Abstract

Disclosed is a train information transmission device wherein respective relay devices opposing each other by the coupling surfaces thereof detect the coupling state of the two compositions of vehicles and transmit data from one of the two coupled compositions to the other composition. When the vehicles included in the two coupled compositions are in the same direction, the relay device of the mentioned one composition does not convert the data to be transmitted from the mentioned one composition to the other composition but transmits the data to the opposing relay device as it is. However, when the vehicles included in the two coupled compositions are in different directions, the relay device converts the data corresponding to the directionality of the other composition and transmits the data to the opposing relay device.

Description

  The present invention relates to an information transmission system mounted on a railway vehicle.

  In railway vehicles, the number of vehicles in a train, the order of trains, and the number of trains that are joined together, such as running multiple trains combined into a single train, or splitting a train into multiple trains. The vehicle direction of the vehicle may change dynamically.

  In particular, from the viewpoint of equipment control, railway vehicles have asymmetrical controls on the left and right or front and rear of the vehicle, such as door control and forward / backward control, and control results differ depending on the direction of the combined train. In some cases, it may be necessary to change the control of the apparatus between the knittings depending on the vehicle direction of each knitting after the merging.

  As a method for changing the control of the apparatus according to the vehicle directions after the merging, for example, a railway vehicle transmission apparatus described in Patent Document 1 is known.

  This equipment is a star-type network railway vehicle transmission device that operates normally as one network even when trains are combined / divided regardless of whether the train direction (sea mountain) is normal or reversed. The transmission repeater detects when the direction (seamount) of the two trains that are combined does not match, and reverses the upstream / downstream relationship of all the vehicles of one train, and the upstream on the network of two trains. / Matched downstream relationship.

Japanese Patent No. 4280155

  In the technique described in Patent Document 1, when the directions of two formations to be combined are inconsistent, it is necessary to reverse the upstream / downstream relationship of all the vehicles in one formation. That is, it is necessary to change all the settings of the transmission apparatus of one organization. In order to cope with the setting change, hardware called a trunk port switch and software for controlling the trunk port switch must be installed in all transmission devices in the train, and all transmission devices are set when they are combined. There is a problem that a communication procedure and a processing procedure for changing are necessary.

  Accordingly, an object of the present invention is to provide a train information transmission device that eliminates the need to change the setting of a control device and a transmission device for each train even when trains having different vehicle directions are combined, and enables communication between trains. And

  In order to solve the above-mentioned problem, the present invention recognizes the direction of each other's knitting vehicles at the time of merging multiple knitting, and if the direction of the vehicles is different, the data to be relayed to the other knitting knitting direction The inter-composition transmission device having the function of transmitting data to the other organization is converted to the contents adapted to the other organization, and is provided at the combined portion of the first vehicle and the last vehicle of each organization.

  Alternatively, at least one transmission device (hereinafter referred to as a composition transmission device) is provided in the vehicle for the purpose of transmitting / receiving or relaying data between the vehicles, and the composition transmission device is connected to the front or rear of the vehicle. Are connected to the in-composition transmission device of the existing vehicle by a transmission path, installed in the same vehicle, and connected to a device involved in train traveling and a control device for issuing a control instruction to the device via a branch line. .

  The intra-composition transmission apparatus performs processing such as relaying data received from one transmission path to the other transmission path, relaying data from the transmission path to the branch line, and relaying data from the branch line to the transmission path.

  Further, a transmission device (hereinafter referred to as an inter-composition transmission device) for relaying data to each of the end portions of the transmission path of the first vehicle and the last vehicle of each train is connected to the other party's train, and the transmission It is connected to the intra-composition transmission device via a road. The in-composition transmission device and the inter-composition transmission device for the leading vehicle and the last vehicle may be the same device having both functions.

  When other trains are joined together, two trains are connected to the joined trains via an inter-compartment transmission device, and the two trains joined together via the inter-compartment transmission device are mutually connected. Send and receive.

  Each inter-compartment transmission device facing at the merged part detects the merged state, and when the two merged vehicles are determined to be in the same direction, the transmission is transmitted from the own-knitted in-knitting transmission device to the in-knitting in-knitting transmission device. The data to be transmitted is transmitted as it is to the opposing inter-set transmission apparatus without being converted in the inter-set transmission apparatus in the merged portion.

  In addition, each inter-set transmission device facing each other at the merged part detects the merged state, and when it is determined that the two merged vehicles are in different directions, the in-knitted transmission device of both merged sets is set before the merge. The data to be transmitted from the self-organizing in-composition transmission device to the other-organization in-composition transmission device without changing the recorded information is converted by the inter-composition transmission device according to the direction of the other organization and the opposite organization To the inter-transmission device.

  According to the present invention, even when knitting with different vehicle directions is combined, it is not necessary to change the settings of the knitting control device and the in-knitting transmission device, and communication between the knitting can be performed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  A first embodiment will be described.

  First, FIG. 1 shows a configuration example of an information transmission system according to the first embodiment.

  In the information transmission system in FIG. 1, a train is composed of a leading vehicle 101, one or more intermediate vehicles 100, and a last vehicle 102. Each vehicle is connected to the in-composition transmission device 2 for transmitting / receiving or relaying data between the vehicles, and the in-composition transmission device 9 for connecting the in-composition transmission device 2 of each vehicle to flow data between the in-composition transmission devices, It is configured to include a control device 990 that issues a control instruction to a device installed in each vehicle or the device, and a branch line 99 that connects the in-car transmission device 2 to the control device or the device 990. Here, the devices include an inverter device, a brake device, an air conditioning device, a door device, a broadcasting device, a display device, and the like.

  The intra-composition transmission device 2 relays data received from the intra-composition transmission path 9 of the vehicle adjacent to one side to the intra-composition transmission path 9 of the vehicle adjacent to the other side, or the branch line 99 from the intra-composition transmission path 9. The data is relayed to the transmission line or the data is relayed from the branch line 99 to the intra-composition transmission line 9.

  Further, at each end of the in-composition transmission path 9 of the first vehicle 101 and the last vehicle 102 of each train, a transmission device that relays data to other trains that are joined together (hereinafter referred to as an inter-train transmission device 200). ) Are connected, and the inter-set transmission apparatus 200 is connected to the intra-set transmission apparatus 2 via the intra-set transmission line 9. The intra-composition transmission device 2 and the inter-composition transmission device 200 of the leading vehicle 101 and the last vehicle 102 may be the same device having both functions.

  When the other trains are combined, two train-to-knitting transmission lines 90 are connected between the combined trains via the train-to-knitting transmission device 200, and are joined together via the train-to-knitting transmission device 200. Two organizations send and receive data to and from each other.

  In all the drawings used in the following description, the description of the control device or device 990 and the branch line 99 that are not directly related to the gist of the present invention is omitted.

  Next, the structure of the two knitting combined in FIGS. 2 and 3 will be described. In the following description, only one intermediate vehicle 100 is described for the sake of simplicity.

  FIG. 2 shows an example in which two combined vehicles are in the same direction. In the following description, the knitting in the forward direction is referred to as the first knitting, and the knitting in the backward direction is referred to as the second knitting. In the combined portion, the last vehicle 102 of the first formation and the leading vehicle 101 of the second formation are connected. In the following description, in each train, the right side from the last vehicle 102 toward the leading vehicle 101 is called the A side, and the left side is called the B side. When they are combined in the same direction, the A side and the B side of the first knitting and the second knitting coincide with each other.

  On the other hand, FIG. 3 shows an example in which two combined trains are in different directions. In the combined portion, the last vehicle 102 of the first formation and the last vehicle 102 of the second formation are connected. When combined in different directions, the A side and the B side of the first knitting and the second knitting are opposite to each other. In FIG. 3, the same applies to the case where the leading vehicle 101 of the first formation and the leading vehicle 101 of the second formation are connected. In the following drawings, in the case of merging in different directions, the last vehicle 102 is represented by merging.

  Here, a case is considered where data having different control contents is transmitted from one knitting to the other knitting on the A side and B side of the knitting. Examples of the control for distinguishing between the A side and the B side of the knitting include door opening / closing control of each vehicle, passenger information display control such as door opening lamp control, door opening / closing guidance, and the like. In the following description, door opening / closing control of each vehicle will be described as an example.

  When the two trains of cars that are combined are in the same direction as each other, as shown in FIG. 4, when data is relayed from one train to the other, inter-composition transmission apparatus 200 relays the data without conversion. That is, if the “A-side data” in FIG. 4 is “A-side door opening command data” that is a command to open the A-side door, the inter-knitting transmission device 200 does not convert the data to the partner knitting “A-side data”. Relay the opening command data. Similarly, “A-side closing command data”, “B-side opening command data”, and “B-side closing command data”, which are commands for closing the A-side door, are also relayed to the partner organization without converting the data.

  On the other hand, in the case where the two trains combined are in different directions, as shown in FIG. 5, when data is relayed from one train to the other, the inter-train transmission apparatus 200 transmits the data to the other train before transmitting it. Convert the data. That is, in FIG. 5, when “A side data” is “A side door opening command data” and “B side data” is “B side door opening command data”, the inter-knitting transmission apparatus 200 The “opening command data” is converted into “B-side opening command data” and then transmitted to the partner organization. Similarly, “A-side closing command data”, “B-side opening command data”, and “B-side closing command data” are also converted from “A side” to “B side”, and “B side” is changed to “A side”. To "side".

  FIG. 14 shows a method of converting the door opening command data described above. Data exchanged between the trains is transmitted in the form of packets 8000. As a format of the packet 8000, for example, a packet conforming to the IEEE 802.3 standard may be used. The packet is composed of a packet header 8001 and packet data 8002, and the opening command data is mounted in the packet data 8002. According to FIG. 14, the packet data 8002 includes fields for mounting A side door opening command and A side door closing command data, B side door opening command and B side door closing command data. When the opening control is performed, the A side door opening command field is set to “1”, and the other fields are set to “0”. The inter-knitting transmission device 200 performs conversion to exchange data of the A-side door opening command and the A-side door closing command with data of the B-side door opening command and the B-side door closing command before transmitting to the counterpart knitting.

  In this way, when the two trains of the combined trains are in different directions, by converting the data with the inter-composition transmission device 200, when the “A-side closing command data” is issued in one train, the other train The knitting is transmitted as “B side door opening command data”, and as a result, the doors on the same side are opened in both knitting.

  Note that the inter-composition transmission apparatus 200 represents the above-described processing by a logical symbol and is implemented as hardware by using an FPGA (Field Programmable Gate Array) or the like, and packet reception, data conversion, and packet transmission are operated in parallel using a network processor. It is possible. Further, the present invention can be realized by software that operates on a computer having a CPU (Central Processing Unit), and a hardware configuration example in that case is shown in FIG.

  In FIG. 7, an inter-composition transmission apparatus 200 accumulates transmission / reception data, a processing program, initial setting information, and log information with an arithmetic apparatus 2000 equipped with a CPU, a cache memory, a main memory, and the like that perform processing of each means. Between trains having a data transmission / reception interface function between a storage device 2003 such as a hard disk, a silicon disk, or a non-volatile memory that stores data and the inter-knitting transmission line 90 via the inter-knitting transmission line 90 The transmission line interface device 2001 and the intra-composition transmission path interface device 2002 having an interface function for data transmission / reception between the intra-composition transmission path 9 and the intra-composition transmission apparatus 2 are configured.

  If necessary, an input device 2004 such as a switch or a keyboard for inputting initial setting items such as an address and an operation mode of a transmission path, and an LED or a liquid crystal panel for confirming the setting items, displaying an operation state or log information An output device 2005 such as may be mounted.

  Further, the intra-composition transmission line 9 and the inter-composition transmission line 90 are an IEEE 802.3 standard compliant LAN, SDH (Synchronous Digital Hierarchy), ATM (Asynchronous Transfer Mode), WTB (Wire Train Bus) standardized by IEC 61375. Wired transmission means such as IEEE802.11 standard-compliant wireless transmission means such as a wireless LAN may be used. Further, other transmission means such as the intra-composition transmission path 9 may be used as the wired transmission means, and the inter-composition transmission path 90 may be the wireless transmission means.

  In addition, when it is combined with other formations, it is necessary for the inter-composition transmission apparatus 200 to determine whether the two combined vehicles are in the same direction or in different directions. As described in Japanese Patent No. 4280155), if the direction combined with the information of the electrical coupler is found, the information may be input to the inter-knitting transmission device 200, or mechanically determined by a pin or the like. If a signal indicating the determination result of the combined direction is output, the signal may be input to the inter-knitting transmission apparatus 200.

  Alternatively, the direction of the vehicle may be manually input when combined with other trains.

  Further, without using the signal from the coupler, the inter-knitting transmission device 200 transmits / receives a packet to / from the other-knitting inter-knitting transmission device 200 via the inter-knitting transmission line 90, thereby changing the direction of the combined knitting. It can also be judged. That is, the inter-set transmission apparatus 200 transmits a packet indicating its own position to the inter-set transmission path 90. The packet indicating the own apparatus position may be transmitted periodically at all times, or may be transmitted continuously for a finite number of times only when a combination with another train is detected. The own apparatus position is information indicating whether the vehicle in which the inter-composition transmission apparatus 200 is installed is the first vehicle 101 or the last vehicle 102, and is a MAC address, an IP address, TCP / IP, or UDP / IP. The own device position may be indicated by an identifier such as a port number to be used, or information indicating the own device position may be mounted in the packet data. After merging with other trains, a packet indicating the own device position transmitted by the partner train-to-knitting transmission device 200 is received via the train-to-knitting transmission path 90, and the direction of the partner train is determined from the information mounted in the packet. Judging.

  The first embodiment has been described above.

  As described above, in the present invention, when a plurality of trains are combined, the orientations of the vehicles in the trains of each other are recognized. By combining the inter-knitting transmission device having the function of transmitting the data to the other party's formation and converting it into the combined contents at the combined portion of the first vehicle and the last vehicle of each formation, the different formations in the vehicle direction are combined. However, it is not necessary to change the setting of the control device for the knitting and the transmission device within the knitting, and communication between the knitting can be performed.

  In the above-described first embodiment, the case where data having different control contents is transmitted from one knitting to the other knitting on the A side and the B side of the knitting has been described. For data with different control contents depending on the direction of travel, when the data is transmitted from one train to the other train, if the direction of two combined trains is different and data conversion is required, This can be realized in the same manner as in the first embodiment.

  Data having different control contents depending on the direction of knitting such as forward or reverse includes, for example, “forward” and “reverse” instructions given to the inverter device that controls the rotation of the electric motor.

  As shown in FIG. 16, when the direction of the two combined trains is the same, the instructions of “forward” or “reverse” are the same for any of the trains. Is not converted.

  On the other hand, as shown in FIG. 17, when the directions of the two combined trains are different, when the “forward” or “reverse” instruction is given to one of the trains, the other train is reversed. Therefore, the inter-composition transmission apparatus 200 converts the data for instructing “forward” into data for instructing “reverse” and transmits the data to another organization, or the data for instructing “reverse”. Is converted into data for instructing “advance” and transmitted to another train.

  As shown in FIG. 18, when the two trains combined together have different orientations, the inter-train transmission apparatus 200 receives the data indicating “forward” received from the other trains as data indicating “reverse”. May be converted into data and transmitted into the own organization, or data indicating “reverse” received from another organization may be converted into data indicating “forward” and transmitted into the own organization.

  Here, for example, the data of the “forward” or “reverse” instruction is provided with a forward instruction or reverse instruction bit in the packet data as in FIG. 14, and the inverter device reads the instruction bit and is instructed. You may make it control corresponding to the direction.

  In the first embodiment described above, when two combined trains are in different directions, the data transmitted from the self-knitting in-knitting transmission device to the other-knitting in-knitting transmission device is formed by the inter-knitting transmission device 200. The data is converted according to the direction of the partner organization before being sent to the partner organization via the inter-transmission line 90, but after receiving from the partner organization, the data is converted according to the direction of the organization. A method of relaying data to the intra-composition transmission apparatus 2 is also conceivable.

  Therefore, a second embodiment will be described next.

  When the two trains of cars that are combined are in the same direction as each other, when data is relayed from one train to the other train, the inter-train transmission apparatus 200 relays the data as it is without conversion, as in the first embodiment. However, when the two trains of the combined trains are in different directions, as shown in FIG. 6, when relaying data from the partner train to the own train, the inter-train transmission device 200 transmits the inter-train transmission path 90 from the partner train. The received data is converted in accordance with the direction of the self-organized vehicle, and the converted data is relayed to the self-organization in-composition transmission apparatus 2.

  The second embodiment has been described above.

  Compared with the first embodiment, the second embodiment performs data conversion instead of the inter-knitting transmission device 200 for the knitting on the sender side, and the inter-knitting transmission device 200 for the knitting on the receiver side. The effect of the invention is the same as that of the first embodiment.

  In the second embodiment described above, a case has been described in which data with different control contents is transmitted from one knitting to the other knitting on the A side and B side of the knitting. For data with different control contents depending on the direction of travel, when the data is transmitted from one train to the other train, if the direction of two combined trains is different and data conversion is required, This can be realized in the same manner as the second embodiment.

  Furthermore, as shown in FIG. 15, as the third embodiment, when the mating partner organization is a knitting in which the inter-composition transmission device 200 is not mounted, when the two-unit trained vehicles are in different directions, When data is relayed from the partner organization to the host organization in the host train transmission device 200 of the host organization, the data received from the partner organization via the inter-set transmission path 90 is converted in accordance with the direction of the host vehicle. When relaying the converted data to the self-organization transmission apparatus 2 and relaying data from the self-organization to the partner train, before transmitting the data to the partner train via the inter-knitting transmission path 90, Data conversion is performed according to the direction.

  An example of a method for determining whether the partner organization to be combined is a knitting in which the inter-set transmission device 200 is not mounted is the inter-set transmission device 200 described in the description of the first embodiment. If a packet to be transmitted to the transmission path 90 to indicate the position of the own apparatus cannot be received from the inter-set transmission path 90, it is determined that the partner set does not have the inter-set transmission apparatus 200.

  Further, when the inter-set transmission apparatus 200 can receive a packet transmitted from the inter-set transmission apparatus 200 to indicate the position of the own apparatus from the inter-set transmission path 90, the inter-set transmission apparatus 200 can perform the first embodiment or the second implementation. The operation shown in the third embodiment is executed when the packet transmitted by the inter-set transmission device 200 of the partner organization to indicate its own position cannot be received from the inter-set transmission path 90. It may be carried out.

  The third embodiment has been described above.

  According to the third embodiment, the first embodiment and the second embodiment can be used as long as the direction of the knitting vehicles can be detected even when the knitting partner knitting does not have the inter-knitting transmission apparatus 200 installed. The same effect can be obtained.

  In the above-described third embodiment, the case where data having different control contents is transmitted from one knitting to the other knitting on the A side and the B side of the knitting has been described. For data with different control contents depending on the direction of travel, when the data is transmitted from one train to the other train, if the direction of two combined trains is different and data conversion is required, This can be realized in the same manner as the third embodiment.

  In the first to third embodiments, data conversion is performed by the inter-set transmission device for data for distinguishing between the A side and the B side (or forward and reverse) of the set when the two sets of combined vehicles are in different directions. In the above, an embodiment for relaying is shown. On the other hand, in the configuration in which the intra-knitting transmission line is duplexed into the 1st system and the 2nd system, the 1st system and the 2nd system may be connected in reverse to each other. Therefore, in the fourth embodiment, in the information transmission system in which the in-composition transmission path is duplexed, the two trains of vehicles that are joined together are coupled in different directions, and the duplexed transmission path systems are connected in reverse to each other. In this case, a method for enabling normal data transmission between trains is shown.

  Hereinafter, a fourth embodiment will be described.

  First, FIG. 8 shows a configuration example of an information transmission system according to the fourth embodiment.

  In the information transmission system in FIG. 8, the train organization is composed of the leading vehicle 101, one or more intermediate vehicles 100, and the last vehicle 102, as in FIG. 1 of the first embodiment. However, as the intra-composition transmission path is made to be a dual configuration of the 1-system internal transmission path 91 and the second-system internal transmission path 92, the intra-composition transmission apparatus is the 1-system internal transmission apparatus 21 and the 2-system internal transmission apparatus. 22, the inter-composition transmission apparatus is connected to the intra-composition transmission paths 91 and 92 of the respective systems. In addition, the inter-set transmission line is connected to the inter-set-to-set inter-set transmission line 95 and the second set-to-set inter-set transmission line 96 to the inter-set-to-set inter-set transmission apparatus 201 and the inter-set-to-set inter-set transmission apparatus 202.

  It should be noted that the equipment or control device 990 and the branch line 99 of each vehicle may be separately connected to the transmission system 21 in the 1st train and the transmission device 22 in the 2nd train, respectively, in a 1-system and 2-system duplex configuration. However, although it may be connected to both the devices 21 and 22 in a single configuration, since it is not directly related to the gist of the present invention, the description is omitted in all the drawings used in the following description.

  1-system and 2-system inter-set transmission device that relays data to other trains joined together at the end portions of transmission lines 91 and 92 in the 1st and 2nd trains of the first vehicle 101 and the last vehicle 102 of each train 201, 202 are connected to each other, and the 1-system and 2-system inter-set transmission devices 201, 202 are respectively connected to the 1-system and 2-system-set transmission apparatus 21, 22 is connected. In addition, the transmission systems 21 and 22 within the 1st and 2nd trains of the first vehicle 101 and the last vehicle 102 and the transmission devices 201 and 202 between the 1st and 2nd trains are the same devices having both functions. Also good.

  When other trains are combined, transmission systems 95 and 96 between the two trains 1 and 2 trains are connected between the joined trains via the transmission systems 201 and 202 between the first train and the second train. The two trains joined together via the transmission systems 201 and 202 between the first and second trains transmit / receive data to / from each other. However, depending on the direction of the two-set trains to be combined, one transmission line 95 between the first trains and the other two-train transmission line 96 between the other sets may be connected.

  Further, in order to transfer data between the transmission system 201 between the first trains 201 and the transmission device 202 between the second trains in the same vehicle, both the devices 201 and 202 are connected by an inter-system transmission path 93.

  In addition, when the last vehicle 102 of the first formation and the last vehicle 102 of the second formation are connected, and when the first vehicle 101 of the first formation and the first vehicle 101 of the second formation are connected, Since the functions of the transmission systems 201 and 202 between the first system and the second system are the same, in the following drawings, the combination of the rearmost vehicles 102 is representatively shown in the case of merging in different directions.

  Here, consider a case where data flowing in the first and second systems in each train is transmitted from one train to the other train.

  When the two trains that are combined are in the same direction, as shown in FIG. 9, when the data is relayed from one train to the other train, the transmission systems 201 and 202 between the first train and the second train are connected to the transmission line. The data received from the transmission line 91 within the first system train is relayed to the transmission line 95 between the first system trains, and the data received from the transmission line 92 within the second system trains is relayed to the transmission line 96 between the second system trains. To do.

  On the other hand, when the two trains of the two trains are in different directions, as shown in FIG. 10, when relaying data from one train to the other train, the transmission systems 201 and 202 between the first train and the second train are The system is converted before sending to the partner organization.

  That is, in FIG. 10, the inter-system 1 transmission unit 201 that has received the 1-system data from the intra-system transmission line 91 transmits the 1-system data to the inter-system transmission apparatus 202 via the inter-system transmission path 93. Then, the transmission system 202 between the two-system trains transmits the one-system data transferred from the transmission system 201 between the first-system trains to the partner train via the transmission system 96 between the two-system trains. Since the transmission line 96 between the two systems of the self-organization is connected to the transmission line 95 between the first system of the partner organization, the one-system data transmitted by the transmission device 202 between the two systems of the self-organization is The transmission device 201 between the first trains is received and relayed to the transmission route 91 within the first train.

  On the other hand, the transmission system 202 between the two-system trains that has received the two-system data from the transmission system 92 within the two-system composition transfers the two-system data to the inter-system composition transmission apparatus 201 via the inter-system transmission path 93, The transmission system 201 between the first trains transmits the second system data transferred from the transmission device 202 between the second trains to the partner train via the transmission passage 95 between the first trains. Since the transmission line 95 between the first system trains of the self-organization is connected to the transmission line 96 between the second system trains of the partner organization, the two-system data transmitted by the transmission device 201 between the first system trains of the self-organization is The transmission system 202 between the two systems is received and relayed to the transmission system 92 within the second system.

  The data exchanged between the above-mentioned formations is transmitted through the transmission line in the form of a packet 8000, as in the first embodiment. As a format of the packet 8000, for example, a packet conforming to the IEEE 802.3 standard may be used.

  The 1-system and 2-system inter-set transmission apparatuses 201 and 202 represent the above-described processing by logical symbols, and are implemented by hardware such as an FPGA (Field Programmable Gate Array), or by using a network processor to receive packets or convert data. It is possible to operate packet transmission in parallel. Further, the present invention can be realized by software operating on a computer having a CPU (Central Processing Unit). FIG. 13 shows a hardware configuration example in that case.

  In FIG. 13, 1-system and 2-system inter-composition transmission apparatuses 201 and 202 store an arithmetic apparatus 2000 equipped with a CPU, a cache memory, a main storage memory, and the like that perform processing of each means, accumulate transmission / reception data, and process programs. And the storage unit 2003 such as a hard disk, a silicon disk, or a non-volatile memory for storing initial setting information and log information, and the other organization 1 via the inter-system transmission line 95 or the inter-system transmission line 96. An inter-set transmission line interface device 2001 having an interface function for data transmission / reception between the inter-set train transmission apparatus 201 or the two-set inter-set transmission apparatus 202, and a one-set-set transmission line 91 or a two-set set transmission line 92. Interface for data transmission / reception to / from the transmission system 21 in the first train or the transmission device 22 in the second train, respectively. Interface function for data transmission / reception between the intra-composition transmission line interface device 2002 having the function of the train and the inter-system transmission line 93 through the inter-system transmission line 93 and the inter-system transmission device 201 or the inter-system transmission device 202 It has an intersystem transmission line interface device 2006.

  If necessary, an input device 2004 such as a switch or a keyboard for inputting initial setting items such as an address and an operation mode of a transmission path, and an LED or a liquid crystal panel for confirming the setting items, displaying an operation state or log information An output device 2005 such as may be mounted.

  In addition, transmission lines 91 and 92 within the 1st and 2nd trains, transmission lines 95 and 96 between the 1st and 2nd trains, and a transmission path 93 between the trains are a LAN or SDH (Synchronous Digital Hierarchy), IEEE 802.3 standard compliant, Wired transmission means such as ATM (Asynchronous Transfer Mode), WTB (Wire Train Bus) standardized by IEC 61375 may be used, or wireless transmission means such as a wireless LAN compliant with the IEEE 802.11 standard may be used. Also good. Further, the transmission lines 91 and 92 within the 1st and 2nd trains and the transmission line 93 between the 2nd trains are different transmissions such as the wired transmission means, and the transmission lines 95 and 96 between the 1st and 2nd trains are different transmissions such as the wireless transmission means. Means may be used.

  It should be noted that, when combined with other trains, the inter-train transmission apparatus 200 needs to determine whether the two trains of vehicles that are joined together are in the same direction or in different directions. This is the same as the description of.

  However, the 1-system and 2-system inter-set transmission devices 201, 202 send packets to the other system 1-system and 2-system inter-set transmission apparatuses 201, 202 via the 1-system and 2-system inter-set transmission paths 95, 96, respectively. By transmitting and receiving, it is also possible to determine the direction of the combined knitting. That is, the transmission systems 201 and 202 between the first and second trains transmit packets indicating their own device positions to the transmission paths 95 and 96 between the first and second trains, respectively. The packet indicating the own apparatus position may be transmitted periodically at all times, or may be transmitted continuously for a finite number of times only when a combination with another train is detected. The self-device position is information indicating whether the vehicle on which the first and second system inter-set transmission devices 201 and 202 are installed is the leading vehicle 101 or the last vehicle 102, and the first and second system inter-set transmission device 201 and 202 are information indicating the system of the transmission path to which the device is connected, and may indicate the position of the own device by an identifier such as a MAC address, an IP address, a port number used in TCP / IP or UDP / IP, or a packet Information indicating the own device position may be mounted in the data. After merging with other trains, receive the packet indicating the own device position transmitted by the transmission device 201, 202 between the 1st and 2nd trains of the partner train via the 1st and 2nd train transmission paths 95, 96, The direction of the opponent-organized vehicle is determined from the information mounted in the packet.

  By the way, in the above-described contents, when the two trains of the combined trains are in different directions, the data to be transmitted from the own train to the partner train is transmitted by the first and second train inter-set transmission devices 201 and 202. Before transmitting to the other organization via the inter-system transmission paths 95 and 96, by transferring the data to the second-system and first-system inter-system transmission devices 202 and 201 via the inter-system transmission path 93, respectively, Although the transmission line is matched to the first or second transmission line, a method is also conceivable in which data is relayed to the in-composition transmission apparatus of the own composition by transferring between the systems in accordance with the direction of the own composition after receiving from the other organization. .

  Therefore, when the two trains of cars that are combined are in the same direction, when the data is relayed from one train to the other, the transmission systems 201 and 202 between the first and second trains do not convert the transmission line system. Relaying as it is is the same as described above. However, when two combined trains are in different directions, as shown in FIG. 11, when relaying data from the partner train to the own train, the first train and the second train The inter-transmission apparatuses 201 and 202 receive the data received from the partner train via the 1-system and 2-system inter-set transmission paths 95 and 96 via the inter-system transmission path 93, respectively. , 201 and the transferred data is relayed to the transmission lines 92 and 91 in the self-organization system 2 and system 1 composition.

  Furthermore, as shown in FIG. 12, when the partner organization to be combined is a knitting in which the transmission systems 201 and 202 between the first and second systems are not mounted, when the two-set vehicles combined are in different directions, In the self-organization 1-system and 2-system inter-compartment transmission devices 201, 202, when data is relayed from the partner organization to the self-organization, 1 is transmitted from the partner organization via the 1-system and 2-system inter-unit transmission paths 95, 96. The data received by the transmission systems 201 and 202 between the second and second trains are transferred to the transmission devices 202 and 201 between the second and first trains via the inter-system transmission path 93, respectively, and transmitted between the second and first trains. The devices 202 and 201 relay the transfer data to the transmission systems 22 and 21 within the second system and the first system composition. When data is relayed from the own organization to the other organization, the data received by the first-system and second-system composition transmission devices 201, 202 via the first-system and second-system composition transmission lines 91, 92 93, respectively, to the transmission systems 202 and 201 between the 2nd and 1st trains, and the transmission data 202 and 201 between the 2nd and 1st trains are transferred to the transmission paths 96 and 95 between the 2nd and 1st trains, respectively. Send.

  As described in the description of the first embodiment, an example of a method for determining whether or not the partner organization to be combined is a knitting in which the transmission systems 201 and 202 between the first and second systems are not mounted. If the other party 1st and 2nd generation inter-set transmission devices 201 and 202 cannot receive the packet transmitted to indicate the position of their own apparatus to the 1st and 2nd set inter-set transmission paths 95 and 96, respectively, It is determined that the transmission systems 201 and 202 between the first and second trains are not installed.

  Further, the transmission systems 201 and 202 between the 1st and 2nd trains transmit the packets transmitted by the 1st and 2nd train transmission devices 201 and 202 of the partner train to indicate their own positions between the 1st and 2nd trains. When receiving from the transmission paths 95 and 96, the operation shown in FIG. 10 or FIG. 11 is performed. When the partner organization cannot receive the packet transmitted to indicate the position of the own device, the operation shown in FIG. 12 is performed. You may do that.

  In the present embodiment, the information transmission system in which the intra-composition transmission path is duplexed has been described. However, the present invention can also be applied to a multiplex transmission system having a triple or higher system. For example, in a quadruple transmission system, when there are A, B, C, and D systems, A systems, B systems, C systems, and D systems are connected between the trains. In this way, data is relayed through the intersystem transmission path. That is, data is relayed between the systems so that an arbitrary system of one knitting combined with a corresponding system of the other knitting is connected.

  The fourth embodiment has been described above.

  As described above, according to the present invention, in the information transmission system in which the transmission lines within a train are duplicated, when a plurality of trains are combined, the orientations of the vehicles of the trains are recognized and the vehicles are connected in different directions. Even when the duplexed transmission line systems are connected in reverse, it is not necessary to change the setting of the control device of the knitting and the transmission device within the knitting, and normal data transmission between the knitting can be performed. it can.
