Description

The present invention relates to a car number setting system and a train that sets the car number of each car of a train in which a plurality of cars are arranged in a straight line.

In order to improve the functionality and service of railway vehicle control and maintenance management, it is being considered and put into practical use to build a communication network in the railway vehicle and manage vehicle control information in the railway vehicle. .. Vehicle control information includes, for example, vehicle control system information such as power running commands and brake commands, monitor system (surveillance system) information such as equipment condition monitoring and surveillance camera images, and service system information such as guidance displays and advertisements. Can be mentioned. In order to manage these vehicle control information, for example, it is necessary to transmit a large amount of data between adjacent vehicles. In recent years, as a data transmission method for railway vehicles, a transmission method using IP technology as a communication network has been adopted (see Patent Document 1).

In Patent Document 1, the vehicle network control device of each vehicle transmits and receives information to and from adjacent vehicles (hereinafter, adjacent vehicles), and the vehicle's own vehicle information and the vehicle mounted on the adjacent vehicle are used. Adjacent vehicle information acquired from the network control device is accumulated as own adjacent vehicle information, and the vehicle network system is a terminal device mounted on each vehicle based on the vehicle information of all vehicles in the vehicle formation obtained from the own adjacent vehicle information.

However, when the above-mentioned vehicle network system is used, each vehicle often has a car number in the train identified by the IP address assigned to the vehicle. Further, the IP address assigned to each vehicle may have a predetermined value that can be set by the vehicle. In such a case, when the vehicle formation is performed, an IP address that cannot be set for the vehicle may be assigned, and the vehicle formation cannot be easily rearranged. Therefore, when the vehicle formation is rearranged using the above network system, it is necessary to newly replace the software used for the network system. Therefore, there is a need for a method that can automatically set the car number with a simple configuration when the vehicle formation is rearranged.

The object of the present disclosure is to provide a technique capable of automatically setting a car number with a simple configuration at the time of vehicle formation (including vehicle reorganization).

In order to solve the above-mentioned problems, the car number setting system of the present invention is a car number setting system that sets a car number for each vehicle based on a predetermined vehicle among a plurality of vehicles connected in a straight line.

Hereinafter, the system of the first embodiment in the present invention will be described with reference to the drawings.

<First Embodiment>
FIG. 1 is a diagram showing an example of a circuit configuration related to setting a car number provided in the train of the vehicle formation of the present embodiment. In FIG. 1, it is assumed that the train runs in the direction of arrow G. The train 10 in the first embodiment is a train of a vehicle formation in which six vehicles 11, 12, 13, 14, 15, and 16 are connected.

As shown in FIG. 1, the vehicle 11 arranged at the head of the train 10 has a power supply device 21 and a transmission line 22 connected to the power supply device 21. The transmission line 22 has a circuit breaker 23, a coil 24, and a diode 25. The circuit breaker 23 is turned on by, for example, operating a start switch (not shown) provided on the vehicle 11. When the circuit breaker 23 is turned on, a current based on the power supplied by the power supply device 21 flows through the transmission line (corresponding to the first transmission line according to claim) 22. The coil 24 generates a magnetic force when an electric current flows through the coil 24. When a magnetic force is generated in the coil 24, the relay switch 35 arranged in the transmission line 34 is turned on. The diode 25 is provided to prevent the current from flowing back.
Further, the vehicle 11 has transmission lines 27, 28, 29, 30. Of these transmission lines 27, 28, 29, 30, the transmission line 27 and the transmission line (corresponding to the second transmission line according to the claim) 28 are connected to the transmission line 22 connected to the power supply device 21. .. When the circuit breaker 23 is turned on, the transmission line 27 and the transmission line 28 supply electric power to the vehicle 11 and the vehicle connected to the vehicle 11 (in this case, the vehicle 12). The transmission line 27 is connected to the transmission line 52a provided in the vehicle 12 when the vehicle 11 and the vehicle 12 are connected to each other. Further, the transmission line 28 is connected to the transmission line 54a provided in the vehicle 12 when the vehicle 11 and the vehicle 12 are connected to each other.

One end of the transmission line 29 and the transmission line 30 is held in the vehicle 11 without being connected to the transmission line 22. The transmission line 29 is connected to the transmission line 55a provided in the vehicle 12 when the vehicle 11 and the vehicle 12 are connected to each other. Similarly, the transmission line 30 is connected to the transmission line 53a provided in the vehicle 12 when the vehicle 11 and the vehicle 12 are connected. Reference numerals 31, 32, and 33 are diodes provided to prevent backflow of current in each of the transmission lines 28, 29, and 30.

The transmission line 34 is connected across the transmission line 28 and the transmission line 29 described above. The transmission line 34 has two relay switches 35 and 36. Of these relay switches 35 and 36, the relay switch 35 is turned on when a magnetic force is generated in the coil 24 described above. Further, the relay switch 36 is turned on when a magnetic force is generated in the coil described later.

The transmission line 28 connects the transmission line 37 on the upstream side of the connection point of the transmission line 34. A coil 38 and a diode 39 are arranged in the transmission line 37 (corresponding to the first transmission line according to the claim). The coil 38 generates a magnetic force when a current flows, and turns on the relay switch of the counter. The diode 39 is provided to prevent the current from flowing back.

The transmission line 29 connects the transmission line 40 on the downstream side of the connection point of the transmission line 34. A coil 41 and a diode 42 are arranged in the transmission line (corresponding to the first transmission line according to claim) 40. The coil 41 generates a magnetic force when a current flows, and turns on the relay switch of the counter. The diode 42 is provided to prevent the current from flowing back.

The transmission line 30 connects the transmission line 43. A coil 44 and a diode 45 are arranged in the transmission line (corresponding to the first transmission line according to the claim) 43. The coil 44 generates a magnetic force when a current flows, and turns on the relay switch of the counter. The diode 45 is provided to prevent the current from flowing back.

The counter 46 has, for example, three relay switches (1R) 47, a relay switch (2R) 48, and a relay switch (3R) 49. Of the three relay switches 47, 48, 49, the relay switch 47 is turned on when a magnetic force is generated in the coil 38. The relay switch 48 is turned on when a magnetic force is generated in the coil 41. Further, the relay switch 49 is turned on when a magnetic force is generated in the coil 44.

The counter 46 is connected to the control device 50. The control device 50 obtains the car number of the own vehicle from the on / off states of the relay switches 47, 48, 49 included in the counter 46. Specifically, the control device 50 converts the on / off state of the relay switches 47, 48, 49 into a binary value. For example, when "1" is set when the relay switch is turned on and "0" is set when the relay switch is turned off, and only the relay switch 47 is turned on, the value based on the counter 46 is the relay. When the switch 47, the relay switch 48, and the relay switch 49 are shown in this order, it is “1,0,0”. The control device 50 reads out the table data TB stored in the storage device 51 and sets the car number. The table data TB is data in which the on / off states of the relay switches 47, 48, 49 and the car number are associated with each other. Table 1 below shows the table data. The set car number is stored in the storage device 51.

Next, the second and subsequent vehicles will be described. Since the circuit configurations for setting the car number are the same for the vehicles 12, 13, 14, 15, and 16 which are the second to sixth vehicles, only the circuit configuration of the second vehicle will be described below. The description of the circuit configuration of the third and subsequent vehicles will be omitted. In FIG. 1, for the same circuit configuration in the second and subsequent vehicles, the second car is the symbol "a", the third car is the symbol "b", the fourth car is the symbol "c", and the fifth car is the symbol "d". ", The sixth car has the symbol" e ".

The vehicle 12 has transmission lines 52a, 53a, 54a, 55a. The transmission line 52a is connected to the transmission line 27 of the vehicle 11. Further, the transmission line 53a is connected to the transmission line 30 of the vehicle 11, the transmission line 54a is connected to the transmission line 28 of the vehicle 11, and the transmission line 55a is connected to the transmission line 29 of the vehicle 11.

These transmission lines 52a, 53a, 54a, 55a connect transmission lines (corresponding to the first transmission line according to claim) 57a, 58a, 59a, 60a connected to the ground. Here, reference numerals 61a, 62a, and 63a are diodes arranged in each of the transmission lines 53a, 54a, and 55a to prevent backflow of current flowing through each transmission line.

The transmission line 57a has a coil 64a and a diode 65a arranged in parallel with the coil 64a. The coil 64a generates a magnetic force when a current flows, and turns on the relay switch 67a arranged in the transmission line 66a connected across the transmission line 53a and the transmission line 54a. The diode 65a is provided to prevent backflow of current. Further, reference numeral 68a is a relay switch that is arranged in the transmission line 66a and is turned on by the magnetic force of the coil 69a described later.

The transmission line 58a is connected to the transmission line 53a on the upstream side of the connection point with the transmission line 66a. The transmission line 58a has a coil 69a and a diode 70a arranged in parallel with the coil 69a. The coil 69a generates a magnetic force when a current flows, and turns on the relay switch 68a arranged in the transmission line 66a and the relay switch 76a arranged in the counter 75a. The diode 70a is provided to prevent backflow of current.

The transmission line 59a is connected to the transmission line 54a on the downstream side of the connection point with the transmission line 66a. The transmission line 59a has a coil 71a and a diode 72a arranged in parallel with the coil 71a. The coil 71a turns on the relay switch 77a arranged on the counter 75a when a current flows. The diode 72a is provided to prevent backflow of current.

The transmission line 60a has a coil 73a and a diode 74a arranged in parallel with the coil 73a. The coil 73a generates a magnetic force when a current flows, and turns on the relay switch 78a arranged on the counter 75a. The diode 74a is provided to prevent backflow of current.

The counter 75a has, for example, three relay switches (1R) 76a, a relay switch (2R) 77a, and a relay switch (3R) 78a. Of the three relay switches 76a, 77a, 78a, the relay switch 76a is turned on by the magnetic force generated in the coil 69a. Further, the relay switch 77a is turned on by the magnetic force generated in the coil 71a. Further, the relay switch 78a is turned on by the magnetic force generated in the coil 73a.

The control device 79a has the same configuration as the control device 50 provided in the vehicle 11. The control device 79a obtains the car number of the own vehicle from the on / off states of the relay switch (1R) 76a, the relay switch (2R) 77a, and the relay switch (3R) 78a arranged in the three counters 75a. Specifically, the control device 79a converts the on / off state of the relay switches 76a, 77a, 78a into a binary value. For example, when only the relay switch 77a is turned on when the relay switch is turned on as "1" and the relay switch is turned off as "0", the control device 79a is based on the counter 75a. The value is "0,1,0" when the relay switches 76a, 77a, and 78a are shown in this order. The control device 79a reads out the table data TB stored in the storage device 80a and sets the car number. The set car number is stored in the storage device 80a.

Next, the flow of setting the car number in the train will be described with reference to FIG. Here, a case where a car number is set for each vehicle will be described with reference to the vehicle 11 which is the leading vehicle.

First, the flow of setting the car number in the leading car 11 will be described. As shown in FIG. 2, for example, when the start switch provided in the conductor room of the leading vehicle 11 is turned on, the circuit breaker 23 is turned on. As a result, electric power is supplied to each vehicle from the electric power supply device 21. In response to the circuit breaker 23 being turned on in the vehicle 11, a current flows through the transmission line 22. The coil 24 generates a magnetic force when a current flows through the transmission line 22. When the coil 24 generates a magnetic force, the relay switch 35 of the transmission line 34 connected across the transmission line 28 and the transmission line 29 is turned on.

As described above, the transmission line 22 connects the transmission line 28 on the upstream side of the coil 24. Therefore, the current flows through the transmission line 22 and then also through the transmission line 28. The transmission line 28 connects the transmission line 37. Therefore, the current also flows through the transmission line 37, and the coil 38 arranged in the transmission line 37 generates a magnetic force. When the coil 38 generates a magnetic force, the relay switch 47 arranged on the counter 46 is turned on.

At this time, no current flows through the transmission lines 29 and 30. As a result, the relay switches 48, 49 of the counter 46 remain off. The control device 50 converts the on / off state of the counter 46 into a value indicated by a binary number. Specifically, in the counter 46, the on / off state of each relay switch is “on”, “off”, and “off” in the order of the relay switch 47, the relay switch 48, and the relay switch 49. Therefore, assuming that "1" is set when the relay switch is turned on and "0" is set when the relay switch is turned off, the binary value obtained from the counter 46 is "1,0,0". Therefore, the control device 50 determines the car number of the vehicle 11 with reference to the table data TB stored in the storage device 51. That is, the car number of the vehicle 11 is set to "1" (see Table 1). The control device 50 stores the car number in the storage device 51.

Next, the flow of setting the car number in the vehicle 12 will be described. The transmission line 52a of the vehicle 12 is connected to the transmission line 27 of the vehicle 11, and the transmission line 53a is connected to the transmission line 30 of the vehicle 11. Further, the transmission line 54a of the vehicle 12 is connected to the transmission line 28 of the vehicle 11, and the transmission line 55a is connected to the transmission line 29 of the vehicle 11.

When the electric power from the vehicle 11 is supplied to the vehicle 12, a current flows through the transmission line 52a and the transmission line 54a. As described above, the transmission line 52a connects the transmission line 57a. Therefore, the current flows through the transmission line 52a to the transmission line 57a. The coil 64a generates a magnetic force when a current flows through the transmission line 57a. When the coil 64a generates a magnetic force, the relay switch 67a arranged in the transmission line 63a and the transmission line 66a connected across the transmission line 54a is turned on.

On the other hand, the transmission line 54a connects the transmission line 59a. Therefore, the current flows through the transmission line 54a to the transmission line 59a. The coil 71a generates a magnetic force when the current flows through the transmission line 59a. When the coil 71a generates a magnetic force, the relay switch 77a arranged on the counter 75a is turned on.

In this case, in the vehicle 12, no current flows through the transmission lines 53a and 55a. That is, in the counter 75a, the relay switch 77a is turned on, but the relay switches 76a and 78a remain off. As a result, in the counter 75a, the on / off state of each relay switch is "off", "on", and "off" in the order of the relay switch 76a, the relay switch 77a, and the relay switch 78a. That is, the value converted from the state of each relay switch of the counter 75a is "0,1,0". The control device 79a determines the car number of the vehicle 12 with reference to the table data TB stored in the storage device 80a. That is, the car number of the vehicle 12 is set to "2" (see Table 1). The control device 79a stores the car number in the storage device 80a.

Next, the flow of setting the car number in the vehicle 13 will be described. The transmission line 52b of the vehicle 13 is connected to the transmission line 52a of the vehicle 12, and the transmission line 53b is connected to the transmission line 55a of the vehicle 12. Further, the transmission line 54b of the vehicle 13 is connected to the transmission line 53a of the vehicle 12, and the transmission line 55b is connected to the transmission line 54a of the vehicle 12.

The vehicle 13 is supplied with electric power from the vehicle 11 via the vehicle 12. When the electric power from the vehicle 11 is supplied to the vehicle 13, the current flows through the transmission line 52b and the transmission line 55b of the vehicle 13. The transmission line 52b connects the transmission line 57b. Therefore, the current flows through the transmission line 52b to the transmission line 57b. The coil 64b generates a magnetic force when a current flows through the transmission line 57b. When the coil 64b generates a magnetic force, the relay switch 67b arranged in the transmission line 63b and the transmission line 66b connected across the transmission line 54b is turned on.

On the other hand, the transmission line 55b connects the transmission line 60b. Therefore, the current flows in the transmission line 60b via the transmission line 55b. The coil 73b generates a magnetic force when the current flows through the transmission line 60b. When the coil 73b generates a magnetic force, the relay switch 78b arranged on the counter 75b is turned on.

In this case, in the vehicle 13, no current flows through the transmission lines 53b and 54b. That is, at the counter 75b, the relay switch 78b is turned on, but the relay switches 76b, 77b remain off. As a result, in the counter 75b, the on / off states of the relay switches are "off", "off", and "on" in the order of the relay switch 76b, the relay switch 77b, and the relay switch 78b. That is, the value converted from the state of each relay switch of the counter 75b is "0, 0, 1". The control device 79b determines the car number of the vehicle 13 with reference to the table data TB stored in the storage device 80b. That is, the car number of the vehicle 13 is set to "3" (see Table 1). The control device 79b stores the car number in the storage device 80b.

Next, the flow of setting the car number in the vehicle 14 will be described. The transmission line 52c of the vehicle 14 is connected to the transmission line 52b of the vehicle 13, and the transmission line 53c is connected to the transmission line 55b of the vehicle 13. Further, the transmission line 54c of the vehicle 14 is connected to the transmission line 53b of the vehicle 13, and the transmission line 55c is connected to the transmission line 54b of the vehicle 12.

The vehicle 14 is supplied with electric power from the vehicle 11 via the vehicles 12 and 13. When the electric power from the vehicle 11 is supplied to the vehicle 13, a current flows through the transmission line 52c and the transmission line 53c of the vehicle 14. The transmission line 52c connects the transmission line 57c. The current flows through the transmission line 52c to the transmission line 57c. The coil 64c generates a magnetic force when the current flows through the transmission line 57c. When the coil 64c generates a magnetic force, the relay switch 67c arranged in the transmission line 63c and the transmission line 66c connected across the transmission line 54c is turned on.

On the other hand, the transmission line 53c branches off the transmission line 58c. Therefore, the current flows through the transmission line 53c to the transmission line 58c. The coil 69c generates a magnetic force when the current flows through the transmission line 58c. When the coil 69c generates a magnetic force, the relay switch 68c arranged on the transmission line 53c and the transmission line 66c connected across the transmission line 54c and the relay switch 76c arranged on the counter 75c are turned on. That is, the current flows from the transmission line 53c to the transmission line 54c via the transmission line 66c. The current also flows through the transmission line 59c connected to the transmission line 54c, and the coil 71c generates a magnetic force. As a result, the relay switch 77c arranged on the counter 75c is turned on.

In this case, in the vehicle 14, no current flows through the transmission line 55c. That is, in the counter 75c, the on / off state of each relay switch is “on”, “on”, and “off” in the order of the relay switch 76c, the relay switch 77c, and the relay switch 78c. That is, the value converted from the state of each relay switch of the counter 75c is "1,1,0". The control device 79c determines the car number of the vehicle 14 with reference to the table data TB stored in the storage device 80c. That is, the car number of the vehicle 14 is set to "4" (see Table 1). The control device 79c stores the car number in the storage device 80c.

Next, the flow of setting the car number in the vehicle 15 will be described. The transmission line 52d of the vehicle 15 is connected to the transmission line 52c of the vehicle 14, and the transmission line 53d is connected to the transmission line 55c of the vehicle 14. Further, the transmission line 54d of the vehicle 15 is connected to the transmission line 53c of the vehicle 14, and the transmission line 55d is connected to the transmission line 54c of the vehicle 14.

The vehicle 15 is supplied with electric power from the vehicle 11 via the vehicles 12, 13, and 14. When the electric power from the vehicle 11 is supplied to the vehicle 15, the current is supplied to the transmission line 52d, the transmission line 54d, and the transmission line 55d of the vehicle 15.

The transmission line 52d connects the transmission line 57d. Therefore, the current flows through the transmission line 52d to the transmission line 57d. When a current flows through the transmission line 57d, the coil 64d generates a magnetic force. When a magnetic force is generated in the coil 64d, the relay switch 67d arranged in the transmission line 63d and the transmission line 66d connected across the transmission line 54d is turned on.

On the other hand, the transmission line 54d connects the transmission line 59d. The current flows through the transmission line 54d to the transmission line 59d. The coil 71d generates a magnetic force when the current flows through the transmission line 59d. When the coil 71d generates a magnetic force, the relay switch 77d arranged on the counter 75d is turned on.

Further, the transmission line 55d is branched from the transmission line 60d. The current flows in the transmission line 60d via the transmission line 55d. The coil 73d generates a magnetic force when the current flows through the transmission line 60d. When the coil 73d generates a magnetic force, the relay switch 78d arranged on the counter 75d is turned on.

In this case, in the vehicle 15, no current flows through the transmission line 53d. Therefore, in the counter 75d, the on / off state of each relay switch is “off”, “on”, and “on” in the order of relay switch 76d, relay switch 77d, and relay switch 78d. That is, the value converted from the state of each relay switch of the counter 75d is “0,1,1”. The control device 79d determines the car number of the vehicle 15 with reference to the table data TB stored in the storage device 80d. That is, the car number of the vehicle 15 is set to "5" (see Table 1). The control device 79d stores the car number in the storage device 80d.

Finally, the flow of setting the car number in the vehicle 16 will be described. The transmission line 52e of the vehicle 16 is connected to the transmission line 52d of the vehicle 15, and the transmission line 53e is connected to the transmission line 55d of the vehicle 15. Further, the transmission line 54e of the vehicle 16 is connected to the transmission line 53d of the vehicle 15, and the transmission line 55e is connected to the transmission line 54d of the vehicle 15.

The vehicle 16 is supplied with electric power from the vehicle 11 via the vehicles 12, 13, 14, and 15. When the electric power from the vehicle 11 is supplied to the vehicle 16, the current flows through the transmission line 52e, the transmission line 53e, the transmission line 54e, and the transmission line 55e of the vehicle 16.

The transmission line 52e connects the transmission line 57e. The current flows through the transmission line 52e to the transmission line 57e. When the current flows through the transmission line 57e, the coil 64e provided in the transmission line 57e generates a magnetic force. When the coil 64e generates a magnetic force, the relay switch 67e arranged in the transmission line 63e and the transmission line 66e connected across the transmission line 54e is turned on.

On the other hand, the transmission line 53e connects the transmission line 58e. The current flows through the transmission line 53e to the transmission line 58e. The coil 69e generates a magnetic force when the current flows through the transmission line 58e. When the coil 69e generates a magnetic force, the relay switch 76e arranged on the counter 75e is turned on. At the same time, the magnetic force generated by the coil 69e turns on the relay switch 68e arranged in the transmission line 63e and the transmission line 66e connected across the transmission line 54e. As a result, the current flowing through the transmission line 53e flows to the transmission line 54e via the transmission line 66e. Here, the transmission line 54e connects the transmission line 59e. The current flows through the transmission line 54e to the transmission line 59e. The coil 71e generates a magnetic force when the current flows through the transmission line 59e. When the coil 71e generates a magnetic force, the relay switch 77e arranged on the counter 75e is turned on.

Further, the transmission line 55e connects the transmission line 60e. The current flows in the transmission line 60e via the transmission line 55e. The coil 73e generates a magnetic force when the current flows through the transmission line 60e. When the coil 73e generates a magnetic force, the relay switch 78e arranged on the counter 75e is turned on.

In this case, in the counter 75e of the vehicle 16, the on / off states of the relay switches are “on”, “on”, and “on” in the order of the relay switch 76e, the relay switch 77e, and the relay switch 78e. That is, the value converted from the state of each relay switch of the counter 75e is "1,1,1". The control device 79e determines the car number of the vehicle 16 with reference to the table data TB stored in the storage device 80e. That is, the car number of the vehicle 16 is set to "6" (see Table 1). The control device 79e stores the car number in the storage device 80e.

In this way, the car number of each vehicle can be set simply by turning on the start switch of the reference vehicle. Therefore, even if the vehicle network system is not used, the car number of each vehicle can be easily set by configuring only the circuit using the relay switch, and the vehicle formation can be easily changed. It is possible to easily set the car number.

In the first embodiment, the case where the car number of each vehicle is set with reference to the vehicle leading in the traveling direction is described, but the vehicle last in the traveling direction may be used as a reference. ..

Further, in the first embodiment, in the first vehicle 11, the transmission line 22 is connected between the circuit breaker 23 and the coil 24, and the transmission line 52 of the second and subsequent vehicles is connected to the transmission line 27 of the vehicle 11. On the other hand, they are connected in series. However, the power supply device 21, the transmission line 22 of the first vehicle, and the transmission line 52 of the second and subsequent vehicles may be connected in parallel. In this case, a circuit breaker is provided between the power supply device 21 and the transmission line 52 of the second and subsequent vehicles, and the circuit breaker of each vehicle is turned on based on the operation of the start switch provided on the reference vehicle. , The car number can be set for each vehicle.

In the first embodiment described above, a diode is arranged in the transmission line of the own vehicle in order to prevent backflow from the transmission line connected to the vehicle in the subsequent stage, but when the diode fails, the car number is changed. Cannot make settings. Therefore, a system in which the car number can be set in each vehicle without arranging a diode for preventing backflow from the transmission line connected to the vehicle in the subsequent stage will be described as the second embodiment.

<Second Embodiment>
Hereinafter, the second embodiment will be described with reference to FIGS. 3 and 4.

Further, the relay switch used in the second embodiment has a contact and b contact, and switches the connection state in response to the supply of electric power to the corresponding coil.

Further, when power is supplied to the corresponding coil, the a contact is closed and the b contact is opened.

Hereinafter, the circuit configuration provided in each vehicle will be described. Since the circuit configurations of the second and subsequent vehicles are the same, only the circuit configurations of the leading vehicle and the second vehicle will be described, and the description of the circuit configurations of the third and subsequent vehicles will be omitted. In addition, in FIGS. 3 and 4, for the same configuration in the second and subsequent vehicles, the second car is the symbol “a”, the third car is the symbol “b”, and the fourth car is the same as in the first embodiment. The symbol "c" is attached to the fifth car with the symbol "d", and the sixth car is given the symbol "e".

The transmission line 157a joins the transmission line 155a on the downstream side of the relay switch 170a.

The transmission line 155a described above branches off the transmission line 171a on the downstream side of the confluence with the transmission line 157a. The transmission line 171a has a coil 172a and a diode 173a. The coil 172a generates a magnetic force when a current flows, and turns on the relay switch 183a arranged on the counter 180a.

The counter 180a has, for example, three relay switches (1R) 181a, a relay switch (2R) 182a, and a relay switch (3R) 183a. Of the relay switches 181a, 182a, and 183a, the relay switch 181a is turned on when the coil 163a generates a magnetic force. Further, the relay switch 182a is turned on when the coil 168a generates a magnetic force. Further, the relay switch 183a is turned on when the coil 172a generates a magnetic force.

The control device 185a obtains the car number of the own vehicle from the on / off states of the relay switch (1R) 181a, the relay switch (2R) 182a, and the relay switch (3R) 183a arranged in the three counters 180a. Specifically, the control device 185a converts the on / off state of the relay switches 181a, 182a, and 183a into a binary value. For example, "1" is set when the relay switch is turned on, and "0" is set when the relay switch is turned off. Therefore, for example, when only the relay switch 182a is turned on, the control device 185a sets the value based on the counter 180a to "0,1,0" when the relay switches 181a, 182a, and 183a are shown in this order. .. The control device 185a reads the table data TB'stored in the storage device 186a and sets the car number. The set car number is stored in the storage device 186a.

Next, the flow of setting the car number in the second embodiment will be described with reference to FIGS. 5 and 6. In the same manner as in the first embodiment, a case where a car number is set for each vehicle based on the vehicle 101 which is the leading vehicle will be described.

First, the flow of setting the car number in the leading car 101 will be described. As shown in FIG. 5, for example, when the start switch provided in the conductor room of the leading vehicle 101 is turned on, the circuit breaker 112 is turned on. As a result, electric power is supplied to each vehicle from the electric power supply device 110. In response to the circuit breaker 112 being turned on in the vehicle 101, a current flows through the transmission line 111. When a current flows through the transmission line 111, the current flows through the transmission line 115 and the transmission line 116 connected to the transmission line 111. Since the transmission line 115 is connected to the transmission line 150a of the vehicle 102, the current flowing through the transmission line 115 flows through the vehicle 102. On the other hand, the transmission line 116 connects the transmission line 119. Therefore, the current flowing through the transmission line 116 flows through the transmission line 119. When a current flows through the transmission line 119, the coil 120 generates a magnetic force. The coil 120 generates a magnetic force to turn on the relay switch 141 of the counter 140.

In the vehicle 101, no current flows through the transmission lines 130, 131, 132. That is, in the relay switch 113 of the transmission line 111, the a contact remains open. Further, the relay switch 114 of the transmission line 111 keeps the b contact closed. As a result, the current does not flow downstream of the transmission line 111. Further, in the relay switch 122 of the transmission line 117 and the relay switch 126 of the transmission line 118, the a contact remains open. As a result, the current does not flow through the transmission lines 117 and 118.

Therefore, at counter 140, relay switches 142, 143 remain off. That is, in the counter 140, the on / off state of each relay switch is "on", "off", and "off" in the order of the relay switch 141, the relay switch 142, and the relay switch 143. The value converted from the on / off state of each relay switch of the counter 140 is “1,0,0”. The control device 144 determines the car number of the vehicle 101 with reference to the table data TB'stored in the storage device 145. That is, the car number of the vehicle 101 is set to "1" (see Table 2). The control device 144 stores the car number in the storage device 145.

Next, the flow of setting the car number in the vehicle 102 will be described. The transmission line 150a of the vehicle 102 is connected to the transmission line 115 of the vehicle 101, and the transmission line 151a is connected to the transmission line 111 of the vehicle 101. Further, the transmission line 152a of the vehicle 102 is connected to the transmission line 116 of the vehicle 101, and the transmission line 153a is connected to the transmission line 117 of the vehicle 101.

When the electric power from the vehicle 101 is supplied to the vehicle 102, a current flows through the transmission line 150a and the transmission line 152a of the vehicle 102. As described above, the transmission line 150a connects the transmission line 155a. Therefore, the current flows through the transmission line 150a to the transmission line 155a.

On the other hand, when a current flows through the transmission line 152a, the coil 176a generates a magnetic force. When the coil 176a generates a magnetic force, the a contact of the relay switch 166a arranged in the transmission line 156a is turned on.

When the current flows through the transmission line 155a, the current flows in the order of the transmission line 155a and the transmission line 156a. Here, the transmission line 156a connects the transmission line 167a. Therefore, the current flows in the transmission line 167a. The coil 168a generates a magnetic force when the current flows through the transmission line 167a. When the coil 168a generates a magnetic force, the relay switch 182a arranged on the counter 180a is turned on.

On the other hand, the a contact of the relay switches 158a and 159a arranged in the transmission line 155a remains open. Further, the a contact of the relay switch 170a arranged on the transmission line 157a remains open. That is, since no electric power flows through the coil 163a arranged in the transmission line 162a and the coil 172a arranged in the transmission line 171a, the coil 163a and the coil 172a do not generate a magnetic force. As a result, in the counter 180a, the relay switches 181a, 183a remain off. That is, in the counter 180a, the on / off state of each relay switch is "off", "on", and "off" in the order of the relay switch 181a, the relay switch 182a, and the relay switch 183a. The value converted from the on / off state of each relay switch of the counter 180a is "0,1,0". The control device 185a determines the car number of the vehicle 102 with reference to the table data TB'stored in the storage device 186a. That is, the car number of the vehicle 102 is set to "2" (see Table 2). The control device 185a stores the car number in the storage device 186a.

The flow of setting the car number in the vehicle 103 will be described. The transmission line 150b of the vehicle 103 is connected to the transmission line 150a of the vehicle 102, and the transmission line 151b is connected to the transmission line 155a of the vehicle 102. Further, the transmission line 152b of the vehicle 102 is connected to the transmission line 161a of the vehicle 102, and the transmission line 153b is connected to the transmission line 156a of the vehicle 102.

The electric power from the vehicle 101 is supplied to the vehicle 103 via the vehicle 102. When the electric power from the vehicle 101 is supplied to the vehicle 103, a current flows through the transmission line 150b and the transmission line 153b of the vehicle 103. As described above, the transmission line 150b connects the transmission line 155b. Therefore, the current flows through the transmission line 150b to the transmission line 155b.

On the other hand, when a current flows through the transmission line 153b, the coil 178b generates a magnetic force. When the coil 178b generates a magnetic force, the a contact of the relay switch 170b arranged on the transmission line 157b is closed.

As described above, the current flows through the transmission line 157b through the transmission line 155b. The transmission line 157b joins the transmission line 155b at the downstream end. The current flows in the order of the transmission line 155b and the transmission line 157b, and then flows through the transmission line 155b. Here, the transmission line 155b connects the transmission line 171b. Therefore, the current flows through the transmission line 171b. The coil 172b generates a magnetic force when the current flows through the transmission line 171b. When the coil 172b generates a magnetic force, the relay switch 183b arranged on the counter 180b is turned on.

On the other hand, the relay switches 158b and 159b provided on the transmission line 155b have the a contact remains open. Further, in the relay switch 166b provided on the transmission line 156b, the a contact remains open. Therefore, no current flows through the transmission line 156b or the transmission line 161b. That is, since no electric power flows through the coil 163b arranged in the transmission line 162b and the coil 168a arranged in the transmission line 167b, the coil 163b and the coil 168b do not generate a magnetic force. As a result, in the counter 180b, the relay switches 181b, 182b remain off.

That is, in the counter 180b, the on / off state of each relay switch is "off", "off", and "on" in the order of relay switch 181b, relay switch 182b, and relay switch 183b. The value converted from the on / off state of each relay switch of the counter 180b is "0, 0, 1". The control device 185b determines the car number of the vehicle 103 with reference to the table data TB'stored in the storage device 186b. That is, the car number of the vehicle 103 is set to "3" (see Table 2). The control device 185b stores the car number in the storage device 186b.

The flow of setting the car number in the vehicle 104 will be described. The transmission line 150c of the vehicle 104 is connected to the transmission line 150b of the vehicle 103, and the transmission line 151c is connected to the transmission line 155b of the vehicle 103. Further, the transmission line 152c of the vehicle 103 is connected to the transmission line 161b of the vehicle 103, and the transmission line 153c is connected to the transmission line 156b of the vehicle 103.

The electric power from the vehicle 101 is supplied to the vehicle 104 via the vehicles 102 and 103. When the electric power from the vehicle 101 is supplied to the vehicle 104, a current flows through the transmission line 150c and the transmission line 151c. As described above, the transmission line 150c connects the transmission line 155c. Therefore, the current flows through the transmission line 150c to the transmission line 155c.

On the other hand, when a current flows through the transmission line 151c, the coil 174c generates a magnetic force. When the coil 174c generates a magnetic force, the relay switch 158c and the relay switch 159c of the transmission line 155c close the a contact. Therefore, the electric power flows through the transmission line 155c. Here, the transmission line 155c connects the transmission line 161c between the relay switch 158c and the relay switch 159c. Therefore, the current flows not only in the transmission line 155c but also in the transmission line 161c.

The transmission line 161c connects the transmission line 162c. The current flowing through the transmission line 161c flows through the transmission line 162c. When a current flows through the transmission line 162c, the coil 163c generates a magnetic force. When the coil 163c generates a magnetic force, the relay switch 181c of the counter 180c is turned on.

Similarly, the transmission line 155c connects the transmission line 171c. The current flowing through the transmission line 155c flows through the transmission line 171c. When a current flows through the transmission line 171c, the coil 172c generates a magnetic force. When the coil 172c generates a magnetic force, the relay switch 183c of the counter 180c is turned on.

Here, the relay switch 166c of the transmission line 156c remains open. That is, the current does not flow through the transmission line 156c. The transmission line 156c connects the transmission line 167c. Since the current does not flow through the transmission line 156c, the coil provided in the transmission line 167c does not generate a magnetic force. Therefore, the relay switch 182c of the counter 180c remains off.

Therefore, in the counter 180c, the on / off state of each relay switch is "on", "off", and "on" in the order of relay switch 181c, relay switch 182c, and relay switch 183c. The value converted from the on / off state of each relay switch of the counter 180c is "1,0,1". The control device 185c determines the car number of the vehicle 104 with reference to the table data TB'stored in the storage device 186c. That is, the car number of the vehicle 104 is set to "4" (see Table 2). The control device 185c stores the car number in the storage device 186c.

The flow of setting the car number in the vehicle 105 will be described. The transmission line 150d of the vehicle 105 is connected to the transmission line 150c of the vehicle 104, and the transmission line 151d is connected to the transmission line 155c of the vehicle 104. Further, the transmission line 152d of the vehicle 105 is connected to the transmission line 161c of the vehicle 104, and the transmission line 153d is connected to the transmission line 156c of the vehicle 104.

The electric power from the vehicle 101 is supplied to the vehicle 105 via the vehicles 102, 103, 104. When the electric power from the vehicle 101 is supplied to the vehicle 105, the current flows through the transmission line 150d, the transmission line 151d, and the transmission line 152d. As described above, the transmission line 150d connects the transmission line 155d. Therefore, the current flows through the transmission line 150d to the transmission line 155d.

The current flows through the transmission line 151d. The coil 174d generates a magnetic force when the current flows through the transmission line 151d. When the coil 174d generates a magnetic force, the a contact of the relay switch 158d and the relay switch 159d provided in the transmission line 155d is closed.

At the same time, the current flows through the transmission line 152d. The coil 176d generates a magnetic force when a current flows through the transmission line 152d. When the coil 176d generates a magnetic force, the b contact of the relay switch 160d provided in the transmission line 155d is opened. At the same time, the a contact of the relay switch 166d provided on the transmission line 156d closes.

As described above, the electric power from the vehicle 101 is supplied to the transmission line 150d. The transmission line 150d connects the transmission line 161d between the relay switch 158d and the relay switch 159d. Therefore, the current flows in the transmission line 161d via the transmission line 155d. Here, the transmission line 161d connects the transmission line 162d. The current is supplied to the transmission line 162d. The coil 163d generates a magnetic force when the current flows through the transmission line 162d. When the coil 163d generates a magnetic force, the relay switch 181d arranged on the counter 180d is turned on.

Further, the current flows through the transmission line 156d. The transmission line 156d connects the transmission line 167d. Therefore, the current flows through the transmission line 167d. The coil 168d generates a magnetic force when the current flows through the transmission line 167d. When the coil 168d generates a magnetic force, the relay switch 182d arranged on the counter 180d is turned on.

At this time, the b contact of the relay switch 160d provided on the transmission line 155d is open, and the a contact of the relay switch 170d provided on the transmission line 157d is open. Therefore, no current flows downstream of the transmission line 155d. At the same time, no current flows through the transmission line 157d. That is, no current flows through the transmission line 171d connecting the transmission line 155d.

Therefore, in the counter 180d, the on / off state of each relay switch is "on", "on", and "off" in the order of relay switch 181d, relay switch 182d, and relay switch 183d. The value converted from the on / off state of each relay switch of the counter 180d is “1,1,0”. The control device 185d determines the car number of the vehicle 105 with reference to the table data TB'stored in the storage device 186d. That is, the car number of the vehicle 105 is set to "5" (see Table 2). The control device 185d stores the car number in the storage device 186d.

The flow of setting the car number in the vehicle 106 will be described. The transmission line 150e of the vehicle 106 is connected to the transmission line 150d of the vehicle 105, and the transmission line 151e is connected to the transmission line 155d of the vehicle 105. Further, the transmission line 152e of the vehicle 106 is connected to the transmission line 161d of the vehicle 105, and the transmission line 153e is connected to the transmission line 156d of the vehicle 105.

The electric power from the vehicle 101 is supplied to the vehicle 106 via the vehicles 102, 103, 104, 105. When the electric power from the vehicle 101 is supplied to the vehicle 106, the current flows through the transmission line 150e, the transmission line 152e, and the transmission line 153e. As described above, the transmission line 150e connects the transmission line 155e. Therefore, the current flows through the transmission line 150e to the transmission line 155e.

The current flows through the transmission line 152e. The coil 178e generates a magnetic force when the current flows through the transmission line 152e. When the coil 178e generates a magnetic force, the b contact of the relay switch 160e provided in the transmission line 155e is opened. Further, the a contact of the relay switch 166e provided on the transmission line 156e is closed.

The current flows through the transmission line 153e. The coil 178e generates a magnetic force when the current flows through the transmission line 153e. When the coil 178e generates a magnetic force, the a contact of the relay switch 170e provided in the transmission line 157e is closed.

As described above, the current flows through the transmission line 155e. The current flowing through the transmission line 155e flows through the transmission line 156e and the transmission line 157e.

The transmission line 156e connects the transmission line 167e. Therefore, the current flowing through the transmission line 156e flows through the transmission line 167e, and the coil 168e provided in the transmission line 167e generates a magnetic force. When the coil 168e generates a magnetic force, the relay switch 182e arranged on the counter 180e is turned on.

The transmission line 157e joins the transmission line 155e on the downstream side. The transmission line 155e connects the transmission line 171e. Therefore, the current flowing through the transmission line 155e flows through the transmission line 171e, and the coil 172e provided in the transmission line 171e generates a magnetic force. When the coil 172e generates a magnetic force, the relay switch 183e arranged on the counter 180e is turned on.

Here, the a contact of the relay switch 158e and the relay switch 159e provided on the transmission line 155e remains open. Therefore, the current does not flow to the transmission line 161e or the transmission line 162e connected to the transmission line 161e via the transmission line 155e. That is, the coil provided in the transmission line 162e does not generate a magnetic force.

Therefore, in the counter 180e, the on / off states of the relay switches are "off", "on", and "on" in the order of the relay switch 181e, the relay switch 182e, and the relay switch 183e. The value converted from the on / off state of each relay switch of the counter 180e is "0,1,1". The control device 185e determines the car number of the vehicle 106 with reference to the table data TB'stored in the storage device 186e. That is, the car number of the vehicle 106 is set to "6" (see Table 2). The control device 185e stores the car number in the storage device 186e.

As described above, also in the second embodiment, as in the first embodiment, the car number of each vehicle can be set only by turning on the start switch of the reference vehicle. Therefore, even if the vehicle network system is not used, the car number of each vehicle can be easily set by configuring only the circuit using the relay switch, and the vehicle formation can be easily changed. It is possible to easily set the car number.

In the second embodiment as well, as in the first embodiment, the case where the car number of each vehicle is set with reference to the vehicle leading in the traveling direction is described, but the last in the traveling direction. The tail vehicle may be used as a reference.

In the first embodiment and the second embodiment, the car number is set for the trains of 6 cars, but it can also be applied to trains of 7 or more cars, for example. Hereinafter, the circuit configuration applied to the 16-car train will be described as the third embodiment.
