The processor is provided with 80 GPIO ports, wherein 64 GPIO ports are correspondingly connected with the second contact pieces K2 of the 64 magnetic control switches and then are grounded through a resistor R1; all the first contact pieces K1 are connected with the positive pole of the power supply through a resistor R2; all resistors R1 adopt 47K Ω, and all resistors R2 adopt 10K Ω. When one magnetic control switch K is conducted, the corresponding GPIO port is set to be at a high level, otherwise, the GPIO port is set to be at a low level.

The processor is provided with a port connecting voice module 4 outside the 64 GPIO ports, and the output end of the voice module 4 is connected with a loudspeaker 5; the voice module 4 is internally provided with an audio playing function and sends out corresponding voice according to the received signal of the processor.

In the circuit diagram of FIG. 2, the GPIO ports connected to the magnetic switch K are respectively PA 0-PA 15, PB 0-PB 15, PC 0-PC 15 and PC 0-PC 15, and the total number is 64 ports; the connection voice module 4 is provided with 4 GPIO ports PE 12-PE 15.

Further, a display screen 6 is further arranged and connected to the processor STM32F103VET 6; the timer in the processor outputs time signals to the display screen 6, and the functions of timing time display and the like are realized. The control circuit is also provided with a start key KJ which is connected with a GPIO port PE0 of the processor, and the timing is displayed on the display screen 6.

Furthermore, an executive program is arranged in the processor, and is used for judging the change of the chessmen on the chessboard and outputting corresponding signals to the voice module 4 and the display screen 6. The method for executing the program comprises the following steps: a method for judging the moving chessman, the eating chessman and the timing method are characterized in that a recording table is arranged in a processor, 64 lattices on a chessboard and symbols of corresponding chessmen are recorded by 64 storage units, the lattices without the chessmen are recorded as null values, and the initial value of the recording table is the regular recording symbols of the chess playing. The recording form can be recorded according to the symbol mark of chess, for example, the symbol of chessman of grid "a 1" is "R0", and the symbol of chessman of grid "a 8" is "R1"; in the chessman symbols, "0" represents a white chessman and "1" represents a black chessman.

For convenience of explanation, when a piece is lifted off the chessboard, it is called a lifting event; the chessboard grids corresponding to the lifted chess pieces are called raiser grids, and GPIO ports corresponding to the processor are called raiser ports; when the chessmen fall on the chessboard, the chessman falling event is called; the checkerboard lattice corresponding to the fallen chessman is called falling chessman lattice, and the GPIO port corresponding to the processor is called falling chessman port.

(1) The walking judgment method comprises the following steps: when any one of the 64 GPIO ports connected with the magnetic control switch is changed from high level to low level, a dipper event is generated, and dipper lattices and chess symbols in the record table are read; waiting for a child-falling event; when any port is changed from a low level to a high level, a falling event is generated, if the falling port and the lifting port are not the same port, namely the taken chess piece is not put back, whether the law is in accordance with the chess law moving standard is judged according to the read chess piece symbol, if not, a corresponding signal is sent to the audio module 4, and the loudspeaker 5 is made to send out corresponding voice, such as 'wrong law moving'; if the law is in accordance with the standard, modifying the value of the record table, changing the chess piece symbol of the falling chess grid into the chess piece symbol of the dipper grid, and setting the chess piece symbol of the dipper grid as a null value; if the falling check is equal to the lifting check, the chessmen are taken up and put back, and no action is taken. However, if the royal jelly translocation occurs, the second chessman is stopped after falling off, and the record table records the change of the two chessmen at the same time.

In the above method, assuming that the white square of the grid 'b 1' is right away to the grid 'c 3', the record table finds the grid 'b 1', then assigns the corresponding pawn symbol as null, finds the grid 'c 3', and rewrites the corresponding pawn symbol as 'N0'. The record table can be recorded by using a variable method.

(2) The snack judgment method comprises the following steps: reading a first dipper grid and a chess piece symbol of a record table when a dipper event occurs for the first time; reading a second dipper grid and chess piece symbols of the record table when a second dipper event occurs before a falling event does not occur; then, when a falling event occurs and the lattice of the falling is the second lifting lattice, the record table changes the chess piece symbols of the falling lattice into the chess piece symbols of the first lifting lattice, and the chess piece symbols of the first lifting lattice are emptied. In the actual chess playing process, the user takes the chess pieces according to habits, firstly lifts the chess pieces of the user, then takes the chess pieces of the opposite side away, and then puts the chess pieces of the user on the chess pieces.

(3) The timing method comprises the following steps:

after a start key KJ is pressed, all data are initialized, timing is started by a white party until a first falling event is generated, namely the white party moves a first step chess, a processor sends an instruction to pause the timing of the white party, and triggers the timing of a black party and waits for the falling event of the black party; when the black party generates a fall event, the processor sends an instruction to pause the black party timing, trigger the white party timing and wait for the white party fall event; and the process is circulated.

The method is also provided with a win-or-lose judging function, and when one party wins, the processor drives the sounder to make corresponding sound.

In order to increase the sound effect of playing chess, corresponding instructions and audio are written in the executive program and the voice module, so that a go prompt, a timing prompt, a to-be prompt, an error prompt and the like can be realized; the effects are increased, so that the children can particularly arouse the interest of playing chess and can also be guided to play chess correctly.

Regarding the circuit structure and the using method of the processor STM32F103VET6 chip, relevant data can be consulted and are not detailed here.
