Description

Multifunctional single-chip control chessboard

The utility model relates to a kind of Single-chip Controlling chessboard.

At present, Artificial Control chess kind and manual record chess manual are mostly adopted in various board games.The ZL92235045.0 patent has been put down in writing a kind of " Chessborad having automatic timing device ", and the CN1093476A patent application discloses a kind of " microprocessor-controlIed automatic recording device for chess manual ".The two can only be realized self-clocking respectively and remember the purpose of composing automatically, can't finish the task of self-clocking and note spectrum simultaneously.

The purpose of this utility model is to provide a kind of Single-chip Controlling chessboard with multiple functions such as self-clocking, note spectrums.

The purpose of this utility model is achieved in that it has the chessboard body and is arranged at the interior circuit part of chessboard body.Circuit part is divided into power supply and main circuit, and the chessboard body side surface has the input and output socket.Be embedded with magnetic patch with the corresponding chess piece of chessboard bottom; Main circuit partly is made up of sensor, scanning circuit, single chip part and chess clock system.Sensor adopts tongue tube, tongue tube and the corresponding setting of chess piece landing point on the chessboard, the corresponding connection of analog switch of tongue tube and scanning circuit, the corresponding connection of the bus buffer of scanning circuit, the corresponding connection of analog switch of chess clock system part with single chip part with single chip part.

For increasing its function, also be provided with interface chip and the printer port that is connected with single chip part at circuit part, can be used for connecting the expanded function card.

Chess piece landing point on chessboard is provided with light emitting diode.Form the diode display circuit that is used to show chess manual by light emitting diode.Diode display circuit is connected with interface on the interface chip.

Also be connected with printer port in single chip part,, print chess manual with enable printer.

The utility model has been owing to adopted above-mentioned setting, thereby the chess manual of playing chess can be recorded in the memory of single-chip microcomputer automatically, and chess manual is handled in real time, the self-clocking of control chess clock, and have the function of demonstrations, printing chess manual.In addition, the sensor of the utility model circuit part adopts tongue tube, has long service life, reliable operation, characteristics such as response speed is fast.The utility model is suitable for board games such as go, Chinese chess, chess.

Accompanying drawing 1 is the utility model schematic appearance;

Accompanying drawing 7 is the utility model internal structure schematic diagram;

Accompanying drawing 3 is the utility model circuit theory diagrams.

Below in conjunction with accompanying drawing the utility model is elaborated.

As shown in Figure 1 and Figure 2, in a side of chessboard body input, output socket 1 are arranged, the lower end of chess piece 2 is embedded with magnetic patch 3, and printed circuit board (PCB) 6 is arranged in the chessboard body, and the tongue tube 5 on the printed circuit board (PCB) is positioned at chessboard panel 4 times and chess piece landing point position one to one.When the chess piece that is embedded with magnetic patch drops on the chessboard, the tongue tube that is opened and closed by magnetic force control of its correspondence promptly moves.

As shown in Figure 3, scanning circuit selects 1 analog switch, W1～Wm3-8 line decoder, U13-8 line decoder, U3 bus buffer etc. to form by V1～Vn8.I/O0～I/O7 of V1～Vn meets tongue tube K, and I/O connects the P3.1 mouth of single-chip microcomputer U4, and coding input A0A1A2 connects the U3 output, and n is by the decision of tongue tube quantity, and per 8 tongue tubes meet a slice Vi (i=1～n).Output Y0～Y7 of W1～Wm (having among the figure slightly) connects the CS end of Vi, and coding input A0A1A2 connects the U3 output, and m is by the number decision of V, and a W is to using 8 V.U1 output Y0～Y7 connect Wj (CS of j=1～m), the A0A1 of U1 connects the U3 output, A2 meets the P30 of U4.The P1 mouth of U3 input termination U4, CS meets P3.4, and the effect of U3 is to be isolation or straight-through between the control input and output.Single chip part is made up of U48031 single-chip microcomputer, U5 bus buffer, U6 program storage and U7 data storage, and U4 control U5 makes the output switch of P0, can carry out instruction fetch to U6, can carry out reading and writing data to U7.Chess clock system part is made up of U2 analog switch and power supply, and P3.2, the P3.3 of the control termination U4 of U2 connect the chess clock, can control it and walk to stop and timing.U8 is an interface chip 8155, and U4 joins with single-chip microcomputer, and its PA, PB, PC make diode display circuit and expanded function clamping mouth.PRINTER printer and U4 join, and can control printer after connecing printer.

Behind the circuit electrification reset, scanning circuit is connected Vi successively under the address code control of P1 and 0 output I/Oj (j=0～7) holds to P3.1, if the K closure, the P3.1 end is low level, K disconnects, and the P3.1 end is high level, and the K closure represents that then there is magnetic patch (chess piece) the tongue tube top.Single-chip microcomputer U4 reads P3.1 end state, promptly analyzes by single chip part, and chess manual is recorded among the data storage U7, simultaneously operation result is outputed to P3.2, P3.3, with the operation of control chess clock.

Diode display circuit adopts the matrix form dynamic scan to show, the chess manual in the memory can be come out by the diode displaying that is arranged on the chessboard, promptly Light-Emitting Diode is by the luminous landing point that can show successively on the chessboard.
