Device and method for automatically detecting surface of common mahjong tile

Abstract

The invention relates to a device and a method for automatically detecting a surface of a common mahjong tile. The device is characterized by consisting of a color detector, a singlechip and a man-machine interaction device, wherein the color detector comprises a light source and a color sensor, and the man-machine interaction device comprises a button and an indication lamp; the singlechip is connected with the color sensor, the button and the indication lamp; and the color detector is arranged in the outer wall of a mahjong tile conveying channel. The method comprises the following steps of: (1) collecting surface color information of two tiles through the singlechip in advance and storing the surface color information; and (2) when a mahjong tile machine works, analyzing and comparing the collected surface color information with pre-stored color information by the singlechip to judge the surface of the mahjong tile. Compared with the prior art, the device for automatically detecting the surface of the common mahjong tile, disclosed by the invention, has the advantages of having an exact surface detection result, configuring no dust removing mechanism, and eliminating the influence of factors, such as temperature, on detection; in addition, the mahjong tile can utilize the common mahjong tile so as to reduce the production cost.

Description

technical field [0001] The invention relates to a mahjong machine, in particular to the face detection of mahjong tiles in the mahjong machine. Background technique [0002] Mahjong machine is a leisure and entertainment tool commonly used by people. In the mahjong machines currently on the market, the mahjong tiles used are all special mahjong tiles, and permanent magnets or iron sheets are placed in the tiles. The manufacturing process is complicated and the cost is high. Because there is no uniform standard for the placement of magnets in the tiles, "cheating mahjong machines" appear in the society. Both manufacturers and users hope that ordinary mahjong tiles (without magnets or iron pieces inside) can be used in mahjong machines, but so far there is no such Mahjong machine products. [0003] There is a problem when using ordinary mahjong tiles on the mahjong machine: when sorting (shuffling) the tiles, it is necessary to detect the tile faces of the mahjong tiles movi...

Problems solved by technology

[0003] There is a problem when using ordinary mahjong tiles on the mahjong machine: when sorting (shuffling) the tiles, it is necessary to detect the tile faces of the mahjong tiles moving in the losing tile path, detect a type of tiles that "do not match the tile faces", knock them over, and make them Put it face down

The disadvantages are: ①A mahjong machine is equipped with two decks of cards with different colors, and the comparison voltage set for one deck may not be suitable for the other deck; in addition, the cards move on the conveyor belt with the conveyor belt , the distance from the sensor to each card surface cannot be absolutely the same, the same card surface, the output voltage of the sensor may also be different

②The dust-proof glass will still be contaminated with dust, and the influence of dust on the detection cannot be eliminated

The disadvantage is that the production cost is high
