Embodiments of the present invention will be described below with reference to the drawings.

In this embodiment, the present invention is applied to a railway model. FIG. 1 is a perspective view of the railway model. In this figure, a railroad model indicated by reference numeral 1 has two power supply rails 3a and 3b arranged in parallel on a roadbed 2 made of an insulator such as plastic. , 3b, a pulse voltage is applied from the control box 5 via the lead wire 6.

As shown in FIG. 2, a motor (electromagnetic part) M is mounted on the model vehicle 4, and an interior light (non-electromagnetic part) 7 is mounted inside the model vehicle 4. A light 8 (non-electromagnetic component) shown in FIG. 4 to be a headlight and a taillight is attached to the front and rear, respectively. The motor M, the interior lights 7 and the lights 8 are operated by a pulse voltage supplied through the wheels 4a of the model vehicle 4.

A main part of an operation control device 10 for controlling the operation of the motor M, the interior lights 7 and the lights 8 of the model vehicle 4 is incorporated in the control box 5. The operation control device 10 includes a fundamental frequency generator 10 as shown in FIG.
a, pulse generator 10b, duty controller 1
0c, amplifying unit 10d and traveling direction control unit 10
e.

The fundamental frequency generator 10a is composed of a multivibrator. This multivibrator includes gates (inverters) G1 and G2, resistors R1 and R2, a capacitor C1, and a gate G3.
1 and the resistor R2 determine the oscillation frequency of the PWM wave.

The pulse generator 10b comprises a capacitor C2, a resistor R3, a diode D1, and gates G4 and G5. Here, the capacitor C2 differentiates the output pulse of the gate G3. As a result, a rising timing pulse of the PWM wave is generated. The diode D1 in the pulse generator 10b performs the function of half-wave rectification of the differential wave. That is, it functions to remove the negative component of the differentiated timing pulse. Further, the gates G4 and G5 are waveform shaping gates, and serve to generate a narrow pulse.

The duty control section 10c includes a diode D2, a capacitor C3, a variable resistor VR1, and a resistor R4.
And a gate G6. Here, the diode D2 is a backflow prevention diode, and prevents the charge accumulated in the time constant circuit including the capacitor C3, the variable resistor VR1, and the resistor R4 from flowing out to the gate G5. The variable resistance V is controlled by the duty control unit 10c.
When the value of R1 is increased, the capacitor C3 and the variable resistor VR
The time constant determined by 1 and the resistance R4 increases. That is, the duty and, consequently, the pulse width are increased. Also,
Gate G in the duty control section 10c
Reference numeral 6 denotes a waveform shaping gate which shapes the pulse smoothed by the time constant circuit into a pulse having a predetermined width. As a result, the duty can be continuously changed from minute to 100%.

The amplifying unit 10d includes a transistor Tr1 and diodes D3 and D4. Here, the pulse input to the gate of the transistor Tr1 is amplified by the transistor Tr1, and a low impedance load can be driven. Note that the diode D3 removes overshoot and the diode D4 removes undershoot to shape the pulse.

The traveling direction control unit 10e comprises a switch 15 for inverting the polarity of a pulse connected to the power supply rails 3a and 3b.

The operation control device 10 includes various rectification circuits, and these rectification circuits are connected to the interior lights 7 and the lights 8. More specifically, a full-wave rectifier circuit 11 (FIG. 2) is connected to the interior light 7 that is to be always lit regardless of the traveling direction, while a half-wave rectifier circuit 11 is connected to the light 8 that is to be lit according to the traveling direction. The rectifier circuit 12 (FIG. 4) is connected. In the latter light 8, the direction of current flow in the rectifier circuit 12 is changed between the two lights so that only the light 8 on the front side in the traveling direction is turned on when the model vehicle 4 travels. It is. FIG. 4 shows one of them as a representative.

Next, the operation of the railway model 1 will be described.

The model vehicle 4 is connected to the power supply rails 3a and 3b.
Is set, and in this state, the main switch 13 of the control box 5 is turned on. Then, for example, a pulse voltage having a small duty (FIG. 5A) is output from the control box 5 and applied to the power supply rails 3a and 3b. When the pulse voltage with a small duty is applied, the interior light 7 and the headlight 8 in the model vehicle 4 are turned on, but the motor M is not driven. This is because a voltage sufficient to drive the motor M cannot be obtained because the pulse width is small.

Next, when the duty is somewhat increased by changing the resistance of the variable resistor VR1 by the rotary knob 14 of the control box 5 (FIG. 5B), the interior light 4
And the headlights 8 maintain the lighting state,
The motor M is driven. Thereby, the model vehicle 4 starts running.

When the duty is further increased (FIG. 5C), the speed of the model vehicle 4 increases. This is because the operation time of the motor M becomes longer. In this case, if the duty is set to 100% and a constant voltage is applied to the motor M or the like, the speed of the model vehicle 4 is maximized.

The switching of the traveling direction of the model vehicle 4 is performed as follows.
This is performed by a traveling direction switching switch 15 provided in the control box 5.

According to the railway model 1 of the embodiment described above, the following effects can be obtained.

According to the railway model 1 described above, the interior lights 7 and the lights 8 are continuously operated during the pulse voltage application regardless of the pulse width modulation (duty is changed in the embodiment). The operation of the motor M can be controlled by modulating the pulse width. In this case, since the brightness of the interior lights 7 and 8 hardly changes,
It will be possible to realize a railway model that is close to the real thing.

FIG. 6 shows another example of the operation control device. In the operation control device 21, when an L pulse is applied to the gate G of the transistor TR1 and an H pulse is applied to the gate G of the transistor TR2, an H pulse is applied to the gate G of the transistor TR3 and an L pulse is applied to the gate G of the transistor TR4. A positive pulse voltage is applied to the rail 3a, and the power supply rail 3b is grounded.

Conversely, H is applied to the gate G of the transistor TR1.
When an L pulse is applied to the gate G of the transistor TR2 and an L pulse is applied to the gate G of the transistor TR3 and an H pulse is applied to the gate G of the transistor TR4, the power supply rail 3a is grounded and the positive power pulse is applied to the power supply rail 3b. A voltage is applied. In this way, the polarity inversion of the power supply rails 3a and 3b is performed.

Here, for example, when a control pulse voltage is applied to the power supply rail 3a, an H pulse is applied to the gate G of the transistor TR2, an H pulse is applied to the gate G of the transistor TR3, and the transistor T
An L pulse is applied to the gate G of R4 to control the CPU pulse output applied to the gate G of the transistor TR1.

On the other hand, when a control pulse voltage is applied to the power supply rail 3a, an H pulse is applied to the gate G of TR1 and an L pulse is applied to the gate G of the transistor TR3.
Pulse, an H pulse is applied to the gate G of the transistor TR4, and the CPU applied to the gate G of the transistor TR2.
Control the pulse output.

FIG. 7 shows a control pulse signal obtained as described above. In the pulse signal of FIG. 7,
A wide pulse indicated by a waveform A is output at a constant period, and a narrow pulse indicated by a waveform B is output at a constant period between the wide pulses.

The wide pulse is used to control the operation of the motor M. When the pulse width becomes a predetermined width or more, the motor M is driven and the model vehicle 1 runs. As the pulse width further increases, the speed of the model vehicle 1 increases accordingly. Conversely, when the pulse width becomes smaller than the predetermined width, the motor M and thus the model vehicle 1 stop.

The narrow pulse is used to turn on the interior light 7 and the like, and the interior light 7 and the like are kept lit while the narrow pulse is emitted. Of course, even while the wide pulse is being output, the interior light 7 and the like are turned on. As a result, the operation control of the motor M can be performed while maintaining the lighting state of the interior light 7 and the like.

FIG. 8 shows another example of a control pulse signal obtained by the operation control device 21 of FIG. In the control pulse signal of FIG. 8, the motor M is controlled by a pulse train composed of pulses of different widths. The average of the pulses acting on the motor M is changed by changing the width of each pulse included in the pulse train. By changing the voltage, the operation control of the motor M and thus the model vehicle 1 is performed. Since the pulse period is short, the interior lights 7 and the lights 8 can be considered to be always lit. As a result, the interior lights 7
The operation control of the motor M can be performed while maintaining the lighting state such as the above.

FIG. 9 shows still another example of the operation control device. In the operation control device 30, AC is full-wave rectified by a full-wave rectifier circuit 31, smoothed by a diode D1 and a capacitor C1, and controlled at a constant voltage by a regulator. The output from this regulator is resistor R1, transistor T
The power is supplied to one of the power supply rails 3a and 3b via R1 and TR2, and the other of the power supply rails 3a and 3b is grounded. In this case, which is grounded is determined by switching of the traveling direction switch 15. Thus, the polarities of the power supply rails 3a and 3b are determined.

In such an operation control device 30, when the variable resistor VR1 is adjusted, the base voltage of the transistor TR2 is controlled, and a pulse signal C for motor control (FIG. 10)
The pulse width of (a) is controlled. That is, in FIG. 9, when the variable resistor VR1 is raised, the base voltage of the transistor TR2 increases, and the pulse width increases. Conversely, when the variable resistor VR1 is raised, the base voltage of the transistor TR2 decreases, and the pulse width of the pulse signal C decreases.
Thereby, the operation control of the motor M is performed.

On the other hand, a PWM generator 32 located on the lower side of FIG. 9 is a control unit such as an interior light, and the multivibrator 33 oscillates at a predetermined oscillation frequency, and the transistor TR
3 is switched. here,
To brightly light the interior light 7 and the like, the variable resistor VR2
Is changed to increase the pulse width of the pulse signal D (FIG. 10B). This makes it possible to brighten only the illumination such as the interior light 7 without substantially changing the speed of the motor M.

FIG. 10C shows a control pulse waveform obtained by the operation control device 30 shown in FIG. In FIG. 9, reference numeral 34 denotes a circuit for limiting the current when an excessive load is applied to the rail.

Although the control pulse waveform is created from AC here, it is needless to say that the control pulse waveform can also be created from DC.

Although the embodiments of the present invention have been described above, the present invention is not limited to such embodiments, and it goes without saying that various modifications can be made without departing from the scope of the invention. Absent.

For example, according to the above embodiment, the railway model 1
Although the operation control of the motor M, the interior light 2, the head lamp and the tail lamp in the above has been described, the present invention can be applied to control of other electric parts or electronic parts, for example, general accessory parts of a railway model such as lighting control of certification in a station yard.

Further, the operation control device of the above embodiment is not limited to the control of electric parts or electronic parts related to a railway model,
The present invention is also applicable to control of electronic components or electronic components related to a car racing model. In addition, the present invention can be applied to electronic components such as robot toys or control of electronic components.

In the above-described embodiment, the operation control apparatus for a toy including both an electromagnetic component and a non-electromagnetic component has been described. However, a pulse width which can be operated between these non-electromagnetic components includes two or more types of electromagnetic components. The present invention can be applied to the case where there is. In this case, it is possible to control the operation of another electromagnetic component that operates at a relatively large pulse width while maintaining the operating state of the electromagnetic component that operates at a relatively small pulse width.

In the above embodiment, the operation control of the motor M of the model vehicle 4 and the interior lights 7 and the lights 8 has been described. However, the operation control of the signal 20 shown in FIG. In some cases, the signal 20 must be lit regardless of the operation of the model vehicle 1. Conventionally, the signal 20 was driven by a different power source than the model vehicle 1. According to the present invention, the configuration of the railway model itself can be simplified.

Also, power can be supplied to other accessory parts of a railway model having a motor, such as a railroad crossing model. In this case, a rectifier circuit is provided as needed.

[0054]

According to the operation control device of the present invention, during application of a pulse voltage, a specific part can be operated intermittently irrespective of the pulse width modulation, and other parts can be pulsed. The operation can be controlled by modulating the width. In this case, if a rectifier circuit for rectifying a current applied to another component is provided, the other component can be continuously operated regardless of pulse width modulation.
