Description

Technical Field

[0001] The present invention relates to chess and card related fields, in particular to an intelligent chess and a positioning and tracking method thereof. Background Art

[0002] Chinese chess is an ancient competitive game with a broad base among the people and many fans. In the process of learning, it is necessary to record the score and review the game. The traditional method is to record manually, which is very time-consuming and laborious. With the development of smart devices, many game software have appeared on computers and mobile devices. However, playing chess on computers or mobile devices does not have the experience of a real chessboard, and watching the screen for a long time is not good for vision health.

[0003] In view of this, some people in the prior art have proposed a product concept of a smart chessboard, which is to install an electromagnetic transmitter in the chessboard and place an electromagnetic resonator in a specific chess piece. The disadvantage of this is that specific chess pieces must be used. In view of the disadvantages of the above-mentioned prior art, it is necessary to make further improvements.

[0010] As a preferred technical solution of the present invention, the chess pieces are opaque.

[0011] A positioning and tracking method for intelligent chess, comprising the following steps:

[0012] S1: The infrared transmitting unit emits infrared light at a set time interval to scan each chess piece placement point on the chessboard. The infrared receiving unit at the blocked chess piece placement point and the unblocked chess piece placement point receives different light intensities, thereby obtaining information about the chess piece placement point.

[0013] S2: The microcontroller detects whether the distribution of chess pieces at the current drop point has changed compared with the results of the last infrared light scan, and then records the data of chess piece movement.

[0014] As a preferred technical solution of the present invention, during detection, priority detection can also be performed based on the prediction results of the chess intelligent algorithm stored in the microcontroller.

[0015] The present invention has the following advantages: The present invention provides an intelligent chess based on infrared emission and receiving technology and a positioning and tracking method thereof, which can locate and track chess pieces of any opaque material, and convert chess records into electronic records while retaining the real chess game experience, so as to facilitate retention and user review and summary.

[0018] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0019] It should be noted that the directions or positional relationships indicated by terms such as “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0020] See also Figure 1A smart chess device includes a chessboard device and chess pieces 7. The chessboard device includes a chessboard shell 1 and a chessboard back cover 2. The chessboard shell 1 and the chessboard back cover 2 are connected by locking screws 6. The chessboard shell 1 is provided with chessboard drop points 8 arranged in a matrix. The chess pieces 7 are placed on the chessboard drop points 8. A plurality of signal transmitting and receiving units 3 corresponding to the chessboard drop points 8 are provided between the chessboard shell 1 and the chessboard back cover 2. A host control module 4 and a warning module 5 are also provided between the chessboard shell 1 and the chessboard back cover 2.

[0021] The host control module 4 is connected to a power supply module.

[0022] The signal transmitting and receiving unit 3 includes an infrared transmitting unit and an infrared receiving unit.

[0023] The host control module 4 includes a microcontroller and a signal switching circuit. The infrared transmitting unit is driven by the transmitting end of the microcontroller, and the output signal of the infrared receiving unit is connected to the receiving end of the microcontroller after amplification and filtering.

[0024] The chess piece 7 is opaque. When the chess piece 7 is dropped, it only needs to be placed on the drop point 8 without center alignment.

[0025] A positioning and tracking method for intelligent chess, comprising the following steps:

[0026] S1: The infrared emitting unit emits infrared light at a set time interval to scan each chess piece placement point 8 on the chessboard. The infrared receiving unit at the blocked chess piece placement point 8 and the unblocked chess piece placement point 8 receives different light intensities, thereby obtaining information about the chess piece placement point 8 where the chess piece 7 is placed.

[0027] S2: The microcontroller detects whether the distribution of the chess pieces 7 at the current placement point 8 has changed compared with the last infrared light scanning result, and then records the movement data of the chess pieces 7.

[0028] More preferably, during detection, priority detection can be performed based on the prediction results of the chess intelligent algorithm stored in the microcontroller.

[0029] During the implementation of the present invention, the infrared emitting unit corresponding to each chessboard device's drop point 8 sequentially emits infrared light at a fixed frequency according to the program setting;

[0030] When a chess piece 7 is placed at the drop point 8, the opaque chess piece 7 will reflect the infrared light, and thus be received by the infrared receiving unit corresponding to the drop point 8. When no chess piece 7 is placed at the drop point 8, the infrared light completely radiates outward, and the corresponding infrared receiving unit cannot receive the returned infrared light.

[0031] The infrared receiving unit converts the received light intensity signal into a corresponding electrical signal, which is then filtered and amplified before being input into the microprocessor for program identification. The microprocessor unit identifies the current chess game progress based on the changes in the electrical signal collected by the infrared receiving unit at the global drop point 8, and records and stores the chess records.

[0032] When the chessboard device detects the infrared reflection signal, the chessboard device determines whether a chess piece 7 is placed at each placement point 8 according to the intensity of the reflection signal.

[0033] When the chessboard device performs detection, it first determines based on time. Only when the same path point is continuously judged as "having chess piece 7" within a few seconds can it be determined that the chess piece 7 is placed at the drop point 8.

[0034] At the beginning of the game, it is first determined whether the chess pieces 7 are placed correctly. If they do not match the preset initial state, the warning module 5 emits an audible and visual signal to remind the chess player.

[0035] When it is detected that the chess player's move does not comply with the rules, the warning module 5 also sends out sound and light signals to remind the chess player.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
