DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rolling-stock set recognizing device for automatically recognizing a set-up state of a train.

[0002]

2. Description of the Related Art In a railway train, the status of each vehicle constituting the train is generally monitored centrally by a monitor device arranged in a leading vehicle or the like. For example, a monitor control device is installed in the leading vehicle at both ends, a monitor terminal device is installed in each intermediate vehicle, and these are connected by a network cable, and a monitor device with a monitor display setting device is installed in both leading vehicles. The status of each vehicle is monitored.

In this monitoring device, whether or not a door is normally closed is detected by a monitor terminal mounted on each vehicle, and the information is collected by a monitor control device of a leading vehicle through a network, and this is monitored. It is displayed on the display screen of the display setting device.

In order to centrally monitor the status of each vehicle using such a device, the order in which a plurality of vehicles forming the train are connected (arrangement order) and the connection of each vehicle are determined. Recognizing the direction is extremely important. That is, even if information with the ID number of the vehicle is transmitted from each vehicle, it is necessary to recognize which vehicle in the actual train corresponds to the vehicle with the ID number.

Conventionally, the order of vehicles is recognized by one of the following two methods. The first is a method in which nodes such as a monitor control device and a monitor terminal are cascaded, and nodes in the middle (monitor terminals) open and close network cables in order by a relay circuit to recognize the arrangement order. It is.

Second, a digital switch for setting a number is provided in a monitor terminal provided in each vehicle, and the digital switch of each vehicle is manually set in advance to a number corresponding to the actual vehicle arrangement order. Things.

The connection direction of the vehicle is provided, for example, by providing a monitor control device and a monitor terminal with a "direction switch". When the connection direction of the vehicle changes, the setting of this switch is manually changed. The change in the connection direction of the vehicle has been recognized on the monitor control device side.

Is inserted, there is a problem that the physical reliability of the network is reduced.

In the case of manually setting the order of vehicles and the direction of connection of vehicles to the switches, the number of steps for manually setting the switches is increased, and there is a possibility that an erroneous setting error may occur. Further, when the monitor terminal is replaced with a new one due to a failure, or when the vehicle itself is replaced with another one, there is a problem that each switch must be reset to an appropriate value.

The present invention has been made in view of such problems of the conventional technology, and automatically recognizes the order of vehicles and the connection direction of each vehicle without deteriorating the reliability of the network.

The monitor terminal (130) receives a confirmation signal to one of the first and second input / output terminals (133, 134) for the first time after receiving a vehicle number setting start command. A predetermined array number allocation request is transmitted to the monitor control device (110) through the communication line (140). That is, immediately after the vehicle number setting start command is transmitted, the relay units (135) of all the vehicles are in the non-relay state, and therefore, are initially mounted on the same leading vehicle as the monitor control device (110). Only the monitor terminal (130) receives the confirmation signal and sends out a sequence number assignment request.

At this time, the connection direction of the vehicle equipped with the own terminal during the formation is recognized in accordance with which input / output terminal the confirmation signal is input from. That is, since the confirmation signal is sent from the leading vehicle on which the monitor control device (110) is mounted, the first and second input / output terminals (13
3, 134), the connection direction of the own vehicle is identified based on which of the confirmation signals arrives.

Note that the confirmation signal may be a binary logic signal of a high level and a low level. For example, a predetermined voltage may be applied to the signal line (150) as the confirmation signal. In this case, a relay circuit (138) is provided in the relay section (135) of the monitor terminal (130), whereby the first input / output terminal (133) and the second input / output terminal (13) are provided.
4) It is configured to open and close the connection with. Also the first
Input circuit (136) on the side of the input / output terminal (133)
Is connected to the second input / output terminal (134) on the side of the second input circuit (1).
37) are arranged, and whether or not a predetermined voltage is applied to each input / output terminal is monitored.

As described above, a predetermined voltage (for example, DC
Voltage) is applied to output the confirmation signal, so that the circuit configuration can be simplified.

Further, a child device (110) is mounted on an end vehicle (end vehicle) opposite to the end vehicle on which the monitor control device (110) is mounted. The child device (110) communicates information through a communication line (140).
2) and an end portion (115) to which the end of the lead-in signal line (150) is connected. This terminal part (11
5) monitors whether a confirmation signal has been input from an adjacent vehicle, and the child communication unit (112) terminates a series of vehicle formation confirmation operations when the confirmation signal is input to the terminal unit (115). Is sent to the communication line (140). The monitor control device (110) and the monitor terminal device (130) end a series of rolling-stock set checking operations based on the reception of the vehicle number setting end command.

By adopting such a configuration, the formation confirmation operation can be surely ended at the time when the arrangement order of all vehicles has been confirmed. Note that the knitting confirmation operation may be ended by another method. For example, if the next array number allocation request is not received within a predetermined time after the previous array number has been transmitted, the monitor control unit (110) determines that the knitting confirmation operation has been completed, and It may be configured to notify each monitor terminal (130) of the fact. If the number of vehicles is already known, the formation confirmation operation may be terminated when the transmission of the array number matching the number of vehicles is completed.

The monitor control device (110) added with the function as the slave device (110) is mounted on both the leading vehicle and the trailing vehicle, and each of them is provided with the monitor control device (1).
If the function is switched between the function as 10) and the function as the child device (110), the same monitor control device (110) may be arranged in the leading vehicle and the trailing vehicle. Enables the vehicle to change its direction of travel freely.

Monitor control device 110 serving as a parent device
Receives the array number assignment request (step S40).
8) The array number is sent to the communication line 140 (step S409). The array number transmitted first is the same as that in step S
The value set at 407 is “1”. This array number is maintained until the allocation of the array number to the monitor terminals 130 of all vehicles is completed (step S410;
N) After transmission to one vehicle, it is incremented by "1" in preparation for transmission to the next vehicle (step S411).

The monitor terminal 130 that has transmitted the array number allocation request receives the array number sent from the monitor controller 110 of the parent apparatus via the communication line 140 (step S457). Here, the information transmitted through the communication line 140 can be received by all the monitor terminals 130, but only the monitor terminal 130 that has transmitted the array number allocation request and has not yet received the array number has The processing sequence is set to receive the array element number.

Monitor terminal device 130 that has received the array number
Closes its own relay circuit 138 (step S4).
58) Then, the monitor control device 1 which is a child device
When receiving the car number setting end instruction from the server 10, the connection direction and the array number (the order of arrangement in the train set) recognized earlier are registered in an internal memory (not shown) (step S461). The knitting state recognition operation ends.

By the above-described operation, first, the leading vehicle 1 directly connected to the master device and directly connected with the signal line 150 is connected.
0 of the monitor terminal 130 mounted on the first input / output terminal 1
A confirmation signal voltage is applied to 33. Therefore, first,
The monitor terminal device 130 of the leading vehicle 10 recognizes the connection direction and receives the assignment of the array number “1”.

Thereafter, the relay circuit 138 of the monitor terminal 130 mounted on the leading vehicle 10 is closed, and the first input of the monitor terminal 130 mounted on the first intermediate vehicle 20 which is the next vehicle is closed. The confirmation signal voltage is applied to the output terminal 133 for the first time. Then, the monitor terminal 130 mounted on the first intermediate vehicle 20 recognizes the connection direction, receives the assignment of the array number “2”, and closes the relay circuit 138 of the own device.

By repeating such operations sequentially, the monitor terminals 130 connected in series closest to the parent device are connected.
Recognition of the connection direction and array number is sequentially performed from the (mounted on the leading vehicle 10) to the monitor terminal 130 connected in series farthest from the parent device.

The monitor terminal 13 mounted on the last vehicle
0 closes its own relay circuit 138, the monitor controller 110 as a child device mounted on the trailing vehicle 50.
The confirmation signal voltage is applied to the input circuit 115 (step S420). The monitor terminal 130 as the child device that has confirmed the application of the confirmation signal voltage transmits a vehicle number setting end command to the monitor control device 110 as the parent device and the monitor terminal 130 of each vehicle through the communication line 140. .

Upon receiving the vehicle number setting end command, the monitor control device 110 as the parent device and the monitor terminal device 130 of each vehicle end a series of formation recognition operations (step S410; Y, S460).

Thus, the monitor terminal 1 of each vehicle
When the monitor terminal 30 recognizes the arrangement order during the formation and the connection direction to the parent device, each monitor terminal 130 monitors the node number assigned to its own device and information indicating the previously recognized arrangement order and connection direction. Transmit to the control device 110. As a result, the monitor control device 110 recognizes the formation state of the entire train, that is, the arrangement order and connection direction of all vehicles.

FIGS. 6 and 7 show the monitor control device 110.
3 shows various examples of screens displayed on the monitor display setting device 120 of FIG. In the header area 601 at the top of the screen,
The formation state of this train is simulated. That is, the node number received from each monitor terminal 130 is
It is arranged and displayed in accordance with the arrangement order sent with it. The connection direction is indicated by displaying numerical values on the first and second sides. Further, a horizontal triangle pattern 602 is additionally displayed on the leading vehicle serving as the parent device.

In the above-described embodiment, the confirmation signal voltage, which is a predetermined DC voltage, is applied to the pass-through signal line 150 as the confirmation signal. The value signal may be used as the confirmation signal. FIG. 8 shows an example of a monitor control device when a binary logic signal is used as a confirmation signal as described above.
FIGS. 9 and 10 show monitor terminals in the case where a binary logic signal is used as a confirmation signal.

In these examples, one lead-in signal line 1
50 is provided with a buffer element at each input / output so that a confirmation signal can be sent from any direction.

In the monitor control device 110a shown in FIG.
When operating as a parent device, the output buffer 701 is set to an operating state, and when transmitting a confirmation signal, the output signal level is set to high. In the parent device, input buffer 702 is set to a non-operation state. When used as a slave device, the input buffer 702 is set in the operating state, and the signal line 15 is routed from the adjacent monitor terminal.
It waits for a high-level confirmation signal to be input through 0. In the case of a child device, the output buffer 701
Is set to a non-operation state.

In the monitor terminal 130a shown in FIG.
In the state of waiting for the input of the confirmation signal (in the state shown in FIG. 3, the state in which the relay circuit 138 is open), the first
Input buffer 803 connected to the input / output end 133 of the
And the second input buffer 804 connected to the second input / output terminal 134 is brought into an operating state. The first output buffer 802 connected to the first input / output terminal 133 and the second output buffer 80 connected to the second input / output terminal 134
5 are both inactive.

The monitor terminal 130a monitors which of the first input buffer 803 and the second input buffer 804 receives the confirmation signal. After obtaining the connection direction and array number, deactivate the input buffer connected to the connection terminal on the opposite side of the input buffer that has confirmed the input of the confirmation signal, and also check the input buffer that has confirmed the input of the confirmation signal. The output buffer connected to the connection terminal on the opposite side is set to the operating state, and the confirmation signal is transmitted from the output buffer to the next stage.

For example, when the input of the confirmation signal is confirmed on the side of the first input buffer 803 connected to the first input / output terminal 133, the second input buffer 804 on the side of the second input / output terminal 134 is turned on. Set to the non-operating state, the second input / output terminal 1
The confirmation signal is transmitted from the second output buffer 805 on the 34 side to the next stage.

In the monitor terminal 130b shown in FIG. 10, when the output of the exclusive OR circuit 901 is at a high level, the confirmation signal is sent from one of the first input / output terminal 133 and the second input / output terminal 134. Is recognized, and in this state, the first input buffer 803 on the side of the first input / output terminal 133 outputs a confirmation signal depending on whether the output is at a high level or a low level. Input / output end 13
4 is determined. Note that the low level state may be set to the valid state of the confirmation signal.

In addition, in the embodiment, the leading vehicle having the monitor control device mounted thereon is disposed at both ends of the vehicle. However, in addition to both ends, the leading vehicle having the monitor control device mounted in the middle of formation is connected. It doesn't matter. In this case, the monitor control device 110 mounted on the leading vehicle arranged on the way
, And only the monitor terminal 130 may be used.

When two small trains are connected to each other to form one larger train, the arrangement order and connection direction of the vehicles in each of the small trains are recognized, and then the large train is recognized. The information such as the order of arrangement for each small composition may be transmitted to the monitor control device 110 serving as the parent apparatus of the parent composition to recognize the composition state of the large composition as a whole.

In the embodiment, the arrival of the confirmation signal to the monitor control device of the last vehicle has recognized that the formation confirmation operation has been completed for all vehicles.
Other methods may be used. For example, if the next array number allocation request is not received within a predetermined time since the last transmission of the array number, the monitor control device determines that the knitting confirmation operation has been completed, and notifies each monitor to that effect. It may be configured to notify the terminal device. Further, when the number of vehicles is known, the formation confirmation operation may be terminated when the transmission of the array number matching the number of vehicles is completed.
