Chess piece state recognition system for intelligent turnover chessboard

The invention relates to the technical field of electric data processing, in particular to a chess piece state recognition system for an intelligent turnover chessboard, which comprises a sensing module used for acquiring the positions of a plurality of chess pieces; the power supply module comprises a built-in power supply and an oscillator; the control module is used for determining a first working mode of the magnetic field generator according to the error rate of chess piece positioning, or determining a corresponding filtering mode of the magnetic field detection assembly according to the error rate of chess piece positioning and the missing amount proportion of the electric signal, and outputting a second working mode of the magnetic field generator; the corresponding power supply frequency of a built-in power source is determined according to the missing amount proportion of the electric signals and the average delay duration of chess piece positioning, the second working mode of the magnetic field gen
