[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drive control device for a model railway vehicle, and more particularly to a device for controlling the running of the vehicle and the lighting of lights such as headlights, tail lights, and interior lights.

[0002]

2. Description of the Related Art A conventional railway model is also operated by turning on a headlight, a taillight, and a room light, but generally, the power is taken from the same power supply as a motor for driving power. I have. Here, FIG. 5 shows a conventional controller.
1 shows a configuration example of a model railway vehicle. In FIG.
The controller 100 has a DC variable voltage source 101 and a polarity switching switch.
It is composed of a switch 102 and runs on a model railway vehicle 200.

3. Turn on the tail light 204 and the interior light 205,
203 and taillight 204 are characteristics of diodes 206 and 207
Illuminates only one of them. This headlight 203
And the tail light 204 are connected to the DC power applied to the terminals 208 and 209.
Normally, one of them lights up depending on the polarity of the pressure.
When the vehicle heads forward according to the direction of travel of the vehicle, the headlight 203
The tail lamp 204 is set to be turned on when traveling.
However, as described above, the power source for vehicle lighting is
When the power is taken from the same power supply as the motor, the headlight, the taillight, and the interior light are turned off when the power is turned off to stop the vehicle . This is obviously not interesting for railway enthusiasts because it is clearly different from the actual railway.

In order to avoid such a situation, for example, a method as shown in FIGS. 2 and 3 has been developed. FIG. 2 shows a method using a high-frequency alternating current.
On the 0 side, for example, a high frequency AC 22 is superimposed on a DC power supply 21 capable of voltage control. On the vehicle 30 side, a high-frequency AC 22 is extracted from the superimposed electric signal using a capacitor 32 or the like, and the extracted high-frequency AC 22 is used for lighting each light 31, and the DC component is used for driving a motor 34. According to this, even if the vehicle 30 is stopped, the headlights, tail lights, and interior lights can be turned on, but the headlights and tail lights of the leading car are turned on at the same time, impairing the sense of reality,
Also, it is difficult to switch before and after lighting.

FIG . 3 shows a method of mounting the receiver 35 on the vehicle 30 side. On the controller 20 side, several types of pulse signals having different frequencies are superimposed on the power supply 24 from, for example, a plurality of pulse signal sources 25. On the vehicle 30 side, a receiver 35 including a tuner 36 and a converter 37 capable of selectively receiving the pulse signal is provided, and each light 31 is selectively turned on by the receiver 35.

It is necessary to mount a receiving board on all of them, and furthermore, a dedicated switch 26 controller is required, so that the cost increases. There is also a problem that it cannot be used for a conventional model vehicle having no receiving board.

[0006]

As described above, according to the conventional configuration, the lights are turned off when the vehicle stops,
There is a problem that the way of turning on the headlights and taillights is different from that of the actual vehicle and the sense of reality is poor, and that the lighting cannot be performed unless a receiving board is mounted for each vehicle. Therefore, in the present invention, the conventional vehicle and the
It can be applied to the conventional controller as it is,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a block diagram of one embodiment of the present invention.

Is a mixing circuit, and 13 and 14 are forward / reverse changeover switches.

[0011] By the way, this device and the power source for driving a vehicle,
It is connected to a conventional model vehicle controller (hereinafter referred to as a main body) having a voltage control device for controlling the output voltage (feeder voltage) of the driving power supply and a switching means for switching the polarity of the voltage-controlled power supply output. Be driven.

[0012] From the main body, a DC voltage of 12 to 15 V and a DC voltage corresponding to a target traveling speed for driving the vehicle are supplied to the apparatus.
The feeder voltage controlled to １２12 V is input. This input DC voltage is compared with a reference voltage by the power supply voltage drop detection circuit 1. When the input DC voltage becomes lower than 12 V, the power supply voltage drop detection circuit 1 turns on the alarm LED lamp 3 and stops the oscillation of the reference oscillator 6.

The overcurrent detection circuit 2 monitors the flowing current.
If a current exceeding the specified value flows, the alarm LED
The lamp 3 is turned on to stop the oscillation of the reference oscillator 6. You
That is, the power supply voltage drop detection circuit 1 and the overcurrent detection circuit
2 and the alarm LED lamp 3
Make up. DC output through the overcurrent detection circuit 2
The voltage is applied to the power supply of the reference oscillator 6 and
It is input to a booster circuit 4 composed of a pull-up converter.

Here, when the vehicle is stopped, the feeder input voltage controlled for driving the vehicle is 0 V, so that the booster circuit 4
In this case, the DC input voltage is boosted to DC 30 V and output.
When the vehicle is running at full speed, the input voltage of the feeder is approximately 12 V DC, so the boosted voltage in the booster circuit 4 may be lower than this. The voltage control for determining the boosted voltage is executed by the pulse voltage control circuit 5.

Meanwhile, the reference oscillator 6 is always rectangular wave oscillator the oscillation frequency of about 20KHz which oscillates together with the power ON unless there is no abnormality in the power supply circuit, the output of which is input to the differential pulse generating circuit 8. The differential pulse generation circuit 8 differentiates the output of the reference oscillator 6 to narrow the pulse width of the oscillator output to about 5 μsec. At this time, the pulse width can be controlled by changing the constant of the differentiating circuit. Since this pulse width is the pulse width of the pulse applied to each light, when the pulse width is reduced, the power applied to each light is reduced, whereby the brightness of the light can be adjusted.

The output of the differential pulse generating circuit 8 is amplified by the voltage amplifying circuit 9 up to the output boosted voltage of the boosting circuit 4, and the current is amplified by the current amplifying circuit 10 with the output impedance lowered. The voltage-current amplified pulse is superimposed on the input voltage of the feeder by the mixing circuit 12. And then
This superimposed voltage signal is supplied to the forward / reverse switch 13 or 1
4 is input to the feeder line of the model vehicle as a forward rotation output or a reverse rotation output.

FIG. 4 shows an output to the feeder line.
4 shows an example of an output waveform of a superimposed voltage signal (mixing circuit 12).
You. In FIG. 4, FIG. 4A shows that the feeder voltage is 10V.
FIG. 4B shows the output when the feeder voltage is 0V.
4 shows an example of a force waveform. Now, as shown in FIG.
The output waveform of the superimposed voltage signal output to the
It consists of a V-feeder voltage and a pulse portion having a peak-to-peak voltage of 30 V, and both have polarity. The polarities of these portions can be simultaneously switched by the forward / reverse switch 13 or 14. This change of polarity is based on the forward movement of the model vehicle,
The reverse mode is switched, but the model vehicle is similar to the vehicle shown in FIG.
The headlight is turned on at the voltage polarity when moving forward, and
Since the light is turned on, the way the model vehicle travels
The lighting direction of the headlight and taillight is switched with the direction, and when moving forward
, The headlights of the frontmost vehicle and the taillights of the last vehicle light up,
When traveling backwards, the headlights of the rearmost vehicle and the taillight of the frontmost vehicle are lit.
Light up. Also, the interior light has either a forward or backward voltage pole.
It also lights up in sex. Therefore, the same forward and reverse turning off
The traveling direction of the model vehicle and the lighting directions of the headlights and the taillights are switched by the changeover switches 13 or 14, thereby greatly increasing the sense of reality.

Next, the operation for actually driving a model railway vehicle using the present apparatus will be described. First, this device is connected to the main body. At this time, the feeder voltage is set to 0 V, and the polarity is fixed in the forward direction. If the output of the
Connected to output to the feeder line, and power on the main unit
To As a result, the peak-peak voltage 3
When a 0 V pulse is output and the forward / reverse switch 13 or 14 is switched from the OFF position to the forward (forward) position,
While the vehicle is stopped, the headlight of the frontmost vehicle, the taillight of the rearmost vehicle, and the interior light are turned on. At this time, the peak
Pulse voltage of 30V is applied to both driving motors
Applied, but the drive current is smoothed to the vehicle drive motor.
The smoothing reactor is connected in series to make
Processes the magnetic energy stored in this smoothing reactor
Is connected to a circuit composed of diodes, etc.
Drive current is not applied to the motor by applying pulse voltage.
The motor does not move and the vehicle does not move because it does not flow.
No.

When the mode is switched to reverse (reverse), the headlight of the rearmost vehicle, the taillight of the frontmost vehicle, and the interior light are turned on.
At this time, the brightness of the light can be adjusted by changing the pulse width by changing the differential constant of the differential pulse generation circuit 8. When the feeder voltage of the main body is gradually increased with the forward / reverse changeover switch 13 or 14 in the forward (forward) position, the train starts and gradually increases in speed. When the feeder voltage becomes 12 V, the speed becomes highest. The brightness of the light of the vehicle is kept constant even if the train speed changes by the function of the pulse voltage control circuit 5. Needless to say, it is only necessary to gradually lower the feeder voltage when stopping. In this case, even after the vehicle stops, the headlight of the frontmost vehicle, the taillight of the frontmost vehicle, and the interior light continue to light.

When shifting to reverse (reverse), the forward or reverse switch 13 or 14 is set to the reverse (reverse) position while the vehicle is stopped. Thereby, the headlight of the rearmost vehicle, the taillight of the frontmost vehicle, and the interior light are turned on. To start and increase the speed, the feeder voltage of the main body should be gradually increased. In FIG. 1, the forward / reverse switch 13 or 1
Since two sets 4 are provided, the running directions of the model vehicles on the two feeder tracks can be controlled independently. In this embodiment, the apparatus has been described as being separate from the main body. However, it goes without saying that the apparatus may be integrated with the main body.

[0021]

According to the present invention, the pulse generating means and its output
Pulse width control means for controlling the pulse width of the force pulse signal; and superimposing means for superimposing the controlled pulse signal on the DC voltage of the vehicle driving power supply, wherein the polarity of the output superimposed signal of the superimposing means is switched by the switching means. Thus, the running direction of the model vehicle and the lighting direction of the light can be switched at the same time, so that 1) headlights, tail lights, and interior lights can be turned on even while the vehicle is stopped. 2) Conventional controllers and models The vehicle can be used as it is, and it is economical. 3) The driving direction and the lighting of the headlight and taillight can be controlled by the same switch .
There is an advantage that an apparatus such as an automatic traffic signal which operates by detecting the traveling direction of the vehicle or an automatic level crossing can be used as it is depending on the polarity of the voltage .
