Description

Technical Field

[0001] The present invention relates to the field of electronic Go boards, and particularly to magnetic induction electronic Go. Background Art

[0002] There are mainly two types of existing magnetic induction Go boards:

[0003] First, the magnetic induction Hall chips of the magnetic induction Go board are linear Hall chips and are used independently of each other. They cannot be connected in series or in parallel. The circuit is extremely complex, with many components, and the MCU must also have an AD function. For example, in the technical solution of the patent application publication number 107261477A, the invention patent application named "Intelligent Go Based on Magnetic Induction", which includes a power supply system, a microprocessor, a Hall element identification matrix composed of 361 Hall elements, and an LED display matrix; each Hall element needs to be connected to the IO port of the microprocessor, and a total of 361 IO ports are required. This technical solution "first initializes the microprocessor, respectively turns on each row of Hall elements, scans the output of the turned-on Hall elements in this row, and judges whether the output is 0. If the output is 0, it means that there is no Go placed in this row of Hall elements, and this number is recorded. If the output is not 0, it means that there is Go placed in this row of Hall elements, and this number is recorded; then scans the next row of Hall elements, judges whether there is an LED that needs to be displayed. If there is an LED that needs to be displayed, the changed LED is displayed. If there is no LED that needs to be displayed, go to the next step; finally, judge whether there is data in the Bluetooth serial port. If there is data in the Bluetooth serial port, obtain the host computer command data according to the custom protocol and return the response data corresponding to the host computer command, and then loop back to the initial step. If there is no data in the Bluetooth serial port, the microprocessor loops back to the initial step", which can reduce the required number of IO ports to a certain extent, but still requires multiple microprocessors to provide IO ports. The circuit structure is complex, the number of IO ports and leads is too large, the production cost is relatively high, and the circuit stability will be reduced; and the PCB wiring of this technical solution requires a double board, and the circuit connection between the boards requires vias and jumpers. At the same time, because the connection relationship between multiple linear Hall chips and the microprocessor is neither in series nor in parallel, the PCB wiring is extremely complex.

[0004] Second, 361 magnetic induction integrated circuit chips can be connected in series for the magnetic induction Go board. If one of the magnetic induction integrated circuit chips is damaged, the other Go pieces cannot be used normally and are easily damaged. Summary of the Invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a magnetic induction electronic Go.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0007] The magnetic induction electronic Go game includes a PCB, a chessboard, black chess pieces, and white chess pieces; an MCU and several magnetic induction integrated circuit chips with address codes are arranged on the PCB; the magnetic induction integrated circuit chips are respectively arranged directly below the centers of the cross-shaped chess-playing points on the chessboard, and the black and white chess pieces contain magnetic elements;

[0011] The magnetic induction integrated circuit chip has an address code and is programmable, and can save the natural number sequence defined by the chessboard as a communication address code in practical applications.

[0012] The magnetic induction integrated circuit chip also integrates a GRB color-changing driving circuit.

[0013] The magnetic induction integrated circuit chips BOP and BRP are programmable, and at this time, the magnetic elements in the black and white chess pieces are in the same polar direction.

[0014] The NS poles of the magnetic induction integrated circuit chips are programmable, and at this time, the magnetic elements in the black and white chess pieces have opposite polarities.

[0015] The chessboard is a separable chessboard or a foldable chessboard.

[0016] A metal element that attracts the magnetic element is arranged below the chess-playing point of the chessboard.

[0017] The MCU of the magnetic induction electronic Go game sends the chess-playing information or key operation information of the chess player to the terminal device through a wired / wireless transceiver module.

[0018] The magnetic induction integrated circuit chip is a unipolar magnetic induction integrated circuit chip.

[0019] The unipolar magnetic induction integrated circuit chip includes a unipolar Hall chip, and unipolar magnetoresistive chips AMR, GMR, and TMR.

[0020] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0021] 1. The magnetic induction integrated circuit chip Go of the present invention with address codes connects all 361 Go positions in parallel only through one data line, greatly reducing circuit elements and having good cost advantages; the magnetic induction integrated circuit chips with address codes are independent of each other, and if one is damaged, it does not affect the others, with good reliability.

[0022] 2. The magnetic induction integrated circuit chip Go of the present invention with address codes modulates data information onto the power supply for transmission. Compared with the chips with data lines, the circuit is simpler, with fewer circuit elements and better cost advantages.

[0023] 3. The magnetic induction integrated circuit chip Go of the present invention with address codes has a built-in magic color RGB function, which can use lights to perform various prompting functions on the chessboard, a Go position recall function, and the function of connecting the electronic Go to AI is more powerful. And the lights can be completely centered directly below the center of the cross at the piece placement point, with better use effects. For the technical solution with the application publication number of 107261477A, the lighting circuit needs to be designed additionally, resulting in the lights not being able to be completely centered at the piece placement point of the chessboard, the circuit being more complex and not beautiful.

[0024] 4. The magnetic induction integrated circuit chip Go of the present invention with address codes uses different induction polarities to complete three states of Go at the same position: the state O without a piece, the state 1 with a white piece, and the state 2 with a black piece, a standard ternary state element. Compared with the analog output of a linear Hall, the present invention is a digital variable, a digital ternary state element, does not require a linear magnetic induction chip with analog output, and even less requires an MCU with an AD, with strong reliability and simple circuit design.

[0026] 6. The magnetic induction integrated circuit chip Go of the present invention with address codes, since the magnetic induction integrated circuit chips with address codes are connected in parallel, can naturally be made into a separable or foldable Go, which is more convenient to carry.

[0027] 7.

[0037] The present invention will be further described in detail below in conjunction with the embodiments and the drawings, but the embodiments of the present invention are not limited thereto.

[0038] Embodiment 1

[0039] As Figure 1 , the magnetic induction electronic Go includes a PCB, a chessboard, black chess pieces, and white chess pieces; an MCU and several magnetic induction integrated circuit chips with address codes are arranged on the PCB; the magnetic induction integrated circuit chips are respectively arranged directly below the centers of the chess-playing points on the chessboard, and magnetic elements are arranged inside the black and white chess pieces;

[0040] The magnetic induction integrated circuit chip includes a power supply pin, a ground pin, and a data line pin; the power supply pins of several magnetic induction integrated circuit chips are connected in parallel to share the power supply network VCC, the ground pins are connected in parallel to share the ground network GND, and the data line pins are connected in parallel to share the data line network DIO and are connected to the MCU; data information is transmitted on the data line network DIO.

[0041] Figure 1 In it, only 3 magnetic induction integrated circuit chips with address codes are shown. For the entire magnetic induction electronic go, the power supply pins of 361 integrated circuit chips can be connected in parallel to share the power supply network VCC, the 361 ground pins are connected in parallel to share the ground network GND, and the 361 data line pins are connected in parallel to share the data line network DIO and are connected to the MCU. Data information is transmitted on the data line network DIO.

[0042] Such as Figure 2 , the 361 magnetic induction integrated circuit chips are numbered as sequence number 1, sequence number 2, sequence number 3... sequence number 361 magnetic induction integrated circuit chips from left to right in the coordinate system. The first magnetic element 21 will move from beginning to end above each magnetic induction integrated circuit chip according to the custom sequence position. When the first magnetic element 21 moves above the sequence number 1 magnetic induction integrated circuit chip, the sequence number 1 magnetic induction integrated circuit chip senses a voltage change through magnetic induction. At the same time, the sequence number 1 magnetic induction integrated circuit chip receives an address code instruction and address code 1, and then saves the number 1 as the address code; then, when the first magnetic element 21 moves above the sequence number 2 magnetic induction integrated circuit chip, the sequence number 2 magnetic induction integrated circuit chip senses a voltage change through magnetic induction. At the same time, the sequence number 2 magnetic induction integrated circuit chip receives an address code instruction and address code 2, and then saves the number 2 as the address code; again, when the first magnetic element 21 moves above the sequence number 3 magnetic induction integrated circuit chip, the sequence number 3 magnetic induction integrated circuit chip senses a voltage change through magnetic induction. At the same time, the sequence number 3 magnetic induction integrated circuit chip receives an assigned address code instruction and address code 3, and then saves the number 3 as the address code; and so on. In this way, the programming of the regular natural number sequence address codes for the sequence number 1, sequence number 2, sequence number 3... sequence number 361 magnetic induction integrated circuit chips is completed, forming 361 magnetic induction integrated circuit chips with natural number sequence as the communication address code. Using the natural number sequence as the communication address code greatly facilitates information communication.

[0043] Furthermore, the magnetic induction integrated circuit chip with an address code also has its own UID identity code. When the first magnetic element 21 acts on the magnetic induction integrated circuit chip with an address code, first read the UID code of the chip, and then return the UID code and the address code together and output them to the chip. The chip compares its own UID code. If they are the same, it correctly saves the address code; otherwise, it does not write. This can greatly improve the reliability of writing the address code.

[0044] The board of the magnetic induction electronic Go has 361 positions for placing stones, corresponding to 361 magnetic induction integrated circuit chips with address codes. For example, Figure 3 , the 361 magnetic induction integrated circuit chips with address codes are connected in parallel to form a whole column, forming a VCC network, a ground GND network, and a data line DIO network; the shared data line network DIO is finally connected to the MCU, and all the same network names are electrically connected together.

[0045] The magnetic induction integrated circuit chips BOP and BRP are programmable. At this time, the magnetic elements in the black and white stones are of the same polar direction. That is, the magnetic elements in the black and white stones are all N poles or all S poles in the same direction.

[0046] The corresponding magnetic elements in the black and white stones are of the same polar direction, and the magnetic magnitudes of the magnetic elements in the black and white stones are different. One side must have a greater magnetic force than the other side. At this time, set BOP to values A and B. Assume A < B. The magnetic field intensity of the magnetic element in the black stone is greater than that of the magnetic element in the white stone and can trigger the B value of BOP, while the magnetic element in the white stone can only trigger the A value of BOP for the magnetic field intensity and cannot trigger the B value. By using the different magnetic field intensities of the magnetic elements and setting the A and B values of the two BOPs of the magnetic induction integrated circuit chip, three states of the Go stones at the same position are completed: the state O without stones, the state 1 with white stones, and the state 2 with black stones, a standard ternary state element.

[0047] Or, the NS poles of the magnetic induction integrated circuit chips are programmable. At this time, the magnetic elements in the black and white stones have opposite polarities.

[0048] If the magnetic element in the black stone is an N pole, the magnetic element in the white stone must be an S pole; when the magnetic induction integrated circuit chip is programmed to sense the N pole, the sensed stone must be a black stone, and when the magnetic induction integrated circuit chip is programmed to sense the S pole, the sensed stone must be a white stone. By using the different polarities, three states of the Go at the same position are also completed: the state O without stones, the state 1 with white stones, and the state 2 with black stones, a standard ternary state element.

[0049] Similarly, if the magnetic element in the black stone is an S pole, the magnetic element in the white stone must be an N pole. The principle is the same and will not be elaborated.

[0050] The board is a split board or a folding board. Since the magnetic induction integrated circuit chips of the magnetic induction electronic Go are connected in parallel, the Go board can naturally be made into a split board, such as being divided into two, three, four, etc.; or the Go board can be made into a folding board, such as being folded in two, three, four, etc.

[0051] A metal element that can be attracted by a magnetic element is provided below the chess piece placement point on the chessboard. This enables the Go pieces to have a self-aligning function after being placed, making the overall placement of Go pieces more orderly and providing a better viewing and experiencing effect. The pieces will not fall off and can also be hung up for a demonstration of the game.

[0052] The MCU of the magnetic induction electronic Go transmits the chess-playing information or key operation information of the chess player to the terminal device through a wired / wireless transceiver module. The terminal device includes a computer and a mobile terminal.

[0053] The magnetic induction integrated circuit chip is a unipolar magnetic induction integrated circuit chip.

[0054] The unipolar magnetic induction integrated circuit chip includes a unipolar Hall chip, and unipolar magnetoresistive chips AMR, GMR, and TMR.

[0055] The magnetic parameters BOP and BRP code values of the magnetic induction integrated circuit chip are programmable. By setting the BOP and BRP code values, the conduction stroke and cut-off stroke of the key can be set; the magnetic induction polarity of the magnetic induction integrated circuit chip is programmable.

[0056] The meaning of BOP is: Operating Point, that is, the working point, which refers to the minimum magnetic field strength at which the Hall switch starts to conduct under the action of magnetism.

[0057] The meaning of BRP is: Release Point, that is, the release point, which refers to the maximum magnetic field strength at which the Hall switch closes under the action of magnetism.

[0058] To ensure the normal application of the magnetic induction integrated circuit chip, usually the BOP value is set greater than the BRP value.

[0059] Embodiment 2

[0060] Compared with Embodiment 1, Embodiment 2 is the same as Embodiment 1 except for the following differences:

[0061] The magnetic induction electronic Go includes a PCB, a chessboard, black chess pieces, and white chess pieces; an MCU and several magnetic induction integrated circuit chips with address codes are provided on the PCB; the magnetic induction integrated circuit chips are respectively arranged directly below the centers of the cross-shaped chess piece placement points on the chessboard, and magnetic elements are provided inside the black and white chess pieces;

[0062] The magnetic induction integrated circuit chip includes a power supply pin and a ground pin; the power supply pins of several magnetic induction integrated circuit chips are connected in parallel to share the power supply network VCC, and the ground pins are connected in parallel to share the ground network GND; the data information is modulated and transmitted on the power supply network VCC.

[0063] That is, for the magnetic induction integrated circuit chip in Embodiment 2, only a power supply network and a ground wire network are required. Data information is modulated and transmitted on the power supply network without the need for a data line network DIO. The number of pins and leads of the magnetic induction integrated circuit chip is further reduced, and the circuit is more concise.

[0064] The magnetic induction integrated circuit chips in Embodiment 1 and Embodiment 2 can also integrate a GRB color-changing driving circuit. When having the RGB function, the black and white chess pieces can be made partially transparent. RGB uses lights on the chessboard to perform various prompting functions, such as the function of recalling the positions of Go pieces. Connecting to AI makes this function even more powerful.

[0065] Meanwhile, a ring-shaped metal element can be arranged on the outer periphery of the magnetic induction integrated circuit chip. After a black chess piece / white chess piece is placed, magnetic attraction makes the chess piece located at the center of the placement point, and RGB lights irradiate the transparent part of the black and white chess pieces from the hollow part of the ring-shaped metal element without causing occlusion.

[0066] At this time, the working process of the magnetic induction electronic Go is as follows:

[0067] First, set magnetic parameter information (such as Figure 4 , the data information for executing the write command includes position information + magnetic parameter information); the position information is the sequence number information of the magnetic induction integrated circuit chip; the magnetic parameter information includes that the magnetic induction integrated circuit chip is programmable for BOP and BRP, and the BOP value and BRP value, or the magnetic induction integrated circuit chip is programmable for NS poles;

[0068] Then, read status information (such as Figure 6 , the data information for executing the read command includes position information + status information); there are three types of status information: none, black chess piece, and white chess piece;

[0069] Finally, set color information according to the status information (such as Figure 5 , the data information for executing the write command includes position information + color information); the color information includes color gray-scale information. Two times more chips with color-changing functions can be set on the chessboard to form an LED matrix, displaying better patterns to set off a better pattern atmosphere for Go.

[0070] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
