Description

Technical Field

[0001] The invention belongs to the technical field of color vision testing, and specifically refers to an automatic chess shuffling machine and a chess shuffling method for color vision testing. Background Art

[0002] In the field of color vision testing, FM-100 color chess is a widely used and important testing tool. However, the traditional operation process of FM-100 color chess has many problems that need to be solved.

[0003] During the preparation stage of the examination, the scrambling and restoring order of the pieces of the FM-100 color chessboard is completely dependent on manual operation. The operator needs to move the pieces one by one to achieve scrambling and restoring order, which is extremely inefficient. Especially in environments such as medical examination institutions where a large number of FM-100 color chessboards are used for color vision examinations, this process consumes a lot of time and energy, seriously hindering the efficient advancement of color vision examinations.

[0004] In addition, to ensure the accuracy of the FM-100 color chess inspection, it is necessary to confirm that the order of the bottom of the chess pieces meets the inspection set rules. Currently, this confirmation is done by manually flipping through the bottom of the chess pieces. This process not only greatly reduces the efficiency of the preparation work, but also is prone to various errors due to the uncertainty of human operation. The operator may misread the order of the chess pieces due to lack of concentration, or accidentally change the original position of the chess pieces during the flipping process, which will have a serious impact on the accuracy of the inspection results.

[0005] At the same time, frequent manual contact seriously damages the chess pieces of the FM-100 color chess. Since the chess pieces have to be manually shuffled and flipped before each inspection, the long-term contact friction makes the coating or material on the surface of the chess pieces very easy to wear. Once the chess pieces are worn, their color display effect may change, which will directly interfere with the accuracy of color vision inspection, and also shorten the service life of the chess pieces, increase the cost of use and waste of resources.

[0006] More importantly, in the process of using FM-100 color chess pieces for inspection, in order to facilitate the confirmation of the color chess piece sorting, the color chess piece number will be set at the bottom of the color chess piece to facilitate the judgment of whether the sorting is correct. Since the tester manually sorts the chess pieces, in order to ensure the authenticity of the inspection results, it is necessary to arrange special personnel to supervise the tester to prevent the tester from looking at the serial number at the bottom of the chess piece. This undoubtedly increases the additional labor cost, and this supervision method is difficult to be foolproof. If the tester looks at the serial number at the bottom of the chess piece while the supervisor is not paying attention, the entire inspection result will be completely meaningless, resulting in all previous preparations and inspection processes being in vain.

[0007] In summary, the existing operation methods for FM-100 color chess have serious deficiencies in efficiency, accuracy, chess piece protection, and inspection supervision. There is an urgent need for a device that can automatically complete the chess piece shuffling and sorting confirmation functions to solve these problems and improve the quality and efficiency of color vision inspection.

When the target block number of the color chess piece 3 is greater than the current block number, record the operator of the current block 21 as 1; when the target block number is equal to the current block number, record the operator of the current block 21 as 0; when the target block number is less than the current block number, record the operator of the current block as -1; when there are no chess pieces in the exchange area 212 of the block 21, record the operator of the current block 21 as X;

[0046] Step S3: Obtain the operator sequence. The color chess driving mechanism 41 pulls the color chess piece 3 with an operator of 0 in the block 21 into the compartment 211 of the block 21;

[0047] Step S4: Obtain the operator sequence. Starting from block 0, take two adjacent blocks as a group, and the blocks within the group do not interleave. Identify the number A of combinations of "1, X", "X, -1", and "1, -1" of the operators of adjacent blocks, and feedback the serial number of the combination;

The automatic chess shuffling machine for color vision testing according to claim 1, characterized in that: The identification device (5) is a radio frequency identification (RFID) scanner or a near field communication (NFC) scanner, and each of the color chess pieces (3) is provided with an identification chip, and the identification chip is a corresponding RFID tag or NFC tag; the first adsorption component (423) and the second adsorption component (412) both use negative pressure adsorption, and the housing (1) is provided with an air pump and an electrically controlled valve for providing negative pressure.

7. The automatic chess shuffling machine for color vision testing according to claim 1, characterized in that: The identification device (5) uses a color identification sensor for identifying the color of the color plate (32); the first adsorption component (423) and the second adsorption component (412) both use electromagnetic adsorption, and the chess shell (31) of the color chess (31) is made of a metal that can be adsorbed by a magnet.

8. The automatic chess shuffling machine for color vision testing according to claim 1, characterized in that: The housing (1) is provided with buttons (7) and a screen (8). The screen (8) is used to display the chess washing progress and prompt operation information. The buttons (7) include a power button, a chess washing button, a stop chess washing button, and a sorting and checking button.

9. A chess shuffling method, applied to an automatic chess shuffling machine for color vision testing as described in any one of claims 1 to 9, characterized in that: It includes the following steps: Step S1: Sequentially assign block numbers to each block (21), with the lowest block number being 0. Assign chess piece numbers to each colored chess piece (3). The identification device (5) identifies the color of the chess piece (3) in each block (21) currently, obtains the current sorting of the chess piece (3), and randomly generates a chess washing sorting. The chess washing sorting consists of the number of each chess piece and the block number corresponding to each chess piece number; Step S2: Obtain the target block number of the chess piece (3) in each block (21). When the target block number of the chess piece (3) is greater than the current block number, record the operator of the current block (21) as 1. When the target block number is equal to the current block number, record the operator of the current block (21) as 0. When the target block number is less than the current block number, record the operator of the current block as -1. When there are no chess pieces in the exchange area (212) of the block (21), record the operator of the current block (21) as X; Step S3: Obtain the operator sequence. The chess piece driving mechanism (41) pulls the chess piece (3) in the block (21) with the operator 0 into the compartment (211) of this block (21); Step S4: Obtain the operator sequence. Starting from block 0, take two adjacent blocks as a group, and the blocks within the group do not intersect. Identify the number A of combinations of "1, X", "X, -1", and "1, -1" of the operators of adjacent blocks, and feedback the serial number of the combination; Step S5: Starting from block 1, take two adjacent blocks as a group, and the blocks within the group do not intersect. Identify the number B of combinations of "1, X", "X, -1", and "1, -1" of the operators of adjacent blocks, and feedback the serial number of the combination; Step S6: When A > B, switch to the left gear position and control the corresponding serial number chess piece swapping mechanism (42) to start. When A < B, switch to the right gear position and control the corresponding serial number chess piece swapping mechanism (42) to start; Step S7: Repeat the above steps S3 - S6 until the operator sequence is entirely composed of X, and prompt through the screen (8) that the chess washing operation has been completed.
