The utility model discloses another embodiment still discloses a chess moving method of intelligence chess board based on RFID technique, including following step:
Acquiring photoresistance data on each grid on the chessboard panel 1, and acquiring corresponding positions of the chesses 11 on the chessboard panel 1 according to the photoresistance data;
Controlling the two-dimensional linear module to drive the RFID sensors 13 to read the chess pieces 11 on the chessboard panel 1 one by one to obtain information of the chess pieces 11;
Acquiring the last position of a chessman 11 on the chessboard panel 1, judging whether the time of the chessman 11 at the last position exceeds a first preset value, and reading the information of the chessman 11 at the last position through an RFID sensor 13 if the time of the chessman 11 at the last position exceeds the first preset value;
And judging whether the chess is effective.
Judging whether the chess playing is effective comprises the following steps: acquiring the initial position of a chessman 11 of the chess on the chessboard panel 1;
Obtaining all possible chess playing positions of the chess piece 11 according to the initial position and the information of the chess piece 11;
And judging whether the end position is at the chess playing position.
In this embodiment, due to the arrangement of the photo-resistor 6 on the board panel 1, the photo-resistor is triggered when the chess pieces 11 are placed on the board panel 1, thereby changing the photo-resistor data of the original board panel 1 at this position. Therefore, the data values of the photoresistors at the corresponding grid positions on the chessboard panel 1 are all transmitted to the controller 3, and the controller 3 can obtain which grid positions on the chessboard panel 1 have the chessmen 11 according to the photoresistor data at the grid positions of the chessboard panel 1. The positions of the chess pieces 11 on the chessboard panel 1 can be quickly determined through the arrangement of the photosensitive resistors 6, so that convenience is provided for subsequent scanning and reading of information of the chess pieces 11, and the RFID sensors 13 can be conveniently and quickly positioned at the positions of the chess pieces 11. After determining the positions of the playing pieces 11 on the board panel 1, the next step needs to obtain the corresponding information of each playing piece 11, that is, what the playing pieces on the corresponding grid on the board panel are.
The two-dimensional linear module is controlled to drive the RFID sensors 13 to read the chess pieces 11 on the chessboard panel 1 one by one to obtain information of the chess pieces 11. In this embodiment, the information of the chess pieces is acquired through the RFID sensor, specifically, the two-dimensional linear module is used to transmit the RFID sensor to the position of the corresponding chess piece, the RFID sensor is used to read the RFID tag on each chess piece to acquire the information of the chess piece at the corresponding position, and the information is transmitted to the controller. The above two steps determine the distribution state of the chessmen on the chessboard panel in the initial state.
The controller 3 then monitors the photoresistor data on the board panel 1 in real time, and when the photoresistor data on the board panel 1 changes, it indicates that there is a change in the playing pieces 11, which means that there is a move. At this time, the controller 3 obtains the position of the change of the photoresistance data on the chessboard panel 1 caused by the falling of the chess piece in the chess, namely the last position of the falling chess piece 11, and judges whether the time of the chess piece 11 at the last position exceeds a first preset value, if so, the information of the chess piece at the last position is read through the RFID sensor 13. And judging whether the time of the chess piece 11 at the last position exceeds a first preset value or not by acquiring a certain time of whether the time of the change of the photoresistor data at the last position exceeds. In this embodiment, the first predetermined value is 2 seconds, that is, when the falling chess piece is changed and the falling chess piece time exceeds 2 seconds during the chess playing process, it is determined that the user actually moves chess. The controller 3 will read the tag on each pawn 11 by controlling the two-dimensional linear module to obtain the corresponding information of the pawn 11.
Each pawn 11 has a respective playing rule, i.e. the path of each pawn 11 from one position to the next is limited. Therefore, it is necessary to determine whether the chess pieces 11 are in effective playing. This requires obtaining the initial position of the playing piece 11 of the board on the board panel 1; this may be obtained from a change in the photo-resistor data at that position, since a change in the photo-resistor data would have to be caused by the pawn being removed at the initial position. Thus, the initial position of the pawn can be determined according to the change of the photoresistor data.
Then all possible playing positions of the chess piece can be obtained according to the initial position and the information of the chess piece. This step is to calculate all possible chess-playing schemes for the chess piece, and then compare whether the end position is at the chess-playing position, if so, it indicates that the chess-playing is valid. Otherwise, the chess playing is invalid.
In the chess moving process, if multiple chess moving or changes of chess pieces at multiple positions occur within 2 seconds, the controller can acquire the changed positions of all the chess pieces through the photoresistors, confirm the position conditions of the chess pieces on a new chessboard panel and prompt a user to restore the chessboard together with the chessboard panel information before the change of the positions of the chess pieces.
