(First embodiment)
A railway vehicle transmission system according to a first embodiment of the present invention and a railway vehicle using the same will be described in detail with reference to the drawings. FIG. 1 is a diagram showing the configuration of a railway vehicle transmission system according to a first embodiment of the present invention. FIG. 2 is a diagram showing the configuration of the transmitter of the railway vehicle transmission system according to the first embodiment of the present invention.

  In the railway vehicle transmission system according to the first embodiment of the present invention, the transmitters 1a to 1c mounted on the train 1 are point-to-point connected through transmission lines 3a to 3d to transmit and receive data. ing. Similarly, the transmitters 1a * to 1c * mounted on the train 2 are point-to-point connected via transmission lines 3a * to 3d * to transmit and receive data. Further, at both ends of the train 1 and the train 2, an electrical coupler 2a, an electrical coupler 2b, an electrical coupler 2a *, and an electrical coupler 2b * for connection with other trains are provided. It is connected to transmitters (1a, 1c, 1a *, 1c *) at both ends of the train 2.

  In the railway vehicle transmission apparatus according to the first embodiment of the present invention, as shown in FIG. 2, the transmitter 1 includes a 2-port trunk transmitter (5a, 5b) and a 2-port trunk receiver (6a, 6b) and a transmission station 7 for exchanging data of the own car, and a transmission repeater control device 4 for controlling each transmission port. The transmission repeater control device 4 is connected to another train. The merge command 8 shown is input. The transmission repeater control device 4 sets the transmission station address in the transmitter based on the merge command shown in the train merge state. The transmission station 7 of the own car may be inside the transmitter 1 or outside the transmitter 1. There may be a plurality of transmission stations 7.

  In the description of the railway vehicle transmission apparatus and the railway vehicle using the same according to the present embodiment, the private address class C of IPV4 is used as the transmission station address, but class B and class A are used. Needless to say, IPV6 or the like may be used.

Next, the operation of the railway transmission system according to the embodiment of the present invention will be described. In the railway vehicle transmission apparatus according to the first embodiment of the present invention, as shown in FIG. 3, when the vehicles are not connected, each transmitter 1 is a default, 192, 168, 0, 1 (transmitter 1a), 192, 168, 0, 2 (transmitter 1b), 192, 168, 0, 3 (transmitter 1c). This default address is common to all train transmitters 1a to 1c, 1a * to 1c *, and 1a ** to 1c **. Note that the default transmission station address of each car may be set by a switch, a signal from a car setting device may be used, setting by outfitting, or a method of assigning in order from the top.

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 coupled together via the electrical coupler 2b and the electrical coupler 2a *, the transmission repeater control device 4 of the transmitter 1c of the third car of the train 1 and the transmitter 1a * of the first car of the train 2 are connected. The transmission command is input from the electrical coupler 2b and the electrical coupler 2a * to the transmission repeater controller 4 (see FIG. 4). The transmission repeater control device 4 of the transmitter 1a * of the train 2 that has detected the merge command 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) Temporary address change request command for temporarily setting a temporary address to 15 to 8 bits in the bit is output to the transmission stations 1b * and 1c * in the train 2. 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. The transmission repeater control device 4 of the transmission stations 1b * and 1c * that has received the temporary address change request command changes the part indicating the organization number of the own transmission station address to the temporary address. The transmission repeater control device 4 of the transmission station 1b * and the transmission station 1C * changes the part indicating the organization number of its own transmission station address to a temporary address, and then returns a change completion response to the transmission station 1a *. As a result, the transmission station address of each transmitter 1 of the train 2 is 192,169,0,1,192,168,0,2,192,168,0,3 to 192,168,255,1,192, It will be changed to 168, 255, 2, 192, 168, 255, 3 (FIG. 5). Thereby, since the transmission station address of the train 2 is a unique address different from the transmission station address of the train 1, it is possible to operate as a single network (FIG. 6).

Next, the transmission repeater control device 4 of the transmission station 1a * of the train 2 detects a portion ("0" in this embodiment) indicating the train number state of the train 1 on the network 1, and transmits the train 2 within the train 2. A request for changing the composition number from the temporary address to the final composition address is issued to the station 1b * 1c *. 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.) (FIG. 7).

Upon receiving the composition number change request from the transmission repeater control device 4 of the transmitter 1a *, the transmission repeater control device 4 of the transmitter 1b * and 1c * changes the portion indicating the composition number state from “255” to “1”. Change and return a change complete response. Finally, the transmission station address of each transmitter 1 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 and unique addresses (FIG. 8).

Next, the case where the train 3 is combined with the train 2 coexisting with the train 1 will be described with reference to FIGS. When the train 3 is combined with the train 2, the transmission repeater control device 4 of the transmitter 1c * of the train 2 of the train 2 and the transmission repeater control device 4 of the transmitter 1a ** of the train 1 of the train 3 are electrically connected. A merge command is input from the coupler 2c * and the electrical coupler 2a **. In the railway vehicle transmission system of the present embodiment, when the trains are combined, the transmission station addresses of the train to which the first car is connected are changed, so the transmission station addresses of the train 1 and the train 2 are As it is, the transmitter address of the train 3 is changed. The transmission station address of train 3 is the default 1a ** = 192,168,0,1, 1b ** = 192,168,0,2,1c ** = 192,168,0,3 ( FIG. 9).

Similar to the combination of train 1 and train 2, transmitters 1a **, 1b **, 1c ** of train 3 are temporarily assigned to temporary addresses 192, 168, 255, 1 (1a **), 192, 168, 255. , 2 (1b **), 192, 168, 255, 3 (1c **). In this state, the transmitters of trains 1 to 3 have unique addresses and form one network. (Fig. 10)
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 train 1 and the train 2 are merged. In the railway vehicle transmission system of the present embodiment, since “1” is used as the formation address in train 2, train 2 uses “2”, which is obtained by adding 1 to the formation address of train 2 as the formation address. become. 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. (Fig. 11)
The railway vehicle transmission system configured as described above can build a network having high redundancy and excellent maintainability.

In the railway vehicle transmission system of the present embodiment, the address of the train on the first car side is changed, but a method of changing the address of the train on the third car side may be used.

Next, the operation when the transmission system is started up with the trains combined will be described with reference to FIGS.

When the trains 1, 2, and 3 are started up together, the transmitters 1a to 1c, 1a * to 1c * and 1a ** to 1c ** of each train are default addresses 192, 168, 0 , 1-192, 168, 03. In this state, the network is in a closed state in the own train and is divided into networks 1 to 3. In this state, since the trains 1 to 3 are already connected, the transmission repeater control device 4 of the transmitter 1c of the train 1, the transmission repeater control device 4 of the transmitter 1a * of the train 2 and the transmission relay of 1c *. The combined command is input from each electrical coupler to the transmission controller 4 and the transmission repeater control device 4 of the transmission station 1a ** of the train 3 (FIG. 12).

Trains 2 and 3 are changed to temporary addresses once because the merge command is input to the first car side. However, since the merge command is also input to the third car side of the train 2, the connection with the train 3 remains disconnected until the address of the own train is determined. As a result, the network is composed of two networks, a network 1 of the train 1-2 and a network 2 of the train 3. Each transmission station address of the network 1 is 1a = 192, 168, 0, 1, 1b = 192, 168, 0, 2, 1c = 192, 168, 0, 3, 1a * = 192, 168, 255, 1, 1b * = 192, 168, 255, 2, 1c * = 192, 168, 255, 3, and the transmission station addresses of the network 2 are 1a ** = 192, 168, 255, 1, 1b ** = 192, 168, 255, 2, 1c ** = 192, 169, 255, 3. (Fig. 13)
Thereafter, the transmission station addresses of the train 2 are changed from the temporary addresses to the final organization addresses as in the case of the combination of the trains 1 and 2, and the transmission station addresses in the network 1 are 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. (Fig. 14)
Next, the transmitter 1c *, which has changed the transmission station address of the train 2, couples the train 3 and the network for connection with the train 3. At this time, since the transmission station address of the train 2 is already the final organization address, the uniqueness of the address is maintained even when the train 2 is connected. (Fig. 15)
Similarly, the train 3 is also connected to the train 2 to change from the temporary address to the final knitting address, and the start-up process for merging the entire knitting is completed. (Fig. 16)
Next, the operation when the train 1-3 starts up with a part of the transmitter down will be described with reference to FIGS. 17 to 20.

FIG. 17 shows each transmission station address when the train 1-3 is started up in a state where the second car transmitter 1b ** of the train 3 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 * = 192,168,1,1,1b * = 192,168,1,2,1c * = 192,168,1,3, 1a ** = 192,168,2,1,1c ** = 192,168,2,3.

In this state, when the transmitter 1b ** that has been down is started up, the transmission station address becomes the default 192, 168, 0, 2 and is the same as the transmission station 1b. (See Figure 18)
For this reason, the transmitter 1a ** once disconnects the network with the train 2 (the transmitter 1a ** has no addresses 192, 168, 2, 2 and therefore it is When the transmission station 1b ** is set up later, a request for changing the composition address is issued. (Fig. 19)
Thereafter, the transmitter 1a ** connects the network with the train 2 again, and the train 1-3 forms one network. The transmission station 1b ** that has started up later becomes 192, 168, 2, and 2 in the end, and the uniqueness of the address can be ensured. (Fig. 20)
In the railway vehicle transmission system of the present embodiment, since the private address class C of IPv4 is used, the organization number assigned to 15 to 8 bits in the lower 16 bits of 4 digits of IPv4 is changed. Although described as a thing, even if it is a system which changes the number assigned to the higher bits using class B or class A to a temporary address, it has the same effect as the transmission system for railway vehicles of this embodiment. Therefore, the present invention is not limited to the transmission system that changes the composition number.

(Second Embodiment)
A railway vehicle transmission system according to a second embodiment of the present invention and a railway vehicle using the same will be described in detail with reference to the drawings.

The railway vehicle transmission system according to the second embodiment of the present invention has the same equipment configuration as that of the first embodiment, but changes the transmission station addresses of both trains that are combined at the time of merging or restarting. This is one of the characteristics.

When the train 1 and the train 2 are combined, the transmission repeater control device 4 of the transmission station 1C of the train 1 and the train 2 and the transmission repeater control device 4 of the transmission station 1a * receive the combination command from the electric coupler. The transmission repeater control device 4 of the transmitter 1c of the train 1 transmits a composition number change request to the transmitter 1a and the transmitter 1b. The transmission repeater control device 4 of the transmitters 1a to 1c adds 1 to the default composition number (“0”) to obtain the composition number of the own machine. After the transmission repeater control device 4 of the transmitter 1c receives the composition number change completion response from the transmitters 1a and 1b, the transmission station 1a * of the train 2 shows the composition number state of the train 1 in the network 1 ("1" in this embodiment) is detected, and a composition number change request from the temporary address to the final composition address is issued to the transmission station 1b * 1c * in the train 2.

Upon receiving the composition number change request from the transmitter 1a *, the transmission repeater control device 4 of the transmitter 1b * and the transmission repeater control device 4 of the 1c * change the composition number status from “255” to “2”. Change and return a change complete response. Finally, the transmission station address of each transmitter 1 is 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 and unique addresses.

  Next, in the railway vehicle transmission system of the present embodiment, the operation when trains 1 to 3 are started up with a part of the transmitter down will be described with reference to FIGS.

Each transmission station address after rising is 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, 1a ** = 192, 168, 3, 1, 1c ** = 192, 168, 3 and 3 (FIG. 21) (the transmission station 1b ** rises later, so there is no address at this point). In this state, when the transmitter 1b ** that has been down is started up, the transmission station address becomes the default 192, 168, 0, 2. In this state, the transmitter 1b ** does not have a final organization address, but since the address does not overlap with other transmitters 1, the uniqueness of the address within the network is maintained. It leans (FIG. 22). The transmitter 1a ** can issue a request for the final organization address to the transmission station 1b ** without disconnecting the network. As a result, the transmission station address of the transmission station 1b ** becomes 192, 168, 3 and 2, and can be changed to the transmission station address having the final organization address (FIG. 23).

The railway vehicle transmission system configured in this way can construct a network having higher redundancy and excellent maintainability than the railway vehicle transmission system of the first embodiment.
