Description

Technical Field

[0001] This application relates to a card game set with a sensor mark and its identification device, belonging to the field of card sorting machine technology. Background Technology

[0002] Tiles with raised lettering on the front include mahjong tiles, dominoes, and lamina tiles. These are double-sided tiles; the front features raised lettering for identification, while the back is flat. Identifying the front and back is necessary when shuffling these tiles. Taking mahjong tiles as an example, magnetic mahjong tiles have a large magnet embedded inside. A large flipping magnet is placed below the tile tray in the mahjong machine. The repulsion between the like poles of the internal magnet and the flipping magnet causes the tiles to flip in a uniform orientation. However, embedding the flipping magnet requires a large hole in the tile, resulting in a larger crack and making the tile prone to breakage. Furthermore, the tiles don't look aesthetically pleasing. To address this issue, non-magnetic playing cards could be used. However, even with non-magnetic cards, face-up identification is still necessary during shuffling. Currently, face-up identification on non-magnetic cards utilizes color sensors, identifying the front and back of the card based on color differences. This technology requires pre-calibration of the front and back of the card, followed by identification based on the calibration results. However, the colors of playing cards are diverse and uneven. Due to the patterns on the cards, the color positions of each card are also inconsistent, leading to low accuracy when using color sensors for face-up identification. Furthermore, situations where the front and back colors are similar result in even worse accuracy. Therefore, the technology using color sensors to identify the front and back of playing cards cannot meet current needs; a method is lacking that combines durable cards with a stable face-up identification mechanism.

[0037] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0038] Example 1, Reference Figures 1-4 This embodiment describes a mahjong tile as an example. By setting a sensor mark on the edge of the mahjong tile, the front and back of the mahjong tile can be identified using the sensor mark. This also solves the problem that magnetic mahjong tiles are prone to breakage. Specifically, it is a board game with a sensor mark, which includes an identification groove 5 on the edge of the board game 1, and a sensor mark 3 placed in the identification groove 5.

[0039] The sensing marker 3 is a magnet.

[0040] The identification groove 5 is vertically opened in the middle of the chessboard 1, or horizontally opened in the middle of the chessboard 1; or opened on the diagonal of the chessboard 1.

[0041] The sensor marker 3 is placed in the identification groove 5 in the middle of the chess and card game board.

[0042] A sensor marker 3 is placed in the horizontally positioned identification groove 5 in the middle of the horizontal part of the chessboard.

[0043] The sensor marker 3 is placed in the identification groove 5 at the diagonal position of the chess and card game board.

[0044] Example 2 differs from Example 1 in that the sensing marker is a metal body.

[0045] Example 3 differs from Example 1 or Example 2 in that the sensing marker 3 is a marker particle, marker sheet, marker strip, or marker block.

[0046] Example 4 differs from Example 1, Example 2, or Example 3 in that the identification groove 5 is located on the front of the chessboard.

[0047] The identification groove 5 can be located on the front of the card or board game where there are no characters, or on the front of the card or board game where there are no characters.

[0048] Example 5 differs from Example 1, Example 2, Example 3, or Example 4 in that the identification groove 5 is located on the back of the game board.

[0049] The identification groove can be placed anywhere on the back of the game board.

[0050] Example 6 differs from Example 1, Example 2, Example 3, Example 4, or Example 5 in that the identification groove 5 is located on the side of the card or board near the edge of the front or back of the card or board.

[0051] Example 7 differs from Example 1, Example 2, Example 3, Example 4, Example 5, or Example 6 in that the identification groove 5 is located on the side of the chessboard.

[0052] Example 8: A device for identifying a chessboard with a sensory marker. The identification device in this example includes a chessboard 1 as described in any of Examples 1 to 7, a marker identifier 4 for generating a signal by identifying the sensory marker 3 on the chessboard 1, and a target area 2 for placing the chessboard 1. The marker identifier 4 is disposed on one side of the target area 2.

[0053] The chess and card game 1 has an identification groove 5 at its edge, and an induction marker 3 is provided in the identification groove 5.

[0054] The sensing marker 3 is a magnet or a metal.

[0055] The mark recognition device 4 is a metal sensor, an inductive sensor, or a Hall sensor.

[0056] The area to be identified 2 has a window for the sign reader 4 to sense the sign body 3 inside the card 1.

[0057] The identification groove 5 is provided on the front, back, or side edge of the card or board game.

[0058] The working principle of this embodiment is as follows: Taking the marker body 3 as a metal body as an example, iron powder is added to the pigment used to fill the mahjong tiles. The iron powder is mixed into the pigment. The mahjong tiles with iron powder are placed in the identification area 2. A metal sensor is set on one side of the identification area 2. Since the characters are on the front of the mahjong tile, the characters are closer to the front and farther from the back. When the metal sensor is used for detection, the signal on the front of the mahjong tile is stronger than the signal on the back. The metal sensor can sense the strength of the metal signal. A metal signal strength threshold is set for the metal sensor. The threshold sensed by the metal sensor is set between the strength of the back of the mahjong tile and the magnetic field strength to distinguish the signal from the front and the back.

[0059] The following example illustrates the implementation process of this embodiment using the identification groove 5 located at the edge of the front of the game board as an example: The game board 1 moves in a certain direction in the area to be identified 2. When the game board 1 moves to the identification area of ​​the sign identifier 4 in a frontal posture, the sign identifier 4 detects the sensing sign body in the identification groove 5 on the front of the game board 1 and determines it as the front. When the game board 1 moves to the identification area of ​​the sign identifier 4 in a back posture, the sign identifier does not detect it and determines it as the back.

[0060] This embodiment can mark mahjong tiles without damaging them, distinguishing between the front and back sides, maintaining the complete shape of the tiles, eliminating splicing and adhesive seams, reducing breakage and other damage, and simplifying the mahjong tile production process. For some fragile materials, it is impossible to embed large magnets inside, and image recognition technology is expensive, color recognition is not accurate enough, and it is prone to false alarms.

[0061] Example 9 differs from Example 8 in that the identification device further includes a positioning module and a control module. The output of the positioning module is connected to the input of the control module; the input of the control module is connected to the output of the identification device; the positioning module is positioned relative to the sign identifier 4 or positioned above or below the sign identifier 4; the positioning module is used to determine whether the chess piece 1 has reached the identification area of ​​the sign identifier 4.

[0062] The positioning module is used to determine the number of cards in the game and control the card-flipping structure to flip the cards.

[0063] The positioning module is a position sensor, limit switch, proximity switch, photoelectric switch, encoder, ultrasonic sensor, or vision sensor.

[0064] The control module is a PLC, microprocessor, processor, single-chip microcomputer, industrial computer, or distributed control system.

[0065] The following describes the implementation process of this embodiment using the example of the identification groove 5 being located at the edge of the front of the card game: Card game 1 moves in a certain direction in the area to be identified 2. When card game 1 moves to the identification area of ​​the marker recognizer 4 with a frontal posture, the positioning module collects the position signal of card game 1 and transmits the collected signal to the control module. At this time, the marker recognizer 4 detects the sensing marker in the identification groove 5 on the front of card game 1 and determines it as frontal. When card game 1 moves to the identification area of ​​the marker recognizer 4 with a backal posture, the marker recognizer does not detect it and determines it as backal. The marker recognizer transmits the sensing signal to the control module. The control module receives the identification signal from the marker recognizer 4. When the received identification signal determines that card game 1 is frontal, the control module transmits the frontal signal to the card-flipping structure and controls the card-flipping structure to flip the card. When the received identification signal determines that card game 1 is backal, the control module transmits the backal signal to the card-flipping structure and the card-flipping structure does not flip the card.

[0066] Example 10: A card sorting machine, the card sorting machine including a card set with a sensor mark as described in Example 1, Example 2, Example 3, Example 4, Example 5, Example 6, or Example 7.

[0067] Specifically, the card sorting machine is a mahjong machine, a domino machine, or a tile sorting machine.

[0068] Example 11: A card sorting machine, the card sorting machine including the device described in Example 8 or Example 9 for identifying cards with sensor marks.

[0069] Specifically, the card sorting machine is a mahjong machine, a domino machine, or a tile sorting machine.
