Background

Military chess is one of the chess games well received by China. Military chess can be played by two methods, one is four-player, and the other is two-player. When four players play, the four players occupy four corners on the chessboard and are divided into two sides, and two opposite alliances and the other two parties resist and cooperate with each other to fight; when two players play, they occupy the upper and lower corners of the chessboard to fight each other.

Whether four or two persons are confronted with the dark chess, a very important role, namely a notary is needed to judge the sizes of the chess pieces of the two confrontation parties. Without the notary role, the four-player mode or the two-player mode cannot be played in a dark-chess manner.

In daily life, many people enjoy playing military chess games very much. In the game, the two confrontation parties carry out attack and defense by arranging troops, and after the troops are arranged, the two confrontation parties need to have a neutral notary as a judge. However, in life, there may be a case where there is no notary of military chess, both game parties want to play games but only give up playing because of no notary, and there may be a case where two persons want to play military chess but not notary, but only make a lot out of reception, although there is interest. At this time, if we can have a machine, the two opponent parties can automatically judge the sizes of the chessmen of the two opponent parties by only putting the chessmen on the machine. Therefore, the development of a military chess with notarization device is a concern.

The utility model discloses in the preferred embodiment, still be provided with a power end 6 on the bottom plate 3, a power adapter is connected to power end 6, provides working power supply for bottom plate 3 through power adapter.

The utility model discloses in the preferred embodiment, set up a voltage conversion circuit on the bottom plate 3, power end 6 is connected to voltage conversion circuit's input, and voltage conversion circuit's output inserts in the acquisition circuit as external power source.

In a preferred embodiment of the present invention, the voltage of the external power source of the input acquisition circuit is 3V.

In the preferred embodiment of the present invention, the resistance of the reference resistor R1 is 10 Ω.

Specifically, after different voltages are acquired, the voltage signals are acquired by an AD conversion module of the single chip microcomputer, the AD conversion module can convert analog signals into digital signals, and then a series of binary digital signals are converted into decimal numbers.

In the selected singlechip, a specific calculation formula is as follows:

specifically, it can be calculated according to the above formula that if the military chess is placed on the circuit board, the conversion result is 0. If the mine is placed on the circuit board, the result of the conversion is (0.227/3) × 4096 — about 310. By analogy, if the command is placed on the circuit board, the conversion result is (2.508/3) × 4096-3424 or so. If no chess pieces are placed on the circuit board, the conversion result is (3/3) × 4096 ═ 4096 or so.

The chessmen are in contact with the conductors on the circuit board, and the resistors are arranged in the chessmen, so that the resistors are connected in series in the circuit when the chessmen are placed on the circuit board.

The 10K ohm resistance is fixed, where it cannot be too small, which results in excessive current and increases the overall power consumption of the device. The resistance put into the chessman is not fixed, and is the value I chooses here:

military chess: 0 omega

Land mines: 820 omega

The engineer: 2K omega

Row length: 3.6K omega

And continuous growth: 5.1K omega

And operation: 7.5K omega

Round growth: 10K omega

The sojourn: 15K omega

Master length: 22K omega

Military officer: 33K Ω

Commander: 51K omega

Bomb: 120K omega

It can be seen that if the military chess is placed on the circuit board, the collected voltage is 0V. The mine was placed on a circuit board and the voltage collected was 3V [820/(10000+820) ] -0.227V. It can be concluded that when the command is placed on the circuit board, the voltage is 3V × 51000/(10000 +51000) ], 2.508V. If no chess pieces are placed on the circuit board, the collected voltage is 3V. Different resistances can thus be distinguished by different voltages.

Specifically, the relationship between the size of the military chess pieces and the conversion result is as follows:

and if the conversion result is less than 150, judging that the chessmen on the circuit board are military flags.

And if the conversion result is 150-510, judging that the chessmen on the circuit board are landmines.

If the conversion result is 511-910, the chess pieces on the circuit board are judged to be the soldiers.

And if the conversion result is 911-1270, judging that the chessmen on the circuit board are in the row length.

And if the conversion result is 1271-1600, judging that the chessmen on the circuit board are continuously long.

And if the conversion result is 1601-1930, judging that the chessmen on the circuit board are longer.

And if the conversion result is 1931-2300, judging that the chessmen on the circuit board are in a group length.

If the conversion result is 2301-2680, the chessmen on the circuit board are judged to be the longest.

If the conversion result is 2681-3020, the chessman on the circuit board is judged to be teacher's length.

If the conversion result is 3021 to 3320, the chessmen on the circuit board are judged to be military leader.

If the conversion result is 3321-3600, the chess pieces on the circuit board are judged to be commanders.

If the conversion result is 3601-3950, the chessmen on the circuit board are judged to be bombs.

If the conversion result is larger than 3950, it is determined that no chess pieces are on the circuit board.

Based on the series of conversion results, the judgment of the response given in the program can judge the win or lose of the size.

The beneficial effects of the utility model reside in that:

the utility model discloses simple structure conveniently carries, the utility model discloses settle the unanimous metal base of the nevertheless resistance difference of outward appearance under the piece, when putting into the device to this piece, turn into the digit that can compare to resistance, then judge this digit size through the procedure in the singlechip to accomplish the big or small condition of antagonism both sides piece.
