Description

Technical Field

[0001] This invention relates to the field of competitive and leisure entertainment, and in particular to an intelligent board game with magnetic ring pieces. Background Technology

[0002] Existing smart card and board games have various problems that are currently difficult to solve with technology.

[0003] For example, Chinese utility model patent CN214286658U discloses an intelligent chess and card game, including a chessboard and chess pieces. The chessboard is equipped with an electromagnetic antenna array, with each electromagnetic antenna corresponding to a placement point on the chessboard. Each chess piece contains an electromagnetic resonant device, and the resonant frequency of the electromagnetic resonant device in each piece is different. The intelligent chess and card game also includes a control circuit, which comprises a microcontroller, an electromagnetic transmitting module, an electromagnetic receiving module, and a signal switching circuit. The electromagnetic transmitting module is connected to the transmitting end of the microcontroller, and the electromagnetic receiving module is connected to the receiving end of the microcontroller. The electromagnetic transmitting and receiving modules are respectively connected to the signal switching circuit, which is connected to the electromagnetic antenna array. By transmitting the resonant frequency of each chess piece one by one through the electromagnetic antenna corresponding to each placement point, the positions of all the chess pieces on the board can be determined, and then tracked according to the progress of the game.

[0004] The above scheme has the disadvantages of large deviation of the placement position from the center, which can easily lead to misjudgment, complex structure and high cost, and easy interference with electromagnetic waves.

[0005] For example, Chinese invention patent application CN113476818A discloses an intelligent chessboard and a chess piece recognition method. The intelligent chessboard includes a chessboard body, a magnetic sensing module, a main control module, and a recognition module. The magnetic sensing module, main control module, and recognition module are built into the chessboard body. The magnetic sensing module includes several magnetic sensors. The chessboard grid has several chess piece positions, and a magnetic sensor is correspondingly placed below each chess piece position. There is at least one recognition module, capable of identifying the chess piece number associated with the intelligent chessboard. The main control module transmits data to both the magnetic sensing module and the recognition module. This invention's intelligent chessboard avoids the impact of complex lighting environments on chess piece recognition and can meet the needs of chess piece recognition in most situations. Furthermore, this invention's intelligent chessboard also has the advantages of low cost, fast recognition speed, high recognition success rate, and perfect support for human-computer interaction in intelligent chess games.

[0006] The above solution uses a dual-module hybrid identification framework that identifies the position and number of pieces by embedding a magnetic sensing element below the placement point and sets up an RFID reader diagonally to identify captured pieces. This method has the drawbacks of a complicated capture identification process, which requires manually placing the captured pieces in the RFID identification area, increasing the user's operational burden, and is prone to missed or incorrect identification.

[0007] For example, some smart board games employ visual recognition solutions. These solutions use cameras to capture images and combine them with visual recognition algorithms to process the captured images and determine the features and positions of the pieces. However, this approach suffers from several drawbacks: misaligned pieces leading to recognition failure, complex and inconvenient camera hardware, significant susceptibility to ambient lighting conditions, and low transmission and recognition efficiency. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings and deficiencies of the prior art and provide an intelligent chessboard with magnetic ring chess pieces. The intelligent chessboard has its own address code sequence, which transmits the chess piece ID information through the N and S poles in sequence.

[0009] The objective of this invention is achieved through the following technical solution:

[0011] Alternatively, the intelligent chessboard is a chess set, comprising 32 magnetic ring pieces and a chessboard capable of recognizing 64 positions;

[0012] The magnetic ring chess piece has two magnetic ring positions at the bottom; each magnetic ring position has 6 states:

[0013] (1) A magnetic ring with the N pole on the lower surface is placed in all regions of the magnetic ring position, which is defined as the N state;

[0014] (2) A magnetic ring with the lower surface as the S pole is placed in all regions of the magnetic ring position, which is defined as the S state;

[0015] (3) When there is no magnetic ring in any region of the magnetic ring position, it is defined as the Z state;

[0016] (4) The N and S pole magnetic rings on the lower surface are set in a region with a 180° interval between magnetic ring positions, which is defined as the NS state;

[0093] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0094] 1. Each position on the chessboard of the present invention can be located by the magnetic induction chip of the present invention;

[0095] Each magnetic ring on a magnetic ring chess piece can be defined with up to a decimal number, which greatly reduces the number of magnetic rings required for a chess piece, effectively reducing costs and improving reliability;

[0096] The magnetic induction chip can identify the ID of a magnetic ring chess piece by recognizing the state of all the magnetic rings on the piece. Furthermore, the magnetic ring chess piece is a passive device, making it simple and reliable.

[0097] 2. After the chessboard MCU of this invention is powered on, it can sort and locate the position of each magnetic induction chip, similar to having a built-in "coordinate positioning" function. From a physical point of view, when a chess piece is placed, one magnetic element corresponds to one magnetic induction chip.

[0098] 3. When the chessboard magnetic induction chip of this invention adopts a magnetic full-color chip and a magnetic all-in-one chip, the dual-channel hot standby (serial + parallel) transmission circuit ensures that the magnetic induction chip still has the ability to continue to operate when there is a partial failure.

[0099] It should be noted that serial data line networks and parallel data line networks refer to the connection relationship between n magnetic induction chips, and serial communication is always used when transmitting magnetic induction data. When transmitting magnetic induction data through a parallel data line network, it is defined as parallel serial single-bus communication; when transmitting magnetic induction data through a serial data line network, it is defined as serial serial single-bus communication.

[0100] 4. This invention transmits information through a stable magnetic pole signal arrangement, exhibiting strong anti-interference capabilities. The chess pieces have magnetic rings, and soft magnets at the placement points on the chessboard assist in positioning, effectively solving the problem of inaccurate placement and improving the feel and viewing comfort of the game. By transmitting piece identity information point-to-point and the chessboard continuously and autonomously scanning information at each position, it effectively handles operations such as capturing, undoing moves, and deductions during the game.

[0101] 5. This invention does not introduce elements external to the chess pieces and chessboard, thus avoiding the problem of inconvenience in carrying and storing due to the complex structure of visual solutions, and retaining the excellent feel of traditional smart chess and card games.

[0102] 6. This invention provides a method for expressing A method for identifying elements (n is a natural number) can be applied to various board games, such as Chinese chess (32 pieces, 90 positions), international chess (32 pieces, 64 positions), and military chess (50 pieces, 60 positions).

[0103] 7. The electrical network for communication between the chessboard MCU and the magnetic ring chess pieces of the entire chessboard in this invention consists of only 3 to 5 networks. For example, the electrical network using the magnetic color chip has 3 networks (VCC, GND, DIO), and the electrical network using the magnetic full-color chip has 5 networks (VCC, GND, DIO, DIN, DOUT). Therefore, the circuit board containing the magnetic induction chip can be made into a single-sided FPC or PCB, and the chessboard can be made into a scroll chessboard or a separate chessboard.

Each magnetic ring position can accommodate a magnetic ring with its lower surface having the N pole, defined as the N state; or a magnetic ring with its lower surface having the S pole, defined as the S state; or no magnetic ring, defined as the Z state. The N state, S state, and Z state freely correspond to the three ternary digits 2, 1, and 0; for example... Figure 7 and Figure 9 The three magnetic ring positions form 27 different states. Excluding the state where none of the three magnetic ring positions have a magnetic ring, the remaining 26 states correspond to ID1 to ID26 of the 26 magnetic ring pieces. Each state corresponds to a ternary digital state signal, which has 3 bits.

[0134] From the 27th to the 32nd magnetic ring pieces, each piece has three magnetic ring positions at its bottom, from the inside out: first magnetic ring position 1, second magnetic ring position 2, and third magnetic ring position. The third magnetic ring position has two opposing first semi-circular magnetic rings 4 and 5, with opposite polarities on their lower surfaces. The weight code for the outermost magnetic ring position is defined as 27. First magnetic ring positions 1 and 2 can accommodate magnetic rings with an N-pole lower surface (defined as N state), or magnetic rings with an S-pole lower surface (defined as S state), or no magnetic ring (defined as Z state). The N, S, and Z states freely correspond to the three ternary digits 2, 1, and 0. Figure 8 The third magnetic ring position is fixed. The first magnetic ring position 1 and the second magnetic ring position 2 form a ternary state signal of 2 bits, which forms a total of 9 different states. Six states are selected and combined with the control code 27 of the third magnetic ring position, corresponding to the ID27, ID28, ID29, ID30, ID31 and ID32 of the six magnetic ring pieces.

[0135] Four magnetic induction chips 9 are set at each position on the chessboard, and the four magnetic induction chips 9 share one chessboard position; the first magnetic ring position 1 corresponds to the first magnetic induction chip, the second magnetic ring position 2 corresponds to the second magnetic induction chip, and the third magnetic ring position 3 corresponds to the third and fourth magnetic induction chips that are 180 degrees apart; the third magnetic ring position has four status signals: "N polarity, S polarity, no magnetism, and simultaneously having N polarity and S polarity", and the first magnetic ring position 1 and the second magnetic ring position 2 each have three status signals: "N polarity, S polarity, and no magnetism". The magnetic induction chips sense the status signals to identify the ID information of 1 to 32 magnetic ring chess pieces.

[0136] For the magnetic ring pieces ID1 to ID26, the third magnetic induction chip and the fourth magnetic induction chip sense the same polarity SS and NN of the third magnetic ring position, which are equivalent to the S state and N state, respectively.

[0137] like Figure 1 , 2 The black magnetic ring chess piece "Rook" has an ID of 32, as shown below. Figure 3 Its starting position on the chessboard is numbered 90. The other magnetic ring pieces follow the same pattern.

[0138] After determining the correspondence between the magnetic ring state and the ternary code for each magnetic ring position, the ID codes for pieces ID1 to ID26 are referenced. Figure 7 To proceed. For example, such as Figure 1 , 2 The ID5 encoding method of the red chess piece "General" is as follows: Figure 7The status signals of the third, second, and first magnetic ring positions are Z, S, and N (i.e., the third, second, and first magnetic ring positions are set to no magnetic ring, S-polarity magnetic ring, and N-polarity magnetic ring, respectively), which correspond to the ternary digits 0, 1, and 2. They are multiplied by the ternary weight codes 9, 3, and 1, and then added together, i.e.: 0×9+1×3+2×1=5, i.e., ID5.

[0139] After determining the correspondence between the magnetic ring state and the ternary code for each magnetic ring position, the ID codes for pieces ID27 to ID32 are referenced. Figure 8 To proceed. For example, such as Figure 1 , 2 The ID28 encoding method of the black chess piece "General" is as follows: Figure 8 The status signals of the third, second, and first magnetic ring positions are (SN), Z, and S (i.e., the third, second, and first magnetic ring positions are respectively set with SN polarity magnetic ring, S polarity magnetic ring, and N polarity magnetic ring), which correspond to the ternary digits 1, 0, and 1. They are multiplied by the ternary weight codes 27, 3, and 1 respectively and then added together, that is: 1×27+0×3+1×1=28, which is ID28.

[0140] like Figure 3 , 4 Since the four magnetic induction chips share one chessboard position, the four magnetic induction chips corresponding to position 90 are the 360th (90×4), 359th, 358th, and 357th magnetic induction chips, respectively; the four magnetic induction chips corresponding to position 89 are the 356th (89×4), 355th, 354th, and 353rd magnetic induction chips, respectively; and the four magnetic induction chips corresponding to position 88 are the 352nd (88×4), 351st, 350th, and 349th magnetic induction chips, respectively.

[0141] The magnetic induction chips at each position on the chessboard are distributed in an equally spaced circular or radial pattern at the bottom of the chessboard.

[0142] A circular soft magnet is placed at the center of each chessboard. The circular soft magnet attracts the magnetic ring of the chess piece, thus returning the chess piece to its position.

[0143] The chessboard also includes a sound module that emits sound effects when magnetic ring chess pieces with different IDs are picked up or put down.

[0144] like Figure 10 The magnetic induction chip is a magnetic full-color chip, which contains GRB LED beads and integrates a magnetic induction circuit, a GRB color driving circuit, an address code memory, and a serial communication circuit with a single bus in series and parallel connection. It includes a power supply pin, a grounding pin, a parallel data line pin, an address code input pin, and an address code output pin. The power supply pin is used to supply power to the magnetic full-color chip, and the grounding pin is used for signal grounding and power grounding.

[0145] like Figure 5The address code input pins and address code output pins of n magnetic full-color chips are cascaded to form a series data line network DIN(1)-DOUT(n). The two ends of the series data line network DIN(1) and DOUT(n) are connected to the MCU respectively. The MCU writes the sequence bit formed by the cascaded magnetic full-color chips into the address code memory through the series data line network DIN(1)-DOUT(n) and uses it as the communication address code. The power supply pins of n magnetic full-color 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 parallel data line pins are connected in parallel to form a parallel data line network DIO, which is then connected to the MCU.

[0146] Serial-parallel single-bus serial communication circuits are used to process serial data line network information and parallel data line network information.

[0147] GRB holographic information and magnetic induction data information can be transmitted on the parallel data line network DIO;

[0148] GRB holographic information and magnetic induction data can also be transmitted on the serial data line network DIN(1)-DOUT(n);

[0149] Both the parallel data line network and the serial data line network use the serial single-bus communication protocol to transmit GRB holographic information and magnetic induction data, and they serve as hot backups for each other.

[0150] Example 2

[0151] Example 2 is identical to Example 1 except for the following content:

[0152] A smart chessboard with magnetic ring pieces, the smart chessboard being a Chinese chess board, comprising 32 magnetic ring pieces and a chessboard capable of recognizing 90 positions;

[0153] Among them, such as Figures 11 to 13 The bottom of the magnetic ring chess piece has four magnetic ring positions, from the inside out: first magnetic ring position 1, second magnetic ring position 2, third magnetic ring position 3, and fourth magnetic ring position 6. Each magnetic ring position can hold a magnetic ring with its lower surface as the N pole, defined as the N state; or a magnetic ring with its lower surface as the S pole, defined as the S state; or no magnetic ring, defined as the Z state. The N state, S state, and Z state freely correspond to the three ternary numbers 2, 1, and 0; for example... Figure 14 The four magnetic ring positions form 81 different states. After excluding the states where there are no magnetic rings in all four positions, 32 states are selected from the 80 states, corresponding to the IDs of the 32 magnetic ring pieces. Each state corresponds to a ternary digital state signal, which has 4 bits.

[0154] Four magnetic induction chips are set at each position on the chessboard. The four magnetic induction chips share one chessboard position, and one magnetic induction chip corresponds to one magnetic ring position. Each magnetic ring has three state signals: N polarity, S polarity, and no magnetism. The magnetic induction chips sense the state signals to identify the ID information of 1 to 32 magnetic ring chess pieces.

[0155] After determining the correspondence between the magnetic ring state and the ternary code for each magnetic ring position, the ID codes for the pieces ID1 to ID32 are referenced. Figure 14 Proceed. For example... Figure 1 , 2 The ID25 piece corresponds to the black knight, and its encoding method is as follows: Figure 14 The status signals of the third, second, and first magnetic ring positions are Z, N, N, and S (i.e., the third, second, and first magnetic ring positions are respectively set with SN polarity magnetic rings, S polarity magnetic rings, and N polarity magnetic rings), which correspond to the ternary digits 0, 2, 2, and 1. They are multiplied by the ternary weight codes 27, 9, 3, and 1 respectively and then added together, that is: 0×27+2×9+2×3+1×1=25, which is ID25.

[0156] like Figure 11 Since the four magnetic induction chips share one chessboard position, the four magnetic induction chips corresponding to position 90 are the 360th (90×4), 359th, 358th, and 357th magnetic induction chips, respectively; the four magnetic induction chips corresponding to position 89 are the 356th (89×4), 355th, 354th, and 353rd magnetic induction chips, respectively; and the four magnetic induction chips corresponding to position 88 are the 352nd (88×4), 351st, 350th, and 349th magnetic induction chips, respectively.

[0157] Example 3

[0158] Example 3 is identical to Example 1 except for the following content:

[0159] A smart chessboard with magnetic ring pieces, the smart chessboard being a Chinese chess board, comprising 32 magnetic ring pieces and a chessboard capable of recognizing 90 positions;

[0160] The bottom of the magnetic ring chess piece has 5 magnetic ring positions. Each magnetic ring position has two states, which can be selected from the following three states: the magnetic ring position is equipped with a magnetic ring with the N pole on the lower surface, which is defined as the N state; the magnetic ring position is equipped with a magnetic ring with the S pole on the lower surface, which is defined as the S state; the magnetic ring position is not equipped with a magnetic ring, which is defined as the Z state.

[0161] Each magnetic ring position has two states that freely correspond to two binary digits, 1 and 0; the 5 magnetic ring positions form 32 different permutations. Excluding the state where none of the 5 magnetic ring positions have a magnetic ring, there are 31 IDs for the magnetic ring pieces; each state corresponds to a binary digit state signal, and the ternary digit state signal has 5 bits; the remaining magnetic ring piece can be set to the NS state or NSNS state in one of the magnetic ring positions, as long as it is different from the original N state, S state, and Z state. The states of the other two magnetic rings can be freely set to any one of the N state, S state, Z state, NS state, NSNS state, or other newly set states.

[0162] The magnetic ring position is equipped with one magnetic ring with the N pole on its lower surface and one magnetic ring with the S pole on its lower surface, which is defined as the NS state; the magnetic ring position is equipped with two magnetic rings with the N pole on their lower surface and two magnetic rings with the S pole on their lower surface, with magnetic rings of opposite polarities spaced apart, which is defined as the NSNS state.

[0163] Five magnetic induction chips are set at each position on the chessboard, with one magnetic induction chip corresponding to one magnetic ring position, and the five magnetic induction chips share one chessboard position; each magnetic ring has two status signals, and the magnetic induction chips sense the status signals to identify the ID information of 1 to 32 magnetic ring chess pieces.

[0164] Example 4

[0165] A smart chessboard with magnetic ring pieces, the smart chessboard being a Chinese chess board, comprising 32 magnetic ring pieces and a chessboard capable of recognizing 90 positions;

[0166] The magnetic ring chess piece has two magnetic ring positions at the bottom; each magnetic ring position has 6 states:

[0167] (1) A magnetic ring with the N pole on the lower surface is placed in all regions of the magnetic ring position, which is defined as the N state;

[0168] (2) A magnetic ring with the lower surface as the S pole is placed in all regions of the magnetic ring position, which is defined as the S state;

[0169] (3) When there is no magnetic ring in any region of the magnetic ring position, it is defined as the Z state;

[0170] (4) The N and S pole magnetic rings on the lower surface are set in a region with a 180° interval between magnetic ring positions, which is defined as the NS state;

[0171] (5) The area with a 180° interval between magnetic rings is defined as the N-pole magnetic ring and the area without a magnetic ring on the lower surface, which is called the NZ state;

[0172] (6) The area with a 180° interval between magnetic ring positions is defined as the S-pole magnetic ring and the area without magnetic ring on the lower surface, which is called the SZ state;

[0173] The N, S, Z, NS, NZ, and SZ states each correspond to the six hexadecimal digits 5, 4, 3, 2, 1, and 0. The two magnetic ring positions form 36 different states. Excluding states where neither position has a magnetic ring, 32 states are selected from these 35, corresponding to the IDs of the 32 magnetic ring pieces. Each state corresponds to a hexadecimal digit state signal, which has two bits.

[0174] Six magnetic induction chips are set at each position on the chessboard, and the six magnetic induction chips share one chessboard position; three magnetic induction chips correspond to one magnetic ring position; and the three magnetic induction chips are placed at 120° intervals on the chessboard corresponding to each magnetic ring position; the magnetic induction chips sense the state signal to identify the ID information of 1 to 32 magnetic ring chess pieces.

[0175] Because the six magnetic induction chips share one chessboard position, the six magnetic induction chips corresponding to position 90 are the 540th (90×6), 539th, 538th, 537th, 536th, and 535th magnetic induction chips; the six magnetic induction chips corresponding to position 89 are the 534th (89×6), 533rd, 532nd, 531st, 530th, and 529th magnetic induction chips; and the six magnetic induction chips corresponding to position 88 are the 528th (88×6), 527th, 526th, 525th, 524th, and 523rd magnetic induction chips.

[0176] When the magnetic ring position is in the NS, NZ, or SZ state, if two magnetic induction chips are set at the corresponding positions on the chessboard, the critical state (i.e., the two magnetic induction chips are exactly located at the boundary between the N-pole magnetic ring region and the S-pole magnetic ring region, the boundary between the N-pole magnetic ring region and the non-magnetic ring region, and the boundary between the S-pole magnetic ring region and the non-magnetic ring region) cannot be eliminated, which may lead to inaccurate identification of the magnetic ring chess pieces.

[0177] To eliminate this extreme situation, the present invention employs an electronic technology method that adds a magnetic induction chip, for example, as... Figure 23 , 24 At each magnetic ring position on the chessboard, three magnetic sensing chips spaced 120° apart are used. If one chip is in a critical state, the other two chips will be in a non-critical state, allowing for normal detection of NS, NZ, or SZ states. For example, if the magnetic ring position is in an SN state, and one chip is in a critical state, the reading will be either S or N. The other two chips will read one S and one N, resulting in either SSN or SNN. Both of these results are essentially SN states, thus eliminating the adverse effects of the critical state. An additional magnetic sensing chip is added to eliminate the critical state and accurately identify the magnetic ring piece ID.

[0178] At this point, the corresponding hexadecimal digit definition table is as follows:

[0179] Table 1

[0180]

[0181] The ID encoding rules corresponding to Table 1 are as follows: Figure 22 .

[0182] Alternatively, this invention can also employ a physical positioning method without adding a magnetic induction chip: taking the center of each magnetic ring position corresponding to the chessboard as the center, two positioning magnetic elements are placed at 180° intervals or four positioning magnetic elements at 90° intervals at each position on the chessboard. The area of ​​the positioning soft magnet is much smaller than the area of ​​the 180° magnetic ring. Because the magnetic force is strongest in the middle of the magnetic ring, the positioning soft magnet always tends to be centered on the magnetic ring position corresponding to the chessboard position. The positioning soft magnet is set with a corresponding positioning soft magnet for the magnetic ring chess piece, and the positioning soft magnet and the positioning magnetic element attract each other to complete the positioning of the magnetic element. In this way, the magnetic ring chess piece can be placed at each position on the chessboard, which is applicable to the three states SZ, NZ, and SN, without affecting the overall states S, N, and Z.

[0183] like Figure 20 , 21 At position 90 on the chessboard, four positioning magnetic elements 8 are placed at 90° intervals around the center of that position. Correspondingly, four positioning soft magnets 7 are placed on each magnetic ring chess piece. Other positions are similar to other magnetic ring chess pieces.

[0184] like Figure 2 , 20 At position 90 on the chessboard, the initial position is a black "Rook," with an ID of 32. The state signals of its magnetic ring from the outside in are NS and NZ, corresponding to the hexadecimal digits 5 and 2 respectively. These are multiplied by the hexadecimal weight codes 6 and 1 respectively, and then added together: 5 × 6 + 2 × 1 = 32, which is ID 32. Figure 22 The ID encoding rules are consistent.

[0185] Figure 22 The corresponding hexadecimal digit definition table is shown in Table 2:

[0186] Table 2

[0187]

[0188] Example 5

[0189] A smart chessboard with magnetic ring pieces, the smart chessboard being a Chinese chess board, comprising 32 magnetic ring pieces and a chessboard capable of recognizing 90 positions;

[0190] Alternatively, the intelligent chessboard is a chess set, comprising 32 magnetic ring pieces and a chessboard capable of recognizing 64 positions;

[0191] The magnetic ring chess piece has two magnetic ring positions at its bottom; each magnetic ring position has three magnetic induction chips spaced 120° apart, corresponding to the position on the chessboard.

[0192] Each magnetic ring position is configured with 10 states:

[0193] (1) A magnetic ring with the N pole on the lower surface is placed in all regions of the magnetic ring position, which is defined as the NNN state;

[0194] (2) When all regions of the magnetic ring position are filled with magnetic rings whose lower surface is the S pole, it is defined as the SSS state;

[0195] (3) When there is no magnetic ring in any region of the magnetic ring position, it is defined as the ZZZ state;

[0196] (4) One-third of the magnetic ring position is an S-pole magnetic ring, and two-thirds of the magnetic ring position is without a magnetic ring, which is defined as the SZZ state (equivalent to ZZS and ZSZ).

[0197] (5) One-third of the magnetic ring positions are N-pole magnetic rings, and two-thirds of the magnetic ring positions are without magnetic rings, which is defined as the NZZ state (equivalent to ZZN and ZNZ).

[0198] (6) One-third of the magnetic ring positions are S-pole magnetic rings, one-third of the magnetic ring positions are N-pole magnetic rings, and one-third of the magnetic ring positions are without magnetic rings, which is defined as SNZ state (equivalent to SZN, NSZ, NZS, ZSN, ZNS).

[0199] (7) Two-thirds of the magnetic ring positions are S-pole magnetic rings, and one-third of the magnetic ring positions are without magnetic rings, which is defined as SSZ state (equivalent to ZSS, SZS).

[0200] (8) Two-thirds of the magnetic ring positions are N-pole magnetic rings, and one-third of the magnetic ring positions are without magnetic rings, which is defined as NNZ state (equivalent to ZNN, NZN).

[0201] (9) Two-thirds of the magnetic ring position is an S-pole magnetic ring and one-third of the magnetic ring position is an N-pole magnetic ring, which is defined as the SSN state (equivalent to NSS, SNS).

[0202] (10) Two-thirds of the magnetic ring positions are N-pole magnetic rings and one-third of the magnetic ring positions are S-pole magnetic rings, which is defined as NNS state (equivalent to SNN, NSN).

[0203] The 10 states correspond to the ten decimal digits 9, 8, 7, 6, 5, 4, 3, 2, 1, and 0. The two magnetic ring positions form 100 different states. After excluding the states where neither magnetic ring position has a magnetic ring, 32 states are selected from the 99 different states, corresponding to the IDs of the 32 magnetic ring pieces. Each state corresponds to a decimal digit state signal, which has 2 bits.

[0204] Six magnetic induction chips are set at each position on the chessboard, and the six magnetic induction chips share one chessboard position; three magnetic induction chips correspond to one magnetic ring position; the magnetic induction chips sense the state signal to identify the ID information of 1 to 32 magnetic ring chess pieces.

[0205] Essentially, this invention uses a multi-base encoding method to assign a unique ID to each magnetic ring chess piece based on the polarity combination of its magnetic ring positions. A magnetic induction chip is then placed at each position on the chessboard to identify these unique IDs, thus completing the identification of the magnetic ring chess piece. In practice, the larger the value of M in the M-base encoding, the fewer magnetic ring positions and magnetic rings are required. Some pieces can be encoded using M-base, while others can be encoded using m-base, where M is not equal to m. For chess or international chess, as long as 32 different IDs can be achieved, and corresponding magnetic induction chips are set up, it is sufficient. For other types of chess, only the number of IDs differs; the encoding method remains essentially unchanged.

[0206] Meanwhile, the magnetic induction chip at each position on the chessboard uses natural sequence encoding or written address code to identify the position of the magnetic ring chess piece on the chessboard.

[0207] Therefore, the present invention is designed as follows:

[0208] The bottom of the magnetic ring chess piece has L magnetic ring positions, where L is greater than or equal to 2; each magnetic ring position corresponds to M states, where M is greater than or equal to 2.

[0209] M states correspond to M digits in an M-ary system; L magnetic ring bits form L bits of an M-ary state signal, resulting in a total of... A different arrangement Greater than or equal to 33, from Select 32 permutations from the given permutations, corresponding to the IDs of 32 magnetic ring chess pieces;

[0210] L magnetic induction chips are set at each position on the chessboard, with one magnetic induction chip corresponding to one magnetic ring position, and L magnetic induction chips share one chessboard position; each magnetic ring has M status signals, and the magnetic induction chips sense the status signals to identify the ID information of 1 to 32 magnetic ring chess pieces.

[0211] Generally, it is reasonable to set 2 to 5 magnetic ring positions on a magnetic ring chess piece. Therefore, the present invention also includes the following design:

[0212] A smart chessboard with magnetic ring pieces, the smart chessboard being a Chinese chess board, comprising 32 magnetic ring pieces and a chessboard capable of recognizing 90 positions;

[0213] Alternatively, the intelligent chessboard is a chess set, comprising 32 magnetic ring pieces and a chessboard capable of recognizing 64 positions;

[0214] The bottom of the magnetic ring chess piece has 2 to 5 magnetic ring positions;

[0215] Each magnetic ring position can be set to a maximum of 5 states:

[0216] A magnetic ring with its lower surface having the N pole is placed in all regions of the magnetic ring position, which is defined as the N state;

[0217] A magnetic ring with its lower surface as the S pole is placed in all regions of the magnetic ring position, which is defined as the S state;

[0218] The area where there is no magnetic ring in any region of the magnetic ring position is defined as the Z state;

[0219] The N and S pole magnetic rings on the lower surface are set in a 180° interval area of ​​the magnetic ring position, which is defined as the NS state. In the NS state, the magnetic induction chip is placed at 180° intervals on the chessboard corresponding to the magnetic ring position.

[0220] The magnetic ring position is set with N-pole, S-pole, N-pole, S-pole magnetic rings on the lower surface at 90° intervals, which is defined as NSNS state. In NSNS state, the magnetic induction chip is placed at 90° intervals on the chessboard corresponding to the magnetic ring position.

[0221] Each magnetic ring position has at least two states, and the two states are any two of the five states;

[0222] Based on the state number of the magnetic ring position, a corresponding multi-base system is selected, and the multi-base digits are associated with the states of the magnetic ring positions. By performing multi-base encoding on the polarity combination of the magnetic ring positions of the magnetic ring chess piece, a unique ID is assigned to the magnetic ring chess piece. A magnetic induction chip is set at each position on the chessboard to identify the unique ID, thus completing the identification of the magnetic ring chess piece. At the same time, the magnetic induction chip at each position on the chessboard is used for natural sequence encoding or address code writing to complete the identification of the position of the magnetic ring chess piece on the chessboard.

[0223] The intelligent chessboard described in the above embodiments can be made into a foldable chessboard or a detachable chessboard. In embodiments 1 to 3, the magnetic induction chip can also be one of the following: a magnetic color-changing chip, a magnetic color-gathering chip, a magnetic magic chip, a magnetic concentrator chip, or a magnetic oscillator chip. Magnetic induction chips require fewer pins (4, 3, 5, 4, 3, and 5 respectively), naturally supporting foldable and detachable chessboards.

[0224] like Figure 15The magnetic color chip contains GRB LED beads and integrates a magnetic induction circuit, a GRB color driving circuit, and a series single-bus serial communication circuit, including a power supply pin, a grounding pin, a series signal input pin, and a series signal output pin; the power supply pin is used to power the magnetic color chip, and the grounding pin is used for signal grounding and power grounding;

[0225] The serial signal input pins and serial signal output pins of n magnetic color chips are cascaded to form a serial data line network DIN(1)-DOUT(n). The two ends of the serial data line network DIN(1) and DOUT(n) are connected to the MCU respectively.

It includes a power supply pin, a grounding pin, and a parallel data line pin. The power supply pin is used to supply power to the magnetic color chip, and the grounding pin is used for signal grounding and power grounding.

[0230] The parallel data pins of n magnetic color chips are connected together to form a parallel data line network DIO, which is then connected to the MCU; the address code of the magnetic color chip is written into the address code memory through an external fixture and used as the communication address code;

[0235] The serial signal input pins and serial signal output pins of n magnetic magic chip chips are cascaded to form a serial data line network DIN(1)-DOUT(n). The two ends of the serial data line network DIN(1) and DOUT(n) are connected to the MCU respectively. The MCU transmits magnetic induction data information to the MCU through the serial data line network DIN(1)-DOUT(n).
