Description

Description: TECHNICAL FIELD The present invention relates to a reversing machine conversion control method, and more particularly, to a railway for collectively controlling a plurality of different types of power vehicles having different reversing machine control methods of a power plant. The present invention relates to a method for controlling a reversing machine when driving a vehicle (hereinafter referred to as "cooperative driving").

[Prior Art] A technology for comprehensively controlling a vehicle group (hereinafter, referred to as "vehicle") having two or more power vehicles or a group of power vehicles of the same type is a technical magazine "Hitachi Review" Vol. 7) Known in PP7-12. In addition, general control is performed even between different vehicle types, for example, between an electric locomotive and electricity. However, it has been difficult to co-operate between powered vehicles having completely different performances and command systems, for example, an electric vehicle and a diesel vehicle.

[Problems to be Solved by the Invention]

The reason why it is difficult to cooperatively operate a power vehicle having completely different performances and command systems is that these vehicles are completely different not only in the power control but also in the method for controlling the turning-on of the reversing machine.
In an ordinary electric vehicle, even if the reverse handle of the main controller is operated forward or reverse, the reverse machine will not switch to forward or reverse unless the main handle is continuously operated to the powering position. . On the other hand, in a general diesel vehicle, when the reverse handle of the master controller is treated as forward or reverse, the reverse machine immediately switches to forward or reverse. Therefore, it has been impossible to control the electric vehicle and the diesel vehicle having different control methods from the master controller on the electric vehicle side or the master controller on the diesel vehicle side by the conversion and general control of the reversing machine of both vehicles.

If vehicles with different control methods for turning on the reversing machine can be operated in a coordinated manner, the convenience of transportation will be great, such as the ease of vehicle operation and train setting.

Therefore, an object of the present invention is to provide a reversing machine conversion control method that enables coordinated operation of vehicles having completely different reversing machine closing control methods.

[Means for solving the problem]

A feature of the present invention that achieves the above-mentioned object is that the power running circuit of the master controller is closed to close the closing circuit of the reversing machine and the power running of the master controller. When the closing circuit of the reversing machine is closed by a circuit independent of the circuit, and when general control of other vehicles that are not allowed to power until the completion of closing the reversing machine, the reversing machine of the other vehicle is controlled On the condition that the reversing machine of the one vehicle is controlled to be closed, a disconnecting switch is inserted in the middle of the power running circuit of the one vehicle, and the reversing machine of the one vehicle is completed. The reason is that the disconnector was closed.

Further, the completion of turning on the reversing machine of another vehicle is displayed or warned on one vehicle by a display or an audio device.

[Action]

After closing the power reversing circuit of the other vehicle by closing the power running circuit of the master controller of one of the vehicles, the reversing machine of one vehicle is turned on, the disconnecting switch is turned on, and the power running circuit is turned on. Since it is closed, it can be verified that the reverse gears of both vehicles have been completely inserted.

Further, since the completion of turning on the reversing machine of the other vehicle is connected to the display and the audio device of the one vehicle, the driver can easily know the completion of turning on the reversing machine of the other vehicle.

〔Example〕

Hereinafter, a train using the present invention as a control system in which the reversing machine closing circuit is closed by closing the power running of the master controller, and a circuit independent of the power running circuit of the master controller An example in which a reversing machine closing circuit is closed, and a liquid-type diesel vehicle (hereinafter referred to as “rail car”) that has a control system that does not allow power running until the completion of reversing machine closing is described. To do.

FIG. 1 is a system configuration diagram showing a configuration of a reversing machine conversion control system showing an embodiment of the present invention.

The electric train 100 supplies the electric power collected from the pantograph 1 to the variable voltage control device 3 by turning on the disconnector 2, and controls the voltage applied to the main motor 5 by the device 3 to rotate the wheels 6 to rotate the speed. Control is made. The reversing device 4 is provided between the variable voltage control device 3 and the main motor 5 to change the traveling direction of the vehicle. The railcar 200 transmits the rotational power of the internal combustion engine 21 to the wheels 24 via the reversing machine 22 and the liquid transmission 23. (The reverse gear 22 and the liquid transmission 23 may be arranged in reverse order.) The reverse rotation handle 7a of the main controller 7 does not start even if it is operated forward or backward. When the main handle 7b is subsequently notched, the signal converter 26 of the rail car 200 first sends a signal to the reversing machine control unit 28 to switch the reversing machine 22 to forward or reverse. When the reversing machine 22 completes the conversion (completion of closing control), the reversing machine checking unit 29 is closed. When the reversing device checking unit 29 is closed, the indicator 13 of the train 100 is displayed and the sound device 14 gives an alarm. In addition, the signal 7 of the master controller 7
The signals from a and 7b and the reversing device checking unit 29 give a forward or reverse conversion signal from the reversing device control unit 10 to the reversing device 4, and the reversing device 4 switches to forward or backward. When the conversion is completed, the disconnector 2 is turned on by the reverser interlocking unit 11 via the disconnector controller 8. Therefore, the disconnector 2 can be closed only after the reversing machine 22 of the railcar 200 has been switched. When the disconnector 2 is closed, the disconnector interlocking part 12 is also closed. The voltage control unit 9 of the voltage control device 3 is controlled corresponding to the notch of the master controller 7, and controls the voltage applied to the main motor 5.
On the other hand, the signal from the reversing device checking section 29 of the reversing device 22 and the master controller 7
When the signals 7a, 7b of are input to the signal converter 26, the fuel control unit 2
Reference numeral 7 controls the fuel injection amount of the internal combustion engine 21 in response to the notch of the main handle 7b of the main controller 7 to control the rotational speed of the internal combustion engine 21. The liquid transmission 23 is switched by the transmission control unit 30 to neutral, speed change, or direct connection.

In this way, the main controller 7 of the train 100 is treated as a forward or backward notch, and after checking that the reversing machine 22 of the railcar 200 has been closed and the conversion has been completed completely,
After 100 reversing machines 4 are closed and the complete conversion is checked, the disconnecting switch 2 can be closed.

As in this embodiment, it is possible to improve the operability of driving by notifying the completion of conversion of the reversing device by means of the display and the audio device.

FIG. 2 is a system configuration diagram showing a configuration of a reversing machine conversion system showing another embodiment of the present invention.

In the reference numerals of FIG. 2, the same reference numerals as those shown in FIG.
The same as or equivalent to those shown in the figure are shown.

When the reversing handle 25a of the master controller 25 of the rail car 200 is operated forward or backward, first, the reversing machine control unit 28 closes the circuit of the reversing machine 22 forward or backward, and the reversing machine 22
Turns into forward or reverse. When the conversion is completely completed, the reversing device checking unit 29 is closed. When the main handle 25b of the master controller 25 is continuously treated as a notch, the reverse signal is sent from the reversing machine control unit 10 to the reversing machine 4 by the output signal of the signal converter 26 and the signal of the reversing machine checking unit 29. Is entered.
When the reverse gear 4 switches to forward or reverse, the reverse gear interlocking part 11
Is closed, and the disconnector 2 is turned on via the disconnector controller 8. When the disconnector 2 is closed, the disconnector interlocking part 12 is also closed. The voltage control unit 9 of the voltage control device 3 is controlled corresponding to the notch of the master controller 25 to control the voltage applied to the main motor 5. Signals 25a, 25 from the reversing device inspection unit 11 and the master controller 25
The control signal corresponding to the notch of the master controller 25 is output from the signal converter 26 to the fuel controller 27 by the input signal of b.

In this way, even when a driving operation is performed from the railcar 200, first, it is checked that the reversing machine 22 of the railcar 200 has been completely converted, and then the reversing machine 4 of the train 100 is converted to completely convert it. By turning on the disconnecting switch 2 after checking the above, both reversing machines of different systems can be completely converted.

FIG. 3 is a circuit configuration diagram of a main part of the reversing machine conversion control method in the embodiment of the present invention shown in FIG.

When the reversing handle 7a of the main controller 7 of the train 100 is operated from the off position to the front (forward) position and the main handle 7b is continuously operated from the off position to the power running notch position (1 to 5),
When the vehicle is stopped (about 3 Km / h or less), the reversing machine 22 of the rail car 200 is switched to the forward side by a forward command applied via the speed detector 26-3 of the signal converter 26 which is closed. When the reversing machine 22 is completely switched to the forward side, the circuit of the reversing machine checking section 29 is closed, and the control section 10a in the reversing machine control section 10 of the electric train 100 is operated by the power source supplied from the railcar 200 side and its interlocking 1
Since 0b is closed, the reversing machine 4 of the train 100 is switched to the forward side. When the reversing machine 4 completes the conversion to the forward side, the reversing machine interlocking part 11 is closed. So disconnector controller 8 and fuel controller
27 is controlled.

Once the forward command of the master controller 7 enters the signal converter 26, the forward signal converter 26-1 changes from the power supply to the backward signal converter 26.
-2 contact 26-2b → Forward signal converter 26-1 contact 26-
1c → Self-held by the circuit of the coil 26-1a of the forward signal converter 26-1. This self-holding is not released even if the main handle 7b of the master controller 7 is set to the off position or the reverse rotation handle 7a is set to the off position. Reversing handle 7a
To the reverse position and then move the main handle 7b to the notch position (1 to
Proceeding to 5), the backward signal converter 26-
Since the second coil 26-2a is excited and the contact 26-2b is opened, the coil 26-1a of the forward signal converter 26-1 is opened.
Is released and released from self-holding. This time, power → 26
-1b → 26-2c → 26-2a circuit for backward signal converter
26-2 is held on the reverse side.

In this way, once a reverse rotation command is input in forward or reverse, the reverse rotation command is held by the signal converter 26 until a reverse rotation command in the opposite direction is input.

The speed detector 26-3 in the signal converter 26 closes the contact when the vehicle speed is stopped (for example, 3 Km / h or less), and opens the contact when the vehicle is running (for example, 3 Km / h or more). It is impossible to switch the reverse gear while the vehicle is running.

In this embodiment, the conversion prevention circuit and the conversion holding circuit during traveling prevent unnecessary conversion and ensure the reliability of conversion.

〔The invention's effect〕

According to the present invention, trains and railcars, which are completely different in control system from each other, are connected to each other so as to convert both reverse gears from either the main controller of the train cab or the main controller of the railcar cab. It can be done reliably. Also,
Since it is possible to turn on the disconnecting switch after checking that the conversion of the reversing machine is completely completed, the incomplete conversion state of the reversing machine prevents powering and prevents the failure of the reversing machine.
