Existing electronic chess-plate matrix-scanning technology not can solve Ghost Key problem, it may appear that the not position of chess piece The case where being tested with chess piece.Substantially chessboard and chess piece contact point are capacitance, Hall element, close to switch etc., are not had substantially How careful mention solves the problems, such as a line multikey, and patent of invention CN1866239A applies to decoder and solves complicated circuit code Realize the identification of chess piece position, but be the increase in cost and when ductility.
It realizes the detection of chess piece, chessboard rank scanning method, ranks crosspoint can be applied to need to switch control.It is practical new Type patent CN203090420U proposes that capacitance photosensitive switch, chess piece are put into test point, block light source, realizes the logical of switch, still It is insensitive to will appear reaction, implements the problems such as cost is excessively high, and realization is not easy.
Current various entity electronic chessboards, there are the wired one-to-one connections of upper and lower computer.Patent of invention CN101668039A realizes wireless networking connection, but only realizes chessboard and the one-to-one situation of host computer, wireless wifi networkings Mode is and can not to realize that slave computer sends the machine ID to host computer, while realizing multiple chessboards based on Transmission Control Protocol Real-time monitoring and control.
Invention content
In view of the deficienciess of the prior art, the purpose of the utility model is to provide a kind of electronic chess-plate, solve existing Chess piece detection is insensitive in technology, cost is excessively high and while cannot achieve multiple chessboards the problem of real-time monitoring and control.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution is achieved:
A kind of electronic chess-plate, including chess piece detection circuit, the chess piece detection circuit are the matrix type circuit that ranks intersect; The first diode is provided on each row of the matrix type circuit, the anode of the first diode passes through first resistor and electricity respectively Source is connected;Each ranks infall of the matrix type circuit is provided with the second diode and magnetic reed switch, the magnetic red Switch is connected with the anode of the second diode, and the cathode of the second diode is connected by second resistance with power supply.
Further, further include control unit, wireless serial module, wireless communication module, host computer, computer, it is described Chess piece detection circuit is connected with control unit, and module is connected described control unit with host computer by radio communication, described Control unit is connected by wireless serial module with computer.
Further, the host computer includes server and display system, the wireless communication module by internet with Server is connected, and the server is connected with display system.
Further, described control unit is microcontroller.
Compared with prior art, the present invention having the following technical effect that:
The ranks infall that matrix type circuit is arranged in the utility model on chessboard is provided with diode and magnetic reed switch, solution It has determined the problem of often row can only be by next button in the prior art, i.e. " Ghost Key " problem, and practical magnetic reed switch, has passed through strong magnetic The mode of attraction makes switch be closed, high sensitivity;
The control unit of the utility model uses microcontroller, reduces cost;
The utility model realizes the real-time monitoring and control of one-to-many chessboard, each chessboard has the ID number of oneself, solution Traditional chessboard of having determined can not achieve while realize the one-to-many real time monitoring problem of multiple chessboards.

Explanation is further explained in detail to the particular content of the present invention below in conjunction with attached drawing.
Specific implementation mode
It is laterally row that row, column in the present invention, which refers in attached drawing, is vertically row.
Specific embodiments of the present invention are given below, it should be noted that the invention is not limited in implement in detail below Example, all equivalent transformations made on the basis of the technical solutions of the present application each fall within protection scope of the present invention.
Embodiment:
A kind of electronic chess-plate, such as Fig. 2, including chess piece detection circuit are present embodiments provided, chess piece detection circuit is ranks The matrix type circuit of intersection;The first diode is provided on each row of matrix type circuit, the anode of the first diode leads to respectively First resistor is crossed with power supply to be connected;Each ranks infall of the matrix type circuit is provided with the second diode and magnetic red Switch, the magnetic reed switch are connected with the anode of the second diode, and the cathode of the second diode passes through second resistance and power supply It is connected.
Chess piece in the present embodiment is designed as passive chess piece, and the bottom of chess piece is equipped with patch magnet so that chess piece has It is magnetic.
Since classical keyboard scanning circuit is there are a significant problem " Ghost Key ", i.e., go out chess in the position detection of not chess piece The presence of son, the utility model are realized the one-way conduction of electric current, have been prevented " Ghost Key " by the way that diode is arranged at test point Occur, realizes the detection of each chess piece position.
Switch in the utility model uses magnetic reed switch, encounters strong magnetic sensitivity height, the sensitive of circuit may be implemented and open Close break-make.
The present embodiment is by taking chessboard of go as an example, and totally nine ten points, each point are a test point, each test point on chessboard That is the corresponding ranks infall with chess piece detection circuit, when magnetic chess piece is close to magnetic reed switch, magnetic reed switch is closed, and row are dragged down Voltage;When magnetic chess piece leaves magnetic reed switch, switch is opened.
As shown in Figure 1, further including control unit, wireless serial module, wireless communication module, host computer, computer, chess piece Detection circuit is connected with control unit, and module is connected control unit with host computer by radio communication, and control unit passes through Wireless serial module is connected with computer.
Control unit in the present embodiment is microcontroller.
As shown in figure 3, microcontroller is connected by I/O port with chess piece detection circuit, when magnetic reed switch closing, row are dragged down Voltage, it is low potential to be input to I/O port, and I/O port is set as high-impedance state, can read analog electrical energy;Magnetic reed switch is opened, and is not had Input, input are initial pull-up initial voltages.When row input is low level, it was demonstrated that have chess piece above test point;Work as row Input then proves exist without chess piece above test point when being high level.The position of chess piece existing record on software, therefore, root According to Chinese chess rule, whenever having the change of low and high level on chessboard, so that it may be sentenced with being recorded according to existing chess piece position Disconnected is which chess piece is moved, and change is saved as new record, and the record of each step also forms whole Zhang Jiqi Spectrum.
Host computer includes server and display system, and wireless communication module is connected by internet with server, service Device is connected with display system.
Such as Fig. 4, the wireless serial module in the present embodiment carries out initial setting up by computer to control unit, that is, selects Communication pattern is wifi patterns, and wifi titles and password is arranged so that control unit can by radio communication module with mutually Networking is connected.
The ID of each chessboard can also be passed through channel radio by the present embodiment by multiple chessboards by the ID of each chessboard of setting Letter module is uploaded to server, and the implementing monitoring of multiple chessboards simultaneously may be implemented in this way.
