JP 08-237288 A

  However, when adopting IPV4 (Internet Protocol Version 4) (hexadecimal 4 digits), which is widely used at present, and configuring a network in a railway vehicle with a conventional railway vehicle transmission apparatus, the transmission apparatus and the electrical product It is necessary to provide a large number of switches for address setting in the interior, and the switches must be made small in order to accommodate many switches. Therefore, the registration work of the address of the transmission apparatus is easy to induce a setting error by the worker, the work itself is difficult, and the construction of an easy network in the railway vehicle is a problem.

  In addition, when a plurality of trains are merged or divided, it is necessary to register for each transmission device up to the knitting number information that has not been required to be managed in the past, which causes an increase in work. .

  Therefore, an object of the present invention is to provide a railway vehicle transmission system capable of constructing a network with high redundancy and excellent maintainability, and a railway vehicle using the same.

In order to achieve the above object, the present invention connects a transmission apparatus having a plurality of transmission ports and transmitting data received from any of the ports to a necessary transmission port based on a predetermined instruction. In a railway vehicle transmission system that has a transmission path to perform data transmission / reception within the railway vehicle via a network,
The transmission device includes a transmission repeater control device that controls the transmission port, a transmission station that transmits and receives data to and from the transmission port, and a bypass for maintaining the transmission path even when the transmission repeater control device or the transmission port fails. The transmission repeater control device of each transmission device sets the transmission station address in the transmission device based on the combined information indicating the combined information of the car number and the train even when the bypass device is operated. Features.

  In addition, the present invention is characterized in that the above-described transmission system for a railway vehicle is used for the railway vehicle.

  According to the present invention, it is possible to provide a railway vehicle transmission system capable of constructing a network having high redundancy and excellent maintainability, and a railway vehicle using the same.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the following drawings, the same symbols indicate the same or corresponding parts.

  FIG. 1 is a diagram showing a configuration of a railway vehicle transmission system (and a railway vehicle using the same) according to an embodiment of the present invention. FIG. 2 is a diagram illustrating a configuration of the transmission device of the railway vehicle transmission system according to the present embodiment.

  As shown in FIG. 1, in this embodiment, transmission apparatuses 1a to 1c / 1a ′ to 1c ′ / 1a ″ to 1c ″ are mounted on a railway vehicle, and transmission lines 3a to 3d / 3a ′ to 3d ′ / 3a. Point-to-point connection is performed at “˜3d” to transmit and receive data. In addition, electrical couplers 2a / 2b, 2a '/ 2b', 2a "/ 2b" for merging with other trains are connected to transmission devices at both ends.

  Data transmitted and received by the transmission apparatus 1 (1a to 1c / 1a ′ to 1c ′ / 1a ″ to 1c ″) includes a MAC address, an IP header, a TCP header or a UDP header, and data as illustrated in FIG. It consists of information and CRC check data (FCS).

  As shown in FIG. 2, in the railway vehicle transmission system of the present embodiment, the transmission device 1 includes a 2-port trunk transmitter (5a / 5b), a 2-port trunk receiver (6a / 6b), and the own car. A transmission station 7 for transmitting and receiving data, a transmission repeater control device 4 for controlling each transmission port, and a bypass device 11 for maintaining a transmission path even when a transmission repeater control device, a transmission port, or the like fails, The transmission repeater control device 4 is configured such that a car number 8 indicating the car information of the own car and a combined command 9 indicating the combined state of other trains are input.

  When the transmission device power is normally supplied and the transmission repeater control device and the transmission port are operating normally, the bypass device 11 is in a position (lower side) where the changeover switches S1 to S4 are indicated by solid lines. In the case where the transmission repeater control device or the transmission port does not operate normally due to an abnormality in the power supply of the transmission device or for other reasons, that is, in the case of a failure, the positions where the switches S1 to S4 are indicated by broken lines (upper side) ).

  Note that the transmission station 7 of the own car may be inside the transmission apparatus 1 or outside the transmission apparatus 1. There may be a plurality of transmission stations 7.

  In the description of the railway vehicle transmission system according to this embodiment, the IPV4 private address class C is used as the transmission station address. However, class B or class A may be used, or IPV6 or the like may be used. Needless to say, you can.

  Next, the operation of the railway vehicle transmission system of this embodiment will be described. In the railway vehicle transmission system according to the present embodiment, as shown in FIG. 3, when not combined, each transmission device 1 is the default from car number 8, 192, 168, 0, 1 (transmission device 1a ), 192, 168, 0, 2 (transmission apparatus 1b) and 192, 168, 0, 3 (transmission apparatus 1c). This default address is common to the transmission apparatuses 1a to 1c / 1a 'to 1c' / 1a "to 1c" of all trains. The car number 8 of each car may be set by a switch, using a signal from a car setter, setting by outfitting, or a method of assigning in order from the top.

  The node number of each transmission device is 1 (transmission device 1a), 2 (transmission device 1b), and 3 (transmission device 1c), which is the same as the least significant data of the transmission station address. The node number is included in the transmission right information 10 that permits transmission to each transmission device, and is used to identify the transmission device that has issued the transmission right.

  Next, allocation of transmission station addresses when train 1 and train 2 are combined will be described with reference to FIGS.

  First, when the train 1 and the train 2 are combined, the combined command 9 is input to the transmission device 1c of the third car of the train 1 and the transmission device 1a 'of the first car of the train 2 (FIG. 4).

  The transmission apparatus 1a ′ of the train 2 that has detected the merge command by the transmission apparatus on the first car side is a part indicating the composition number state in the transmission station address in the own train (in this embodiment, the lower 16 digits of the 4-digit IPV4) (Assigned to 15 to 8 bits in the bit) is changed to an address for making a temporary address once. Here, the temporary address is defined as a temporary address that is not used finally, and 255 (FF in hexadecimal) is used in this embodiment. As a result, the transmission station address of each transmission device 1 of the train 2 is from 192, 169, 0, 1/192, 168, 0, 2/192, 168, 0, 3 to 192, 168, 255, 1/192, 168, 255, 2/192, 168, 255, 3 (FIG. 5).

  Thereby, since the transmission station address of the train 2 is a unique address unlike the transmission station address of the train 1, it is possible to operate as a single network (FIG. 6).

  Next, the transmission device 1a ′ / transmission device 1b ′ / transmission device 1c ′ of the train 2 detects a portion (“0” in the present embodiment) indicating the train number state of the train 1 in the network 1, and the temporary address To the final transmission station address 192,169,1,1 / 192,168,1,2 / 192,168,1,3. The final composition address of the train 2 is set to the composition address +1 of the train 1 that does not overlap with the train 1, but may be any other number as long as it is unique. In addition, the address corresponding to the car (the lowest 8 bits) may be changed instead of the organization number (for example, 1a = 192, 168, 0, 1, 1b = 192, 168, 0, 2, 1c = 192) 169, 0, 3, 1a ′ = 192, 168, 0, 4, 1b ′ = 192, 168, 0, 5, 1c ′ = 192, 168, 0, 6 etc.).

  The node numbers of the transmission apparatuses are 4 (transmission apparatus 1a '), 5 (transmission apparatus 1b'), and 6 (transmission apparatus 1c '), which are continuations of 1 to 3 of the train 1 (Fig. 7).

  The transmission station address may be changed by a method in which a parent transmission device (for example, 1a ') takes a request / answer handshake, or a method in which each transmission device changes independently from network information.

  Next, the case where the train 1-2 and the train 3 are combined will be described with reference to FIGS. When the train 3 is combined with the train 1-2, the combination command 9 is input to the transmission device 1c ′ of the third car of the train 2 and the transmission device 1a ″ of the first car of the train 3. In this embodiment, the first car Since the transmission station address of the train on the side, that is, the train 3 is to be changed, the transmission station address of the train 3 is changed without changing the transmission station address of the train 1-2. The addresses are initially default 1a "= 192,168,0,1,1b" = 192,168,0,2,1c "= 192,168,0,3. The node numbers of the respective transmission apparatuses are default 1a "= 1, 1b" = 2, 1c "= 3.

  Similar to the combination of the trains 1 and 2, the transmission devices 1a ", 1b", 1c "of the train 3 are temporarily assigned to the temporary addresses 192, 168, 255, 1 (1a"), 192, 168, 255, 2 (1b "). ), 192, 168, 255, 3 (1c ″). In this state, the transmission devices of trains 1 to 3 have unique addresses and construct one network (FIG. 8).

  Thereafter, the transmission station address of the train 3 is changed from the temporary address to the final transmission station address in the same manner as when the trains 1 and 2 are merged. In the present embodiment, since “1” is used for the train address in the train 2, the train 3 uses “2” as the train address. Finally, each transmission station address is 1a = 192, 168, 0, 1, 1b = 192, 168, 0, 2, 1c = 192, 168, 0, 3, 1a ′ = 192, 168, 1, 1 1b '= 192,168,1,2,1c' = 192,168,1,3, 1a "= 192,168,2,1,1b" = 192,168,2,2,1c "= 192 168, 2, 3

  The node numbers of the respective transmission apparatuses are 1a = 1, 1b = 2, 1c = 3, 1a ′ = 4, 1b ′ = 5, 1c ′ = 6, 1a ″ = 7, 1b ″ = 8, 1c ″ = 9 (FIG. 9).

  In addition, in this embodiment, although the address of the 1st car side train, ie, the train 3, was changed, the method of changing the address of the 3rd car side, ie, the train 1-2, may be used.

  Further, when a plurality of trains change from the combined state to the non-consolidated state, the consolidating command becomes a command indicating the non-consolidating state, so the transmission station address representing the composition number information is changed to the initial state.

  In addition, when multiple trains are started up in a combined state, the transmission station address representing the train number information of the own train starts up in the initial state, and, as described above, based on a combined instruction indicating the combined state of trains. The transmission station address representing the train number information of the own train is changed.

  Next, as another embodiment of the present invention, when the transmission devices of some cars start up from a down state (for example, when the power switches of some car transmission devices are turned off, the power switch is turned on. Will be described with reference to FIGS. 10 to 20.

  FIG. 10 shows each transmission station address when the train 1-3 is started up in a state in which the second car transmission device 1b 'of the train 2 is down. Each transmission station, after rising, obtains a composition address by the above-described method, and finally 1a = 192, 168, 0, 1, 1b = 192, 168, 0, 2, 1c = 192, 168, 0, 3, 1a ′ = 192, 168, 1, 1, 1c ′ = 192, 168, 1, 3, 1a ″ = 192, 168, 2, 1, 1b ″ = 192, 168, 2, 2, 1c ″ = 192,168,2,3.

  In this state, when the down transmission apparatus 1b 'starts up, the transmission station address becomes the default 192, 168, 0, 2 and becomes the same as the transmission station 1b (FIG. 11).

  For this reason, the transmission apparatus 1b 'changes its own transmission station address before joining the network. The transmission apparatus 1b 'waits for the transmission right information 10 from the transmission apparatus 1a'. The transmission right information 10 includes a node number indicating from which transmission device the packet is sent. Since the node number of the transmission apparatus 1a 'is 4, the transmission apparatus 1b' determines that the transmission right from the node number 4 is based on the received transmission right information 10 (FIG. 12). That is, the transmission right information 10 is issued in the order of the transmission device 1a, the transmission device 1b, the transmission device 1c, the transmission device 1a ′, the transmission device 1b ′, the transmission device 1c ′,. Since the transmission right from the transmission apparatus is to be received, this determination can be made. In the case of the packet of the transmission right information 10, the IP header part of the normal data packet shown in FIG. 21 includes at least information indicating that it is a transmission right packet and the node number of the issuing transmission station. The packet is replaced.

  Since the node number included in the transmission right information 10 is 4, the transmission device 1b 'can determine that the own transmission device 1b' belongs to the train 2 instead of the trains 1 and 3. In other words, how many trains are organized by train is determined in advance, or can be found by receiving the information on the network and receiving it. In the case of this embodiment, one train is organized by 3 trains. Therefore, it can be determined that it belongs to the train 2 in this way.

  Therefore, the transmission station 1b 'that has started up changes the transmission station address to 192, 168, 1, 2 and the node number to 5, and participates in the network (FIG. 13).

  In the present embodiment, the transmission station address of the down transmission device is set from the node information included in the transmission right information 10, but when there is only one down transmission device, transmission of each transmission device is performed. It can also be set from the station address.

  FIG. 14 shows the address of each transmission station when the train 1-3 is started up with the No. 2 transmission device 1b / 1b ′ / 1b ″ of each train down. The organization address is acquired by the above-described method, and finally, 1a = 192, 168, 0, 1, 1c = 192, 168, 0, 3, 1a ′ = 192, 168, 1, 1, 1c ′ = 192,168,1,3,1a "= 192,168,2,1,1c" = 192,168,2,3.

  In this state, when the down transmission apparatus 1b / 1b ′ / 1b ′ is started, the transmission station address becomes the default 192, 168, 0, 2 and the transmission station 1b / 1b ′ / 1b ″ is the same. (FIG. 15).

  For this reason, the transmission apparatus 1b / 1b ′ / 1b ″ changes its own transmission station address before joining the network.

  First, the transmission device 1b waits for transmission right information 10 from the transmission device 1a. The transmission right information 10 includes a node number indicating from which transmission device the packet is sent. Since the node number of the transmission device 1a = 1, the transmission device 1b determines that the transmission right from the node number 1 is based on the received transmission right information 10 (FIG. 16).

  The transmission apparatus 1b can determine that the own transmission apparatus 1b belongs to the train 1 because the node number of the transmission right information 10 is 1. Therefore, the transmission station 1b changes the transmission station address to 192, 168, 0, 2 and the node number to 2, and participates in the network.

  Next, the transmission apparatus 1b 'waits for the transmission right information 10 from the transmission apparatus 1a'. The transmission right information 10 includes a node number indicating from which transmission device the packet is sent. Since the node number of the transmission apparatus 1a 'is 4, the transmission apparatus 1b' determines that the transmission right from the node number 4 is based on the received transmission right information 10 (FIG. 17).

  Since the node number of the transmission right information 10 is 4, the transmission device 1 b ′ can determine that the own transmission device 1 b ′ belongs to the train 2. Therefore, the transmission station 1b 'changes the transmission station address to = 192, 168, 1, 2 and the node number to 5, and participates in the network (FIG. 18).

  Further, the transmission device 1b ″ waits for the transmission right information 10 from the transmission device 1a ″. The transmission right information 10 includes a node number indicating from which transmission device the packet is sent. Since the node number = 7 of the transmission apparatus 1a ″, the transmission apparatus 1b ″ determines the transmission right from the node number 7 based on the received transmission right information 10 (FIG. 19).

  Since the node number of the transmission right information 10 is 7, the transmission device 1b ″ can determine that the own transmission device 1b ″ belongs to the train 3. Therefore, the transmission station 1b ″ changes the transmission station address to 192, 168, 2, 2 and the node number to 8, and participates in the network (FIG. 20).

  In this way, each transmission apparatus has 1a = 192, 168, 0, 1, 1b = 192, 168, 0, 2, 1c = 192, 168, 0, 3, 1a ′ = 192, 168 as transmission station addresses. , 1, 1, 1b ′ = 192, 168, 1, 2, 1c ′ = 192, 168, 1, 3, 1a ″ = 192, 168, 2, 1, 1b ″ = 192, 168, 2, 2, 1c "= 192, 168, 2, 3 and the node numbers are 1a = 1, 1b = 2, 1c = 3, 1a '= 4, 1b' = 5, 1c '= 6, 1a" = 7, 1b "= 8 1c ″ = 9 and a unique address.

  The railway vehicle transmission system configured in this way has high redundancy and maintenance because a transmission station address can be automatically allocated even when a plurality of transmission devices are started up later without dividing the network. It is possible to construct a network with excellent performance.
