[0028] DETAILED DESCRIPTION

[0029] The present invention is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those of ordinary skill in the art, several changes and improvements can also be made without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0030] Example 1

[0031] like Figure 1 As shown, a smart chessboard with multi-attribute recognition provided by the present invention includes a chessboard shell 1, a chessboard cover 9 is detachably mounted on the chessboard shell 1, and a receiving space for receiving a sensor system is formed on the chessboard cover 9 and the chessboard shell 1. The chessboard cover 9 includes a chessboard surface, and the sensor system in the receiving space can sense each chess piece position on the chessboard surface and generate a sensing signal, thereby generating an indication of the chess piece falling out of position.

[0032] Furthermore, the sensing system includes multiple sensors, one of which is installed in the accommodating space below each chess piece position, and any sensor can sense, identify and detect the properties of the sensed object located above it. All the sensors in the accommodating space together constitute a complete array sensing group, and any sensor in the array sensing group can simultaneously sense, identify and detect the properties of the sensed object and generate signals in the out-of-position state.

[0033] The inventor believes that by forming an array sensing group through the cooperation of sensors installed corresponding to each chess piece position on the chessboard surface within the accommodating space, it is possible to sense the falling position of the chess piece at each position on the smart chessboard, thereby sensing, identifying and detecting the attributes, coordinate information, and falling position status of each chess piece on the smart chessboard, thereby enhancing human-computer interactivity.

[0034] Example 2

[0035] like Figure 2 As shown, according to a smart chessboard with multi-attribute recognition provided in Example 1, the sensor includes a first lamp bead 2, a first photoresistor 3, a Hall element 4, an MCU control circuit 5, a second photoresistor 12, and a circuit board. The first lamp bead 2, the first photoresistor 3, the Hall element 4, and the second photoresistor 12 are respectively connected to the MCU control circuit 5 and the circuit board, and the MCU control circuit 5 is connected to the circuit board.

[0036] Specifically, the accommodating space includes a first accommodating space and a second accommodating space, the first accommodating space is located above the second accommodating space, and the first accommodating space and the second accommodating space can be used as the installation base of each component on the sensor, so as to completely surround each component of the sensor and realize the protection of each component on the sensor. The circuit board is a PC circuit board 6, which is installed at the bottom of the first accommodating space, and the first lamp bead 2, the first photoresistor 3, the Hall element 4 and the second photoresistor 12 are all welded and connected to the PC circuit board 6. The MCU control circuit 5 is installed at the bottom of the chessboard housing 1 and is electrically connected to the PC circuit board 6 to realize the transmission of signals between the MCU control circuit 5 and the PC circuit board 6.

[0037] like Figure 3 As shown, the MCU control circuit 5 includes a wireless communication module, an LED driving module, a sensing signal input or output management module, a power management module, and a voice recognition and external speaker module. It can ensure that various signals of the sensor are distinguished and various signals received by the sensor are presented in a visual manner. The MCU control circuit 5 uses an embedded program to determine and calculate the properties of the sensed device and the signal status of the sensor.

[0038] like Figure 2 As shown, the chessboard cover 9 is made of a transparent material and can transmit visible light. The Hall element 4 and the second photoresistor 12 are both fixedly installed in the first accommodation space, and the Hall element 4 is located at the upper edge of the PC circuit board 6, and the second photoresistor 12 is welded in the middle of the upper side of the PC circuit board 6. The second photoresistor 12 is a photoresistor component that can sense the visible light on the chessboard surface. The Hall element 4 is a full-level (N / S) magnetic induction electronic component that can sense the magnetic sheet device located above the sensor and can transmit the signal to the MCU control circuit 5 and the circuit board.

[0039] The second accommodation space is a completely enclosed space, and external light cannot penetrate into the second accommodation space. The first lamp bead 2 and the first photoresistor 3 are both fixedly mounted on the top of the second accommodation space, and both the first lamp bead 2 and the first photoresistor 3 are located on the lower side of the PC circuit board 6. The first photoresistor 3 is located in the middle of the second accommodation space, and the first lamp bead 2 surrounds the circumference of the first photoresistor 3. A magnetic induction switch is also provided in the second accommodation space, and the magnetic induction switch can close or open the first photoresistor 3 under the action of an external magnetic force. Thereby realizing the sensing of the chess piece with a magnetic sheet above the sensor.

[0040] Specifically, the first photoresistor 3 is a photoresistor component, and the first lamp bead 2 is an LED lamp bead. The magnetic switch includes a first photoresistor housing 7 and a magnetic ball 8, the magnetic ball 8 has a permanent magnetic property, the magnetic ball 8 is placed directly below the first photoresistor 3, the first photoresistor housing 7 is installed on the periphery of the first photoresistor 3 and surrounds the first photoresistor 3, and the contour of the first photoresistor housing 7 is adapted to the magnetic ball 8.

[0041] The chess piece with the magnetic sheet is located above the sensor. When the force exerted by the chess piece on the magnetic ball 8 upward is greater than the gravity of the magnetic ball 8 itself, the chess piece has strong magnetism. When the force exerted by the chess piece on the magnetic ball 8 upward is less than the gravity of the magnetic ball 8 itself, the chess piece has weak magnetism.

[0042] In actual operation, the chess piece with the magnetic sheet is located above the sensor, and the first lamp bead 2 is in a normally open state. When the chess piece has a strong magnetism, the magnetic ball 8 can be physically attracted to the induced device with the magnetic sheet. The magnetic ball 8 moves upward under the strong magnetic effect of the chess piece until it contacts the first photoresistor housing 7 and completely blocks the first photoresistor 3, so that the visible light emitted by the first lamp bead 2 cannot be sensed by the first photoresistor 3, and the first photoresistor 3 cannot send out a sensing signal.

[0043] When the chess piece located above the sensor is not magnetic or has weak magnetism, the magnetic ball 8 is located below the first photoresistor 3, and the first photoresistor 3 can receive the visible light emitted by the first lamp bead 2, thereby generating a sensing signal and transmitting the sensing signal to the MCU control circuit 55 and the circuit board, thereby realizing the generation of a switching signal of the first photoresistor 33.

[0044] Furthermore, the magnetic ball 8 includes an N pole and an S pole, and the magnetic ball 8 can reverse and move up and down in the second accommodating space. A guide groove for guiding the movement of the magnetic ball 8 is formed in the second accommodating space. When the magnetic ball 8 is acted upon by the magnetic force of the chess piece located above the sensor, the magnetic ball 8 can move upward under the guidance of the guide groove, thereby improving the working stability of the magnetic induction switch, thereby ensuring the reliability of the switching signal generated by the first photoresistor 3.

[0045] The inventor believes that nine transmission signals can be generated by the cooperation of the Hall element 4, the second photoresistor 12, the first photoresistor 3, the second lamp bead 13 and the magnetic ball 8, which are as follows:

[0046] The Hall element 4 does not generate a signal, the first photoresistor 3 generates a signal, and the second photoresistor 12 generates a signal. This state is the same as not placing a chess piece on the sensor, so it is not counted in the sensor's transmission signal;

[0047] The Hall element 4 generates an N-pole signal, the first photoresistor 3 does not generate a signal, and the second photoresistor 12 generates a signal;

[0048] The Hall element 4 generates an S-pole signal, the first photoresistor 3 does not generate a signal, and the second photoresistor 12 generates a signal;

[0049] The Hall element 4 generates an N-pole signal, the first photoresistor 3 generates a signal, and the second photoresistor 12 generates a signal;

[0050] The Hall element 4 generates an S-pole signal, the first photoresistor 3 generates a signal, and the second photoresistor 12 generates a signal;

[0051] The Hall element 4 does not generate a signal, the first photoresistor 3 generates a signal, and the second photoresistor 12 does not generate a signal;

[0052] The Hall element 4 generates an N-pole signal, the first photoresistor 3 does not generate a signal, and the second photoresistor 12 does not generate a signal;

[0053] The Hall element 4 generates an S-pole signal, the first photoresistor 3 does not generate a signal, and the second photoresistor 12 does not generate a signal;

[0054] The Hall element 4 generates an N-pole signal, the first photoresistor 3 generates a signal, and the second photoresistor 12 does not generate a signal;

[0055] The Hall element 4 generates an S-pole signal, the first photoresistor 3 generates a signal, and the second photoresistor 12 does not generate a signal.

[0056] The inventor believes that the sensor can be designed in a matrix combination according to the scene usage and product requirements, so as to form an array sensing group under the framework of a complete control platform, which can be used in scenes that require distinguishing multiple signals, such as smart chessboard recognition and detection of chess piece attributes and out-of-position states. The inventor also believes that the PC circuit board 6 of the array sensing group can be a whole circuit board or multiple circuit boards; the first lamp bead 2 located in the second accommodation space can also be used alone or in common.

[0057] Example 3

[0058] like Figure 2 As shown, according to an intelligent chessboard with multi-attribute recognition provided in Example 2, a second lamp bead 13 is installed in the first accommodating space, the second lamp bead 13 is an LED lamp bead, the second lamp bead 13 is welded and connected to the upper side of the PC circuit board 6, and the second lamp bead 13 is electrically connected to the MCU control circuit 5.

[0059] The second lamp bead 13 surrounds the circumference of the second photoresistor 12 , and the second lamp bead 13 is at least one independent lamp bead, each of which is monochrome or RGB color, so as to visually convey different system instructions of each corresponding signal to the user.

[0060] The second lamp beads 13 emit visible light of different colors according to different instructions of the MCU control circuit 5, and can be displayed on the chessboard cover 9.

[0061] A second photoresistor housing 14 for shielding visible light emitted by the second lamp bead 13 is arranged around the second photoresistor 12. The second photoresistor housing 14 surrounds the second photoresistor 12, and the second photoresistor housing 14 is close to the bottom surface of the upper cover plate. It is mainly used to shield the light interference generated by the second lamp bead 13 when it is on, and can better perceive the changes in natural light on the surface of the upper cover plate.

[0062] The inventor believes that the number of the second lamp beads 13 can fully reflect the system instructions corresponding to different sensors.

[0063] Example 4

[0064] like Figure 2 and Figure 4 As shown, according to embodiments 1, 2, and 3, a smart chessboard with multi-attribute recognition is provided, which also includes object tags, and the object tags form chess pieces of the smart chessboard and are used in conjunction with the smart chessboard. By setting the attributes of the object tags, chess pieces formed by object tags with different attributes can generate different signals when being sensed, identified, and detected by the array sensing group located in the smart chessboard, thereby causing the second lamp beads 13 to emit light of different colors and appear on the chessboard cover 9, so that chess players can quickly distinguish them, thereby improving the human-computer interaction performance.

[0065] like Figure 2 and Figure 4 As shown, the chess piece formed by the object tag includes a label upper cover 10 and a label lower cover 11. The label upper cover 10 is made of an opaque plastic material, and the label lower cover 11 is an opaque plastic part made of ABS plastic or a translucent plastic part made of ABS transparent light-conducting plastic. Therefore, the properties of the chess piece formed by the object tag are translucent or opaque. When the chess piece with the translucent label lower cover 11 is placed on the chess piece position, the second photoresistor 12 of the sensor located below the chess piece position senses light and generates a signal; when the chess piece with the opaque label lower cover 11 is placed on the chess piece position, the second photoresistor 12 of the sensor located below the chess piece position cannot sense light, so no sensing signal is generated.

[0066] The chess piece formed by the object tag is equipped with a magnetic sheet 15 or without a magnetic sheet 15, and the magnetic sheet 15 includes an N-pole single-pole magnetic sheet and an S-pole single-pole magnetic sheet. The N-pole single-pole magnetic sheet includes an N-pole single-pole black magnetic disc and an N-pole single-pole rubber weak magnetic disc, wherein the N-pole single-pole black magnetic disc has a strong magnetism and the N-pole single-pole rubber weak magnetic disc has a weak magnetism.

[0067] The S-pole single-pole magnetic sheet comprises an S-pole single-pole black magnetic disc and an S-pole single-pole rubber weak magnetic disc. The S-pole single-pole black magnetic disc has a strong magnetism, and the S-pole single-pole rubber weak magnetic disc has a weak magnetism.

[0068] Specifically, when the upward force exerted by the magnetic sheet on the magnetic ball 8 is greater than the gravity of the magnetic ball 8 itself, the magnetic sheet has a strong magnetism. When the upward force exerted by the magnetic sheet on the magnetic ball 8 is less than the gravity of the magnetic ball 8 itself, the magnetic sheet has a weak magnetism.

[0069] Therefore, the chess pieces formed by the object tags have two categories: N-pole strong magnetism, S-pole strong magnetism, no magnetism; N-pole weak magnetism, S-pole weak magnetism; light-transmitting, opaque, a total of two categories, combined to form nine types of chess pieces, and cooperate with the array sensing group to form nine different sensing signals, as shown below:

[0070] When the chess piece is non-magnetic and translucent, the Hall element 4 does not generate a signal, the first photoresistor 3 generates a signal, and the second photoresistor 1212 generates a signal. This state is the same as not placing a chess piece above the sensor, so it is not counted in the sensor's transmission signal.

[0071] When the chess piece has N-pole strong magnetism and is light-transmissive, the Hall element 4 generates an N-pole signal, the first photoresistor 3 does not generate a signal, and the second photoresistor 12 generates a signal;

[0072] When the chess piece has a strong S-pole magnetism and is light-transmissive, the Hall element 4 generates an S-pole signal, the first photoresistor 3 does not generate a signal, and the second photoresistor 12 generates a signal;

[0073] When the chess piece has N-pole weak magnetism and is light-transmissive, the Hall element 4 generates an N-pole signal, the first photoresistor 3 generates a signal, and the second photoresistor 12 generates a signal;

[0074] When the chess piece has a weak S-pole magnetism and is light-transmissive, the Hall element 4 generates an S-pole signal, the first photoresistor 3 generates a signal, and the second photoresistor 12 generates a signal;

[0075] When the chess piece is non-magnetic and opaque, the Hall element 4 does not generate a signal, the first photoresistor 3 generates a signal, and the second photoresistor 12 does not generate a signal;

[0076] When the chess piece has a strong N-pole magnet and is opaque to light, the Hall element 4 generates an N-pole signal, the first photoresistor 3 generates no signal, and the second photoresistor 12 generates no signal;

[0077] When the chess piece has a strong S-pole magnet and is opaque to light, the Hall element 4 generates an S-pole signal, the first photoresistor 3 generates no signal, and the second photoresistor 12 generates no signal;

[0078] When the chess piece has a weak N-pole magnetism and is opaque, the Hall element 4 generates an N-pole signal, the first photoresistor 3 generates a signal, and the second photoresistor 12 does not generate a signal;

[0079] When the chess piece has a weak S-pole magnetism and is opaque to light, the Hall element 4 generates an S-pole signal, the first photoresistor 3 generates a signal, and the second photoresistor 12 does not generate a signal.

[0080] The inventor believes that the chess piece formed by the object tag, in cooperation with the array sensing group, can realize all chess movements with less than nine types of chess pieces, and can sense, identify and detect the properties and falling and leaving positions of the chess pieces.

[0081] Example 5

[0082] like Figure 1 and Figure 2 As shown, according to a smart chessboard with multi-attribute recognition provided by Example 4, a capacitive sensing circuit is installed on the PC circuit board 6, and the capacitive sensing circuit is connected to the MCU control circuit 5. The capacitive sensing circuit has a close-range spatial sensing characteristic. And the capacitive sensing circuit includes an active capacitive sensing circuit and a passive capacitive sensing circuit.

[0083] Taking the active capacitive sensing circuit as an example, if the chess piece has the properties of a passive active capacitive sensing circuit, it can trigger the active capacitive sensing circuit and generate a sensing signal; if the sensed device does not have the properties of a passive active capacitive sensing circuit, it cannot trigger the active capacitive sensing circuit and does not generate a signal.

[0084] The distance between the passive capacitive sensing circuit and the active capacitive sensing circuit is the same, and the chess pieces can be set to be sensed or not sensed by the passive capacitive sensing circuit.

[0085] Combined with the nine signals in Example 4, the sensor of this solution can generate 18 sensing signals, which can be applied to fields such as artificial intelligence robots and can also be applied to intelligent chess games.

[0086] The inventor believes that when the sensor is applied to intelligent chess games, since the chess pieces are in contact with human hands, it is preferred to use the active capacitive sensing circuit principle; in other scenarios where there is no contact with the human body, it is preferred to use the passive capacitive sensing circuit principle.

[0087] Example 6

[0088] like Figure 5 As shown, according to embodiments 1, 2, 3, 4, and 5, a smart chessboard with multi-attribute recognition is provided, and chess is now used as an example for explanation:

[0089] Taking Chinese chess as an example; the chess pieces are divided into fourteen sub - categories including rook (chē), knight (mǎ), elephant (xiàng), advisor (shì), general (shuài), pawn (zú), cannon (pào) in Chinese chess, with seven major categories of chess piece attributes. Each major category contains two同族 sub - categories and is uniformly bound with an ID code. The MCU system determines the black and red sides based on the first - hand and second - hand players in the game, and judges the different attributes of the chess pieces according to the ID numbers of the chess pieces.

[0090] Taking chess as an example; the chess pieces are divided into ten sub - categories including rook (red), rook (black), knight (red), knight (black), bishop (red), bishop (black), queen (red), queen (black), king (king). Among them, rook (red), rook (black), knight (red), knight (black), bishop (red), bishop (black), queen (red), queen (black) have independent ID codes, and king (king) has a shared code. For the shared code of king (king), the MCU system can directly judge the king (red) and king (black) sides through the first - hand and second - hand players in the game.

[0091] The chessboard is an intelligent electronic chessboard made of an array induction group. When any chess piece falls directly above the sensor of the array induction group, the array induction group generates a signal, and through the MCU control system or the comprehensive signal obtained by the sensor, it calculates core information such as the attributes of the target chess piece, the coordinate position, and the state of the chess piece's placement and removal, so as to carry out human - machine battles and network battles. At the same time, when a player accidentally touches and moves a non - target chess piece during the game, the system will automatically remind and inform the player of the coordinates and attribute names of the accurate target chess piece, so as to enhance the human - machine interaction and reduce the decline in the game experience caused by misoperations.

[0092] The inventor believes that taking Chinese chess as an example has automatic recognition and sensing technology, and its technology and applications are not limited to this.

[0093] In the description of this application, it should be understood that the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0094] The specific embodiments of the present invention have been described above. It should be understood that the present invention is not limited to the above - mentioned specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which does not affect the essence of the present invention. Without conflict, the embodiments of this application and the features in the embodiments can be combined with each other arbitrarily.
