Description

Train connection / disconnection monitoring device

The present invention relates to a train connection / separation device, and more particularly, to a train connection / separation device used when connecting or disconnecting trains, such as Shinkansen, Japan, in a railway yard.

In recent years, the Shinkansen bullet train has been opened, allowing the Shinkansen train to make regular round trips between Tokyo and Akida. In this case, the connecting or disconnecting work of the train is performed in Fukushima. When this connect / disconnect operation is performed, the inspector checks the prescribed inspection points of these operations.

The inspector uses a monitoring device to verify that the connection or disconnection is performed reliably. Figure 3 is a block diagram showing the structure of a conventional train connection / disconnection monitoring device. Here, when two trains are connected or separated, the main vehicle with the cab has the control and the main role train is called the "main train" if the master relationship is established between the two trains. On the other hand, a train with a driver's cab but no control and a subordinate role is called a "train."

The main train consists of vehicles 1 to N. Vehicle 1 is the front vehicle with a cab and control. Vehicle N is the last vehicle with a cab and is connected to the opposite end of the front vehicle (car No. 1). Similarly, longitudinal trains consist of N + 1 to N + M vehicles. The N + 1 vehicle is the front vehicle with a cab but no control. The N + M vehicle is the last vehicle with a cab and is connected to the opposite end of the front vehicle (N + 1 vehicle). The two trains connect or disconnect the coupler (1) installed in the N vehicle, the last vehicle of the main train, and the coupler (2) installed in the N + 1 vehicle, the front vehicle of the slave train.

Each of the vehicles of Nos. 1 to N + M is provided with a terminal monitor 3. In addition, each of vehicles No. 1, N, N + 1 and N + M having a cab is provided with a central monitoring device 4 and a monitoring display device 5 in addition to the terminal monitor 3. The terminal monitor 3 collects information such as driving status of the device installed in each vehicle and transmits it to the central monitoring device 4 of the first vehicle. Here, the terminal monitor 3 of each vehicle and the central monitoring unit 4 of vehicle 1 are connected via the transmission line 6.

In addition, the control authority changeover switch (not shown) is provided in each central monitoring apparatus 4 of No. 1, N, N + 1, and N + M vehicles. Only the control authority changeover switch of the central monitoring unit 4 of the No. 1 vehicle is set to the ON position, and the control authority changeover switches of the N, N + 1 and N + M vehicles are set to the OFF position, respectively. Various signals are exchanged between the central monitoring unit 4 of the first vehicle and the terminal monitor 3 of each vehicle by polling transmission.

In addition, two connection detection signal lines 7a and 7b are connected between the connector 1 and the terminal monitor 3 of the N-number vehicle. When the connection operation is made, the ON information of the connection detection signal is transmitted to the terminal monitor 3 of the N-number vehicle, and also to the central monitoring device 4 of the No. 1 vehicle. In this conventional example, there are two kinds of vehicles in the kind of vertical train, and thus the number of connection detection signal lines is two lines. For example, the connection detection signal passes through the connection detection signal line 7a when the type of the vehicle of the slave train is the system A, and the connection detection signal is the connection detection signal line when the type of the vehicle of the slave train is the system B. Pass 7b). As described above, the connection detection signal passes through one of the connection detection signal lines 7a and 7b and is transmitted from the connector 1 to the terminal monitor 3 of the N-number vehicle.

Next, the operation of the conventional monitoring device configured as described above will be described taking the connection operation as an example. When the train is connected to the main train, the ON information of the connection detection signal from the connector 1 is transmitted through one of the connection detection signal lines 7a or 7b to the terminal monitor 3 of the N-number vehicle. Then, the inspector rides in the cab of the first vehicle and operates the monitoring display device 5. When the connection detection signal is transmitted via the connection detection signal line 7a, the terminal monitor 3 of the N-number vehicle notifies the central monitoring device 4 of the No. 1 vehicle that the vehicle type of the train is system A. Similarly, when the connection detection signal is transmitted through the connection detection signal line 7b, the terminal monitor 3 of the N-number vehicle notifies the central monitoring device 4 of the No. 1 vehicle that the vehicle type of the slave train is system B. do.

Based on this information from the terminal monitor 3 of the vehicle N, the central monitoring device 4 of the vehicle 1 displays the vehicle type of the train on the monitoring display device 5. The inspector can confirm that the train of System A or System B is connected to the main train while watching the screen of the monitoring display device 5.

The linking operation is performed as described above. In the case of the disconnection operation, the central monitoring unit 4 can confirm that the slave train of the system A or the system B is disconnected when the connection detection signal transmitted from the terminal monitor 3 of the N-number vehicle is changed to OFF information. have.

In recent years, the number of vehicle types is gradually increasing due to the existence of many vehicle manufacturers and the development of new vehicle types with the development of train manufacturing technology. Therefore, in order for the inspector to check the type of the vehicle while viewing the display screen of the monitoring display device 5, it is necessary to additionally install the connection detection signal line connected to the terminal monitor 3 of the N-number vehicle as the number of vehicle types. There is.

However, the additional installation of the connection detection signal lines equal to the number of vehicle types is not really easy. The wiring work and the check of the connection detection signal line should be carried out at a fixed place such as a vehicle compartment. However, even if the vehicle currently in operation stops temporarily, the operation of the train according to the timetable greatly occurs. Further, even if the connection detection signal lines are increased with a great deal of effort, if the number of vehicle types further increases afterwards, it is necessary to increase the number of the connection detection signal lines by that much. In recent years, the number of types of vehicles has tended to increase further, and therefore, it has become difficult to increase the connection detection signal line with the increase of the number of types of vehicles.

Accordingly, one object of the present invention is to provide a train connection / separation monitoring device that does not need to increase the connection detection signal line even if the number of vehicle types increases, thereby stopping the train for wiring work of the connection detection signal line, and so on. It is to avoid the disruption of trains on the streets.

The above and other objects of the present invention provide a train connection / separation monitoring device for monitoring the connection and disconnection operation between the last vehicle of the main train and the front vehicle of the train of the train consisting of the main train and the sub train. This can be achieved by. The train connection / separation monitoring device comprises a code signal input circuit for inputting a vehicle type code signal for each vehicle number set in advance through a transmission line, and a connection detection signal and code signal input circuit from the last vehicle of the main train. Receiving whether the connection or disconnection operation is properly performed based on the connection detection signal and the vehicle type code signal for each vehicle number by receiving the vehicle type code signal for each vehicle number of the vehicle, and determining the vehicle type of the train. It is composed of a central monitoring device including a vehicle type determination circuit.

DETAILED DESCRIPTION OF THE EMBODIMENTS To assist in understanding the present invention and the many advantages associated with it, it is described in detail below with reference to the accompanying drawings.

(Example)

Best Mode for Carrying Out the Invention Embodiments of the present invention will be described below with reference to the drawings, in which like parts are indicated by like reference numerals.

1 is a block diagram showing the structure of the main part of the train connection / disconnection monitoring apparatus according to an embodiment of the present invention.

In FIG. 1, the central monitoring device 4 of the vehicle 1 has a code signal input circuit 8, an operation / vehicle determination circuit 9 and a display control circuit 10. As shown in FIG. No. 1 to N and N0. The vehicle code signal for each vehicle number from each terminal monitor 3 of N + 1 to N + M vehicles is input to the code signal input circuit 8. The vehicle type code signal for each vehicle number is a signal indicating a unique number assigned to each vehicle, and is a 3-bit or 4-bit information amount in combination of a "0" signal and a "1" signal. The vehicle type code signal for each vehicle number can be easily generated by a switch provided in each terminal monitor 3 of each vehicle. This switch is constituted, for example, by a preset dip switch.

The terminal monitor 3 and the connector 1 of the vehicle N are connected by only one connection detection signal line 7. The connection detection signal for notifying the connection between the connector 1 and the connector 2 of another train is transmitted to the terminal monitor 3 of the N-number vehicle. This connection detection signal is also transmitted from the terminal monitor 3 to the operation / vehicle determination circuit 9 of the central monitoring unit 4 of the first vehicle. The operation / vehicle determination circuit 9 receives the connection detection signal as digital information from the terminal monitor 3 of the N-number vehicle, and receives the vehicle type code signal for each vehicle number from the code signal input circuit 8.

The operation / vehicle determination circuit 9 properly connects the trains based on the connection detection signal from the terminal monitor 3 of the N-number vehicle and the vehicle type code signal for each vehicle number from the code signal input circuit 8. And the type of the vehicle are determined, and the determination result is output to the display control circuit 10. The display control circuit 10 displays this determination result on the screen of the monitoring display device 5.

Next, the operation of the monitoring apparatus shown in FIG. 1 will be described. After connecting the train to the main train, the inspector who boarded the cab of the first vehicle turns on the central monitoring unit 4. The central monitoring unit 4 initiates polling transmission for each terminal monitor 3 of each vehicle. The code signal input circuit 8 inputs a vehicle type code signal for each vehicle number from each vehicle, and outputs it to the operation / vehicle determination circuit 9. The operation / vehicle determination circuit 9 receives the vehicle type code signal for each vehicle number from the code signal input circuit 8 and receives the connection detection signal as digital information from the terminal monitor 3 of the N-number vehicle. .

The operation / vehicle determination circuit 9 only knows that a certain train is connected only by the connection detection signal from the terminal monitor 3 of the N-number vehicle, but the vehicle type by vehicle number from the code signal input circuit 8. The vehicle type of the trains connected by the code signal can be specified. Here, one vehicle type code signal based on the input of all vehicle type code signals of N + 1 to N + M vehicles or of a vehicle having a designated number (for example, N + 1 vehicle having connector 2 installed). Based on the bay, the vehicle type of the train can be specified. However, the designation of the vehicle type of the train based on the input of all vehicle type code signals can increase the load of the CPU constituting the operation / vehicle determination circuit 9 and thereby reduce the processing speed. Due to the quantum leap in computer technology, this increase in load is not a problem at all when the recent CPU is used for the operation / vehicle determination circuit 9. However, a fairly old CPU is used in the operation / vehicle determination circuit 9, which may adversely affect the processing speed due to the load increase amount. On the other hand, when the vehicle type of a train is designated based on only one type of vehicle type code signal, the type of vehicle is designated when a failure occurs in the N + 1 vehicle, that is, the transmission device or transmission line around the vehicle of the designated number. It becomes impossible to do. Therefore, in the present embodiment, the train connection is performed so that the vehicle type of the train can be specified by at least one of two kinds of vehicle type code signals of the N + 1 vehicle having the cab and the connector 2 and the N + M vehicle having the cab. Configure a separate monitoring device.

As described above, the display control circuit 10 monitors the contents of the determination result regarding whether the connection operation with the sub train by the operation / vehicle determination circuit 9 is properly performed and the type of the vehicle of the sub train. ). The inspector checks this display screen to confirm whether or not the connection work is completed, and the train that has completed the connection work is turned over to the operator in charge.

Fig. 2 is an explanatory diagram showing the display contents of the monitoring display device 5 in a table form corresponding to the operation state of the operation / vehicle determination circuit 9, which is checked by the inspector. As shown in this figure, when the operation / vehicle determination circuit 9 inputs the connection detection signal from the terminal monitor 3 of the N-number vehicle, the character " in this connection " is displayed. Subsequently, the operation / vehicle determination circuit 9 receives the vehicle type code signal of either the N + 1 or N + M vehicle by polling transmission between the central monitoring unit 4 and the terminal monitor 3 of each vehicle. Is displayed, the character "System A is connecting" is displayed when the train is System A, or the character "System B is connecting" is displayed when the train is System B.

However, if the operation / vehicle determination circuit 9 inputs only the connection detection signal and does not input the vehicle type code signal of either the N + 1 or N + M vehicles, only the character of "this connection" is initialized. It is displayed for 5 seconds, after which the character " System A is connecting " is displayed, and also a default for notifying that the transmission system is abnormal. In this case, it is needless to say that the text "System A is connecting" does not indicate the actual vehicle type of the train.

When this default is displayed, the inspector switches the screen of the monitoring display device 5 to another channel and examines the above contents in detail. However, while the default is being displayed, anomalies in transmission may be recovered for some reason. In this case, the default display disappears and only the letters "System A are connecting"; when the slave train is System A, only the letters "System B are connecting" are displayed when the slave train is System B. In addition, after inputting the connection detection signal, information related to the type of vehicle suitably designated initially is stored in the operation / vehicle determination circuit 9 until the input of the connection detection signal is subsequently turned off.

According to the train connection / separation monitoring device according to the embodiment of the present invention having the structure shown in FIG. 1, the connection detection signal line 7 connected between the terminal monitor 3 and the connector 1 of the N-car is one line. It is only. Although the number of vehicle types increases, it is only necessary to register the vehicle type code signal for each vehicle number in order for each new vehicle on the terminal monitor 3 in each of each new vehicle. Therefore, there is no need to install additional connection detection signal lines as before. In addition, since the default display is predetermined, it is possible to display only that the connection operation has been executed correctly, even if some abnormality occurs in the transmission system for some reason. When the transmission system recovers from the abnormal state, the display can be returned from the default display to the normal display.

In addition, although the embodiment of the present invention has been described taking the train connection operation as an example, the disconnect operation is almost the same as the connection operation. That is, in Fig. 1, when performing the disconnect operation, if the connection detection signal output from the terminal monitor 3 of the N-number vehicle to the vehicle operation / type determination circuit 9 is turned off, this functions as a "separation detection signal". . Since other operations are the same as described above, the description thereof is omitted.

As described above, according to the present invention, even if the number of vehicle types increases, it is possible to provide a connection / disconnection monitoring device for a train that does not need to increase the connection detection signal line. Therefore, it is possible to avoid the disruption of the train operation according to the timetable by stopping the train due to wiring work of the connection detection signal line.

Many modifications and variations of the present invention are possible in light of the above teachings. Therefore, within the scope of the claims of the present invention, implementations other than those described herein above are included in the present invention.
