It is transmitted in the order of 20.

  Here, the primary station 20 is provided with a modem serving as a connection port with stations connected before and after the primary station 20, and as an example in FIG. 1, a transmission line from the train B on the upstream side One modem (modem 2) for connecting is shown. A primary station 10 and secondary stations 11 to 13 mounted on the train B are connected to the modem 2 in a multidrop manner.

  And even if the transmission system of the train B is different from the transmission system of the train A, the primary station 20 discriminates the transmission system of the train B at the time of merging, and between the primary station 10 and the secondary stations 11-13. It has a function as a relay station that enables vehicle information to be exchanged (details will be described later). The primary station 20 is electrically connected to the primary station 10, the secondary station 11, the secondary station 12, and the secondary station 13 when the coupler 3 interposed between the train A and the train B is connected.

  Next, with reference to FIG. 2, the operation | movement at the time of the joint of the train A and the train B is demonstrated.

  First, before the connection detection line 4 is connected, the primary station 20 mounted on the train A is on standby as a secondary station of the train B. When the connection detection line 4 is connected, the primary station 10 detects the connection with the train A (step S101), and the primary station 20 detects the connection with the train B (step S102).

  The primary station 10 transmits a polling signal to the primary station 20 (sequence SQ101), and the primary station 20 transmits the polling signal from the primary station 10 within a predetermined period after the connection is detected. It is determined whether or not it has been received.

  If the primary station 20 receives the polling signal within the predetermined period, the primary station 20 determines that the connection partner is the train B (step S103). Then, primary station 20 returns a response signal indicating that the connection partner is determined to be train B (sequence SQ102). This response signal includes information on the number of both trains A.

  When the polling signal from the primary station 10 does not reach the primary station 20 within a predetermined period (sequence SQ103), the primary station 20 is organized so that the connection partner adopts the same transmission method as the train A. Judge that there is.

  In parallel with the operations of SQ101 and SQ102, the primary station 20 transmits a polling signal to the primary station 10 (sequence SQ101 ′), and the primary station 10 is within a predetermined period after the connection is detected. Then, it is determined whether or not a polling signal from the primary station 20 has been received.

  When the primary station 10 receives the polling signal within the predetermined period, the primary station 10 determines that the connection partner is the train A (step S103 '). Then, the primary station 10 returns a response signal indicating that the connection partner is determined to be the train A (sequence SQ102 '). This response signal includes information on the number of both trains B.

  When the polling signal from the primary station 20 does not reach the primary station 10 within a predetermined period (sequence SQ103 ′), the primary station 10 is organized so that the connection partner adopts the same transmission method as the train B. It is judged that.

  Here, in the combined train (train A + train B), the central station mounted on the leading vehicle 2a of the upstream train functions as the primary station of the entire train, and the second vehicles (2b-2d, 1a- In general, the terminal station mounted in 1d) functions as a secondary station. Therefore, the primary station 10 shown in FIG. 1 functions as a primary station in the entire organization.

And the primary station 10 grasps | ascertains that it is the vehicle information from the secondary station 23 with reference to transmission source information.

  Next, a case where vehicle information is transmitted from the primary station 10 of the train B to the secondary station 23 of the train A will be described. The primary station 10 knows the station numbers of the primary station 20, the secondary station 21, the secondary station 22, and the secondary station 23.

Accordingly, the primary station 10 transmits the vehicle information together with the station number 14 that is the destination information by the broadcast method. The same applies when the vehicle information is transmitted from the secondary station 11, the secondary station 12, or the secondary station 13 of the train B to the secondary station 23 of the train A. In this way, the primary station or the secondary station mounted on the train B performs information transmission by regarding the primary station mounted on the combined vehicle 1a of the train A as a self-organized secondary station.

  In the primary station 20 that has received the destination information and the vehicle information, the station number 14 is replaced with the station number 04 and the vehicle information is transmitted to the adjacent secondary station 21. And this vehicle information is sequentially transmitted to the secondary station 21-the secondary station 23 with a bucket relay system.

  According to the vehicle information monitoring apparatus according to the present embodiment, a part of the secondary station in the train B looks as if it is mounted on the combined vehicle 1a of the train A. That is, the primary station 20 appears to be a secondary station with a station number 11 that can transmit vehicle information from the train B by the broadcast method. Similarly, the secondary station 21 appears as a secondary station with station number 12, the secondary station 22 appears as a secondary station with station number 13, and the secondary station 23 appears as a secondary station with station number 14.

  However, even in this case, the primary station 20 functions as a primary station between the secondary station 21, the secondary station 22, and the secondary station 23 in the train A.

  As described above, when the train B is connected to the upstream side of the train A, the primary station 20 mounted on the combined vehicle 1a of the train A is transmitted by the bucket relay method which is the first transmission method. The information from the secondary stations 21 to 23 in the formation A is converted into broadcast information that is the second transmission method and transmitted to the primary station 10 or the secondary stations 11 to 13 of the other formation B, and The information from the primary station 10 or the secondary stations 11 to 13 of the other organization B transmitted by the transmission method 2 is converted into the information of the transmission method of the first transmission method to convert the secondary station 21 of the own organization A. To ~ 23.

It is transmitted in the order of 33.

  On the other hand, when the vehicle information is transmitted from the secondary station 33 to the primary station 30, the vehicle information from the secondary station 33 is based on the destination information, the secondary station 32, the secondary station 31, and the primary station. It is transmitted in the order of 30.

  Here, the secondary station 33 is provided with a modem 1 that connects a transmission line from the train B on the downstream side. A primary station 40 and secondary stations 41 to 43 mounted on the train B are connected to the modem 1 in a multidrop manner.

  And even if the transmission system of the train B is different from the transmission system of the train A, the secondary station 33 discriminates the transmission system of the train B at the time of merging, and between the primary station 40 and the secondary stations 41 to 43. It has a function that enables vehicle information exchange. The secondary station 33 is connected to the primary station 40, the secondary station 41, the secondary station 42, which are mounted on the train B when the coupler 3 interposed between the train A and the train B is connected. And the secondary station 43 is electrically connected.

  Next, the configuration of the train B will be described. The train B shown in FIG. 3 has the same basic configuration as the train B shown in FIG. 1. As an example, the combined vehicle 6a combined with the combined vehicle 5d of the up-side train A and other than the combined vehicle Vehicle 6b-6d which is the vehicle of this.

  In addition to the primary station 40, which is the central station, a vehicle 6a and a monitor display (not shown) are mounted on the vehicle 6a. The primary station 40 is connected to an in-vehicle transmission path (not shown), and is connected to a device, a monitor display, and the like in the host vehicle via the in-vehicle transmission path.

  The primary station 40 is a kind of vehicle information device, and collects and manages vehicle information related to the status of various devices mounted on the vehicles 6a to 6d of the train B, and also monitors each device via a monitor indicator. A function to notify the crew of the state of the vehicle. The vehicle information collectively managed by the primary station 40 is, for example, speed information detected and collected by each vehicle, a door opening command, and the like, similar to the primary station 30.

  A secondary station 41, which is a terminal station, is mounted on the vehicle 6b of the train B. Similarly, a secondary station 42 is mounted on the vehicle 6c, and a secondary station 43 is mounted on the vehicle 6d. In-vehicle transmission lines (not shown) are connected to the secondary stations 41 to 43, respectively, and the secondary stations 41 to 43 are connected to devices in the own vehicle via the in-vehicle transmission lines.

The stations 43 are connected by an inter-vehicle transmission line 3d. And between the primary station 40 and the secondary stations 41-43, transmission / reception of vehicle information is performed by a broadcast system.

  Next, with reference to FIG. 4, the operation | movement at the time of the joint of the train A and the train B is demonstrated.

  First, before the connection detection line 4 is connected, the secondary station 33 mounted on the train A is on standby as a secondary station of the train B. When the connection detection line 4 is connected, the primary station 40 mounted on the train B detects the connection with the train A (step S201), and the secondary station 33 detects the connection with the train B. (Step S202).

  The primary station 40 transmits a polling signal to the secondary station 33 (sequence SQ201), and the secondary station 33 transmits the polling signal from the primary station 40 within a predetermined period after the connection is detected. It is determined whether or not it has been received.

  When receiving the polling signal within the predetermined period, the secondary station 33 determines that the connection partner is the train B (step S203). Then, secondary station 33 returns a response signal indicating that the connection partner is determined to be train B (sequence SQ202). This response signal includes information on the number of both trains A.

  In addition, when the polling signal from the primary station 40 does not reach the secondary station 33 within a predetermined period (sequence SQ203), the secondary station 33 is configured such that the connection partner adopts the same transmission method as the train A. Judge that there is.

  In parallel with the operations of SQ201 and SQ202, the secondary station 33 transmits a polling signal to the primary station 40 (sequence SQ201 ′), and the primary station 40 is within a predetermined period after the connection is detected. Then, it is determined whether or not a polling signal from the secondary station 33 has been received.

  When the primary station 40 receives the polling signal within the predetermined period, the primary station 40 determines that the connection partner is the train A (step S203 '). Then, the primary station 40 returns a response signal indicating that the connection partner is determined to be the train A (sequence SQ202 '). This response signal includes information on the number of both trains B.

  When the polling signal from the secondary station 33 does not reach the primary station 40 within a predetermined period (sequence SQ203 ′), the primary station 40 uses a transmission system whose connection partner is the same as that of the train B. It is judged that.

  Here, in the combined train (train A + train B), the central station mounted on the leading vehicle 5a of the upstream train functions as the primary station of the entire train, and the second vehicles (5b-5d, 6a- In general, a terminal station mounted in 6d) functions as a secondary station. Therefore, the primary station 30 shown in FIG. 3 functions as a primary station in the entire organization.

  Next, with reference to FIG. 3, a specific example will be described of operations when the vehicle information is transmitted from the train A to the train B and when the vehicle information is transmitted from the train B to the train A.

  First, the case where vehicle information is transmitted from the primary station 30 of the train A to the secondary station 43 of the train B will be described. The vehicle information from the primary station 30 is sequentially transmitted by the bucket relay method and reaches the secondary station 33. The vehicle information that has reached the secondary station 33 is transmitted to the primary station 40 and the secondary stations 41 to 43 by the broadcast method together with the station number 01 that is the transmission source information.

And the secondary station 43 grasps | ascertains that it is the vehicle information from the primary station 30 with reference to transmission source information.

  Next, a case where vehicle information is transmitted from the secondary station 43 of the train B to the primary station 30 of the train A will be described. The secondary station 43 knows the station numbers of the primary station 30, the secondary station 31, the secondary station 32, and the secondary station 33. For example, the secondary station 43 is configured such that the primary station 30 is the primary station with the station number 11, the secondary station 31 is the secondary station with the station number 12, the secondary station 32 is the secondary station with the station number 13, and the secondary station 33 is grasped as the secondary station of the station number 14. Accordingly, the secondary station 43 transmits the vehicle information together with the station number 11 that is the destination information by the broadcast method. The same applies to the case where the vehicle information is transmitted from the secondary station 41, the secondary station 42, or the primary station 40 of the train B to the secondary station 33 of the train A. As described above, the primary station or the secondary station mounted on the train B performs information transmission by regarding the secondary station mounted on the combined vehicle 5a of the train A as a self-organized secondary station.

  In the secondary station 33 that has received the destination information and the vehicle information, the station number 11 is read as the station number 01 and the vehicle information is transmitted to the adjacent secondary station 32. And this vehicle information is sequentially transmitted to the secondary station 32-the secondary station 30 by a bucket relay system.

  According to the vehicle information monitoring apparatus according to the present embodiment, a part of the secondary station in the train B looks as if it is mounted on the coupled vehicle 5d of the train A. That is, the primary station 30 appears to be a secondary station with a station number 11 that can transmit vehicle information from the train B by the broadcast method. Similarly, the secondary station 31 appears as a secondary station with station number 12, the secondary station 32 appears as a secondary station with station number 13, and the secondary station 33 appears as a secondary station with station number 14.

  However, even in this case, the secondary station 33 functions as a secondary station in the train A between the primary station 30, the secondary station 31, and the secondary station 32 in the train A.

  As described above, when the train B is combined on the downside of the train A, the secondary station 33 mounted on the combined vehicle 5d of the train A is transmitted by the bucket relay method which is the first transmission method. The information from the secondary station 32 in the formation A is converted into the broadcast method information that is the second transmission method and transmitted to the primary station 40 or the secondary stations 41 to 43 of the other formation B. The information from the primary station 40 or the secondary stations 41 to 43 of the other organization B transmitted by the transmission method is converted into the information of the transmission method of the first transmission method and transmitted to the secondary station 32 of the own organization A. To do.

  Note that the predetermined period described above is a time set by paying attention to the difference between the transmission time in the bucket relay system and the transmission time in the broadcast system. To explain with a specific example, for example, when the train combined on the upstream side is train B, polling from train B (for example, polling from primary station 10) is the primary station of train A in the broadcast mode. Reach 20 On the other hand, when the train combined on the upstream side is another train of the same transmission method as that of the train A, the polling from this other train reaches the primary station 20 of the train A by the bucket relay method. . Therefore, the time until the polling from the other train on the upstream side reaches the primary station 20 of the train A varies depending on the type of the other train combined on the upstream side. The vehicle information monitoring apparatus according to the present embodiment considers such a situation, and determines whether polling has arrived within a predetermined period using the connection detection by the connection detection line 4 as a trigger. It is configured so that it can be determined whether or not the side organization is the organization that employs the same transmission method.

When train B is combined on the upstream side of train A and train A is further combined on the upstream side of train B, the combination of the entire formation after the combination is ABA. On the other hand, when train B is combined on the downside of train A and train A is further combined on the downside of train B, the combination of the entire formation after the combination is ABA. When train B is combined on the downside of train A and train B is combined on the upside of train A, the combination of the entire trains after the combination is BAB. Thus, the vehicle information monitoring apparatus and transmission method according to the present embodiment can also be applied to a combination of train A and train B.

  As described above, the vehicle information monitoring apparatus according to the present embodiment provides the second transmission different from the first transmission method for the second train B connected to the first train A. The vehicle information monitoring device for transmitting information between the primary station and the secondary station mounted on the second train set according to the system is mounted, and the primary station mounted on the combined vehicle of the first train set A Alternatively, the secondary station converts the information from the primary station or the secondary station in the self-organization A transmitted by the first transmission system into the information of the second transmission system to convert the primary station of the other organization B Alternatively, the information is transmitted to the secondary station, and the information from the primary station or the secondary station of the other transmission B transmitted by the second transmission method is converted into the information of the transmission method of the first transmission method and self-organized. Since the data was transmitted to the primary or secondary station of A, the software of the primary and secondary stations for train A Alone, not only in 併結 transmission method is the same organization, it is possible to transfer vehicle information even when 併結 the knitting B transmission scheme is different. Therefore, it is not necessary to add new hardware, and the vacant space of the vehicle can be effectively used for other purposes.

  The vehicle information monitoring device shown in the present embodiment shows an example of the content of the present invention, and can be combined with another known technique, and does not depart from the gist of the present invention. Of course, it is possible to change the configuration such as omitting a part of the range.

  As described above, the present invention can be applied to the vehicle information monitoring device and the transmission method of the vehicle information monitoring device, and in particular, between the trains without adding hardware even when the transmission method is different between the trains combined together. It is useful as an invention that enables transmission of information.
