inter-module IF unit 23. The inter-module IF unit 23 outputs the acquired first serial signal to the control module 10 (step S13).
[0034]
　In the control module 10, the inter-module IF unit 11 acquires the first serial signal from each input / output module 20 (step S14). The inter-module IF unit 11 outputs the acquired first serial signal to the frame generation unit 12. The frame generation unit 12 generates a transmission frame having the frame format shown in FIG. 4 using the first serial signal acquired from the inter-module IF unit 11 (step S15). The frame generation unit 12 outputs the generated transmission frame to the wiring side IF unit 13. The wiring-side IF unit 13 transmits the acquired transmission frame to another wiring aggregation device 1 (step S16).
[0035]
　Next, an operation in which the wiring aggregation device 1 receives contact information from another wiring aggregation device 1 will be described. FIG. 7 is a flowchart illustrating an operation in which the wiring aggregation device 1 according to the present exemplary embodiment receives a frame including contact information from another wiring aggregation device 1.
[0036]
　First, in the control module 10, the wiring-side IF unit 13 receives a frame including contact information transmitted from another wiring aggregation device 1 (step S21). The wiring side IF unit 13 outputs the received frame to the frame processing unit 14. The frame processing unit 14 extracts the second serial signal arranged at the specified frame position from the received frame (step S22). The frame processing unit 14 outputs the extracted second serial signal to the inter-module IF unit 11. The inter-module IF unit 11 outputs the second serial signal acquired from the frame processing unit 14 to the corresponding input / output module 20 (step S23).
[0037]
　In the input / output module 20, the inter-module IF unit 23 acquires the second serial signal from the control module 10 (step S24). The inter-module IF unit 23 outputs the acquired second serial signal to the SP conversion unit 24. The SP conversion unit 24 converts the second serial signal acquired from the inter-module IF unit 23 into a parallel signal, that is, serial-parallel conversion (step S25). The SP conversion unit 24 outputs the parallel signal generated by the serial / parallel conversion to the output unit 25. The output unit 25 outputs the parallel signal of the contact information acquired from the SP conversion unit 24, that is, each of the plurality of contact information, to each of the corresponding plurality of devices 6 (step S26).
[0038]
　Thus, in the wiring aggregation system 5, in the plurality of wiring aggregation devices 1, the subunit 3 included in the wiring aggregation device 1 is connected to one of the subunits 3 included in the other wiring aggregation devices 1 in a one-to-one relationship. A plurality of contact information is converted from a parallel signal to a serial signal and transmitted. Thereby, in the railway vehicle equipped with the wiring aggregation device 1, the number of wires for transmission of contact information can be reduced as compared with a case where wiring is required for each contact information. Further, in the wiring aggregation system 5, even in the case where the contact information transmitted by adding the equipment 6 mounted on the railway vehicle is increased, or when the system in the railway vehicle is changed, the sub-unit 3 By increasing the number of input / output modules 20, it is possible to respond, that is, contact information can be transmitted and received without increasing the number of wires and without setting an address or the like. Specifically, the wiring aggregation device 1 can cope with an increase in contact information handled in a range that can be handled by the number of input / output modules 20 that can be added in the subunit 3, without increasing the number of wires, that is, the inter-device cables 4. . Further, in the wiring aggregation system 5, by using the wiring aggregation device 1, wiring work is facilitated as compared with the case where one wiring is prepared for one piece of contact information.
[0039]
　In the wiring aggregation device 1, when transmitting a frame to another wiring aggregation device 1, the frame generation unit 12 may rewrite and transmit the contact information of the set frame position in the first serial signal. Good. For example, the frame generation unit 12 rewrites the contact information of a specific door of a certain vehicle with the content of “open”. When a specific door of a certain vehicle opens as a result of a frame being transmitted from the wiring aggregation device 1 in which the contact information has been rewritten to another wiring aggregation device 1, the user goes from the wiring aggregation device 1 to a specific door of a certain vehicle. It can be easily confirmed that the connection is correct. As for the method of rewriting the contact information, the control module 10 may be set by the user by providing an operation unit (not shown in FIG. 3), or the user may be set by connecting a terminal to the control module 10. Good.
[0040]
　Further, the wiring aggregation device 1 may allow the frame processing unit 14 to check the contact information of the set frame position among the second serial signals included in the frame received from the other wiring aggregation device 1. . Thereby, the user can confirm the connection state from the device 6 connected to the other wiring aggregation device 1 to the wiring aggregation device 1 referred to by the user by referring to the confirmation result of the frame processing unit 14. The contents of the contact information of the wiring aggregation device 1 can be grasped. As for the method of referring to the confirmation result of the frame processing unit 14 by the user, the control module 10 may be provided with a display unit (not shown in FIG. 3) so that the user can refer to it, or by connecting a terminal to the control module 10. The user may be able to refer to it.
[0041]
　In the wiring aggregation system 5, both the subunits 3 of the wiring aggregation device 1 connected in a one-to-one manner perform the same operation, so that one wiring aggregation device 1 is a master and the other wiring aggregation device 1 is a slave. There is no need to set a relationship such as
[0042]
　In the example of FIG. 3, the inter-module IF unit 11 of the control module 10 and the inter-module IF unit 23 of each input / output module 20 are directly connected to the wiring aggregation device 1. However, the connection format with 20 is not limited to this. The connection format between the inter-module IF unit 11 of the control module 10 and the inter-module IF unit 23 of each input / output module 20 may be a ring network format.
[0043]
　In the wiring aggregation device 1, when a frame is transmitted from the control module 10, the frame generation unit 12 may add an error correction code to the end of the frame format of the transmission frame illustrated in FIG. 4. FIG. 8 is a diagram illustrating another example of the frame format of the transmission frame generated by the frame generation unit 12 of the control module 10 according to the present embodiment. The frame format shown in FIG. 8 is obtained by adding an error correction code to the footer position of the frame format shown in FIG. In another wiring aggregation device 1 that has received a frame to which an error correction code is added, the frame processing unit 14 can perform error detection using the error correction code. The frame processing unit 14 outputs the frame in which no error is detected to the input / output module 20 via the inter-module IF unit 11 as described above, discards the frame in which the error is detected, and does not output to the input / output module 20. . Thereby, the wiring aggregation apparatus 1 can improve the quality of the contact information transmitted / received.
[0044]
　Next, the hardware configuration of the wiring aggregation device 1 will be described. In the control module 10 included in the wiring aggregation device 1, the inter-module IF unit 11 and the wiring side IF unit 13 are interface circuits. The frame generation unit 12, the frame processing unit 14, and the control unit 15 are realized by a processing circuit. That is, the wiring aggregation device 1 includes a processing circuit for transmitting and receiving a frame arranged at a frame position where a serial signal of contact information is defined. The processing circuit may be a processor and a memory that execute a program stored in the memory, or may be dedicated hardware.
[0045]
　FIG. 9 is a diagram illustrating an example in which the processing circuit of the control module 10 included in the wiring aggregation device 1 according to the present embodiment is configured with a processor and a memory.
