Example 3
The key point of the application is the mode of two-dimension code verification in class, the mode of the application does not disturb teachers at all, and only needs students to complete the verification quickly after receiving prompt information, in order to avoid the need for students to leave the seat, a large number of readers are required, but too many means too high a cost, the present application makes the best use of optical properties by placing a fixed reader 8 in a row or in a row of drawers by means of a mirror 9 with 45 ° mirrors 10, in the case of a classroom having drawers 11 arranged in parallel, a transparent resin quadrangular box 13 is provided thereunder, a plurality of openings 12 corresponding to each seat position are designed on the mobile terminal, when receiving the attendance checking instruction, the students in the row can hold the mobile terminal of the students to generate a two-dimensional code and then extend into the openings, the two-dimensional code can be read by only one reader 8 of the arrangement by a simple reflection principle. For the situation that only seats in a classroom have no drawers, the method can be similarly solved, the fixed reader 8 and the reflector 9 are both fixed on one side wall of a passageway 16 between the seats, for example, the left side wall, the reflector 9 is horizontally opened towards the right, the opening is about 1m high away from the ground, at this time, an elevation prompt board 17 can be designed behind a front-row seat 14, after a student receiving an attendance instruction generates a two-dimensional code, the student mobile terminal screen can be vertically picked up towards the left and placed at a proper height for scanning of the reader, and after the student mobile terminal receives the information, the random attendance step is completed. The fixed reader is arranged for each seat, the cost is too high, if a plurality of wireless handheld readers are arranged in a classroom, the teaching order is influenced, the classroom order is messy of seven and eight vinasse inevitably, even normal teaching cannot be carried out, the reading equipment is simplified, the classroom order is influenced minimally, unexpected technical effects are generated, and the common knowledge in the field is not available.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes in the embodiments and/or modifications of the invention can be made, and equivalents and modifications of some features of the invention can be made without departing from the spirit and scope of the invention.
