Description
The present invention relates to a kind of microprocessor-controlIed self-recording unit, particularly microprocessor-controlIed automatic recording device for chess manual.
In chess (go, Chinese chess, chess etc.) match, the record of chess manual is a very important job.Even playing chess of both sides at ordinary times, the record chess manual also is highly significant.Its both sides that can help to play chess descended the analysis of chess crown's discs, also can be used for long preservation.
This work still adopts artificial or artificial intervention to carry out up to now basically.Wherein can be divided into following several mode again:
1, manual record: when playing chess, will move process record on paper with the special messenger.This is the main method of all matches so far or the employing of playing chess at ordinary times.Because this is an effort, repetition and the work that easily makes mistakes, except regulation game, few people do.
2, computer recording: when making in this way, chessboard and chess piece all are to be presented on the screen of computer.The both sides that play chess can utilize its positions of moving of device input such as keyboard, Genius mouse.Computer can be noted.But both sides do not use real chessboard, chess piece owing to play chess, and are very inconvenient, and in fact few people use.
3, switch record: make in this way, play chess both sides still with under the chess piece on general chessboard, a row switch (see figure 1) respectively is equipped with at the two ends of different is chessboard.We are called capable switch (1) and row switch (2) respectively with this two row switch.The quantity of switch and position be with chess piece may son in the quantity of chessboard (3) and position one to one.The person of the playing chess chess crown that whenever makes a move presses the switch of the pairing row and column in chess piece (4) in-position.This signal is delivered to corresponding controller (5) and is noted.If exist several its sons all to be movable to the situation of that ad-hoc location, the situation of Chinese chess for example, the person of playing chess also must start other switch, tells that controller is which chess piece has moved.This method is also very inconvenient.
" microprocessor-controlIed automatic recording device for chess manual " is exactly to invent specially for head it off.It can automatically write down the process that the both sides that play chess play chess, and stores.Exteriorly, this device and general chess tool have no difference: chessboard, the cover chess piece and the clock that clocks.But owing to chessboard, chess piece are all made through particular design, the variation of chess piece position on chessboard can be detected automatically, intervention that need not be artificial.Cooperation just can automatically store the process of moving with the control corresponding circuit.
The present invention is achieved by the following technical solutions: as shown in Figure 2, microprocessor-controlIed automatic recording device for chess manual is by the special chess piece that has metal material, the back side is fixed with the special chessboard of sensing circuit (8), MCU Microprocessor Control Unit (6), chess piece detection line (7), ancillary equipment (9) is formed, the input of the output termination chess piece detection line (7) of sensing circuit (8), the input of the output termination MCU Microprocessor Control Unit (6) of chess piece detection line (7), MCU Microprocessor Control Unit (6) links to each other with ancillary equipment (9), it is characterized in that: sensing circuit (8) is to use sheet metal, the array type capacity sensing circuit (8) that fibrous material is made, this array type capacity sensing circuit (8) is connected to form by electric capacity and diode.On the chessboard each can the son the position all the useful metal sheet be attached to the electric capacity of making on the fiberboard, each electric capacity has two exits, all same exits that are in the electric capacity of delegation are all coupled together by a lead, and guide chess piece detection line (7) into, another exit of each electric capacity all is connected to two diodes: diode A and diode B, the positive pole of diode A connects electric capacity, minus earth, and the negative pole of diode B connects electric capacity, anodal then link to each other with the positive pole that is positioned at the diode B that same other electric capacity of row is connected, and guide chess piece testing circuit (7) into by lead.If chessboard may the position of son the capable and M of N row are arranged, total lead number of introducing chess piece testing circuit (7) is N+M.
Fig. 3 is the schematic diagram of one 2 * 2 chessboard, is used to illustrate the operation principle of array type capacity sensing circuit (8).In this schematic diagram, chess piece only may be placed in four positions of two row, two row intersection points, its variable dynamic condenser is not used (10), (11), (12), (13) expression, two row select decoder to use (14), (15) expression respectively, two column selection decoders are used (16), (17) expression respectively, and square-wave generator is represented with (18).In order to measure the electric capacity of (10), decoder (14), (16) will be connected, and all the other end points are in the state of shutoff.At this moment, the signal of square-wave generator (18) will pass through (14), (10) and (16) arrive output.Because the existence of diode (19), (20), possible path (14), (11), (13), (12), (16) of another of signal will be blocked, and like this, the accuracy of measurement will be guaranteed.In order to detect the existence of each position chess piece on the chessboard, as long as we select decoder that corresponding row and column is connected successively, and the voltage of measuring output then gets final product.The advantage of this array type capacity sensing circuit is the quantity that it can significantly reduce required control line.Suppose that chessboard manages to make do the position of son that the capable and M of N row are arranged, the sum of required control line will be M+M.If each position is all introduced control line respectively, its sum then is N * M.
