Description

Chess game process monitoring system

Technical Field

The invention relates to a chess game process monitoring system.

Background

Recording each step of the game pieces while playing the game is helpful for the game. In professional competitions, the chess playing process is generally recorded by a camera. In an informal match, the chess playing process recorded by the camera is complicated and unrealistic, and the game can be repeated only by the memory of a person. For this reason, some inventors have designed a board that can sense the playing pieces. The patent application with publication number "CN 204910738U" provides an electronic weiqi chessboard, which comprises a chessboard, magnetic chess pieces, and a magnetic sensor array substrate, wherein the magnetic sensor array substrate is arranged below the chessboard, the magnetic sensor array substrate corresponds to each intersection point on the chessboard, the magnetic sensor array substrate receives a chess piece falling signal and distinguishes black and white chess pieces, and a chess piece falling point is calculated through a PC terminal. However, the intensity of magnetism is easily interfered by external factors, so that the accuracy and reliability of identifying the falling point are low.

Detailed Description

The chess related by the invention includes but is not limited to go, chess, Japanese chess, Korean chess, military chess, black and white chess, gobang, six-piece chess, checkers, Chinese checkers, beast chess, tic chess, four-piece chess, African chess, L chess and egg chess.

FIG. 1 is a block diagram of a system for monitoring the progress of a board game according to an embodiment of the present invention. As shown in fig. 1, the system comprises a pawn identification system, a pawn position sensing system and a processing system.

The chessman identity recognition system comprises NFC labels arranged on the magnetic chessmen for identifying the identity of the chessmen (each chessman has an ID number), and an NFC reader for receiving signals transmitted by the NFC labels of the chessmen and reading the ID numbers of the chessmen.

The chess position sensing system comprises a sensing circuit arranged on the chessboard, wherein the sensing circuit comprises a signal input end, a signal output end, a first circuit layer, an insulating layer, a second circuit layer and an iron bottom plate, wherein the first circuit layer, the insulating layer and the second circuit layer are arranged from top to bottom in a layered mode, and the iron bottom plate is subjected to insulating treatment. The iron bottom plate can be treated by painting and porcelain baking. The first circuit layer and the second circuit layer are printed with conductive ink. The first circuit layer and the second circuit layer comprise contacts facing the landing points on the board. The insulating layer is provided with a hole at the position of the falling point. The signal input end is connected with the contact of the first circuit layer, and the signal output end is connected with the contact of the second circuit layer. When the magnetic chess pieces are placed on the falling point, under the action of magnetic force between the chess pieces and the iron plate, two contacts at the falling point are in contact across the holes to connect the signal input end with the signal output end; after the chessman is removed, the contact is disconnected. Wherein two contacts at different landing points form different signal paths with the signal input end and the signal output end. It should be noted that it is also possible to make two contacts at the drop point by pressing, i.e. it is not necessary that the pawn has a magnetic material and the bottom plate is ferrous. This saves manufacturing costs and also makes the base plate flexible.

In one embodiment, as shown in fig. 2, the signal input terminal is connected to the positive power supply terminal as a common terminal, e.g., + 3.3V; and a signal output end connects a contact of the second circuit layer with an IO port of the processing system processor, and the processor can judge through the IO port through which contact at which drop point the signal of the signal input end is transmitted.

The processing system can identify the position information of each chessman on the chessboard according to the signal of the signal output end of the induction circuit and the chessman ID number read by the NFC reader, and stores the position information. Different chessmen are placed at the same position on the chessboard, so that different feedback information can be obtained. Therefore, the invention not only can identify the identity information of the chessmen, but also can judge the positions of the chessmen and the number of the chessmen on the chessboard.

In addition, a display screen may be provided on the board. The processing system maps the position information of the chessmen to a chessboard of the display screen for synchronous display. The processing system can also send the position information of each chessman on the chessboard to the terminal equipment through Bluetooth, so that the later-period disk copying and research are facilitated. The terminal equipment can be a mobile phone, a computer and the like. The chessboard can be also provided with a USB port, and the position information of each chessman on the chessboard can be stored on a U disk and a mobile hard disk for analysis after the game in the chess playing process.

The first circuit layer and the second circuit layer are printed by conductive ink materials, the manufacture is easy, the cost is low, the conductive ink has good printability, printed materials are flexible and various, and the chessboard can be made to be flexible. The first circuit layer and the second circuit layer are positioned in the chessboard, so that the conductive ink circuit is hidden, and the appearance of the chessboard is not affected. The on-off of the contacts of the first circuit layer and the second circuit layer at the falling point is controlled by the magnetic force between the magnetic chess pieces and the iron plate, the mode is simple, and the chessboard does not need to be improved in a complex way. By adopting the NFC technology, the problem of mutual interference when the number of the chessmen is large can be solved.
