Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interface device between railway vehicles for enabling cooperative operation of different types of railway vehicles using different control signals.

[0002]

2. Description of the Related Art When a plurality of railway vehicles are connected and operated, the operation contents of a crew member using a mass control switch or the like are transmitted in parallel to equipment mounted on each railway vehicle via a lead line (control line). .

FIG. 12 is a block diagram showing an example of the configuration of a conventional railway vehicle connected.

Each of the railway vehicles 1a to 1c is generally provided with various control devices 2 such as a cooling / heating device, a drive motor, a door opening / closing device, an electric light device, etc., but the description is simplified in FIG. Therefore, only the cooling and heating device is illustrated.

[0005] The same type of control equipment 2 for each of the railway vehicles 1a to 1c
Are connected to the same lead wire 3, and further to this lead wire 3, a driver's cab 4 that issues a control signal to the same type of control device 2 is connected.

In the cab 4, a control signal power supply 4a is connected to one end of a command switch 5, and the other end of the command switch 4b is connected to a lead wire 3.

[0007] The operation by the crew is performed by a signal generated by applying pressure to the wire 4 by connecting the command switch 4b.
The control devices 2 for each c are notified in parallel, and each control device 2 operates based on this control signal to perform cooperative operation.

The same applies to other control devices other than the control device 2. The same type of control device and a command switch for controlling this control device are connected to a predetermined lead wire, and control signals are notified in parallel.

[0009]

As shown in FIG. 12, when the conventional railway vehicles 1a to 1c are connected,
Control devices 2 of the same type are connected by a lead line 3, and a control signal for the control device 2 is notified via the lead line 3. That is, this conventional method of connecting railway vehicles 1a to 1c is based on the premise that the connected railway vehicles 1a to 1c are of the same vehicle type and that the control signals handled by the same type of control device 2 are of the same type.

When the railway vehicles 1a to 1c to be connected are of different types, the meanings of the signals are different, so that it is necessary to convert (read) the control signals.

As an example, consider the case where the ON signal in the cooling device of the main railway vehicle is 3V and the ON signal in the cooling device of the subordinate railway vehicle is 10V. in this case,
In order to notify an ON signal from a main railway vehicle to a subordinate railway vehicle via a lead wire, it is necessary to convert a 3V signal to 10V.

Further, if the types of railway vehicles to be connected are different, the number of lead wires used for the same type of control equipment may be different, and in this case, it is necessary to absorb the difference between the vehicles.

As an example, the cooling system of the main rolling stock can realize strong cooling and weak cooling, and a total of two lines, a strong cooling ON lead line and a weak cooling ON lead line, are connected. It is assumed that a cooling device of a railway vehicle of a system is connected to a cooling lead line that transmits only a cooling ON signal. In this case, for example, when an ON signal is transmitted to at least one of the strong cooling ON lead line or the weak cooling ON lead line in the main railway vehicle, the cooling ON signal is transmitted to the cooling lead line of the slave railway vehicle. A conversion is needed to be transmitted.

In order to convert the meaning of such control signals and the number of lead wires, it is possible to use a circuit that inputs a control signal of one railway vehicle and outputs it as a control signal of the other railway vehicle. Conceivable.

However, when a circuit for simply inputting a control signal for a main railway vehicle and outputting it as a control signal for a subordinate railway vehicle is used, the control signal output from the circuit depends on the connection state of the railway vehicles. May be seen on the input side, causing a loop. As a result, a circuit for the control signal is formed, and the transmission of the command is hindered.

As an example, consider an apparatus that converts an ON signal of a main railway vehicle into an ON signal of a slave railway vehicle and outputs the ON signal. In such a device, when the converted ON signal wraps around and appears on the input side, the OFR is sent from the main railway vehicle to the OF rail.
Even if the F signal is input, there arises a problem that the device always outputs the ON signal to the subordinate railway vehicle due to the converted ON signal that has wrapped around.

As described above, conventionally, it is difficult and time-consuming to transmit a control signal, so that there has been no opportunity to connect and operate a railway vehicle between different types of vehicles.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described circumstances, and is intended to easily and satisfactorily convert (reread) control signals required when connecting different types of railway vehicles. It is intended to provide an interface device.

[0019]

The gist of the present invention is to introduce an insulating circuit in a portion for converting a control signal, thereby to convert a control signal input from one railway vehicle and a converted signal output to another railway vehicle. This is to separate the control signal from the control signal, thereby realizing the cooperative operation of the railway vehicle between different types of vehicles.

Hereinafter, specific measures taken to realize the present invention will be described.

The present invention is an inter-railway vehicle interface device for transferring control signals between a first railway vehicle and a second railway vehicle having inconsistent control signal contents.

The inter-railway vehicle interface according to the first invention converts the content of the control signal input from the first railroad vehicle into a second railroad vehicle control signal using an insulating circuit, and converts the content into a second railroad vehicle control signal. Output to railway vehicles.

As the insulating circuit, for example, a relay circuit or a photocoupler can be used. In addition, a means for generating a new signal without directly using an electric signal, such as a processing circuit such as a CPU, can be applied.

As described above, the control signal passed between the different types of railway vehicles is converted while preventing the electrical interaction between both ends of the device by using the insulating circuit.
It is possible to prevent the output control signal from going around to the input side.

Therefore, it is possible to easily and satisfactorily read the control signals required for connecting different types of railway vehicles.

An interface device according to a second aspect of the present invention is a control signal converting means for converting the content of the control signal input from the first railway vehicle into the control signal for the second railway vehicle using an insulating circuit, When a command signal to follow a control signal from the first railcar is input, a control signal for the second railcar obtained by the control signal conversion means is output to the second railcar, and the command signal is input. If not, an output determination unit is provided that disables output of the control signal for the second railway vehicle obtained by the control signal conversion unit to the second railway vehicle.

In the inter-railway vehicle interface device according to the second aspect of the present invention, since the insulating circuit is used, it is possible to prevent the occurrence of a round circuit.

When a command signal is input, a control signal is transmitted to a different type of railway vehicle.

[0030] Therefore, different types of railway vehicles can be easily and satisfactorily connected, and the railway vehicles can be freely combined and operated, so that excellent service can be provided. For example, it is possible to reduce the cost by making it possible to use a newly introduced model and an old model together.

However, when the control signal is not input from one railway vehicle, the control signal is transmitted from the other railway vehicle. When a control signal is input, the control signal from the other railway vehicle is converted and transmitted to one railway vehicle.

Therefore, even when the trains are connected between different types of railway vehicles, if one of the railway vehicles is operated as a main system and no control signal is generated by this main system, it is required. Thus, the operation can be performed by applying the slave control signal.

Therefore, different types of railway vehicles can be easily and satisfactorily connected, and excellent service can be provided.

More specifically, this photocoupler 2
In 9, when the control signal is received, the signal “H” from the power supply 31 is provided to the emitter from the connector of the phototransistor 29 b, and as a result, the signal “L” is provided to the tristate buffer 32 from the power supply 31. That is, “H” obtained by inverting the signal “L” is received by the tri-state buffer 32. On the other hand, when the control signal is not received, the signal “H” from the power supply 31 is provided not to the phototransistor 29b but to the tri-state buffer 32, and is inverted and received as “L” by the tri-state buffer 32.

When the determination signal “L” is provided from the output determination unit 25b to the power supply terminal, the tristate buffer 32 receives the inverted “H” of the determination signal “L”,

N.

In this case, since the command signal is not provided to the photocoupler 33 in the output determination section 25b of the railway vehicle interface device 25, the signal "H" from the determination power supply 35 is not supplied to the photocoupler 33 but to the control signal conversion. The signal is received by the power supply terminal of the tri-state buffer 32 in the unit 25a.

In the tri-state buffer 32, the signal "H" from the determination power supply 35 of the output determination section 25b is inverted and received as "L" at the power supply terminal, so that the tri-state buffer 32 is cut off.

As a result, the main command switch 6b is set to O
Even if it is set to N, the control signal is not output from the inter-railway vehicle interface device 25, so that the converted control signal is not provided to the slave control device 7.

Therefore, the command switch 24b is turned off.
In this case, the control signal from the main cab 24 is transmitted only to the main control device 11.

Here, when it is desired to operate both the main railway vehicle 23a and the subordinate railway vehicle 23b collectively on the main cab 24, the main system command switch 24b is turned ON.

Then, the command signal “H” is provided to the photocoupler 33 in the output determination unit 25b of the railway vehicle-to-vehicle interface device 25, so that the control signal conversion unit 25
The signal "L" will be provided to the power supply terminal of the tri-state buffer 32 in a.

In the tri-state buffer 32, the signal "L" from the determination power supply 35 of the output determination section 25b is inverted and is received as "H" at the power supply terminal, so that the tri-state buffer 32 is in the connected state.

(Third Embodiment) In this embodiment, a control signal of a main railway vehicle is transmitted to a slave railway vehicle, and no control signal is generated in the main railway vehicle. A description will be given of a railcar-to-railcar interface device that transmits a control signal of a subordinate railcar to a main railcar.

FIG. 6 is a circuit block diagram schematically showing an interface apparatus between railway vehicles according to the present embodiment, and the same parts as those in FIG. 1 or FIG. Or a brief description, and here only the different parts will be described in detail.

The cab 6 of the subordinate railway vehicle 5b is connected to the subordinate control device 7 and the input / output terminal 44 of the inter-railroad vehicle interface device 43 provided in the main railway vehicle 42a.

The cab 10 of the main railway vehicle 42a is connected to the input terminal 45 of the railway vehicle interface device 43.

When a control signal is input from the cab 10 of the main system, the interface device 43 between the railway vehicles according to the present embodiment converts the control signal of the main system into the control device 11 of the main system and the slave system. When the control signal is transmitted to the control device 7 but the control signal is not input from the cab 10 of the main system but is input from the cab 6 of the sub system, the control signal of the sub system is also transmitted to the control device 11 of the main system. Perform the operation of transmitting.

To this end, the railway vehicle-to-railway interface device 43 is connected at an input end 45 to the main cab 10 and at an output end 46 to the main control device 11. The output terminal 44 is connected to the subordinate cab 6 and the control device 7.

The railway vehicle-to-railway interface device 43
Switches mainly according to the presence or absence of a control signal from the main system, a power supply 14 for outputting a control signal of the main system as a control signal of the sub system, a power supply 47 for outputting the same control signal as the main system. A relay circuit 48 and a control signal converter 25a for receiving a control signal from a slave through the input / output terminal 44
And an output determination unit 25b.

The relay circuit 48 operates as an insulation circuit for control signals from the main cab 10, and includes a coil 48a, one end of which is connected to the other end of the command switch 10b and the other end of which is grounded. It comprises a signal conversion contact 48b, an output determination contact 48c, and a self-control signal output contact 48d.

When the command switch 10b is closed and a control signal is input, the coil 48a of the relay circuit 48 is excited and the contacts 48b to 48d are switched.

The control signal conversion contact 48b has one end connected to the power supply 14 for generating a signal similar to the slave control signal, and the other end connected via the input / output end 44 of the railroad vehicle interface device 43. A normally open contact connected to the control device 7 and the cab 6 of the system.

The control signal conversion contact 48b is connected when a main control signal is input and the coil 48a is excited, and the control signal of the sub system indicating the same contents as the input main system control signal is inputted. Is output to the slave control device 7 via the input / output terminal 44.

The output determination contact 48c has one end connected to the main control signal generating power supply 10a and the other end connected to the photodiode 33a of the photocoupler 33 provided in the output determination unit 25b in the railway vehicle interface device 43. Normally closed contact connected to the input terminal.

When the main control signal is input and the coil 48a is excited, the output determination contact 48c is turned off, and the output determination section 25b stops supplying the signal to the photodiode 33a. As a result, the output control unit 25b rejects the converted control signal output from the control signal conversion unit 25a.

One end of the self-control signal output contact 48d is connected to the power supply 47 for transmitting a signal similar to the control signal of the main system, and the other end is connected to the railroad-vehicle interface device 43.
Are normally open contacts that are connected to the main control device 11 via the output end 46.

The self-control signal output contact 48d is connected when a main control signal is input and the coil 48a is excited, and a control signal from the power supply 47 similar to the input control signal is transmitted to the main control signal. The information is transmitted to the device 11.

The control signal converter inputs the slave control signal to the input / output terminal 44 of the inter-railway vehicle interface device 43 and uses the photocoupler 29 which is an insulating circuit to input the slave control signal. To the tri-state buffer 32
To convert the signal into a main control signal. Then, when the output determination unit 25b permits the output, the converted control signal of the main system is output via the output terminal 46.

The output judging section 25b has an output judging contact 48c.
, Ie, when the main control signal is input to the inter-railway vehicle interface device 43, the tri-state buffer 3 of the control signal converter 25a
2 to output a signal “H” for disconnecting. When no signal is received from the output determination contact 48c, that is, when the main control signal is not input to the railroad-vehicle interface device 43, the control signal converter 25a
To output a signal "L" for connecting the tri-state buffer 32 to the connected state.

The signal "H" output from the output determination unit 25b is inverted to "L" to turn off the tristate buffer 32 and disable the output of the converted control signal. On the other hand, the signal "L" output from the output determination unit 25b becomes the inverted "H", and sets the tri-state buffer 32 to the connected state so that the converted control signal can be output.

The operation when the railway vehicles 42a and 5b are connected using the railway vehicle interface device 43 having the above configuration will be described below.

First, the command switch 1 of the main cab 10
When 0b is turned on and a main control signal is input from the input terminal 45 of the railway vehicle interface device 43, the control signal conversion contact 48b and the self-control signal output contact 48d of the relay circuit 48 are connected, and the output is determined. The contact 48c is opened.

Then, a subordinate control signal having the same content as the input main control signal is supplied from the power supply 14 to the subordinate control device 7 via the input / output terminal 44 of the inter-railway vehicle interface device 43.

Similarly, the same control signal as the input main control signal is supplied from the power supply 47 to the main control device 11 via the output terminal 46 of the inter-railcar interface device 43.

Since the output slave control signal and master control signal are converted from the input master control signal using the relay circuit 48 which is an insulating circuit, no roundabout circuit is generated. .

In this state, since the output determination contact 48c is open, no signal is supplied to the photodiode 33a of the photocoupler 33 in the output determination section 25b. Therefore, the signal “H” from the determination power supply 35 is not sent to the photocoupler 33 but to the control signal converter 2.
The signal is output to the tri-state buffer 32 of FIG. As a result, the tri-state buffer 32 is turned off.

Therefore, even if the control signal of the subordinate system is input from the subordinate railway vehicle 5b to the input / output terminal 44 of the inter-railroad vehicle interface circuit 43, it is masked by the disconnected tristate buffer 32.

Here, it is assumed that the command switch 10b of the main cab 10 is opened. Then, the control signal conversion contact 48b of the relay circuit 48 and the self-control signal output contact 48
d is opened, and the output determination contact 48c is connected.

Accordingly, the slave control signal transmitted from master train 42a to slave train 5b is stopped, and the master control signal based on power supply 47 is output from output terminal 46.
Is not transmitted to the control device 11 of the main system.

On the other hand, the signal "H" from the power supply 47 is provided to the photodiode 33a of the photocoupler 33 in the output determination section 25b through the output determination contact 48c.
As a result, the signal “L” is output to the tri-state buffer 32 of the control signal conversion unit 25a, and is inverted and received by the tri-state buffer 32 as the signal “H”. As a result, the tri-state buffer 32 is set in an output enabled state.

Accordingly, when the command switch 6b of the slave cab 6 is connected in this state, the slave control signal is sent to the control signal converter 25a via the input / output terminal 44 of the inter-railway vehicle interface device 43. The input signal is converted into a main control signal using the photocoupler 29, and the output terminal 4
6 to the main control device 11.

As described above, in the railcar-to-railway interface device 43 according to the present embodiment, the relay circuit 14 as an insulating circuit converts the control signal of the main system into the control signal of the subordinate system. The conversion unit 25a converts a slave control signal into a master control signal using a photocoupler 29 that is an insulating circuit.

When a main control signal is generated by the output determination section 25b, the main control signal is transmitted to the main control device 11 and the sub system control signal in which the main control signal is rewritten. Is output to the slave control device 7.

On the other hand, if the main control signal is not generated by the output determination section 25b, the slave control signal is output to the slave control device 7. A main control signal having the same content is also output to the main control device 11.

Thus, when a control signal is not generated in the main railway vehicle, cooperative operation is performed by the control signal generated in the subordinate railway vehicle.

[0171] Therefore, the railcar-to-railcar interface device 43 is used effectively when the relationship between the main train and the slave train is not determined between the railcars and it is desired to transmit a control signal from the slave train to the master train. Can be.

Further, in the railway vehicle-to-railway interface device 43, since the input / output control signals are converted by using the insulating circuits 29 and 48, it is possible to prevent the occurrence of a round circuit.

Therefore, railway vehicles of different types can be easily and satisfactorily connected, and railway vehicles can be freely combined.

In the present embodiment, the railroad vehicle interface device 43 is mounted on the main railroad vehicle 42a. However, the present invention is not limited to this. For example, it is mounted on the subordinate railroad vehicle 5b. Or the railcar 42a,
5b may be used outside.

Further, the photocoupler 29 and the relay circuit 48 are used as an insulating circuit, but the present invention is not limited to this, and it is intended to prevent an electrical interaction between control signals at the input and output terminals. If so, various circuits and circuit elements can be applied.

Also, in the present embodiment, the first
Alternatively, the difference in the number of lead lines can be eliminated by encoding or decoding by the same method as the method described in the second embodiment.

The circuit configuration of the railroad-vehicle interface device 43 is merely an example, and various configurations can be realized as long as the same operation can be realized.

In the relay circuit 58, the coil 58a is excited by the operation of the photocoupler 33 when a command signal is input from the other vehicle 49b, and the normally closed contact 58b is opened. This prevents the control signal from being transmitted from the control signal conversion power source 56b to the other vehicle 49b when a command signal is input from the other vehicle 49b.

Further, the output judging section 57 determines whether the other vehicle 4

In addition, the output judging section 57 switches the output state of the control signal from each of the control signal conversion power supplies 56a and 56b based on the control signals output from the two control signal conversion sections 25a. It has.

The relay circuit 60 enables output from the control signal conversion power supply 56a when a control signal is input from the control signal conversion unit 25a on the input / output end 55a side, and outputs from the control signal conversion power supply 56b. Is impossible. On the other hand, when a control signal is input from the control signal conversion unit 25a on the input / output terminal 55b side, the control signal conversion power supply 56b

When the command switch 6b of the other vehicle 62b is connected before the command switch 6b of the other vehicle 62c, a control signal from the other vehicle 62b is input to the input / output terminal 64a of the railway vehicle interface device 63. .

The control signal from the other vehicle 62b input at the input / output terminal 64a is transmitted to the coil 68 of the relay circuit 68.
a is excited. As a result, the output permission contact 68b is connected, and the output non-permission contact 68c is opened. Due to the connection of the output non-permission contact 68c, the tri-state buffer 32 of the control signal converter 25a on the input / output terminal 64b side is in an output impossible state.

At the same time, the control signal from the other vehicle 62b input at the input / output terminal 64a is input to the control signal converter 25a on the input / output terminal 64a side and converted into a control signal for the own vehicle 62a.

Therefore, the tri-state buffer 32 on the input / output end 64a is in an output enabled state, and the control signal for the own vehicle 62a obtained by the conversion is transmitted to the control device 51 of the own vehicle 62a.

The output of the control signal from the tri-state buffer 32 on the side of the input / output terminal 64a causes one contact 60a of the relay circuit 60 to be in a connected state, whereby the control signal conversion power supply 56a is used for another vehicle 62c. A control signal is output from the input / output terminal 64b and transmitted to the control device 53 of the other vehicle 62c.

After that, even if a control signal is input from the other vehicle 62c, as long as the supply of the control signal from the other vehicle 62b, which is the preceding input, is maintained, the output is not permitted in the control signal converter 25a on the input / output 64b side. Is maintained.

Therefore, the railway vehicle-to-rail interface device 63 operates as the main system as long as the vehicle to which the control signal has been input first continues to supply the control signal.

As described above, in the railway vehicle-to-railway interface device 63 according to the present embodiment, the output determination section 6 has a function as an interlock circuit, and only inputs to the side to which the control signal has been input first. Accept. The state in which only the control signal of the first input is received continues until the supply of the control signal from the side permitting the input stops.
