An automatic chess referee device based on eddy current sensor

Abstract

The invention discloses an automatic chess judgment device based on eddy-current sensors. The automatic chess judgment device comprises a chessboard body, a judgment unit and a timer, eddy-current sensor arrays are arranged on the portions, corresponding to all intersection points, of the back face and chessboard face of the chessboard body, and metal sheets with different heights are embedded in chess pieces; the judgment unit comprises a voltage amplifier, an A / D converter, a wireless receiving and sending module, the eddy-current sensor arrays and a microcontroller I, wherein the microcontroller I is connected with the A / D converter which is connected with a filter through the voltage amplifier, the filter is connected with a detector which is connected with the eddy-current sensor arrays, the microcontroller I controls the eddy-current sensor arrays to conduct distance detection on the metal sheets embedded in the chess pieces so as to detect corresponding types and positions of the chess pieces, and the microcontroller I transmits corresponding information to the timer through the wireless receiving and sending module to enable the timer to complete corresponding action. The automatic chess judgment device based on the eddy-current sensors is simple in structure and accurate in positioning.

Description

technical field [0001] The invention relates to an automatic chess referee device based on an eddy current sensor. Background technique [0002] The timing and notation work in current chess (Chinese chess, international chess) competitions is mainly done manually, and there are many disadvantages. Even if the notation has computer-assisted notation, it needs to be entered manually. The workload is large, time-consuming, laborious, and The error rate is high, and the timing must be operated by the chess player himself. In view of the above problems, the present invention provides a radio frequency identification type chess automatic notation device, which can automatically notate notation, timekeeping and counting seconds. Contents of the invention [0003] In order to solve the above-mentioned problems, the present invention proposes a chess automatic referee device based on eddy current sensors. This device can realize automatic notation, timekeeping and seconds countin...
