Abstract

Detectors are provided under the intersections on a go board so as to detect a stone placed on an intersection, making a distinction between white and black stones. Data on the record is generated according to the information on the detection by the detectors every time either of the stone-placement switches arranged for the white player and black player and operated after either of the players places a stone is operated. Thus, the record can be displayed on a screen according to the data on the go record during or after the game or printed out.

Description

Specification

Go stone detection device and go system

The present invention relates to an apparatus for distinguishing black stones from white stones and detecting the start of a go stone on a go board, and a go system capable of automatically generating and processing game record data while detecting the go stones.

In order to improve the performance of Go, it is necessary to rearrange the procedures of the game played by oneself in the past or the game records of other high-ranked players (generally professional chess players).

However, it would be possible to reproduce the game through a PC screen such as the Internet.In a normal game on a go board, it would be impossible for a professional shogi player to leave a game record in his or her own game. It is practically difficult.

The present invention provides a Go system and a Go system that can automatically generate game record data during a game using a full-fledged go board and can easily arrange go stones based on the game data. It is an object of the present invention to provide a go stone detection device used for a vehicle.

In order to achieve the above object, a go stone detection device according to the present invention includes:

A detection coil and a drive coil arranged below each grid of the go board main body;

Energization control means for variably controlling the energization current to each drive coil below each of the grids,

When the energization control means changes the energizing current to the previous isi-moving coil, the level of the electromotive force induced in the detection coil changes when the goishi is not placed on the corresponding grid and when the black stone is placed. Black stone and white stone, which are made of different materials so that they are different when the stone is placed and when the stone is placed,

Detecting means for distinguishing and detecting black stone and white stone on each grid according to the level of the electromotive force induced in the detection coil when the current supplied to each of the drive coils changes by the current control means;

Is characterized by including. With such a configuration, the energization control means variably controls the energization current to each horse driving coil below each grid, and when the energization current changes, no go stone is placed on each grid. Since the level of the electromotive force induced in the horse coil differs between when the black stone is placed and when the white stone is placed, these states can be distinguished and detected. Black stones and white stones on each grid can be detected separately. For example, one of the black stone and the white stone may be formed of a magnetic material, and the other may be formed of a non-magnetic metal.

In this way, when the drive current to the moving coil changes, for example, when the rectangular pulse current changes from OFF to ON and from ON to OFF, an electromotive force is induced in the detection coil. Specifically, when changing from OFF to ON, an electromotive force is induced in the direction in which current flows in the opposite direction to the drive current, and when changing from ON to OFF, current flows in the same direction as the drive current. A directional electromotive force is induced.

When the electromotive force induced in the detection coil without the go stone is taken as the reference level, when the go stone formed of the magnetic material is placed, the coupling coefficient increases due to the magnetic material. The generated electromotive force is higher than the reference level.

When a go stone formed of a nonmagnetic metal is placed, an electromotive force in the same direction is also induced in the nonmagnetic metal go stone by the same principle as that of an electromotive force in the detection coil. Since the detection coil is sandwiched between the drive coil and the go stone, the directions of the current flowing through the drive coils on both sides and the current flowing due to the electromotive force induced by the go stone are opposite to each other. Therefore, the electromotive force induced in the detection coil decreases below the reference level.

As described above, since the level of the electromotive force induced by the detection level is different, it is possible to detect the goishi on each of the grids by distinguishing between the black stone and the white stone.

Here, for example, the magnetic material can be ferrite.

In this case, since the ferrite is not a conductor, no electromotive force is induced in the ferrite itself, and the electromotive force of the detection coil is not canceled. Accordingly, the level of the electromotive force in each of the above-mentioned states greatly differs, and the detection accuracy can be improved.

Also, for example, the magnetic metal can be aluminum or copper.

In this case, since aluminum or copper is a good conductor, the induction induced in the detection coil A large electromotive force that offsets and reduces the power is generated. Accordingly, the level of the electromotive force in each of the above-mentioned states greatly differs, and the detection accuracy can be improved.

Further, the detection coil and the drive coil may be spirally formed on the same plane so as to be alternately adjacent to each other.

The detection coil and the drive coil can be spirally wound on a cylindrical surface and arranged vertically, but the thickness increases. Therefore, by forming a spiral shape on the same plane so as to be adjacent to each other alternately as described above, it is possible to make the detection coil and the drive coil on a single film as thin as possible using a coil. The induction action between them increases, the number of parts and the number of assembly steps can be reduced, and the cost can be reduced.

Further, the Go system according to the present invention includes:

A detection coil and a drive coil arranged below each grid of the go board main body; an energization control means for variably controlling an energization current to each drive coil below each grid; and a drive coil by the energization control means. When the level of the electromotive force induced in the detection coil at the time of the change of the energizing current is not placed on the corresponding grid of the go board body, when the black stone is placed, and when the white stone is placed According to the black stone and the white stone formed of different materials so as to be respectively different from each other, and according to the level of the electromotive force induced in the detection coil when the current supplied to each of the drive coils by the current control means changes. Detecting means for distinguishing between when a black stone is placed on each of the grids and when a white stone is placed, and a go-stone detecting device comprising:

Game record data generating means for generating game record data based on information from the go stone detection device;

Is characterized by including.

With such a configuration, the black stone and the white stone on each of the grids can be separately detected by the go stone detection device having the function described in claim 1 above. The game record data generating means generates the game record data.

Further, another Go system according to the present invention includes:

A go-stone detection device for detecting go-stones on the grid of the go board body by distinguishing between black stone and white stone; Starting switches for black and white that are manually operated,

Based on information from the starting switch and the go stone detecting means, a game data generating means for generating game data;

Is characterized by including.

With such a configuration, when the start switch is operated, the go stone is detected and the game record data is updated, so that even if the go stone is dropped or the position of the go stone is shifted, the data is corrected in a correct state. Has been updated, and the game record can be created accurately. Also, when displaying the game record data on the screen or print, there is a rule that the black number is on the lower side and the white number is on the upper side, but it is not known which side the black number or white number sits on the go board, so It is not possible to distinguish between black and white by simply detecting black stone and white stone.However, with the start switch, black and white can be distinguished and black can be displayed on the lower side and white can be displayed on the upper side. .

In addition, as the go stone detection device of the Go system, a device that distinguishes and detects black stone and white stone based on the electromotive force level can be used.

Further, in these Go systems, a game record data storage means for storing the generated game record data may be included.

According to the configuration of the game, after the game is over, the game record can be reproduced based on the stored game data, and the game can be thoroughly studied. In particular, the game record can be reproduced at any time if it is stored in a removable memory such as a floppy disk.

Further, the game record data may be generated such that go stones are arranged and displayed in a wearing procedure on a grid on a screen.

According to such a configuration, the go stones are displayed side by side in the same manner as in the actual battle, so that it is easy to understand and the examination is easy. Also, by using this method, you can watch the game in real time on the screen.

The game record data may include a display means for displaying an image of the game record data on a screen and a print means for displaying a print.

That is, in general, an existing personal computer, television, or printer may be used for screen display or printing, but a system in which simple display means such as liquid crystal or a printer is set may be used. <Brief description of drawings>

Hereinafter, embodiments of the present invention will be described.

FIG. 1 shows an external view of a Go system according to an embodiment, in which a go board body 1 provided with a control circuit including a go stone detection switch described later, a black stone made of a δ 兹 -type body, a non-magnetic metal And two operation buttons that are connected to the control circuit of the go board body 1 and that are manually operated alternately in black and white for each start. Starting switch 3, a personal computer 4 connected to the control circuit of the go board body 1, a printer 5 connected to the computer 4, a control circuit of the go board body 1, a personal computer 4, a printer 5, etc. And a switch operation panel 6 having a power switch.

The board surface of the go board body 1 has 19 paths each in the vertical and horizontal directions, and a force of 19 x 19 to form a total of 36 1 eyes (go grid). An electronic component and an electrical component are mounted, and a connector (not shown) for connecting the starting switch 3, the personal computer 4, and the switch operation panel 6 is formed on a side surface or a lower surface.

FIG. 2 schematically illustrates a vertical cross section of each of the grids of the grid body 1. In the figure, a film 12 in which spirals are formed on the same plane so that a detection coil 11 する and a drive coil 11 B constituting the go stone detector 11 are alternately adjacent to each other below each grid. Will be arranged. The detection coil and drive coil can also be arranged vertically in a spiral shape wound on a cylindrical surface.If formed on a single film as described above, it can be made as thin as possible. And the induction between the coils also increases, The number of parts and the number of assembly steps can be reduced, and the cost can be reduced.

FIG. 3 shows a circuit configuration of the entire system including a circuit unit mounted inside the go board main body 1 and a circuit unit used in the personal computer 4. In the figure, a detector group 31 is a group of the above-mentioned goishi detectors 11 for 36 1 stitches. From the switch group 31, a predetermined number of strobe lines (for example, when there are 19 strobe lines, 36 1/19 = 19) are taken out, and the interface It is connected to the data processing section 33 through the circuit 32. The data processing unit 33 is further connected with an operation unit 34 (including the start switch 3 and the switch operation panel 6 in FIG. 1) via the interface 34. The data processing unit 33 is composed of, for example, a microcomputer, and determines whether or not there is a goishi for all the grids based on the signal level of each signal line from the detector group 31 as shown in FIG. They are detected separately. The memory 36 is used for such control.

FIG. 5 shows a specific configuration example of the switch group 31. 19 detection coils corresponding to the 19 grids arranged in tandem.11.Detection wires DET with 1 A connected in series are arranged in rows corresponding to the 19 grids. You. On the other hand, 19 drive coils 11 corresponding to 19 grids arranged in a row are connected in series. 19 drive coils DV are connected in series. Is done.

A drive circuit 41 for outputting a rectangular drive current to each of the drive lines DV 1 to DV 19 is connected to each end of each of the drive lines 0 1 to 0 19. On the other hand, an amplifier 42 is connected to each end of each of the detection lines DET1 to DET19, and the output of the amplifier 42 is input to the + terminals of the two comparators 43 and 44. . Different judgment voltages E 1 and E 2 (E 1> E 2) obtained by dividing the reference voltage by the resistors 45 and 46 are input to one terminal of the comparators 43 and 44. The output terminals of the comparators 43 and 44 are connected to a determination circuit 47, and the drive signals from the respective drive circuits 41 are input to the determination circuit 47. Then, when a driving signal is input from one of the nineteen driving circuits 41, a black stone is displayed on a grid to be detected based on a combination of outputs of one of the comparators 43 and 44. The state where the stone is placed, the state where the white stone is placed, and the state where the go stone is not placed are determined.

A series of go-stone detection operations will be described. Nine drive lines 0 1 to 1) Output rectangular drive current sequentially to ¥ 19. At this time, the nineteen detection coils 11A arranged corresponding to the drive coils 11B on each drive line DVn have a drive current flowing through the drive coil 11B from 0FF to 0N. When the current changes to ON and when the current changes from ON to OFF, an electromotive force is induced in the detection coil 11A according to the change in the current.

Here, with respect to the reference level of the electromotive force induced in the detection coil 11 A below the grid where no go stone is placed, the electromotive force induced in the detection coil 11 A below the grid where the black stone is placed And the level of the electromotive force induced in the detection coil 11 A below the grid on which the white stone is placed is reduced. In other words, if black stone made of fluorite, which is a magnetic material, is present above the detection coil 11A, the coupling coefficient is increased by the magnetic material, and the electromotive force level is increased. On the other hand, if there is white stone made of nonmagnetic metal, aluminum or copper, above the detection coil 11 A, an electromotive force is induced in the white stone as well as the detection coil 11 A, and the current flowing due to this electromotive force Is different from the direction of the drive current flowing through the drive coil 11B. Therefore, the electromotive force induced in the detection coil 11A by the drive current is offset by the electromotive force induced in the detection coil 11A by the current flowing in the white stone in different directions, and the level of the electromotive force is reduced.

Then, as shown in FIG. 5, when the drive pulse changes from 〇N to OFF while the black stone is placed, the level of the positive electromotive force (hereinafter the same) generated in the detection coil 11A depends on the level. The output voltage generated in the amplifier 42 is higher than the determination voltage E 1, and the output voltage generated in the amplifier 42 is lower than the determination voltage E 2 due to the level of the electromotive force in the state where the white stone is placed; The determination voltages El and E2 are set so that the output voltage generated in the amplifier 42 is higher than E2 and lower than E1 according to the level of the electromotive force when no go stone is placed. Thus, when the black stone is placed on the grid, the outputs of the comparators 4 3 and 4 4 are both high level, and when the white stone is placed on the grid, the outputs of the comparators 4 3 and 4 4 are output. Are low level, and when no go stones are placed on the grid, the output of the comparator 43 becomes a high level and the output of the comparator 44 becomes a singular level. By using 47, these states can be determined. In this manner, the drive line is determined based on the timing of outputting the horse pulse on each drive line DVn and the determination result of each determination circuit 47 connected to the detection lines DET1 to DET19. Go stones on the grid on DV n can be detected by distinguishing black stones from white stones. Then, when the drive lines 01 to 019 are driven and scanned once, it is possible to know the stones of all the grids.

Next, the operation of the data processing unit 33 in FIG. 3 will be described. Each time the start switch 3 is operated in correspondence with the black turn and the white turn after the start, the data processing section 33 performs a horse scan dynamic scanning of the drive lines DV 1 to DV 19, and Go stones are detected separately from black stones and white stones, and the results of the previous and present detections are compared, and the classification of black stones and white stones, position data, and “stones are placed” and “stones are removed” The game data is generated based on the data of "ta", and the order is added, and then stored in the memory 36.

Here, since the game record data is updated by operating the start switch 3, even if the go stones are dropped or the go stones are misaligned, the data is updated with the correct condition. , You can create a game record accurately.

In order to reproduce the game record created in this way, the display drive unit is controlled based on the game record data, and sequentially displayed on the screen of the personal computer 4. When displaying the game record on the screen or print, there is a rule that the black number is on the lower side and the white number is on the upper side, so the black number and the white number are distinguished based on the signal from the start switch 3. The black incense is displayed on the bottom and the white one on the top.

In this way, since the game record data is stored in the memory 36, the game data can be read out from the memory 36 and reproduced after playing, so that it can be thoroughly studied. Needless to say, it is possible to easily provide a pause function and a return function. In addition, it is of course possible to display on the screen in real time based on the output of the data processing section 33, and a third party (eg, commentator) can watch the game at a place away from the player. In particular, it is possible to watch multiple games simultaneously on a large screen or switch screens by processing on the personal computer side, and it is possible to watch a game at a Go competition where many people participate. (E.g., it is also possible to set up a personal computer on the player side and the instructor to provide mutual communication guidance using a chat, etc.). Since no equipment is required, operating costs can be reduced.

After the game is over, you can print out the game record data on the printer 5. You. As the display in the print, similarly to the display in the publication, the grid may be indicated by coordinates (such as 1), or a stone on the grid may be displayed with a start number attached. . Users will be pleased if they can return the print of the game record data after the game ends at the Gokaisho.

In addition, the game data can be stored in a removable memory such as a floppy disk, and can be reproduced at a later date, and the game data can be managed and stored. In the case of a lot of games such as qualifying for the Go competition, a self-service system is used in which players record the game data on a floppy disk or the like and submit the printed game record after the game is over. And you don't need to have a clerk. In the circuit of the entire system shown in FIG. 3, the switch group 31 must be provided on the power of the go board 1, and the data processing section 33 and the memory 36 must be provided on the go board 1 side. However, when the data processing section 33 and the memory 36 are provided on the go board 1 side, the connection with the computer 4 is unnecessary when the screen display during the game is not desired. Also, if the game record data is output as a video signal, it can be connected to the video terminal of the TV instead of the PC 4 for playback. Further, if the memory such as the floppy disk is detachable from the go board main body 1, the reproduction can be performed only by the personal computer 4. On the other hand, even when the data processing unit 33 and the memory 36 are provided on the personal computer 4 side, the data processing unit 33 is composed of programs stored on a floppy disk, CD, etc. in order to use an existing personal computer. Good to do. If a battery (preferably a rechargeable battery) can be used as the power source, and if the starting switch 3 is wirelessly transmitted to the circuit in the main body 1 of the board, the wiring from the board is eliminated and the appearance is good. Each player may have a black remote control switch and a white remote control switch.

In addition, the start switch 3 can incorporate a game clock for measuring the start time for each of the black and white players used for the game with time restrictions, and the clock can be displayed on the screen of the personal computer 4. In addition, the starting switch and the switch operation panel can be integrated, and further, these operation switches can be provided on the go board main body 1 to achieve compactness.

In addition, as described above, the provision of the starting switches for black and white Not only can the staff data be accurately created, and the black numbers can be displayed on the bottom and the white numbers on the top can be displayed reliably, so it can be used for formal games. A system without a switch can also be provided. With this method, it is not guaranteed that an accurate game record will be created and saved if the go stone is dropped or the go stone is misaligned, but the go stone detector detects black stone and white stone separately. In addition, since the display in real time can be performed accurately, especially when there is no need to create and save an accurate game record, this can be done in time, and the examination of the go game can be performed without any problem. In addition, accurate display is not guaranteed for black display on the lower side and white display on the upper side, but in general, the first start of the black display is often on the side closer to the white display. By displaying it, it can be displayed almost correctly. (However, in order to display correctly even in Go, it is necessary to put the first black stone on the side near the white number ^).

As described above, the present invention can be used not only for amateur go lovers but also for professional chess players, and can be widely used in competitions and go classrooms where many people play games. , Which greatly contributes to the game console industry.
