Detailed ways

The specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

Please refer to FIG. 1 , the first embodiment of the present invention provides a laboratory management system 1 , including an attendance module 11 , an assignment module 12 , a storage module 13 and a two-dimensional code display module 14 .

The time attendance module 11 is used to scan the code through the preset program on the mobile terminal to record the user's sign-in information.

The allocating module 12 is used for allocating corresponding computers to corresponding users based on the sign-in information.

The storage module 13 is used for real-time storage of each computer-generated data, and generates corresponding trace files based on user operations, and associates the trace files and computer-generated data with the check-in information, the The trace file records the operation process of the user in the corresponding time.

The two-dimensional code display module 14 is used to provide a display screen to display the two-dimensional code for checking in, and the two-dimensional code for checking in is displayed by the LED display device. The user can only scan the two-dimensional code based on the preset program on the mobile terminal to display the two-dimensional code. The two-dimensional code on the module 14 is used for punching and signing in, realizing paperless operation.

It can be understood that the preset program is the program software installed on the mobile terminal in the laboratory management system 1, and the preset program is used to scan the QR code selected by the laboratory to complete the check-in operation, specifically, in In this embodiment, the mobile terminal is a mobile phone.

It can be understood that the allocation module 12 can be used to allocate the corresponding computer. After the user completes the check-in through the attendance module 11, the allocation module 12 can unlock the corresponding computer based on the check-in information and start the computer. Unlocked computer codes can be obtained based on the preset procedures described above.

It can be understood that the storage module 13 can record data generated by computer operation in real time, for example, writing data of monitoring programming software (such as java, c language). The storage module 13 can also acquire the operation process codes so far according to the user's operation commands, and generate corresponding trace files. For example, record the user's operation sequence of selecting functions and software with the mouse, typing with the keyboard, etc., and convert them into corresponding text or video expression files (that is, the above-mentioned trace files), which is convenient for users to review, especially in computer experiments. The course teaching carried out in the classroom, by generating the trace file, facilitates the user's later self-review and improves the efficiency of classroom teaching.

Please refer to Figure 2, the preset program also includes:

An image scanning module 100, configured to scan a corresponding two-dimensional code to obtain a corresponding two-dimensional code image;

The anti-remake module 200 is used to detect whether the current two-dimensional code image is a remake based on the remake detection method;

The alarm module 300 is configured to issue an alarm when it is detected that the image is a copy.

It can be understood that the image scanning module 100 calls the camera of the mobile terminal to obtain the current two-dimensional code image after clicking the scanning operation on the interface through a preset program.

It can be understood that the anti-copying module 200 can perform image recognition based on the currently acquired two-dimensional code image, and detect whether the currently acquired two-dimensional code image is a copied image based on the image-based copying detection method, so as to prevent the user from remotely obtaining the two-dimensional code. The fraudulent behavior of remote sign-in after the image has improved the supervision system of attendance.

It can be understood that due to the wave interference effect between the camera's photosensitive element and the display, there will be obvious colored stripes on the picture obtained by retaking the image on the computer or mobile phone screen, which is called "moiré". On equipment such as digital cameras or scanners, the high-frequency interference fringes that appear on the photosensitive element are high-frequency irregular fringes that make the image appear colored. However, moiré usually appears on the edge of the image, resulting in a large change in the pixel gradient of the region where the moiré appears in the image, that is, a non-linear change in the gradient value of the image surface. Then the anti-copying module 200 can perform photocopying detection based on the pixel gradient of the image surface, for example, by extracting the statistical value of the gradient feature of the image surface, and designing an image classifier based on LibSVM to distinguish the photoshopped image from the natural image. For another example, based on identifying the surface features of the image, that is, directly identifying whether the image has moiré features can also identify whether the current image is a remake.

It can be understood that, in this embodiment, since the two-dimensional code display module 14 is based on the two-dimensional code for sign-in displayed on the display screen, when the user takes a photo of the two-dimensional code, there will be a more obvious moiré in the obtained picture. Moiré pattern can ensure the accurate recognition of the anti-copying module 200, making full use of the feature of "moiré pattern" in the image captured by the camera, and avoiding the fraudulent behavior of remote sign-in.

It can be understood that the alarm module 300 is for alarming when duplicated images are encountered, reminding the laboratory manager of fraudulent behavior, and facilitating the management of the laboratory by the manager.

It can be understood that the data saving module 132 is usually used to save the work data generated by the user through specified work software, for example, code programs written and obtained in programming software, data such as word files and excel tables generated in office software.

It can be understood that the binding module 133 can associate the saved work data and trace files with the check-in information, that is, each user can save the work performed by the associated individual in the laboratory each time, and form a link with the check-in information. One-to-one correspondence, and directly store with sign-in information, without creating an additional work account, saving the space occupied by the database and the amount of calculation for calling data, and improving the management efficiency of the laboratory.
