[0002] The existing magnetic induction go board mainly has two kinds:
[0003] The first kind, the magnetic induction hall chip of the magnetic induction go board is linear hall chip, and is used independently, cannot be connected in series or in parallel, the circuit is extremely complex, the components are many, and the MCU must also have AD function.For example, the technical scheme with the application publication number 107261477A and the utility model patent application name "intelligent go based on magnetic induction" includes a power supply system, a microprocessor, a hall element recognition matrix composed of 361 hall elements, and an LED display matrix; each hall element needs to be connected with the IO port of the microprocessor, and a total of 361 IO ports are needed, the technical scheme scans the hall element recognition matrix to "firstly initialize the microprocessor, turn on each row of the hall element, scan the output of the turned-on row of the hall element, judge whether the output is 0, if the output is 0, the output of the row of the hall element is no go, the number is recorded, if the output is not 0, the output of the row of the hall element is go, the number is recorded; then scan the next row of the hall element, judge whether the LED needs to be displayed, if the LED needs to be displayed, the changed LED is displayed, if the LED does not need to be displayed, the next step is entered; finally, judge whether there is data in the Bluetooth serial port, if there is data in the Bluetooth serial port, the host computer command data is obtained according to the self-defined protocol, and the corresponding response data of the host computer command is returned, and then the initial step is recycled, if there is no data in the Bluetooth serial port, the microprocessor is recycled to the initial step", which can reduce the number of IO ports required to a certain extent, but still needs multiple microprocessors to provide IO ports, the circuit structure is complex, the number of IO ports and lead wires is too large, the production cost is high, and the circuit stability is reduced; and the PCB wiring of the technical scheme needs double boards, the circuit connection between the boards needs a via and a jumper, and because the connection relationship between the multiple linear hall chips and the microprocessor is neither in series nor in parallel, the PCB wiring is very complex.
[0004] The second kind, the magnetic induction go board can be connected in series with 361 magnetic induction integrated circuit chips, if one of the magnetic induction integrated circuit chips is broken, other go pieces cannot be normally used, and are easy to be damaged. UTILITY MODEL CONTENTS

[0034] 21-First magnetic element. Detailed Implementation
[0035] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of the present invention is not limited thereto.
[0036] Example 1
[0037] like Figure 1 A 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.
[0038] 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.
[0039] Figure 1 In the middle, only 3 magnetic induction integrated circuit chips with address codes are displayed. 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.
[0040] like 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 chip, the sequence 1 chip senses a voltage change through magnetic induction and receives an address code instruction and address code 1, then saves the number 1 as the address code. Next, when the first magnetic element 21 moves above the sequence 2 chip, the sequence 2 chip senses a voltage change through magnetic induction and receives an address code instruction and address code 2, 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.
[0041] 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.
[0042] 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.
[0043] The magnetic induction integrated circuit chips BOP and BRP are programmable. At this time, the magnetic elements in the black and white stones are in the same polar direction. That is, the magnetic elements in the black and white stones are all in the N - pole or S - pole direction in the same direction.
[0044] The corresponding magnetic elements in the black and white stones are in the same polar direction, and the magnetic magnitudes of the magnetic elements in the black and white stones are different, and 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 stone at the same position are completed: the state O without a stone, the state 1 with a white stone, and the state 2 with a black stone, a standard ternary state element.
[0045] 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.
[0046] If the magnetic element in the black stone is the N - pole, the magnetic element in the white stone must be the S - pole; when the magnetic induction integrated circuit chip is programmed for N - pole induction, the stone sensed must be a black stone, and when the magnetic induction integrated circuit chip is programmed for S - pole induction, the stone sensed 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 a stone, the state 1 with a white stone, and the state 2 with a black stone, a standard ternary state element.
[0047] Similarly, if the magnetic element in the black stone is the S - pole, the magnetic element in the white stone must be the N - pole, and the principle is the same and will not be elaborated.
[0048] The board is an integral board or a separable 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 be naturally made into a separable board, divided into two, three, four, etc.; or the Go board can be made into a folding board, folded in two, three, four, etc.
[0049] 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.
[0050] 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.
[0051] 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.
[0052] BOP stands for Operating Point, which refers to the minimum magnetic field strength required for a Hall switch to begin conducting under magnetic influence.
[0053] BRP stands for Release Point, which refers to the maximum magnetic field strength at which a Hall switch closes under magnetic influence.
[0054] To ensure the normal operation of magnetic induction integrated circuit chips, the BOP value is usually set to be greater than the BRP value.
[0055] Example 2
[0056] Example 2 is identical to Example 1 except for the following content:
[0057] 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.
[0058] 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.
[0059] 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.
[0060] 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.
[0061] 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.
[0062] At this point, the working process of the magnetic induction electronic Go board is as follows:
[0063] First, set the magnetic parameter information (such as...) Figure 4 The data information for executing the write command includes position information and 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.
[0064] Then, read the status information (such as...) Figure 6 The data information for executing the read command includes location information and status information; there are three types of status information: none, black piece, and white piece;
[0065] Finally, set the color information based on the status information (e.g., Figure 5 The data information for executing the write command includes position information and 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 enhancing the overall atmosphere of the Go game.
[0066] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model 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 utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
