Magnetic Induction Electronic Go Technical Field
[0001] This invention relates to the field of electronic Go boards, and particularly to magnetic induction electronic Go boards. Background Technology
[0002] There are two main types of existing magnetic induction Go boards:
[0003] The first type uses linear Hall effect chips in a magnetic induction Go board. These chips are independent and cannot be connected in series or parallel, resulting in an extremely complex circuit with numerous components. The MCU must also have AD functionality. For example, the technical solution with publication number 107261477A and invention patent application titled "Intelligent Go Based on Magnetic Induction" includes a power supply system, a microprocessor, a Hall effect identification matrix composed of 361 Hall effect elements, and an LED display matrix. Each Hall effect element needs to be connected to the microprocessor's I / O port, requiring a total of 361 I / O ports. This technical solution uses a scanning method of the Hall effect identification matrix: "First, the microprocessor initializes, then activates each row of Hall effect elements, scans the output of the activated row of Hall effect elements, and determines whether the output is 0. If the output is 0, the Hall effect element output for that row indicates no Go piece has been placed, and the number is recorded. If the output is not 0, the Hall effect element output for that row indicates a Go piece has been placed, and the number is recorded. Then, the next row of Hall effect elements is scanned to determine whether there is an LED to display. If there is an LED..." If a display is required, the changing LED will be displayed; otherwise, proceed to the next step. Finally, it checks if there is data on the Bluetooth serial port. If there is data, the upper computer command data is obtained according to the custom protocol, and the corresponding response data is returned. Then, it loops back to the initial step. If there is no data on the Bluetooth serial port, the microprocessor loops back to the initial step. This can reduce the number of I / O ports required to some extent, but multiple microprocessors are still needed to provide I / O ports. The circuit structure is complex, with too many I / O ports and leads, resulting in high production costs and reduced circuit stability. Furthermore, this technical solution requires a dual-board PCB layout, and the circuit connections between the boards require vias and jumpers. Also, because the connection between the multiple linear Hall effect chips and the microprocessor is neither series nor parallel, the PCB layout is extremely complex.
[0004] The second type is a magnetic induction Go board that can connect 361 magnetic induction integrated circuit chips in series. If one of the magnetic induction integrated circuit chips fails, the other Go pieces cannot be used normally and are easily damaged. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings and deficiencies of the prior art and provide a magnetic induction electronic Go board.
[0006] The objective of this invention is achieved through the following technical solution:
[0007] The magnetic induction electronic Go board includes a PCB, a Go board, black Go stones, and white Go stones; the PCB is equipped with an MCU and several magnetic induction integrated circuit chips with address codes; the magnetic induction integrated circuit chips are all positioned directly below the cross center of the Go board's placement points, and the black and white Go stones contain magnetic components.
[0008] The magnetic induction integrated circuit chip includes power supply pins, ground pins, and data pins; 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 pins are connected in parallel to share the data line network DIO, which is connected to the MCU; data information is transmitted on the data line network DIO.
[0009] The magnetic induction electronic Go board includes a PCB, a Go board, black Go stones, and white Go stones; the PCB is equipped with an MCU and several magnetic induction integrated circuit chips with address codes; the magnetic induction integrated circuit chips are all positioned directly below the cross center of the Go board's placement points, and the black and white Go stones contain magnetic components.
[0010] 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 a power network VCC, and the ground pins are connected in parallel to share a ground network GND; data information is modulated on the power network VCC for transmission.
[0011] The magnetic induction integrated circuit chip has an address code and is programmable. In practical applications, it can save the natural number sequence of the chessboard as a communication address code.
[0012] The magnetic induction integrated circuit chip also integrates a GRB color 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 polarity direction.
[0014] The magnetic induction integrated circuit chip is programmable at its N and S poles, at which point the magnetic elements inside the black and white chess pieces have opposite polarities.
[0015] The chessboard is either a detachable chessboard or a folding chessboard.
[0016] A metal element that attracts the magnetic element is placed below the chessboard's placement point.
[0017] The MCU of the magnetic induction electronic Go game transmits the player's move information or key operation information 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 game with address code of this invention connects all 361 Go positions in parallel through only one data line, greatly reducing the number of circuit components and giving it a good cost advantage; the magnetic induction integrated circuit chips with address code are independent of each other, so the failure of one will not affect the other, thus ensuring high reliability.
[0022] 2. The magnetic induction integrated circuit chip Go game with address code of the present invention modulates the data information onto the power supply for transmission. Compared with the chip with data line, the circuit is simpler, has fewer circuit components, and has a better cost advantage.
[0023] 3. This invention's magnetic induction integrated circuit chip Go board with address code features built-in RGB lighting, enabling various prompts on the board, Go position recall, and enhanced AI connectivity. Furthermore, the lighting is perfectly centered directly below the crosshair at each move point, resulting in a superior user experience. In contrast, the technical solution with application publication number 107261477A requires additional lighting circuitry, preventing the lighting from being perfectly centered on the move point, leading to a more complex and aesthetically unappealing circuit.
[0024] 4. This invention provides a magnetic induction integrated circuit chip for Go with address codes. It utilizes different induction polarities to represent three states of a Go piece at the same position: state 0 (no piece), state 1 (white piece), and state 2 (black piece). This is a standard ternary state element. Compared to the analog output of a linear Hall effect sensor, this invention provides a digital change quantity and a digital ternary state element. It eliminates the need for a linear magnetic induction chip with analog output and a dedicated MCU with AD converter. It offers high reliability and simple circuit design.
[0025] 5. This invention relates to a magnetic induction integrated circuit chip Go game with address codes. By using different BOP settings of the magnetic induction integrated circuit chip, it completes three states of Go at the same position: state 0 with no stones, state 1 with white stones, and state 2 with black stones. It is a standard ternary state element. Compared with the analog output of linear Hall effect sensors, this invention is a digital change quantity, a digital ternary state element. It does not require a linear magnetic induction chip with analog output, nor does it require an MCU with AD converter. It has high reliability and simple circuit design.
[0026] 6. The magnetic induction integrated circuit chip Go game of the present invention with address code, since the magnetic induction integrated circuit chips with address code are connected in parallel, can be naturally made into a separate or foldable Go game, making it more convenient to carry.
[0027] 7. This invention relates to a magnetic induction integrated circuit chip Go game with address codes. Different shaped magnetic elements can be placed at the center of each Go piece, allowing the pieces to return to their original positions after being placed. This results in a more uniform arrangement of the Go pieces, improving the user experience and visual appeal. The pieces can also be hung up for demonstration purposes without falling off.
[0028] 8. The connection between the multiple magnetic induction integrated circuit chips with address codes and the MCU in this invention is in parallel. The PCB only needs a single board to complete the wiring and circuit design, without jumpers and vias, making the manufacturing process simpler and the cost lower. Attached Figure Description

[0036] 21-First magnetic element. Detailed Implementation
[0037] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto. Example 1
[0038] As shown in Figure 1, the magnetic induction electronic Go board includes a PCB, a Go board, black Go pieces, and white Go pieces; the PCB is equipped with an MCU and several magnetic induction integrated circuit chips with address codes; the magnetic induction integrated circuit chips are all positioned directly below the cross center of the Go board's placement points, and the black and white Go pieces contain magnetic components.
[0039] The magnetic induction integrated circuit chip includes power supply pins, ground pins, and data pins; 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 pins are connected in parallel to share the data line network DIO, which is connected to the MCU; data information is transmitted on the data line network DIO.
[0040] Figure 1 shows only 3 magnetic induction integrated circuit chips with address codes. The entire magnetic induction electronic Go board can connect the power supply pins of 361 integrated circuit chips in parallel to share the power supply network VCC, the ground pins in parallel to share the ground network GND, and the data line pins in parallel to share the data line network DIO to connect to the MCU. Data information is transmitted on the data line network DIO.
[0041] As shown in Figure 2, the 361 magnetic induction integrated circuit chips are arranged from left to right in the coordinate system as sequence 1, sequence 2, sequence 3... sequence 361. The first magnetic element 21 moves above each magnetic induction integrated circuit chip in a custom sequence from beginning to end. When the first magnetic element 21 moves above the sequence 1 magnetic induction integrated circuit chip, the sequence 1 magnetic induction integrated circuit chip senses a voltage change through magnetic induction. Simultaneously, the sequence 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. Next, when the first magnetic element 21 moves above the sequence 2 magnetic induction integrated circuit chip, the sequence 2 magnetic induction integrated circuit chip senses a voltage change through magnetic induction. Simultaneously, the sequence 2 magnetic induction integrated circuit chip receives an address code instruction and address code 2, and then... Then, the number 2 is saved as the address code. Next, when the first magnetic element 21 moves above the sequence 3 magnetic induction integrated circuit chip, the sequence 3 magnetic induction integrated circuit chip senses the voltage change through magnetic induction. At the same time, the sequence 3 magnetic induction integrated circuit chip receives an address code allocation instruction and address code 3, and then saves the number 3 as the address code. By doing so, the programming of the sequence 1, sequence 2, sequence 3... sequence 361 magnetic induction integrated circuit chips with regular natural number sequence address codes is completed, forming 361 magnetic induction integrated circuit chips with natural number sequence positions as communication address codes. Using natural number sequence positions as communication address codes greatly facilitates information communication.
[0042] Furthermore, each magnetic induction integrated circuit chip with an address code also has its own UID (User ID) identification code. When the first magnetic element 21 acts on the magnetic induction integrated circuit chip with the address code, it first reads the chip's UID code, and then returns the UID code and address code together to the chip. The chip compares its own UID code; if they match, it correctly saves the address code; otherwise, it does not write it. This greatly improves the reliability of writing the address code.
[0043] The board of the magnetic induction electronic Go game has 361 move placement points, corresponding to 361 magnetic induction integrated circuit chips with address codes; as shown in Figure 3, 361 magnetic induction integrated circuit chips with address codes are connected in parallel to form a whole column, constituting 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 items with the same network name are electrically connected together.
[0044] The BOP and BRP of the magnetic induction integrated circuit chip are programmable, and at this time, the magnetic elements in the black Go piece and the white Go piece are in the same polarity direction. That is, the magnetic elements in the black and white Go pieces are all in the N pole direction or all in the S pole direction.
[0045] The corresponding magnetic elements in the black and white Go pieces are in the same polarity direction, and the magnetic magnitudes of the magnetic elements in the black and white Go pieces are different, with one side necessarily having a greater magnetism than the other. At this time, BOP is set to values A and B, assuming A<B, the magnetic field strength of the magnetic element in the black Go piece is greater than that of the magnetic element in the white Go piece and can trigger the B value of BOP, while the magnetic element in the white Go piece can only trigger the A value of the magnetic field strength BOP and cannot trigger the B value. By utilizing the different magnetic field strengths of the magnetic elements and setting the two BOP values A and B of the magnetic induction integrated circuit chip, three states of the Go piece at the same position are completed, namely the state O with no piece, the state 1 with a white Go piece, and the state 2 with a black Go piece, forming a standard ternary state element.
[0046] Alternatively, the N and S poles of the magnetic induction integrated circuit chip are programmable, and at this time, the polarities of the magnetic elements in the black Go piece and the white Go piece are opposite.
[0047] If the magnetic element in the black Go piece is an N pole, the magnetic element in the white Go piece must be an S pole; when the magnetic induction integrated circuit chip is programmed for N pole induction, the sensed piece must be a black Go piece, and when the magnetic induction integrated circuit chip is programmed for S pole induction, the sensed piece must be a white Go piece. This method of utilizing different polarities also achieves three states of Go at the same position, namely the state O with no piece, the state 1 with a white Go piece, and the state 2 with a black Go piece, forming a standard ternary state element.
[0048] Similarly, if the magnetic element in the black Go piece is an S pole, the magnetic element in the white Go piece must be an N pole, and the principle is the same, which will not be repeated.
[0049] The board is a separable board or a foldable board. Since the magnetic induction integrated circuit chips of the magnetic induction electronic Go game are connected in parallel, the Go board can naturally be made into a separable board, split into two parts, three parts, four parts, etc.; or the Go board can be made into a foldable board, such as a two-fold, three-fold, or four-fold board.
[0050] The chessboard has metal components below the placement points that attract magnetic elements. This allows the Go stones to return to their original positions after being placed, resulting in a uniform arrangement and a better user experience. The stones can also be hung up for demonstrations without falling.
[0051] The MCU of the magnetic induction electronic Go game transmits the player's move information or key operation information to the terminal device via a wired / wireless transceiver module. The terminal device includes a computer and a mobile terminal.
[0052] The magnetic induction integrated circuit chip is a unipolar magnetic induction integrated circuit chip.
[0053] The unipolar magnetic induction integrated circuit chip includes a unipolar Hall chip, and unipolar magnetoresistive chips AMR, GMR, and TMR.
[0054] 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 button's on / off travel can be set; the magnetic induction polarity of the magnetic induction integrated circuit chip is also programmable.
[0055] BOP stands for Operating Point, which refers to the minimum magnetic field strength required for a Hall switch to begin conducting under magnetic influence.
[0056] BRP stands for Release Point, which refers to the maximum magnetic field strength at which a Hall switch closes under magnetic influence.
[0057] To ensure the normal operation of magnetic induction integrated circuit chips, the BOP value is usually set to be greater than the BRP value. Example 2
[0058] Example 2 is identical to Example 1 except for the following content:
[0059] The magnetic induction electronic Go board includes a PCB, a Go board, black Go stones, and white Go stones; the PCB is equipped with an MCU and several magnetic induction integrated circuit chips with address codes; the magnetic induction integrated circuit chips are all positioned directly below the cross center of the Go board's placement points, and the black and white Go stones contain magnetic components.
[0060] 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 a power network VCC, and the ground pins are connected in parallel to share a ground network GND; data information is modulated on the power network VCC for transmission.
[0061] In other words, the magnetic induction integrated circuit chip in Example 2 only requires a power network and a ground network. Data information is modulated on the power network for transmission, eliminating the need for a data line network (DIO). This further reduces the number of pins and leads in the magnetic induction integrated circuit chip, making the circuit simpler.
[0062] The magnetic induction integrated circuit chips in Examples 1 and 2 can also integrate GRB RGB driving circuits. With RGB functionality, black and white chess pieces can be partially transparent, and RGB lighting on the chessboard can provide various prompts, including a Go position recall function. Connecting to AI further enhances this functionality.
[0063] Meanwhile, a ring-shaped metal element can be set around the magnetic induction integrated circuit chip. After the black / white chess piece is placed, the magnetic force attracts the piece to the center of the placement point, and the RGB light shines from the hollow part of the ring-shaped metal element onto the transparent part of the black and white chess piece without obstruction.
[0064] At this point, the working process of the magnetic induction electronic Go board is as follows:
[0065] First, set the magnetic parameter information (as shown in Figure 4, the data information for executing the write command includes position information + magnetic parameter information); the position information is the sequence information of the magnetic induction integrated circuit chip; the magnetic parameter information includes whether the magnetic induction integrated circuit chip is BOP or BRP programmable and the BOP value and BRP value, or whether the magnetic induction integrated circuit chip is N-S pole programmable.
[0066] Then, read the status information (as shown in Figure 6, the data information for executing the read command includes position information + status information); there are three types of status information: none, black piece, white piece;
[0067] Finally, color information is set based on the status information (as shown in Figure 5, the data information for executing the write command includes position information + color information); the color information includes color grayscale information. Up to twice the number of chips with color-changing functionality can be placed on the chessboard to form an LED matrix, displaying better patterns and creating a more harmonious atmosphere for the Go game.
[0068] 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 changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
