Abstract

The present invention relates to an army chess capable of automatically distinguishing winner and loser (including distinguishing device). The appearance of the chessman of the traditional army chess is slightly improved, and each chessman is marked respectively by different characteristic symbols representing different official posts in the army, and then a digital integrated circuit is used to detect those characteristic symbols and distinguish winner and loser of both sides playing chess so as to implement automatic judgement of the army chess.

Description

Army chess with automatic judge

The present invention slightly makes improvements traditional army chess piece profile, and relates to digital circuit technique.

Known to applicant's investigation, there is not like product to occur in the market as yet, do not see the report that similar thought and method are arranged yet.

Purpose of the present invention is the victory or defeat of chess piece of crossing swords in playing chess with the military chess of electronics instrument detecting, thereby substitutes the judicator of traditional military chess in playing chess.Having remedied under the situation that does not change the military chess rule to have judge execution victory or defeat rule on the scene when traditional military chess is played chess, otherwise the defective of playing chess and can't carry out.

In order clearly to describe the present invention, define several keywords.

" military appointment ": the various roles in " army " of both sides' chess piece representative of playing chess comprise weapon;

" chess piece front ": chess piece is indicated the one side of " military appointment ";

" feature ": distinguish the sign of chess piece representative military appointment, the both sides military appointment is identical, and feature is identical;

" characteristic area ": the some in chess piece front can mark feature;

" differentiation chip ": an IC chip has a certain digital logic functions, Binary Zero 1 output that certain Binary Zero 1 input is corresponding certain;

" arbiter ": by " differentiation chip ", indicator lamp, the device of the differentiation chess piece victory or defeat that press button is formed.

At four characteristic areas of the positive definition of chess piece, as Fig. 1.The different characteristic area of different shade representatives.(unfilled corner in the upper right corner is to press the direction of hitting button for the regulation chess piece on arbiter, to avoid causing feature to be obscured because of direction is different).Characteristic area is processed into or recessed (digging a shallow hole at characteristic area) or protruding (not digging pit).Then each characteristic area can mark two kinds of different characteristics, and four characteristic areas can mark 16 kinds of different characteristics.When specific implementation, can select wherein 12 kinds of different military appointments of 12 kinds of marks arbitrarily.Example: " regimental commander " marks into Fig. 2.Its empty is partly represented convex domain, and shade is partly represented recessed zone.A kind of specific embodiments of feature mark is as follows: commandant's (convex-concave is concavo-concave), army commander's (convex-concave is concavo-convex), teacher's (convex-concave convexo-convex), brigade commander's (convex-concave convex-concave), regimental commander's (convexo-convex convex-concave), battalion commander's (convexo-convex convexo-convex), company commander's (convexo-convex is concavo-convex), platoon leader's (convexo-convex is concavo-concave), engineer's (concavo-convex concavo-concave), bomb (concavo-convex), land mine (concavo-convex convexo-convex), army flag (concavo-concave).Wherein the arrangement of characteristic area is upper left, and the lower-left is upper right, the bottom right.

The victory or defeat state of both sides' chess piece of playing chess have three kinds may: 1. the Party A wins, and 2. the Party B wins, 3. both sides negative simultaneously (both sides' chess piece identical or wherein a side be bomb).So the light on and off of available two indicator lamps show three kinds of victory or defeat states.A kind of displaying scheme of victory or defeat state is: a lamp is bright, and indication lamp a bright side bear, and the side that lamp goes out wins; Bright expression both sides are all negative simultaneously for two lamps.

Two indicator lamps and two covers and corresponding four press buttones of characteristic area size are installed on the surface of arbiter.Every cover switch and with side lamp each the first and second one side that belong to, as Fig. 3.Mouth is represented press button, and zero represents indicator lamp.Eight press buttones are connect eight tunnel inputs of differentiating chip respectively, and switch conduction is input as 1, and switch disconnects and is input as 0.The two-way output of differentiating chip is connect two indicator lamps respectively, be output as 1, indicator lamp is bright, is output as 0, and indicator lamp goes out.

In playing chess, the chess piece of crossing swords with both sides faces down, and presses simultaneously respectively and hits each side's press button.Then the pairing button of convex domain is depressed switch conduction.Recessed area relative button is not depressed, and switch disconnects.The feature of chess piece of promptly crossing swords is converted to eight inputs differentiating chip through press button.Differentiate chip simultaneously one output input correspondence is therewith arranged.Because differentiate the logic of chip is prior regulation and custom-designed, and its output strictness promptly has the light on and off mode of indicator lamp corresponding with the victory or defeat of the chess piece of crossing swords corresponding to the meaning of input representative simultaneously.So we can judge the victory or defeat of the chess piece of crossing swords by the light on and off of viewing lamp.

It below is the realization of differentiating chip.

Because the feature of chess piece converts the input of differentiating chip to through press button, protruding feature is converted into 1 input, and recessed feature is converted into 0 input.The output of chip shows by indicator lamp, and it is bright to export 1 lamp, exports 0 lamp and goes out.If so, can differentiate the enhancing Karnaugh map of chip internal logic, as Fig. 4 based on the displaying scheme of described feature mark scheme and victory or defeat state above.The binary system of left end is represented Party A's input among the figure, and the binary system of upper end is represented Party B's input.Two of output item binary systems among the figure, last bit representation Party A lamp state, back one bit representation Party B lamp state.Blank among the figure represents that this output item can be free position.

Karnaugh map thus can realize differentiating the logic function of chip by digital circuit.Less expensive and the less embodiment of investment has two kinds:

1. the PROM chip of using standard is as differentiating chip.Karnaugh map is converted into the truth table input and output respectively as address and the data of PROM,, can implements to differentiate the logic of chip the truth table PROM chip that writes direct.Annotate: the PROM chip needs greater than 256 * 2 storage capabilities.

2. the PAL chip of using standard is as differentiating chip.Realize the PAL chip logic with PAL automated programming language (as the ABEL language) and programmable device.Product term after the data of ABEL language can be used truth table or use the Karnaugh map abbreviation.Annotate: the PAL chip needs greater than eight inputs, two outputs, 34 product terms.

When manufacturing a product, select for use which kind of scheme to realize chip, by the concrete price decision of chip.

When manufacturing a product in enormous quantities, can design custom made chip voluntarily.Adopt the structure and the method for designing of PAL chip voluntarily during design chips, use with matrix and or combinations of matrices realize internal logic.Because to the low requirement of chip power characteristic and frequency characteristic, the not gate of chip internal can be realized with the simplest typical triode mode, rather than use the TTL mode to realize.Realize by a diode with matrix unit.Or matrix unit is realized by a triode or a diode.After being " product term " and " and " to the Karnaugh map abbreviation, can obtain with matrix diagram and or matrix diagram, the simple realization mode of above-mentioned in addition not gate and each unit has also just obtained the circuit diagram of entire chip.So use the said method design chips, simplicity of design, chip internal structure is regular, and manufacturing process is uncomplicated, is easy to wiring and manufacturing.Design chips can reduce chip operating voltage voluntarily, reduces the arbiter volume, thereby makes things convenient for the user.
