Description

Technical Field

[0001] This invention relates to the field of judging chess competitions, and more particularly to an electronic refereeing device and refereeing method for land battle chess. Background Technology

[0002] Military Chess (Dark Chess) is a highly strategic board game. Its gameplay revolves around "troop movement and formation," and its core appeal lies in the strategic maneuvering and judgment under conditions of information asymmetry. Traditional Military Chess requires at least three players: one referee and two players. This limitation significantly reduces the game's convenience, making it difficult to start playing anytime and increasing its limitations.

[0003] Existing intelligent electronic chess sets typically employ chessboard push-button sensing technology, requiring complex circuitry at each point on the board, resulting in high costs. Furthermore, prolonged pressing can damage the board, making repairs difficult. Additionally, existing technologies also rely on barcode scanning for identification, which, while capable of recognizing pieces, requires additional scanning equipment, is cumbersome, and is susceptible to variations in lighting and piece placement angles, leading to poor stability. Summary of the Invention

[0004] The purpose of this invention is to provide an electronic refereeing device and refereeing method for land battle chess, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An electronic refereeing device for land battle chess, including a refereeing mechanism installed on the refereeing device.

[0006] In a preferred embodiment, the refereeing body includes a placement platform with a slot for placing chess pieces. The slot is equipped with an electrode contactor and a positioning contactor, the positioning contactor being used to detect whether the chess pieces are placed in the correct position.

[0007] In a preferred embodiment, the referee device is equipped with a central processing unit, and the electrode contactor is used to read the level signal of the chess piece and transmit it to the central processing unit.

[0008] In a preferred embodiment, the placement platform is also provided with a plastic plate.

[0009] In a preferred embodiment, the interior of the plastic plate is equipped with an LED light source and a buzzer, which are electrically connected to the central processing unit to display the judgment result.

[0010] In a preferred embodiment, the central processing unit is a microcontroller chip, which stores the land battle chess rule judgment code, dynamic battle judgment algorithm and anti-cheating mechanism code; In one preferred embodiment, the dynamic battle determination algorithm is used to determine the winner by combining the piece level and special rules, and the anti-cheating mechanism code is used to trigger an alarm prompt based on the detection result of the positioning contactor.

[0011] In one preferred embodiment, the surface of the chess piece in the land battle game adapted to the referee device is provided with multiple metal contact points. The metal contact points form a bit binary code through different connection combinations of short circuit, open circuit or resistance value difference. The electrode contactor identifies the chess piece by reading the high and low level signals corresponding to the binary code.

[0012] A method for electronic refereeing in land battle chess includes the following steps: Step 1: Place the two chess pieces to be judged into the placement slots of the referee device, and use the positioning contactor to detect whether the pieces are in the correct position; Step 2: If the location is incorrect, trigger an alarm. Step 3: If the position is correct, the electrode contactor reads the high and low level signals corresponding to the 4-bit binary code formed by the metal contact points on the surfaces of the two chess pieces, and transmits the signals to the central processing unit. Step 4: The central processing unit uses a dynamic combat judgment algorithm combined with the land battle chess rule judgment code to determine the winner based on the identity and level of the two pieces; Step 5: The result is determined by an LED light source and a buzzer inside the plastic panel, which are displayed in an audio-visual manner. The LED light source uses different colors, with red light indicating defeat and green light indicating victory, to show the result. The buzzer provides different sound effects to assist in the prompting.

[0013] Furthermore, the surface of the chess pieces on the adapter referee device is provided with multiple metal contact points. The metal contact points form a 4-bit binary code through different connection combinations of short circuit, open circuit or resistance value difference. The electrode contactor 4 identifies the chess piece by reading the high and low level signals corresponding to the binary code.

[0014] Furthermore, current is input from the positioning contact at the upper right corner of the chess piece. If the chess piece is in the correct position (the contact is aligned), the current is transmitted through the internal wire to the positioning contact at the lower left corner to form a closed loop. The central processing unit receives the "position correct" signal. If the position is incorrect (the contact is misaligned or not placed steadily), the loop is broken, the buzzer emits a continuous alarm sound, and at the same time, the LED at the corresponding position on the plastic semi-transparent light panel flashes red light.

[0015] As a preferred implementation, based on step 3, the binary code is generated in the following manner: Among the metal contact points on the surface of the chess piece, those with metal markers form a low level (binary "0"), while those without metal markers form a high level (binary "1"). The 4-bit binary code corresponds to 12 types of chess piece identities in the land battle game: Flag 0001, Engineer 0010, Platoon Leader 0011, Company Commander 0100, Battalion Commander 0101, Regiment Commander 0110, Brigade Commander 0111, Division Commander 1000, Army Commander 1001, Commander 1010, Landmine 1011, and Bomb 1100.

[0016] In a preferred embodiment, in step 1, the positioning contactor determines the position of the chess piece by detecting the current path; The current is input from the first metal contact point in the upper right corner of the chess piece. If it can be transmitted through the internal circuitry of the chess piece to the second metal contact point in the lower left corner and output, then the position is determined to be correct. Conversely, if the location is incorrect, an alarm will be triggered.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses 4-bit binary encoding to uniquely and accurately identify 12 types of chess pieces. Combined with the dynamic battle determination algorithm built into the central processing unit, it can complete complex level comparisons and rule matching within milliseconds. Whether it is a regular chess piece level battle or a special rule such as "engineer digging up landmines" or "bomb destroying any piece together", it can be executed accurately, ensuring objective and consistent battle results and avoiding delays and errors caused by human judgment.

[0018] The positioning contactor of this invention strictly determines the position of the chess piece by detecting the current path. The determination process will only be initiated when the "input point" and "output point" of the chess piece form a closed loop. Once the position is abnormal, an audible and visual alarm will be triggered immediately. This physically prevents players from moving chess pieces or blocking the contact points, thus preventing cheating behaviors. At the same time, it prevents signal reading errors caused by placement deviations, ensuring fair and just gameplay.

[0019] The central processing unit of this invention can easily update the rule code in the later stages to adapt to various gameplay modes such as "Dark Chess Mode" and "Custom Rule Battle", meeting the personalized needs of different players; the 4-bit binary code supports 16 combinations, covering 12 regular chess pieces, and also reserves sufficient expansion space to add special chess piece types as needed. It is suitable for family entertainment and friends' gatherings, and can also play an important role in professional scenarios such as land battle chess competitions, with broad application prospects.

[0026] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0027] See Figure 1-4 This embodiment provides an electronic referee device for land battle chess, including a refereeing mechanism disposed on the referee device 1.

[0028] The refereeing apparatus includes a placement platform 2, which has a placement slot 3 for placing chess pieces. The placement slot 3 is equipped with an electrode contactor 4 and a positioning contactor 6. The positioning contactor 6 is used to detect whether the chess pieces are placed in the correct position.

[0029] Specifically, the referee device 1 is a rectangular, cubic, or irregularly shaped shell, and the outer shell is made of ABS or PETG plastic.

[0030] The placement platform 2 is integrally formed with the top cover to increase the load-bearing capacity. It has two symmetrical placement slots 3 for placing the chess pieces. The slots are reserved for the installation positions of electrode contactors and positioning contactors.

[0031] Specifically, electrode contactor 4: each placement slot is equipped with 6 metal probes (corresponding to 4-bit binary code), the tip of the probe protrudes 0.04-0.12cm, preferably 0.08cm, from the surface of the placement slot, for contacting the metal contacts on the surface of the chess piece, reading high and low level signals (high level > 3V, low level < 0.3V), and connected to the central processing unit through wires.

[0032] Specifically, the positioning contactor 6 has two metal contacts in each slot (corresponding to the "current input point" and "current output point" of the chess piece), which are connected in series with a 3.3V DC power supply. When the chess piece is in the correct position, a closed circuit is formed, triggering a positioning confirmation signal.

[0033] The referee device 1 is equipped with a central processing unit, and the electrode contactor 4 is used to read the level signal of the chess piece and transmit it to the central processing unit.

[0034] Specifically, the central processing unit uses an ESP32 or STM32 microcontroller chip (supporting future firmware upgrades), installed inside the referee device, and is connected to the electrode contactor, positioning contactor, LED light source and buzzer through circuits. It stores the preset land battle chess rule code (such as "commander eats army commander" "engineer digs landmines", etc.), dynamic judgment algorithm and anti-cheating program.

[0035] A plastic board 5 is also provided on the placement platform 2.

[0036] Preferably, the plastic sheet 5 is made of ABS or PETG material.

[0037] Specifically, a plastic plate 5 covers the top of the placement platform (thickness 0.15-0.35cm, preferably 0.25cm), and is made of semi-transparent frosted material. Two sets of LED light sources are installed in it (corresponding to two placement slots), each set containing four red, blue and green LEDs. And a buzzer (frequency 2kHz) is used to output prompt sound effects (such as "beep-beep" to indicate that the judgment is completed, and "beep beep beep" to indicate that the position is wrong).

[0038] The plastic plate 5 is equipped with an LED light source and a buzzer, which are electrically connected to the central processing unit to display the judgment result.

[0039] The central processing unit is a microcontroller chip, which stores the code for judging the rules of land battle chess, the dynamic battle judgment algorithm, and the code for the anti-cheating mechanism. The dynamic battle determination algorithm is used to determine the winner by combining the level of the pieces and special rules, and the anti-cheating mechanism code is used to trigger an alarm prompt based on the detection result of the positioning contactor 6.

[0040] The surface of the chess pieces in the land battle game adapted to the referee device has multiple metal contact points. The metal contact points form a 4-bit binary code through different connection combinations of short circuit, open circuit or resistance value difference. The electrode contactor 4 identifies the chess piece by reading the high and low level signals corresponding to the binary code.

[0041] Specifically, the surface of the chess piece has two rows of metal contact points (copper material, diameter 0.10mm-0.35mm, preferably 0.25mm): each row has 6 metal contact points, 2 of which are positioning contacts (the upper left "input point" and the lower right "output point"), and are directly connected internally by wires; There are 4 coded contacts (arranged in a 2×2 straight rectangle). Different short-circuit / open-circuit combinations are designed according to the level of the chess piece (for example, in the coded contacts of "General", the 1st and 4th points are metal marks (low level "0"), and the 2nd and 3rd points are not metal marks (high level "1"), forming binary "1001".

[0042] See Figure 1-4 This embodiment provides an electronic refereeing method for land battle chess, which includes the following steps: Step 1: Place the two chess pieces to be judged into the placement slot 3 of the referee device 1, and use the positioning contactor 6 to detect whether the pieces are in the correct position; Step 2: If the location is incorrect, trigger an alarm. Step 3: If the position is correct, the electrode contactor 4 reads the high and low level signals corresponding to the 4-bit binary code formed by the metal contact points on the surfaces of the two chess pieces, and transmits the signals to the central processing unit. Step 4: The central processing unit uses a dynamic combat judgment algorithm combined with the land battle chess rule judgment code to determine the winner based on the identity and level of the two pieces; Step 5: The result is determined by the LED light source and buzzer inside the plastic plate 5, which are output in an audio-visual manner. The audio-visual manner includes the LED light source displaying the result by using different colors, with red light indicating defeat and green light indicating victory, and the buzzer providing auxiliary prompts through different sound effects.

[0043] This embodiment achieves automatic adjudication through a four-step process: "position detection - signal reading - intelligent judgment - result feedback". The specific steps are as follows: Position detection (anti-cheating mechanism): The user places two pieces to be judged into two placement slots 3 respectively, ensuring that the bottom of the pieces is in contact with the contact points in the slots.

[0044] Specifically, the positioning contactor 6 starts the detection: current is input from the positioning contact at the upper right corner of the chess piece. If the chess piece is in the correct position (the contacts are aligned), the current is transmitted through the internal wires to the positioning contact at the lower left corner to form a closed loop. The central processing unit receives the "correct position" signal. If the position is incorrect (the contacts are misaligned or not placed steadily), the loop is broken, the buzzer emits a continuous alarm sound, and at the same time, the LED at the corresponding position on the plastic semi-transparent light panel flashes red light.

[0045] Specifically, signal reading and encoding recognition; After the position is confirmed, the electrode contactor outputs 3.3V voltage to its four coded contacts, and the voltage level is detected by the pull-up resistor. - Contacts with metallic markings are pulled low due to short circuits, outputting "0"; - Contacts without metallic markings remain high, outputting "1".

[0046] For example, when "Commander" and "Army Commander" are placed, the electrode contactor reads the codes "1010" (Commander) and "1001" (Army Commander), and transmits the binary signals to the central processing unit and identifies them as the set piece codes (Commander, Army Commander).

[0047] Specifically, the dynamic judgment algorithm is executed; the central processing unit calls the built-in rule code to compare the levels of the two pieces: if it is a regular battle (such as "corps commander vs. division commander"), it is directly judged according to "the one with the higher level wins" (if the corps commander wins, the green light of the corresponding placement slot will light up, and the losing side will have a red light on). If special rules are involved (such as "bomb vs. commander"), the logic of "bomb and any piece perish together" will be triggered, and both sets of LEDs will light up red simultaneously.

[0048] Specifically, the results feedback (audio-visual output); After the judgment is completed, the central processing unit controls the LED above the slot corresponding to the winner to light up green and the LED above the loser to light up red (e.g., when "the commander wins against the army commander", the green light is on the slot where the commander is located and the red light is on the slot where the army commander is located). The buzzer emits a "beep" sound, marking the completion of one refereeing round.

[0049] Based on step 3, the binary code is generated in the following way: Among the metal contact points on the surface of the chess piece, those with metal markers form a low level (binary "0"), while those without metal markers form a high level (binary "1"). The 4-bit binary code corresponds to 12 types of chess piece identities in Land Battle Chess: Flag 0001, Engineer 0010, Platoon Leader 0011, Company Commander 0100, Battalion Commander 0101, Regiment Commander 0110, Brigade Commander 0111, Division Commander 1000, Army Commander 1001, Commander 1010, Landmine 1011, and Bomb 1100.

[0050] In step 1, the positioning contactor 6 determines the position of the chess piece by detecting the current path; Specifically, the current is input from the first metal contact point in the upper right corner of the chess piece. If it can be transmitted through the internal circuitry of the chess piece to the second metal contact point in the lower left corner and output, then the position is determined to be correct. Conversely, if the location is incorrect, an alarm will be triggered.

[0051] Specifically, typical application scenarios are: Taking the determination of "engineer vs. mine" as an example, the process is as follows: The user places the "Sapper" (code "0010") into the left slot and the "Mine" (code "1011") into the right slot.

[0052] Positioning detection: The two pieces are in the correct positions, the loop is closed, and the central processing unit confirms that the position is "determinable".

[0053] Signal reading: The electrode contactor reads the code "0010" (engineer) on the left and the code "1011" (mine) on the right.

[0054] Intelligent judgment: The central processing unit calls the rule "Sapper can dig up landmines" and judges "Sapper wins".

[0055] Results feedback: The left LED lights up green, the right LED lights up red, and the buzzer emits a "beep-beep" sound, allowing the user to intuitively obtain the judgment result.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole.
