[0014]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic overall configuration diagram of a railway model device 10 to which a central control system for a railway model according to the present invention is applied. The system preferably includes a software section stored in a storage device of the personal computer 12 and executed by a central processing unit (CPU), and an analog power supply for supplying power for driving motors for trains and switches. It comprises a unit 20 and signal processing units 30 and 40 for trains and switches.

The personal computer 12 outputs a serial coded control signal to the power supply unit 20 by executing the centralized control software. personal·
The computer 12 and the power supply unit 20 are, for example, RS232
It is connected via a serial port 18 such as C. The power supply unit 20 has a built-in DC stabilized power supply that supplies driving power for a train and a switch, and generates a DC voltage. Then, the control signal in the serial format is superimposed on the DC voltage signal, and the superimposed signal is output to the output line 22. The output line 22 of the power supply unit 20 is connected to an appropriate portion of a rail 24 that is a conductor. Train 30 receives a superimposed signal from rail 24 via wheels 26. On the other hand, the interlocking equipment room 40 that controls the plurality of switch equipment groups P1 and P2 takes in the superimposed signal from the appropriate part of the rail via the reception line 38. The signal processing unit of the train 30 and the interlocking equipment room 40 separates the received superimposed signal into a motor driving DC component and a control signal component again. The motor driving DC component is used as a motor driving power source (part is also used as a power source for a signal processing unit). After the separated control signal is decoded into a signal format for motor control, the operation of the drive motor of the train and each switch is controlled based on the control information.

FIG. 2 shows an example of a screen display by centralized control software executed in the personal computer 12 of FIG. On the display screen 14, items selectively input by the operator are displayed. At the top of the screen is a menu bar 60 for basic software operations.
Is provided. In the upper half of the screen, a switch setting sign 70 for setting the route of the train is shown, and in the lower half, a train setting sign 8 for setting the speed and direction of the train.
0 is shown. It is preferable that these setting signs are in a format that makes it easy to visually grasp each setting made by the operator himself.

In the setting operation, the operator first clicks the "communication line" sign at the left end of the menu bar 60 with a mouse or the like to display a pull-down menu sign 61. Thereby, a communication port for connecting the personal computer 12 and the power supply unit 20 is selected. This selection is performed to select one of the communication ports when there are a plurality of communication ports. Personal computer 12
Since the control signal sent from the controller to the power supply unit 20 is in a serial format, the communication port is a serial port such as RS232C.

Next, by clicking the "control station" sign on the menu bar 60, a pull-down menu sign 6 is displayed.
2 is displayed. Thereby, the control target station related to the setting of the route of the train is selected. For example, "yama station", "sea station", "terminal station (right)", "terminal station (left)",. . And so on. Each control station such as “Yamanoeki” corresponds to one interlocking equipment room (reference numeral 40 in FIG. 1). The interlocking equipment room corresponding to each control station is responsible for a plurality of switches installed near the control station. The installation location of the interlocking equipment room on the actual model does not necessarily have to be in the corresponding control station premises, but is preferably installed at least in the vicinity of a plurality of switches under its control. This is for minimizing the wiring (reference numerals 42a and 42b in FIG. 1) from the interlocking equipment room to each of the switches.

In the example of FIG. 2, "Umi no Eki" is selected as the control station, and the track diagram near "Umi no Eki" is displayed (the station building itself of "Umi no Eki" is not displayed). . A plurality of tracks and their connection points exist on the track diagram.
Each of the switches P1 to P4 on the actual model is installed at each of these connection points, and the train is switched by switching each of the switches at the "localized" position and the "inverted" position. Will be changed. However, on the setting screen shown in FIG. 2, instead of directly setting the positions of the switches P1 to P4, a plurality of passing points A,
B. . By selecting H, the route of the train is set. Point A is the starting point in this track diagram, and point H is
This is the landing point in this track diagram. Then, once the route of the train has been set, the position of the associated switch is automatically determined. Thus, the course can be set while visually grasping the course easily.

For example, in FIG. 2, A
A screen is displayed when the user clicks the setting button sign 72 after clicking the points D, D, E, and H.
As shown, points A and D are connected, and points E and H are displayed in a connected state. Such a course is realized if the switch P1 is "inversion" and P3 and P4 are "localized", so that the positions of the switches P1, P3 and P4 are automatically determined. (Here, the case where the train goes straight is referred to as “localization”, and the case where the train turns right and left is referred to as “opposite”).
In this example, the position of P2 is arbitrary. Various methods are conceivable for visually indicating the set course, in addition to the illustrated example.

FIG. 4 shows an example of a switch setting sign 70 for a control station other than the "sea station" shown in FIG. FIG. 4A is a track diagram of “Yamanoeki”. 7 passing points A
To G are displayed. There are three connection points of the track, and the switching devices P1 to P3 exist at these locations.
FIG. 4 (B) is a railroad map sign of “terminal station (right)”. 6
There are three passing points AF. There are four connection points of the track, and there are switching points P1 to P4, respectively. FIG.
(C) is a railroad map mark of "terminal station (left)". There are six passing points AF. There are switching devices P1 to P4 at the four connection points, respectively. In any of the track map markings, the passing points A, B,. . Is selected and set, whereby each of the switches P1, P2. . Is automatically determined. The passing points A, B. . Is not limited to the above example, since the position and number of the lines depend on the pattern of the track diagram. However, usually
As many as necessary to set feasible routes in the track diagram.

Next, a train to be controlled is selected by using the train setting sign in the lower half of FIG. 2, and its speed and direction are determined. "TN = 1", "TN = 2". . Indicates that the train identification numbers are “1” and “2”. Each train is assigned a unique identification number, and the signal processing unit in each train stores its own identification number. The train name (for example, “Aoba”) is displayed in a horizontally long frame 82 immediately below the identification number. A vertically long scroll frame 83 therebelow is a speed setting sign, and the user can select from the highest speed to the lowest speed (stop) by moving the scroll bar up and down. Each time the frame below the scroll bar is clicked, the display of “before” and “after” is switched, and the forward or backward traveling direction can be selected.

As described above, after setting the switch point switching position and the speed and direction of the train, when the "operation start" sign 63 on the menu bar 60 is clicked, the code is coded based on the set information. A control signal is generated, and the generated control signal is transmitted from the selected communication port to the power supply unit 2.
Sent to 0.

By selecting the "end" sign 64 on the menu bar 60, the centralized control software can be ended.

"Write ID" sign 6 on menu bar 60
By selecting 5, the screen shifts to an ID writing screen for writing a unique identification number for each train and each interlocking equipment room. FIG. 3 shows an example of the ID writing screen. First, the operator selects whether the object is a train or an interlocking equipment room by two button indications on the left side, then selects an ID number to be written by the 0 to F button indications in the center, and a write or cancel button indication on the right side. The writing is executed or the writing is canceled by selecting. When performing ID writing, the train or the interlocking equipment room other than the writing target is removed from the model layout.

FIG. 5 shows the configuration of the personal computer 12 for executing the central control software and the power supply unit 20.
Is schematically shown. The central processing unit 115 controls and manages the operation of each component. The input unit 111 includes input devices such as a keyboard and a mouse, and an input interface that passes input information from these devices to the central processing unit 115. The display unit 113 includes a display device and the central processing unit 1.
And a display interface for displaying information from the display 15 on the display screen 14. The storage unit 117 stores codes corresponding to setting information such as the identification number of the train and the interlocking equipment room, the direction and speed of the train, and the position of each of the switches controlled by the control station. The central processing unit 115 includes the input unit 1
Based on the setting information passed from the storage unit 11, a required code is requested to the storage unit 117, the code is extracted from the storage unit 117, and a coding control signal is generated. After that, the generated coded control signal is passed to the output unit 119. The output unit 119 outputs the coded control signal in a serial format. This is the control signal output to the transmission line 18 in FIG.

The power supply unit 20 has a built-in DC stabilized power supply 121 for supplying driving power for a train and a switch, and generates a DC voltage. Then, after the control signal in the serial format is superimposed on the DC voltage signal in the signal superimposing section 123, the superimposed signal is output to the output line 22.
The output line 22 of the power supply unit 20 is connected to an appropriate position on the rail.

FIG. 6 is a table schematically illustrating the contents stored in the storage unit 117 of FIG. In FIG. 6A, the identification number of the train and the corresponding 8-bit binary ID code are shown side by side. For example, when the input identification number of the train is “1”, the central processing unit 115 outputs the ID code “00010” corresponding to the identification number “1” of the train.
001 ”is retrieved from the storage unit 117. In FIG. 6B, the direction of the train and the corresponding 1-bit binary direction code are shown side by side. Forward is "0", reverse is "1"
Indicated by the code FIG. 6C shows the train speed and the corresponding 3-bit binary speed code. Although the speed setting scroll bar on the setting screen of FIG. 2 is continuous, it is stored in eight stages by a 3-bit speed code in an actual storage unit. Therefore, the speed code at any stage is extracted according to the position of the scroll bar.

FIG. 6D shows an identification number of the interlocking equipment room,
The corresponding 8-bit binary ID code is described in parallel. These are the same as in the case of the train described above. Although not shown, the position (“localization” or “reversal”) of each of the plurality of switches corresponding to the specific train course set by the screen display of FIG. 2 is also stored in the storage unit. Is stored in For example, if an 8-bit code is used, one interlocking equipment room can control up to eight switches. In this case, “0” and “1” of each of the 8 bits correspond to “localization” and “inversion” of each switch. The number of bits and the binary value of each code shown in FIG. 6 are examples, and the present invention is not limited to these.

FIG. 7 shows a central processing unit 1 using codes extracted from a storage unit in accordance with input operation information.
15 shows a preferred example of the coding control signal generated by the output unit 15 and output from the output unit. FIG. 7A shows a coded control signal for determining the direction and speed of the train. This is a form in which the ID code of the target train is repeated twice, followed by a data code consisting of a direction code and a speed code. Thereafter, a spare bit for extension may be provided. FIG. 7B shows a coded control signal for determining the positions of the points P1 to P8 in the interlocking device room. This is a form in which the ID code of the target interlocking device room is repeated twice, followed by a data code consisting of a switch group code.

The reason why the ID code is repeated twice as shown in FIG. 7 is to ensure accurate signal transmission. That is,
At the stage when the signal processing circuit of the train or the interlocking equipment room receives the first ID code, it waits as it is, and then the same ID code
When the code is received, it is determined that the first ID code is correct. Then, the reception of the data code is permitted.

FIG. 8 shows an embodiment of the power supply section 20 in FIG. The serial control signal from the personal computer 12 shown in FIG. 1 is input from the upper left of the circuit in FIG. 8, and is converted into a 30 kHz pulse modulated signal at the upper right. On the other hand, the lower half circuit of FIG. 8 constitutes a constant voltage stabilized power supply 121 that rectifies an AC commercial power supply and generates a DC voltage. In the constant voltage power supply 121, a DC voltage of 12V is generated and used as a drive power supply for driving the motors of the train and the switch.

At the output point 43 of the DC voltage of 12 V,
A superimposition signal is generated by superimposing the above-mentioned pulse modulation signals, and is transmitted to the transmission line 22 connected to the rail.

FIG. 9 shows an embodiment of the signal processing circuit in the train 30. The superimposed signal transmitted to the rail is input to the train signal processing circuit via the train wheel 26. The input signal is separated by a signal separation unit 153 into a pulse component as a control signal and a DC component as a drive power supply. In the illustrated example, a pulse component is extracted using the frequency characteristics of the coil.

After the separated DC components are rectified, a constant voltage circuit generates 12 V as a driving power supply 157 and 5 V as a logic circuit power supply 156.

On the other hand, the separated pulse component is supplied to the receiving unit 1
54, where it is amplified and shaped. At this point, the pulse signal containing the control information remains in the serial format. After that, the pulse signal is sent to the decoding unit 155 and input to the terminal a0. Decoding section 155 first determines whether or not the ID code included in the received pulse signal matches its own ID. As described above, after it is determined that the ID code is the same twice, the received ID is compared with its own ID.

When the decoding section 155 determines that the ID coincides with its own ID, the decoding section 155 converts the data signal including the control information into a parallel format, and outputs it to b0 to b7. The output data signal is sent to motor drive section 158. The motor drive unit 158 switches the direction of the drive current to the motor in accordance with the control information to reverse the traveling direction, or changes the motor rotation speed to a predetermined speed. The motor driving unit 158 in FIG.
9 is an embodiment in which the driving of the first embodiment is performed. The motor 159 is controlled according to the code output of the motor driving IC.

FIG. 10 shows an embodiment of the signal processing circuit in the interlocking equipment room 40. The superimposed signal transmitted to the rail is input to the signal processing circuit of the interlocking equipment room 40 via the reception line 38 connected to the rail. Interlocking equipment room 4
The signal processing circuit of 0 is exactly the same as the signal processing circuit of the train 30 shown in FIG. In the interlocking device room 40, a switch driving unit 168 for driving a plurality of switches (including four switches 170 in the illustrated example) under its control is provided.

As described above, the centralized control system for trains and points in a model railway according to the present invention has been described by showing one embodiment. However, the components of the system are exemplified by software, analog circuits, and the like. The present invention is not limited to the logic circuit, and any system configured according to the basic principle of the present system is included in the scope of the present invention.

[0040]

According to the present invention, when a plurality of trains and a plurality of switch groups are arranged on a model railway, the speed and direction of each train and each switch group (station section) are included. It is possible to independently control the position of each switch. In this control, a unique control command can be transmitted to each train and each switch via a rail. Therefore, it is not necessary to separately provide wiring for each of the switches or the group of switches, and it is not necessary to consider a complicated wiring and circuit installation method as in the related art on the layout. Further, the present invention can be easily applied to a large-scale railway model. Further, by using the software to input the operation information, the operator can easily grasp the setting status visually. Furthermore, according to the configuration including the software, it is possible to generate a serial control signal to be sent to the power supply unit with a configuration that is much simpler than the hardware configuration such as a logic circuit.
