Description

The present invention provides a device that gives a sense of presence to a driving operator and a viewer who operate a railway model system, and reproduces an audiovisual effect incidental to the railway model system.

Conventionally, in the travel of model trains, sound effects are generated and the lights are turned on for travel.
In general, a model railway vehicle is supplied with electric power from an electric circuit, such as a light and a sound effect generating circuit, from the same power source as a motor for the vehicle to travel.

FIG. 1 is a diagram showing a typical configuration example of a conventional model railway system.
The model railway system includes a controller (100) for controlling speed and direction, a model railway vehicle (200), and rails (150, 151) for running the model railway vehicle.

The rails (150, 151) are composed of two conductors for conducting electricity. The rails (150) and (151) are insulated from each other, and generally in the traveling direction of the model railway vehicle (200). On the other hand, the polarity of the DC power supply is the positive pole on the left and the negative pole on the right.
The rails (150, 151) also serve as a power supply line for the railway model vehicle (200) to receive electricity transmitted from the track on which the model railway model (200) travels and the controller (100).

The controller (100) feeds the DC output of the DC variable voltage source (101) to the rails (150, 151) through the polarity changeover switch (102) through the power transmission lines (103, 104).
The model railway vehicle (200) receives power from the rails (150, 151) by the mutually insulated wheels (220) and wheels (221), and receives electric power (222, 223) from the motor (201),
The sound effect generating circuit (210), the headlamp (202), the tail lamp (203), and the room lamp (204) are connected in parallel.

By changing the voltage of the DC variable voltage source (101), the speed of the motor (201) of the model railway vehicle (200) is changed, and by switching the polarity changeover switch (102), the rails (150, 151). The direction of travel of the model train vehicle (200) is determined by switching the polarity of the model and switching the rotation direction of the motor (201) of the model train vehicle (200).
When stopping the model railway vehicle (200), the DC variable voltage source (101) is operated to reduce the output voltage to zero, or the polarity changeover switch (102) is operated to supply power to the lines (150, 151). Implement by cutting.

The model railway vehicle (200) has a motor (201), a sound effect generating circuit (210), a headlamp (202), a tail lamp (203), and an interior lamp (204) connected in parallel to form a rail (150, 151). Therefore, if the power supply is stopped in order to stop the model railway vehicle, the operation of all circuits is stopped.

On the other hand, in actual railway vehicles, lights such as headlights, taillights, and interior lights will not be turned off unless the driver operates the vehicle while it is stopped. It is well known that various sounds are generated from the vehicle, such as noise generated by the operation, engine idle sound generated in diesel locomotives, and steam sound generated in steam locomotives.

Therefore, it deviated from the purpose of the railway model that faithfully reproduced the operation.

Provided is a device that can arbitrarily turn on and off lighting such as headlights, taillights, room lights, and sound effects even when a model railway vehicle is stopped.

In FIG. 1, the speed of the model train is controlled by varying the voltage of the DC variable voltage source (101) built in the controller (100) connected to the outside of the vehicle as means for driving the conventional model train (200). Since the travel direction was determined by changing the DC polarity with the polarity switch (102), the ramp and sound generation were stopped simultaneously with stopping the model train.

In FIG. 2, a speed model, a traveling direction, a lamp lamp, and a sound effect generating circuit are mounted inside a model railway vehicle (400) that receives a DC voltage source (300) via rails (150, 151).
By wirelessly performing bidirectional data communication, lights such as headlights, taillights, and interior lights, and sound effects can be arbitrarily turned on and off even when the model train is stopped.

The conventional model train stops all operations when the power supply is cut to stop the model train.

By implementing the present invention, even when the model train is stopped, lights such as headlights, taillights, room lights and sound effects can be arbitrarily turned on and off,
It is possible to provide a device that gives a sense of reality to the driver and viewers who operate the model railway system and reproduces the audiovisual effect incidental to the model railway system.
