DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 2 shows an external view of a main control unit. The main control device is composed of one master unit 20 and one or a plurality of slave units 22-1 ,. 1 in the figure
Although only the child device 22-1 is shown, since the other child devices have the same configuration, this child device 22-1 is also included.
Will be described as a representative of the child machine. The total number of the master unit 20 and the slave unit 22-1 is equal to the number of model trains running on the rail. The data bus of the child device 22-1 is connected to the parent device 20 by the plug 24 and the socket 26.
If a slave unit is further provided, the plug of the next slave unit is connected via the socket 26-1 of the slave unit 22-1. In this way, the data buses of all the child devices 22-1 are connected to the parent device 20.

Speed control knobs 28, 28- for adjusting the speed of the model train are provided on the master unit 20 and the slave unit 22-1, respectively.
1 is provided. Reference numerals 30 and 30-1 are forward / reverse changeover switches for switching the traveling direction of the model train. The switches 32 and 32-1 are switches for setting an address that specifies a model train to which each main control device corresponds, and are composed of, for example, a slide switch or a toggle switch. Here, four switches are provided so that up to 16 model trains can be controlled independently. The switches 34 and 34-1 are main power switches for turning on / off the power supply to the main control units 20 and 20-1.
Reference numerals 36 and 36-1 denote switches for turning on / off a headlight, a room light, or a horn, which are accessories of the respective model trains, and switches are provided as many as those accessories. The functions described up to this point are common to the master unit and the slave unit, and are configurations for creating control signals so that the respective units can independently control the operation of the corresponding model train.

On the other hand, only the master unit 20 has a function of transmitting a control signal to the model train, and the master unit 20 takes in all the control signals generated by the slave unit 22-1 and controls the master unit 20. It has a function of repeatedly sending a control signal together with a signal in the order of addresses. for that reason,
A pole 40 is attached to the base unit 20 by a socket 38, and an infrared LED 42 as an infrared light emitting element is attached to a tip of the pole 40 by a support tool 44. The support tool 44 is attached to the tip of the pole 40 so that the rotation angle can be adjusted, and the support tool 44 can be set at an appropriate angle so that infrared rays for transmitting a control signal generated from the LED 42 reach all model trains.

The base unit 20 is provided with a connector 46 capable of inputting an external control signal. The external control signal input from the connector 46 relates to control of other parts of the model railroad, such as switching of points. This is because, for example, when the points are switched using infrared rays from an infrared LED, it is possible to prevent malfunction due to interference due to simultaneous output of the train running control and point switching infrared rays. for that reason,
For example, when an external control signal is input as an H level signal of a pulse signal from the control device for point switching through the connector 46, the infrared ray L by the master device 20 is input.
It is used to temporarily stop the lighting of the ED 42.

To facilitate installing the infrared LED 42 in a higher position, an extension cord 48, such as that shown in the upper right of FIG. 2, can be used.
Connect the socket 38a at one end of the extension cord 48 to the base unit 20.
, And the pole 40 is connected to the socket at the other end to set the LED 42 at a high position.

FIG. 3 shows the structure of the internal circuit of the main controller. A plurality of slave units 22-1 to 22- (n-1) are connected to the master unit 20 via a data bus 25. The master unit 20 and the slave units 22-1 to 22- (n-1) generate control signals for the corresponding model trains, and addresses are assigned to them.

The internal circuit of the master unit 20 is shown in detail, and the description of the slave units 22-1 to 22- (n-1) is omitted. The internal circuit of each of the child devices 22-1 to 22- (n-1) is the LED 42 corresponding to the transmitting unit that transmits the control signal in the circuit of the parent device 20 and its output transistor Q.
3 and the resistors R12 and R13 connected thereto and the external control input terminal 46 are not provided, and the configuration is the same as that of the parent device 20.

The master unit 20 will be described in detail. A microcomputer 50 is provided for creating control signals and transmitting control signals. Four switches 32 for generating address signals are connected to the microcomputer 50, and 16 combinations of address signals can be generated by combining the switches 32 with ON and OFF. Speed adjustment knob 2 shown in FIG.
A variable resistor 28 a whose DC voltage is adjusted by 8 is connected to the microcomputer 50. According to the position of the speed adjustment knob 28, the DC of the middle point of the variable resistor 28a
The voltage is adjusted and is taken into the microcomputer 50. The fetched DC voltage is A / D converted inside the microcomputer 50 to be processed as a digital signal.

Reference numeral 55 is a direction conversion circuit, which outputs a signal for switching the traveling direction of the train to the comparator 52 and the switch SW.
6 and a bistable multivibrator (flip-flop circuit) 54, the output of which is connected to the microcomputer 50. The direction changing circuit 55 is a circuit for preventing such a situation because the train derails when the running direction is suddenly reversed when the train is running at high speed. That is, the power supply voltage divided by the resistors R3 and R4 is input to the non-inverting input terminal of the comparator 52, and the speed control voltage VR1 by the variable resistor 28a is input to the inverting input terminal. Comparator 52 to H
The resistors R3 and R4 are set so that the level signal is output at VR1 at which the train speed is almost zero. The output terminal of the comparator 52 is connected to the forward / reverse changeover switch SW6 via the diode D1 and the resistor R11. The two contacts switched by the switch SW6 are connected to the respective input terminals of the bistable multivibrator 54. The bistable multivibrator 54 can switch the state when an H level signal is applied to the input terminal, and holds the output state until then until the H level signal is applied. Since the output terminal of the bistable multivibrator 54 is connected to the microcomputer 50, the output of the bistable multivibrator 54 is inverted only when the speed of the train is near 0 even when the switch SW6 is switched. The sudden reversal is prevented.

Instead of the direction changing circuit 55, the same function can be achieved by the software of the microcomputer 50.

Assuming that the address of the train corresponding to the master device 20 is "1", the three on / off switches 36 corresponding to the headlight, room light and horn of the train having the address "1" are micro switches. It is connected to the computer 50. A power switch 34 connects and disconnects the power switch 35. C1 is a capacitor that absorbs fluctuations in the power supply.

The above-described circuit for the master unit 20 is provided in each of the slave units 22-1 to 22- (n-1) equally, and the address in the slave units 22-1 to 22- (n-1) is provided. Each slave unit 22-
A unique address is set to 1 to 22- (n-1). The master microcomputer 50 takes in the control signals generated by all the slaves 22-1 to 22- (n-1) via the data bus 25 and outputs them according to the order of addresses.

Next, the transmission unit 6 and the transmission control unit 19 (see FIG. 2), which are circuits unique to the master unit 20, will be described. The transmitter 6 includes a resistor R1 extending from the power supply side to the ground side.
2, a circuit including an infrared LED 42 and an NPN transistor Q3 is connected. The base of the transistor Q3 is connected to the microcomputer 50 via the resistor R13. The control signal is transmitted from the microcomputer 50 in the order of address through the resistor R13 to the transistor Q3.
The LED 42 is turned on by being installed in the base of the.

The external control input terminal 46 is connected only to the microcomputer 50 of the parent device 20. When an H level pulse signal is applied as an external control signal from the external control input terminal 46, the microcomputer 50 is programmed to stop sending the control signal to the output transistor Q3 during that period. The function executed by the program is the transmission control unit 19.

FIG. 4 shows the microcomputer 5 of the base unit 20.
0 function (A) and control signal (B) output from the master device 20
Indicates. In FIG. 4A, the microcomputer 50 includes a clock oscillator 62 and creates a clock signal based on the signal from the crystal oscillator 60. Variable resistor 28a
An A / D converter 64 is provided for taking in the speed control voltage VR1 from the device and converting it into a digital signal. The control signal generation unit 4a converts the header signal that prompts the train to start operation into an address signal from the switch 32, a forward / reverse direction signal from the forward / reverse switching circuit 55, and a digital signal in the A / D conversion unit 64. The converted speed control voltage VR1 and the accessory control signal from the switch 36 are fetched, and a control signal is created based on the clock signal from the clock oscillator 62. The function of creating a control signal is a slave unit 22-1 to 22-
The same applies to (n-1).

The control signal C1 shown in FIG.
Is generated by the header signal S1 and the address signal S as shown in detail below.
2, a forward / reverse signal S3, a speed control signal S4, and an accessory control signal S5. The control signals indicated by the control signals C2 to C16 are signals created by the child device, and have the same array of signals as the control signal C1 created by the parent device.

The control signals C2 to C16 generated by the slave unit are taken into the microcomputer 50 of the master unit 20 via the data bus 25, and are arranged in the order of addresses in the output control section 66 which only the master unit has as a function. It is assumed that there are 16 model trains now, and the master unit 20 and the slave units 22-1 to 22.
Assuming that 16 units are connected including-(n-1), 16 control signals C1 to C16 are arranged as shown in (B). This is one cycle, and this cycle is repeatedly transmitted from the LED 42.

FIG. 5 shows one model train 10. Infrared light receiving element 1 as a receiver on a part of the roof
Two are provided. Electric power used to rotate a motor for running a train and control its operation is received from wheels 69 via rails 68.

FIG. 6 shows the internal circuit of the train. A microcomputer 70 is provided to realize the function of the train control unit 14 shown in FIG. The power supply is taken in via the rail 68, and a capacitor C3 is provided to absorb the fluctuation of the power supply voltage. As the power supply, for example, a DC power supply of 12V is supplied. A regulator 76 having an output of 8V is connected to the power supply side in order to obtain a stable power supply of 8V from the power supply. Also, in order to obtain an even lower power supply of 5V, the regulator 76
A regulator 78 having an output of 5V is connected to the output terminal of the. As the regulators 76 and 78, for example, an IC marketed under the name such as a three-terminal regulator can be used. C2 and C1 are capacitors for absorbing fluctuations in the output voltages of the regulators 76 and 78, respectively.

A motor driver circuit 74 drives the DC motor 72 for rotating the wheels, and receives the 8V power output from the regulator 76 to drive the DC motor 72. The DC motor 72 changes the rotation speed by pulse driving. The motor driver circuit 74, based on the duty of the input drive pulse signal, D
It controls the rotation speed of the C motor 72, and an IC circuit is commercially available.

The microcomputer 70 is connected with four switches 80 for setting the address of this train. The light receiving element 12 receives a signal of infrared rays from the main controller, and its output terminal is connected to the microcomputer 70. As a power source for the light receiving element 12 and the microcomputer 70, a regulated 5 V power source is supplied by the regulator 78.

The microcomputer 70 includes the light receiving element 12
From the signal received from the main control unit, when the signal matches that of the train address, the motor driver circuit 74 is controlled according to the control signal to control the motor 7
2 is driven. Therefore, the microcomputer 7
0 compares the address set by the switch 80 with the address of the control signal, and drives the motor 72 only when the address of the control signal matches the address of the train.

The microcomputer 70 rotates the motor forward (L level) and reverse (H level) based on the control signal.
And the pulse data corresponding to the number of rotations of the motor are output as a signal for on / off control of the motor 72 and accessories.

FIG. 7 shows drive signals for driving the motor 72, and shows signals supplied from the microcomputer 70 to the motor driver circuit 74. The drive signal includes a drive pulse signal that controls the rotation speed of the motor 72 and a forward / reverse control signal that controls forward rotation and reverse rotation of the motor 72.

As the drive pulse signal, a signal S11 having the same pulse time of H level and L level is used as a basic pulse signal,
The number of revolutions is controlled by changing the duty of the pulse while keeping the cycle constant. In the case of a low speed, as shown by the signal S12, the H-level pulse time T1
Is shorter than the basic pulse. As a result, the section in which the motor is turned on is reduced, so that the motor rotates at low speed and the train also travels at low speed. When the time T1 at H level becomes 0, the motor stops. Conversely, high-speed drive pulse S14
Then, the number of revolutions is increased by making the time T3 of H level longer than the basic pulse. The longer the time T3, the more the motor is in the ON state, so the motor rotates at high speed, and the train also travels at high speed. The drive pulse S13 is a drive pulse for medium speed, in which the time T2 of H level has an intermediate length between the drive pulses S12 and S14.

The forward / reverse control signal is a signal for designating normal rotation and reverse rotation of the motor 72. When the forward / reverse control signal is at the L level, the motor drive circuit 74 rotates the electric current of the motor 72 in the forward direction so that the train runs in the forward direction. When the forward / reverse control signal is at the H level, the motor drive circuit 74 is operated so that the train runs in the reverse direction.
Causes the electric current direction of the motor 72 to be reversed and causes the motor 72 to rotate in the reverse direction.
As described in the direction conversion circuit 55 of FIG. 3, the forward / reverse control signal is inverted only when the traveling speed of the train is almost zero.

Next, referring to FIG. 8, the operation of the master unit in the main control unit is summarized. Master unit 20 and slave units 22-1 to 22
-(N-1) Create a control signal for the corresponding train at each. The master device 20 repeats the operation of fetching the control signal generated by the master device 20 and the control signals generated by the slave devices 22-1 to 22- (n-1) in the order of address and outputting from the LED 42. When the output is completed up to the last address, it returns to the first address again, and this cycle is repeated during operation.

If a pulse signal is input from the external control input terminal somewhere in this cycle, the operation of FIG. 8 is stopped, and the operation waits in a stopped state until the signal disappears. When the external control signal disappears, the flow of FIG. 8 is repeated again.

FIG. 9 shows the operation of the model trains 10-1 to 10-n. When the light receiving element 12 receives the infrared control signal sent from the main control unit 2, the header signal S1 included in the control signal recognizes the reception of the control signal, and then the address signal S2 of the control signal is transmitted to the train. Switch 8
It is determined whether or not it matches the address set by 0. When they match, it is determined by the next forward / reverse control signal S3 whether the rotation direction is forward or reverse. Next, the drive of the motor 72 is controlled based on the speed control signal S4. Next, on / off of the accessory is controlled based on the accessory control signal S5.

After that, the timer is reset, the timer is set again for a fixed time, for example, 1 minute or 2 minutes, and the reception of the next control signal is waited. Main controller 2
Since the control signal has been repeatedly sent from, the next control signal is received, and if the addresses do not match, the operation is continued and the next control signal is waited for.

The timer is provided to prevent the train from stopping in the tunnel even when the train cannot enter the control signal, such as when the train enters the tunnel. The fixed time is the time to continue the operation. The operation is stopped when the control signal cannot be received even after the elapse of the certain time, or when the control signal having the matched address signal cannot be received for the certain time even if the control signal is received.

The train stops at that position when the power supply to the rail is switched off or when the speed control signal shows a voltage of zero.
