Description

  The present invention relates to a combined state determination device for an automatic broadcasting device of a railway vehicle that detects a combined state in each vehicle formation for combined formations in which a plurality of vehicle formations are combined.

  In the field of in-car broadcasting, there is an automatic broadcasting system that automatically broadcasts a voice guidance such as the next stop station in the car according to the traveling position of the vehicle.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The configuration of the embodiment is an exemplification, and the present invention is not limited to the configuration of the embodiment.
<First Embodiment>
FIG. 1 is a diagram showing a configuration example of an automatic broadcast system to which an embodiment of the present invention can be applied. FIG. 2 is a diagram illustrating a configuration example of each automatic broadcast device illustrated in FIG. 1. FIG. 1 shows a combined knitting when the number N of vehicle knitting combined is 3 (N = 3, N is a positive integer), and an automatic broadcasting system related to the combined knitting.

  The combined formation includes a first vehicle formation T1, a second vehicle formation T2, and a third vehicle formation T3 in order from the top when the traveling direction is from the left to the right in FIG. Each of the vehicle formations T1 to T3 is formed by connecting three vehicles.

  The automatic broadcasting system shown in FIG. 1 is roughly configured as follows. That is, a plurality of lead-through lines are provided over all the vehicles constituting the combined knitting. In FIG. 1, voice lead-in lines L1 and L2 and a power amplifier (PA) starting lead-in line C are shown.

  A microphone 11 and a control amplifier 12 for the microphone are installed in each crew room of the first vehicle and the last vehicle of each vehicle organization, and the control amplifier 12 is connected to the lead-through lines L1, L2, and C, respectively. Each vehicle is provided with a power amplifier 13 for cabin broadcasting and a plurality of speakers 14 connected to the power amplifier 13. The power amplifier 13 is connected to the lead lines L1, L2, and C, respectively.

  Furthermore, automatic broadcasting apparatuses 15A, 15B, and 15C are mounted on each of the vehicle formations T1 to T3.

Each of the automatic broadcast devices 15A, 15B, and 15C is included in the memory (storage device) 21 in which broadcast pattern information is stored and the broadcast pattern information stored in the memory, like the automatic broadcast device 15 shown in FIG. Receiving position information from a playback device (including CODEC) 22 that demodulates and plays back sound information and a self-organized position detection device (detection unit 31) mounted in the vehicle composition, and corresponding sound information based on the position information And a control device (CPU or the like) 23 as control means for giving a playback instruction of the audio information to the playback device, and an interface circuit (
I / F) 24, 24 'are connected to the above-described lead lines L1, L2, C.

For example, in the automatic broadcast device 15A, the control device 23 receives the position information (running position) of the first vehicle formation T1, and if the position matches a predetermined broadcast timing, Is read from the memory 21 and given to the playback device 22. The playback device 22 performs audio information decompression processing and playback processing, and sends the audio signal to the lead-in lines L1 and L2 via the I / F 24. At this time, a control signal (voltage) for starting the power amplifier 13 of each vehicle is input (applied) to the lead-through line C, and each power amplifier 13 is started. The audio signal is input to the power amplifier 13 through the lead-through lines L1 and L2, amplified there, and then output to each speaker 14. Each speaker 14 can output the automatic broadcast sound from the automatic broadcast device 15A into the cabin.

  In addition, when audio broadcasting is performed from a certain crew cabin to each cabin in the first vehicle organization, the control amplifier 12 (microphone amplifier) is activated by the operation of the microphone 11 and power is supplied to the lead-through line C. A control signal (voltage) for activating the amplifier 13 is input (applied), and each power amplifier 13 is activated. In this state, when sound is input from the microphone 11, the sound is output from the control amplifier 12 to the lead-through lines L 1 and L 2 and input to each power amplifier 13. The sound amplified by the power amplifier 13 is output to each speaker 14. Each speaker 14 can output the cabin crew sound input from the microphone 11 into the cabin.

  The above-described automatic broadcast and the broadcast operation from the crew room can be performed through corresponding equipment in the second vehicle formation T2 and the third vehicle formation T3.

  Conventionally, in the combined knitting as shown in FIG. 1, only one of the automatic broadcast devices 15A, 15B, and 15C is turned on, and the remaining automatic broadcast devices are turned off. However, if each of the remaining automatic broadcast apparatuses carries out their own automatic broadcasts during the combined operation, more detailed broadcast guidance becomes possible. However, in order to carry out such automatic broadcasting, it is necessary for each vehicle organization to automatically recognize at least the position of the self-organization in the combined formation, and further, the number of vehicle formations constituting the combined formation. It is also desirable to automatically recognize the presence or absence of combined vehicle formation.

For this reason, the automatic broadcast system in 1st Embodiment is equipped with the following structures. That is, each of the automatic broadcast devices 15A, 15B, and 15C includes a detection unit 31 that is a detection unit for detecting the self-organization position as shown in FIG. A detection lead line LD is connected to the detection unit 31. The detection lead line LD is composed of at least N + 1 lead lines obtained by adding 1 to the number N of vehicle formations scheduled to be combined. In this embodiment, a detection comprising three detection lines (first detection line D1, second detection line D2, third detection line D3) and one ground line G according to the number of vehicles N = 3. A lead-through line LD is connected.

  Note that the number of lead-in lines constituting the lead-in line LD depends on the number N of vehicle formations. However, more than N + 1 lead lines may be prepared in advance, and only N + 1 lead lines may be used according to the number of vehicle formations N constituting the combined formation.

  The detection unit 31 includes photodiodes (FD) 32A, 32B, and 32C connected to the first detection line D1, the second detection line D2, and the third detection line D3, and ON / OFF of the FDs 32A, 32B, and 32C. And a detection circuit 33 for detecting an OFF state.

  FIG. 3A shows a detailed configuration of the lead-through line LD for detecting the self-organizing position. In each of the vehicle formations T1 to T3, detection lines D1 to D3 and a ground line G are arranged in a predetermined order. In the example shown in FIG. 3A, the detection line D1 is defined as the first (most significant), the detection line D2 is defined as the second, the detection line D3 is defined as the third, and the ground line G (grounding line) is 4th. (The lowest).

  The detection lines D1 to D3 and the ground line G are connected between the vehicle formations as follows. For example, the connection between the vehicle formation T1 and the vehicle formation T2 will be described as an example. The ground line G having the lowest (fourth) rank in the vehicle formation T1 is followed by the vehicle formation T2 via the connection line C4. Are connected to the detection line D1 having the highest (first) ranking.

  Further, each detection line D1 to D3 of the vehicle formation T1 is connected to a detection line or a ground line having a lower rank in the subsequent vehicle formation T2. That is, the detection line D1 of the vehicle formation T1 is connected to the detection line D2 of the vehicle formation T2 via the connection line C1, and the detection line D2 of the vehicle formation T1 is connected to the detection line D3 of the vehicle formation T2 via the connection line C2. The detection line D3 of the vehicle formation T1 is connected to the ground line G of the vehicle formation T3 via the connection line C3.

  A part including a plurality of connection lines C1 to C4 that connect the detection lines and ground lines (detection lead lines) between the vehicle formations constitutes the connection portion 41. Also between the vehicle formation T2 and the vehicle formation T3, detection lines and ground lines are connected by a plurality of connection lines C1 to C4 included in the connection portion 42 in accordance with the connection conditions as described above.

  The connection parts 41 and 42 described above are provided in one vehicle of the vehicle composition to be connected. However, the connection parts 41 and 42 may be provided in a connection part outside the vehicle between the vehicle formations.

  FIG. 3B shows a configuration example in which the detection line and the ground line are connected in one vehicle of the vehicle organization to be combined. In the example shown in FIG. 3B, the detection lines D1 to D3 and the ground line G of the connection portions 41A and 42A included in the vehicle formation T1 and the vehicle formation T2 are the following vehicles under the connection conditions applied to the connection portions 41 and 42 described above. The ground line G crosses the detection lines D1 to D3 so as to be connected to the knitting detection lines D1 to D3 and the ground line G, and the subsequent response is made through the connectors CN1 to CN4. Connected to the line to be played. By such connection between the vehicle formations, the detection line D1 (rank 1) is associated with the vehicle formation T1, the detection line D2 (rank 2) is associated with the vehicle formation T2, and the detection line D3. (Rank 3) is associated with vehicle formation T3.

  The above-described lead line LD, the detection unit 31 as the detection means in each of the automatic broadcast devices 15A to 15C, and the control device 23 as the control means constitute a combined state determination device for automatic broadcast devices.

  Next, the self-organizing position detection operation will be described. For example, the self-knitting position detecting operation is performed at a predetermined timing before the combined knitting departs from a predetermined traveling section. In a state where the vehicle formation is not combined, each of the detection lines D1 to D3 is in an open circuit state, and no current flows. On the other hand, when the detection lines D1 to D3 and the ground line G of each vehicle formation are connected by the connection lines C1 to C4 or the connectors CN1 to CN4 when the vehicle formations are combined, the detection lines connected to the ground line G are It will be in the state short-circuited and will be in the state into which an electric current flows.

For example, the detection line D3 of the vehicle formation T1 is short-circuited by being connected to the ground line G of the vehicle formation T2, and is in an energized state. Further, the detection line D2 of the vehicle formation T1 is short-circuited by being connected to the ground line G of the vehicle formation T3 via the detection line D3 of the vehicle formation T2, and becomes in an energized state. By supplying power to the FDs 32A, FD32B, and FD32C connected to the detection lead-out lines (detection lines D1 to D3) to which the ground line G is connected, the predetermined order (lowest) pass-through is performed. N lead-out lines (first to third detection lines D1) excluding the line (ground line G)
To D3) are detected.

  In the vehicle formation T1, as shown in FIG. 3, the detection line D1 is not connected to the ground line G over the entire vehicle formation. For this reason, the energized state is not established, and the corresponding FD 32A is turned off. On the other hand, since the detection line D2 and the detection line D3 are each connected to the ground line G, they are energized. Accordingly, the corresponding FDs 32B and 32C are turned on.

  In the vehicle formation T2, only the detection line D2 is not connected to the ground line G. Therefore, only the FD 32B corresponding to the vehicle formation T2 is turned off, and the FDs 32A and 32C are turned on.

  In the vehicle formation T3, only the detection line D3 is not connected to the ground line G. Therefore, only the FD 32C corresponding to the vehicle formation T3 is turned off, and the FDs 32A and 32B are turned on.

Therefore, when the three vehicle formations are combined, the detection line energization state in each vehicle formation (FD on / off
The off state is as shown in the table of FIG. 4A.

  FIG. 5 is a flowchart showing an operation example by the detection circuit 33 and the control device 23 in each vehicle composition. In step S1 of FIG. 5, the detection circuit 33 (FIG. 2) detects the on / off state from the FDs 32A, 32B, and 32C.

Next, in step S2, the detection circuit 33 generates a bit pattern (on / off pattern) corresponding to the on / off state. For example, the energization states of the first, second, and third detection lines D1, D2, and D3 in the first vehicle formation T1 are bit patterns “1 (OFF)”, “0 (O
N) "and" 0 (ON) ". The detection circuit 33 can generate such a bit pattern (on / off pattern) and notify the control device 23. The control device 23 can The position of the self-organization can be recognized by the on / off state of the detection line corresponding to itself in the on / off pattern.In the vehicle composition T1, the corresponding detection line D1 is “1 (off)”. Therefore, it can be recognized that the position of the self-organization is the head in the traveling direction.

Further, as shown in FIG. 4A, the on / off pattern in the vehicle formation T2 is “010”. Thereby, the control device 23 in the vehicle composition T2 can recognize that the own composition is located in the middle from the on / off pattern “010” (the corresponding detection line D2 is off (“1”)). Further, the on / off pattern in the vehicle formation T3 is “001”. As a result, the control device 23 in the vehicle formation T3 causes the on / off pattern “001” (
It can be recognized that the self-organization is located at the end from the corresponding detection line D3 off ("1").

  Next, in step S <b> 3, the control device 23 executes a control program stored in the memory 21 by a processor such as a CPU included in the control device 23, thereby obtaining a bit pattern (on / off pattern) obtained from the detection circuit 23. ) To determine the automatic broadcast pattern.

  For example, on the memory 21, in the combined composition, the first broadcast pattern information applied when the self-organization is the first (first) and the first broadcast pattern information applied when the self-organization is the second (intermediate). 2 broadcast pattern information and 3rd broadcast pattern information applied when self-organization is the tail (the 3rd) are stored beforehand.

  For example, the control device 23 performs determination using a table stored in advance on the memory 21 in which the on / off pattern and the broadcast pattern are associated with each other, and applies the broadcast pattern according to the on / off pattern. To decide.

  As a result, in the vehicle composition T1, it is determined that automatic broadcasting is performed with the first broadcast pattern corresponding to the on / off pattern “100”, and in the vehicle composition T2, the second broadcast corresponding to the on / off pattern “010” is determined. It is determined that automatic broadcasting is performed using a pattern, and in vehicle composition T3, it is determined that automatic broadcasting is performed using a third broadcast pattern corresponding to the on / off pattern “001”.

  Thereafter, in step S4, the control device 23 automatically performs setting for performing automatic broadcasting with the determined broadcast pattern.

  In addition, the position of each vehicle organization that constitutes the combined organization is determined according to each final destination (end point), and the first to third broadcast patterns correspond to the position of each own organization. Different audio information is included.

  Therefore, in the automatic broadcast system according to the embodiment, during the combined operation, the automatic broadcast apparatuses 15A, 15B, and 15C included in each of the first to third vehicle formations T1, T2, and T3 correspond to the position during the combined formation. It is possible to broadcast automatic broadcast sound based on a unique broadcast pattern.

However, as shown in FIG. 1, since the voice lead-in lines L1 and L2 (voice lines) are routed over the entire vehicle, the automatic broadcast apparatuses 15A, 15B and 15C are connected in parallel. When the automatic broadcast sound is output, the overlapping sound is broadcast. For this reason, the following operations can be considered.

  (Operation 1) The automatic broadcast device to be output is determined according to the combined state of the vehicle formations T1 to T3. For example, based on the combined state as shown in FIGS. 4A, 4B, and 4C, only the automatic broadcasting device 15A of the vehicle organization T1 performs automatic broadcasting, and other vehicle organization may not perform automatic broadcasting. it can. In this case, each automatic broadcast device 15B and 15C can be configured to be automatically turned off from the on / off pattern.

Alternatively, each automatic broadcast device 15 can be turned on / off manually. For example, an automatic broadcast device 15A, 15B, 15C changeover switch 50 (FIG. 6A) is provided for each of the vehicle formations T1 to T3, and is automatically operated by the changeover switch 50 of the leading vehicle formation during the combined operation. A broadcasting device can be selected. For example, as shown in FIG. 6A, the changeover switch 50 is “front (first: corresponding to the automatic broadcasting device 15A of the vehicle formation T1)” and “middle (intermediate: corresponding to the automatic broadcasting device 15B of the vehicle formation T2)”. And “rear (last: automatic broadcasting device 15C of vehicle formation T3)”, only the automatic broadcasting device corresponding to the selected range is turned on, and the rest is turned off. The conductor or driver of the vehicle organization T1 can operate the changeover switch 50 according to the progress of the organization so that an automatic broadcast from an appropriate automatic broadcast device is broadcast to each guest room.

  (Operation 2) Alternatively, a changeover switch is provided at each end of the voice line (leading lines L1, L2 and C) of each vehicle organization so that the on / off of the changeover switch is controlled according to the broadcast pattern. Also good.

For example, as shown in FIG. 6B, a voice line (leading lines L1, L2) in the vehicle formation T1
And C) are respectively provided with changeover switches 50A (SW1) and 50B (SW2) using a relay, for example. Similarly to the vehicle formation T1, the changeover switches 50C (SW1) and 50D (SW2) and the changeover switch 50E (for the vehicle formations T2 and T3 with respect to the audio lines (through lines L1, L2, and C) are also provided. SW1) and 50F (SW2) are provided, respectively.

  The switch SW1 and SW2 for each vehicle composition are configured to be turned on / off by a control signal output via the I / F 24 'from the control device 23 of the automatic broadcast device 15 provided in each vehicle composition. (Figure 2). ON / OFF of each change-over switch SW1 and SW2 is individually controlled at least in the vehicle composition located in the middle, and individual control or one of the change-over switches is turned on / off in the vehicle composition located at the head (tail). Control in which the other is interlocked is possible.

  For example, when the automatic broadcast sound (first broadcast pattern) of the automatic broadcast device 15A of the vehicle formation T1 is broadcast in all vehicle formations, all the changeover switches 50A to 50F of the vehicle formations T1 to T3 are turned on (closed). On the other hand, the automatic broadcast devices 15B and 15C are turned off.

  Alternatively, when the automatic broadcast sound (third broadcast pattern) of the automatic broadcast device 15C of the vehicle organization T3 is broadcast in all vehicle configurations, all the changeover switches 50A to 50F are turned on (closed), while the automatic Broadcasting devices 15A and 15B are turned off.

  By these, the automatic broadcast sound from one automatic broadcast apparatus can be broadcast by all the vehicles of combined organization.

On the other hand, the vehicle organization T2 is the automatic broadcasting device 15A (first vehicle organization T1) or 15C (third
When automatic broadcast audio from one of the vehicle formations T3) is broadcast and the other of the vehicle formations T1 and T3 performs its own automatic broadcast within the self-organization, the following occurs.

  That is, in the vehicle composition T2, the control device 23 of the automatic broadcast device 15B turns on (closes) the selector switch on the side that receives the supply of automatic broadcast audio, and turns off (opens) the opposite side. When receiving automatic broadcast audio from the automatic broadcast device 15A, the changeover switch 50C is turned on and the changeover switch 50D is turned off. When receiving automatic broadcast audio from the automatic broadcast device 15C, the changeover switch 50C is turned off and the changeover switch 50D is turned on. In addition, the automatic broadcast device 15B is in a state where automatic broadcast is not performed (off).

On the other hand, in the vehicle formations T1 and T3, when the automatic broadcast sound is supplied to the vehicle formation T2, at least a change-over switch closer to the second vehicle formation T2 (if the vehicle formation T1, the changeover switch 50B, the vehicle formation If it is T3, the changeover switch 50E) is turned on. On the other hand, when each of the vehicle formations T1 and T3 performs its own automatic broadcast only within its own formation, at least the changeover switch on the side close to the vehicle formation T2 (if the vehicle formation T1, the changeover switch 50B, the vehicle If the train is T3, the changeover switch 50E) is turned off.

  Thus, the same automatic broadcast can be performed on one of the vehicle formations T2 and one of the vehicle formations T1 and T3, while the original automatic broadcast can be performed on the other of the vehicle formations T1 and T3.

  Alternatively, when each of the vehicle trains T1 to T3 performs its own automatic broadcast, each of the automatic broadcast devices 15A, 15B, and 15C turns off (opens) the changeover switches SW1 and SW2 in the own train. . Thereby, it is possible to carry out an independent automatic broadcast for each vehicle organization. In this case, the first to third broadcast patterns can be broadcast for each organization. In this case, on / off of the changeover switch 50A of the vehicle formation T1 and the changeover switch 50F of the vehicle formation T3 is arbitrary.

Control of each change-over switch SW1 and SW2 (50A-50F) mentioned above outputs the control signal with respect to change-over switch SW1 and SW2 according to the broadcast pattern corresponding to an ON / OFF pattern by the control apparatus 23 in each automatic broadcast apparatus 15. Can be realized. That is, the control device 23 controls the changeover switch control information (memory 21) corresponding to the broadcast pattern information.
The switch is controlled based on the information stored in advance. As a result, automatic broadcasting can be independently carried out without sound overlapping between vehicle formations. In the embodiment described above, the case of the combined operation of three vehicle formations has been described. However, according to the configuration of the automatic broadcast system described above, the number of vehicle formations constituting the combined formation can be recognized in each vehicle formation.

  That is, as shown in FIG. 4B, if the combined formation is a combination of two vehicle formations including the first and second vehicle formations T1 and T2, the on / off pattern in each of the vehicle formations T1 and T2 is respectively “110” and “011”. In this way, the number of vehicle formations constituting the combined formation can be determined from the number of off “1”.

  Further, as shown in FIG. 4C, if the first vehicle formation T1 is not in the combined state, the on / off pattern is “111”. Thus, if all are off “1”, this indicates that the vehicle formation is in a single formation state that is not combined. Thereby, the control apparatus 23 can judge that vehicle organization is not combined.

The memory 21 of the automatic broadcast device 15 stores in advance broadcast pattern information corresponding to the number of combined vehicle formations (including a single vehicle), that is, on / off patterns “110” and “111”. By determining broadcast patterns according to these on / off patterns and performing automatic broadcasts, it is possible to carry out automatic broadcasts with fine details according to the number of combined vehicle formations.

  In addition, the table | surface of FIG. 4B and FIG. 4C has shown the on / off pattern when the vehicle organization T1 is made into object. However, as shown in FIGS. 3A and 3B, the connection state between vehicle formation T2 and vehicle formation T3 (configuration of connection portions 42 and 42A) is the same as that of connection portions 41 and 41A. Even when one combined knitting is formed with the knitting T3, the same result as in FIG. 4B is obtained. When the vehicle formations T2 and T3 are each independent, the same result as in FIG. 4C is obtained. Therefore, the automatic broadcast setting according to the number of combined vehicle formations as described above can be performed also in these vehicle formations T2 and T3.

  Further, as in the example shown in FIG. 1, if the number of vehicles constituting the vehicle formation is fixed (three cars in FIG. 1), the total number of vehicles is determined by the control device 23 from the number of vehicle formations constituting the combined formation. Can be recognized. For example, the control device 23 of the vehicle formation T1 can obtain the total number of vehicles according to the on / off pattern. For example, when the on / off pattern “100” is received by the control device 23 of the vehicle composition T1, the control device 23 recognizes that the total number of vehicles is 9, and if it is “110”, it recognizes 6 vehicles. If it is “111”, it can be recognized as three cars. Such a determination process is realized by the control device 23 referring to a table in which the on / off pattern stored in the memory 21 is associated with the number of vehicles. This makes it possible to implement various controls or services according to the number of vehicles when combined.

  The embodiment described above can be modified as follows. For example, as the connection conditions of the connection portions 41 and 41A and the connection portions 42 and 42A shown in FIGS. 3A and 3B, the lowest line is connected to the subsequent highest line, and each remaining line is one in the subsequent line. It was decided to connect to the lower line.

  Alternatively, the uppermost line may be connected to the subsequent lowermost line, and the remaining lines may be connected to the uppermost line in the subsequent process. That is, in FIG. 3A and FIG. 3B, when the vehicle formation T3 is the leading vehicle formation, the connection conditions as described above are applied. For example, the highest (first) detection line D1 in the vehicle formation T3 is connected to the ground line G positioned at the lowest position in the vehicle formation T2. The detection lines D2 and D3 and the ground line G are respectively connected to the detection line D1, the detection line D2, and the detection line D3 of the vehicle organization T2 positioned one level above. Even in such a case, the result in the detection unit 31 (FIG. 2) is not changed.

In the embodiment shown in FIGS. 3A and 3B, the ground line G is arranged at the lowest level, but the ground line G may be provided in any order. For example, the ground line G
3A and 3B, the detection line D1 (second), the detection line D2 (third), and the detection line D3 (fourth, lowest) are also detected by the detection unit 31. There is no change in the on / off pattern.

Second Embodiment
In the first embodiment, as shown in FIGS. 3A and 3B, the ground line G is provided in each of the vehicle formations T1 to T3. However, instead of the ground line G, electric power is supplied (for example, voltage is applied). A line (power supply line P) may be provided.

  For example, as shown in FIG. 7, a power supply line P instead of the ground line G is provided at the lowest position. Each power supply line P is connected to a voltage source 60 as a power supply unit. When detecting the combined state, a voltage is applied only from each voltage source 60. The voltage source 60 may be a current source.

  Then, for example, in the vehicle formation T1, only the FD 32C connected to the detection line D3 is turned on, and the remaining FD 32A and FC 32B are turned off. In this way, the on / off pattern becomes “001” which is the reverse of the example shown in FIG. 3A.

  8A, FIG. 8B, and FIG. 8C show the case where the configuration of the detection lead-in line LD shown in FIG. 7 is applied, when the three-vehicle formation is combined, when the two-vehicle combination is combined, and when there is no combination (single) It is a table | surface which shows the on / off pattern in.

  As shown in FIGS. 8A, 8B, and 8C, in the configuration shown in FIG. 7, the on / off state is the reverse of the case where the configuration shown in FIG. 3A is applied (FIGS. 4A, 4B, and 4C). However, it is not necessary to change the configuration (the control device 23 and the memory 21) after the on / off pattern is detected.

  In the configuration shown in FIG. 7, the number of vehicle formations constituting the combined formation can be determined from the number of OFF “0” in the ON / OFF pattern. Further, when the on / off patterns are all “000” indicating “0”, it can be determined that the self-organization is not combined (independent). Thus, in the second embodiment, as shown in FIG. 8, the configuration described in the first embodiment can be applied as appropriate, except that the logic pattern is opposite to that in the first embodiment. Also in the second embodiment, the configuration of the connecting portions 41A and 42A as shown in FIG. 3B can be applied.

  According to the first and second embodiments described above, in each of the vehicle formations T1 to T3, the position of the self-organization during the combined formation is detected (detected), and automatic broadcasting corresponding to the position is independently performed. Can do. As a result, detailed broadcasting guidance can be provided by automatic broadcasting during combined operation.
