  Hereinafter, embodiments of a knitting and merging system and a merging method according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

Embodiment 1 FIG.
FIG. 1 is a diagram showing a configuration of knitting A in the knitting / combining system according to the present embodiment. In FIG. 1, train formation A is composed of, for example, a plurality of vehicles, and particularly shows a combined vehicle 11a which is one end of the formation A and a vehicle 21a connected thereto. The knitting A can be combined with other knitting not shown.

  A train monitor device 1a is mounted on the combined vehicle 11a of the train A, and the train monitor device 1a includes a central station 3a and a transmission replacement device 2 connected thereto. The train monitor device 1a is a kind of vehicle information device, and collects information (vehicle information) on the state of various devices (devices 4a, 5a, indicators 6a, etc.) mounted on each vehicle of the formation A, and these devices Monitoring. The devices 4a and 5a are, for example, air conditioners and brakes. As will be described later, when the transmission format of the vehicle information is different between the combined formations, the transmission replacement device 2 is configured so that the transmission information in one organization is changed from the transmission format in one organization so that the vehicle information can be replaced. This is a device having a function of converting a transmission format into The transmission replacement device 2 holds, as a table, information regarding transmission formats used in each organization for a plurality of types of organization having different types of organization, and performs conversion of the transmission format based on this table information. In addition, in this Embodiment, although the transmission replacement apparatus 2 is made into a part of structure of the train monitor apparatus 1a, you may mount in the combined vehicle 11a in the form which is not included in the train monitor apparatus 1a.

  An in-vehicle transmission line 7a and an inter-vehicle transmission line 8a are connected to the central office 3a. The central office 3a is connected to the transmission replacement device 2 through the in-vehicle transmission line 7a, and is connected to the devices 4a and 5a and the display 6a in the host vehicle. The central station 3a is connected to a terminal station 16a, which is a train monitoring device 1a mounted on the vehicle 21a, via an inter-vehicle transmission line 8a. That is, the train monitor device 1a is mounted on each vehicle of the formation A, and the combined vehicle 11a is the central station 3a, and the vehicle 21a which is another vehicle is the terminal station 16a. In an intermediate vehicle (for example, vehicle 21a) other than the vehicle (for example, combined vehicle 11a) at both ends of formation A, a terminal station is mounted as train monitor device 1a. Further, the central station or the terminal station can be mounted on the vehicle at the other end of the formation A different from the combined vehicle 11a, and a transmission replacement device may be mounted. Similarly to the central station 3a, the terminal station 16a is connected to the devices 4a and 5a, the display 6a, and the like mounted on the host vehicle via the in-vehicle transmission line 7a. Further, the central station 3a can communicate with the terminal station 16a via the inter-vehicle transmission line 8.

  An inter-vehicle transmission line 80a is drawn from the central office 3a to the connection side. This inter-vehicle transmission line 80a is the same transmission line as the inter-vehicle transmission line 8a. Furthermore, an inter-vehicle transmission line 9a is drawn from the transmission replacement device 2 to the combined side.

  The central office 3a can collect information on the mounted equipment of the entire formation A, and can transmit the collected information to another formation connected together via the inter-vehicle transmission line 80a or the inter-vehicle transmission line 9a. Further, as shown in FIG. 1, in formation A, a lead-through line 10a is disposed across the combined vehicle 11a and the vehicle 21a. This lead-through line 10a is a signal line for transmitting control command information mainly related to safety control such as power running or brake command in the formation A.

  The combined vehicle 11a is provided with a composition type information output unit 70. As will be described later, the knitting type information output unit 70 acquires contact information from the electrical coupler at the time of merging, determines the type of knitting knitted to the knitting A based on this contact information, and stores the information in the central office 3a. Output to. Then, the central station 3a outputs the acquired knitting type information to the transmission replacement device 2. In addition, the structure which provides the function of this organization classification information output part 70 to the central office 3a may be sufficient, for example. In this case, the central office 3a outputs the knitting type information to the transmission replacement device 2 after directly acquiring the contact information from the electrical coupler. In this configuration, there is an advantage that it is not necessary to provide the composition type information output unit 70 separately.

  Next, the operation of the train monitor device 1a will be described. Since the operation at the time of knitting A and other knitting together will be described later, the operation at the time of single knitting of knitting A will be described here. First, information on various devices in the vehicle 21a (devices 4a, 5b, display 6a, etc.) is collected to the terminal station 16a via the in-vehicle transmission line 7a in the vehicle 21a. Information on various devices (devices 4a, 5b, indicator 6a, etc.) in the combined vehicle 11a is collected to the central office 3a via the in-vehicle transmission line 7a in the combined vehicle 11a.

  Subsequently, in order to transmit the information collected in the terminal station 16a to the train monitor device 1a (for example, the central station 3a) mounted on a vehicle other than the vehicle 21a, the terminal station 16a responds to the train monitor device 1a. Edited according to the transmission format for organization A determined by Here, the transmission format generally represents a format of vehicle information at the time of data transmission / reception such as how to arrange pieces of device information. Similarly, the information collected in the central station 3a is also edited in accordance with the transmission format for composition A in the central station 3a for transmission to the terminal station 16a. As a result, the information collected at each of the central station 3a and the terminal station 16a is edited in accordance with the transmission format unified within the organization A.

  The vehicle information edited by the terminal station 16a is transmitted to the central station 3a via the inter-vehicle transmission line 8a. Similarly, the vehicle information edited by the central station 3a is transmitted to the terminal station 16a via the inter-vehicle transmission line 8a. The central station 3a and the terminal station 16a edit the information of the own vehicle and transmit it to the other vehicle, and receive the information from the other vehicle. Thereby, the information of the mounted equipment in the formation A is collected in the central station 3a and the terminal station 16a. The collected vehicle information is provided to the driver or the conductor by displaying it using the display 6a of each vehicle. The central office 3a also plays a role of transmitting vehicle information collected from each vehicle in the formation A to other formations.

  Next, a system configuration when the formation A is combined with other formations will be described. FIG. 2 is a diagram showing a system configuration at the time when the formation B and the formation A mounted with the same type of system as the formation A are combined. In FIG. 2, the formation B is the same type (the formation type) as the formation A, and more specifically, the same type of train monitor device 1b as the vehicle information device (train monitor device 1a) mounted on the formation A is installed. . The difference from the formation A is that the transmission monitoring device 2 is not included in the train monitor device 1b. Specifically, the train monitor device 1b is mounted on each vehicle of the formation B, and the central station 3b of the train monitor device 1b is particularly mounted on the combined vehicle 11b at the formation end. Note that regarding the combined vehicle 11a and the combined vehicle 11b, which is combined / consolidated is a difference in expression and is not essential. In the following, the knitting A is also called the own knitting, and the knitting combined with the knitting A is also called other knitting.

  The central station 3b is connected to a terminal station mounted on the other vehicle of the formation B (not shown) via the inter-vehicle transmission line 8b, and connected to the devices 4b and 5b and the display 6b via the in-vehicle transmission line 7b. It is connected. Further, an inter-vehicle transmission line 80b is drawn from the central office 3b to the combined side. The inter-vehicle transmission line 80b is the same transmission line as the inter-vehicle transmission line 8b.

  Since the train B is equipped with a train monitor device 1b which is the same type of vehicle information device as the train A, the transmission format used for transmitting vehicle information in the train B is the same as the transmission format for the train A It is.

  Further, as shown in FIG. 2, at the time of merging, the inter-vehicle transmission line 80 a drawn from the central station 3 a of the formation A to the formation B side and the inter-vehicle transmission line drawn from the central station 3 b of the formation B to the formation A side. 80 b is connected via the electrical coupler 22. The electrical coupler 22 is to electrically connect the formation A and the formation B so that the two formations can communicate with each other. The electrical coupler 22 is, for example, a male or female coupling portion (not shown) provided at the end of the combined vehicle 11a, and can be connected to or separated from the combined portion of the combined vehicle 11a. It is comprised with the female-type or male-type connection part (not shown) provided in the edge part of 11b.

  Further, in the formation B as well as the formation A, a lead-in wire 10b is provided between the vehicles. The lead-through line 10b is a signal line for transmitting control command information such as a power running or a brake command in the formation B.

  Next, the operation of the system of FIG. 2 will be described. The operation in each knitting is the same as in the case of FIG. For example, with respect to organization A, information of various devices (devices 4a, 5a and display device 6a, etc.) is collected at a central station 3a and a terminal station (not shown), and the information collected at each station is transmitted for organization A. Information edited according to the format and further edited at each station is transmitted and received between the vehicles in the train A via the inter-vehicle transmission line 8a. Thereby, the central station 3a and the terminal station can share the vehicle information in the formation A. The operation of formation B is the same as that of formation A, and vehicle information is transmitted according to the same transmission format as formation A.

  Next, the operation when the formation A and the formation B are combined will be described. First, when the knitting A and the knitting B are mechanically combined, the knitting combined with the knitting A is automatically recognized as the knitting B on the basis of the contact position between the two connecting portions. And the central office 3b are electrically connected via the inter-vehicle transmission line 80a, the electrical coupler 22, and the inter-vehicle transmission line 80b. In addition, the lead-through wire 10 a and the lead-through wire 10 b are connected via the electric coupler 23.

  As described above, the formation A and the formation B are each equipped with the same type of vehicle information device, and therefore employ the same type of system, so various devices (devices 4a, 5a, display 6a, etc.) mounted on the formation A are used. ) And information related to various devices (devices 4b, 5b, display 6b, etc.) mounted in composition B are edited in the same transmission format (transmission format for composition A). Therefore, the transmission format is converted between the two trains by connecting the inter-vehicle transmission line 80a connected to the central station 3a and the inter-vehicle transmission line 80b transmitted to the central station 3b via the electrical coupler 22. It is possible to exchange vehicle information without performing it.

  Here, the contacts of the electrical coupler 22 will be described. FIG. 9 is a diagram illustrating an example of the pin structure of the electrical coupler 22. In FIG. 9, for example, the pin structure of the connecting portion 60 of the combined vehicle 11a is shown, which is composed of, for example, 12 pins. Among these pins, the pin P is a pin for confirming connection, and the pins Q and R are pins for determining the knitting type. For example, when the contact position is only the pin P with respect to the pins P, Q, and R, the formation A is in the combined state, and the combined formation is “knitting B” equipped with the same type of system as the formation A. Is determined. Based on the contact position, the central offices 3 a and 3 b are actually electrically connected by the electrical coupler 22. The vehicle information is transmitted / received via, for example, the pin of pin number 1 in FIG. The knitting type information output unit 70 outputs the knitting type information related to the knitting B to the central station 3a based on the contact information obtained from the electrical coupler 22. Thereby, the central office 3a can recognize the type of the knitting combined with the knitting A.

  FIG. 4 is a diagram showing a data transmission / reception method between organization A and organization B. As described above, since the formation A and the formation B are both equipped with the same type of system, the formation A and the formation B have the same transmission format for data transmission / reception. Therefore, at the time of merging, the central office 3a and the central office 3b can directly communicate to transmit and receive data. For example, the central station 3a can directly transmit information IA, which is vehicle information collected in the formation A, to the central station 3b in the formation B. The same applies to the transmission of the information IB from the central station 3b to the central station 3a.

  In addition, between the trains, the control command information in the train A and the control command information in the train B are exchanged by the lead wire 10a, the electrical coupler 23, and the lead wire 10b.

  Next, as another system configuration when the formation A is combined with another formation, a system configuration when the formation A is combined with a formation C having a different formation type from the formation A will be described. Specifically, the combination of the formation A equipped with the train monitor device 1a as the vehicle information device and the formation C equipped with the train information management device 12 as the vehicle information device will be described. The train information management device 12 is a different vehicle information device from the train monitor device 1a. Therefore, the train set C employs a system different from the train set A.

  FIG. 3 is a diagram showing a system configuration at the time of knitting C with knitting C on which a system different from knitting A is mounted. As shown in FIG. 3, the configuration of the formation A is the same as that of FIG. 1 or FIG. 2, and thus the same components are denoted by the same reference numerals and detailed description thereof is omitted.

  On the other hand, in formation C, a vehicle information management device 12c of a different model from the train monitor device 1a is mounted on the combined vehicle 11c. The vehicle information management device 12c has a function of performing control in addition to the monitoring function of the on-vehicle equipment, and is mounted on each vehicle of the formation C. Further, the combined vehicle 11c is provided with a central device 13 and a terminal device 16 connected thereto as a vehicle information management device 12c. Organization A and organization C employ different systems, and therefore the transmission format for organization A used in organization A and the transmission format for organization C used in organization C are different.

  The vehicle information management device 12c is configured by a redundant system, and is configured by a dual system, for example, in the present embodiment. Specifically, the central device 13 includes a central device 1 system 14 and a central device 2 system 15, and the terminal device 16 includes a terminal device 1 system 17 and a terminal device 2 system 18. Since the vehicle information management device 12c employs a double system configuration, the vehicle information management device 12c has a higher reliability than the train monitor device 1a.

  The central device 13 is connected to various devices (devices 4c, 5c, indicator 6c, etc.) mounted on the combined vehicle 11c via an in-vehicle transmission line 7c, and collects vehicle information related to these devices. The central device 13 can also be mounted on a vehicle at one end different from the combined vehicle 11c in the formation C.

  The terminal device 16 acquires vehicle information related to various devices (devices 34c to 36c and the like) mounted on the combined vehicle 11c. The terminal device 16 has the same function although the device connected to the central device 13 is different, and collects and controls vehicle information related to the on-vehicle device. The terminal device 16 is also mounted on an intermediate vehicle (not shown) of the formation C.

  Central device 1 system 14 is connected to terminal device 1 system 17, and central device 2 system 15 is connected to terminal device 2 system 18. That is, the 1 system or the 2 systems are connected. The central device 1 system 14 is connected to a 1-system vehicle information management device 12c mounted on another vehicle (not shown) via an inter-vehicle transmission line 50c via a terminal device 1 system 17 in the host vehicle. Yes. Similarly, the central device 2 system 15 is connected to the 2 system vehicle information management device 12c mounted on another vehicle (not shown) by the inter-vehicle transmission line 51c via the terminal device 2 system 18 in the host vehicle. ing. Further, an inter-vehicle transmission line 19c is drawn from the central device 1 system 14 to the combined side. This inter-vehicle transmission line 19c is a transmission line similar to the inter-vehicle transmission line 50c. An inter-vehicle transmission line 20c is drawn from the central device 2 system 15 to the combined side. This inter-vehicle transmission line 20c is the same transmission line as the inter-vehicle transmission line 51c. Central device 1 system 14 or central device 2 system 15 also plays a role of transmitting vehicle information collected from each vehicle in formation C to other formations.

  Further, as shown in FIG. 3, at the time of merging, the transmission replacement device 2 and the central device 2 system 15 are connected to the in-vehicle transmission line 9a in the formation A, the electrical coupler 24 between the formations, and the in-vehicle transmission in the formation C. They are connected via a line 20c. Thus, when data collected in the formation C (vehicle information in the formation C) is transmitted to the formation A, the transmission replacement device 2 converts the data in the transmission format for the formation C into the transmission format for the formation A. When the data collected in formation A (vehicle information in organization A) is transmitted to organization C, the vehicle information in the transmission format for organization A is converted into the transmission format for organization C by transmission replacement device 2. Convert to In addition, what is necessary is just to connect the transmission lines 19c and 20c between vehicles of the vehicle information management apparatus 12c directly between formations, when the formations C are combined.

  Further, a lead-in input / output circuit 75 is provided in the coupled vehicle 11c. The lead-in input / output circuit 75 is interposed in the path of the in-vehicle transmission line 10c disposed in the coupled vehicle 11c. One end of the in-vehicle transmission line 10 c is connected to the central device 13. As described above, the train monitor device 1a is a device that only monitors the on-vehicle equipment, and therefore, the control command information is transmitted / received via the through line 10a. On the other hand, the vehicle information management device 12c also controls the on-vehicle equipment. Therefore, when the formation A and the formation C are combined, the lead-through wire 10a and the central device 13 are connected, the central device 13 receives the control command information in the formation A, and the central device 13 The control command is transmitted. However, since the system configurations of the formation A and the formation C are different, the transmission formats of the control command information are also different from each other. Therefore, the passing input / output circuit 75 performs conversion between the transmission format of the control command information in the formation A and the transmission format of the control instruction information in the formation C.

  Next, the operation at the time of single formation of the formation C, particularly the operation of the vehicle information management device 12c will be described. Central device 1 system 14 and central device 2 system 15 collect vehicle information relating to various devices (devices 4c, 5c, indicator 6c, etc.) via in-vehicle transmission line 7c. Further, the terminal device 1 system 17 and the terminal device 2 system 18 collect vehicle information related to various devices (devices 34c to 36c, etc.) via the in-vehicle transmission line 7c.

  Subsequently, the central device 1 system 14 and the central device 2 system 15 edit the collected vehicle information according to the transmission format used in the formation C (transmission format for the formation C). Here, the transmission format for formation C is a format determined according to the vehicle information management device 12, and is different from the transmission format for formation A. Similarly, in the terminal device 1 system 17 and the terminal device 2 system 18, the vehicle information collected in accordance with the transmission format for the formation C is similarly edited. Similarly, vehicle information is collected and edited in the vehicle information management device 12c such as a terminal device mounted on another vehicle in the formation C.

  Next, the vehicle information management device 12c mounted on each vehicle mutually transmits / receives the vehicle information edited via the inter-vehicle transmission paths 50c, 51c, so that the vehicle information in the formation C is transferred to each vehicle. Is shared by the vehicle information management device 12c mounted on the vehicle. Further, the vehicle information in the formation C is displayed / provided to the driver and the conductor using the display 6c.

  Further, the vehicle information management device 12c determines a control command to each device (devices 4c, 5c, devices 34c to 36c, etc.) based on the collected vehicle information, and sends the control command to the in-vehicle transmission line 7c. To each device (devices 4c and 5c, devices 34c to 36c, etc.) and control is performed. In addition, operation | movement of the train monitor apparatus 1a in the formation A is as above-mentioned.

  Next, the operation when the formation A and the formation C are combined will be described. There are mainly two points to be considered in merging between trains having different vehicle information devices and different systems, such as train A and train C. The first is the difference in transmission formats due to different systems. The second is the difference in the functions of the vehicle information device. The vehicle information management device 12 controls not only the onboard equipment but also powering and braking. The command is determined and the control command information is transmitted within the train set C. Hereinafter, the operation will be described with these two points in mind.

  First, when the knitting A and the knitting C are mechanically combined, the knitting combined with the knitting A is automatically recognized as the knitting C on the basis of the contact position between the two connecting portions. 2 and the central device 2 system 15 are electrically connected via the inter-vehicle transmission line 9a, the electrical coupler 24, and the inter-vehicle transmission line 20c. That is, the central office 3 a and the central device 2 system 15 are connected via the transmission replacement device 2. Since the transmission formats at the time of transmission / reception differ between the formation A and the formation C, even if the central station 3a and the central device 1 system 14 are connected as they are, vehicle information cannot be transmitted / received. The transmission / reception device 2 is interposed to convert the transmission format. This is a configuration for solving the first problem in merging between different systems.

  Further, the lead-in wire 10a in the formation A and the in-vehicle transmission line 10c in the formation C are connected via the electrical coupler 23, and the lead-through wire 10a and the central device 13 are connected via the input / output circuit 75. Connected. As will be described later, this is a configuration for solving the second problem.

  Note that the method of automatically recognizing the knitting type based on the contact position between the connecting portions is the same as the method described in the combination of the knitting A and the knitting B. Specifically, with respect to the pins P, Q, and R in FIG. 9, for example, when the contact position is the pin P and the pin Q, the formation A is combined and the combined formation is different from the formation A. It is determined that it is “Knit C” equipped with the system. Based on the contact position, the transmission reading device 2 and the central device 2 system 15 are actually electrically connected by the electric coupler 24. The vehicle information is transmitted / received via, for example, the pin of pin number 2 in FIG. The inter-vehicle transmission line 80a in the formation A and the inter-vehicle transmission line 19c in the formation C are also mechanically connected by a coupler (not shown). By automatically recognizing C, the central station 3a and the central device 1 system 14 are not electrically connected. Thus, the electrical coupler 24 has a structure that determines whether or not to electrically connect the knitting according to the contact position at the time of joining.

  Subsequently, the knitting type information output unit 70 outputs the knitting type information related to the knitting C to the central office 3a based on the contact information obtained from the electrical coupler 24. Thereby, the central office 3a can recognize the type of the knitting combined with the knitting A. Furthermore, the composition type information is transmitted to the transmission / replacement device 2 via the central office 3a, whereby the transmission / replacement device 2 can recognize the composition type combined with the composition A.

  Next, the operation of the transmission reading device 2 will be described with reference to FIG. FIG. 5 is a diagram showing a data transmission / reception method between organization A and organization C. (a) shows a data transmission method from organization A to organization C, and (b) shows organization C to organization A. Shows the data transmission method.

  As shown in FIG. 5 (a), for example, the information IA is created in the train monitoring device 1a in accordance with the transmission format for the formation A, and this information IA is transmitted to the central station 3a and further transmitted from the central station 3a. Transmitted to the device 2. The transmission replacement device 2 holds information relating to the transmission format used in each knitting for a plurality of types of knitting to be merged with the knitting A as a table, and the knitting type information obtained from the knitting type information output unit 70 That is, the transmission format for the formation C is recognized based on the information that the formation C is combined and the table information. Then, the transmission replacement device 2 converts the information IA into information IA 'in the transmission format for the formation C, and transmits this information IA' to the central device 2 system 15 of the vehicle information management device 12c. By such processing, the data collected in the organization A can be used in the organization C.

  Next, as shown in FIG. 5B, the information IC ′ collected by the vehicle information management device 12 c is transmitted from the central device 2 system 15 to the transmission replacement device 2. The information IC 'is edited according to the transmission format for composition C. As described above, since the transmission replacement device 2 recognizes the transmission format of the combined organization C, the information IC ′ is converted into an information IC with the transmission format for the organization A, and this information IC is converted into the train monitoring device 1a. To the central station 3a. By such processing, the data collected in the organization C can be used in the organization A. Note that data is transmitted on the inter-vehicle transmission line 9a in the formation A according to the transmission format for the formation C.

  Since the vehicle information management device 12c of the formation C can also control the mounted equipment, control command information is also collected in the central device 2 system 15. On the other hand, the train monitor device 1a of the formation A only monitors the mounted equipment. Therefore, when vehicle information is transmitted from the central device 2 system 15 to the central station 3a, control command related information that cannot be handled by the central station 3a is determined by the transmission replacement device 2 and is not transmitted to the central station 3a. . Information that is not transmitted from the formation C to the formation A includes, for example, a “compressor activation command”.

  FIG. 6 is a diagram showing an example of conversion of the transmission format by the transmission replacement device 2, and shows an example of conversion from information IA in the transmission format for composition A to information IA ′ in the transmission format for composition C. . As shown in FIG. 6, regarding the information IA collected in the formation A, according to the transmission format for the formation A, “powering information”, “brake information”, and “air conditioning operation information” are all stored in the status st, Information is communicated in units of the status st. On the other hand, regarding the information IA ′ after the replacement of the information IA by the transmission replacement device 2, “powering information” and “brake information” are stored in the same status STa, but the storage order is reversed. Is stored in another status STb. In response to such a difference in the transmission format, the transmission replacement device 2 transmits the information IA ′ in the transmission format for the organization C that can read the information IA transmitted in the transmission format for the organization A in the organization C. Reread.

  Next, a communication procedure between the central office 3a and the transmission replacement device 2 will be described with reference to FIG. FIG. 7 is a diagram illustrating a communication procedure between the central office 3 a and the transmission replacement device 2. As shown in FIG. 7, the central office 3a calls the transmission / reception device 2 at a constant cycle (for example, 10 ms). First, at the time of the first call, the central office 3 a transmits the information I in the organization A to the transmission / replacement device 2. The transmission / replacement device 2 returns a response to this call. That is, at the time of this response, the transmission reading device 2 converts the information i sent from the formation C into a transmission format for the formation A and then transmits it to the central station 3a.

  Subsequently, the information II in the formation A is transmitted from the central office 3a to the transmission / replacement device 2 in the next period after the elapse of a certain period. Will be sent. In this way, transmission / reception of information is repeated between the central office 3a and the transmission / replacement device 2.

  It is preferable to exchange the same kind of information by calling and responding. Further, when the number of information to be transmitted is different between the train monitor device 1a and the vehicle information management device 12c, empty information is transferred from the device with the smaller number of information to be transmitted to the device with the larger number of information to be transmitted. Shall be sent. For example, when information I and information i, which are the same type of information, are exchanged between the central office 3a and the transmission replacement device 2, and the information II is transmitted from the central device 3a in the next cycle, the same type as the information II Is not held by the vehicle information management device 12c, the transmission replacement device 2 transmits information ii, which is empty information, to the central station 3a. As a result, the number of calls is equal to the number of responses, and transmission / reception is simplified by exchanging information including call-response, and the same type of information can be exchanged each time.

  Also, as shown in FIG. 7, when data transmission fails, data is not retransmitted. For example, when the transmission of the information IV from the central office 3a fails, the central office 3a does not receive the call from the central office 3a, and therefore does not transmit the information iv that is a response from the transmission / replacement device 2, and further the central station 3a Also, the information IV is not retransmitted. In this way, a simple data transmission / reception method can be realized between two devices by keeping a certain period.

  Next, the operation of the system will be described in relation to the second problem caused by the different types of vehicle information devices mounted between the combined formations. When the formation A and the formation C are combined, the lead-in wire 10 a in the formation A is connected to the in-vehicle transmission line 10 c in the formation C via the electric coupler 23. As a result, the lead-through line 10 a and the central device 13 are drawn through and connected via the input / output circuit 75.

  As described above, the train monitor device 1a only monitors the mounted equipment in the formation A, whereas the vehicle information management device 12c also controls the vehicle. Therefore, the vehicle information management device 12c cannot obtain the control information of the formation A only by connecting the train monitor device 1a and the vehicle information management device 12c, and also controls the mounted equipment in the formation A. I can't.

  Therefore, the vehicle information management device 12c is connected to the lead-in line 10a in the formation A when combined. However, since the systems are different between formation A and formation C, the control command information transmitted by the lead-through line 10a cannot be taken into the vehicle information management device 12c as it is. For this reason, the control command information transmitted by the lead-through line 10a is converted into a transmission format that can be handled in the formation C through the passing-in input / output circuit 75 provided in the formation C, and then taken into the vehicle information management device 12c. . The vehicle information management device 12c also determines the control command with reference to the control command information from the lead-through line 10a. The vehicle information management device 12c controls not only the on-vehicle equipment in the formation C but also the control command of the on-vehicle equipment in the formation A by outputting a control command to the formation A via the passing input / output circuit 75. Also do. In the formation C, a lead-out line for the formation C (not shown) is also arranged.

  As described above, according to the present embodiment, the formation A on which the transmission read-out device 2 is mounted is both of the same type and different types, such as the combination of the formation A and the formation B and the combination of the formation A and the formation C. It can be combined with the organization equipped with the system. In particular, the formation A can be combined not only with a formation equipped with the same type of vehicle information device, but also with a formation equipped with a different type of vehicle information device. In this way, the knitting between various trains equipped with various vehicle information devices is possible without being limited to the type of vehicle information device at the time of merging.

  Further, according to the present embodiment, the type of the knitting combined with the formation A is determined by the contact positions of the electrical couplers 22 and 24, and the vehicle information device mounted on the formation A and the formation B or the formation C are selected. It is automatically selected whether to connect the mounted vehicle information device via the transmission replacement device 2 or to connect it directly.

  Further, according to the present embodiment, the contact position information of the electrical couplers 22 and 24 is input to the knitting type information output unit 70, and the knitting type information output unit 70 displays the type information regarding the knitting combined with the knitting A. The data is output to the transmission replacement device 2. Based on the composition type information and the table information held by the transmission replacement device 2, the transmission replacement device 2 identifies the transmission format of the composition actually combined with the composition A from the plural kinds of composition that can be combined with the composition A. Can be recognized.

  Further, according to the present embodiment, the transmission / replacement device 2 is provided in the train monitoring device 1a of the formation A, and the input / output circuit 75 is provided in the formation C, whereby each of the formations of the formations A, B, and C is provided. It becomes possible to combine them without any special modification.

  Further, in the present embodiment, when the formation A and the formation C are combined, the transmission reading device 2 and the central device 2 system 15 are connected via the electrical coupler 24. The vehicle information management device 12c is generally composed of a double system, and in this case, the pin numbers for data transmission are different between the 1 system and the 2 system. For example, the inter-vehicle transmission line 19c connected to the central device 1 system 14 uses pin number 1, and the inter-vehicle transmission line 20c connected to the central device 2 system 15 uses pin number 2 (see FIG. 9). ). In formation A, for example, the pin number for data transmission of the inter-vehicle transmission line 80a connected to the central office 3a is 1, and the pin number for data transmission of the inter-vehicle transmission line 9a connected to the transmission replacement device 2 Is 2. That is, the pin number 1 of the inter-vehicle transmission line 80a connected to the central station 3a of the formation A overlaps with the pin number 1 of the inter-vehicle transmission line 19c connected to the central device 1 system 14 of the formation C. . Here, assuming that the vehicle information management device 12c is not a redundant system but includes only the central device 1 system 14 as the central device 13, the transmission format between the central device 1 system 14 and the central station 3a is assumed. Information cannot be directly transmitted / received due to the difference, and communication cannot be performed between the central apparatus 1 system 14 and the transmission / replacement apparatus 2 due to a difference in pin numbers. In this case, in order to enable communication between the central device 1 system 14 and the transmission replacement device 2, for example, it is necessary to provide a pin number switching structure on the knitting A side. There is. Alternatively, as another configuration, a branch point is provided in a configuration in which the central office 3a and the central device 1 system 14 are connected and another transmission line is branched from the transmission line connecting the two to the transmission reading device 2. As a result, the reflected wave is synthesized with the transmission wave, and as a result, distortion of the transmission waveform becomes a problem. On the other hand, in the present embodiment, communication between trains can be performed without any particular modification or the like by using the dual system structure of the vehicle information management device 12c and connecting the second system side to the transmission reading device 2. become.

  Further, according to the present embodiment, by providing the passing input / output circuit 7, control command information can be exchanged between the formation A and the formation C.

In the present embodiment, a combination of the train monitor device 1a and the train monitor device 1a, which is the same type system as the train monitor device 1a installed in the train A but has a different transmission format, will be described. That is, organization A and organization D employ the same type of system, but the transmission formats used are different from each other, so the types of organization are different.

In the formation D, the train monitor device 1d is mounted on the coupled vehicle 11d, and the train monitor device 1d includes a central station 3d. The train monitor device 1d is a vehicle information device having the same function as the train monitor device 1a. The central office 3d is connected to various devices (devices 4d, 5d, indicator 7d, etc.) via an in-vehicle transmission line, and is connected to a train monitor device 1d of another vehicle (not shown) by an inter-vehicle transmission line 8d. Yes. Further, an inter-vehicle transmission line 80c is drawn from the central office 3d to the connection side. Further, the train D is provided with a lead-through line 10 d between the vehicles, and is connected to the train-through line 10 a of the train A by an electrical coupler 23.

  Although organization A and organization D have the same equipment configuration, since the transmission formats used for communication are different, vehicle information cannot be exchanged by connecting central station 3a and central station 3d directly when combined. Therefore, as in the first embodiment, the two central stations 3a and 3d are connected via the transmission / replacement device 2. That is, the central station 3a is connected to the central station 3d via the transmission replacement device 2 via the inter-vehicle transmission line 9a, the electrical coupler 25, and the inter-vehicle transmission line 80c. Note that the read-out operation of the transmission read-out device 2 is the same as that in the first embodiment, and therefore the details are omitted. In FIG. 8, the same components as those in FIG. 2 are denoted by the same reference numerals.

  According to the present embodiment, organization D can be combined with organization A, which is the same type system as organization A but has a different transmission format. Further, the present embodiment and the first embodiment can be combined.
